POWER TRAIN, STEERING
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

ENGINE
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

FUEL/PROPULSION SYSTEM
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 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.

FUEL/PROPULSION SYSTEM
Gasoline 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.

ELECTRICAL SYSTEM
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 safety risk.

SEATS
The 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.

BACK OVER PREVENTION: WARNINGS, WHEELS
There 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.

UNKNOWN OR OTHER
My 2015GLK 350 shifts into an Automatic P (Parking) while driving under 6 miles per hour. When shutting the car off and immediately starting, the transmission automatically performs another Automatic P (and puts the car into Park) when driving under 6 miles an hour. This puts myself and other drivers at risk. The failure first appeared 60 days after purchase of this vehicle (first happened in August 2021). I took the car in to the independent repair shop in Long Island, NY in Nov 2021. I've had the car looked at and by an independent repair shop and they could not immediately identify the issue. No warnings lights or sounds went off before the automatic p (park) happened. The independent dealer did some research and referred me to an alert from 3/2015 *Topic number LI54.25-P-056472 Version 3 *Key in Electronic Ignition switch (EZS) is not recognized, automatic transmission shifts to Park before vehicle comes to a stop! Cause - An assembly issue I am wiling to get the car repaired, just wanted help with Good Will Assistance from Mercedes Benz, because he cause of this issue is assembly related and my VIN falls under the alert/assembly issue.

FUEL/PROPULSION SYSTEM
2020050005-Modificationto emission control system cause:F Was informed of the Mercedes-Benz Recall for 2015 250 GLK BlueTec which I took to Dothan, AL Mercedes-Benz Dealership to have done for my safety. The car was not repaired correctly. It started to smoke a gray smoke coming up from under the car on the passenger side of the car over the front tire. I do have pictures. It smells as if it is about to catch on fire. The car never had any problems before this botched repair. Now they say they cannot find the problem. I’m afraid to drive it until they do. Each time they return it, the smoke is worse.

POWER TRAIN, ELECTRICAL SYSTEM
My car goes abruptly into park while driving or reversing at 5 mph or less. This is a big safety concern if it ever suddenly stalls in a highway, I may get into a life threatening accident. There are no warning or sensor lights that light up when this happens. I have taken it to the Mercedes Benz dealer who said it was a shift module error which I paid to fix and not even two weeks later the same problem persisted.
