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.

They said it doesn't exist so there is nothing to fix. The car was sent to the Fiat dealership in Henderson for a few days and they said it didn't flash while there so Fiat, Chrysler and Tobin Fiat of Las Vegas saw it as a none issue or as a customer complaint about nothing.

Car engine died then cranked up on its own while driving 60mph stating high temp (pull over, turn engine off) - had been in the car less than 1 minute, just long enough to get to 60 on the highway. Now clutch interlock, and brake interlock must be replaced.

I was driving a total of 4 and a half hours back home from a trip. Most of the trip was via straight freeway. I was 2 hours in when the check engine light started blinking. I called my dad who said to pull over immediately. I let my car glide through the exit that was coming up and I noticed smoke flowing behind my car. I pulled over and got out to see smoke coming out of the hood. I opened the hood and discussed what was happening with my dad. All of a sudden I heard a noise that sounded like a blow torch and flames came up out of the engine. I ran about 50-100 meters away and called 911. Quickly, the whole hood was on fire. Thankfully the fire department must have been close by because they were able to put out the fire before it got too far inside the car. The windshield melted and shattered. I found glass stuck on my purse and hat sitting in the passenger seat. I had to throw them away as I could not get the glass off. The car was taken to a tow yard where my insurance company inspected it. They could not find the cause for the damage. Since the car was a 2015 model that I had purchased new and it was 2018, I thought it was strange that this would happen so I had fiat pick up the vehicle and inspect it. They said they did not find that the fire was associated with manufacturing or assembly error. I then had my insurance company take it and close the claim. Still find it strange that a 3 year old car suddenly caught on fire with no warning. I'm glad I was able to move off to the side and that I wasn't in the car when it caught on fire fully. The cause of the fire though is still unknown.
