Fuel/propulsion system

24 reports3 crashes
“Dear NHTSA, I am writing to report a serious safety incident involving my vehicle. On [XXX] at approximately [XXX], while driving to an extracurricular activity for my [XXX] child, my vehicle displayed the following warning messages: “Service Engine,” “Service Electronic Throttle Control,” and “Start/Stop Unavailable.” Immediately after these warnings appeared, the vehicle shut off and shifted into neutral. I lost the ability to steer, creating a highly dangerous situation. I was on a busy road approaching an interstate entrance and had to react quickly to avoid a potential accident. Fortunately, I was able to maneuver the vehicle safely to the side of the road, but I believe this malfunction presents a serious risk to public safety and should be investigated. Please let me know if additional information or documentation is needed.”

Engine

23 reports3 crashes
“This has been an issue slowly getting worse over the last few months and escalated this week. June 20th, 2025 my car has literary died over (4) times during traffic and I had to try and stay calm while using a code reader to clear the codes to get the engine to start. Very scary, I have a 2017 Giulia Ti that just hit 100k miles. Even took it to the dealership and they couldn't explain it. Parasitic draw on my battery and they gave it a pass :( Codes: P2510-ECM/PCM POWER RELAY SENSE CKT RANGE/PERFORMANCE P0103-VAF CIRCUIT HIGH INPUT P0100- VAF CIRCUIT MALFUNCTION P0451-EVAP SYSTEM PRESSURE SENSOR/SWITCH 'A' RANGE/PERFORMANCE P0106-MANIFOLD ABSOLUTE PRESSURE/BAROMETRIC PRESSURE SENSOR CIRCUIT”

Service brakes

6 reports4 crashes
“On July 10 I was driving my car and then suddenly all the brakes came on. There were no objects in front of the car or behind the cars it was early morning at 7 o'clock on my way to the hospital for work. There was no warning that there was an object in front of me or anything. Two days later around the same time in the morning the car could start but the electronic brake system was ON. you can't turn them off. it gave a temporary message about electronic brake system issue. you can start the car and turn it off but the car won't move the even when you put the gear on as if all electronic brake system are engaged and can't turn them off by pushing the electronic parking knob off. after turning the car on and off multiple times, this electronic brakes must have been disengaged. Three days later the car was diagnosed with brake caliper failure in one tire which was repaired. I'm a physician and by no means a car technician but I think these are two completely unrelated issues. I feel that a bad brake caliper in one tire should not cause all four tires and all four brakes to stop the car suddenly on the road or prevent the car from moving when Idol or lock the…”

Electronic stability control (esc)

5 reports1 crash
“THE CAR STOP BY ITSELF IN THE MIDDLE OF THE ROAD AND I JUST COULD MAKE IT TO PULL IT OVER AND LIGHTS APPEAR ON THE CAR DASHBOARD THE CHECK ENGINE, THE ELECTRONIC THROTTLE CONTROL, AND OTHER LIGHT THAT I DONT KNOW WHAT IT IS BUT IT WAS AN "A!" . I TURN OFF THE CAR AND I WAITED FOR 10 MIN AN I TURN IT ON AGAIN AND IT WORKS BUT THE LIGHTS STILL WERE THERE, SO I TOOK IT TO THE DEALER SHIP BECAUSE I HAVE ONLY 4 MONTH WITH THE CAR AND IT IS AN USED CAR, BUT IT HAS ONLY 19000 MILES TO HAVE THAT KIND OF PROBLEMS. AT THE DEALERSHIP THEY TOLD ME THAT THEY DONT HAVE SPACE TO CHECK THE CAR PROBABLY UNTIL OCTOBER THAT THEY WILL CALL ME, BUT WHEN WE WENT BACK TO HOME THE CAR DID THE SAME IT START TO DROP THE SPEED BY ITSELF AND STOP , AND I JUST PARKED IN MY HOUSE AND I HAVE NOT MOVE IT, THE CAR HAS OTHER PROBLEMS TO CHECK, THE HOOK CONNECTIONS AND THE TIRES, BUT THE THING IS THAT THE DEALERSHIP SAY THEY HAVE TOO MANY CARS IN FRONT OF MINE AND THEY WILL CHECK IT PROBABLY UNTIL OCTOBER 2020. I REALLY THINK THOSE VEHICLES ALFA ROMEO GUILIA SHOULD BE CHECKED FROM THE ELECTRICAL SYSTEM BECAUSE LIFE OF PEOPLE IS IN RISK WHEN THEY JUST STOP IN MIDDLE OF THE ROAD.”
