Vehicle developed OBD-II code P052E related to crankcase ventilation/PCV system malfunction. Issue causes improper crankcase pressure, rough idle, oil vapor smells, and check engine light. Independent research shows this is a common failure on 2015–2017 Mercedes C300 models. Repair requires replacement of crankcase vent/PCV assembly. This appears to be a premature emissions system failure.

CHECK ENGINE LIGHT appeared on dash at approximately 72k miles. Had code read and diagnosed by certified mechanic and he had an active code P06DA00(this code signifies an electrical fault, open circuit, or high resistance in the circuit for the oil pump control valve on vehicles with two stage oil pump, which can lead to incorrect oil pressure, which can cause engine damage if not addressed). Vehicle was taken to Harriman Mercedes in New York. They did not acknowledge an active code but wanted to diagnose and repair a stored code for a small evap leak, which was rectified with a new gas cap. After prying about the P06DA00 code, they finally admitted it did have a stored code but to ignore it because it had something to do with domestic and foreign car engine computers issues. How do you ignore an active code with a potentially serious engine issue and told to ignore it. I know for a fact that this is a common problem with these 2.0L engines in these cars for many years.

I have noticed a recurring issue during the colder months where there is a strong gas smell inside the cabin, and I have also observed fuel dripping into the engine compartment. This issue seems to occur primarily in winter conditions. I was surprised to find that there has been no official recall or service bulletin addressing this concern, especially given the potential safety implications.

Upon purchasing my 2016 C300, I starting experiencing a right pull whenever I press on the brakes. I was very concerned as I use this vehicle to assist with dropping and pick up of my 2 grandchildren. The more I drove the car, the more unsafe especially when I attempt to bring my car to a stop. I took the car to a local mechanic and I was advice to take it to a Mercedes dealership. The mechanic also advice that it was an issue with the REAR SUB FRAME. A week later I took the car in to Mercedes as suggested and a day later I received a call and video from Mercedes that the subframe was broken and that is why I am getting that hard pull whenever I brake. Mercedes also stated that the control arm bracket is barely on and it is causing the vehicle to flex.

My car on has 80,000 miles and the camshaft position sprockets needs to be replaced. I went to a Mercedes dealer and this was the diagnostic. This causes the engine light to come on, hesitant engine, low acceleration while driving. The dealer said it will cost $8,000 to be replaced and still can go bad. There was a recall for this issue before. RecallCampaign2015100007

Error Code: P052E Crankcase Ventilation Valve Malfunction. Part was changed before and Engine Light still comes on. Vehicle is available for inspection. Vehicle was inspected by Mercedes Dealership several times. Part is on Backorder Nationwide. Car Does not pass emissions inspection, therefore cannot renew registration either for several months.

FUEL/PROPULSION SYSTEM

An independent service center diagnosed my car as having a fuel leak stemming from the fuel rail and fuel injectors. This is a fire hazard due to a gas leak. There is a gas smell in the interior cabin that I noticed approximately one month ago. I believe this pertains to NHTSA ID #21V961, and I would like NHTSA to consider including my VIN in this recall.

Smells like gas strong
Mar 08, 2025
During cold weather there is always a gasoline smell when starting the engine that eventually goes away. On 01/20/2025 the smell was so intense that I decided to stop the engine and leave the car outside the garage just in case. Upon opening the hood, I noticed an amount of a type of liquid similar to gasoline right on the undercarriage protector covers. I could not reach with my hands but instead I used a wood stick that I had in the garage. I reached the liquid and submerged the stick for like 10 seconds and pulled it out. When I smelled it, it indeed smelled like gasoline. I took the stick to the back patio and lighted it up and as I suspected, the tip of the stick lighted up like a torch. I called a nearby mechanic and made an appointment to check it out and today (01/23/2025) I am bringing it in. I went to Youtube and found numerous videos showing this "well known issue" with some of the fuel lines in this type of vehicle which I believe is a tremendous hazard. Just imagine that when I turned the engine up on 01/20/25 the engine could had gone up in flames burning not only the vehicle, but my entire house with maybe my family inside? Please take serious note on this issue and try to come up with a mandatory solution for the problem. I will let you guys know the findings from the Mercedes mechanic once the job if completed in case you need more information. Thanks

Smells like gas and my auto group gave me a recall campaign bulletin showing recall for my make model and year (Mercedes c300 2016), but my VIN doesn’t show it as being covered by that recall.

--The sunroof glass suddenly shattered without any prior warning while the vehicle was in driving on the road. Some of the broken glass pieces scattered throughout the interior of the car. --The sudden shattering of the glass roof created a hazardous situation for the driver and passengers. Although no one was injured, we were shocked and initially thought it might be an explosion or gunfire. Additionally, the tiny glass shards is very dangerous. --We have called dealer and they said there might be several similar cases reported. --The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives, but I have called dealer and insurance company. --There were no warning lights, messages, or symptoms indicating a potential failure before the incident. The glass shattered unexpectedly and spontaneously while driving.

Front Stationary Sunroof Panel (between the windshield and the sunroof) deteriorating and cracking in the middle. I've read about a recall on previous year models that will extend to this year model or even further year but waiting on this recall to reach my vin number. I've seen same model year in other states have this issue resolved with the recall update in Feb 2024. This is related to the NHTSA Recall ID: 23V854.

Just purchased this vehicle in Utah, was driving from Utah to Idaho on the interstate at 80mph when all of a sudden my sunroof opened up with high winds and blew right off. Luckily nobody was behind me but I’ve been driving 2 hours without a sunroof due to weak glue/manufacturing defect

STEERING
10 complaints
I am writing to formally report the premature failure and subsequent replacement of the electronic rack and pinion on my 2016 Mercedes-Benz C300 4Matic sedan. This repair was performed at Sears Imported Autos on 4/19/2024, at a cost of $5,840.14. Invoice number at Sears Imported Autos is XXX. My vehicle, VIN [XXX] , had only 74,427 miles at the time of the failure. The failure of a critical steering component at such a low mileage is highly unusual and, I believe, directly attributable to a latent manufacturing defect. I have recently become aware of a prior recall (NHTSA Campaign Number 18V850000) concerning the electronic power steering rack on these EXACT vehicles. While I acknowledge that my vehicle VIN was not included in the official scope of the previous NHTSA recall, the nature and timing of my component's failure strongly mirror the documented issues of MY power steering failure. Mercedes-Benz USA Customer Care Center just informed me that my VIN does NOT qualify for the recall, but they did NOT say the failure on my car was a different part. The fact that the very same exact part failed so prematurely, a component that is expected to last for the lifetime of the vehicle under normal conditions, points to a systemic quality control issue beyond the scope of the original recall. The recall should be expanded to include my VIN and likely a few others. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

EPS- Electric Power Steering failed while driving causing hazardous and dangerous conditions. While unable to steer the vehicle it crossed the median into oncoming traffic barely avoiding an accident and endangering my life and life of other drivers and passengers. Unlike on hydraulic systems where in case of defective pump it is still possible to steer the car, this electric steering it was impossible to control even to load the vehicle on the tow truck. Terrible technology or design, most importantly it is NOT SAFE !

While driving, my vehicle suddenly shut down in the middle of traffic without any prior warning. I was left stranded in the hot sun, fearing for my safety and praying that I wouldn’t be rear-ended. The incident was not only terrifying but also unacceptable for a vehicle of this caliber. I contact Mercedes customer service. I spoke to a representative name Stephanie. She called the Mercedes dealership service department in Columbus, Ga and received confirmation that my car did shut completely down on me without warning. Stephanie stated she will notate the incident. I told her there should be more than just a notation because this put me in grave danger, not only was my life in jeopardy this is a serious potential threat to others.

The sunroof locked open during a road trip. I am mechanically inclined, so adding lubricant and driving through a low pressure air front caused the sunroof to shut. Had I been in an emergency, not mechanically inclined, or if this happen during inclement weather or to a little old lady this would have been a severe issue causing the vehicle to become inoperable due to rain or snow entering the cabin and reducing visibility, and damaging the electronic components in the vehicle's cabin. This is also a safety hazard to the the drivers health in conditions of smog, extreme low temperature, animal attack or if there was an assault from a criminal with ill intentions.

My car had a problem about starting so I went to see a dealership. They got the job done and charged me $320. I just realized that in the invoice they used recall campaign to cover my car. However, they charged me $320 for no reason. Also, I never got any letter regarding to recall. How did they used recall campaign on my car?? And I recently had a sunroof derailed and they used the campaign again but charge me $2700 for it. And of course my car isn’t in their recall list?? I never got a letter as well

The rear differential failed, causing both rear axles to be broken and the vehicle to lose all propulsion on a city road. A noise in the drivetrain under acceleration was first reported to a dealership in Nov 2023 about five months prior to the failure, but the report was dismissed as tire slippage and not addressed further. Then the failure occured in April 2024, and the vehicle was towed to a dealership and repaired out of warranty at great expense. There were no warning lights or symptoms immediately prior to the failure.

While driving my 2016 Mercedes-Benz C300 on Route 12 in Utica, NY around 8:10 PM on May 29, 2025, the panoramic sunroof spontaneously exploded while in the tilted vent position. It sounded like a gunshot and sent glass raining into the cabin, causing multiple cuts to my hand, ear, arm, and lower back while I was driving. The shock nearly caused me to lose control of the vehicle. Conditions were clear and dry, around 60°F, and I was driving about 50–55 mph. I have reported the incident to Mercedes-Benz USA (Case #14443457). This is a serious safety hazard, and I am concerned about residual glass in the vehicle’s ventilation system and potential future injuries. I am also concerned about paint and interior damage from the explosion.

WHILE DRIVING ON THE HIGHWAY, I HEARD A LOUD NOISE THAT, ON FIRST IMPRESSION, LED ME TO BELIEVE SOMEONE FIRED A GUNSHOT AT AND STRUCK MY VEHICLE. UPON LOOKING UP, I IMMEDIATELY NOTICED IT WAS NOT A GUNSHOT BUT INSTEAD THE GLASS TO THE FRONT PORTION OF MY PANORAMIC SUNROOF HAD SPONTANEOUSLY SHATTERED AND FLEW COMPLETELY OFF THE VEHICLE. THIS FLYING GLASS FLEW DIRECTLY BACKWARDS AND COULD HAVE POSED A DEADLY RESULT FOR THE NUMEROUS DRIVERS TRAVELING BEHIND ME. THERE WERE NO FLYING OBJECTS OR OTHER DANGEROUS INSTRUMENTS THAT STRUCK THE VEHICLE BUT THE SUNROOF SPONTANEOUSLY, ON ITS OWN, SHATTERED AND COMPLETELY DETACHED FROM THE VEHICLE. UPON SUBSEQUENT ONLINE INVESTIGATION, I LEARNED THIS VERY ISSUE HAS BEEN EXPERIENCED BY OTHER MERCEDES BENZ DRIVERS, WITH THE SUNROOFS SPONTANEOUSLY SHATTERING AND FLYING OFF. DESPITE PURCHASING A EXTENSIVE WARRANTY AT THE TIME OF PURCHASE, BODY WORK, INCLUSIVE OF GLASS REPLACEMENT, IS NOT COVERED. CONSEQUENTLY, I WAS FORCED TO FILE AN AUTO INSURANCE CLAIM, WHICH REQUIRED AN IMMEDIATE $500 DEDUCTIBLE TO BE PAID TO ENABLE THE REPAIR COMPANY TO ORDER THE REPLACEMENT GLASS. THIS REOCCURRING ISSUE MOST CERTAINLY REQUIRES A RECALL FOR VEHICLES CONTAINING THIS PROBLEMATIC SUNROOF. IT IS NOT ONLY A DANGER TO THE DRIVER OF THE VEHICLE, BUT ALSO TO ALL OTHERS TRAVELING ON THE ROAD.

THE PANORAMIC SUNROOF SLIDING CLIPS ARE PLASTIC AND BREAK. WHILE GOING DOWN THE ROAD THE ROOF LIFTED WHEN I ATTEMPTED TO CLOSE IT. THE PLASTIC CLIPS BROKE THAT SECURE THE SLIDE RAIL AND GLASS TOGETHER.

HEARD SOMETHING CRACK AND THE FOUND LATER PLASTIC PIECES OF THE SHOE ON THE RIGHT SIDE ON THE SUNROOF IN THE RAIL OF THE SUNROOF. IT WAS THE RAIL GUIDE SHOE. THE MECHANIC ADVISED ME THE ENTIRE ROOF WOULD NEED TO COME UP, INCLUDING HEADLINER. HE ALSO SAID YOU'D NEED TO REPLACE RAILS, WHICH SOUNDS A BIT MUCH FOR A PLASTIC SHOE. I AGREED, IT'S RIDICULOUS THAT THESE ARE MADE OF PLASTIC. 4 THOUSAND DOLLARS TO FIX IT. I BEEN SEEING A LOT PEOPLE COMPLAINING ABOUT THE SAME PROBLEM.

I have a 2016 C300 that was diagnosed with a severe brake booster issue. Last week, I had to brake hard while traveling 65 mph on a highway and they failed; luckily I was able to avoid catastrophe by maneuvering around the obstacle. I researched to see if this was a known issue and learned that some Mercedes models between 2008-2012 had recalls due to brake booster corrosion issues, but Mercedes might have a worse issue than just a few models prior to 2012, based on my experience!

The contact owns a 2016 Mercedes-Benz C300. The contact stated while crossing a pay toll, she was depressing the brake pedal to the floorboard but the vehicle failed to decelerate and rear-ended into a truck. The contact stated no warning light was illuminated. The contact stated no one was injured nor sought medical attention. The contact stated there was no need to call and report the incident, no police report was filed. The contact stated she continued driving to her destination. The contact stated when she stepped out of the vehicle, she noticed the bumper, the grill, and the Mercedes-Benz logo and bracket were fractured. The contact took the vehicle to a local dealer, where it was diagnosed with needing the brake pads, the rotors, the bumper, the Mercedes-Benz logo, and the bracket to be replaced. The vehicle was repaired. The contact asked the dealer what was the cause of the failure but the dealer did not have a diagnosis for the failure. The manufacturer had not been informed of the failure. The failure mileage was approximately 49,900.

On [XXX] I was on my way home from running errands and proceeded to open my panoramic sunroof using the button inside of my car. When I arrived home, I pressed the button again to close the sunroof. As it began closing and went into the forward position, once it reached the top of my roof, the back of the sunroof would not go down back into place. This left the sunroof open in the venting position. On [XXX], I went to RBM of Atlanta where I purchased the vehicle [XXX] to report and resolve the issue. The service center was rude and brushed off my concerns. They were able to manually close the sunroof as a temporary fix and informed me not to use the sunroof button, but they were unable to assist with my diagnostic or repair inquires. However, one of the service employees advised that this was a common issue that was previously recalled. I immediately contacted MBUSA where I was connected to a Sales rep at RBM of Atlanta who also informed me that this was a common issue. Today, 07/24/2024, I went to a diagnostic appt. at RBM of Alpharetta and was told by the service advisor that there had been at least 9 recalls for this issue and my sunroof has all of the defective parts that were supposed to be replaced when these recalls took place. He also informed me that I should have been advised of this issue before the vehicle was sold to me. I have attempted to resolve the issue with RBM on five different occasions to no avail. My vehicle is available for inspection upon request. I believe this issue puts myself and others at risk because if the entire sunroof is defective, it can detach at anytime and possibly hit and injure someone while I'm driving, which would make me liable. As stated previously, I have received confirmation that my sunroof is defective and should have been added to one of the several recalls. The last multi-point inspection was done nearly a year before I bought the car and a repair diagnosis was done today. There were no other signs.

My brother was driving his car on the highway and out of no where the sunroof literally exploded causing the glass to shatter on him and the front panel to detach from the vehicle. Swinging and hanging on the side of the car causing dents, scratches, and chips making this a safety hazard. Thank god my brother was able to safely merge over to the emergency lane without causing any accidents my brother was shocked with glass raining down on him when this happened but he wasn’t injured glad no one was injured in this incident because anything could’ve happened. A lot of Mercedes have a recall for the sunroofs front panel which causes it to detach from the vehicle while driving which I believe is what happened here this can cause a significant safety risk because the person might get jump scared causing him/her to swerve into other cars beside them. My brothers year and model is on the same recall list but his vin number was not included on the recall. Which leads me to think this was a mistake on the manufacturer end. We spoke to Mercedes USA (Manufacturer) And a Mercedes dealership said they cannot help us out or do anything for us to help us fix the sunroof because his vin doesn’t have that recall I asked if there could be a possibility that the car has that recall but it’s just not listed under and the recall they said that could be a possibility but they won’t fix it unless it’s under the vin which just now leaves us to pay 6-7 thousand dollars out of pocket to fix the sunroof, dents, and scratches that were causes by the sunroofs front panel flying off the car. There was not any warning lights or symptoms of this happening and I know for a fact a rock did not hit because the sunroof was closed at the time that this happened and we would have felt and heard it. Our only option now is to file claim with NHTSA and wait to hear back. The vehicle is available to see upon request.

the Burl wood trim panel on the interior doors are deteriorating , the drivers side panel is deteriorating to the point that it looks like acid is eating away at the material there is red markings showing .. i find this could be a safety hazard as it could eat away at the door itself. i have pictures of evidence. there was a recall on Mercedes E class during the same years i purchased my car, my car is the C-class which was not part of the recall, but falls into the same category as time frame of purchase. Mercedes told me to contact you. i look forward to your response as this is a safety concern thank you

I BOUGHT MY 2016 MERCEDES C63S AMG FROM A DEALER IN EDMOND, OKLAHOMA (JACKIE COOPER BMW) AND THEY SOLD ME THE CAR WITH LESS THAN 10% TREAD LEFT ON THE TIRES. SHORTLY AFTER THE PURCHASE I CALLED THE DEALER FOR ASSISTANCE AND THEY FLAT OUT DENIED ANY WRONG DOING. THEY CLAIMED THEY DID A "RIGOROUS INSPECTION" BUT SOMEHOW THE TIRES THAT WERE DOWN TO THEIR WEAR BARS PASSED IT. TO MAKE MATTERS WORSE, I PURCHASED A $4100 TIRE/WHEEL PACKAGE FROM THEM AND THEY ALSO HAVE NOT ACTIVATED THE SERVICE (AFTER 23 DAYS OF PURCHASE) SO I CANNOT GET NEW TIRES PUT ON WITHOUT PAYING AN EXTRA $1200 OUT OF POCKET FOR THE HIGH PERFORMANCE TIRES THAT THE CAR REQUIRES. MANAGEMENT HAS NOT RETURNED ANY OF THE CALLS & THE SALES AGENT (BRYAN LEONARD) ALSO HAVE NOT BEEN VERY HELPFUL. NEARLY A MONTH LATER AFTER THE PURCHASE THE CAR IS STILL SITTING IN THE GARAGE WITH TWO BUSTED TIRES & NO WAY TO REPLACE THEM UNDER WARRANTY BECAUSE THE DEALER IS REFUSING TO EXPEDITE THE WARRANTY ACTIVATION. I FINALLY GOT TIRED OF WAITING SO I TOOK THE HIT FOR THE FRONT TWO TIRES AND PAID A MOBILE SERVICE TO COME OUT AND REPLACE THEM. THE DEALER IS REFUSING TO REIMBURSING ME FOR THOSE 2 & ALSO REFUSING TO ACTIVATE THE WARRANTY SERVICE IN A TIMELY MANNER.

He said he cannot do it. The cost for this repair is $2500 in Mercedes show room. These should be recalled and repair it for free for the customers.

Hello, I have 2016 Mercedes Benz c300(W205). Recently I got a Check Engine Light with P052E71. And the solution is to replace the Crankcase Ventilation Valve/Oil Separator, Intake Manifold. These parts are positioned on the right side bottom of the engine. It was a labor intensive work which required to remove multiple parts to gain access to the oil Separator. Considering the Issue Persists from W205 and Mercedes Benz has not done anything to rectify it, the cost is actually burdened upon the customer.

This is a plug-in hybrid car and twice in the last two weeks, the car while in motion on the road, has randomly turned off the engine and lost power. The gas pedal is unresponsive and all the alarms on screen flash and I have to coast to a stop. Most recently it was on a busy road and I barely missed being rear-ended. This is an unsafe situation and has happened twice and the only thing which I can do is come to complete stop, turn off the car and restart it and the problem goes away.

While driving the check engine light came on. The inside of the car started to smell like gas. A diagnostic check was performed at the Mercedes dealership and it was determined that there were 2 faults: low boost signal & ME control unit this was due to oil leaking from the crankcase vent line through the engine wiring harness and into the ME (engine module).

When I was driving down the road my car got a message on the dash that said power steering malfunction see owners manual. My steering wheel got locked up and tight it was hard to keep control of my car at 60 miles per hour. When I took it to the repair shop, I asked about the repair and if my Vin had a recall and when I looked up the production date of my car it's 2 numbers off the Vin numbers that were recalled for your. same issue with hat happened in 2016 when my car was produced in 2015, it says the same thing. It will cost like 5k to fix the problem due to the fact that its a sensor, and when I looked up the recall it was the same sensor that the recall was on with my Vin only being 2 numbers off I find it odd that my car is not affected by this bc its the same problem of the recall the part of that controls the power steering in the car

I was just driving normally boom engine light comes on take it to the dealership and it come up as crank case vent line which they quoted me 2300$. I think this should be recalled I have seen so many people with the same issue I have actually had someone tell me this was the only major problems with the w205 c300 before this happened. I think it should be recalled because from what I’ve seen it happens to every single c300 just at different mileages. Hopefully this will get a recall because it seems to be a very common issue and should be covered by the dealer.

The small plastic located inside the sliding panoramic sunroof explode and the Panasonic sunroof can be open/close or up/down normally but when I hit close it will stop where the broken pieces was and the roof will automatically move back to the fully open position Dealer said need the rail replaced -2057800175 -2057800275 Motor is broken, need to be replaced , he said after saying the roof can go forward and backward, up and down but can’t close completely. I was gullible to believe what the technician and sale guy said. Technically technician can check the voltage and say it for sure if it is broken. Also, a technician already knew that the sliding rail is damaged. He jumped to the conclusion that motor is broken because of sunburn. I have asked my nephew what he would do in this situation. He innocently said he would replace new sliding rails first and try to run if the “alleged motor “ is really broken. If it is broken, he can just switch to a new motor before testing to confirm it working. He wouldn’t decide to buy a new motor that cost $1,400 extra while the old one might be working properly. Anyway, labor with rails and “motor” cost $3500. Then later I learn I’m not alone. How many affected from this defective parts that Mercedes doesn’t sell it separately. Owner must buy 2 set of rails- a left set and a right set. Cost $1100 total. So since the number of affected are pretty high, a few factory in China and turkey decides to produce these little and sell it online for $15-92, glue and lubricants included. -number of owners struggling to find parts https://mbworld.org/forums/c-class-w205/734208-pano-roof-failure-2.html Parts that Mercedes cannot sell it separately so owners have to buy 2 sets left set and right set rails. “Try words like repair sunroof kit for Mercedes “ on eBay only a few couple thousand people buying it in 2022 alone. https://www.ebay.com/p/28019877104 Motor broken? https://c.xtime.com/tvyUiiMwuwoA2L8JXX#/completePage

Check engine light appeared this morning, had the code scanned and found it to be P052E. This code is in reference to the Positive Crankcase Ventilation valve, which is responsible for routing excessive crankcase gases. After extensive research online, it would seem this is a known issue for Mercedes once they reach 50,000 miles, right outside of warranty. This is a very costly fix due to it being labor intensive. This should be a recall as it is a known mechanical issue, and even the dealers echo the same.

I bought the car with 51k miles . Engine failed at 71k miles , due to piston #1 cracking . Almost caused me to get rear ended on a busy street . I went to the dealership and they charged me $10250 to replace the engine with a remanned long block and they offered a 2 year warranty. 9 months, only 19k miles on “new motor” the “new” engine fails again … same reason piston # 1 cracked failed suddenly on the highway and I had to push the car to safety to the emergency lane while cars where coming.. I went back to dealer demanding a replacement and told them this is a common occurrence and they refused to help me . I called corporate. They refused to help me saying I would have to purchase an engine for the second time out of pocket when it only lasted 9 months. This is a big fault in the m274 engine … it’s also a safety hazard that can cause serious injury, fire , or even a deadly accident. I read that it’s a common issue with these engines.

The complaint is about the sunroof which has an open recall with all warning signs and risks exactly identical to my make, year and model (2016 mercedes benz c300). More than 15,000 vehicles have been affected by this problem and the warning signs suddenly appear with the vehicle. Mercedes Benz after their investigation after several reports were filed, later found that the sunroof glass panels were installed without prior application of the primer (bonding agent) which was supposed to ensure the specified strength of the bonded joint. NHTSA received several complaints concerning this issue where the sunroof suddenly began shaking and rattling which began with the driver noticing excessive wind noises in the area of the sunroof while driving indicating that the panel might be partially separated from the vehicle. I began noticing this on Tuesday May 28th, 2024, when my sunroof tilted open on the left side and failed to open properly. Upon closing it, I began to drive, and the wind noise and excessive rattling was immediately noticeable. It sounded like the wind was forcing open my sunroof and was almost like the wind was about to pull it out. In fear, I slowed down to about 20mph, but it was still very noticeable. I got scared and immediately pulled to the side of the freeway and parked. Then I immediately looked up the issue on google and noticed that there was an open recall for the exact same issue, for my make, model and year. It was noted that the roofs if not fixed will eventually pull out and flyaway posing a safety risk to the driver and other motorists who may crash as they try to avoid the debris or if the panel hits them. Luckily, I pulled over quicky out of fear for it felt like my sunroof was literally about to pull off by the wind. Now I am unable to drive my vehicle because of fear for my safety. Please I would appreciate if this were resolved and for my vehicle to be recalled and fixed immediately as soon as possible. Thanks.

The Positive Crankcase Ventilation (PCV) valve is crucial for regulating the flow of gases in the engine's crankcase. If the PCV valve malfunctions or becomes clogged in a car like the 2016 Mercedes Benz C300 4-matic, several problems can arise: 1. **Increased Pressure:** A malfunctioning PCV valve can cause pressure to build up in the crankcase. This increased pressure can lead to oil leaks, gasket failures, or even engine seals blowing out. 2. **Poor Engine Performance:** When the PCV valve fails, it can disrupt the air-fuel mixture in the engine, leading to rough idling, stalling, or decreased fuel efficiency. This can result in a loss of power and overall poor engine performance. 3. **Contamination:** A faulty PCV valve may not properly route harmful gases, like unburned fuel and moisture, out of the crankcase. This can lead to contamination of the engine oil, reducing its effectiveness in lubricating engine components and potentially causing premature wear and damage. 4. **Increased Emissions:** A malfunctioning PCV valve can result in increased emissions from the vehicle, as it may not properly recirculate harmful gases back into the combustion chamber for burning. Overall, a nonfunctional PCV valve can negatively impact both the car's performance and the environment, potentially leading to costly repairs and increased pollution. Additionally, prolonged exposure to increased emissions from the vehicle can be harmful to both the environment and the health of individuals. Therefore, it's essential to regularly inspect and maintain the PCV valve to ensure proper functioning of the vehicle.

It’s very sudden, and unpredictable. on more occasions than few, if i’m driving in the middle of a 3- lane road, and cars are stopping in the far right lane, or making a turn my break assist will malfunction and automatically break.

Mercedes-Benz comes with ECO Start/Stop feature. This feature automatically activates when you start the vehicle and have your seat belt fastened with the door closed. When this function is activated, your vehicle’s engine will shut off when you are at a complete stop, like at a stoplight or in standstill traffic. Once it’s time to start moving again, the vehicle’s engine will automatically restart as soon as you lift your foot off the brake. Randomly experiencing an issue with this feature, vehicle will not restart or it will shutdown in the middle of the road, on the busy road or freeway, it is very unsafe or dangerous. In last two years, we experienced this issue for at least 10 times, at least 5 times vehicle was towed to Mercedes Benz service center in Pleasanton, CA. They replaced the battery, starter, relay but issue still exists and service center also do not have any clue on how to resolve this issue. Reported this issue to Mercedes Benz Customer Support but response has not been favorable. I am not the only one facing this issue, several people reported this issue on online blogs, online channels and discussion boards. Mercedes Benz is ignoring the issue and not serious on addressing it. I request NTSB to investigate this issue, it is risky and dangerous. I personally had couple of close calls with other vehicles rear ending, and I am sure others must have found in this situation. Appreciate your help.

The panoramic sunroof does not properly seal to car, allowing the glass to detach and fall from the vehicle during operation and likely to impair the operator during use. Furthermore, without properly sealing the internal cabin is exposed to the environment (i.e. rain, snow, ect.) causing further damage to the internal safety and electrical features.

IN FEBRUARY 2019 THE C300 ENGINE LIGHT CAME ON, TOOK THE VEHICLE TO THE DEALER AND THEY SAID IT WAS A BAD CATALYTIC CONVERTOR, AND THE DEALER TOOK THREE DAYS TO REPAIR IT. THREE WEEKS LATER IN MARCH 2019, WHILE DRIVING 25 MILES PER HOUR STRAIGHT ON A RESIDENTIAL STREET THE CAR SHUT OFF WITHOUT A SOUND, ALL THE LIGHTS ON THE INSTRUMENT CLUSTER LIT UP, AND THE CAR COASTED TO A STOP ON THE SIDE OF THE ROAD. I TRIE TO RESTART THE CAR, THE STARTER MADE NOISE BUT THE ENGINE WOULD NOT TURN OVER. I CALLED ROADSIDE ASSISTANCE AND DID THE THREE TIME LOCK AND UNLOCK ROUTINE, AND THE CAR WOULD NOT START. AFTER TOWING THE CAR BACK TO THE SAME DEALER, THEY TOLD ME THE CAR WAS SHOWING NO CODES, THE ISSUE COULD NOT BE REPLICATED AND THE CAR SHOULD BE FINE TO DRIVE AGAIN! I'M NOW AFRAID TO DRIVE THE VEHICLE, AND THE DEALER IS REFUSING TO FIX IT.

IN ADDITION TO A STRONG, NOXIOUS, MOLDY ODOR, VEHICLE'S FRONT WINDSHIELD FOGS OVER SO TOTALLY THAT IT BECOMES DANGEROUS IN HIGHWAY DRIVING. THE HVAC/CLIMATE-CONTROL SYSTEM'S DEFROSTER IS UNABLE TO CLEAR MORE THAN THE BOTTOM FEW INCHES OF THE WINDSHIELD: THE ONLY WAY I CAN SEE THROUGH IT IS TO WIPE AWAY THE FOG WITH MY HAND. THIS HAPPENS WHEN THE VEHICLE IS IN MOTION BUT PERSISTS WHEN IT IS STATIONARY. THIS HAPPENS IN ALMOST ANY WEATHER, BUT ESPECIALLY IF THERE IS MOISTURE IN THE AIR(FOG, RAIN).

AFTER STOPPING AND WAITING AT A TRAFFIC LIGHT FOR 15-30 SECONDS, I HAD MY FEET ON THE BRAKES AND LEFT TURN INDICATOR ON. THE "HOLD" OPTION TO LOCK MY BRAKES WAS NOT ENGAGED. THE CAR WAS STATIONARY. WITHOUT WARNING, THE CAR SHIFTED INTO DRIVE AND JOLTED FORWARD INTO THE VEHICLE AHEAD OF ME AT THE LIGHT. (I WAS THE SECOND CAR IN LINE, AND I STOPPED ABOUT A HALF CAR LENGTH BEHIND THE OTHER DRIVER.) THE ACCELERATION WAS NOT A TYPICAL, GRADUAL MOVEMENT ASSOCIATED WITH WHAT HAPPENS WHEN I RELEASE MY FOOT FROM THE BRAKE TO DRIVE. IT WAS A SUDDEN AND JARRING JUMP REGARDLESS OF THE FACT THAT MY FOOT NEVER LEFT THE BRAKE. I TRIED TO PRESS THE BRAKES MULTIPLE TIMES TO STOP THE FORWARD MOVEMENT, BUT MY CAR HIT THE VEHICLE IN FRONT OF ME TWICE. THE STEEL BUMPER OF THE OTHER VEHICLE WAS NOT DAMAGED. THE FRONT AREA OF MY HOOD (EMBLEM AND GRILL) WERE CRUSHED. I REPORTED EARLIER ELECTRONIC ISSUES TO MY LOCAL DEALERSHIP AS NOTABLE ODDITIES, BUT NONE MADE ME THIS CONCERNED ABOUT SAFETY OF OTHERS, MY PASSENGERS, AND MYSELF. AS RECENTLY AS A WEEK EARLIER, MY REAR-VIEW CAMERA FROZE AND LOCKED AS I WAS REVERSING INTO MY GARAGE, SO HAD I TRUSTED THE SCREEN IN MY CAR, I WOULD HAVE REVERSED ANOTHER 5-10 FEET INTO MY GARAGE. I COULD NOT UNFREEZE IT WITHOUT PUTTING THE CAR BACK INTO DRIVE AND RESTARTING MY CAR. MONTHS EARLIER, THE SENSOR ON MY SIDE MIRRORS STARTED TO GO OFF WITHOUT ANY OTHER SOURCE OF DANGER OR COLLISION ON VACANT STREETS. THE AIR PRESSURE ALERT WARNED THAT MY TIRES WERE BECOMING DANGEROUSLY FLAT; HOWEVER, EN ROUTE TO THE GAS STATION, THE PRESSURE MONITOR NOTED THAT ALL TIRES WERE NOW RETURNING TO NORMAL PRESSURE LEVELS AND NO INFLATION WAS NEEDED. THERE HAVE BEEN MANY PECULIAR EVENTS WITH THIS NEW C300 IN RECENT MONTHS, BUT MY PRIMARY CONCERN AS A CAREGIVER IS THE SUDDEN ACCELERATION FROM A STOPPED POSITION--OR FROM ANY POSITION--WITHOUT MY DIRECTION OR INTENT.

SINCE THE PURCHASE OF OUR 2016 MERCEDES IN DECEMBER OF 2015, WE HAVE BEEN EXPERIENCING THE WARNING DISPLAY OF THE TIRE PRESSURE ON NUMEROUS OCCASIONS. THE FIRST OCCURRENCE PRIOR TO TAKING IT TO A DEALERSHIP MY WIFE TOOK IT A LOCAL TIRE SHOP WHERE THE OWNER PUT AIR IN THE TIRES AND THE LIGHT WENT OFF. IT OCCURRED SEVERAL MORE TIMES AND I ALWAYS WENT TO LOCAL GAS STATIONS AND PUT AIR IN. AFTER GETTING FRUSTRATED WE DROVE TO THE DEALERSHIP IN VALENCIA CALIFORNIA SHOWED THE SERVICE ATTENDANT THE ALERT ON THE DASH. HE RETRIEVED AN AIR PUMP AND PUT AIR IN ALL THE TIRES ACCORDING TO THE SPECS AND SENT US ON OUR WAY WITHOUT DISCUSSING THE WARNING ALERT WHICH WENT OFF. AFTER APPX A WEEK AND A HALF OF DRIVING WE RETURNED WITH THE SAME PROBLEM.. MY WIFE SPENT 4 HOURS WAITING AND ACCORDING TO THE SERVICE RECEIPT THEY SAID THE TIRES WERE ROTATED AT THE CLIENT'S REQUEST AND NEVER MENTIONED THE ALERT ON THE DASH BEING REPORTED BY THE OWNER. WE HAVE TAKEN IT A COUPLE OF MORE TIMES ONE OF WHICH THE CHECKED AND SUBMERGED ALL THE TIRES TO CHECK FOR LEAKS AND RIM DAMAGE WHICH THEY ALL CHECK OUT PROBLEM FREE. AND AS USUAL THE ALERT CAME BACK ON AFTER APPX. A WEEK AND A HALF OF DRIVING. TODAY THE ALERT IS BACK ON WITH ANOTHER RED WARNING SIGN AND WE ARE GOING TO DRIVE IT BACK TO THE DEALERSHIP IN VALENCIA TOMORROW SINCE THEY WILL NOT SEND A TOW SERVICE OUT WHEN THE OWNER'S MANUAL CLEARLY STATES "IN DANGER OF AN ACCIDENT PULL OVER AND DO NOT DRIVE". THIS IS THE SECOND RED LIGHT WARNING ON THE VEHICLE AND IT APPEARS THEY HAVE NO IDEA WHAT THE PROBLEM IS. ON THE FIRST OCCASION WHEN THE RED LIGHT CAME ON WE WERE INSTRUCTED TO DRIVE THE VEHICLE IN REGARDLESS OF THE RED LIGHT WARNING. I CONTACTED THE MERCEDES BENZ USA COMPLAINT DEPARTMENT THIS MORNING AND FILED A COMPLAINT. THE DEPT OF CONSUMER AFFAIRS INSTRUCTED ME TO FOLLOW THE ARBITRATION GUIDELINES IN THE BACK OF THE MANUAL.
