The contact owns a 2016 Fiat 500X. The contact stated that while driving at an undisclosed speed, the transmission unintendedly shifted from drive(D) to neutral(N). The RPM became elevated; however, the vehicle failed to accelerate as intended. While driving approximately 15 - 20 MPH, the vehicle went into LIMP Mode. While in LIMP Mode, the contact coasted to the side of the road and waited for several minutes before continuing to drive. The failure had occurred twice. Additionally, the check engine warning light illuminated intermittently. The vehicle had been taken to a certified mechanic, who determined that the transmission had failed and needed to be rebuilt. The dealer also diagnosed that there was a failure with the instrument cluster. The instrument cluster lights were cleared; however, the transmission was not repaired. The check engine warning light remained illuminated. The contact was made aware of NHTSA Campaign Number: 16V529000 (Power Train), for the transmission for the same year, make, and model. The manufacturer was made aware of the failure and confirmed that the VIN was not included in the recall and opened a case. The failure mileage was approximately 144,000.

I was driving vehicle and it all of a sudden get stuck in gear in either park gear or some other gear that wont allow me to turn engine off. Sometimes it just slow down to a stop and will not go into gear again for a while or appears the gears are not engaging putting me at risk for accident on highway. Once it slowed down in traffic and I nearly got hit trying to drive it off the highway. The gears were not engaging putting me at risk of many vehicles hitting me. I was praying someone noticed I had car trouble to slow down as I was no longer in full control of vehicle. After some

Radio unit failed due to internal short which prevents the blind spot alert, parking sensors and backup camera to no longer function. Fiat no longer manufacturers the replacement part (P/N: 6RV00LXHAA) and states vehicle is not repairable. Car is less than 10 years old and has 25k miles but can no longer be safely operated due to the failed safety systems. Other than this issue car is essentially like new and could provide another decade of use but instead must be added to the overflowing landfills creating yet more pollution. Vehicle manufacturers should be held accountable for such egregious behavior.

NHTSA ID 11627486 · filed Nov 26, 2024

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 day after we had a bad storm, my car's electrical system went haywire. I was driving to work and all kinds of warning lights started flashing. Then when I came to a stop sign, stopped, then proceed to go again the car car would not go. I was still in drive but the car would not go when I pressed the pedal. So I put the car in park then back in drive and it started driving again. Then a warning came on about my power steering. I get further down the road to a stop light. I stopped and when the light turned green it would not go again while it drive. So I put it in park and back in drive and it went.i get to a stop sign about 1 mile down the road and my steering wheel locked up. So I put the car in park and back in drive and it started turning a little bit so I was able to pull off the road into an abandoned parking lot. I tried to turn the car off and it would not turn off. So I unhooked the battery cable and it cut off. I had the car towed to my house. They hooked the cables back up yo get the car onto the tow truck. Once the car was home, the wheel was fine but it had some warning messages on the dashboard. So the next day it rained again. And I went outside later that evening and my tail lights and the dashboard was illuminated. My air conditioner was running but the car was not crank. So I finally got it to the shop and they are saying water got into the RHA hub; but how? I don't have a leak in my car. I've never seen water in my car and on top of that, why is my RHA hub in the trunk? Anyway, after that I looked it up and come to find out a lot of people with Fiats have been having the same problem. And they are just as upset and lost as I am.

THIS CAR IS A LEMON AND THE DEALERSHIP IS FULLY AWARE. SINCE THE BEGINNING, THE CAR WILL RANDOMLY SAY DRIVE MODE UNAVAILABLE, EVEN WHILE IN OPERATION. IT GOES INTO NEUTRAL WITHOUT SHIFTING AND ALWAYS HAS. THE TRANSMISSION MESSES UP IF I SWITCH INTO SPORT FROM AUTO ON THE HIGHWAY AND IT ALWAYS HAS. THE STEERING WHEEL FELL APART ON MY WAY HOME FROM WORK AND I HAD TO CALL THE DEALERSHIP, IT HAS STARTED FALLING APART AGAIN. THE DASHBOARD STARTED COMING APART AND THAT HAD TO BE REPAIRED. THE TRUNK LOCKS WHEN IT FEELS LIKE IT, AND ALWAYS HAS. I WILL CLOSE IT AND IT WILL IMMEDIATELY UNLOCK. THIS PREVENTS ME FROM LOCKING THE CAR AND I DON'T KNOW IF IT'LL FLY OPEN IF I TRY TO DRIVE IT. I HAVE TO WAIT FOR IT TO LOCK. THIS CAN LITERALLY TAKE HOURS! 2 WEEKS AGO, MY CAR ACTUALLY STARTED BY ITSELF AT 10:30 PM. I HEARD A CAR ALARM AND ASSUMED IT WAS A NEIGHBOR'S CAR. IT WAS MINE. MY KEYS WERE DOWNSTAIRS IN MY PURSE. I WAS UPSTAIRS BINGING LAW AND ORDER SVU. I COULDN'T GET THE CAR TO SHUT OFF. IT WAS RAINING AND DARK AND I LIVE ALONE AND I DON'T KNOW MY NEIGHBORS. LUCKILY SOMEONE CAME TO HELP ME ANYWAY. THE ALARM AND RADIO WE'RE BOTH BLARING NONSTOP. THE FUSE FOR THE FUEL HAD TO BE PULLED, TO SHUT IT OFF. THIS HAPPENED FOR TWO DAYS IN A ROW. NOW IT WON'T START. THE BATTERY IS FINE, THE RADIO AND LIGHTS AND DASH LIGHTS COME ON. EVERY POSSIBLE MECHANICAL FAILURE CODE IS SHOWING UP, ABS SYSTEM, KEYLESS ENTRY, POWER STEERING, REMOTE START, AIRBAGS, CHECK ENGINE ETC ARE ALL SHOWING AS DEFECTIVE. THIS CAR IS A LEMON. POMOCO JEEP CHRYSLER IN NN, VA, KNOWS IT'S A PIECE OF CRAP. INSTEAD OF LABELING AT WHAT IT IS, THEY EXPECT ME TO BRING IT IN CONSTANTLY AND CONSTANTLY BE WITHOUT TRANSPORTATION. IF I DIDN'T NEED A CAR, I WOULD NOT HAVE PURCHASED ONE. I WOULD LIKE A CERTIFIED MECHANIC, INDEPENDENT OF CHRYSLER AND IT'S DEALERSHIPS, TO FULLY EXAMINE AND DIAGNOSE THE ISSUES WITH MY CAR.

EVERY SINCE I PURCHASED MY 2016 FIAT 500X EASY AWD IN 2017, I'VE HAD ISSUES WITH MY HATCH LATCHING MECHANISM. I'LL BE DRIVING ALONG AND IT WILL OPEN ON IT'S OWN, WHICH IS DISCONCERTING ESP WHEN I HAVE STOWED SOMETHING AND THIS HAPPENS ON A FWY, MAJOR SAFETY CONCERN FOR THOSE DRIVING BEHIND ME! DEALER COULD FIND NOTHING WRONG, THOUGH NUMEROUS COMPLAINTS CONTINUE TO BE LOGGED ABOUT IT. THEN EARLIER THIS YEAR, I WENT TO OPEN THE HATCH AND THE RUBBER PUSH-BUTTON FELL OUT. I WAS ABLE TO GET IT BACK IN THERE BUT THAT ONLY TOOK A PASSENGER SLAMMING THE HATCH SHUT FOR ALL OF THE PARTS TO FALL OUT IN TO THE STREET. NOW IT WILL NOT OPEN FROM THE OUTSIDE NOR THE INSIDE. CALLED DEALER WHO REFUSED TO GIVE ME A BALL-PARK PRICE BUT DID SAY WHEN I DO BRING IT IN, I'LL BE CHARGED A $165 DIAGNOSTIC FEE WHETHER I HAVE IT WORKED ON OR NOT AND THAT FEE DOESN'T EVEN GO TOWARDS THE ACTUAL REPAIR/REPLACEMENT/LABOR COSTS. SERIOUSLY? I HAVE TO PAY THEM $165 JUST TO DIAGNOSE WHAT WE BOTH ALREADY KNOW WHAT IT NEEDS, BUT WOULD TAKE THEM ALL OF 5 MIN TO CONFIRM & THEN TAKES 5 DAYS FOR THE PART TO COME WHICH I'LL BE KEPT IN THE DARK FOR THAT COST UNTIL HE HANDS ME THE BILL? SINCE WHEN DO SERVICE TECHS GET PAID THE FULL HOUR FOR 5 MIN OF LOOKING - NOT DOING ANYTHING AND THEN NOT EVEN APPLY IT TOWARDS THE ACTUAL DOING?! IS THIS LEGAL?! THEY SHOULD NAME THE FEE MORE APPROPRIATELY THEN, THE JUST BECAUSE WE CAN FEE. I'VE BETTER TITLES FOR THIS PRICE GOUGING, BUT WILL REFRAIN SO THAT THIS COMPLAINT MIGHT DRIVE A RECALL FOR THIS FAULTY HATCH LATCH MECHANISIM.
