What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I received a customer satisfaction notification from FCA US LLC stating they were recommending some improvements on my 2017 Fiat 500X equipped with a 2.4L engine. They had determined that some vehicles may have been consuming more oil than usual.
Due to water leaking into the car, the RFHM module is taking on water damage causing several electrical systems to fail including power steering, airbags, and starter. Both current RFHM and previously damaged RFHM module are available I believe. How was your safety or the safety of others put at risk?
February 2023 the Fiat breaks and transmission locked up and all of the lights on the dashboard started flashing in the middle of the road. filed claim with geico.
The contact stated that while driving at various speeds, the vehicle would suddenly stall. After restarting the engine, the vehicle would operate as normal. The vehicle was taken to the local mechanic who discovered no engine oil was present inside the engine.
The forward collision warning system does not function at all. Took it to two different fiat dealers and since there are no codes system operating, but does not work at all.
I do not know if this is what is wrong with my car, but the mechanic did indicate that the oil consumption issue manifests itself in the ways I have
Service transmission light appears followed by "drive mode unavailable." when this happens, the vehicle is basically in "neutral." this happened several times while driving, including city streets and on a 65 mph highway.
The seat belt will not buckle. But shows that it is buckled.
