Example complaints

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

“Normal clear weather driving down busy street when care suddenly slowed down almost resulting in a collision with vehicles behind me. The engine stopped , I restarted with very limited drivability the etc failsafe mode kicked in for no apparent reason this issue must be addressed before someone is seriously injured.”

NHTSA complaint #10820770, filed 2016-01, 105,000 miles

“Brand new battery in car. Come out to start car. Battery is dead. My mechanic has car for three days. He tried to find a short. He instructed me to make sure all doors are completely closed and lights are all out. This was after multiple dead batteries. I made sure of all the above and still came out to dead batteries. I manually turn off the lights as I came out to them being on after I had watched them dim and go out. I replaced the new battery with another new battery and I am still having problems.”
