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 have a 2018 Fiat 500X with less than 40,000 miles on the engine. Currently my dealership and I are trying to get Fiat/Chrysler to replace my engine . They have agreed that under the extended warranty afforded to me through the class action lawsuit filed against them over this that I am eligible for this to repair damage done. Unfortunately we are having issues getting authorization for an engine to be ordered..a lot of bureaucracy! The whole process has been infuriating..and I do think that my safety as a driver has been compromised. Thank you.

The Fiat 2014 automatic transmission on my 500L randomly does not continue to move the car when the transmission is in gear. This is a potential collision hazard to me or other vehicles. The car randomly does not move/accelerate when the gas pedal is depressed. The car coasts to a stop while still in gear and I am pressing the accelerator. I need to restart the car when this happens. From Fiat 500USA: "Cause of this issue is the GSM, manufactured Ficosa International, S.A. of Spain. Wide build tolerances within the Supervisor Microcontroller (SMC) inside the GSM can allow temperature to affect the data transfer rates. When the data transfer rate of the SMC becomes desynchronized with the Main Microcontroller (MMC), the GSM resets and the signals to the transmission may be delayed. This can result in an inability to get the vehicle out of park and/or the transmission not receiving, or there is a delay to receive, the intended gear selection."

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.

While driving down the highway, I noticed my engine began to shake violently and began to make a strong knocking noise. The check engine light then illuminated and started blinking, indicating a serious problem. I immediately attempted to pull over because the car was no longer safe to drive. I waited a few hours on the side of the road and had the car towed to a mechanic shop. They told me that there was an engine misfire on cylinder 3. They then pointed me toward the dealership. At the dealership, they found that three cylinders had exhaust valves that were burnt out, and needed to be replaced. What component or system failed or malfunctioned, and is it available for inspection upon request? - The exhaust valves of cylinders 1, 2, and 3. I have photos of what the valves looked like, but may not be able to retrieve the defective valves. I can retrieve an invoice as soon as I receive it. How was your safety or the safety of others put at risk? - Immediately once the issue started, it was no longer safe to continue driving on the highway. If I had continued to drive, it could have started a fire, or the engine could have stopped working, meaning that I would be stranded in the middle of the highway. Has the problem been reproduced or confirmed by a dealer or independent service center? - Yes. The dealership has determined the exhaust valves were at fault. The same dealership also had another vehicle with the same issue in the shop at the same time mine was in the shop. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - Yes, the dealership has inspected the part. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - There were no prior warning signs to this issue besides a slightly higher idle than usual. Immediately when the issue happened, the check engine light illuminated and started blinking.
