2021 Volkswagen Passat problems

Filed Oct 28, 2026 · Electrical, Engine · VA

Since purchase in XXX, the vehicle has intermittently illuminated the EPC warning light at startup, at which point the engine will not accelerate (reduced power/limp mode). Cycling the ignition usually clears it. Beginning in XXX, a second symptom appeared: while stopped at idle (traffic lights, stop signs), the battery warning light illuminates and the engine stalls, requiring a restart in traffic. This has occurred approximately 8 times in XXX, most recently on Saturday, XXX when it happened twice. Wet or rainy conditions appear to make it worse. Stalling in traffic results in loss of power steering and brake assist and is a safety hazard. The vehicle has been to Volkswagen dealers six times for this complaint with no lasting repair: a wiring harness repair at Freehold VW (XXX); a boost pressure sensor diagnosis (XXX); an overlay harness, ECM-related repairs, and ECM software update under emissions recall 23EO (XXX); boost pressure sensor replacement (XXX); airflow meter replacement and harness repair (XXX); and re-pinning of loose connections at the ECM connector for the G31 boost pressure sensor (XXX), all at World VW in [XXX]. Fault code P0236 (turbocharger boost sensor circuit) has been recorded on every visit; P2261 was also recorded. The check engine light, EPC light, and stalling have all returned since the XXX repair. Current mileage is approximately 27,800. Repair orders are available on request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am requesting that Volkswagen open a formal case regarding a fire involving my 2021 Volkswagen Passat. On May 6, 2026, at approximately 9:30 PM, after driving about seven miles, I came to a complete stop and the vehicle began smoking before catching fire. The vehicle has been declared a total loss and is currently being stored at a salvage yard pending investigation. I am requesting that Volkswagen investigate the cause of the fire and advise whether an inspection of the vehicle will be conducted.

I was parking my car and then I heard a loud crack. Then I noticed my car's airbag malfunction warning notice came up on the dashboard along with other failures. I can see on the edges of the horn panel on the left that its slightly detached, so it seem the airbag has somewhat inflated. I haven't taken it to the dealer yet, but will later after work. I didn't notice any issues prior to this happening

Driving home from work around 1:00 am at night with street lights and no other cars in the vicinity the auto brake engaged, causing an abrupt stop. Once the auto brake ceased I was able to complete my trip. There was a light coating of water in a spot on the road but nothing else and no reason for this to occur.

There is a headlight chrome accent piece right above the left headlight that one day just blew off the vehicle when driving down the highway. Oddly enough, I live in a small town of Mason City, IA and I saw another VW Passat (same year) missing the same exact piece so I know this is a vehicle defect. You also can not just replace this one part, it costs over $1,000 to replace the full headlight assemble. I hope others report this defect as this is very dangerous when you have chrome pieces flying off your vehicle when it is not even windy and the vehicle has never had any other damage.

The forward collision was not working on my car when someone pulled down in front of me and I hit the wall so I wouldn’t hit them.
