2025 Audi SQ6 E-TRON

Driving home on the highway this evening, my vehicle sounded a couple of alarms and said driver assistance systems (which I wasn’t using) stopped working, and my accelerator completely stopped working. I was forced to unsafely cut across several lanes of traffic to an upcoming exit and coast until I could pull-off into a zone for “authorized vehicles only.” After coming to a complete stop, I placed the car in Park, and then shifted back into Drive, and the acceleration functionality returned. I looked for any recall notices, and I noticed that prior model years of this vehicle for 2022-2024 have had recall notices for this exact issue, and based on my experience this evening, I suspect my 2025 model year might have the same issue.

Yes. The vehicle has experienced multiple critical system failures, most notably involving a defective SX6 module, which is a central control unit responsible for coordinating key electronic, safety, and communication systems. Its failure has led to widespread issues, including persistent warning messages, driver assistance malfunctions, MMI system instability, and ultimately a complete high-voltage system shutdown while driving. The repair is extensive, requiring full module replacement, software programming, and system recalibration across interconnected systems. The vehicle has remained inoperable due to significant delays in obtaining this part. This defect appears to be widespread among this vehicle’s make and model, as evidenced by numerous owner reports and forum discussions describing similar SX6 module failures with limited long-term resolution. The vehicle and all affected components are available for inspection upon request. The safety risk has been severe. The lane keep and lane centering system has shut off abruptly at highway speeds without warning, causing the vehicle to drift or swerve out of its lane and creating a high risk of collision. More critically, the vehicle suffered a complete high-voltage system failure while driving on public roads, resulting in a sudden and total loss of power without warning. This creates an extremely dangerous situation, as the vehicle cannot maintain speed or safely respond to surrounding traffic, significantly increasing the risk of an accident. Yes. The issues have been reproduced and confirmed by an authorized dealership, which also diagnosed a failed module requiring replacement. No. The vehicle and its components have not been inspected by the manufacturer, police, insurance representatives, or other third parties. Yes. Numerous warning lights, system notifications, and other symptoms began appearing within a few weeks after purchase. The vehicle was purchased in September 2025.

UPDATE TO EXISTING COMPLAINT #11717767: On 2/24/2026, the Audi dealer performed a diagnosis and confirmed in writing on the attached official Repair Order that the vehicle is designed to intentionally blank out the instrument cluster and speedometer for 30-60 seconds during an MMI reset, which they acknowledge is a safety hazard while driving. Please merge this dealer admission PDF attachment with my original complaint.

The contact owns a 2025 Audi SQ6 E-Tron. The contact stated that while driving at an undisclosed speed, the instrument panel became inoperable. The contact stated that after the vehicle performed a system reboot, the instrument panel remained inoperable, and the display appeared blank. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 3,050.

Audi mmi safety systems regularly go into failure/ error mode (see photos ) - screen says car can still be driven on screen but all warnings flash continuously and safety systems do not operate until car turned off again, often errors and failure of safety systems to operate continue on next start up -often 1-10x times a day, then no issues for a couple days. Reported to Audi w description and photos, no fix offered accept “bring in for service”. Seems to be a common issue w/ other owners from web search Have not brought in for service.
