NHTSA Complaint #11673229 — 2020 AUDI A4

The MMI (Multi Media Interface) system is the component that failed. It began repeatedly rebooting, making critical features like Apple CarPlay, navigation, audio controls, and the rear-view camera inoperable. The failure became progressively worse after two separate repair attempts, including a software update. The 5F module, which governs infotainment, has been identified by the dealership as the part requiring replacement. Yes, the vehicle and failed component are available for inspection upon request. The malfunction disables the rear-view camera, which is a critical safety feature especially when parking or reversing in tight spaces. It also prevents access to navigation and voice-activated phone controls, which can increase distraction if drivers attempt to manually use a mobile device as a workaround while driving. The constant rebooting also creates visual and audible distractions in the cabin. Yes, the problem has been confirmed by an authorized Audi dealership (Audi of Smithtown). After the initial repair failed to resolve the issue, the dealership attempted the repair a second time. Following further analysis, they recommended a $5,200 repair involving replacement of the 5F module, which supports that they confirmed the problem exists and persists. The issue has been inspected and diagnosed by an authorized Audi dealership (Audi of Smithtown), but there is no mention of inspection by Audi of America, police, or insurance representatives at this time. There were no warning lamps or dashboard messages, but the primary symptom was the MMI system randomly rebooting. Initially, the reboots were occasional, but over time became constant to the point where the system was entirely unusable. This issue was present before the June 5, 2025 service visit and worsened significantly after the second repair attempt on June 21, 2025.
