Approximately four months ago, I made a purchase of a 2020 A7 with 27,000 miles on it. The vehicle's maintenance record indicated that it was in good condition. However, I encountered an electrical malfunction while driving back from work. Initially, a yellow alert appeared, followed by a red alert indicating safety concerns and advising me to stop the car. Unfortunately, the car completely lost power and became inoperable. I typically drive only 15 miles per day. After conducting some research, I suspect that the issue may be related to either the alternator or the 48-volt hybrid battery. I had the car towed to a nearby Audi service centre, but it has been a week and they have not taken any action. Despite my repeated calls, they have not even performed a diagnostic to identify the exact problem. I am wondering what steps I can take to escalate the situation or communicate my concerns to Audi of America (AOA).
It is expected that the guarantee covers the repair of all these problems. Please provide guidance. Thank you.
