Audi A3 stalling problems

Filed Sep 24, 2026 · Brakes, Electrical · CA

On XXX while driving my 2024 Audi A3 at highway speeds on a live freeway, the vehicle suffered a sudden and catastrophic electrical system failure. The dashboard immediately displayed critical warning indicators, including "Electrical Malfunction" and "Battery Malfunction” and “Drive system Malfunction.” Without further warning, the vehicle's engine completely stalled and shut down while moving in active traffic. Due to the total loss of electrical power, the vehicle immediately lost all power steering assistance and power braking assistance, causing the steering wheel and brake pedal to severely stiffen and become nearly unresponsive. I was forced to navigate a rolling, unpowered vehicle across highway lanes without steering or braking assistance to reach safety, creating a severe and life-threatening hazard to myself, my [XXX] son that was in the vehicle and other motorists. The vehicle currently has approximately 60,000 miles. This sudden shutdown mirrors the well-documented Belt Starter Generator (BSG) and alternator manufacturing defects that Audi has previously acknowledged and recalled in other model lines, but which are clearly actively failing in 2024 model year vehicles as well.

The contact owns a 2015 Audi A3. The contact stated that the dealer had previously repaired the vehicle under the federal safety agency Campaign Number: 24V110000 (Fuel System, Gasoline); however, the vehicle was not driven until a year later after the recall repair due to medical issues. The contact stated that while refueling the vehicle, fuel was backing up in the fuel filler neck. Additionally, while driving at an undisclosed speed, the vehicle stalled and failed to exceed 30 MPH. There was a fuel odor coming from the vehicle, and the fuel and check engine warning lights were illuminated. A family friend diagnosed the vehicle and determined that the suction jet pump had failed. The dealer was made aware of the failure. The manufacturer was notified of the failure by phone and email.

In August 2025, my 2017 Audi A3 (VIN [XXX] ) experienced repeated stalling, strong gasoline odors inside the cabin, and a check engine light immediately after Audi completed recall-related service. The safety issue was later confirmed by the dealership to be caused by a failed suction jet pump (the federal safety agency Recall 24V110), which allowed fuel to enter the EVAP system and leak into the rear seat area and cabin. The leak was so severe that the rear seat and flooring had to be replaced due to fuel saturation. Before the problem was properly identified, I was repeatedly told the issue was “just the gas cap,” despite reporting fuel smell, rapid fuel loss after filling the tank, and the check engine light. During this time, I unknowingly drove a vehicle with a significant fire hazard. The cabin fumes caused physical symptoms and unsafe driving conditions. I was not notified of this recall at the time I purchased the vehicle in March 2022, nor was I notified of a second recall affecting the passenger occupant detection system (69BY), despite having purchased a one-year maintenance warranty. I only became aware of the recalls after experiencing the hazardous symptoms described above. The problem was confirmed and reproduced by the Audi dealership. Fuel odor, fuel loss, and warning lights first appeared within 24 hours after the initial service visit, and the safety defect was later linked to the recall-related component failure. This defect presented a serious risk of fire and exposure to gasoline fumes to both myself and other road users.

Shortly after starting the car, and while exiting a parking lot, the car stalled and lost engine power. I was able to start the car back up for long enough to be able to pull back into the parking lot however after the car got parked the engine refused to start and stay running for the next hour. After a check using OBD11, the codes were showing the cause of the original problem was low fuel pressure which ended up causing misfires. The only way I was able to get the car running and staying running was by purging the system repeatedly by turning on the ignition without starting the car. This has all happened once before while I was driving at relatively low speeds (around 25 MPH) in a town, and I had to go through the same process. No warning lights show for the first multiple attempts at starting the car until it consistently fails to start. No inspections have taken place.

This is in regards to your investigation into a recall for Audi 2015 A3 fuel system issues. My car was repaired as part of that initial recall, however, i am experiencing a bunch of fuel related issues as of now. My fuel tank will no longer fill with gas. The dealership said i need a need fuel tank. Then at the exact same time, my low side fuel pump failed. I mentioned to the dealership about the recall and the fuel problems, they told me they were not related. I paid to replace the lower said fuel pump. Now a few months later my high side fuel pump has failed. I then found the article about the investigation about fuel issues, they told me again it was not related. So now they are asking me to replace the high side fuel pump. I told them it was not a coincidence that both fuel pumps and my gas tank all fail at the same time along with the investigation. They again told me its not related. I opened up a case with Audi of America and they are investigating. Having issues with the fuel delivery system will cause the car to sudden stop and stall at high rates of speed, and has caused me to break down in the middle of the road with no warning.

Transmission module! Started jerking when switching gears, to not switching gears at all and this happened while driving so I was on the road stalled with no gear changes! Car is inoperable, due to this and it’s still being paid for yet not able to be driven from practically the day I bought it! The manufacturer knows this is an issue and we are still out here in unsafe non gear changing cars! Very dangerous
