2023 Volkswagen Taos Electrical Problems

While driving in heavy traffic, your gas pedal suddenly stopped responding and wouldn't let you accelerate. About 10 seconds later, your brake pedal became stiff and also stopped working, leaving you unable to control the car. You had to put the car in Park and restart it to regain control of both pedals. The dealership couldn't find any trouble codes or warning lights, but you're concerned about driving the vehicle again. A technician will need to diagnose the electronic throttle control and brake system to determine why both pedals lost function simultaneously.

Your 2023 Volkswagen Taos has shut off completely while driving at least three times, with multiple warning lights appearing each time. Most seriously, during the third incident at 55 mph on the highway, the engine shut off and you lost power brake assist, making it extremely difficult to stop safely. The dealership has attempted repairs twice but the problem keeps returning. Fixing this will likely require the dealership to diagnose and repair the electrical and brake system components that are causing the engine to shut off unexpectedly.

Your car experiences engine hesitation and jerking while driving, triggering warning lights for engine problems, lane assist unavailability, and electronic stability control. The vehicle then suddenly stalls and stops completely—this has happened at least 3 times. The dealer has replaced the fuel pump, wiring, and a faulty switch, but the problem persists: your fuel gauge reads incorrectly, showing gas remaining when the tank is actually empty, causing dangerous stalling on the road. Fixing this will likely require proper fuel sensor diagnosis, gauge cluster testing, and possibly additional fuel system component replacement or electrical circuit repair.

Your 2023 Taos unexpectedly shuts off completely whenever you stop for more than about 60 seconds, such as at red lights. When this happens, you have to shift into Park, turn off the ignition, and restart the engine before you can drive again. The dealer has scanned the car twice but cannot find a cause or reproduce the problem. This is dangerous because it forces you to restart your car in traffic, increasing the risk of being rear-ended or getting into a crash.

Your engine light turned on shortly after you started driving, displaying a 'start/stop error' code. Your car is limited to a maximum speed of 30 mph and won't accelerate beyond that. The issue likely involves the engine's automatic start/stop system or a related electrical component that needs diagnosis and repair.

While driving at 40 mph, your engine suddenly shut off and your dashboard and stereo went dark. Multiple warning lights appeared (check engine, oil, battery, and tire pressure), and you lost the ability to accelerate or see your speedometer. After pulling over and restarting the vehicle a couple minutes later, it operated normally with no further problems. The dealership performed diagnostics but found nothing wrong and couldn't reproduce the issue.

The contact owns a 2023 Volkswagen Taos. The contact stated while driving 45 MPH, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The ETC (Electronic Throttle Control) warning light illuminated. In addition, the engine revved independently. The vehicle was taken to the dealer where it was diagnosed that the cam shaft timing had failed. The timing belt and cam magnet were replaced. The contact stated that on a separate occasion, while driving 45 MPH, the vehicle failed to accelerate as intended while depressing the accelerator pedal and the engine revved independently. The ETC warning light illuminated. The vehicle was taken back to the dealer and was diagnosed that the cam shaft sensor had failed. The vehicle was repaired. The contact stated that recently the vehicle failed to accelerate as intended while depressing the accelerator pedal. The vehicle was taken back to the dealer to be diagnosed and the contact was informed that the air hose had failed. The vehicle was repaired. The contact stated that several unknown warning lights were illuminated intermittently. The manufacturer was not made aware of the failure. The failure mileage was approximately 11,000.

Accelerating Transmission Shifting When accelerating from a full stop, using same force of pressure on foot to accelerate the vehicles behaves differently every time. Vehicle will rev and have a 1-3 second delay to move the wheels/tires, or have no delay. There is no common variable to know how the vehicle will accelerate from stop to stop. Have tried to narrow down anything unique to identify when this happens but it is sporadic and unknowing how the vehicle will behave. Specifically, have noted if the occurrences are unique to: Slope or incline, humid weather versus dry, fuel type (have always used same), cold temperatures versus warmer or cool, or any unique non-ordinary operating conditions. Safety risk- anytime vehicle is supposed to accelerate. Daily safety risks- We enter a roundabout and attempt to accelerate, and vehicle hesitates for 3 seconds causing us to not enter or risk hitting vehicle oncoming. Vehicle behind attempts ot accelerate as well usually resulting in. honking at us- daily. Left hand turn. Apply pressure to accelerator, and cannot make turn or get hit by oncoming vehicle. Parking lot. Accelerate over speedbump, vehicle lags/rev's, and then rapid acceleration causes vehicle to jolt almost hitting people/animals. Window will go up when switch is in position to lower and vice versa. Issue from day one. Our dog was in vehicle. Window down about 4 inches. At intersection. Went to accelerate which hesitated while holding switch to lower window, and window went up with our dogs nose still between car interior and exterior. Focus was on driving if we could make through intersection and could only imagine if we had a child with their hand out. The above is noted when vehicle has been in for service. Vehicle is currently at dealer and we will not accept vehicle until Volkswagen identifies issues. Known issues with this year and model AWD model.

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.

The vehicle has 8000 miles on it and was sold to me knowing it had a well known head gasket problem. The vehicle has acceleration and overheating problems when it runs out of coolant which is leaking. The problem has been confirmed by suburban Vw in Farmington hills Michigan and it has been in service there since [XXX]. I reported the problem 8 months after purchase but they were unable to take it in due to many different reasons including lack of spare parts, not enough staff and no rental cars. I have had to top the coolant up on 5 occasions and have had leaks and stains on my garage floor which I reported INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

EPC (engine light) light came on two separate times while car stopped accelerating and was shaking a lot with smells of chemicals from vents all at once. Inside electrical issues as well. Car bought new First incident was the first week and a few months later and a year later

Vehicle has Bluetooth and stopped working. Took it to the dealer they stated the j494car net module not functioning. This caused the sos system to not work the Bluetooth not to work and the app to track the vehicle not to work. They had to replace the module to get it to work.

Purchased a 2023 VW Taos SE on December 21st, 2022, with 11 miles on it. The first check engine light came on the end of January 2023 and it started having the acceleration lagging issue right before that. Dealer said it was a fuel issue and fixed it. Second check engine light was in March, dealer said to not top off the gas when pumping and fixed it. Third check engine light came on in April and VW Corporate's Service team got involved, claimed it was an emissions issue and fixed it. This entire time, the acceleration lagging issue continued sporadically. To the point you would have to floor the accelerator to get it to move, especially when changing lanes in traffic. Which a 2-3 second delay is dangerous! I had a car behind me honk, because the Taos was not accelerating. No matter what the dealer did to fix it, it did not work. Other issues include playlists not playing in Apple CarPlay, a rattle noise when accelerating, e-brake turning on by itself, air not blowing cold, dashboard and entertainment screens dimming for no reason and the smell of sulphur in the car. I followed Florida's Lemon Law and VW bought back and refunded me for the Taos as it is a bonafide lemon! This was my 6th VW and my last. The issues the Taos has reminds me of VW's timing chain tensioner lawsuit, which affected VW #5.

I purchased the 2023 Taos SE at the beginning of may. When accelerating on the highway, the ACC light and engine light came on and the car started rapidly decelerating. Lane assist, cruise control and ACC were not able to be used. I managed to pull to the side of the road, and was towed to a VW dealership in Rochester. The computer came back saying it was bad fuel. They drained the fuel, and charged us due to user error/using the wrong fuel. I have confirmation from the gas station this is incorrect. The next day, the same incident happened when accelerating on the highway. My hometown dealer also ran a report and it came back as bad fuel. They drained the fuel, but kept the car to test drive. I refused to take it back until a different solution was found. They finally were able to recreate the situation, and said there was an issue with a fuel injector module. I picked up my car yesterday, and did not even get home before the car powered down on the highway.

Check engine light came on not long after buying the vehicle, additional electrical issues began including window regulator failures and battery failure.

Within the first 24 hours of picking up this new car warnings for 3000rpm max appeared, engine overheating and potential damage to engine components appears and engine functioning was decreased, exhaust control malfaction message, and electronic engine control message with associated symbol for lane assist warning message. When the electronic engine control message with checklight appeared, acceleration was impaired and it was difficult to speed up on the road. There was the potential for fire and gasoline explosion and risk to drivers and passengers due to possible collision accidents. I have brought the car to the dealership and was turned away the first time due to being told it was low voltage. While drive home the EEC message, electronic engine control malfunction with warning light appeared again and I called and said I was going to drive back to the Volkswagen dealership and this time they took the car. This was a worrisome experience for me. .
