The contact owns a 2013 Mercedes-Benz GLK350. The contact stated while driving at 40 MPH, the headrest inadvertently deployed and hit the contact's husband in the back of the head. There were no warning lights illuminated. The contact stated that they continued to drive the vehicle and later veered to the side of the road to determine the cause of the failure. The dealer was notified of the failure and advised the contact that they would be responsible for the cost of the repair as the vehicle was out of warranty. The contact stated two months later, an unknown message appeared on the instrument panel indicating that the driver side and passenger side frontal air bags needed to be replaced. The vehicle was taken to the dealer who diagnosed that the headrest needed to be replaced. The manufacturer was notified of the failure and did not provide any assistance. The vehicle was not repaired. The approximate failure mileage was 73,930.

I have a 2013 mbz Glk350. The vehicle I own has leather seats (or they are supposed to be leather.) I have noticed, especially on the driver's side front seat, that the leather appears to have melted for some reason. I these seats were indeed leather I would have thought this would not be happening, but unfortunately, it has. I suspect that the leather seats are really a hybrid seat of synthetic materials that are prone to "melting."
