My clock spring is no longer working, it made all the buttons on my steering wheel stop working and i am afraid the airbag will deploy at random since there was a recall on cla models 2015-2018. I own a Mercedes cla 250 2018 but it is not showing a recall on my specific vehicle. Not only that but they no longer sell just the clock spring for my car, im assuming because of the recall. I am scared that my airbag will randomly deploy while im driving or that it will not deploy at all in case of an accident. It was diagnosed by an independent mechanic There was no other messages except when my left side airbag service needed message popped up

Air says it will malfunction nothing has happened but wish for it to be repaired before an accident

Sep 02, 2024

The year and model of my car has been recalled for a steering column module/clock spring. Mercedes says my VIN is not in the recall. This is a safety concern as an airbag will not deploy. I believe I should be included in the recall.

I have sent the below email over 100 times to Mercedes To whom it may concern, I am writing regarding the purchase of a CLA250 4matic in December. I had a 120 point inspection done that did not show any issues with this car. As I was driving down a dark road around 1 am, my life was thrown in danger as the command shaft shut off and I could not see the dashboard or any lights in the vehicle. I was alone and on a dark road. After sitting for 15 minutes, I was able to get a light to come on and drove to my destination. On my way home, the lights were acting erratic and the brake lights, bright lights, engine lights, gas gauge, rpm gauge and caution lights were flickering the entire time. The car had no problems starting, however this continued to happen. I parked the car for several days and after starting it again, the dashboard was black, I could not see to put it in park. I tried several days later and got the lights to come on and after driving through the light, the parking brake was thrown in place as I was driving, almost ejecting me from this vehicle. I immediately turned around and parked the car for over a week until bringing it to your service location at Atlanta South. The car put my life in danger, almost ejecting me out of the car. Thankfully I was not on the highway driving higher speeds or I would have been killed.. I am asking for Mercedes Benz to cover the entire amount for the command which I was told during service check was defective and wiring issues within the command. The cost is over 2,900. I believe this is a manufacturing defect whether you have any recalls on it or not. I will file a safety recall complaint with the NHTSA Nation vehicle recall for these vehicles of this make and model advising that you could be killed while driving this car without further recall. I have had other Mercedes benz vehicles and never had this problem. This is a matter of life or death. The car is currently parked at the dealer after inspection.

The panoramic sunroof opens and closes but will not shut completely in the back. When calling around for a quote mechanics were aware of the issue occurring with this specific make model and class of vehicle.

Jul 28, 2025

The cluster panel lights that indicate speed, fuel, brakes, lights, turn signal, engine light, high beams and all other components of safety of car continue to black out altogether or flash on and off continuous while driving. Safety is an issue if your driving and cluster panel blacks out. You do not know the speed your driving at and no turn signals work. The problem was reported to Mercedes and the software was reset. The problem continues to happen while driving and is dangerous on highways as speedometer and turn signals do not work. Gas gage spins from full to empty and brake and engine lights flash on and off or cluster again goes black. There are or have never been warnings. While driving it just happens. This has been happening on and off for a few months. Mercedes does not know the cause.

Jan 09, 2024

I WAS DRIVING ON THE ACCESS ROAD GETTING READY TO MERGE ONTO THE HIGHWAY. I PROCEEDED ONTO THE HIGHWAY AND MADE IT INTO THE MIDDLE LANE GOING AROUND 60 MPH BUT SHORTLY AFTER MY CAR THREW ITSELF INTO NEUTRAL AND THE DASH LIT UP WITH THREE LINES OF WORDS: THE FIRST LINE SAID 'SERVICE REQUIRED', THE SECOND LINE SAID 'DO NOT SHIFT GEARS' AND THE LAST LINE SAID 'CONTACT DEALER'. I WAS ABLE TO PULL MY CAR OVER TO THE FAR LEFT HAND SIDE OF TRAFFIC. I TURNED OFF MY CAR AND TURNED IT BACK ON AND IT STARTED WITH NO ISSUES. SINCE THIS INCIDENT THOUGH, I HAVE HAD OTHER ELECTRICAL ISSUES THAT HAVE FOLLOWED.

When you start off at a slow speed, the rear end of the car starts making a knocking noise. We had it inspected by Mercedes-Benz and they said that it is the rear differential.

Jun 25, 2025

SOS e call not activated and I’ve called Mercedes numerous times. They can’t get the car to respond they say it’s a communication error on their end however the dealership wants to charge me $300+ to update the software when it’s their issue. Also 2 months before I purchased this car I noticed not only was this one of the recall issues that the dealership supposedly fixed. But from the beginning this vehicle has had nothing but issues. I shouldn’t have to pay out of my pocket for the manufacturer. I had received a complementary 3 months of the mbrace that I didn’t even get to fully use before the sos stopped working

Jan 29, 2023

Manufacturer has not fixed the outstanding software safety recall in a timely fashion. I have contacted them over 10 times and no one has any idea when the software update will be sent and there is no one they can escalate the issue to. I use the car for work, but I am not allowed to use a car with an outstanding safety recall.

Aug 02, 2021

WE WERE ADVISED MERCEDES-BENZ IS ISSUING A RECALL DUE TO MOLD EXISTING IN THE FACTORY HVAC SYSTEM FROM A LAW FIRM MAILER. WHEN CONTACTING MERCEDES-BENZ, THEY STATED THEY ARE OF THE PROBLEM AND TOLD US A RECALL WOULD BE TAKING PLACE AROUND JANUARY 2021. WE BOUGHT THIS VEHICLE NEW IN OCTOBER 2018 AND INGEST POSSIBLE MOLD SPORES DAILY WHILE ENDURING A HORRIBLE MUSTY SMELL. WE ATTEMPTED TO TRADE IN OUR VEHICLE FOR A NEWER MODEL AND WERE INSULTED WITH THE SALES MANAGER'S RESULTS AT ZT MOTORS, FORT WALTON BEACH, FL. SO, NOW WE ARE STUCK WITH A $70,000 VEHICLE, PAYING MONTHLY PAYMENTS, AND NOT BEING INFORMED DIRECTLY BY MERCEDES WHEN THIS CORRECTION WILL TAKE PLACE. I HAVE AN AUTOIMMUNE DISORDER AND BEING AROUND MOLD IS EXTREMELY DANGEROUS FOR ME. VERY DISGUSTED BY MERCEDES-BENZ AND WILL NEVER PURCHASE ANOTHER AS THEY DO NOT TAKE CARE OF THEIR LOYAL CUSTOMERS.

Within 2 weeks after purchasing this vehicle the front stationary roof panel flew off the car. I noticed it when I parked at work in the parking lot. I do not know where the panel is. I retraced my route and did not see it anywhere. I work less than 2 miles from work with no turns. I am very concerned that the panel may cause water damage/leaking and even be a danger / damage to another drivers safety. I went to MB they said that there was no recall. They said that I should file claim to repair it. Claim and repair done be MB. NOW the same thing happened again. The panel has flown off again while I was driving on the highway around 3:00pm the panel nowhere to be found. MB said file a claim. 2 repair companies said the glue /sealant could be the issue. There were no notifications that this would happen. Pictures have been taken for both incidents. Upon referencing Vehicle Compliance & Analysis there is a recall Campaign Description: 23P2197658 NHTSA ID 23V854 I am having a difficult time getting my vehicle repaired without having to file another claim or paying for it myself.

The contact owns a 2018 Mercedes-Benz CLA250. The contact stated that while the vehicle was at the car wash, water entered through the overhead center console.

The manufacturer was made aware of the failure but informed the contact that there was no recall associated with the VIN. The failure mileage was approximately 61,050.

roof front panel coating peeling off - there has been a recall for this issue on most mercedes benz of my year - not just my model- seems to consistently be an issue for the front panel between windshield and sunroof- https://static.nhtsa.gov/odi/rcl/2021/RCMN-21V197-6244.pdf my specific VIN wasnt included in the recall but i am having the exact same issue- Mercedes told me to reach out to NHTSA to see about getting my VIN batch included in recall or re-issue broader recall to include my VIN # - they will not replace otherwise - so many people online have same issue as me and obviously it was enough of a hazard that the first recall was issued but there are more cars affected by it than what was covered.

POWER TRAIN

My 2018 Mercedes-Benz CLA250 4MATIC is experiencing a knocking noise from the rear differential at low speeds. The issue poses potential driving hazards, including possible loss of control and increased wear on drivetrain components. The noise may indicate a failing differential, which could suddenly fail while driving. I have contacted the dealer, but no specific recalls or factory service announcements have been identified for this problem. This appears to be a common issue reported by other owners. At the recommendation of the service technician, I replaced the rear solenoid, at the cost of $400, but no improvement. A rebuild of the rear differential was the recommendation.

Sep 05, 2024

2018 CLA250 30k miles, leaving the airport the car suddenly felt as if it lost power and slowed un-commanded. It then began to operate normally for the 50+ mph drive home. Upon reaching my neighborhood, the car began to make a clunking, popping sound when under load less than 30 mph. The days after the vehicle continued to experience the same issues every time it was driven. I took the car to a local trusted mechanic and he said it’s the rear differential and most likely failed pre-maturely and it’s not work he can do. He said a rear differential failing with 30k miles would be extremely rare and recommend I reach out to the manufacturer to have it replaced and to keep him updated as to how Mercedes handles this. After taking it to Mercedes of Bellevue the service adviser said this is common on CLAs and GLAs since 2014. Even to the point saying he has a GLA and hasn’t had the issue yet luckily. After speaking to the service manager at Mercedes of Bellevue and asking him directly if he has ever heard of a rear differential failing with less than 30,000 miles on the car he said “no”. After bringing my car in the service advisor said “yes, he has have seen a lot fail to the point i worry about it” as he has the same rear differential in his car. My car is 10 months out of time warranty but 20,000 miles under the mileage warranty. Looking online on the CLA250 owners forum this does seem to be a common issue on CLAs, GLAs and other models that use this rear differential.

My car randomly caught on fire, it was parked in my apartment garage for a week while I was out of town. I came back to use my car and my car remote wasn’t unlocking the car so i unlocked it manually. When I opened the car it wreaked of smoke, the windows were covered in soot, the visors were bubbled up, the passenger seat had a chunk missing. It was investigated by a car shop for My insurance and the car shop Said they felt like the fire started from the wires under the passenger seat. Of course it was deemed a total loss and now I’m out of car. I hadn’t even had the car a year.

I am driving around 55K miles in this car, and my check engine light comes up. I head to a local place to get a code check. The guy looks it up and tells me this is pretty much with EVERY Mercedes CLA around that mile point.. So, I look up on reddit and other forums, and it's exactly what he said. Pretty much the PCV valve is faulty and costs around $1800-2500 to fix after 50-60K miles which causes emission problems and other safety concerns if not taken care of. It makes no sense how this is not a recall. Of what I read, Mercedes knows all about this and has done nothing, just leaving the drivers to take care of a problem that they did nothing to cause. I am not sure if this is for the NHTSA or what, but it is kind of unacceptable.

Vehicle cluster lights go black while driving...dangerous due to no fuel gauge..no speed gauge... no speedometor..no seat belt warning and no blinkers to exit highway safely....there is a danger of crashing as vehicles goes hesitant during black periods...this is an ongoing problem with Mercedes as documented for numerous years with numerous vehicle's and different models. The safety of my driving this vehicle has come down to your ethics.. Does Mercedes value their customer [I think not] or does the safety of Highway Patrol ignore this dangerous and catastrophe accident waiting to happen.? I really hope someone will be helpful and I do really appreciate your time to this issue...

Regarding 2018 CLA 45 AMG: On 9-21-21, while I was driving approximately 45 MPH on a 4 lane road, suddenly the car completely shut down. A message simultaneously popped up that the car was disabled and instructed me to look up in manual. Immediately I turned right into the first driveway where the car came to a stop. I was able to restart car and drive home. At that point, the car's total mileage was 17,189. 10-7-21: Deeming the car unsafe to drive, I had the car towed to Mercedes-Benz of Raleigh for a pre-arranged appointment on 10-8-21with service advisor Christopher Moore. After the tech ran numerous tests, he found the ME control unit was faulty and replaced it at no charge. Since I drove it back home, I haven't driven it since.
