2014 Fiat 500L electrical problems

Will not pass emissions due to sensors not going into "ready" state. We have taken it to 4 different mechanics and we were told that the abs module is not communicating. So we replaced it and still nothing. Now we are told that the PCM is not storing memory. There have been no lights illuminated on the dash this whole time, and no codes to determine the underlying electrical issue. With issues like these the car can stall, get stuck in gear, no Abs could cause a crash and not to mention once again will not pass emissions testing due to these issues. The issues have been confirmed by a mechanic at an independent service center. Again, no warming lights or codes, or pending codes for the issues listed above.

I was driving my car down a busy road when I approached a red light and slowed to a stop. I kept my foot on the brake and the car in drive until the light turned green. Then, I tried to use the gas pedal without success and got an error message about needing to switch the gear to neutral. I was stuck in the road, unable to make the drive or neutral options work with the gas. Then, I tried switching my car into park and turning it off and back on again. It flashed on the "P" several times before I turned it off and refused to switch to the driving gear when I turned it back on. I had to put it in neutral and have strangers help push my vehicle off the road into a parking lot. The incident occurred on a busy street in the middle of a holiday weekend afternoon and caused tons of traffic and inconvenience and honking and stress.

Engine randomly stalls and will not restart upon entering on-ramps. Automatic transmission randomly fails and slips into limp mode while accelerating from stop lights or accelerating into highway traffic. This issue has caused numerous light rear end collisions with other vehicles following too closely when the transmission malfunctions, causing the other vehicle to impact the rear bumper of the 500L. I had to have the vehicle towed out of traffic because it would not restart or move under it’s own power

My car refuses to shift gears despite being able to start. The car and its gear shift (and transmission, power train, and any other potentially affected parts) are available for inspection upon request; however, the vehicle would have to be towed as it cannot be driven. There was zero prior warning, notice, etc. Cold weather may be a contributing factor, but this issue has been reported numerous time across this vehicle's make, model, and year (2014 FIAT 500L) by other owners to the federal safety agency already. I've driven it sparingly since I moved states, so there is zero reason for the vehicle to stop shifting gears all of a sudden. Again, the car issued no warning lamps nor other messages nor symptoms of the problem prior to the failure, the failure simply occurred without warning. The vehicle is stuck in my driveway and blocking other cars. Had I been driving when this event occurred, there could have been a serious danger and/or disaster that could have put my life (and others) at risk.

The contact owns a 2014 Fiat 500L. The contact stated while her daughter was driving 50 MPH, the vehicle inadvertently lost motive power. The driver was able to coast to the shoulder of the roadway, and the contact became aware that the vehicle had shifted into neutral independently and was unable to shift back into gear. The transmission warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the body control module. The vehicle was repaired, but the failure reoccurred. The manufacturer was not notified of the failure. The failure mileage was 69,000.

Issues with shifting out of park. Random acceleration, stalling, lagging, & jerking while on the road & in full speed traffic. When took car to dealership was told issues with my PCM. PCM had been recalled & fixed with previous owner in 2017. Now the second time having a PCM issue, couldn't do anything with the already fixed recall so i was forced to pay almost 2,000. Now still leaving me with the same issues. Cruise control accelerates on its own, almost causing accident with other cars on highway. Will be going 60 in traffic & it will randomly start to decrease in speed while foot is fully on gas. Possible throttle body issue, RMPS rev up to red while only going 35mph.

So the dealer fixed the transmission / power train recall in 2020, my car is now doing exactly what the recall states, getting stuck in park, asking me to put engine in neutral and then drive without the car moving, so on and so forth. Fiat, as well as the repair dealer northside imports, is refusing to fix this issue as they state the car is out of warranty, and they feel they fixed the recall. This car only has 73k miles on it. The other issue of complaint is that the wire melted on the blower fan for the ac unit. Smelled burning wires in the car, and both fiat and dealer state that is normal wear and tear. That is not, as it could have caused a fire inside the car, luckily i was able to pull over and put out the smoldering wire. I need this fixed, and fiat is refusing to cover. They stated i need a new power train module and transmission which cost 12k which is 4k higher than the actual value of the car. During this whole time, fiat and the dealership was recommending that i purchase a new car. I want to know how i can get this fixed or the manufacturer to acknowledge they have a safety issue. I also got charged 326 dollars just for them to diagnose the issue. nothing fixed. 326 dollars to plug in a machine for 15 minutes. This is very wrong.
