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."

For the past several months my car will simply stop accelerating while I am driving down the road. I can put my foot on the gas, and it will not accelerate. The RPM's and speed go down and I must pull over to the side of the road quickly and turn the engine off, wait 5 minutes or so and try again. Sometimes I must wait longer before it will go back in gear and accelerate. It has been very unsafe when this happens on the interstate putting me, my passengers, and other cars/drivers at risk because it happens with no warning lights and not enough time to get over. This same problem happened before in 2017, and FIAT issued a recall. The dealership stated that recall was fixed and cannot use it for this problem even though it is the EXACT same issue. They state I need a new transmission now costing $9,876.00 repairs/labor for a 2014 FIAT 500L I bought for $13,000..... If this problem was acknowledged before, why isn't FIAT fixing it again?

Purchased this vehicle from manhattan alfa romeo fiat in dec 2017. It had 17000 miles and I purchased and extended warranty with zurich for power tain from manhattan fiat. The car had 1 recalls for transmission issues on in march 2014 and one in march 2017. The car now needs a complete new transmission and it only has 52457 miles. The repair is over $7000. The warranty is claiming that it will not cover the transmission because it is outside parts of the transmission -hydrallic supply unit but the part can only be replaced as a whole unit. I called chrysler/fiat headquarters and they would not help me. The car has had transmission issues from when it was made. All the recalls and issues with the car they should be able to help me. The extended warranty not covering the transmission repair because they deem it an outside part when it is part of the transmission. Who can a consumer turn to. This is fraud.

This morning I got into the car even tried to put it into drive but it said shift back to neutral then to reverse or forward. I tried just like it said and it still continued throw the error. After like three or four times it skipped first gear and shifted to second gear but the car jerked as soon as I stepped on the pedal. I turned it off for about an hour and then try it again and I had the same problem. This time I put it into reverse and actually went in reverse, then it allowed me to go into first gear. I checked the check engine light code and it threw a p1cb1 code which indicated it was something to do with the transmission. I'm trying to make an appointment with the dealership but for some reason they never answer the phone at the only one near me. But everywhere I'm looking and reading it looks like it's going to have to replace the transmission but cannot verify until I get to the dealership.
