UNKNOWN. I was vacuuming the car and it went dark. Then in the instrument cluster was a PRE-safe warning light, then a PRE-Safe functionality message. Then the car would not start or crank nothing. The car wakes up when I put the key in and after a few seconds goes dark. I saw a recall campaign number 22V-168 and 2022040003. Cannot get help. Vehicle is available for inspection but cannot drive it.
... I was not even driving the car it was parked. Trying to get manufacturer to check the recall same symptoms. no one has check on it. Tried to get VMI but cannot release to me since I purchased it in 2023. I get no open recalls, from manufacture. I got 6 from NHTSA and 2 from Customer Service recall and then 3 from a dealer. I have no info except I know this was a recall and want help with this please. I need transportation. I am concerned for my safety and if it was driving I wouldn't drive it to dangerous even more with the misinformation plus my safety and others. Thank you for your time.Read more

The left side of the digital instrument cluster in my 2022 Mercedes-Benz GLE 450 intermittently goes completely blank while driving. When this occurs, I cannot see critical vehicle information, including my speed, fuel level, warning indicators, and other important vehicle functions. The failure happens randomly and without warning. Approximately two months ago, I took the vehicle to an authorize
... d Mercedes-Benz dealership for this issue. The dealer stated that the problem was corrected with a software update; however, the instrument-cluster failure has now returned. This creates a serious safety concern because I may be unable to monitor my speed, determine how much fuel remains, or see urgent warnings and system alerts while operating the vehicle. I am concerned that this recurring malfunction could contribute to a crash or leave the vehicle occupants stranded. I am requesting that NHTSA investigate whether this is a widespread safety defect affecting the instrument clusters in these vehicles.Read more

However, they are actively denying coverage for my CLA 250's M270 engine variant, despite the two vehicles sharing nearly identical engine blocks, matching subcomponents, and the exact same broken part. Because of this unfair engine code technicality, Mercedes-Benz is forcing CLA owners to pay thousands of dollars out of pocket for a recurring problem they fix for free on a C-Class. I urge the NHTSA to look into this engine loophole and force Mercedes-Benz to include the M270 engine variants under the 15-year/150,000-mile free repair program.Read more

Incident date: Aug 28, 2026
What component or system failed or malfunctioned, and is it available for inspection upon request? The Forward Collision Avoidance / Active Brake Assist (Automatic Emergency Braking) system failed by falsely identifying a non-existent threat and initiating uncommanded emergency stopping. The vehicle and its onboard control modules are fully available for physical and diagnostic inspection upon req
... uest. How was your safety or the safety of others put at risk? While traveling at approximately 35 mph, the vehicle suddenly executed maximum emergency braking with zero warning and no preceding obstacles, vehicles, pedestrians, or road hazards present. The violent deceleration caused maximum seatbelt restraint locking force, resulting in sudden physical impact trauma to a 6-month pregnant passenger and acute dizziness/disorientation for both occupants. This malfunction creates a severe, immediate risk of high-speed rear-end collisions from trailing traffic and unexpected loss of vehicle control. Has the problem been reproduced or confirmed by a dealer or independent service center? Not yet. The vehicle has not yet been serviced or inspected by a dealer or independent service center following this event. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Neither the manufacturer, police, insurance representatives, nor third-party investigators have inspected the vehicle or component since the incident occurred. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps, error messages, chime alerts, or functional symptoms prior to the sudden brake activation. The Active Brake Assist system triggered immediately without prior warning.Read more

While the vehicle was being operated normally, it caught fire. We were driving on a summer day in August. Conditions were humid, with temperatures in the mid-80s. The vehicle was on the return leg of an approximately 30-mile drive. Traffic was somewhat heavy, with speeds generally below 20 mph and occasional stops. We first noticed a slight burning smell, followed shortly afterward by a distinct
... puff of white smoke coming from under the hood on the passenger side, near the windshield. We immediately decided to stop the vehicle and get out. Within approximately 30 seconds, we observed the first visible flames. Within about one minute, the fire had spread rapidly and the vehicle was engulfed in flames. By approximately 3½ minutes, the entire front half of the vehicle had been destroyed by the fire. Parts of the vehicle were blown off during the fire, with some debris traveling across the roadway and into the nearby woods. Fortunately, there were no injuries because we recognized the danger and exited the vehicle quickly.Read more

I am a mechanic speaking on the behalf of a customer; this customer is experiencing problems with her rear subframe. The older generation of her car has a famous issue with rear subframe rusting out. Her car uses an updated part number that is almost identical in construction to the failure prone part that was famous for rusting out, although they are NOT the same number. The failure prone number
... is 2123503805 or 2043500141, they are installed on the older chassis, w204, w212, etc. The part that is in THIS vehicle is 2123503605, the construction is almost identical to the part numbers listed for the w212 and w204 provided above. There is no drainage holes provided for water that has entered through rain or any other detritus that will permeate on the road's surfaces through natural progression of the vehicle's life, like on the older chassis. The material used is steel with paint on the outside instead of some sort of encapsulation that coats both inside and outside surfaces. And because these don't have any sort of ability to evacuate any substances, they are interacting with unprotected metal and will react into rust. This failure can lead to misalignment at the very minimum of problems, at the worst, it can cause control arms falling off, causing wheel hub assemblies to fall off, this shouldn't have to be explained but this can cause major injury or death, not only to the passengers to the vehicle, but to others who share the misfortune of being at the wrong place at the wrong time. And, the understanding of these not being the SAME part shouldn't warrant the extension of the recall to these particular vehicles, but the failures are similar to what was seen before on other older vehicles and should warrant further investigation. With hope, this could just be an isolated incident, but since patterns are uncanny, this should be investigated with some interest to the public wellbeing. Cordially Naseam F.

The affected component is the high-voltage traction battery and related battery management and bus-bar connection systems. My vehicle is available for inspection upon request. I am reporting a safety concern because my vehicle is subject to NHTSA Recall 25V050, which identifies a risk that the high-voltage battery could fail internally and cause a fire while parked or driving. It is also subject
... to NHTSA Recall 25V487, which identifies a defect involving the high-voltage battery bus-bar connection that may cause a sudden loss of drive power without warning. A battery fire could endanger vehicle occupants and people or property near a parked vehicle. A sudden loss of propulsion while driving could increase the risk of a crash. I have not personally experienced a vehicle fire or a sudden loss of drive power. However, I am being asked to continue operating and making lease payments on a vehicle with identified high-voltage battery safety defects and no completed effective remedy available for my vehicle. The currently available guidance limits charging to 80%, which reduces the vehicle’s usable range and practical value. The vehicle’s recall status has been confirmed through NHTSA and Mercedes-Benz recall information. To my knowledge, no dealer repair has been completed that eliminates these safety concerns. The vehicle has not been inspected by police, insurance representatives, or an independent service center in connection with an incident because no crash, fire, or loss-of-power event has occurred. Before any failure, I have not observed a warning lamp, warning message, or other battery-related symptom. My concern is that Recall 25V487 describes a potential sudden loss of drive power without warning, and Recall 25V050 identifies a potential battery-fire risk, including while the vehicle is parked.Read more

Incident date: Aug 1, 2026
Component/System: The intake camshaft positioner/adjuster on cylinder bank 2 of the M276 V6 engine has failed, along with associated timing components. The vehicle (2018 Mercedes-Benz E400, VIN [XXX]) remains unrepaired and is available for inspection upon request. Safety Risk: The engine produces a loud metallic rattle on cold starts, indicating loss of proper camshaft timing control. If unaddre
... ssed, camshaft timing deviation can progress to timing chain failure, which on interference engines can cause valve-to-piston contact and sudden, severe engine damage or loss of power while driving, posing a risk to vehicle control. Confirmed by Dealer: Yes. Mercedes-Benz of Catonsville (RO# [XXX]) diagnosed the issue and confirmed stored fault code P002177, indicating the intake camshaft position on cylinder bank 2 deviates from its specified value. The dealer's own notes state camshaft adjusters "are prone to failure and commonly damage camshafts when they fail." Manufacturer Notified: I contacted Mercedes-Benz USA directly (Case #[XXX]) to request they address this repair, citing that this camshaft/timing failure is a known, recurring issue on M276-equipped vehicles, supported by Mercedes' own technical service bulletins (TSB LI05.10-P-056435 and TSB LI05.20-P-059966) describing this exact failure pattern. Despite multiple attempts, including a promised callback that was never received and nearly an hour on hold with no resolution, Mercedes-Benz USA has not adequately responded or taken action. Warning Signs: The check engine light illuminated in early August 2026, prompting a dealer visit. The cold-start rattle was identified by the dealer during diagnosis the following day. No prior symptoms were noticed beforehand. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)Read more

On XXX at approximately 8:45 am , at the Life Time parking lot, [XXX] the registered owner of the vehicle was slowly pulling the 2025 Mercedes Benz GLE 450 e into a parking space and was actively applying the brake as she entered the space. While she was braking, the vehicle suddenly and unexpectedly accelerated forward. she applied the brakes forcefully and continued braking hard throughout the e
... ntire unintended forward movement in an effort to stop the vehicle. Despite her continuous braking effort, the vehicle continued forward, traveled across the raised concrete curb, through the landscaping and bushes, across the grass and paved pedestrian path and toward the wetland reed area. She ultimately brought the vehicle to a stop. The distance from where the unexpected acceleration began to where the vehicle finally stopped was subsequently paced off at approximately 15 yards (45 ft). after the sop a dashboard display was photographed showing the message :ATTENTION ASSIST-SYSTEM SUSPENDED. The photograph documents the message after the event; no conclusion is being drawn from that message regarding the cause of the unexpected acceleration. Photographs taken after the event show tire marks on the paved path, disturbed grass/landscaping, the vehicle near/over the concrete curb, debris /vegetation on the tire tread, the drivers pedal/floor-mat area, and the dashboard message described above. I have requested that Mercedes Benz preserve potentially relevant diagnostic, event, control-module and connected -vehicle data before it is overwritten or altered. I am submitting this complaint because the event warrants evaluation as a potential motor-vehicle safety issue. I am not asserting a specific technical cause.

2. Service Department Misconduct —XXX Appointment On XXX, I brought my vehicle to the dealership’s service department for a pre-scheduled and confirmed appointment regarding a safety-related warning involving the emergency brake system. Despite having provided a full description of the issue at the time of booking, I was informed upon arrival that the diagnostic process would take more than fi
... ve hours. When I asked about a loaner vehicle — standard practice at Mercedes-Benz dealerships in cases of extended service — I was refused, even though five courtesy vehicles were visibly parked on the lot and at least two other customers who arrived after me were provided loaners and expedited service that same day. I was made to wait in the lobby for the entire day. At approximately 5:00 p.m., just before closing, and despite no diagnostic work having been performed on my vehicle, a loaner vehicle was suddenly made available to me. This inconsistent and apparently discriminatory treatment in the allocation of loaner vehicles and service priority is unacceptable and warrants review. 3. Lack of Communication and Missing Documentation Following Service The technician assigned to my vehicle, [XXX], told me he would call me on Monday, XXX, once diagnostics were complete. He did not call. Instead, I received only an automated text message on Tuesday, XXX, stating the vehicle was ready — with no phone call, no email, and no explanation or summary of the work performed, contrary to standard practice at other Mercedes-Benz dealerships I have used. When I called to follow up, the technician did not answer despite multiple voicemails. I called the service department directly and asked for a supervisor; none was made available. After approximately one hour of calling the main dealership line, a sales associate attempted to reach the service department on my behalf and also received no answer. I then reached the technician directly. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)Read more

2. Service Department Misconduct —XXX Appointment On XXX, I brought my vehicle to the dealership’s service department for a pre-scheduled and confirmed appointment regarding a safety-related warning involving the emergency brake system. Despite having provided a full description of the issue at the time of booking, I was informed upon arrival that the diagnostic process would take more than fi
... ve hours. When I asked about a loaner vehicle — standard practice at Mercedes-Benz dealerships in cases of extended service — I was refused, even though five courtesy vehicles were visibly parked on the lot and at least two other customers who arrived after me were provided loaners and expedited service that same day. I was made to wait in the lobby for the entire day. At approximately 5:00 p.m., just before closing, and despite no diagnostic work having been performed on my vehicle, a loaner vehicle was suddenly made available to me. This inconsistent and apparently discriminatory treatment in the allocation of loaner vehicles and service priority is unacceptable and warrants review. 3. Lack of Communication and Missing Documentation Following Service The technician assigned to my vehicle, [XXX], told me he would call me on Monday, XXX, once diagnostics were complete. He did not call. Instead, I received only an automated text message on Tuesday, XXX, stating the vehicle was ready — with no phone call, no email, and no explanation or summary of the work performed, contrary to standard practice at other Mercedes-Benz dealerships I have used. When I called to follow up, the technician did not answer despite multiple voicemails. I called the service department directly and asked for a supervisor; none was made available. After approximately one hour of calling the main dealership line, a sales associate attempted to reach the service department on my behalf and also received no answer.

I get a message saying "Active Parking Assist and PARKTRONIC Inoperative See Operator's Manual" every time I start the car. Then when going through a car wash, PARKTRONIC cannot be switched off any more as part of the "Car Wash Mode" (that also folds the rearview mirrors and shuts the windows).

During an inspection, an authorized Mercedes-Benz dealership discovered severe corrosion and perforation, including holes, in the rear subframe of my 2015 Mercedes-Benz GLA. There were no warning lights or messages alerting us to the condition before it was discovered. The dealership confirmed that the subframe requires replacement and estimated the repair at approximately $6,000. The vehicle has
... approximately 140,000 miles. The rear subframe is a structural component that supports suspension components. Its advanced corrosion and perforation create concern that it could weaken or fail while the vehicle is being driven, potentially affecting vehicle stability and control. The vehicle and affected component are available for inspection upon request, and photographs of the corrosion and holes are available. Mercedes-Benz USA was notified of the problem but has not agreed to cover the repair. Mercedes-Benz has issued a 20-year/unlimited-mile extended warranty for corrosion with perforation of rear subframes on several other Mercedes-Benz models, but the GLA is not currently included. I am reporting this because the same type of premature structural subframe corrosion appears to be occurring in this vehicle and may present a safety defect affecting other GLA owners.Read more

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.
