2022 Volkswagen Taos: misfire or rough idle

Filed Sep 22, 2026 · Engine, Fuel system · CO

A recurring fuel-odor and drivability problem began while the vehicle was under manufacturer warranty and was never permanently resolved. In September 2022, a Volkswagen dealer documented code P2421 for an EVAP system vent valve stuck open and performed a software update. In June 2024, another Volkswagen dealer documented a strong fuel smell intermittently entering the passenger compartment but found no leak and made no repair. In April 2025, the vehicle was reported to sputter when accelerating from a stop. In July 2025, fuel odor at startup, poor fuel economy, and slow acceleration were again reported, but no leak was found and the vehicle was declared to be operating normally. In June 2026, the vehicle developed an EPC warning and codes P0316 and P0302, resulting in diagnosis of a cylinder 2 injector problem. In September 2026, another repair facility documented continued gas smell, hesitation, possible misfire, cold-start code P0316, and a damaged intake-pipe O-ring causing an air leak. Fuel odor and drivability concerns continued. On September 22, 2026, Volkswagen Customer CARE advised that the vehicle should not be driven until the fuel-leak concern is resolved and instructed that it be towed to an authorized Volkswagen dealership. My concern is that a potentially safety-related fuel/EVAP and drivability defect was repeatedly reported over several years but was never permanently identified or corrected. That wording tracks the records in your packet: the 2022 P2421 EVAP finding, 2024 cabin fuel odor, 2025 sputtering, 2026 P0316/P0302, the damaged intake O-ring, and VW’s later do-not-drive warning.

On July 30, 2026, while driving my 2022 Volkswagen Taos out of my apartment parking lot, the EPC and check engine lights illuminated. The vehicle shook, lagged, stalled, and could not accelerate normally. I parked and turned it off. An authorized Volkswagen dealer diagnosed a faulty spark plug. On August 12, the same failure recurred. The EPC and check engine lights illuminated, the vehicle shook, and it again lost acceleration. The dealer attributed the misfire to poor fuel caused by Arizona monsoon and dust-storm conditions and added a fuel additive. However, the only major dust storm around these dates occurred on August 19, after the first two incidents. No fuel-test results were provided to support this explanation. On August 20, the failure occurred a third time while I was driving on a major road. The vehicle shook and experienced a severe loss of propulsion and acceleration. The check engine light remained on after the engine was turned off. I had to restart the vehicle three times before I could move it into a parking lot. I was less than one mile from entering a highway, and the sudden loss of acceleration in traffic created a serious collision risk. The vehicle was towed to the dealer. On August 21, the dealer again attributed the misfire to poor fuel. It added fuel-system cleaner, filled the tank with 91-octane fuel, and test-drove the vehicle, but the misfire remained. The technician then reported that three spark plugs were fouled and required replacement. The same dangerous loss-of-power condition occurred three times within 22 days despite two prior repair attempts. The cause of the repeated misfires and fouled plugs remains unidentified. The vehicle is at the Volkswagen dealership and is available for inspection. There was no crash, fire, or injury.

The systems failing are electrical, engine, and fuel/propulsion systems. VW TAOS 2022 purchased Sept. 2023. Two weeks after purchasing the vehicle, I'm driving down the street and the vehicle began to lose power and start slowing down. It eventually cut off. About a week later, I experienced the same issue. I called the dealer and they had me to bring my car in. I was told that they couldn't find the problem, but that the car was misfiring. They "repaired" and returned it to me. As I drove on local streets and the interstate, I have problems with acceleration. The car does not pick up speed like it should and lags behind and then suddenly jerks forward (even after battery rest times during a stop). It rides a bit rough. Occasionally, my dashboard blacks out while I'm driving. My auto-start doesn't always work, even after the fob batteries have been changed. My gas seems to disappear and I find myself gassing up more often than I should be. I would contact the dealership, they'd coordinate service around my scheduled service dates and claim that they could never find or duplicate the problems that I'm having. The problems continue. My engine light came on while I was driving and stayed on. I was told to bring in my car. The dealership kept it from July-Sept 2025, replacing parts and then returned it to me. Two days later the engine light came back on and I had to return to the dealer again for service. After leaving a parking lot (Jun 2026), two blocks down the street the TAOS began to lose power, the engine light is flashing and the EPC code (engine control malfunction) light lit up. I called VW and they dispatched a tow. My TAOS was towed to Checkered Flag VW. My safety (and others) is at risk because the power loss just happens without warning. If a driver is not paying attention, they could run into the back of me or hit me on the side during a lane change due to the slow movement.

The contact owns a 2022 Volkswagen Taos. The contact stated that while driving approximately 25 MPH, the check engine and ECM warning lights illuminated, and the vehicle decelerated and would only operate in LIMP Mode. During the failure, the vehicle was shaking and vibrating abnormally, and it was difficult for the driver to control the steering. The vehicle was driven directly to the local dealer, who diagnosed the vehicle with a cylinder #3 misfire. The cause of the misfire was not determined. The manufacturer was not yet contacted. The failure mileage was 38,000.

My car has lagged two different times and would not accelerate causing me to get off the road and turn the car off. The two occurances were about 6-8 months apart from eachother. The engine recorded multiple misfires and the second time it happened I was able to get a video of it. The dealership said that I ran out of gas the first time, even though I had a quarter of a tank and said that it went into lower power mode. The second time it happened they didn't know what was wrong with it because they couldn't reproduce the problem. I have also had problems with the sudden collision light coming on even though there is nothing in front of me. At times the car breaks on its own if I'm using the cruise control, making sudden stops. I have told the dealership this problem as well, but they didn't know what to do because they couldn't reproduce the problem. The final problem I'm having is with the brakes. My car has about 33, 000 miles on it and I had it in for service early February for an oil change. When it was in they said I needed new tires, but said nothing about my rear brakes needing to be changed. I then took my car in to get new tires about a month later and the company said that my rear brakes were going to need to be replaced soon. After traveling just under 800 miles, my brakes started to grind and were showing that they needed to immediately be changed. My front brakes are like brand new brakes. Multiple mechanics have expressed that my brakes shouldn't have worn so quickly and that if anything it should be the front brakes, not the back. I recently called VW to ask if there was a problem with the brakes and they said no. However, after investigating more online, I found that it is a problem in other Taos vehicles.

While attempting to accelerate from a stop, my Taos began to shake, the check engine light began flashing, and the car felt as if it were going to stall. I pulled over, turned the car off, turned it back on, and the car was drivable. This occurred around 5,000 miles. The dealer confirmed multiple misfires and a high pressure oil leak. The parts were replaced. My taos has a terrible lag when accelerating. This is a constant problem. It barely moves then all of the sudden it will take off, causing the wheels to spin out and your head to hit the headrest. This is extremely dangerous and has almost caused multiple accidents for me. I took the vehicle in to service and they stated that the Emission pump valve was stuck open, causing it to drive badly. The pump was replaced at around 6,000 miles. The car continued to drive badly and at approx 7,000 miles, I was accelerating from a stop when the car began to shake again and would not accelerate. The check engine light began flashing and the start/stop error message appeared. I pulled over and turned off the car. I turned it back on and the engine light went off but the start/stop still did not work. I brought it to the dealer and they confirmed additional engine misfires. The dealer cleared the codes and advised me to use premium gas. The Taos is supposed to run on 87, not premium. There are multiple online forums for Taos Owners. A concerning amount of people have complained about these exact same issues with their vehicles and that VW's "fix" is to run premium gas. This vehicle seriously needs to be looked into, as it is posing a serious safety hazard to all involved.
