Compramos un fiat 500 x en el 2016 nuevo y hemos sido los unicos propietarios de ese auto o sea que se ha cuidado con esmero conduciendolo muy cuidadosamente y resulta que a las 35000 millas que es lo que ha caminado hemos tenido que cambiar los soportes del motor que normalmente se hace a las 80 o 90000 millas. Hemos tenido que pagar 1386.00 dolares en el dealer para su reparacionporque la garantia no cubre esas piezas( los 3 soportes del motor) y es logico pensar que esto sea un defecto de fabrica al poner piezas de poca calidad.Queremos que alguien nos de una explicacion y nos devuelva la fabrica el dinero invertido.Ya el auto fue reparado en el dealer.Gracias por su atencion.

For 2-3 days prior to incident, upon shifting up a gear and disengaging clutch, RPMs were higher than expected (noticeable revving sound when hitting gas pedal). Wednesday 12/08/21, the vehicle was not maintaining speed on the highway and engine was revving like it was in too low a gear. Vehicle stopped accelerating and lost speed while driving on highway forcing me to pull over and forcing a tractor trailer to swerve around me. Vehicle was disabled at that time. No warning lights were displayed on dashboard. Frederick Auto Repair in Frederick, MD says clutch needs to be replaced despite the vehicle only having ~53,300 miles. Initially thought it would be part of Safety Recall S34/16V-302 but this appears to be for a different model and my vehicle's VIN is not included.

Since the car was purchased, the electrical system seems to have an issue that no dealership has been able to diagnose or fix. The forward collision warning system will intermittently turn itself off upon starting or even while driving. The car also frequently blows passenger side lights. More recently at about 67,000 miles, the check engine and transmission warning lights came on while highway driving 2.5 hrs away from home. The car has been in and out of the shop at least 3 times over the past month and a half to try and fix the issue but they have been unable to determine what is wrong with it. They said they found metal in the transmission and therefore replaced the torque converter and valve body. However, the issue persists. A burning smell can now be detected when driving. Car is going into the shop for a 3rd time to try and fix it - leaving owner without a vehicle for another undetermined amount of time and many miles away from home (this time >500 miles away from home). The car supposedly passed all previous recalls - cooling fan, oil consumption, etc. All regular service/maintenance intervals have been kept by the owner.

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

Currently the car won’t shift gears out of park. I had it towed to dealer to have it diagnosed and then to another mechanic for a second opinion. There were no warning lights and transmission fluid is not low. It has been a year since it happened (October 2020) and it’s parked because replacing transmission is 6k according to dealer. Manufacturer has not recalled my specific vin but the dealer has told me there are thousands of cars of this model recalled for same exact issue already. This car also the year prior turned off and stayed in park twice. Once at a stop light and then once in park but both of those two times it resolved itself. I took it to the dealer but they couldn’t find anything at the time because it has gone back to working. This is in Georgia. Additionally, the lights go out approximately every 6 months. It’s not fuse or bulbs so I’m forever changing lights. This of course not being the bigger issue. The dealer can’t find what’s causing this but we know for sure the transmission issue is one that’s been recalled in other VINS of this year, make, and model.
Chrysler (FCA US LLC) is recalling certain model year 2014-2015 Jeep Cherokee and 2015 Chrysler 200, Jeep Renegade, RAM ProMaster, and 2016 Fiat 500X vehicles equipped with 9-speed automatic transmissions. The transmission sensor clusters may have insufficient crimps in the transmission wire harness, and as a result, the transmission may unexpectedly shift to neutral. On August 29, 2016 Chrysler added the 2016 Fiat 500X vehicles to this recall.
Consequence & remedy
Consequence: If the vehicle unexpectedly shifts to neutral, there is an increased risk of a crash.
Remedy: Chrysler will notify owners, dealers will reprogram the Powertrain Control Module and the Transmission Control Module and if necessary replace the transaxle range sensor wire harness, free of charge. The recall began on November 7, 2016. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is S55.
