NHTSA Complaint #11698815 — 2016 FIAT 500X

While driving, the vehicle suddenly shut off completely in the middle of the road, forcing me to come to a full stop and make several attempts before it restarted. During the incident, all electrical power was lost—I was unable to use hazard lights or blinkers, and I’m unsure if the brake lights worked when pressing the pedal. This created an extreme safety risk to both myself and other drivers. About a month earlier, the same issue occurred and the dealership diagnosed it as a “battery, fuse, array” problem, replacing the battery. The same issue has now returned, and the dealership has identified it as a MultiAir actuator failure. The vehicle is a Fiat 500X equipped with the 2.4L Tigershark engine, which has known problems with the MultiAir system. The car has only around 60,000 miles and is currently at an authorized Chrysler/Fiat dealership, available for inspection upon request. The problem has been confirmed by the dealer, no warning lights appeared before the failure, and a technical case has been opened with Fiat/Stellantis corporate.
