STEERING
10 complaints
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 dealership, but they cannot find anything wrong with the car, even though the exact same model of my car has an active recall for 2023 and 2024 models. For the same problem, I later learned. Mine is a 2022. I have been in a loaner vehicle for three weeks while they investigate and I need Assistance to make sure that something gets done because nothing has been found and I do not want to risk driving with my child in the car.

The vehicle's steering wheel vibrates noticibly between speeds of 47 mph and 55 mph. This issue was once addressed with a "software update" by Mercedes Benz of Portsmouth, NH. Streering wheel vibration is a concern for any driver that rely on power steering to turn or hold the car steady. In addition it creates unnecessary panic for some drivers. This issue is brought to Mercedes Benz multiple times. I had replaced all the tires at 19,000 miles, balanced, got tires aligned by Mercedes Benz dealer and the issue persists.

There is a significant steering vibration as the front wheel drops in a common pothole turning at speeds above 30 mph. There is a loss of control as if the wheel is skipping. It feels like the shock absorber continues to vibrate for a few seconds. I did mention this to Mercedes-Benz during the annual maintenance service but they did not do anything.

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." Therefore my only way to get the car repaired is to go through my insurance company. What a rip off! I totally thought Mercedes was a company that would stand by their products, especially those under not just 1 factory warranty, but a 2nd extended warranty. And, I got called a liar to boot.

The transmission intermittently shifts hard. When accelerating the car hesitates badly then lurches forward. The Dealer verified the concern, the transmission as a hard shift from 1-2nd. They performed various procedures to the hardware, but ultimately determined the problem is the software and that this is a known issue to Mercedes since early in the year. They have not been able to resolve the software issue. This creates a major safety hazard: 1. When changing lanes, the hesitation does not allow for proper acceleration creating a timing issue which could result in a collision 2. When crossing over lanes on a turn, the vehicle has stopped at a time, not accelerated and left me in the middle of oncoming traffic.

My father was driving home from golf. He was driving for about 5 minutes. He was at a red light and smoke started coming out of the car. He turned car off, then on. Smoke started getting worse. He put on the emergency blinkers, got on the sidewalk, and looked underneath the car. Within a few minutes the car blew up. There were no warning lights and the car was driving normally. Car was brand new and was about 1 year old. 2022 GLC.

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 loaner was available. He agreed. He reviewed phone numbers and said he would call by end of day. No call. I contacted Mercedes and was promised dealer was diligently working to get this done and would contact me). Five weeks have passed and no call. Not sure if intentional or incompetence but unacceptable.

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.

There is a constant acceleration failure where the car does not respond. Again today I was almost in a bad crash due to this. It is a known issue to many owners in Mercedes forums. It happens in any drive mode. Eco comfort sport. Extremely dangerous and the car should be recalled.

The contact owns a 2022 Mercedes-Benz GLC300. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. There was a misfire coming from the engine, and the vehicle lost motive power. In addition, the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed with spark plug failures, coils, and the transmission needed to be flushed. The vehicle was taken to an alternate dealer where the spark plugs and coils were replaced, and the transmission fluid was flushed. The contact stated that the failure reoccurred. The vehicle was then taken to an independent mechanic who was a Mercedes mechanic, where it was diagnosed with misfire codes in cylinders #1 and #4, leakage coming from exhaust valves in cylinders #1 and #4, low compression in cylinders #1 and #4, and there was a 75 percent leak in cylinders #1 and #4. The contact was informed that the complete head assembly needed to be replaced. The vehicle was not repaired. In addition, the contact stated that the vehicle was repaired under NHTSA Campaign Number: 23V445000 (Fuel System, Gasoline) on 11/2025. The contact stated that the failure began shortly after the recall repair was performed. The manufacturer was not made aware of the failure. The failure mileage was unknown.

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.

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.

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. Safety Concern This defect poses an imminent risk of fatal accidents, both to occupants and to other drivers. The failure occurs without warning, at high speeds, and results in total loss of steering control. Requested Action I request that the NHTSA investigate whether 2022 models should be included in the existing recall related to steering control failure in Mercedes-Benz vehicles.

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 while driving, potentially causing loss of control or stranding occupants in unsafe conditions.

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.

The car randomly shows an empty tank of gas at the start of the day, when there was a half tank of gas remaining. I filled the gas, but the car did not register any fuel-up and kept showing empty. 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. Today, 4 days later, the car went back to showing zero gas, and shut off while I was driving on an expressway with my minor child in the car. All of the lights on the dash lit up, and the car stopped. It is immovable. It could have caused a severe or fatal accident and this is totally unacceptable!! This is the third time this issue appears on a brand new car that I’ve had less than a year, with 15k miles.

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.

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.

Since I purchased this vehicle 2.5 months ago, the windshield wipers started chattering/making noise and not working properly after about 2 days. I brought the car in and the dealership replaced the wipers. The chattering started again shortly after, then the dealership polished the windshield. It worked well for about 2-3 weeks and now the wipers are starting to streak and chatter again. I have a third appointment to have the windshield re-polished and wipers replaced, again. I have no faith this will fix the issue since its been done before. I see that this is a common issue with this brand/model.

Vehicle vibrates quite violently when hit some potholes. Steering wheel is the part that vibrates more but vibration is felt throughout the vehicle. It is more prevalent at highway between 55-65 mph speed. I also noticed that car shakes unusually and tilts to one side at times making it quite uncomfortable for driver. back tires make slipping noice on potholes and feels like car is going to be unstable momentarily . All these issues are putting driver and others at risk. I joined Facebook page of glc300 owners and almost everyone reported this kind of problem. For most of the people including me , it is still unresolved . I took my vehicle to dealer and they updated software but issue still persists.

When driving at 40 to 60 MPH and hit shallow pot hole or bump in the road the front wheels violently shake and the steering wheel (electric steering) violently vibrates for 5 to 8 seconds. Dealer checked the vehicle and claims there is nothing wrong with it but did turn off the "attention assist" setting from sensitive setting claiming it was the cause. The issue still exists but not as violent. I'm concerned of loosing control of the car/my safety. FYI: never experienced this issue with my previous car (same car two years older ,2020 GLC 300).
