2013 Fiat 500 Engine Problems

In June 2025, while driving my 2013 Fiat Abarth at highway speed, the vehicle suddenly stalled without warning. This happened on one of the hottest days of the year with another person in the car, creating a serious risk of a high-speed collision. The cause was later confirmed by a different Fiat dealership: a port in the intake/PCV system had been left completely uncapped after service at a Fiat dealership in 2024. The mechanic who worked on my car apparently believed this was only a “vent” and not part of the vacuum system — a dangerous misunderstanding that allowed unmetered air into the engine. This disrupted the air/fuel mixture and led directly to the stall. I have written proof from the dealership admitting to the “vent” claim. A competent technician should know the difference between a vent and a vacuum port. Returning a vehicle in this condition is negligence and puts lives at risk. The component is still available for inspection, and I have documentation supporting my claims.

Dear NHTSA Office of Defects Investigation, I am filing this formal complaint to report the sale and interstate delivery of a dangerously defective and noncompliant vehicle sold to me by Arlington Auto Group, located at 3621 Columbia Pike, Arlington, Virginia. On [XXX], I purchased a 2013 Fiat 500 (VIN: [XXX] ). The vehicle was delivered to my home in Englewood, Colorado on [XXX]. Within 24 hours of taking possession of the car—and having driven fewer than 100 miles—I had the vehicle inspected by a certified mechanic at The Auto Repair Place in Boulder, Colorado. Their findings revealed multiple severe safety hazards, including: Rear brake pads completely worn to metal-on-metal contact Two bolts missing from the rear passenger wheel A destroyed and leaking turbocharger, which increases the risk of engine failure Inoperable tire pressure monitoring system (TPMS) No Virginia safety inspection documentation provided Additionally, the car had been illegally tampered with to bypass emissions systems, including removal of the catalytic converter and installation of sensor bypass wiring, which also violates federal law and emissions standards. This vehicle was represented as safe and legally operable at the time of sale. However, these issues clearly indicate the vehicle poses a substantial risk to public safety and should not have been sold or shipped across state lines. Request for Investigation I respectfully request that NHTSA investigate this matter for violations of federal motor vehicle safety standards (FMVSS) and to determine whether this dealership has a pattern or practice of selling unsafe or defective vehicles. I am prepared to provide: Full mechanic inspection report Purchase contract and shipping records Photos of the damage and mechanical issues Communications with the dealership and lender Thank you for your time and attention to this serious safety matter. Sincerely, [XXX] [XXX] (303) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving down the highway, I noticed my engine began to shake violently and began to make a strong knocking noise. The check engine light then illuminated and started blinking, indicating a serious problem. I immediately attempted to pull over because the car was no longer safe to drive. I waited a few hours on the side of the road and had the car towed to a mechanic shop. They told me that there was an engine misfire on cylinder 3. They then pointed me toward the dealership. At the dealership, they found that three cylinders had exhaust valves that were burnt out, and needed to be replaced. What component or system failed or malfunctioned, and is it available for inspection upon request? - The exhaust valves of cylinders 1, 2, and 3. I have photos of what the valves looked like, but may not be able to retrieve the defective valves. I can retrieve an invoice as soon as I receive it. How was your safety or the safety of others put at risk? - Immediately once the issue started, it was no longer safe to continue driving on the highway. If I had continued to drive, it could have started a fire, or the engine could have stopped working, meaning that I would be stranded in the middle of the highway. Has the problem been reproduced or confirmed by a dealer or independent service center? - Yes. The dealership has determined the exhaust valves were at fault. The same dealership also had another vehicle with the same issue in the shop at the same time mine was in the shop. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - Yes, the dealership has inspected the part. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - There were no prior warning signs to this issue besides a slightly higher idle than usual. Immediately when the issue happened, the check engine light illuminated and started blinking.

HELLO, I BELIEVE I NEED AN ATTORNEY AND LEGAL ADVICE. I HAVE A DEFECTIVE CAR THAT SHOWS ON THE FIAT DEALERSHIP WEBSITE AS A RECALL. THE YEAR MAKE AND MODEL OF MY CAR HAS A RECALL (2/2013 RECALL N09 REPROGRAM POWERTRAIN CONTROL MODULE) I HAVE HAVE BEEN REPORTED MY ISSUE TO FIAT DEALERSHIP FOR THE LAST THREE YEARS AND WAS TOLD THAT BASED ON MY VIN NUMBER I DO NOT HAVE A RECALL. WHEN I SERVICE MY CAR AT DEALERSHIP THEY JUST TURN OFF MY ENGINE LIGHT. I HAVE NOT BEEN ABLE TO PASS INSPECTION OF MY VEHICLE IN OVER TWO YEARS. MY MECHANIC EXPLAINED TO ME THAT I HAVE A RECALL AND HE CANNOT PASS INSPECTION. I AM AFRAID TO DRIVE MY CAR, BUT CANNOT SELL IT OR TRADE IT IN DIE TO THE ENGINE LIGHT ERROR. I HAVE A RECORD OF ALL OF MY RECEIPTS. THIS STARTED IN JANUARY 2018. I BELIEVE THAT I SHOULD FILE CHARGES AGAINST FIAT AND WOULD NEED LEGAL ADVISE. THANK YOU.

ABOUT A MONTH AGO, MY WIFE WAS DRIVING TO/FROM WORK AND NOTICED A "CHECK ENGINE" LIGHT COME ON. WE IMMEDIATELY SCHEDULED AN APPOINTMENT WITH OUR LOCAL STUDIO AND CONTINUED TO DRIVE THE CAR AS NORMAL. AT THIS POINT, NOTHING WAS GOING ON WITH THE CAR, EXCEPT THAT THE LIGHT CAME ON. A DAY OR TWO LATER, THE LIGHT WENT OFF, AND THE CAR CONTINUED TO ACT NORMAL. WE ENDED UP CANCELING THE APPOINTMENT, GUESSING THAT THERE WAS A GLITCH WITH THE COMPUTER. THE VERY NEXT MORNING, MY WIFE STARTED THE CAR TO FIND THE ENGINE SHAKING AND THE EXHAUST MAKING A STRANGE SOUND, SO SHE SHUT THE ENGINE OFF AND WE HAD THE CAR TOWED TO THE DEALERSHIP. A COUPLE OF DAYS LATER, I GOT A CALL FROM THE STUDIO EXPLAINING THAT THE CAR WAS VERY LOW ON OIL AND THAT IT APPEARS THE CAR'S BEEN CONSUMING OIL AT AN ACCELERATED RATE. HE SAID THEY PERFORMED AN OIL CHANGE AND THAT, PER FIAT'S PROTOCOL, THEY'D PERFORM AN OIL CONSUMPTION TEST BY LETTING US DRIVE THE CAR FOR 750 MILES AND THEN WE'D HAVE TO BRING THE CAR BACK TO LET THEM CHECK EVERYTHING OUT. I WENT TO PICK UP THE CAR ONLY TO FIND THE SAME ISSUE THAT MY WIFE HAD DESCRIBED (ENGINE SHAKING, EXHAUST MAKING NOISE). IT WAS LATE AND THE SERVICE DEPARTMENT WAS CLOSED, SO I LEFT THE KEY WITH THE RECEPTIONIST AND EXPLAINED THAT THE CAR WAS IN THE SAME CONDITION AS WHEN WE HAD IT TOWED AND THAT I'D LIKE THEM TO FIND OUT WHAT'S GOING ON. A FEW DAYS LATER, THE STUDIO CALLED TO EXPLAIN THAT THE ENGINE'S OIL PRESSURE WAS SHOT AND THAT THE ENGINE NEEDED TO BE REPLACED. CYLINDER 3'S OIL VALVE WAS STUCK AND THE CYLINDER WAS MIS-FIRING. THE STUDIO RECOMMENDED REPLACED THE ENGINE AS OPPOSED TO INVESTIGATING WHAT FAILED, SINCE THE INVESTIGATION COULD TAKE HOURS AND COST MORE THAN AN ENGINE REPLACEMENT. THIS IS MY SECOND FIAT; THE FIRST EXPERIENCED THE CLUTCH RECALL THAT I HAD PREVIOUSLY REPORT TO NHTSA AND THANKS TO MINE AND OTHERS REPORTS, A RECALL WAS ISSUED.

I WAS DRIVING TO AN APPOINTMENT AND WAS SITTING AT A RED LIGHT WHEN MY FIAT BEGAN TO SHAKE. I TOOK IT TO THE FIAT DEALERSHIP AFTER MY APPOINTMENT ON JUNE 16, 2017. THE FOLLOWING TUESDAY THEY SAID I WAS MY SPARK PLUGS AND I APPROVED CHANGING THEM. WHEN THEY STARTED THE CAR AGAIN THEN THEY GOT A MESSAGE STATING NO COMPRESSION IN CAM 2. I AN THE ORIGINAL OWNER AND HAVE HAD THE CAR JUST UNDER 4 YEARS. I HAVE HAD ALL THE SCHEDULED MAINTENANCE DONE THERE AT THE DEALERSHIP. I HOWEVER HAVE 54K ON THE ENGINE SO I AM JUST OUTSIDE OF THE WARRANTY. I HAVE BEEN GOING THROUGH VARIOUS FIAT FORUMS AND SEE THAT THIS SEEMS TO BE AN ISSUE WITH CAM 2.

I HAVE RECEIVED SEVERAL RECALLS ON MY CLUTCH. I TOOK IT TO MY DEALERSHIP AND THEY WERE MADE AWARE OF THE ISSUE JANUARY 11TH, 2017 AND THEY STILL HAVE YET TO CONTACT ME. ALSO I HAVE AN OIL LEAK IN WHICH THEY SAID THEY FIXED. RIGHT AFTER I TOOK IT HOME OIL HAS BEEN FLOODING OUT OF IT AND SPRAYING ALL OVER MY CAR. THIS SHOULD NOT BE A PROBLEM GIVEN MY MILES AND YEAR OF MY CAR. I GOT ALL OF THE NECESSARY OIL CHANGES BUT HAVE NO PROOF SINCE MY HUSBAND DID THEM HIMSELF AND PAID CASH FOR THE ITEMS HE NEEDED. SO THE DEALERSHIP IS REFUSING TO WORK WITH ME AT ALL WITH THIS ISSUE EVEN THOUGH THEY MADE THE OIL LEAK WORSE THEN IT ORIGINALLY WAS.
