I am reporting a serious safety defect in my 2019 Mercedes-Benz GLS450. My vehicle experienced low oil pressure warnings and engine warning lights, which were diagnosed as a faulty oil pump solenoid valve.

If the sunroof shade would have been open, the glass would have came down the drivers and passengers as they were going down the road. Saying this was distracting is an understatement. I called the local Mercedes dealership and was completely dismissed by them. They said it would have to be repaired by a glass …
