2020 Audi S4 Complaints

  • Electrical System 04/19/2024

    My instrument cluster and its replacements have malfunctioned multiple times. The original instrument cluster/virtual cockpit failed to boot and had a black/blank screen on 4/19/2024 at 29,687 miles and was replaced on 5/15/2024 at 29,923 mi. That replacement one worked fine for a while and then did the same thing on 7/15/2024 at 33,655 miles and on 1/10/2025 at 42,532 miles. The instrument cluster was then replaced again on 2/10/2025 at 43,841 miles. That replacement unit took only a couple of days to act up again with the blank screen on startup on 2/13/2025 at 43,965 miles and once more on 8/1/2025 at 52,673 miles. I'm currently waiting to hear back from the dealer to get the instrument cluster replaced once again.

    The Audi MMI malfunctions and reboots randomly while driving. Possibly being a software issue. There is a TSB code that the dealer used to reference for me ( TSB 2078437/1), but I cannot find it on the NHTSA website. The reboot issue shuts off all functions associated with it, including, but not limited to: navigation, rearview camera, and parking sensor use. This poses a risk since it can be distracting to pull back your navigation while driving or having your rearview camera cutoff mid mid-use. The issue does not appear as a warning lamp or any type of notification, and there are multiple reports of similar issues on online forums that have not been addressed.

    The MMI reboots continuously throughout my drive - whether it is 1 minute or an hour. It does this without a Bluetooth connection or wired connection. There is no ability to use hands free calling, listen to the radio, use Apple car play, Bluetooth, navigation, back up camera, parking assistance… It is startling to have your camera black out on your as your backing up (may back up camera works for about 45 seconds before stopping) I have done a hard reset. This is a problem that I am reading over and over and over again on forums I live nearly 2 hours from a dealer who takes weeks to get into and looking at a huge bill Hoping there is a fix soon

  • Electrical System, unknown Or Other, back Over Prevention 07/01/2025

    I am submitting a formal complaint regarding a persistent and dangerous issue with the MMI (Multi Media Interface) system in my 2020 Audi S4. Since February 2025, the system has been spontaneously rebooting both while the vehicle is idling and in motion. When this occurs, the screen goes black and critical safety systems such as the rearview camera, parking sensors, and navigation become unavailable. The system requires driver interaction to restore functionality once it restarts, creating a major distraction. These reboots now occur every few minutes, severely affecting both usability and safe operation of the vehicle. Initially, this issue happened infrequently (about once every two weeks), but over time it has become constant. Based on extensive online reports from other owners—including threads such as this one on AudiWorld: [XXX] appears to be a widespread defect affecting other Audi A4/S4 vehicles of the same year. This malfunction compromises several driver assistance and sa...

    The main infotainment system is stuck restarting every 1-2 minutes. When the car is put into reverse, the rear back up camera will turn off while the vehicle is in motion and not resume.
