2020 Audi Q3: engine stalls while driving

Filed Jan 8, 2026 · Fuel system · FL

I purchased my 2020 Audi Q3 in August of 2020. I am submitting this complaint regarding the recurring and unacceptable issue with my Audi. In February of 2023 my vehicle started shaking and stalled while driving. I could not restart for awhile, after a few minutes it restarted. I took it to Audi and they verified that the output of fuel pump did not meet minimum flow. They replaced the pump. Then in November of 2025 my car stalled again, doing the same thing, after a few minutes it would restart but kept intermittently stalling. This Fuel Pump malfunctioned again, and now this time both of them were not working properly. Both the High Pressure and Low Pressure Fuel pump was replaced again in January 2026. Having to replace a major component like the fuel pump twice on a 2020 luxury vehicle is unreasonable and deeply concerning. A fuel pump failure is not a minor inconvenience, it affects the reliability, safety and drivability of the vehicle.

After stopping at a sign on a busy road, the engine fully shut down after a second or two of acceleration. A warning came on the dash to pull car over and call dealer. The engine was completely dead, but I was able to coast to side of road. After thinking about the situation for a few minutes, I started up the car again since I was in a precarious location. I drove it another ten miles to my destination without any issues. After reaching my destination, I called audi roadside assistance. They sent a tow truck (it took just under four hours to arrive). They then towed car to elk grove audi, which is when I learned that audi knew of this problem but was not updating the software until problems developed in the cars. I feel that I was very lucky that the stalled engine did not happen on highway or that I did not have any passengers in car. The outcome could have been very bad. After contacting audi customer service a few days later, they ('maria' on message line) said they would look into the issue and contact me by friday feb 12. I never received any further communication from audi.

Drive system malfunction- 05dec2020 as I was driving on the city street (35mph) the speed stalled(decelerated) at 12mph, I pressed on the accelerator pedal all the way down in order to increase the speed but will not increase. I pulled to the side and stopped and then turned off the vehicle. I waited for about 5mins then restarted the vehicle. Drive system malfunction alarm cleared afterwards; I was able to accelerate to the speed of 35mph. The vehicle returned to normal operation state.

I now have a brand new car for 4 weeks..on 5 separate occasions, the start/stop feature on the vehicle has presented a major problem...it stalls episodically when the brakes are applied...it stops but then does not start. The worst was pulling into an intersection, stopped to look for oncoming traffic...before I saw a car was heading down the hill, I tried to pull out but the car stalled and now oncoming traffic was bearing down on me.. I brought the car to audi service, they told me audi knows about the problem but has no fix!!! Incredible! This is a major safety issue that is not being addressed. I was told by the service manager to override the start/stop feature to deactivate...it is now incumbent upon me to remember to do this every time I start the vehicle. Audi has a problem with this vehicle which has now become my problem. I am told that they have "no idea" when this will be fixed...are they kidding me...this problem has the potential of causing a major vehicle crash. This must be addressed and rectified. Please advise.

I bought my 2020 q3 sline premium on august 15, 2020. The vehicle had stalled twice, first on august 17, 2020 and second on august 20, 2020. In both cases, the engine stopped as soon as I stopped in auto with my parking brakes engaged. The display screen also went dead/blank in both cases. In both cases I had to restart before I can drive. I also notice that when stopped and the auto stop engages the steering wheel locks making it difficult to turn a corner from a red light. Additionally, while driving the car identifies tar on the road as lanes and jerks the car away and it is very difficult to pull the steering back.

When accelerating the vehicle jerks like it is losing power. It has done this on both the interstate and on regular roads in motion. I have had to pull to the side of the road in fear that the vehicle will stall on me. On several instances I have been driving the vehicle and several warning lights show up and then it will not accelerate at all. Thankfully I have been able to roll off of the road each of these times. Theres no warning or any indicators that come up prior to the car completing dying in the road. I took the car to the dealership and was told theres software issues but nothing they can do for it until an update comes out. I was told to turn off the auto shut off feature and it will work ok, but that has not helped. The vehicle is unsafe to drive because it could completely fail at any given moment without notice. After further research this is a known issue with 2020's. It has been going on for the past month 1/2

My life was almost taken away by my cars engine failing in the middle of making a left turn on a 4-lane road where traffic is going 50 MPH. When it stalled, the engine just quit leaving only electrical (lights & media) working. I felt I was trapped as a car was headed right for me and I could not even increase speed because the whole car just seem to not move forward. I eventually pulled into a median, but nonetheless I am scared to drive this car. Much like the person who also reported this issue.

I leased my audi q3 2020 on 04/30/2020. The main issue happened recently where I was driving on a busy boulevard doing about 50mph and the engine stalled leaving only the electrical components working. I managed to pull the car to the side with my hazard lights on but had oncoming traffic doing at least 60-70mph. I felt in danger and that this could have been a grave accident. I brought the car to audi who says it's in need of a software update, they do now know when it will be available but would be in the 3rd quarter of 2020. They will call me to being my car back in for the update when available. They deemed it safe to drive, did not offer a courtesy vehicle or rental. I explained I do not feel safe and even made a report to audi of america without any help. I have a 1 month old car that I feel is going to put my life and the lives of people around me in danger if this should happen again. They did not leave me with any choice other than to take the car back because I need to get to and from work. I explained that should the car be damaged, I be injured or worse that they are liable given that I brought the car in and the issue was not resolved. I see this report has been made multiple times and I can say this is a very scary situation to happen at full speed with many cars around you. I have also had multiple alerts saying driver assistance malfunction. I also notice that when stopped and the auto stop engages the steering wheel locks making it difficult to turn a corner from a red light. Additionally, while driving the car identifies tar on the road as lanes and jerks the car away and it is very difficult to pull the steering back.

The vehicle stalls for no reason while being driven. Audi has advised us that they do not have a fix for the problem. Apparently it is a software issue but the software is not available yet. My wife was driving down the road yesterday and the car suddenly stalled. The vehicle was in the shop for 5 weeks when it was first purchased due to multiple electric malfunctions.

While driving my 2 month old audi q3 this morning the car completely stalled while going approximately 40 MPH. I received an error message, drive line malfunction. The car would not respond at all after applying the accelerator. I was almost hit by 2 trucks!!! I then put the car in park and it was able to start it up. I brought it to the dealer, they just called me and told me they found an error code p060c00 indicating an internal control module problem. They said that there is no known fix at this time but they said that there is a known service bulletin on this issue. They said that I need to disable the auto start stop feature on this car each time I start it up. What do I do now? My wife will not drive this car anymore and does not want me to drive it either! This is not a safe car to drive. Please help!
