2023 Volkswagen Taos: check engine light

Filed Sep 23, 2026 · Electrical · FL

I bought the vehicle 3 years ago and currently it is at the shop to have the engine wiring harnes repaired. A few weeks ago, my dashboard started glitching. On 9/19/2026, my vehicle would not start. The check engine, EPC, low battery voltage, and traction light came on. I had to call someone to give me a jump so that my vehicle would start. It was impossible for the vehicle to keep a charge and it kept acting up in traffic. The dealership now wants to charge me about $650 for a new battery. I believe that the faulty engine wiring harness caused the battery to die prematurely and I should not have to pay for it.

I went to the Fiesta Albqueurque VW June 2025 multiple times resulting in close to 2 weeks without a car. Found a oil leak and head gasket - bolt jam replaced. In XXX, car shook, took it to first Fiesta ABQ, who identified a low battery charge. However, the car continued to shake end of XXX and we then, took this to Rudolph volkswagon, [XXX], that blamed it on bad fuel (invoice attached). Check engine sign turned off for a day, and came back on on our major trip up north from [XXX] to [XXX]. This Dealership told us that we would be safe on the road from [XXX] to [XXX]. Yes, we made it but by sheer luck. third Attempt, took this car to [XXX], VW and they were able to change: CHANGED THE ENGINE OIL AND OIL FILTER AND REFILLED THE ENGINE WITH 4.2 QUARTS OF 0W20 SYNTHETIC OIL WITH A SPIN ON OIL FILTER AND REPLACED THE DRAIN PLUG AND DRAIN PLUG CRUSH WASHER. RESET THE SERVICE INTERVAL DISPLAY. CHECKED AND TOPPED OFF ALL FLUIDS LEVELS. REPLACED THE BRAKE FLUID, BLED AND TOPPED OFF THE SYSTEM. MULTI-POINT INSPECTION COMPLETED NO RECOMMENDATIONS AT THIS TIME PLEASE SEE THE ATTACHED MULTIPOINT INSPECTION A VIDEO MULTIPOINT INSPECTION WAS PROVIDED. RESET THE MAINTENANCE INDICATOR AND APPLIED A MAINTENANCE REMINDER STICKER ON THE VEHICLE Hose was finally replaced. Out of pocket costs app $400. Since there were numerous efforts I will list the final work done on the car however, I have all invoices needed since June 2025. I have too many invoices to upload. Your upload cannot handle size Also note all dealerships notified. No one takes accountability. Ref: XXX 2 Lemon law first hired: 1st one wasted my time; 2nd one stated VW did not take accountability and refused to deal with me.

I purchased a 2023 VW Taos SE about a year ago (May 2025) as CPO less than 7k miles. It is still under the warranty; however, I already had to bring this Taos to the VW dealership for 3x. First was A/C was not cool enough. They found a leak. In June 2026, I had to bring due to the engine light being on. They found out EVAP fuel leak detection pump being faulty. And less than 1 month later (July 2026), once again the engine light came on. This time apparently EVAP canister is the problem and needs to be replaced . My Taos is currently at the dealership.  I am reporting this, in case other Taos owners have similar experiences. Thank you.

While I was driving down the road going 40 mph I heard and felt the engine stop. My dashboard display and stereo cut off, and the check engine light, check oil light, check battery light, and tire pressure alert light came on. I could not accelerate my car or move it forward at all, I could not see the speedometer due to the dashboard display going out. I pulled over and put the vehicle in park before turning it off. I waited a minute or two and turned it back on with no issue, it proceeded to drive with no further problems. I took it in to the dealership where I purchased the car and they told me they performed all the checks possible and found no issue with the vehicle. They were unable to reproduce the issue when they drove the car. As of now this has happened once in this vehicle.

The vehicle begins to feel like it is skipping while driving. The EPC light comes on, the dashboard beeps and indicates lane assist is unavailable, check engine sign illuminates. The vehicle will drive for a short time but then jerks and just stops. This has happened at least 3 times. Dealer has already replaced the fuel pump, electrical wiring and some switch that wasn't readying properly. After the fuel pump was replaced, the tank was filled, continue to track down miles and gallons. When the vehicle got to 135 travel miles left and one notch above the gas tank, it jerked and stopped immediately at an unsafe spot on the road. The sensor was not properly reading the gas and the tank was empty! This last incident was the same evening after an inspection and 60K service. This vehicle is unsafe and VW should be making this right. Warranty has expired and now they want to charge me for the same issue. This has been going on for months and I believe the vehicle is unsafe and is putting me in danger of having or creating a bad accident.

The contact owns a 2023 Volkswagen Taos. The contact stated that while operating the vehicle, the check engine warning light illuminated. The vehicle was taken to the local dealer, who diagnosed that there was coolant intrusion into the head gasket. The head gasket was replaced, and the vehicle was repaired. Later, while driving 55 MPH, the message "Transmission Failure" was displayed and the transmission shifted to D2, causing the vehicle to decelerate to 25 MPH. The vehicle was parked, and after restarting the vehicle, the vehicle operated normally. The vehicle was later taken to the local dealer, who diagnosed that the Medtronic transmission had failed and needed to be replaced; however, parts were on back order. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 10,185.

1)- Brake pads were worn out very fast twice when I first bought the vehicle. Eventually, the dealership had to replace them with after market brake pads. 2)- Check engine light keeps turning on and on - code P2421 EVAP canister stuck open despite all the expensive repairs at the dealership.

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.
