2023 Volkswagen Taos

​SUMMARY OF SAFETY HAZARD: I am reporting a catastrophic and unpredictable loss of motive power in a 2023 Volkswagen Taos (4Motion with DQ381 DSG Transmission). The vehicle presents a critical electronic sensor failure within the transmission mechatronics unit that causes the vehicle to enter an immediate "Limp Mode" without warning. This has resulted in several near-miss incidents where the vehicle became immobilized in active traffic and on high-speed roadways. ​TECHNICAL DATA OF FAILURE: Factory-level ODIS diagnostic logs (recorded Feb 3 and March 17, 2026) reveal that the transmission’s "Actual position clutch 1" reports a constant value of -0.69 bar. In an automotive hydraulic system engineered for positive pressure, a reading of -0.69 bar is a physical impossibility (a vacuum state). This indicates a total failure of the pressure sensor/TCU logic, leading to the unintentional disengagement of the primary drive clutch. ​DECEPTIVE REPORTING RISK: Authorized service centers have been documented falsifying the safety status of this vehicle. Despite possessing internal diagnostic logs showing the -0.69 bar vacuum failure, a dealership issued a final Service Order certifying "No issues found" and stating "Actual values match." This reporting practice is forcing a vehicle with a known, documented powertrain failure back onto public roads, creating a severe life-safety risk for occupants and other motorists. The vehicle is currently grounded to prevent a collision.

On 12/20/25, the "lane assist not available" and the "EPC" warning indicators lit up. I was in the car with my 11 year old, we pulled over and looked in the manual to understand EPC, and the manual said it "is possible to continue driving," so we continued. As we entered the freeway the car went into limp mode and would not accelerate. I put the gas pedal to the floor, put on my hazard lights, and got off at the next exit, but we did were not able to drive > 40 mph on a crowded, rainy freeway with big-rigs ahead, behind, and to the left of us. We got off at the next exit, drove to a parking lot and let the car rest for 10-15 minutes. When we turned it back on, the "Exhaust System Malfunction" light and "Central Warning Light" indicators were on. The lane assist not available indicator had lit up a day prior, as well. My safety and the safety of my child were at risk on the freeway. I called the dealership from which I had purchased the car 2 years earlier and which has ~11,280 miles. I was told by their service department to drive the car home, but not to drive it after that. However, they also told me to drive the car from my home to their shop (10 miles), but to avoid the freeway, in order to have it serviced. This suggestion also put me at risk, as it would have been unsafe to drive the car between my home and their shop. I did call back to say that I didn't feel safe driving it, at which point they looked up my car and saw that it is under warranty, which includes roadside assistance coverage. The car will be towed to their shop on the morning of 12/22/25.

While driving Dec 10, 2024 my VW Taos failed to accelerate after slowing at an intersection. If this happens when I’m turning, on coming traffic has to slow down unexpectedly. The EPC light and check engine light came on. Car would not go above 15-20 mph. Called dealer and cautiously drove car to dealer. The mechanic said a popped fuse was reason the lights came on and car wouldn’t accelerate. They replaced 10A fuse and said codes/lights corrected. Now on 12/23/24 same exact issue has occurred. This is a huge safety concern. Taos 2022 models had a safety recall for a fuel delivery module that was causing that exact same issues and EPC and check engine light to come on. I am waiting for the dealer to call me back now to discuss how serious this really is and to get them to acknowledge they didn’t truly diagnose the vehicle the first time (given the 2022 Taos safety recall). Please investigate, I believe the 2023 models have the exact same problem. Not being able to accelerate is dangerous in multiple scenarios.

Vehicle will take off like a rocket when accelerating from a stop. I had to restart the vehicle because it had no acceleration before issue started. Took to the dealer was told that this is normal. I was then advised to put the vehicle in sport mode and it should stop. Vehicle has only 3300 miles on it and this is a new issue that just started. Took it to a local shop and it showed a p2422 so we took it to the dealer and that’s when they stated no codes found and no issues found. We have multiple videos of the rocket take off.

The component that appears to have malfunctioned is the vehicle's turbocharger or acceleration system. This issue is reproducible upon request for inspection. The malfunction poses a significant safety risk as it creates a delay in the vehicle's response when turning, leaving the vehicle momentarily stranded in the middle of the opposite lane. This puts the driver and other road users at risk of collision. The problem has been confirmed by my dealership. They attributed it to turbo lag and advised against using Sam's Club gas. Despite following their advice, the issue has persisted. The vehicle has yet to inspected by my dealership. There have been no inspections by the manufacturer, police, or insurance representatives as of now. There have been no warning lamps, messages, or other symptoms prior to the failure. The acceleration lag was initially subtle but has progressively become more severe over time. Whenever I attempt to make a normal right or left turn, my car hesitates for approximately three seconds before abruptly accelerating into the intended lane. This delay leaves me temporarily stuck in the middle of the opposite lane, creating a hazardous situation. The dealership diagnosed it as turbo lag and recommended against using Sam's Club gas, but the issue persists and has worsened. Now, the car exhibits significant acceleration lag after stopping for more than three seconds, followed by a sudden surge of speed. This behavior is particularly dangerous at intersections and during turns.

I purchased the new 2023 TAOS Volkswagen. I am experiencing sudden burst of acceleration when I’m gently accelerating. I have had several near misses of having an accident. I have read several other reports of the same problem on online forums. What is Volkswagen going to do about this? I just paid $35,000 for this new car and I’m afraid I’m gonna have an accident the way it suddenly accelerates. Please contact me so I know if there’s anything I can do to resolve this problem. This car is my only transportation and it scares me to drive it. This should not be happening.

Pulling into a parking spot, vehicle had a sudden burst of acceleration, as it was still on the road, resulting in an accident. Vehicle drove over a parking curb, hitting a small tree and a sign. Vehicle felt like there was a lag in response timing of the throttle to acceleration response. No one was injured, including myself the driver. Vehicle at this moment is at the VW dealership getting repaired. Insurance was notified at time of accident. No warning lights occurred at time of accident.
