Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

I received a customer satisfaction notification from FCA US LLC stating they were recommending some improvements on my 2017 Fiat 500X equipped with a 2.4L engine. They had determined that some vehicles may have been consuming more oil than usual. We had noticed our car running low on oil between oil changes so we took it to our local Fiat dealer with the letter and they stated it wasn't coming up in their system so they couldn't run the test for us. We contacted Fiat directly and they stated the same thing. We did receive a letter so I don't understand what the issue is. My daughter drives the car and now I feel it's a safety issue for her. I wrote a letter to the FCA and have not yet received a response. I need help with this issue and running out of resources to help.

What component or system failed or malfunctioned, and is it available for inspection upon request? - The component that failed is the RFHM module in the rear driver side wheel well of the car. Due to water leaking into the car, the RFHM module is taking on water damage causing several electrical systems to fail including power steering, airbags, and starter. Both current RFHM and previously damaged RFHM module are available I believe. How was your safety or the safety of others put at risk? - As the car takes on water, the module fills internally with water as well. When this happens, several components of the car begin to go haywire including security, power steering, airbags, and other electronic readers. When this happens going down the road, my car has and can potentially shut itself off which is very dangerous going down a highway. Has the problem been reproduced or confirmed by a dealer or independent service center? - I first diagnosed what was going on through with my car through other online forums of people experiencing the same problems. I took my vehicle to my mechanic where he ordered a new RFHM Module and had a mobile locksmith acquire a new key. The locksmith was able to program one old key and one new key with the new module and the car was good to go again. Now, six months later, the same issue is happening with the same piece of equipment. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - I have not pursued this yet but will be in touch with the manufacturer tomorrow. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - There is no way to know when the car will work or when it won't after it rains or after a car wash. The symptoms come on suddenly and take time to dry out to be useable again.

ON JANUARY 9TH, 2018 I LEASED A NEW 2017 FIAT 500X FROM FIAT AUTO GALLERY VAN NUYS AT 5711 VAN NUYS BLVD, VAN NUYS, CA 91401. TWO WEEKS LATER WHILE WASHING MY CAR FOR THE FIRST TIME, I NOTICED SOME CLOUDY SPOTS ON THE CAR'S EXTERIOR PAINT (3 SPOTS) AND WHAT APPEARED TO BE A BURN SPOT ON THE LEFT PASSENGER DOOR. I IMMEDIATELY TOOK THE CAR TO THE DEALERSHIP FOR INSPECTION. THE DEALER INFORMED ME THAT IT WAS A MANUFACTURING ISSUE THAT NEEDED TO BE HANDLED BY FIAT. THEY TOOK PICTURES AND WERE SUPPOSED TO CONTACT THE APPROPRIATE DEPARTMENT AT FIAT TO HANDLE MY CASE. AFTER SEVERAL WEEKS OF NO ACTIVITY, I CALLED CUSTOMER SERVICE AT FIAT DIRECTLY AND HAD THEM OPEN A CASE FOR ME. THE CASE AGENT COORDINATED WITH THE DEALERSHIP TO SEND THE PICTURES TO THE APPROPRIATE DEPARTMENT AT FIAT, AN INSPECTOR CAME OUT TO INSPECT MY VEHICLE AND IT WAS DETERMINED THAT IN FACT, MY CAR'S PAINT HAD A MANUFACTURER'S DEFECT. THIS WAS DETERMINED BACK IN APRIL AND FIAT HAS FAILED TO RESOLVE MY CASE. I HAVE CALLED SEVERAL TIMES AND HAVE BEEN LIED TO REPEATEDLY THAT SOMEONE WOULD BE IN TOUCH WITH ME TO EITHER REPLACE MY VEHICLE OR HAVE ME TURN IN THE VEHICLE FOR A FULL REFUND. IT HAS BEEN 10 MONTHS SINCE I ALERTED FIAT OF THE ISSUE AND THEY REFUSE TO RESOLVE MY CASE.
