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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2025 Audi SQ6 E-tron verdict →
