Advanced corrosion could weaken the screws, leading to potential breakage during manoeuvring or parking. If all fixing screws fail, the power-assisted steering could detach, resulting in a loss of power steering and an increased risk of an accident.

If a gas generator ruptures, the airbag would then have no restraining function and loose parts from the gas generator could reach the vehicle interior. This would increase the risk of injury for passengers.

Hello. Since I bought this car in 2015. Every now and again it will go into park when driving and tge car will stop suddenly. It has done it a few times over the years and it’s quite scary. Mercedes has put me off on you, without addressing the situation or looking at the car, unless I pay first it. I think there is a mechanical defect on this car and it is quite dangerous
Any time a passenger sits in the passenger seat in the shows on my dashboard “ front right malfunction service required “
The steering adjustment moves in and out but will not move up or down. You can hear a clicking noise like it’s trying to move but nothing happens to the steering column.
The DEF exhaust system has failed. It was replaced before under a recall. The warranty was previously extended on the system but I am outside of the mileage window but inside of the time window. I have $6000 in repairs so far and am trying to get assistance. I have been dealing with issues since October 2024
My truck has been smelling like gas for a while. I replaced the gas cap and still smelled gas when I was driving. Recently I started smelling it inside the car. It was leaking from two places under the car when I would drive it or just have it running. The mechanic took the plastic piece off the bottom and gas started pouring down. He took the back seats out and there was a pool of gas sitting on the fuel pump. He had me start the car and it immediately started spewing from the fuel pump inside the car. I did not know I could report a complaint so I did not take pictures. The car has been…

A [XXX] search for fuel leak on Mercedes Benz (MB) returned a number of hits for problems with leaks around fuel tank components on the GLK and other MB models. Upon removal of the rear seat and a check under the two fuel tank covers, I found gasoline pooled on a concave area on top of the Fuel Suction Pump Assembly, MB, part 2184700994 (see attached photos). This plastic part has cracks in it that allow fuel to escape. I contacted MB U.S. headquarters…
Key in electronic ignition switch is not recognized, automatic transmission shifts to automatic park before vehicle comes to a stop. When car slows to 5 miles per hour it abruptly slams into park, putting myself in danger of being rear ended in no fault of my own. It happened multiple times before I could get my vehicle to safety. This has been a known issue as documented on website [XXX] in a memo from Mercedes Benz dated 12/22/13 service memo [XXX]. This is two years prior to my model automobile and should have been rectified. This should have been addressed as a recall item as it is a known…
The lien keeping assistant is stuck in operative mode. So I had a recall on my airbag and got it changed out yesterday and had the dealership check why it was on they told me I need a new steering wheel. Prior to yesterday two months ago.
