“The contact owns a 2015 Fiat 500. The contact stated that while driving at 35 MPH and attempting to downshift, the vehicle failed to respond as intended while the RPM continued to rev. There was no warning light illuminated. The contact stated that the gear shifter was significantly difficult to move up or down, causing difficulty in engaging the brake as needed. The vehicle was taken to an independent mechanic, where it was diagnosed that the manual transmission gear pin had failed and needed to be replaced. The vehicle was not repaired. The dealer was contacted and confirmed that the VIN was not included in NHTSA Campaign Numbers: 16V302000(Power Train) nor 19E044000 (Power Train). The manufacturer was not notified of the failure. The failure mileage was approximately 42,000.”

Engine

16 reports1 crash
“After bringing vehicle to a complete stop at a traffic light, it died and gave a propulsion system warning. After about 20 attempts to turn off and reboot the vehicle, it restarted and behaved as if nothing had happened. This was a very dangerous situation with the vehicle stuck in the middle of the road. There have been two recalls on this very specific issue (and this vehicle has had that related software updates). Vehicle did the exact same behavior for no reason. (NHTSA campaign: 16V303000 & 15V179000). And because the vehicle wasn't sold in Georgia, no local dealers know how to work on it.”

Fuel/propulsion system

10 reports1 crash
“I was driving our Fiat 500e (31K miles) in late June, when suddenly the HV Battery System (and primarily the PIM/Power Inverter Module that controls the HV battery system and propulsion system) failed, causing my moving vehicle to lose it's ability to use power steering. I was on a steep hill and was barely able to control the car. I contacted my local Fiat dealer, had the car towed there, and it has sat there for 3.5 months, while the dealership and Fiat USA have argued over how to repair it. In the meantime, the 8 year warranty on the HV battery system has winnowed down and will go out of warranty this month. It is my belief that Fiat USA has purposely delayed a resolution so they could not have to pay to repair the car under warranty. The PIM controls the HV system and propulsion and yet Fiat claims that the PIM is not their responsibility to repair. This is an otherwise perfect car with only 31K miles and the idea that it would be junked and sent to landfill over a bad PIM controller (a small component the size of a football) is a tragedy. Via online messaging boards, I have spoken to numerous other owners of Fiat 500e autos who have suffered a similar PIM…”

Steering

7 reports
“THE STEERING HANGS OR STICKS. IT STARTED A COUPLE YEARS AGO AND WAS REPORTED TO THE DEALER WHERE IT WAS PURCHASED. I WAS TOLD IT DOES THAT. IT STARTED DOING THIS AROUND 50 TO 70 WHEN FIRST NOTICED AND NOW DOES IT AT ALL SPEEDS. WHEN IT FIRST STARTED IT WOULD COME AND GO AWAY SLIGHTLY BUT NEVER COMPLETELY. NOW IT IS ALL THE TIME AND ANY SPEED. AT HIGHWAY SPEEDS IT MAKES THE VEHICLE STEER SLIGHTLY FROM SIDE TO SIDE IN THE LANE SINCE YOU CAN'T MAKE SLIGHT STEERING CORRECTIONS. WHEN TRYING TO MAKE STEERING CORRECTIONS THE STEERING WILL STICK OR HANG AND THEN RELEASE ABRUPTLY CAUSING THE VEHICLE TO MOVE SLIGHTLY BACK AND FORTH IN THE LANE. AT TIMES IT IS BAD ENOUGH TO RESEMBLE A VERY DRUNK DRIVER OVER CORRECTING. IT IS BAD ENOUGH THAT WE DON'T FEEL SAFE DRIVING THE VEHICLE AND IT ONLY HAS 30,000 MILES ON IT. IT'S A SHAME FIAT/CHRYSLER WON'T ACKNOWLEDGE THERE IS A PROBLEM. WE HAVE HAD A FEW CLOSE CALLS BUT NO ACCIDENT YET DUE TO THIS PROBLEM. ALSO THE PROBLEM WILL OCCUR ANYWHERE AT ANY SPEED EXCEPT TURNING. IT SEEMS TO HAPPEN MOSTLY WHEN GOING STRAIGHT. WHEN IN A TURN AS LONG AS THE STEERING WHEEL IS IN MOTION IT DOESN'T HANG BUT IF IT STOPS AND YOU START TO TURN…”
