Example complaints

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

“)n 6/15/20 while driving to a doctors appointment on the highway, my engine suddenly overheated and it warned me to pull over immediately. The vehicle had 37,800 miles on it. On diagnosis, it was found that a valve in the water pump had seized from a coolant leak, preventing it from opening and circulating coolant into the engine. Unfortunately, the car was just out of warranty.,”

“If something in the roadway hits the oil pan it will crack and causing the engine to lock up without notice. It seems there should be something protecting the oil pan preventing this from happening and more time notifying of low oil should be allowed to move off the road way and shut the engine down. I also question the strength of the material or design of the oil pan.”

“There was an issue with the water pump, mb has since replaced the product with a new one because of issues with the old style not working. My car is just over the warranty and has on 10,270 miles on it and is now experiencing the overheating issue (warranty ended december 2018). If the problem with old style water pump was known why not notify customers? When the vehicle is on, driving or running stationary the engine overheats.”

“Immediately after entering a freeway from an on-ramp at approximately 60mph, warning chimes for collision indicator deactivated came on, auto-dampening of engine speed occurred, and auto-braking occurred. No vehicles were directly in front of vehicle, nor near enough to side or rear cause proximity sensors to activate. The only remedy for this was to limp to the side of the road (in rush hour traffic), turn off car, and then turn back on. All indicators and warnings were cleared upon restarting vehicle. This is the second time this has happened within 12-months.”
