“While I am driving my car it will make a loud crackling sound then my screens go black and warning sounds go off! This is not normal and I read there are recalls but when I entered my vin# nothing came up. Not to mention since I bought the car last February, I have had nothing but issues with my AC turning off which that I have taken to the dealership with video proof and told it was a software update which did not fix the issue. i am paying way too much money for a newer vehicle and having more issues than my 2015 Mercedes Cla 250.”Owner report · Electrical System · Jul 2026
“The driver's seat in my car moves backward on its own while I'm driving. I've taken the car to the dealership several times, but the issue still hasn't been resolved. This is extremely dangerous and frightening. It has happened twice on the highway, Several times in the dealership's garage, And most recently, while I was pulling out of a parking spot: Half of my car was still in the parking area and the other half was already in the street. The road had a curve, so other drivers couldn't see me until they got very close, which could have caused a serious accident. This is a serious safety concern that needs immediate attention.”Owner report · Seats · Jul 2025
“I was driving and all of a sudden a loud sound started occurring and the sound appeared to come from my breaks as if they were about to give out. The car is currently at Mercedes getting looked at. I'm concerned for my safety as I have taken this car in for two other issues in the last couple of months.”Owner report · Service Brakes · Jun 2024
