ELECTRICAL SYSTEM
Owners report frequent issues with the 2020 Audi A4's MMI (infotainment) system, which commonly reboots every few minutes during operation. Typical symptoms include the screen going blank, loss of navigation and backup camera functionality, and disruption of audio and vehicle settings. These issues often occur both while driving and parked, with some reports suggesting the problem worsens over time. The malfunctioning MMI system poses safety risks by distracting drivers and disabling critical features like collision avoidance and rearview cameras. Complaints frequently mention that the problem persists despite attempts at software updates and dealer interventions, which are often costly and inconclusive.
Owner complaints34
UNKNOWN OR OTHER
Owners report that the 2020 Audi A4's MMI (Multimedia Interface) system frequently reboots unexpectedly while driving, causing the display to go dark and disabling critical features such as the backup camera, parking assistance, and collision avoidance systems. Complaints frequently mention that these reboots occur every few minutes, with some indicating the issue has worsened over time. This problem is noted to be particularly distracting, especially when using navigation or Bluetooth functions, and poses a safety risk by disabling the rearview camera during reversing maneuvers. The issue is reported across various mileage ranges, with several owners indicating it has persisted for months without resolution. This pattern of complaints may be relevant for potential buyers considering the vehicle's infotainment reliability and associated safety implications.
