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
NHTSA complaint 11731078Any time a passenger sits in the passenger seat in the shows on my dashboard “ front right malfunction service required “
NHTSA complaint 11711749My 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 sitting since Saturday without being turned on and the gas spot on the ground remains wet. It’s very dangerous and right now I cannot fix it due to finances.
NHTSA complaint 11627422Gasoline smell around the car when parked in the garage. An inspection underneath the car and in the engine, bay failed to locate the leak. 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 support as I thought that they may have been a campaign to replace this component since the 2012 GLK had a recall for fuel flange cracks but the MB customer support team indicated that a campaign did not exist for this issue on the 2015 MB GLK. Since the car is out of warranty, I purchased a replacement part 2184700994 and installed it which fixed the problem.

NHTSA complaint 11607406Key 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 safety risk.

NHTSA complaint 11606711The leather seat on the drivers side has melted. After trying to research for a recall, I did see that others have had this problem also. It appears that the seat heater causes the leather to melt. The leather has melted and peeled and is flaking.
NHTSA complaint 11597950There are two issues with my vehicle, both started recently. The mileage is only around 33000 miles. The two front tire pressure warnings keep coming on, and I have tried multiple times to correct this, doesn't matter if it exactly correct on reading for pump, or above or below, it just keeps saying they need adjusting. It is only the two front ones and they have been doing this for about 2 weeks now. Second issue has been a recall for other mercedes models but not mine, and it could be that there are much fewer of these on the road and had less complaints. It is exactly same issue that other models that have been recalled. My reversing camera has started to either not work at all, or come on and go off, then reset and come back on again, however this is making it impossible to rely on in a reversing situation. It is basically dangerous as I can be halfway into a manoever and it stops working.
