NHTSA Complaint #11689867 — 2022 VOLKSWAGEN TIGUAN

Subject: Ongoing Mechanical and Electrical Issues – 2022 VW Tiguan I’m experiencing ongoing issues with my 2022 Volkswagen Tiguan, purchased new and maintained under single ownership. Primary Issue: The vehicle shuts off unexpectedly under various driving conditions—while accelerating on the highway, from a stop at traffic lights, and especially when going uphill or over high bridges. The issue initially occurred once or twice a year around 45,000 miles but has become more frequent. As of 70,000 miles, it now happens on a weekly basis. When this happens, the only way to temporarily resolve the issue is to turn off the vehicle completely and wait approximately 5 minutes before restarting. Recent Maintenance Completed: New car battery (3 battery since purchase of car) New spark plugs (Replaced in June 2025) Regular oil changes (every 3000 miles) New engine air filter and cabin air filter (yearly) Additional Symptoms: The rear-view camera frequently times out or fails to display when reversing. The dealership has not been able to confirm the cause but has mentioned a potential error code P30DE00, suggesting alternator replacement. However, a second opinion found no active error codes, leaving the root cause unclear. I'm seeking a definitive diagnosis and a resolution plan, as the issue has become a safety concern.
