Electrical System problem #1

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).

Electrical System problem #2

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.

Electrical System problem #3

Known issue in previous vw models. Broken clock spring in steering wheel from normal <100k miles no connection for all steering wheel electronics (airbags, radio controls, etc).

Electrical System problem #4

My car is currently hacked! I've brought it to 2 different dealerships and they just blow me off. If my phone is on while in my car, it at some point will just not go, no matter how hard u press the gas. I've had my seats and mirrors move while driving. It downshifts superhard. But if someone else is in the vehicle, nothing happens. I've showed videos that the service ppl can't explain whatsoever. Also people seem to shine bright lights at my car for long periods of time and after that, my rpms go so high and stay that way even while braking. Also people seem to love to get on a riding lawn mower and just let it sit by my car running and then again my rpms go crazy. Someone please help me my next step is a lawyer and a lawsuit. There are too many incidents to record. And this all started a year ago when at a light on a highway waiting to make a left turn, when the light turned green for me to go, it died in the middle of the highway making a left turn. So I was dead in front of oncoming traffic and after 2 weeks of having my car they replaced a "throttle body" and I've been living in hell ever since. I don't even believe they replaced it, all they did was fuck my car up and I can't be exact but I believe at the time it had under 40,000 miles.
