2023 Mercedes-Benz GLC-Class Body & Structure Problems

The glass panel between the windshield and the sun roof shattered spontaneously

The rear door randomly closes with force unexpectantly. We contacted the Mercedes dealer where the car was purchased and is serviced. They responded it can not be fixed and was an ongoing concern of many owners

The contact owns a 2023 Mercedes-Benz GLC300. The contact stated that while the vehicle was parked, and the contact and his wife were removing groceries from the rear of the vehicle, the tailgate was independently lifted due to the design of the keyless entry feature. The contact and his wife continued to remove items from the rear of the vehicle and the tailgate sensor became enabled, and the tailgate closed inadvertently, striking the contact's wife on the head. The contact's wife sustained a knot on the head that remained for a week. The vehicle was taken to the dealer. The contact was informed that the feature could not be deactivated unless the contact chose to deactivate the entire keyless sensor feature. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and the contact was informed that the option would be to deactivate the entire keyless sensor. The failure mileage was approximately 1,000.

1. The rear hatch has opened while the car was left unattended. 2. If the hatch opens it could possibly cause a safety issue: a.By opening while driving. This has not happened and I do not know if Mercedes has a safety lock to ensure this could not happen. b.Open while parked and unattended. The vehicle would be unsecured with items being subjected to being stolen. c.Open while parked at the store, mall, etc. A stranger could get in the rear of the vehicle, close the hatch and wait for me to return causing a dangerous situation. d.Open and damage the garage door if parked in the garage; e.Open while someone is in the back of the vehicle. Should this happen, a person could be pinned against another vehicle or garage door. 3.Mercedes Benz is aware of this issue on many of their vehicles. I was told the S class Mercedes has had a similar problem and Mercedes reprogrammed the key fob to a “2X push of the rear hatch button on the key fob”. They have yet to do this on my vehicle. 4.The vehicle has not been inspected by Mercedes, however, in discussing this with the Mercedes Service Department they are aware of this issue and as of today there is not a similar fix as to that of the S class Mercedes. Mercedes is aware of this problem but has yet to offer a fix. Also, upon doing an internet search, I have discovered others having experienced similar problems over the course of many years. 5.There were no warning lamps, messages, or other symptoms relating to the problem. This problem first appeared within a few miles of owning the vehicle. The vehicle is currently has about 1,100 miles.
