Showing 33,654 complaints for MERCEDES-BENZ
Incident date: Aug 25, 2026
From: [XXX] Phone: [XXX] Email: [XXX] SUBJECT: Vehicle: New Mercedes-Benz GLB 250 VIN: [XXX] Current Mileage: 39,660 Total Purchase Price: $48,450.00 To Mercedes-Benz USA Corporate Management and Dealership Service Director, This letter serves as a formal written statement regarding an ongoing, unremedied mechanical failure that has now escalated into a severe, life-threatening safety hazard.
... I am officially rejecting the dealership's requests to appraise or trade in this vehicle, and I am demanding a full manufacturer repurchase (buyback) of the vehicle for my purchase price, down payment, finance charges, associated fees and taxes under the federal Magnuson-Moss Warranty Act. Background of Failed Repairs My vehicle has already spent 15 cumulative days out of service for an ongoing engine defect. An authorized Mercedes-Benz dealership recently diagnosed the vehicle and performed a major cylinder head assembly job/replacement to resolve engine misfires and a persistent Check Engine Light. This defect is well-documented by Mercedes-Benz under its active 15-year/150,000-mile extended warranty program for the M260 engine cylinder head. The Critical Safety Incident Despite the recent cylinder head replacement, the Check Engine Light has returned, signaling a total failure of the repair. More critically, on August 25, 2026 while driving the vehicle, the engine catastrophically stalled without warning in live traffic. Due to the sudden loss of engine power, power steering, and braking assist, I was nearly involved in a severe traffic accident. This vehicle is inherently unsafe, unroadworthy, and poses an immediate danger to myself and others on the road. Formal Demands Immediate Buyback Processing: Because this vehicle cannot be repaired after a major engine overhaul and now actively stalls, I am demanding a full refund of my purchase price, down payment including all associated taxes, fees, and finance charges.

My 2022 Mercedes-Benz EQB 350 4MATIC (VIN [XXX]) is subject to NHTSA Recall 26V073 / MBUSA campaign 2026020004 for a high-voltage battery defect that may cause a thermal event/fire while parked or driving. Mercedes-Benz has determined that the permanent remedy requires replacement of the high-voltage battery, but MBUSA has confirmed that a replacement battery is not currently available for my VIN
... and has provided no firm repair date. Pending repair, Mercedes instructs owners to limit charging to 80% and park outside rather than in a garage or enclosed structure. These restrictions materially impair normal use. My wife's work requires frequent travel between [XXX] and [XXX], plus secure indoor garage parking at federal government facilities. The 80% charge restriction reduces usable range, while the required indoor parking conflicts with Mercedes' safety guidance. MBUSA has also confirmed in writing that my VIN is currently subject to a recall-related stop-sale and that sale restrictions remain until the recall remedy becomes available. An authorized Mercedes dealer has declined to provide a normal trade valuation because of the recall/stop-sale situation. MBUSA reviewed and denied my repurchase request, offering only possible loaner, storage, or rental assistance. I am filing this complaint to document that the permanent safety remedy is unavailable, the interim restrictions materially impair use, and the vehicle is under stop-sale with no firm remedy date. I request that NHTSA review the remedy delay and whether acceleration or other recall action is warranted.

Rear hatchback for 2026 Mercedes GLC sensors
Incident date: Aug 25, 2026
While driving at slow speed (approx 27 mph) on an inclining road, the automatic braking system when off and abruptly slowed down the vehicle. Fortunately there was no one immediately behind my car and there was no apparent reason for the emergency braking. The sidewalk did have a person with a dog off to the right at the time but they were completely away from the car walking on a sidewalk. This

Incident date: Jul 27, 2026
On July 27, 2026, while driving my 2019 Mercedes-Benz AMG GT 63 under normal conditions, the vehicle suddenly displayed a suspension warning stating, “Malfunction — Drive at Max. 50 mph.” The warning appeared while the vehicle was in motion; I had not received this suspension warning before the incident. I photographed the warning when it occurred and presented the vehicle to an authorized M
... ercedes-Benz dealership for diagnosis and repair that same day. On July 30, the dealership confirmed in writing that the vehicle had a leaking front air strut and required replacement of the front air strut. The dealer advised that the required part did not have an established arrival date. As of August 24, the vehicle remains at the authorized dealership and has not been returned to me. I consider this a safety concern because the suspension malfunction occurred without prior warning while the vehicle was being driven and was serious enough for the vehicle itself to instruct the driver not to exceed 50 mph. A failure affecting an air-suspension component during operation raises concern regarding vehicle ride height, stability, handling, and the ability to safely operate the vehicle at normal highway speeds. The failed component and vehicle are presently in the possession of the authorized Mercedes-Benz dealership and should therefore be available for inspection. The condition has been confirmed by the dealership as a leaking front air strut requiring replacement. The vehicle has a significant prior repair history that includes a documented steering-malfunction warning, drivability complaints, vibration, repeated check-engine warnings, and extensive mechanical repairs. I am not asserting that each prior condition shares the same cause as the present suspension failure, but I am reporting that history because it may be relevant to NHTSA's evaluation of the vehicle's safe operation. I have retained the contemporaneous photograph of the suspension warning, the dealership's writRead more

This vehicle with 19711 mileage was parked in the driveway. The engine started normally, but a red error message stated, "Service Required Do Not Shift Gears Visit Dealer". I contacted the local dealership and Mercedes Roadside Assistance was not able to reset the software. The driveshaft was disconnected and two tow trucks were needed to pull the vehicle out of the driveway and then tow to the
... dealership. The technician found "internal electrical fault in ISM causing shifter not to come out of park". The electronic shifting unit was replaced and the vehicle is functioning normally. The switching unit did not have any external damage and there was no evidence of corrosion on the electrical terminal. This vehicle has had all of the recommended service at the dealership. It was previously serviced on Nov. 5, 2025 for recall 2025070011(update controll unit software). There were no transmission error codes. In approximately February 2026, the vehicle had not been started and the battery was dead. I jumped the vehicle to start it and then used a battery charger. No one was injured. Luckily this occured in my driveway. Mercedes assistance was appreciated. However, there was absolutely no indication of a problem prior to this. There is no mechanism to shift into neutral to move the vehicle unless the drive shaft is disconnected. If this were to occur on a busy street, it is possible that many people could have been injured. I am reporting this "near miss" in case there are other similar problems that have been reported. I believe that the unit will be inspected by Mercedes as well.Read more

Vehicle: 2022 Mercedes-Benz GLC 300 4MATIC Component: Electronic Parking Brake (EPB) / Service Brakes Summary of Complaint: This vehicle has an ongoing, unresolved Electronic Parking Brake (EPB) defect. The amber EPB warning light has recurred multiple times, including most recently after a $3,000 dealership repair intended to correct this exact fault. Timeline: 1.Following a brake pad replac
... ement, the vehicle experienced an EPB failure, brake fluid loss, and a gear shift interlock lockout — leaving the vehicle inoperable. 2.The vehicle was taken to a Mercedes-Benz dealership for repair. This resulted in a dispute over unauthorized work performed and a request for goodwill coverage tied to a known Mercedes-Benz EPB recall. 3.I paid approximately $3,000 to the dealership for a repair specifically to resolve the EPB fault. 4.Approximately a few weeks after this paid repair, the same amber EPB warning light returned, indicating the underlying defect was not resolved. Safety Concern: The EPB is a safety-critical system. Repeated, unresolved failure of this system — including a prior incident involving brake fluid loss and a gear shift interlock lockout that left the vehicle inoperable — represents a real risk of parking brake failure and loss of vehicle control/immobilization in normal use. Additional Notes: •This defect appears connected to a known Mercedes-Benz EPB recall. •I have photo documentation of the recurring warning light (dated) and the dealership repair invoice for the $3,000 repair. •I have an open case with Mercedes-Benz Customer Assistance regarding this issue.Read more

I was told by the investigators that the fire was caused by an electrical component under the passenger seat that Mercedes is well aware of. My life was placed in danger because of the Inhalation of forever chemicals and lung damaging smoke and super heated air. Problem confirmed by dozens of owners who experienced and documented the very some accounts, some who have reported contacting the NHTSA
... years prior to my experience but nothing was done to save lives or prevent losses. The American Freedom insurance investigator told me in writing what caused the fire. Nothing gave any indication that my life was in danger not a light, an alarm nor the monthly Connect service I paid for every month. Nothing gave me an indication that something like this was going to happen.Read more

On XXX, my 2016 Mercedes-Benz GLC 300 was serviced at a Mercedes-Benz dealership for a B Service, including replacement of the rear brake pads and sensor. The rear wheel had to be removed to perform this work. On XXX, approximately 7 days later, my wife was driving the vehicle with our [XXX] son and his friend as passengers when the LEFT REAR WHEEL COMPLETELY SEPARATED from the vehicle while in m
... otion on a public road. A truck was approaching from behind. The family narrowly avoided a serious collision. Police responded to the scene and an officer directed traffic while the vehicle was towed. The lug bolts were recovered from the roadway. The dealership's General Manager later asked me to return the lug bolts, which I did. The vehicle required repair of the wheel and hub assembly at a collision center. I was given no written explanation of why the wheel separated. Separately, after the XXX service I noticed a transmission problem that was not present before. On XXX it became dangerous: coming out of stops at traffic lights and stop signs, the transmission would slip into Neutral instead of engaging Drive, and after several attempts would drop directly into third gear with a hard jerk. This creates a serious risk of being unable to accelerate away from a stop in traffic. I documented this on video and provided it to the dealership. No injuries have occurred, but both incidents were near-misses with a high risk of a crash or injury. I am reporting this so the potential defect and the quality of the safety-related service are on record. I have photographs and video from the wheel-separation scene, the transmission video, the service records, and related documentation available on request.

My 2024 Mercedes-Benz GLE 350 unexpectedly braked on its own on two separate occasions while I was driving at a low speed, approximately 5 to 10 mph. There was no warning chime, no “BRAKE!” message, and no other warning immediately before the vehicle suddenly braked. One of the incidents occurred while driving through a drive-thru. The sudden braking was strong enough to jolt a properly restr
... ained rear-seat passenger forward and caused discomfort around the waist area. I also received a dashboard warning stating “Active Parking Assist and PARKTRONIC Inoperative.” The vehicle was taken to an authorized Mercedes-Benz dealership, where it was inspected, scanned, test-driven, and a software update was performed. The dealership was unable to reproduce the unexpected braking and did not identify a confirmed cause for the braking incidents. The vehicle remains available for inspection upon request. I am concerned that this may be an intermittent safety-related malfunction involving the driver assistance, parking assistance, sensor, or braking systems because the vehicle applied the brakes unexpectedly without warning.Read more

While driving at 50mph, the vehicle came to a full stop in 2 seconds by auto breaking (to avoid collision) when there was no object or vehicle in front of the car.

When the vehicle was taken to the service center, th
... e computer systems showed no record of this incident. However, I do have a dashcam footage of it. In the video, you can clearly see a stopped car on the left turn lane (the break lights of the car is visible and the car is stationary when the video is analyzed frame by frame.) The driving lane is curving to the right and the vehicle is also turning to the right following the lane. (this is verified by following the double yellow line - then the single solid white line and vehicle's motion to the right.) Despite all this, the car slammed the breaks and stopped. The video is seen by the service center workers as well. They updated the software on the car at the time of service. An escalated ticket was also created with Mercedes corporate office with case number: 23763407. At the very least, the cars should be keeping records of collision avoiding breaking administered by the car's system so when you're at the service center, there's a record of what happened. This incident could have resulted into a high-speed collision with severe injuries to the people in both vehicles and one pet. And if it did, the car would have shown zero record of functions performed and the drivers would have been blamed.Read more

An inspection of my vehicle on August 6, 2026 disclosed that the rear subframe has corrosion, including perforation. It is my understanding that this problem has been identified in mine and many other Mercedes-Benz models, and that Mercedes-Benz has offered an extended warranty to replace the subframe in certain of these models, but my model for the year it was manufactured was not included. I w

I request that NHTSA investigate whether 2023 Mercedes-Benz GLA 250 vehicles and other H247 vehicles are susceptible to foreign-material intrusion into the HVAC blower system and whether the existing intake grille/sealing design adequately prevents debris from reaching and damaging the blower motor. I further request that NHTSA determine whether Mercedes-Benz has received additional warranty clai

The instrument cluster on my 2011 Mercedes-Benz S550 (W221) is locked by a persistent red “Battery Not Charged” warning message. This message appears even though the charging system is working correctly (normal charging voltage, new battery, and new battery sensor installed). Because the cluster is locked, I can no longer: • View or reset tire pressure (TPMS) • Access the digital speed d
... isplay • Adjust or enable certain lighting functions, including daytime running lights • Adjust seatbelt settings • Turn the blind spot monitor on or off • Control PRE-SAFE braking / related safety systems • Use other instrument cluster menus and driver information displays The problem began after a low-voltage event (battery went dead and the car only partially cranked). Clearing fault codes does not permanently resolve it — the message returns immediately. This is a known software issue on facelift W221 models that requires an instrument cluster software update and SCN coding to fix. The locked cluster prevents access to required safety information and multiple safety-related vehicle functions. The vehicle and components are available for inspection.Read more

An Intoxalock ignition interlock device was installed in my 2023 Mercedes-Benz E-Class on May 7, 2026. Following installation, the vehicle experienced repeated electrical/no-start problems and incidents in which it became immobilized and could not be moved, requiring towing. On one occasion the vehicle became disabled on a roadway/highway, leaving me in a dangerous position with traffic passing a
... round me. When the vehicle is immobilized, I cannot simply move it to a safe location, and Intoxalock has not been able to restore vehicle operation remotely. I have had to wait for towing assistance, sometimes for extended periods. Independent diagnostic/service facilities have evaluated the vehicle. One attributed battery drain to the Intoxalock-related problem. Another attributed starter damage to it. Service documentation also reflects diagnosis of the Intoxalock system and reinstallation/reconnection of the device and wiring. Documentation is available, and the equipment/vehicle can be made available for inspection upon request. The vehicle now displays numerous dashboard warning lights and is not operating normally. Safety-related systems are malfunctioning, including ABS, parking assistance, camera functions, and automatic braking/collision-avoidance functions that previously operated normally. I am concerned that the Intoxalock device, its installation/wiring, or its interaction with this vehicle’s electrical/electronic systems may be contributing to these failures. I am requesting that NHTSA investigate whether this aftermarket ignition-interlock equipment presents a safety or compatibility risk, particularly when a vehicle can become immobilized in traffic and safety systems may be affected.Read more

The suspension has malfunctioned on a car with only 89,000 miles. Upon starting the car, the vehicle says to please wait while it is rising.

This is a safety concern when driving on the highway and around town. This appears to be an issue on other Mercedes models, suc

... ty to to shift correctly out of traffic. Mercedes benz has a technical service bulletin on this problem and is aware that the 9G-Tronic - internally designated as the 725 transmission (fault code P07B700) is defective and known to experience sudden pressure sensor failures or valve body faults within the transmission control unit which prevents the car from shifting gears corrected or forces limp mode. The repair is a minimum of $5,200. MBZ has known this is a defect and wide spread issue but unwilling to contribute to the repair or recall or respond to my letters and the inquiries of other vehicle owners I have spoken to that have the same issues. It is a catastrophic mechanical failure from a sensor they know is bad and is occurring shortly after warranties are expiring. It is putting all of our lives and the lives of others at risk of an accident due to the failure of their part. Thank you for your consideration.Read more
