Example complaints

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

“Car will randomly turn itself off while driving. This has happened 3 times (I currently have just over 70k miles on the car). There are also electrical issues (seizure warning should come with this car- the touch screen radio will turn itself off and on continuously while driving). As with most other complaints, my drivers side door handle came off as well.”

NHTSA complaint #11362373, filed 2020-10, 60,000 miles

“During a normal driving conditions a couple weeks ago, my Fiat 500X's engine turned off / stalled while I was driving. I was in the city and getting ready to turn, so I was at a slow speed - around 8 MPH. I had to turn the car off and on again and it seemed to be fine after that. But this was very alarming and if I had been going a higher speed, it could have been very dangerous.”

“Transmission kicks from first to second at take off after stops. Usually traffic lights. I have taken the car in for service twice, the kick doesn't happen all the time anymore, but it still happens. It's a concern since I've almost been rear ended twice.”

“Happened again -- this is the third time this has happened since I purchased the car in nov 2016. Engine shuts off while driving. Fiat dealer apparently clueless about the issue and how to repair. Took car to same dealer all three times this happened - each time they've given me a ridiculous reason the car is literally shutting off while I am driving down the street!! First time they said it was because the computer needed updating?!?! …”

NHTSA complaint #11128027, filed 2018-09, 30,000 miles

“Over the past two years I've had to take my vehicle in to the dealership numerous times. The car will accelerate on its own without touching the gas pedal, switch gears on its own, accelerate while making a stop, uncontrollably jerk well moving at a slow speed's and display messages such as drive mode unavailable at random times while driving. This car is dangerous to drive and has almost created an accident numerous times while I had my children in the vehicle.”
