Engine reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

My car keeps going into limp mode seasonally, it also emits bad odors when given throttle, and it is definitely lacking power. Situation has also caused a misfire on my 3rd cylinder and a super rough idle and start

Vehicle completely lost power and quite running in the middle of the desert in Arizona. This relates to Saftey Recall 93c. I had to have the car towed and repaired in Scottsdale, AZ. I have been told that this repair (which was expensive) might not remedy the problem and it could reoccur. It's been over six months since the recall was issued and yet no remedy is available and I have not received reimbursement for the repairs I had to have done to get my vehicle running. I think six months is enough time given that I cannot trust the reliability of my vehicle due to this serious problem. When a vehicle just "turns off" in the middle of the freeway it poses a huge safety risk both to the occupants and to other drivers in the area. So my complaint is that it's taking far too long for Stellates to produce parts to remedy this problem.

I was driving on the highway and my car starts sputtering, I figured I pull over and turn my car off and on. My car seemed fine and I continued to drive home from work. As soon as I got off the highway my car completely shut off mid ride, stalls out and my steering wheel locked up. I was able to get my car turned back on and get back home. Filled with anxiety at least. Luckily I have a code reader in my car as soon as I pulled into my driveway and the codes showing where P008A which is directly related to a fuel pump/ fuel delivery issue. This happened on February 28th. I have been scared to drive the car since

the vehicle has read off warnings seconds from simply stopping and cutting off in traffic. this has happened at least two times now. it may say full throttle service and flash lights before simply slowing down and the check engine light flashing while on the highway unable to speed up no matter how far down on the gas pedal I push. has been taken to dealer several times. problems started soon after purchasing vehicle. On 3/1/2026 while leaving church service, my family and I were on a major highway with the speed limit at 65 mph. The vehicle just slowed down without giving any power and could not get it up to the speed to continue with traffic. This vehicle could put me and my family at risk for a possible dangerous situation.

I am filing a complaint in regard to recall 93c for my 2017 Alfa Romeo. The dealership/manufacturer has failed to provide me with a fix, parts or even just a loaner car due to the safety hazard. My car has gone limp mode several times on the highway at speeds of 70mph. This is unacceptable.

My 2017 Alfa Romeo Giulia, VIN [XXX] , is currently disabled and inoperable at the authorized dealer, Alfa Romeo Fiat of Daytona (Service Advisor: Kevin Chapman). The vehicle is subject to the active and known Safety Recall 93C (Low-Pressure Fuel Pump). My vehicle is experiencing a total loss of motive power and engine stall, which is the exact safety hazard described in the recall. Furthermore, the initial failure of the low-pressure fuel system appears to have caused secondary consequential damage to the expensive High-Pressure Fuel Pump (HPFP), and the vehicle is also exhibiting a severe and recurring electrical defect (new battery dying, random dash warnings/brake lights flashing). The manufacturer, FCA/Stellantis (Customer Care Case #XXX...), and the dealer are engaging in a runaround to deny basic safety recall provisions: 1. Refusal to Cover Consequential Damage: FCA Customer Care stated that if the issue is 'not the 93C recall then it will all be customer pay,' which conflicts with NHTSA guidelines requiring the manufacturer to remedy the primary defect and all damage proximately caused by it. 2. Refusal to Provide Loaner/Rental Car: FCA stated the loaner is up to the dealer, and the dealer stated it is up to the diagnostic. This runaround has created an unreasonable delay in the repair of a federally mandated safety recall, leaving the owner without transportation for a disabled, unsafe vehicle. I am requesting NHTSA intervention to compel FCA/Stellantis to: a) Authorize a complimentary rental car/loaner until the vehicle is fully repaired. b) Provide a formal commitment that all damage proven to be a direct, proximate consequence of the 93C fuel pump failure will be covered at no cost.

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

Multiple times the check engine light will come on while driving. It shuts engine down at any speed. This usually happens during warm up phase of vehicle. You have to pull over and cycle power off and on multiple times before it starts and runs again. It has stalled in intersections causing traffic delays. Once it starts and codes clear it typically runs fine for long periods. Symptom codes include throttle system failure, fuel pump low pressure, miss fire, bcm communication error. Cycling off and on clears codes and car operates normally until next cold start. Symptoms seem to worsen when driving in n or a mode. Symptoms seem to worsen when remote starting vehicle.

When I'm driving on the highway, the vehicle suddenly have a notification stating 'Service Electronic Throttle Control' and started to lose power, no matter howbjard the pedal was being depressed, it's notbgiving enough power out and start dropping speed. That drop me almost hit the vehicle behind me and inposing a serious risk because I'm on the highway. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the dealer mentioend it might be a fuel pump problem. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, it start almodt everytime suddenly from nowhere. Usually it will be ok after a few restart, but this t.ime it's persistent

Hello, I was driving in the highway at highway speed and my engine shutdown with any sort of warning. I almost caused a huge accident. After I took it to the Alfa Romeo dealer, I had to replace the fuel pump according to the dealer, which is a common problem. I think Alfa Romeo should do a recall on the fuel pump. I also,scratched my car due to this incident avoiding a bigger accident. This car needs to be recalled for fuel pump repairs for all the car with the old bad fuel pump design. Thank you

When driving vehicle it randomly goes into Limp mode and gives an “electronic throttle module error”. This in turns decreases the power of the vehicle significantly and causes you to move over lanes as to not cause traffic. This issue is common for a lot of Alfa Romeo Guilia owners.

Engine recently began making a loud ticking sound, that everyone who heard it asked, "What's wrong with your car?" I purchased the vehicle new 5.5 years ago and it presently has 38,475 miles on it. The dealer determined the noise was due to a loose oil pump bolt under the timing cover. It was a 10.5 hour repair to remove a bolt and reapply lock-tite to it and then reinstall. Had the repair not been performed the bolt could have vibrated all the way out and caused internal damage to the engine, which I believe is a safety issue. The repair cost was $1,813.68. Per the dealer this was the first Giulia model that they had to service for this issue, but they had serviced several Stelvio models that were newer but shared the same engine. In today's automotive market such repairs should not be necessary on a vehicle with low mileage. The brand offers a 4 year / 50,000 mile warranty, but not a separate powertrain warranty. In hindsight, it appears the brand does not have a great deal of confidence in the durability of the powertrains it builds.

On August 18, 2022, I was driving the vehicle at a speed of approximately 45 mph when the vehicle motor suddenly and without any prior warning completely shut down. Several warning lights appeared immediately but none prior to the shutdown. I was driving in moderately heavy traffic and had to coast to a spot off the shoulder of the road. This was a dangerous situation and if I had been in heavier higher speed traffic, this would have been a very risky safety situation since I had no power whatsoever to control the vehicle movement. The vehicle would not restart and had to be towed to a repair shop. The problem was with the Fuel Pump Control Module which had to be replaced along with replacing the fuel pump. The manufacturer had previously issued a Technical Service Bulletin (TSB) concerning this but had not issued a recall. I was unaware of the TSB. The manufacturer was obviously aware of issues with the Fuel Pump Control Module but did not issue a recall for vehicles. The TSB was for cars produced prior to August of 2017 and my car was produced in May of 2017.

Car started itself. Vehicle was sitting in garage and was Locked. The radiator fans came on and vehicle started on its own. it continued to run until we unlocked and hit the stop button. Since this has happened it does not turnover on the first attempt. It has set several codes, Start stop unavailable, service electronic throttle, service engine now. My concern is if the vehicle were to start in the garage while we were asleep and carbon monoxide would leak into the house.

The brake by wire system failed, and another component caused the vehicle to accelerate when I hit the brake pedal. I didn't have any proof on the last complaint, but I have it now. This brake failure caused me to rear end someone, which caused a multiple vehicle accident. The dealership I took it to was aware that I was having electrical issues with the car, but they said they couldn't do anything about it because they couldn't find any fault codes. I even sent them a video of it as well. I also believe this car was involved in a prior accident as well by one of the previous owners and fixed by one of them under the table, because the front bumper shock absorber plate broke in half, and had writing on it as well that looked like something a repair shop would do. This car is unsafe.

My Alfa Romeo only has 29,000 miles on it. It randomly dies on you and does not start. Might happen while you drive with the start/stop and also when you try to turn on the car. When speaking to an Alfa Romeo representative, they inform you that to fix it’s about $600 or higher and they are also aware that is a common problems with their cars. The representative informed me that to turn it back on, I have to disconnect the a wire on top of the battery. I’m not a mechanic and should not have to work with the electrical system of the car. After reconnecting that wire, there’s the electric stability control light that turns on and the steering wheel assist light turns on. It’s crazy that this is a know issue with these cars and the dealers try everything they can to charge you for that repair. Which makes the car completely unsafe.

While waiting for a traffic light to change, the vehicle turned off but immediately turned back on. About four miles later, the same situation happened again but this time it took me a few minutes to get it to start. The vehicle had 1/4 fuel on the tank. After refueling, it drove fine. It was fine again on my way home from work, at least most of the way. When I was near home, it started to shut off and back on at a few traffic lights, but was able to drive it home.
