What 2018 Fiat 500X owners say
Engine & cooling
I purchased my vehicle in 2020. I was not aware there was an open recall on this vehicle for an oil consumption issue. The dealer did not tell me and I received no notice from Fiat/Chrysler over the next two years. I began having a problem with the engine cutting out as I was driving down the road without any warning. There were no low oil or engine lights coming on to let me know there was a problem. My car was literally stopping on the road as I was driving! The potential for disaster was high! Fortunately we were able to get the car to the dealer without incident. We actually found out about the recall through our own investigation. The car was 3.5 quarts low and has since had two oil consumption tests that were supposed to "fix" the problem. It is now July 2023 and am still dealing with the car burning oil at a rate of about 1.5 quarts every 1500 miles. …
I purchased my 2018 Fiat 500X POP used in April 2023 with only 22k miles. This past weekend 12/16 when I would first start my car up and get ready to leave in the mornings after having been parked for the night, my car would start up normal and I could proceed down the street. The minute I apply the break my car would lose power, stall out or shut off completely. I would press the start button, release the break, shift the gear to drive and proceed forward. I would go about 20 mph as I was driving in a residential area then my car would stall out and shut off again leaving stuck in the roadway. I repeated the start process to pull over to a safe location. I called the dealer and they said there are no recalls for this issue, however, I located one, but my VIN is not coming back as one of the affected vehicles. …
Electrical system
THE Transmission Valve Body Solenoid was diagnosed as not working. while i was driving on the highway without any indication the car just started slowing down . There was not a warning or anything, then the transmission service lights up, i had to have my car towed to a dealership however they informed me that there was never any service they were supposed to do on my transmission because of the type of vehicle i have. this part is expensive and not easily obtainable. car is still showing transmission issue.
Car continuously throttled while driving on highway and road with no warnings. Vehicle electric components like radio and parking camera would shut off and not come back on without warning or while using camera. Car now gives warnings of vehicle temperature too high

There is an active recall for the power train control module for this car but it is not showing up in the NHTSA list. https://static.nhtsa.gov/odi/rcl/2018/RCRIT-18V524-1313.pdf identifies the specific recall for the powertrain control module for the Fiat 500X https://www.nhtsa.gov/vehicle/2018/FIAT/500X/SUV/2WD#recalls lists the recalls done for the vehicle and it does not list the powertrain control module recall issue. We just bought this car from CARMAX and looks like this campaign recall fix was not listed on the site so they didn't address it and now the car wont work or run. If the recall was listed by the VIN they would have been required to fix before selling.
