NHTSA Complaint #11690266 — 2022 VOLKSWAGEN TAOS

I am reporting serious electrical/CPU defects and dealership workmanship issues with my 2022 Volkswagen Taos. Since purchase, the vehicle has shown repeated electronic malfunctions: dash blackouts, HVAC/remote start errors, infotainment resets, and a cooling fan that ran 24+ hours after shutoff. Warning alerts are delayed or absent (no warning before head gasket failure at 42k miles; oil-level alert appeared 8 weeks after a dealer oil change; turbo underboost fault only appeared 9 months after a missing O-ring). Independent scans (AutoZone) have shown generic fault codes (ABS communication error), while Volkswagen dealerships repeatedly reported “no faults found.” Service staff told me they only read “VW codes,” ignoring generic ones that point to safety problems. Major events tied to these failures: Nov 2024: Head gasket failure at 42k miles, no warnings triggered. Aug 2025: Turbo charge pipe disconnected at highway speeds, car went into limp mode. Independent shop documented it “must have come loose or was not properly installed.” Sep 2025: EPC again; dealer found missing O-ring on intake pipe, likely from Nov 2024 repair. These failures have repeatedly stranded me in limp mode with my child in the car. The CPU’s failure to log and alert is a systemic defect. A similar delay with steering or braking could be deadly. I have raised concerns with Fox Valley Volkswagen since 2022 and sent certified letters in Sept 2025. They denied responsibility, calling each failure “unrelated.” Volkswagen of America also pushed me back to the dealer. This is not a one-off repair issue. It is a systemic CPU/electrical defect suppressing warnings until after failure, compounded by sloppy workmanship. My car is unsafe to drive. I request investigation into VW’s diagnostic practices, CPU/sensor monitoring delays, and dealer handling of safety-critical repairs. I have Service reports but I ran out of room and they couldn't be attached with the rest of the documents below.
