Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“We were driving on normal freeway speed along interstate 5 south approaching fort tejon towards los angeles when suddenly the dashboard displayed the message inoperative. Check operator's manual . With this message, the car slowed down and ultimately shut off its power on us. Fortunately, we were able to safely glide and drive the vehicle to the roadside. With the speeding trailer trucks and cars on all three lanes that we had to pass through before safely parking the car, it could have cost us our lives. Please open an investigation to address any defect on this type of vehicle. Thank you.”

“My car goes abruptly into park while driving or reversing at 5 mph or less. This is a big safety concern if it ever suddenly stalls in a highway, I may get into a life threatening accident. There are no warning or sensor lights that light up when this happens. I have taken it to the Mercedes Benz dealer who said it was a shift module error which I paid to fix and not even two weeks later the same problem persisted.”
