  1. Filed Sep 21, 2026Failure Aug 8, 2026Bolingbrook, ILPower train, Steering, Unknown or other

    I am filing this complaint regarding NHTSA Recall 26V216 for my 2018 Mercedes-Benz E 400 4MATIC, VIN [XXX]. On XXX, the recalled driveshaft/universal-joint component failed, rendering the vehicle undriveable. At essentially the same time, the steering became effectively frozen and I could not steer normally. The recall materials I received warned of sudden loss of drive power, but did not warn of possible steering loss. The recall notice did not give an actual earliest repair date. Instead, it stated that I could take the vehicle to an authorized Mercedes-Benz dealer for repair at no cost. My disabled vehicle was taken to Mercedes-Benz of Orland Park on XXX, and I was provided a loaner that day. I was then told the corrected remedy was unavailable and might not be available until approximately XXX. The dealer discussed repair costs of approximately $9,000-$10,000, plus about $6,000 more if steering damage is confirmed. I was also told an available/older OEM driveshaft could potentially be installed if I paid for the repair while the corrected recall remedy remained unavailable. The dealer later requested return of the loaner while my vehicle remained undriveable. I escalated the matter to Mercedes-Benz USA and sent a formal demand on XXX, with a three-day response deadline. As of XXX, I had not received a substantive resolution. I request that NHTSA investigate the unavailable free remedy, adequacy of the recall notice, proposed paid repair, remedy delay, whether steering loss is an undisclosed consequence of Recall 26V216, whether stronger interim warnings were required, and whether Mercedes-Benz should provide continuous alternate transportation until the corrected remedy is available.

    The contact owns a 2018 Mercedes-Benz E 400. The contact received notification of NHTSA Campaign Number: 26V216000 (Power Train); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

  3. Filed Feb 3, 2026Failure Feb 3, 2026Homewood, ALSeat belts

    The driver-side seat belt retractor on my 2018 Mercedes-Benz E400 (W213) has failed to fully retract, leaving significant slack across the driver's chest and lap. An authorized Mercedes-Benz dealer has diagnosed the issue as a failed seat belt motor. This component is part of the vehicle's electronic PRE-SAFE system. Because the belt no longer retracts into its stowed position or maintains tension, the vehicle is in a state of non-compliance with Federal Motor Vehicle Safety Standard (FMVSS) No. 209 (Seat Belt Assemblies). Specifically, it fails to meet the retraction requirements necessary to ensure the webbing properly locates on the occupant's body. Furthermore, the failure of the motor disables the PRE-SAFE tensioning function, which is a critical safety system. Despite being a safety component and the vehicle being less than 10 years old, the manufacturer has refused to remedy this safety defect under the National Traffic and Motor Vehicle Safety Act. A non-retracting seat belt is an unreasonable risk to safety as it increases the probability of injury or ejection during a crash.

    The rear backup camera intermittently will open for a second, display the rear view (when in reverse), then immediately closes. This often happens after the trunk has been opened / closed, as when we go shopping and put items in the trunk. Sometimes it resets when you turn off the ignition and restart the car.

  5. Filed Dec 15, 2025Failure Dec 15, 2025Collierville, TNUnknown or other

    I am filing a complaint regarding the loss of safety-related and remote vehicle features on my 2018 Mercedes-Benz E 400 due to discontinued cellular connectivity between Mercedes-Benz and T-Mobile, effective 12/31/2025. This vehicle is paid for, has low mileage, and is otherwise in excellent condition. However, Mercedes-Benz has notified owners that key features will stop working, including remote start and safety-related services accessed through the Mercedes-Me app. As a consumer, I pay a monthly subscription for these services. This is the second Mercedes-Benz vehicle I have owned where features were removed after purchase due to technology decisions made by the manufacturer and its partners. In addition, the app has been unreliable for a significant period of time, often failing to function properly even while the subscription was active. Rather than correcting the issue, the service is now being eliminated entirely. As a woman who travels, the loss of safety features is a serious concern. These systems were a factor in my decision to purchase this vehicle and brand. The removal of functionality reduces vehicle safety, usefulness, and value, leaving the consumer to absorb the loss or install third-party systems. I am not seeking reimbursement. I am seeking accountability. Vehicles should not lose safety or core functionality while still within their reasonable service life. Consumers should not bear the consequences of manufacturer technology decisions made years after purchase. I believe this issue impacts many owners and raises concerns about vehicle safety, consumer protection, and long-term support of installed systems.

    This is NOT about my car with the VIN that I described. It is to report that my car saved my life thanks to ability to brake by itself when detecting accident. 2 months ago I almost collided with Tesla Cybertruck!. The reason that I almost was hit was that Tesla driver didn't yield at the intersection, and I did not see the fast-coming truck AT ALL because of how it is designed. I'm referring to lack of larger front, side and rear reflectors, etc. Existing lights are tiny, hidden and invisible at certain angles and lighting. Driver did not turn headlights on making this truck totally invisible because of its color, stainless steel that's grey and matching the color of light at that time of a day. I am very surprised that a vehicle like Tesla Cybertruck received certification to be driven on US public roads since it does not have a single reflector, red or orange, on either side or the rear/ front of the vehicle that's easily visible at all times and weather conditions endangering all public on the road. I would like to file a formal complaint against Tesla, DOT, NHTSA. Please inform me about the formal way of filing a complaint and all necessary forms that I will need to do so. This is in the best interest of all drivers, passengers and anybody who may get hurt or killed by this non-compliant vehicle. I have contacted Tesla via letter about 2 months ago but have not received any response from car Manufacturer who ultimately is responsible for designing dangerous vehicle, and DOT and other Agencies for issuing certification for a non-compliant vehicle.

    Two problems: 1. Axel grease found on carport cement multiple times. Mercedes refuses to look at the wheel bearings or axel. 2. Automatic steering wheel adjustment makes clunking noise. Mercedes refuses to replace until it fails. Both of those items should be covered under warranty which I think is why they refuse to fix them.

    ON MAY 30, 2020, AROUND 3 PM, MY SON WAS THE DRIVER AND MY WIFE AND I WERE THE PASSENGERS DRIVING IN JERSEY CITY, NJ (USA). WHILE CHANGING LANES ON THE ROAD, THE CAR SUDDENLY STOPPED FUNCTIONING. ALL DASHBOARD LIGHTS CAME ON AND IT SHOWED A CAR WITH ZIG ZAG LINES AND STATED INOPERABLE. WE WERE IN THE MIDDLE OF THE ROAD IN A DANGEROUS SITUATIONS WITH CARS GOING AROUND US. THE STEERING WHEEL FROZE AND THE BRAKES WERE NOT FUNCTIONING. WE TRIED TO RESTART THE CAR MANY TIMES WITH THE DASHBOARD LIGHTS COMING ON AND STATING INOPERABLE. AFTER A LITTLE WHILE, WE WERE ABLE TO PLACE IT IN NEUTRAL AND PUSH THE CAR TO SAFETY ON THE SIDE OF THE ROAD WHILE STILL BLOCKING A LANE. WE THEN CALLED THE MERCEDES SERVICE CENTER WHERE A TECHNICIAN TRIED TO HELP US VIA TELEPHONE BUT WAS UNSUCCESSFUL AND FINALLY 2 HOURS LATER, WE HAD TO HAVE THE CAR TOWED. THE FAMILY HAD TO TAKE UBER HOME. THE CAR HAS BEEN TOWED TO RAY CATENA MERCEDES IN UNION, NJ, USA AND WE RECEIVED A CALL THIS MORNING THAT THEY WILL INSPECT IT LATER ON TODAY.
