2020 MERCEDES-BENZ GLE 350 Complaints
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.;
2020 MERCEDES-BENZ GLE 450 Complaints
My vehicle was in for a normal service to have the spark plugs replaced. However I was told that the engine wiring harness had become brittle (apparently a common and reoccurring problem with my vehicle) and would likely cause misfiring after changing spark plugs. This did indeed happen and if I didn’t elect to have the harness replaced, it would have put myself and my son in danger. It was a very costly repair (over $4000) for something that the vehicle manufacturer is at fault for.;

2020 MERCEDES-BENZ GLS 580 4MATIC Complaints
The fuel rail system failed on the passenger side of the engine and leaks. This is the same issue seen on, but VIN number isn't apart of it: Campaign No. : 2022030003 CA DMV. : 220303 NHTSA ID 21V961 I have taken the vehicle to a Mercedes dealer twice for the concern of smelling gas. The second time I had a video but the service tech couldn't replicate the leak. This safety concern pose a great risk as the gas could come into contact with a hot surface and ignite but passenger at HIGH risk. The problem has taken to the dealer twice with video showing the leak., however they cannot reproduced confirmed/replicate it. No the vehicle or component has not been inspected by the police, insurance representatives or others? But has been taken to the dealership, not the manufacturer. No warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?Just when it leaks there is a strong gas smell as well as a visual of where the leak is coming from.;
