What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2020 Audi S5, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
MMI - Multi Media Interface constantly reboots about every 90 seconds. This is a safety issue since if I am backing up and the MMI reboots I lose the backup camera and when the MMI reboots I also lose collision/parking/proximity sensors. This issue started happening with my Audi on 7/26/25 and can be reproduced every time the ignition is on or car is running. From doing a quick search on the internet this is a very common problem that just started happening within the last few months with a number of 2020 model Audi's.
THE RADIO (MMI SYSTEM) IS REBOOTING WHILE DRIVING EVERY 5-10 MIN. DEALERSHIP CAN'T FIX AND IS AFFECTING SAFETY SYTEMS LIKE FRONT AND REAR CAMERAS/SENSORS.
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
