2016 Fiat 500X started but would not turn off. I’ve had to get it towed out of work, my batter has died from it being on all night and a day as well. Ive had to get my coworkers to help me out and take my home after it died. The only signal I got prior was a keyless entry. I changed the batter on my key and nothing worked! I would not drive my car far in fear that it would do this far from my job or home! Dealer says that the RF Module is bad due to water leaking into the car. Dealer says that the RF module and another module needs replaced and possibly the two key FOBS will have to be replaced if the current keys do not sync up with the new RF module. I even had my battery replaced that day I went to the dealer. Thought that would help and it did for a bit.

April 2023 - While driving at ~ 35mph multiple warning light on the dashboard came on, (including traction control, AWD needs service, drive mode unavailable, emergency brake and several others) the speedometer stopped working (both the digital and analog) and a sluggish sensation was immediate (like the brakes were applied rapidly.) The car was stopped and further investigation showed that the rear brake lights were on, seemingly indicating that the brakes were engaged while the car was in park, with no one in the vehicle. The car would not shut off. The car was taken to the dealership where over 30 codes were reported. 2 sensors were replaced (one brake sensor and the traction sensor) and the dealership reported that multiple updates were performed in the 2 weeks that they had the car. Five weeks after getting the car back from the dealership the SAME condition occurred on the highway at 55mph, in a construction zone with no ability to pull off. After reaching an area where it was safe to pull off, a restart of the car (by disconnecting the battery) had all of the lights going off and the brakes functioning normally. The car was driven straight to the dealership where the issues happened again. The car now has 43 codes. They replaced the HCU/ABS module, which did not fix the issue. The car has been in the service department for 3 weeks without discovering the cause of the lights, lack of speedometer and deceleration.

My low pressure oil light continues to pop on and off. My pressure is reading very low numbers and not the required number needed for the oil to reach the top of the pump. The dealership replaced the censor on the car and it continues to pop up. This issue has been confirmed by the dealership advisor that it can be internal with my motor and continues to say it is not covered under the motor recall that was previously done in 2021 on my car. I have spoken with Mopar representative and they have stated that I have a 2 year warranty and that my current issue falls under the guidelines for motor recall. The component has not been inspected by the manufacturer. My oil has been changed and it is full. This is a safety concern because if I am driving my car and something happens to the motor or if the motor locks up while driving, I will severely be injured after i have explained to the dealership my concerns.

The radio frequency hub has failed or shorted out from possibly water leaking into vehicle. This has caused the car to randomly stop while driving and other times to not start. The car completely stops locking the cars braking system and not allowing the doors to open. The car that has stopped working while Driving and has been stuck locations unable to start. Diagnostics said the car was fine until it has completely shorted out which has made the car unusable and no diagnostics can be run. When the car was brought into the last dealership they were familiar with this problem due to several other vehicles with the same problem being brought in. The mechanics states that this is a problem from water leaking into a part on the trunk hatch that is supposed to be sealed. There have been several cars repaired at the dealer and currently other cars currently waiting for a back ordered part to try to remedy this problem.

1 year after purchase the car started having electrical issues, hard gear shifting, turns off or fails to start on first try, car has been serviced at South Miami FIAT since the issues started. The dealer could not identify the issues and told me that they would leave a warranty order open in the event that the warranty expired and the issue was not addressed. The dealer is basically not assisting. I have recently taken my car in for the oil consumption test; at first it failed to later be told that it's working just fine. Problems do no fix themselves and I feel that the dealer is not being totally honest with the situation. I am aware that the consumer is on the losing end of this story, but I will say that I along with many others have had a less than desirable experience with FIAT vehicles. Can someone please respond regarding these issues. I know that the past 2 years have been strenuous on all, but this is my last effort to find a solution to this matter. I have reviewed many other owners with almost identical issues with their cars. Thank you for your attention
