The Panoramic Sunroof Glass front cover has detached three times from my 2017 CLA 250 (VIN#[XXX]). The first time that it detached was with the previous owner and was repaired at a Mercedes dealership in Tampa Florida. It has since detached twice with ME and I have only owned it for 12 months. The first time that it detached with me, I was driving approximately 60 MPH on I-85 in Montgomery. AL. It blew off and could have definitely caused a VERY SERIOUS accident, but luckily no vehicles were behind me at the time 4/29/21. So I went to the local Montgomery, AL.

I was driving on the toll road when out of no where I here a loud boom and crackle above my head. Almost like a firework when it goes off. I thought it was a gun shot. When I looked up my panoramic sunroof was gone. Nothing was driving in front of or beside me. Nothing hit my car. However Mercedes says it's impossible and something hit it, but my insurance won't pay for the sunroof repair because of class action lawsuits. They say it is Mercedes responsibility. However, Mercedes basically called me a liar and refuses to replace the panoramic sunroof. They want to charge me $3200 to repair it.

Hello, My 2017 CLA Mercedes was recalled April 1 2021. They said its a hole in the steering shaft and it can lead to noises and crash! Its been over 3 months and the manufacturer has not fixed my car. Everytime I call they don't have an update on when it's going to be fixed. I have my family who I drive around in this car and I'm worried the steering might cause harm to us. We need assistance in getting this resolved. Thanks

Safety Risk: The failure of the partial-load ventilation valve put my safety, and that of others, at risk in the following ways: •Engine stalling or reduced power while driving, especially during acceleration, which increases the risk of an accident. •In some cases, oil leakage caused by excess crankcase pressure could lead to
