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.

The contact owns a 2016 Fiat 500X. The contact stated upon making a complete stop at a traffic light, the vehicle vibrated. There was no warning light illuminated. The contact was able to continue driving. Additionally, the contact stated while driving 40-45 MPH, the vehicle experienced hard shifting from second to third gear. The contact was able to continue driving. The vehicle was taken to the dealer where it was diagnosed that three motor mounts were fractured and needed to be replaced. Additionally, the dealer diagnosed that the spark plugs, and an unknown seal needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that they could not assist as the VIN was not under recall, and the vehicle was out of warranty. The failure mileage was approximately 79,300.

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.

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

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?

WITH NO WARNING SIGNS I PROCEEDED TO CHANGE BATTERY AFTER WORK AND IT STILL WOULDN'T START THEN AFTER ATTEMPTING TO START WITH NEW BATTERY THE CAR WITH LOCK SYMBOL CAME OUT. STILL AT THIS POINT NO WARNING WAS GIVING AS I WAS DRIVING THIS CAR PERFECTLY FINE UNTIL THIS. ALL THIS WAS ON MAIN STREETS. I HAVE SMALL KIDS AND THIS IS NOT AN ACCIDENT THAT I WOULD EVER WANT WITH OR WITHOUT THEM BECAUSE OF A TECHNICAL ISSUE OF A CAR.

THE CAR RANDOMLY JUMPS INTO NEUTRAL WHILE DRIVING DOWN THE ROAD. I MUST TRY TO COAST TO THE SHOULDER, AS THE DASH IS TELLING ME TO PRESS THE BRAKE PEDAL TO PUT THE CAR IN GEAR. ONCE I'VE STOPPED I HAVE TO MOVE THE GEAR SHIFT TO PARK, SHUT THE CAR OFF AND RESTART IT.
