SUSPENSION
When attempting to rise/lower the automatic suspension, the compressor cooling notification pops up, followed by a malfunction. After this occurs, the vehicle is incredibly bumpy, to the point of it being unsafe to drive. The vehicle has been repaired twice already by the dealership under extended warranty and the condition has occurred a third time in less than three weeks. This is our family vehicle, and we cannot drive it due to the risk of shaken baby syndrome for our infant because of how much it bumps. Videos are available to show just how bad it is.

SEATS
Third row seat will not lock. Warning message came on several months ago. I brought the vehicle in for service in may of 2022 to Mercedes Benz of Westwood MA. They neglected to repair the issue with the seat and returned the car back to me with the safety issue still unresolved. I spoke with the dealer and Mercedes Benz USA and they refuse to repair the vehicle under warranty even though it was still covered under the factory warranty. [XXX], the service manager at the dealership informed me that the third row seat motor needs to be replaced in order for the seat to lock. He said it is a very common problem with my model vehicle and that is the reason why the manufacturer wont cover the cost of repairing this safety issue. The dealer says the cost for this repair is 1750.00. We are worried that if we have a passenger in the third row seat, they may be injured due to seat not locking. I believe this is a widespread safety issue and I believe it should be covered under a voluntary recall. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

While driving our 2018 Mercedes GLS 450 down Highway 80 just outside Sacramento, CA, the stationary glass panel of our panoramic sunroof spontaneously explpoded. There was no impact by any outside force, it just shattered with the sound similar to a gunshot. Fortunately I did not lose control of the vehicle, and thankfully the sun shade was closed otherwise broken glass would have showered down into my vehicle. this happened in early evening (around 7:00PM and the ambient temperature was 66 degrees outside, so this had nothing to do with temperature either. Mercedes Benz told me that since I am 3 months outside of warranty they would do nothing to help us and I would need to have this repair done on my own. Mercedes Benz of Walnut Creek, CA has inspected the vehicle and we're in the process of having the claim approved through my insurance. Completely unacceptable that this would happen on this (or any other vehicle). There is a class-action lawsuit against Mercedes for this exact same problem across a number of their models, so this is not an isolated incident. Had my wife been driving, she could have been startled to the point of losing control of the vehicle, possibly causing serious injury or death.
