Example complaints

“Takata recall my vehicle brake got stuck while I was driving on the highway. The car also released a gas/oil odor when the car has been running. The car has also been having problems to start need to attempt to turn on vehicle twice before it actually starts. Brakes have malfunctioned multiple times already and could have caused an accident.”

NHTSA complaint #11231184, filed 2019-07, 18,000 miles

“Passenger seat air bag indicator flashes and warning sound indicates seat belt is not buckled when nobody is in the seat. When accelerating, there are multiple hesitations where the car feels like it is in park or neutral. After about 15-30 seconds, the car starts accelerating normally”

NHTSA complaint #11230197, filed 2019-07, 9,900 miles

“When refueling the vehicle, and placing the nozzle into the gas refill port, the gas will cut off as if the tank is full. Only when the gas nozzle is inserted 3/4 of the way into the gas refill port will the gas flow uninterrupted.”

NHTSA complaint #11129837, filed 2018-09, 150 miles

“When I put the nozzle to pump gas, the pump shuts off and clicks as if the tank is full. I have to twist the pump in one specific position and place it about 3/4th of the way in. Sometimes I have had to leave and go to a different gas station if the accordian plastic part of the nozzle is long. It just clicks and shuts off the pump. This happened from the day I first got the car, got gas and never ceases.”

NHTSA complaint #11446741, filed 2022-01

“UNKNOWN - for the past several months, since my car hit the 70,000 mileage mark, my check engine light has come on while experiencing hard idling, delayed acceleration/power while driving - particularly on gradual inclines and hilly roads. I would suspect it has something to do with the power or fuel system. I have changed oil twice and had a diagnostic test done and mechanic is unable to pinpoint issue since it is not consistent.”
