Example complaints

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

“Since about 60,000 miles, the car it stalls out. It can stall going 70 MPH down the interstate, stall at stop signs, stall pulling out of an intersection. Last occurrence I was trying to cross a major highway when it stalled. I coasted across the highway and it restarted right away. If a car had been coming from either direction, we would have been hit. I have had 4 sensors replaced and nothing seems to fix this problem.”

“Took my car into firestone and found out that the motor mounts are sagging. Most cars only need the bolts on the mounts replace - the Lucerne is the only one where you need to replace all the motor mounts because they don't have bolts in them. Another few miles and I will have an engine sitting on the highway. I am extremely upset because my husband is already handicapped and we bought this vehicle to last for more than 150,00 miles before we had to sink that kind of money in it. I have had a second opinion and it is indeed a problem.”
