The Fiat 500X has a defective part, which is the Fiat Ambient Air Temperature Sensor. The dealer here claims that they replace this part at least once a month, and there are barely any Fiats on the road here. I called their customer satisfaction center and they said they are "sorry for the inconvenience" and cannot provide any assistance in the matter. The inconvenience, specifically, is: that this part is a known problem, that the entire mirror needs replaced and the door will need be disassembled to complete that work, that the mirror isn't provided in the color of the car so there is also painting involved, and the total cost is around $2,000. The part itself is just a little $10 bit, but because of the ridiculousness involved in this faulty part, the cost is bombastically high. So, that leaves me waiting for a part that is in short supply because they need replaced constantly, and having to drive in extreme heat until it's fixed. No one should have to pay thousands of dollars or die of heat stroke because of a faulty, tiny, $10 sensor.

The drivers door is defective and will not open from the outside. Upon request the inspection has a cost of upwards of $1000 and customers who drive Fiat 500x models across the US have reported this as an issue. This becomes a safety problem as if there were to be a major accident, I would not be able to be rescued through the door unless I open it through the inside. This is particularly a problem if I were to have a medical emergency. There were no warnings that appeared until this door suddenly would just not open. Additionally, this is a commonly reported issue, as was confirmed to me in person at the dealership, through online forums, and through a customer support chat attached below.

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.

I lease a 2016 fiat 500x in may of 2020. I received a letter saying there was a recall on my vehicle. Recently my car has completely stopped working. It was using up oil to fast. My car would stall out in the middle of the road. Or my car would not turn on completely. I kept up with maintenance ( oil changes etc. ) in June of 2022 my car started over heating. The day before I had just got my oil changed. I took it to the dealership. Which they told me I blew my head gasket. I don-??t believe that-??s is what happened. I believe something else had went wrong. Now they won-??t help me fix my car even when having FULL coverage warranty. and I-??ve been without a car since then.

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 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.

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.

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.

2016 Fiat 500X easy sport AWD. I took my car in last year due to a code it was threw relating to engine cooling fan & found it was on an updated recall; car was stalling both while driving & while at a complete stop, had excessive oil consumption (1 qrt needed every 2 wks), shifted hard from 1st to 2nd and also had odd idling sound at speeds btwn 15-25mph with sudden 'power burst' and last, excessive heat from engine right before it threw the code. Fiat recall assistance very helpful and got me the replacement part and serviced at local dealership. Recall never showed up under NHTSA even to this day. The replacement part seemed to cure all except for the odd idling sound. It's as though car is going to stall any second, almost a 'knocking' in engine and slight shaking can be felt. Recvd notice today from same dealership that took care of last recall on my car. Apparently it has been added to the powertrain recall 16V529000, so I will be scheduling an appt tomorrow. When I tried to find the recall, my VIN search came back with 'you have 0 unrepaired recalls'"?? I had to complete a search without the VIN to find out what campaign it was under. If dealer is sending me alerts, certainly NHTSA should have my car listed for the same recall as they do...you guys do all go off the same recall database as mfg do, don't you"

Car will randomly turn itself off while driving. This has happened 3 times (I currently have just over 70K miles on the car). There are also electrical issues (seizure warning should come with this car- the touch screen radio will turn itself off and on continuously while driving). As with most other complaints, my drivers side door handle came off as well.

While driving my Fiat 500X, it jerks when it's shifting gears or accelerating. I took it into the dealership and there was a bulletin concerning the transmission I believe. But whatever update was done, it did not take care of the problem. I've looked for info regarding this issue and have found there are several other people having the same problem.

The other day my check engine light came on and said that my coolant level was low. I went a grabbed coolant and filled it up to the max line. For two days in a row now, I have been having lights randomly pop up on my dash. Such as drive mode unavailable, service engine, 4WD unavailable. It has also randomly stalled while driving with my son in the car. The dealership said there is nothing wrong with the car. Which there obviously is. I searched and numerous people have had the same issues with their 2016 Fiat 500X, and the dealerships all say the same thing. Incidents have allhapened while the car was in motion. On neighborhood roads to interstate. At speed mileage of anywhere from 15-70mph.

This vehicle has 3 recalls and I didn't see them all listed on your website. The new recall I will enclose in a document. The first recall was an issue with shifting into all wheel drive and connected to the electrical system. The cooling agent fan is malfunctioning which can overheat and cause risk of injury and possible fire in engine. I started noticing my check engine light would go on after start up even though I wasn't due for one. I checked oil and it was fine. My car started jolting forward and backwards when started.it would jolt backwards while in reverse. It's lost power after starting while reversing in my garge. At times I was afraid it would stall while driving on back roads and while slowing down for turns.on highway and main roads I started smelling heat from from engine and could feel the engine struggling to function. It's at dealership now for recall. Thanks
