I am reporting a potentially serious vehicle safety issue involving a 2022 Mercedes-Benz GLC after a fatal crash. I was seated in the left rear seat. One occupant died and multiple people were injured. According to the Florida Highway Patrol crash report, the left curtain air bag was listed as “Equipped; Not Deployed,” while the right curtain air bag was listed as “Equipped; Operative; Deployed.” I suffered serious injuries while seated on the same side where the curtain air bag did not deploy. Before the crash, I remember hearing an unusual metallic rattling/clanking noise from the vehicle. I do not know what caused the noise or whether it contributed to the crash, but it occurred before impact. A family member later reported this pre-crash noise to the vehicle’s insurer. Law enforcement indicated that the vehicle’s event data recorder (EDR/“black box”) would be downloaded, but the crash report later stated “EDR Downloaded: No.” To my knowledge, the EDR data was never retrieved or preserved. The insurer later sold the vehicle as salvage before I was able to arrange an independent defect inspection, so the vehicle is no longer available to me for examination. I am not claiming that a defect has been proven. I am asking NHTSA to review whether the documented left-curtain nondeployment, in a crash severe enough to cause a fatality and multiple injuries while the opposite curtain air bag deployed, warrants investigation of the air bag/restraint system or another vehicle componen

The vehicle has experienced two separate incidents of significant loss of power/acceleration. First incident – January 2024, Clarksville, TN: While driving downtown, the vehicle suddenly lost significant power and could not provide normal acceleration. The estimated remaining range was approximately 50 miles. The vehicle was subsequently inspected/serviced by Mercedes-Benz/dealer personnel, but the underlying cause was not conclusively identified or resolved. Second incident- [XXX] [XXX]: While driving in the first lane of [XXX], the vehicle suddenly lost significant power/acceleration when the estimated remaining range was approximately 75 miles. There were no warning alarms or messages before the loss of power. My wife and child were in the vehicle. The vehicle could not provide normal acceleration in highway traffic, creating an extremely dangerous situation. The incident nearly resulted in a serious traffic accident, and my wife had to take immediate action to help avoid a potential collision. The vehicle was subsequently inspected by Mercedes-Benz/dealer personnel, but the specific loss-of-power condition was not conclusively reproduced or confirmed under the circumstances in which it occurred, and the underlying cause was not identified or resolved. The vehicle has therefore experienced this type of serious power-loss condition twice despite service attempts. I can no longer safely drive or intentionally test the vehicle to reproduce this condition. Attempting to drive

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 replacement, 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 t

My 2022 Mercedes-Benz GLC 300 (17,700 total miles) suffered a catastrophic structural engine block failure and an explosive loss of propulsion while driving at highway speeds. This occurred exactly 6 days and 183 miles after a franchised Mercedes-Benz dealership performed the official fuel pump impeller safety recall (NHTSA Campaign 23V-445).The dealership's official repair invoice documents that the technician custom-modified the recall remedy by reusing parts, explicitly stating: 'Relocated floater from old pump onto new fuel pump.' Simultaneously with the mechanical engine failure, a 'Reduce Engine Oil Level' message flashed on the dashboard, indicating severe fuel dilution from the compromised fuel system.The dealership is actively violating federal recall mandates by refusing to investigate this failed safety remedy unless I sign an open-ended financial check for a diagnostic and teardown fee. They have also revoked my substitute transportation to coerce payment. Mercedes-Benz USA Corporate Case Number 23652724 has been opened. I am requesting a federal safety investigation into this dealer's non-compliant recall remedy execution."

I have experienced 4 incidents of the car accelerating on its own. I have taken it to the dealership twice and they are unable to reproduce the problem. Problems began occurring in 2025 and occurred again this past week (August 20246). In the most recent incident I was accelerating on an "on ramp". The car suddenly took hold and continued to speed up despite my foot not being on the gas. I had to drive the car to safety with my foot on the break. The moment I took my foot off the break it would speed up. The floor mat was not touching the gas in all of the instances of this occurring. The gas pedal was not stuck to anything. I nearly avoided a serious accident as where i was trying to merge was running out of a lane and a cement block was in front of me. I was also with an infant and 2 year old in my car. There have been no warning messages when this occurs.

While driving down a busy neighborhood street 2 lanes with cars on both sides making it a 1 lane road pulled over to the side a little to let cars pass. All of a sudden ALL electrical and engine stopped and turned off. Only thing that was powered was instrument cluster with multiple warnings like SRS Malfunction, Steering Malfunction, SOS Inoperative, Parking Brake and more. We believe the car had also shifted to park on its own. No power to anything not even hazard lights. Nothing electrical had any sort of power. Could not even turn car off completely could not get the instrument cluster to turn off with ignition button. When I say everything electrical had no power I mean everything except instrument cluster. Hazard lights power locks, lights of any kind, ignition switch, gear selector, windows, sos feature, nothing had power. I could not imagine having this issue driving on the interstate and having the car completely loose ALL electrical power and what could happen to specially with a SRS malfunction and issue with steering. Had to have a wrecker come with wheel dollys because car could not be put in neutral and towed to Mercedes dealer. Upon their inspection they found the Circuit 30T relay to be stuck in the open position which killed power to everything so the technician replaced the engine compartment pre-fuse panel. It is such a unsafe and very hazardous issue to have a relay failure to where all power is lost especially if you were driving on interstate especially

My vehicle got stuck on a EPB(electronic parking brake) and I was unable to disengage it. I tried a few things and none worked. I contacted Mercedes to tow it to the dealer and the tow truck came and driver had to “drag” my vehicle on to the flatbed. My car has been at Mercedes for 5 days now and they gave me a response saying that they are having a hard time trying to disengage the EPB. I’m aware of a EPB recall but my model is specified as being a part of it, however the issue is closely related to the recall so please take further interest in my situation because it could be the start of a new recall. The dealer says they have tried and failed to disengage it. My car was working just fine so please take further look at a possible software glitch for the EPB.

My vehicle had check engine lights on throughout the last couple of years. Every time I bought it to the dealer, they ignored it and said the light went off. The machine doesn't pick up anything. Now the check engine light is on and the cylinder head and diagnostic head, something is wrong. They will fix the diagnostic head but not the cylinder head. The dealership knew there was ongoing issues but did nothing to correct it. The sales department already screwed me as well. The older models are recalled for the same issues and now the the newer vehicles like mine are having the same EXACT problem.

On Saturday 12/6/25, I put my 15 year old cat in his carrier in the back seat and closed the door. I got into my car and opened my garage door. I started my MBGLC300 and began backing my car out of my garage. As soon as the car rear end cleared the garage, I heard an explosion "BOOM", and the sound of breaking glass. I pulled back into my garage only to find the entire back window had exploded... all the glass was gone, and the back windshield wiper was dangling out of its housing from the pane (trim). I hit nothing! Nothing hit me! I got back into my car and drove the 10 minutes down the street to my vet's where he got his shot and I had him combed out (for any glass - thank goodness there wasn't any). While there, I phoned Dick Dyer Mercedes Benz (803.828.6952) at 8:57 AM,and spoke with Ryan Smith and told him I'd be down after the vet appointment. I pulled in at Dick Dyer service department shortly after 9:00AM. He said, "I've never seen anything like this." The whole glass was shattered into millions of tiny pieces. Smith got me into a Sedan and I drove home. On Monday Smith called to tell me Mercedes would not honor either my factory warranty (my car is a 2022) nor would my Extended Warranty (purchased at the time I bought my car) cover the $4,201.00 charge to repair. I'm a school teacher. I don't have that amount of cash. He said, "Ms. [XXX] , I want to believe you that you didn't hit anything, but I have to have proof."

I was involved in a severe front-end collision where my vehicle struck another vehicle with significant force. Despite the major impact, the front airbags did NOT deploy. The entire front end of the vehicle was crushed, including destruction of the radiator, damage to engine components, internal structural collapse, and leaking fluids. Based on the severity and direct frontal nature of the crash, airbags should have deployed but did not. As a result of the impact, I sustained a neck and upper shoulder injury and required medical evaluation. There were no warning lights or messages prior to the crash indicating any malfunction in the airbag or SRS system. The vehicle is available for inspection by NHTSA, the manufacturer, insurance, or an authorized Mercedes-Benz service center. This appears to be a possible failure of the airbag/SRS system during a qualifying collision.

Back Over Prevention › Sensing System › Camera

The rearview camera on my vehicle intermittently fails to function for unknown reasons, and the problem has recently become more frequent. For example, it may work normally when I first start the car in the morning and back out of my parking spot, but later the same day—such as when I arrive at work—the camera stops working completely. The display stays black and does not recover even after shifting between gears or restarting the system. After parking and locking the car for a while, the camera may start working again without any clear reason. Although I cannot recall the exact dates of the first occurrence, I have noticed a consistent pattern over time: the issue tends to appear during hot weather, particularly in summer. In recent months, the camera has almost completely stopped functioning. This unpredictable failure creates a potential safety hazard when reversing, as I cannot get help on the backup camera to provide visibility behind the vehicle.

I was driving home on a 4 Lane Expressway on a Saturday afternoon, it was mildly raining with the roads a little wet. I suddenly lost control of the car and could not control the steering wheel, the car ended up hydroplaning and I lost control it ping-ponged across four expressway lanes back-and-forth about 20 to 25 times with zero control of the steering wheel, barely missing the medians and other cars. It should have been a massive catastrophe. Cars around me you had to stop and swerve around me to avoid hitting me all while driving on the expressway. Had someone accidentally hit me in the process it would’ve certainly flipped the car and I would’ve either ended up dead or in the ICU. After several minutes somehow without moving the steering wheel, I managed to just go straight and pull over. And waited for help to get back safely slowly. I thought the incident was isolated because the roads might have been the cause. But I went out out of the country and upon coming back, drove my car again on the expressway coming back home and the exact same thing happened with my minor child in the car across two expressway lanes in the evening time With the roads perfectly dry. Lost control of the steering wheel could not steer or direct the car and had to jerk it from to prevent it from driving off the highway. It seemed to have occurred both times at a higher velocity on expressways when the steering wheel needed to be engaged. I had it towed to the Mercedes Benz Of Coral Gables deal

Loss of Steering Control at Highway Speeds – 2022 Mercedes-Benz GLC300 Vehicle: 2022 Mercedes-Benz GLC300, VIN [XXX] Dates of Incident: September 13th and October 4th Mileage at Time of Incident: 39,500 While driving on a four-lane expressway at highway speeds, my vehicle suddenly and completely lost steering control, resulting in a total inability to steer. First Incident The first event occurred during light rain with mildly wet road conditions. Without warning, the vehicle hydroplaned and violently crossed all four lanes approximately 20–25 times, narrowly avoiding collisions with other vehicles and medians. The steering wheel was completely unresponsive. After several minutes, the car inexplicably corrected its course. Second Incident The second incident occurred weeks later under clear, dry conditions with my minor child in the car. Once again, the steering wheel locked, leaving me unable to direct the vehicle. I had to physically force the wheel to prevent the car from leaving the highway. Investigation The car was towed to Mercedes-Benz of Coral Gables, where technicians were unable to find any fault despite multiple diagnostic attempts. I have since discovered that 2023 and 2024 models of this same vehicle are under active recall for a similar steering malfunction, which may indicate that 2022 models are also affected.

Defect Summary: Since 2024, my 2022 Mercedes-Benz GLC300 has had a persistent, abnormal engine noise consistent with the sound of a 4-cylinder diesel engine, despite being gasoline-powered. The noise occurs both while idling and in motion. On several occasions, the coolant warning light illuminated while the noise persisted. The defect has worsened over time, becoming louder and more frequent. Events & Safety Risks: The dealership repeatedly claimed “no problem found” because no warning lights appeared and no scanner codes were present, ignoring my time-stamped video evidence. At one point, I was advised to drive the vehicle from Morgan Hill, CA to the dealership while making the loud noise for diagnostics — an unsafe recommendation. When the coolant warning light appeared, the service department planned only to top off coolant. I insisted on a diagnostic, which revealed a coolant hose leak. Driving with a leak could cause overheating and sudden engine failure, creating a serious safety hazard for myself, my child, and other motorists. Repair History: Multiple visits to Mercedes-Benz of San Jose (2024–2025) for the same defect. Each time, the defect was dismissed or not resolved. No meaningful repairs were performed. The issue persists today. Evidence: Time-stamped video proof of defect, full service records, and documentation of correspondence with the dealership are available. Safety Concern: This unresolved defect creates a risk of sudden engine failure or overheating whil

My 2022 Mercedes-Benz GLC 300 has been diagnosed with a valve seat failure. This requires a full cylinder head replacement. I purchased this vehicle brand new and have driven it with care, putting approximately 60,000 mostly highway miles on it. Throughout my ownership, I have exclusively used the service at an authorized Mercedes-Benz dealership. Despite my efforts to maintain this vehicle properly, the vehicle began exhibiting misfire issues just outside of the warranty period. The check engine light would flash on and off during a misfire and it presented multiple codes. I returned to a Mercedes-Benz dealership, where I was told the issue is an internal mechanical failure, worn or leaking valve seats requiring full cylinder head replacement with an estimated repair cost of $7,800. Upon researching this issue, I've learned that Technical Service Bulletins exist for this exact failure, and other owners with M264-series engines have experienced identical symptoms and failures. This misfire could happen at anytime, requiring me to stop the vehicle almost immediately. It could cause a dangerous situation in heavy traffic areas with fast moving traffic.

I took it to the dealer for repair and the fuel tank sensor was replaced under warranty a month ago. Now, this week the same issue reappeared. The car began showing no gas in the tank on a random morning last week and remained driveable for a couple of days. The gas levels reappeared corrected on day #3.

Attempting to get recall completed but manufacturer and dealer are non-responsive. Mercedes stated that if a failure occurs life and limb are at risk (slightly paraphrased). Mercedes says in the recall notice that the repair will take 1-6 hours. Scheduled for a Friday and the Service Advisor sent confirmation and at least one appointment confirmation. At the shop by 8am. Service Advisor immediately tells me that the repair will take two days. It is a Friday. Means they will keep the vehicle through Monday. Thought a Service Advisor whose jobs are service and advising would perhaps called and maybe suggest rescheduling for other than a Friday so we would not be short a vehicle for four days. Or maybe, as the Sales guy promised us, have a loaner for times we would be without a vehicle for extended periods. Another Service Advisor, overhearing the conversation, intervened. Seems Service Advisor Number 1 might have been incorrect, suggesting that he had limited knowledge of the vehicle he was advising about. Service Advisor Number 2 said that the issue with this model could be completed faster. So Service Advisor 1 talks to the technician in the shop and comes back and says it probably can be done in a day. Probably. Not within the 1-6 hours stated in the Mercedes recall notice. I declined. Had already been burned with same vehicle unnecessarily kept overnight before, and this was a Friday so risk was losing the vehicle for four days. Asked that he call me to reschedule when loan

Mientras el vehiculo se encuentra en la carretera comienza a dar un fallo (halones y vibracion) y pierde la fuerza (velocidad) provocando la desaceleracion. Las luces en el panel se encienden y es necesario salirse de la via de rodaje inmediatamente para estacionarlo. Esto pone en riesgo la seguridad de los ocupantes del vehiculo y de los ocupantes de los demas vehiculos, ya que al desaclerarse repentinamente puede provocar que el vehiculo sea impactado por otro. Si nos encontramos entrando a otra carretera, que requiera hacerlo rapidamente, baja la velocidad y puede provocar ser impactado.

Vehicle loses power, my vehicle stop on the highway going 55 miles per hour, I came very close to being rear ended. My vehicle consumes excessive fuel, the vehicle quicks back upon acceleration. This causes a great concern as I used my vehicle for work. I attempted to have the dealer resolve this and I was told that there was nothing they could do. However, this faulty performance might cause a traffic accident and I could also involve the life of myself or another individual in the vicinity of my vehicle. The vehicle also has a late start which is also a problem while driving. I do not feel safe driving this vehicle as I fear for my life and the life of others.

Forward Collision Avoidance › Automatic Emergency BrakingCrash
Filed Aug 13, 2023PA

I was driving on driver assistance mode. Instead of following the curve to my left-hand side, the car drove off the road and hit a power line pole on the passenger side. The car was totally destroyed. I reported to the company and asked for an investigation about the incident, but I was told that they couldn’t get the car and investigate it. I think for the driver assistance function, similar to autopilot function, the company should have remote monitoring and collect the data automatically in order to make sure and improve its safety and reliability.

Reading this record

1 death reported in complaints filed with NHTSA.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
