“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?!?! …”

“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.”

“I own a 2016 Fiat 500X, unsure of the model because I was told I was purchasing a trekking but paperwork states lounge 2. The VIN number has brought up the different two models depending on what VIN search you use. One issue with the vehicle, are the exterior lights. At the current time, it has a blinker, rear taillight and a brake light out. And when one light goes out, usually 2-3 other lights follow. This will be the 3rd time it's going in for repairs for that electrical issue. It is also consuming too much oil. …”

“I have had at least 5 incidents so far with my Fiat turning completely off while driving down the road. I have taken it in numerous of times to the dealer with no luck. I have documented each and every time my car decides to shut off while driving. I find my car to be a safety hazard to me and my family as well as others. The dealerships seem to not know why my Fiat tends to shut down while driving. First I had only about 25000 miles and it shuts off while turning in a 4 way intersection, Fiat place had me take it in just to say it needed an update. …”

“Around october 9, I tried to turn on the ignition as usual with the key fob. The engine would't turn, so I recharged the battery. After 10 minutes, it finally cranked. The battery is good, however, so I replaced the battery in the fob. On october 19, I used the key fob and all kinds of indicator lights came on. When I placed the car in reverse, several light indicators (service engine, check transmission, etc.) and it was like something inside the engine dropped as if the car shifted into another gear. The 'r' and the 'd' blinked steadily. …”
