“I've had 3 different issues with the transmission- There's been 1 recall on the clutch- The transmission put me in Great danger I was driving on the freeway about 60 mph when the car just popped into neutral- I was terrified and I managed to pull to safety to put the manual transmission into gear- I didn't want it to happen again- I had to hold the gear until I got to an exit to get off the freeway- I had the Fiat towed to the dealership and fixed- then 6 months later driving again and it jumps out of gear into Neutral another scare- I put it in the shop and it cost me $4646,00 to replace the transmission, I really would like this serious safety hazzard investigated so no one gets hurt- I was Blessed to be able to think fast to save my life on a busy Highway my safety and others was put at risk because it could have caused a crash- It gives no warning at all- car is available upon request I have all receipts I can send -for some reason I was unable to download to this Site”
“I bought this car about a year ago, ever since I got the car the first issue started within a month it just started to shut off for no reason first at a traffic light, afterward while I was driving called the dealership who sold me the car I was told to bring it to find out they did not have a certified Fiat Mechanic that would be able to look at the car so it was towed to another dealership. I was told they fixed the issue but once again the vehicle started doing the same thing even more frequently fast forward my car has yet to be fixed I feel like I am going to get rear-ended and hurt really bad and all I get from the dealership is that they can't fix it. My question to them is why I sell me a car that you knew you could not repair or you knew you really didn't check properly as per your words you don't have a certified mechanic.”
“THE STARTER MOTOR FAILS TO ENGAGE AT RANDOM TIMES. I HAVE TAKEN IT TO THE DEALERSHIP AND TO LOCAL MECHANICS AND NONE HAVE BEEN ABLE TO REPLICATE THE ISSUE. THE STARTER MOTOR WILL SOMETIMES START RIGHT UP FOR THEM, CAUSING THEM TO RULE OUT A FAULTY STARTER. IF THE VEHICLE IS LEFT OVER NIGHT, IT MAY START RIGHT BACK UP. AFTER SELLING THE CAR ON 2 OCCASIONS, BOTH NEW OWNERS REPORTED WITHIN 24 HOURS OF OWNERSHIP THAT THE VEHICLE WOULD NOT START AFTER HAVING DRIVEN IT FOR MORE THAN 10MI. I BELIEVE FCA IS WELL-AWARE OF THIS RELATIVELY COMMON ISSUE. A GOOGLE SEARCH FOR THIS PROBLEM YIELDS PAGES UPON PAGES OF OWNERS REPORTING SIMILAR ISSUES. I CAN SHARE YOUTUBE VIDEOS OF OWNER'S EITHER REPORTING THE PROBLEM OR COMMENTS OF OTHERS HAVING A SIMILAR ISSUE HTTPS://WWW.YOUTUBE.COM/WATCH?V=L7SOEZKWUT4 HTTPS://WWW.YOUTUBE.COM/WATCH?V=PFFVY3ARSVS”
“WHILE DRIVING HOME VIA LOCAL CITY SURFACE STREETS, THE GEARBOX FAIL LIGHT AND THE HAVE TRANSMISSION CHECKED MESSAGE CAME UP ON THE DASH CLUSTER. I DROVE THE CAR 4 MORE MILES TO A SERVICE STATION, STOPPING TWICE ON THE WAY. THE CAR BEGAN RUNNING POORLY. INCLUDING BUCKING, REVVING HIGH, WHILE STAYING AT LOW SPEED, STALLING AND BUCKING AT LIGHTS LOW IDLE OR STOPS. THE SERVICE STATION SAID OTHER THAN A LOW NUMBER (4 TIMES PER 1000 I THINK...A CYLINDER MISFIRE) NO CODES CAME UP. WHEN RESET THE CAR WOULD RUN BRIEFLY AS NORMAL BUTAT FIRST STOP ALL ISSUES WOULD RESUME IN FULL AGAIN. I WAS ABLE TO DRIVE THE CAR HOME (2 BLOCKS) BUT WAS NOT SURE IT WOULD MAKE IT. IT SITS IN MY PARKING SPOT AS WE SPEAK.”
“WE'VE REPLACED THE SHIFTER CABLE ON THE FIAT TWICE ON OUR OWN. RECENTLY, FIAT REPLACED IT UNDER RECALL NO. 19V817000. FIAT'S REPLACEMENT CABLE/BUSHING LASTED THREE SHIFTS. SHIFTED INTO DRIVE TO LEAVE THE DEALERSHIP. SHIFTED INTO PARK AT HOME. SHIFTED INTO DRIVE ON NEXT USE AND THE CABLE WAS DETACHED. FIAT'S SOLUTION IS NOT AN IMPROVEMENT. COMPARING THE REPLACEMENT BUSHING WITH THE OLD BUSHING, THERE ISN'T ANY DIFFERENCE THAT WILL PREVENT THIS ISSUE. THIS IS A DANGEROUS ISSUE. THE FIRST TIME IT OCCURRED WE WERE STUCK IN THE MIDDLE OF THE STREET FROM REVERSING OUT OF A PARKING SPORT AND THE CABLE BUSHING FAILING WHEN WE WENT TO PUT IT IN DRIVE. THE REPAID UNDER 19V817000 IS NOT A CORRECTIVE REPAIR.”
“CAR SOMETIMES CUTS OFF WHILE DRIVING WITH NO WARNING. ALL GUAGES SPIKE, CAR CUTS OFF. I PULL OVER AND IT STARTS BACK UP. NO CODES WERE STORED. THIS IS VERY DANGEROUS. CAN'T FIND THE PROBLEM.”
