Periodically, when trying to accelerate, the car stutters as if it's not getting any fuel and the check engine light will flash on briefly, then go off, and keep flashing on when pressing the gas pedal. It will continue to do this until you stop, turn the car off, open then close the door, let it set for about a minute, start the car again, and you HAVE to turn off the Automatic start/stop. Once you do that, and continue to keep turning off the auto start/stop every time you start the car for a few days to a week, it will resolve the issue for about a few months (or shorter if you drive frequently to where the auto start/stop is activated more frequently). -Engine? -Fuel Injection? -Automatic Start/Stop The car stuttered and acted like it was going to shut off while driving down the road. This could have caused an accident or even caused irreplaceable engine damage. It has not been reproduced or confirmed by a dealer or service center because it is random and once you shut the car off and the auto start/stop, it resolves the issue for a short time. I have called the dealer and I have called VW company to report the issue, but they both just refer me back to the other. No, the vehicle has not been inspected. No symptoms or warning lamps. The check engine light only comes on after the car stutters and struggles to accelerate for a few seconds, then it will flash on and off depending of if I am pressing the gas pedal.

2 instances occurred where the auto start/stop initiated in the midst of driving resulting in a stall and required the car to be restarted in order to start driving again. One time occurred while backing up and another while taking a turn both at low speeds. There was a recall on 2021 Volkswagen Taos’s for the same problem. I brought the car to the dealership to be assessed and the car remained in the service lot from 7/6/23 to 7/17/23, however the problem could not be recreated. Thus the car was returned to me without any solution. I clearly stated to them that I am picking up the car against my wishes as no solution was found and this has been extremely dangerous almost causing accidents.

While stop at red light on 2 occasions, the car goes into the auto stop start feature. The light turns green and I depress the accelerator to start to drive and nothing happens. I frantically try to determine what's going on my, shifter is in Drive and nothing. I press ignition to start and it states car in drive. Shift car to park and car starts. This all occurred after VW did Campaign #24IR. This is dangerous since if people don't realize your not moving they can rear end you or go backwards on a hill.

I purchased my VW TAOS on Nov 26, 2021, and since then I have experienced faulty issues 4 times. 2022 Jul twice, Sep once, and Nov once. When merged to the main road the car refuses to accelerate and gives strange sounds in transmission/engine area. The first 2 times I had the issue with loss of power and significant lag in acceleration I could see the "start/stop error" message in the dashboard, and I had to pull over to the side of the road. I drove in the parking lot nearby for few minutes and continued driving when the engine seemed OK, but the automatic engine start/stop system failed to work on traffic lights when car fully stopped. I notified my local dealership about this issue and got an appointment for inspection in August. When examined they recommended changing my fuel to premium and explained that the fault was caused by the quality of gas I put. I followed their instruction and only been pumping Unleaded-91 Premium grade fuel for the last 2 months, but I had a more serious issue in mid-September. In the middle of traffic at 40mph speed a sudden loss of power occurred followed by a check engine light flashing. Again, I had to make an emergency stop from the second lane to pull over into the shoulder. When I notified this to my dealership, they recommended to get the car checked during my first oil change that was supposed to happen a month later because when I consulted with the operator, they said I should observe if the problem is going to reoccur. On 7th of Nov 2022, I got my oil changed for the first time at the dealership and drove my car for a while and it seemed fine. However, by the evening when I tried to drive it back home the same issue with worse noise in the engine area took place and car failed to accelerate in the middle of the traffic where I had to act quickly to pull over to the side of the road causing risky situation to other drivers on the road and myself. I am now convinced that this issue is never going to be fixed.

Purchased vehicle new from dealer on 5/25/22. Auto Start/Stop feature was enabled while driving on 6/8/22. Stopped at light and vehicle shut off as it should have with feature enabled but then would not start again. Had to put car in park and restart while sitting in the middle lane of a busy road. Had error message advising to restart manually come up on dashboard. Reported problem to dealer where purchased. Auto Start/Stop feature was enabled while driving on 10/27/22. Stopped at light and vehicle shut off as it should have with feature enabled but then would not start again. Had to put car in park and try restarting. This time I had to try to restart approximately 4 times before car was running again. This happened while sitting stuck in the middle lane of a very busy road again. This time I was very concerned about getting hit so I did not even notice if the error message about starting manually came up on the dashboard. I was busy putting on hazard lights and looking for cars that may hit me and trying to re-start car. Since incident first time in June - about 85-95% of driving time I disable Auto Start/Stop feature for fear of this happening again. Therefore it could have likely happened many more times between June and October if the feature had been enabled while driving. This vehicle does not have AWD. I will report to dealer but I see many others seem to have same or similar problem with this 2022 Taos so I wanted to report here as well. Thank you.

I had a check engine light, epc warning, lane assist deactivated and stop start disabled all at once while on a drive in a remote area without cell service. The car had a dangerous loss of power. I brought it to the dealer and they told me there is no fix as its a common software issue that apparently faulty detects bad gas. All they could do was reset the code and say it may happen again, and recommend higher octane fuel. VW corporate was no help & I opened a buyback case. I don’t trust this car and dont think its safe to drive. This is the second time brought in for a stop start stall issue. Under 4k miles.

When pressing on gas peddle, vehicle aggressively jolts forward. This caused me to almost rear end the vehicle in front of me while on the highway as well as be rear ended. While on and in drive Taos appears to have died. Vehicle will not drive and break locks. The break peddle has also locked up twice while driving. Check engine light did appear but shortly turned off. Auto start/stop does not work on app and auto start doesn’t work on key fob either. Multiple times my Taos has “detected” a vehicle in front of me and flashed a warning when there was no vehicle at all. These incidents have occurred over multiple days. At this time I have only owed my Taos for three weeks.
