2014 Fiat 500L Powertrain (other) 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.

after looking at all of the complaints within NHTSA there are approximately 50 pages of combined complaints with each page showing 4 "call outs" and the majority being Power Train and reading pretty much all of them it appears that they are all the same issue. Their vehicles along with mine were not recalled; but we are having the same issues. What is needed or what needs to happen for all of the 500L Fiat being recalled for the Power Train issue? Does somebody need to die due to the failure of the Power Train when they are in traffic and the vehicle basically shuts down and/or off? Note, the miles on these complains vary from 55,000 up to 100,000

CAR CONTINUES TO HAVE SHIFTING GEAR ISSUE. WENT TO A MECHANIC WHO DID A DIAGNOSTIC TEST ON IT AND THE RESULTS ARE: Transmission Error Messages U0415 and P1CB1 and OBDII Codes ($03) shows the same error message as Transmission P1CB1 Manufacturer Specific. the closest Chrysler Dealership is unable to perform anything on this vehicle as they no longer are licensed for the Fiat Software. Hence, they are unable to inform me if this is covered by Fiat or if this is something that I need to fix out of pocket. Seeing that the 214 Fiat 500L does have a Power Train-Automatic Transmission Control Module and Power Train: Automatic Transmission (moving the transmission shift lever may have a delayed effect or no effect on selecting a transmission gear) = I believe it is covered, but it is not showing as a recall for my VIN #. How do I submit this or where/who can assist is getting this recalled and corrected?

The contact owns a 2014 Fiat 500L. The contact stated that on several occasions while the vehicle was running, the transmission warning light illuminated, and a "Possible Ice" message was displayed even though there was no inclement weather. The vehicle was taken to a dealer; however, the failure was not replicated. On another occasion while stopped, the accelerator pedal was depressed, and the vehicle failed to accelerate. The message "Shift into Neutral and Then Select Gear" was displayed. The contact shifted from Neutral to Drive. The vehicle was turned off and restarted. The vehicle was then towed to the same dealer, where it was diagnosed, and determined that the lifters needed to be replaced. The vehicle was repaired, but the failure reoccurred within a month. The vehicle was taken back to the dealer, where the dealer stated that the vehicle was already repaired. The vehicle was then taken to an independent mechanic, but no diagnostic result was provided.

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.

When pressing on accelerator, it would not accelerate properly. Therefore having to press accelerator more while not going at accurate speed. Furthermore as driving the vehicle one day fully pressing on accelerator vehicle would not accelerate. Therefore, having to stop in the middle of the road going uphill.

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 NHTSA 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.

When in traffic on the highway the car all of a sudden would not shift out of first. Following that, all power was lost to the drivetrain, but accessories were still powered and working. Before the car gave no power to the drive, the oil light came on in addition to the engine light, when the oil levels were checked they were confirmed to be normal. The car has been inspected by a mechanic who suggests replacing the entire transmission.

CAR INTERMITTENTLY SHIFTS OUT OF GEAR INTO NEUTRAL WHEN faced with an uphill grade forcing car backwards. We have had over 5 nrear accidents involving rolling off hillsides ar onto property or into traffic behind. Car will not engage we have been desperately against a steep hill many times. Also front ABS brakes intermittently grab 1 wheel forcing car sideways at 40 mph. Also car emits rattle sound coming from lower gearbox or engine area noticeable through cab, both before and after a complete $4300 transmission rebuild. Service completed by FIAT and Alfa Romeo od Van Nuys California. This car is going to kill us. Fiat is dragging their feet. I will list the first incident below at March 18, 2023 but then many more occurred after, even after trans rebuild. This design is life-threatening. Who rebuilds a trans at under 50,000 miles??

My car is experiencing the same issue as a previous recall T19. Does not go when foot is pressed completely on gas . Will start & only go 25mph & sound like it is stuck & will not shift. Then randomly will jerk & accelerate. Tool to local mechanic Oct 2023. went for oil change, just befor appointment started running weird and check engine light had came on,asked him to check it out. Local mechanic said reader said knock sensor. paid for part,and went for pick up. Check engine light was off, ran good for about 5 mins on way home had to turn around. Took it back now local mechanic says theres mice damage to wiring harness. estimated 3,000-5,000 total. after already paying 800 for knock sensor and oil change. Told to try & see if insurance will cover rodent damages . Insurance has towed car to Fiat dealership, now being told there is zero mice damage to my wiring harness. Replaced knock sensor now for a second time, still not the fix. Was told the Issue is unrelated to the mice & has to do with my PCM. Repair cost is more than my car is even worth at this point. Sounds just like past PCM recall issue. Mine was apparently fixed 03/23/17. Is there a way there could be another recall? I have under 70,000 miles & do not understand how this has happened.

I had to play with the shifter to get it out of reverse it wanted to stay in reverse. And I was afraid it was going to run someone over because I. Couldn't park it
