Example complaints

“While driving in a parking lot at a low speed my car turned off by itself I kept pushing on the accelerator but I realized the car is not moving, it had shot off by itself. I turned the car on manually and then worked. It was a terrifying situation. I kept thinking what if I was on the freeway and my car had turned off while the moving traffic was about 70 miles. I contacted mercedez bez and I was told it might have been a glich and that they could not duplicate it. I feel that is a very dangerous glich.”

“I keep getting coolant level low. I add coolant fluid into the tank and the warning message comes up again. I see no leaks under my vehicle so not sure if there’s a leak inside the tank itself or air leak somewhere but I’ve gotten that warning message about 10 or more times. Also as im driving the blind spot sensor just randomly goes off without a car or anything being next to me.”

“My 2020 Mercedes-Benz GLE 350 experienced a complete engine seizure at approximately 60,000 miles without any warning signs. The vehicle shut down and would not restart. The engine is completely inoperable. I am aware of recalls involving engine stalling and fuel system issues in this model, and I believe this may be related to a broader defect. Mercedes-Benz has not offered support as of this writing.”

“As many other GLE 350 owners reported on various forums, same thing happened to me. My car suddenly started shaking and some cylinders misfiring. My car is just 2020 and barely got 60,000 miles on it. Initial report shows that two cylinders misfires with no reason. It's failing the emission and car will not pass emission test anymore. Mercedes says it's out of warranty and asking 15k to replace cylinder head.”

“We were traveling to our son’s college graduation, driving on a rural interstate and suddenly all of the vehicle’s warning lights lit on the dash and the car started losing, and then completely lost power. The car was no longer operational. We were stranded on the roadside of a remote but busy 2-lane interstate for 2 hours until a tow truck could arrive and take the car to the closest car repair shop which was 45 minutes away. …”
