“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 GLE 350 first displayed a problem with left indicator on front left hand head lamp. I took an appointment with my Mercedes dealer for repair.

I parked it in my garage, shut off the engine, locked it and in a couple minutes, it started a blower like sound. I called Mercedes service center and described the problem. They sent a tow truck. …”

I told them I would complete a report to the NHTSA and he seemed very unconcerned. …”
