What owners say
The Alternator had failed along with the battery and shut off the car, rendering it useless on the road. The vehicle is still under the New Car Warranty. It was a hazard as it could not be put into neutral and was stuck in park. The dealer had confirmed it was a manufacturer-wide problem with waits of up to 3-6 months for the part. The tow truck had difficulty towing it up as the car was not able to roll. Before the car shut off immediately it had given the warning "Electrical System: Malfunction! Please Contact Service, as well as Auto Start Stop System: Malfunction!".
Electrical System Malfunction w/yellow battery icon...stop/start system unavailable. Vehicle deemed unsafe to drive. Towed to dealership, part on worldwide B/O...estimate several month wait for starter/alternator
I received a yellow alert that the auto start/stop was malfunctioning. I continued to drive 8 miles until another message was displayed on the instrument panel that stated: "electrical system malfunction" with a yellow battery icon. A few seconds later the same "electrical system malfunction" with a red battery icon appeared. I then had numerous failure warnings on other car systems such as driver assistance sensors and steering; the display screens started to flash on and off. I slowly guided the car to a complete stop and called Audi Roadside Assistance for towing to my local Audi dealer.
This issue happens when the car is stopped and the auto stop/start feature has stopped the engine. Most commonly at a stop light at a major city intersection, where the lights are longer. When the system attempts to restart the engine, it rough idles and then the drive system shuts down the engine, causing you too lose all power. This leaves you stranded, and risks causing someone to rear-end your vehicle if the light changes. Putting the car in park, turning off the ignition, and then turning the ignition back on resumes engine function. This has happened multiple times. So far the service center has been unable to identify the root cause.
