2023 Volkswagen Taos electrical system problems

“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.”

“The infotainment touch screen on my 2023 Volkswagen Taos has completely blacked out and failed, leaving my backup camera entirely inoperable. This has created a severe blind-spot hazard where I cannot safely reverse. On top of this failure, the vehicle has a chronic history of being in and out of the dealership service department for unresolved fuel system problems, specifically regarding the fuel injectors and fuel lines under warranty. The dealership has repeatedly failed to permanently fix this fuel defect. Now, the car actively loses engine acceleration and drops into a dangerous slow crawl ('limp mode') at busy intersections when the air conditioning is running, forcing me to turn off the climate control just to move safely. Combined, these recurring powertrain and electrical defects create an immediate, severe safety hazard for myself and my young children while driving.”

“Marietta Volkswagen diagnosed a failed 5F module; the center display screen is completely inoperative; the rearview/backup-camera image therefore does not display when the vehicle is placed in reverse; VW says the module is on national backorder with no ETA; and the vehicle is being used by a [XXX] driver. Volkswagen Customer Care has already been contacted but could not help and that the repair is covered under warranty but cannot currently be completed so the vehicle remains unrepaired and is being operated without a rear view camera display .”

“In two separate instances the Autonomous Emergency Brake system was activated. Luckily there i didn't cause an accident. There was no one in front of me either times. Thats the worst of all the issues the vehicle has.”

“​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…”
