NHTSA complaint #11717011

Owner complaint summary

I am reporting a safety defect involving (1) sudden loss of propulsion (“turtle mode”/limp mode) while accelerating/merging into traffic and (2) unintended steering movement while driver-assist/lane centering was active (vehicle jerked toward adjacent lane and off roadway). These events create an immediate crash risk. The vehicle has also had repeated charging-related overheating/charging stoppage events, which I believe may present a fire risk when charging in a residential garage. Repairs have been attempted multiple times by an authorized Porsche dealer, but defects persist. Warranty has now expired, and an independent scan shows ongoing network/data bus/12V monitoring faults consistent with continuing electrical/network instability. I am requesting NHTSA review for a potential safety defect investigation/recall.
