TAKATA RECALL SINCE JANUARY 2018 I HAVE BEEN WAITING FOR THE REPLACEMENT PARTS TO ARRIVE FOR THIS RECALL. I HAVE MOVED TO CANADA AND IN ORDER TO TRANSFER MY VEHICLE THERE CAN BE NO OUTSTANDING RECALLS. I HAVE BEEN CONTACTING MERCEDES FOR OVER A YEAR YET THEY ARE UNABLE TO PROVIDE ANY ANSWERS AS TO WHEN THE REPAIR WILL BE DONE. THIS RECALL HAS BEEN OUTSTANDING FOR FAR TOO LONG AND IS PREVENTING ME FROM TRANSFERRING MY VEHICLE.
Jun 10, 2019
TAKATA RECALL. RECALL WAS ISSUED IN FEBRUARY 2016 AND I'M STILL WAITING FOR THE AIRBAG TO BE FIXED. MERCEDES BENZ HAS FAILED TO REMEDY MY CAR IN A TIMELY MANNER AND THEY HAVE NOT OFFERED ANY ALTERNATIVE SOLUTION, RENTAL CAR OR LOANER CAR WHILE I WAIT. IT HAS BEEN 39 MONTHS SINCE THE RECALL WAS ISSUED AND THERE IS NO INDICATION FROM MERCEDES WHEN THIS WILL BE FIXED.
May 18, 2019
THE TAKATA AIRBAG RECALL DEFECT HAS NOT BEEN REPAIRED ON OUR MERCEDEZ FOR OVER 3 YEARS NOW. WE HAVE NOT BEEN ABLE TO RESELL IT DUE TO THE RECALL, VALUATION HAS DECREASED AS WELL DUE TO THE REPAIR NOT BEING PERFORMED BY THE DEALER. SHOULD THIS HAVE BEEN DONE IN A TIMELY MANNER? IT CLEARLY WAS NOT.

SUSPENSION
6 complaints
4-5 MILES INTO DRIVING AIRMATIC MALFUNCTION APPEARS ON MY DASHBOARD ( PICTURE OF AN STRAIGHT UP ARROW IN THE MIDDLE OF CAR PICTURE) WHEN I INCREASE THE SPEED TO 50 MILES THE TACHOMETER GOES CRAZY AND I HEAR LOUD SOUND. CAR HAS LESS THAN 50 000 MILES.
Oct 06, 2018
AT AROUND 60K MILES, I HAD TO REPLACE THE AUTOMATIC SUSPENSION ON BOTH OF THE FRONT TIRES (AROUND $3,000). NOW I'M HAVING ISSUES WITH THE BACK AND WILL PROBABLY HAVE TO REPLACE THEM AS WELL AT 69K MILES.
Aug 30, 2018
CAR JUST REACHED 90K MILES WITH LIMITED DRIVING. THE AIRMATIC SUSPENSION HAS BEEN ACTING ODDLY FOR THE PAST MONTH - I WOULD FIND IT LOW IN THE REAR IN THE MORNING AFTER BEING PARKED IN A FLAT GARAGE. THE NEXT DAY THE ENTIRE CAR WOULD BE LOWERED. WHE IS TURN OFF THE CAR, YOU WOULD HEAR AIR BEING RELEASED. TODAY, WHEN PARKED, THERE WAS A LOUD EXPLOSION, THE CAR SHOOK FOR A FEW MINUTES AND THEN THE ENTIRE THING SANK TO THE WHEEL WELLS. ASSUME THE COMPRESSOR HAS EXPLODED AND AFTER READING VARIOUS POSTS, THIS IS A COMMON PROBLEM WITH ALL MERCEDES THAT HAVE AIRMATIC SUSPENSIONS AND SHOULD BE FIXED/RECALLED BY MERCEDES.
Jul 25, 2018
WHILE DRIVING THE BALANCING INDICATOR LIGHT CAME ON. THEN THERE WAS A LOUD BANG AND THE VEHICLE SHOOK VIOLENTLY. IT FELT LIKE I WAS REAR ENDED. THEN WAS VEHICLE WAS SITTING ON THE SPRINGS. MY VEHICLE HAS ONLY 83000 MILES ON IT AND I HAVE HAD TO REPLACE THE FRONT AND NOW REAR SUSPENSION.
Jan 12, 2018
AT 80K MILES THE FRONT AIR SUSPENSION STARTED LEAKING AND I HAD THEM REPLACED AT A COST $2414.42. I WAS ALWAYS WORRIED THAT NEXT WAS THE BACK SUSPENSION AND THIS IS NOW TRUE THAT I HAVE TO DO THE SAME FOR THE REAR AIR SUSPENSION AND I CAN ESTIMATE BASED ON THE LAST REPAIR PRICE THAT PERHAPS WILL BE PAYING ANOTHER $2500. I HAVE SPOKEN TO VARIOUS PEOPLE WITH THE SAME TYPE OF CARS WHOM I MET WITH FLATTENED AIR SUSPENSIONS AND DID NOT KNOW WHY THEIR CAR SUSPENSIONS WERE LEAKING. AT LEAST IT WOULD BE GOOD IF MERCEDES COULD PROVIDE US WITH METAL ALTERNATIVES BECAUSE DO THINK IN THE NEXT 2 TO 3 YEARS, I WILL BE REPLACING THEM AGAIN AND AGAIN. PLEASE HELP, THIS DOES NOT SEEM RIGHT OR EVEN FAIR TO HAVE LEAKING SUSPENSION.

HELLO, I WOULD LIKE TO NOTIFY A DEFECT ON A VEHICLE MERCEDES GL 500 MODEL SERIES X166 MADE IN 2012 IN U.S. PLANT BY MERCEDES COMPANY IN SEATTLE. WHILE DRIVING THERE WAS A FAULT IN THE BRAKING SYSTEM WITHOUT ANY WARNING LIGHTS. DURING THE BRAKING THE BRAKE WAS PUSHED TO THE FLOOR, BUT THE VEHICLE WAS NOT STOPPING. IN THE CASE IF THE VEHICLE WAS DRIVEN BY AN INEXPERIENCED DRIVER, IT IS MORE THAN CERTAIN THERE WOULD HAVE BEEN AN ACCIDENT. THE VEHICLE IS CURRENTLY LOCATED AT AN AUTHORIZED MERCEDES SERVICE IN TRENCIN (SLOVAKIA) AND HEADQUARTERS COMPANY DOES NOT APPEAR INTERESTED IN RESOLVING THIS SERIOUS SECURITY DEFECT. THEREFORE, THE VEHICLE WAS MANUFACTURED IN AMERICA AND MOSTLY IS SOLD IN THE U.S. MARKET; I GIVE THIS FACT TO YOUR ATTENTION WITH THE RECOMMENDATION TO INVESTIGATE THE TECHNICAL CONDITION OF THESE VEHICLES.

Mercedes Benz settled with U.S Government the diesel emission scandal. There are about 122k class members. Under the settlement, Mercedes gave 122k class members 4 year/48k miles warranty. Under the warranty, MB replaced the timing chain in May 2022 but on April, 2023 while driving on I-95 in Massachusetts, the engine completely got shut down while driving 55 miles per hour. Luckily, no one got injured. But the car was not controllable. I barely pulled to the side of the hwy and called the towing. Brought it to MB of Westwood. MB Westwood did a diagnostics.Below is the note Mercedes Benz of Westwood: The car is still at the dealership if you want to send an investigator, Engine Rebuild/Replace: after further tear down found that timing chain guide rails broke, which then got chewed up from chain and gears into smaller pieces. these small pieces got suck up into the oil pump pick up tube, blocking oil flow. The lack of oil to main engine components caused them to overheat and contacted each other (metal to metal). which ends up heating to a point in which the components stick to each other and not able to move freely any more.. Basically, The replaced Timing Chain destroyed plastic guide rails, which destroyed my engine. I notified Mercedes Benz of USA and the dealership that they need to recall 122k class members and fix the problem, but they refused to take any actions. By ignoring the problem, it could lead to casualties to thousand of people. I hope you take actions and bring Mercedes Benz USA accountable and they start recalling and fixing the problem before its too late.

SERVICE BRAKES

Breaks became unusable due to lost power break fluid caused by corrosion on the lines. Fluid was completely gone and breaks were not effective at all. Dashboard showed RED light with break error. Dealer confirmed that rust build up caused the failure.
Jan 19, 2023
This is relative to the brake booster recall. Mercedes-Benz conducted a test and there was significant corrosion that exceeded the normal limits allowed. I am still under a stop drive order but I have not been provided any further instruction or provided a vehicle to drive while my vehicle awaits repair or buy back.Customer service representatives have not corresponded with me despite multiple emails and calls over the last 2 -3 weeks. I need A vehicle repaired so it can operate safely or I need another vehicle to drive while awaiting available parts please.
Aug 03, 2022
I HAVE BEEN ISSUED A STOP DRIVE ORDER UNDER RECALL ID# 22V315. I HAVE CONTACTED MERCEDES BENZ TWICE AND BEEN IGNORED TWICE. FIRST CALL WAS AROUND JULY 5TH-2022 AND SECOND CALL WAS ON JULY 12TH. THEY APPARENTLY DO NOT CARE ABOUT YOUR STOP DRIVE NOTICE AS NO ONE HAS GOTTEN BACK TO ME ON THIS ISSUE.

"TAKATA RECALL" MY 2012 GL 450 MERCEDES BENZ ABS WARNING LIGHT CAME ON WHILE DRIVING IN THE CITY. WHILE DRIVING AT ABOUT 45 MILES PER HOUR THE BRAKES ENGAGED BEFORE I COULD STOP MY VEHICLE AND PULL OVER. IT LITERALLY ALMOST SENT ME THROUGH THE WINDSHIELD, A HARD GRINDING SOUND AND AN INTENSE STOP. STILL TRYING TO GET OUT OF THE WAY OF TRAFFIC THE VEHICLE JERKED AND JERKED AND THE BRAKES CONTINUED TO ENGAGE. THIS WAS VERY DANGEROUS AND COULD HAVE CAUSED A SERIOUS ACCIDENT. THIS IS VERY DANGEROUS. IF THE ABS SYSTEM IS FAULTY OR A BAD SENSOR THEN IT SHOULD NOT ENGAGE ITSELF AT ALL. I CALLED THE LOCAL MERCEDES DEALER AND SPOKE WITH A SPECIALIST AND HE INFORMED ME THAT YES THE BRAKES WILL ENGAGE IF THERE IS AN ISSUE WITH THE ABS. AGAIN THIS IS VERY DANGEROUS AND A RECALL SHOULD BE ON THE SENSORS WHETHER IT'S THE ABS SENSORS OR THE SPEED SENSOR WHICH THEY ALSO INFORMED US THAT COULD CAUSE THIS MALFUNCTION. REGARDLESS THE VEHICLE BRAKES SHOULD NOT ENGAGE WHILE DRIVING.

AFTER PURCHASING THE VEHICLE USED FROM A DEALER (WITH @ 36,000 MILES) I STARTED HAVING TRANSMISSION PROBLEMS WITHIN A YEAR. WHEN I WOULD BE STOPPED ON A HILL/INCLINE AND THEN ACCELERATE THE CAR WOULD VIOLENTLY JERK (AS IF I HAD HIT SOMETHING). IT WOULD NOT GO FORWARD UNTIL AFTER THE SUDDEN JERKING MOTION STOPPED. IT WOULD ALSO BEHAVE THIS WAY WHEN I BACKED UP A HILL OR INCLINE. EVERY YEAR I BROUGHT IT TO THE DEALER TO DIAGNOSE AND FIX IT AND THEY TOLD ME THAT THEY COULDN'T REPRODUCE IT WHEN THEY HAD THE CAR, THEREFORE THEY COULDN'T FIND OUT THE PROBLEM. I ALSO TOLD THEM THAT THE ENGINE LIGHT WOULD COME ON AND OFF INTERMITTENTLY, HOWEVER, THEY WERE UNABLE TO FIGURE OUT THE PROBLEM. EVERY TIME I TOOK IT IN FOR A SERVICE THEY DOCUMENTED THE PROBLEM ON THE ESTIMATE SHEET. HOWEVER, THIS LAST TIME I BROUGHT IT IN THEY WERE ABLE TO DIAGNOSE THE PROBLEM AS A FAULTY TRANSMISSION. IT WOULD SLIP OUT OF GEAR WHEN ON A HILL OR SLIGHT INCLINE WHEN PUT INTO DRIVE OR REVERS FROM A COMPLETE STOP. COME TO FIND OUT WHEN RESEARCHING THESE CARS THAT MERCEDES HAVE HAD THIS PROBLEM WITH THEIR ENGINES FOR A LONG TIME.

ON JANUARY 8, 2014, THE OWNER OF THE 2012 MERCEDES BENZ GL450 WAS INSIDE HER VEHICLE WITHIN THE GARAGE OF HER RESIDENCE, PREPARING TO LEAVE TO PERFORM ERRANDS. REALIZING SHE NEED TO ATTEND TO HER YOUNG CHILDREN, SHE PUT THE VEHICLE'S ELECTRONIC TRANSMISSION INTO PARK AND WAS EXITING THE VEHICLE WHEN THE GL450 SUDDENLY BEGAN MOVING REARWARD IN REVERSE. THE REVERSING VEHICLE PINNED THE OWNER BETWEEN THE OPEN DRIVER'S DOOR AND THE GARAGE WALL, IMPACTING THE LEFT SIDE OF HER BODY WITH ENOUGH FORCE TO FRACTURE HER PELVIS AND BEND BACK THE HINGES OF THE DRIVER'S SIDE DOOR (SEE ATTACHED PHOTOGRAPH. THE VEHICLE THEN CAREENED OUT OF THE GARAGE WITH HER TWO SMALL CHILDREN INSIDE THE RUNAWAY DRIVERLESS VEHICLE. FEARING FOR THE SAFETY OF HER YOUNG CHILDREN WHO WERE STILL IN THE GL450, THE SEVERELY INJURED OWNER RAN DOWN THE DRIVEWAY TOWARD THE VEHICLE AND REACHED IT JUST BEFORE IT CRASHED INTO A GATE. PLEASE SEE ATTACHED DOCUMENT FOR DETAILS.

ON 01/08/14, A FEMALE DRIVER OF A 2012 GL 450 WAS STATIONARY, IN THE GARAGE, WITH ENGINE RUNNING. BEFORE SHE EXITED THE VEHICLE TO CHECK ON HER CHILD IN THE REAR OF THE VEHICLE, SHE PRESSED THE PARK BUTTON ON THE DRIVE SELECT ELECTRONICALLY-CONTROLLED COLUMN SHIFTER. AS SHE EXITED AND WALKED AROUND TO HER CHILD, THE TRANSMISSION SUDDENLY SHIFTED INTO REVERSE, THE VEHICLE TRAVELLED BACKWARDS AND PINNED HER BETWEEN THE OPEN DRIVER'S DOOR AND THE GARAGE WALL. LUCKILY, THE VEHICLE'S DOOR HINGE BOLTS BROKE, THE DOOR FOLDED AND SHE WAS ABLE TO EXTRICATE HERSELF, AS THE VEHICLE CONTINUED TO TRAVEL IN REVERSE UNTIL IT WAS STOPPED BY A COLUMN AT THE END OF THE DRIVEWAY. THE DRIVER SUSTAINED MASSIVE DEBILITATING INJURIES. WE BELIEVE THAT BECAUSE OF AT LEAST TWO SERIOUS ENGINEERING MISTAKES AND/OR DEFECTS, THE MERCEDES GL 450 DRIVE SELECT ELECTRONICALLY-CONTROLLED COLUMN SHIFTER FAILED TO ENGAGE INTO PARK. ## VIN PASSED ## MERCEDES-BENZ GL450 2012 ##

Recently discovered that water intrusion in the back of my vehicle is coming from cracks (longitudinal and transverse) on its roof. The roof has no other damage that would have caused the cracks Upon discovery, I took it to my local MB dealership and the attendant that looked at it said he had never seen such cracks and know the cause. I followed up with the Mercedes Benz corporation, who requested for my VIN, and following review of my complaint told me that there was no recall affecting roof cracks for my vehicle. They suggested that I reach out to you (NHTSA online). I am not sure when these cracks developed. I was aware of it earlier this year. The water intrusion, when not dried and depending on what time of the year, could cause mold which can seriously affect the occupants of the vehicle. It would be appreciated if you take a look at this, as well as if there are similar complaints on this GL450 models

SEAT BELTS
2 complaints
While I was driving the car, with the seat belt fastened, the seat belt suddenly popped out. This was a scary experience! Repeated attempts to fasten the seat belt again did not work. On closer inspection, it appears that something inside the fastening system was probably broken, and the seat belt wasn't getting fastened in there. I immediately took the car to the dealer (Mercedes Benz of El Dorado Hills). After inspecting it, they were able to reproduce the issue (seat belt not getting fastened at all) and advised replacing the seatbelt system on the car. Unfortunately, they did not have the part in stock, so they advised that they would order the part and charge me $800 for this. I can't believe that a fundamental car safety system like this would fail like this. Imagine if there was a car accident and the seat belt just popped out of the fastener, not doing the job it was designed for? Thank you for investigating this issue. It could indeed save a lot of lives, if this is a widespread issue, necessitating a recall campaign from Mercedes.

I would like to file an official complaint with Mercedes Service center prior to escalating. Due to neglection the part of your authorized dealership, I am confronted with poor and conniving customer service, strong safety concerns, and financial loss. Also, Euro Motors did not report any issues with the vehicle wire harness during the pre inspection. During the pre inspection the only thing Mechanic pointed out was the rear left air suspension bag losing air (see attached videos of pre and post inspection).I brought in my GL350 for the manufacturing recall on September 20th, with sufficient time to file for the $878.75 cash back rebate for Class Action Settlement. Euro Motors of Germantown, deliberately or carelessly kept my vehicle past the due date of the rebate. When I received the vehicle almost a month later, it stalled in the middle of the highway, risking my life as it gave no prior indication of stalling. When I opened the hood to inspect the vehicle, I noticed the harness wires were tampered with. I have actual evidence of the engine prior and post Euro Motors maintenance, which I will make available if necessary. I have lost my trust with this dealership performing and further work, and I would like Mercedes to take further action to ensure my trust in their brand. I can be available for direct discussion with contact information below. On 20th October 2022, I received my car back from the dealer. I was told their mechanic performed all safety inspection and the car is roadworthy. After I inspected my vehicle I found Euro Motorcars Mercedes-Benz Germantown location left a leaking fuel line and return the car back to me. I would like NHTSA to investigate this safety issue.

TAKATA RECALL - I HAD HEAD-ON COLLISION ACCIDENT ON 02/03/2015, STEERING WHEEL AND LEG AIR BAG WAS DEPLOYED, BUT CAUSED ME INJURY AFTER IT DEPLOYED TO MY HAND, FINGERS AND KNEES. ONCE LEG AIR BAD DEPLOYED, MY RIGHT KNEED HIT THE SWITCH UNDERNEATH THE DRIVER SEAT AND CAUSED INJURY. MERCEDES DON'T INSTALL THIS SWITCH UNDERNEATH THE SEAT ANYMORE AND I BELIEVE THERE WAS FLAW IN DESIGN AND LOCATION OF THIS SWITCH AND NOW THEY CHANGED THE LOCATION OF SWITCH. THEY MIGHT HAVE FOUND SOMETHING IN THEIR TESTING. PLEASE SEE PICTURES OF MY INJURIES ON FINGERS CAUSED BY STEERING WHEEL AIRBAG AND KNEE INJURY BY LEG AIR BAD HITTING THE SWITCH. I HAVE MORE PICTURES OF ACCIDENT SCENE AND WOULD LIKE TO SHARE. AROUND 8:05 AM I LEFT MY HOME TO GO TO WORK. WHEN I WAS ON BRIDGE NEAR THE FIRE STATION, I SAW SILVER CAR CAME IN MY LANE AND DRIVING TOWARDS ME. I CAME IN MY MIND THAT THIS CAR IS GOING TO HIT ME AND AS IT WAS COMING CLOSER AND THOUGHT CAME IN MY MIND THAT I MIGHT DIE. I MOVED SLOWLY TO RIGHT ON THE SHOULDER OF BRIDGE TO AVOID THE ACCIDENT AND STOPPED MY VEHICLE, NEXT THING I KNOW L HEAR LOUD SOUND, GAS & BURNING SMELL. I THOUGHT MY VEHICLE IS GOING TO CATCH FIRE. I DON'T KNOW WHERE THE STRENGTH CAME IN ME AND I WAS ABLE TO GET OUT OF MY VEHICLE WALK AWAY 10-15 YARD AWAY FROM MY CAR. POLICE REPORT FILED - YES BOTH CARS DRIVER WERE TAKEN TO HOSPITAL IN AN AMBULANCE.

ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM
1 complaint
WHILE DRIVING AT HIGHWAY SPEED IN THE LEFT LANE OF A DIVIDED HIGHWAY, THE VEHICLE SUDDENLY AND WITHOUT NOTICE LOST ENGINE POWER AND POWER STEERING. THE WEATHER CONDITION WAS LIGHT RAIN AND THE ROAD WAS WET. I WAS ABLE TO MOVE OVER TO THE SHOULDER OF THE HIGHWAY AND RESTART THE ENGINE BUT IT DIED WITHIN TWO TO THREE SECONDS. I THEN RESTARTED THE ENGINE SEVERAL MORE TIMES AND WAS ABLE TO MAINTAIN A RUNNING ENGINE AFTER ABOUT 5 RESTART CYCLES. THE ENGINE LOSS OF POWER HAS BEEN TRACED BACK BY A MERCEDES REPAIR CENTER TO A MALFUNCTION OF THE ELECTRICAL WIRING HARNESS CONNECTED TO THE FUEL PUMP IN THE GAS TANK. THIS INCIDENT DEMONSTRATES THAT THE ELECTRICAL SYSTEM MALFUNCTION REPORTED UNDER ITEM #10745399 OCCURS IN WET ROAD CONDITIONS AND NOT JUST WHEN TRAVELING OVER A PUDDLE. MERCEDES REFUSES TO REPAIR THIS SAFETY RELATED DEFECT UNDER WARRANTY.
