Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Rear view camera is not working. Frozen. I was pulling into the garage. I had to back up so put the car in reverse and then switch to drive forward and the camera froze.”
NHTSA complaint #11402593, filed 2021-03, 50,000 miles“In addition to a strong, noxious, moldy odor, vehicle's front windshield fogs over so totally that it becomes dangerous in highway driving. The HVAC/climate-control system's defroster is unable to clear more than the bottom few inches of the windshield: the only way I can see through it is to wipe away the fog with my hand. This happens when the vehicle is in motion but persists when it is stationary. This happens in almost any weather, but especially if there is moisture in the air(fog, rain).”
NHTSA complaint #11165891, filed 2019-01, 25,000 miles“I was driving down the freeway at approximately 65 MPH and the panoramic sunroof on my mercedes C300 exploded. I say exploded because nothing struck the glass and most of the glass blew out and off the car, not in. The sunroof was closed at the time, so there was no wind pressure. After I stopped, you can even see where the glass remaining is sticking up, not down. The shade was open so glass did fall into my car, cutting my arm. If kids or others were in the car, it would likely have cut them or could have resulted in glass dust in their eyes, etc. …”
NHTSA complaint #11047852, filed 2017-11, 17,000 miles“On october 15, 2019 and on july 1, 2020 the glass panel which is located in front of the panoramic sunroof blew off the car while driving on the highway. This piece of glass does not move and became a dangerous projectile endangering other vehicles. I would guess the glue is not bonding properly”
NHTSA complaint #11337594, filed 2020-07, 35,012 miles“When traveling at speed over 65 , car will begin shaking violently and hesitation occurs. This is erratic-3 instances. Terrifying!
