2019 MERCEDES-BENZ E 450 Complaints

My tempered glass sunroof exploded while driving at 70 MPH on a clear, sunny, 86 degree afternoon sending the glass shards throughout the interior of the car. No warning or damage to the vehicle roof preceded the explosion. There was a very loud noise followed by the safety glass raining down on myself and my wife. It occurred while driving on the expressway and no other vehicles were involved. There are only glass fragments for inspection and I will take it to the dealer in the morning. I have pictures of the aftermath if requested.

The car will apply electronic parking brake when put into park. If the brake is wet due to rain and the car sits overnight or for 12 hours or more, the brake sticks to the rotor. The brake will not release unless you press down on the accelerator creating a safety hazard as the car will jerk forward or in reverse. I've raised this with the MB dealer and service technician and they confirm the this Amy happen and that there is no fix. This situation creates a serious hazard.

The contact owns a 2019 Mercedes-Benz E450. The contact stated while driving at various speeds and depressing the accelerator pedal, the vehicle hesitated while responding. Additionally, the contact stated that the transmission was slipping. The check engine warning light was illuminated. The contact stated that upon taking the vehicle to an unknown dealer, the check engine warning light turned on while the dealer was moving the vehicle into a parking space. The vehicle was taken to the dealer several times however, the dealer diagnosed that no issues were found. The vehicle was taken to a second unknown dealer, where it was diagnosed that the battery needed to be replaced. The battery was replaced, and the oil change was completed; however, the failure persisted. The contact stated that the vehicle had been failing the Emissions test and she was informed at the State Inspection that the camshaft positioning sensor on the cylinder #1 and #2 were malfunctioning. Additionally, the contact was informed that the data in the instrument cluster and the Head-up Display (HUD) had been malfunctioning. The contact was informed of other unknown failures. The contact also stated that the vehicle started independently. The contact stated that the vehicle had accelerated unintendedly while the transmission was slipping. The manufacturer was notified of the failure through mail, but no assistance was provided. The vehicle was not repaired. The failure mileage was approximately 20,000.

Central digital driver cluster and lighting behind all speedo/tachometer randomly turns off while driving unexpectedly then fades back on. - can not see control indicators for adaptive cruise control when display fades out - can not see what gear the transmission is in when display fades out - at night can not see speedo, tach, or any items on the display when it fades out Dealership said they could not duplicate and didn't want to replace the cluster, because they have to send the part back to mercedes engineering and if the part wasn't faulty, the dealership would have to absorb the cost of repair. This happens every time I drive the car. Contacted Mercedes USA customer service and they have not been responsive.
