2022 MERCEDES-BENZ GLC 300 Complaints

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.

While driving on the [XXX] at the speed of 10 to 15miles per hour, I noticed a smoke in the from hood on the passenger side. I felt a danger and stopped the car and got out of the car immediately along with my friend, leaving my belongings phone and other documents etc. Immediately it caught up the fire. I called 911 and reported the incident. Police and Fire engine arrived and tried to stop the fire. I have sent out an email to the dealership as the vehicle is under guaranty and i haven't got any courtesy call to know about the incident. When i tried to call them they didn't even respond to me and hung the phone. I received a call from their sales department and enquiring about if i'm looking for any other vehicle which disappointed me more. I'm in shock and would like this to be investigated as this major security concern. Here is the case# i have logged with manufacturer(Mercedes) Case#:[XXX] CASE#:[XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Safety was at risk when the gears switched to neutral while I was driving in car with my children. A recall was completed when bought car was not aware of fuel pumps recall issue. Says completed repair but the car is still having issues and was sold to me without telling me about the recall. First appeared about a week ago. Making a ticking noise, losing power when accelerating.

The contact owns a 2022 Mercedes-Benz GLC300. The contact stated while driving 76 MPH, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended.

The contact stated that a warning light illuminated indicating do not shift the gear, contact the dealer. In addition, the contact stated that the gear shifter seized, and the wheels locked up. The contact stated that the failure occurred while driving on a major highway. The vehicle was towed to the dealer. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The contact stated that the vehicle was serviced at the dealer in July 2024. The contact stated that several unknown repairs were completed. The manufacturer was not made aware of the failure.

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.

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.

After fuel pump recall replacement, engine stopped on the highway with OBD message of low fuel pressure.

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.
