While driving on the freeway in the carpool lane, our Audi Q6 malfunctioned and lost power. There were numerous malfunction lights all at once. No other warning that the car was about to lose power. I was forced to coast across lanes avoiding traffic to the side of the road. Steering wheel was also violently shaking. The car has been out of service at the dealer for 58 days as of today. The manufacturer and dealer have both spent time analyzing the car and replaced the 12 volt battery and some control modules. Here is the text message I received from the service advisor at the dealer: "the following are the latest notes from the technician and techline audi :The control module for engine and suspension control is the module that has the static low voltage faults. Tech line thinks this control module staying awake is what's killing the 12 volt battery. …

I am experiencing repeated and unpredictable software failures in my vehicle that create serious safety concerns. While driving, the vehicle will intermittently trigger system faults that: Disable advanced safety features (including driver assistance systems) without warning Emit a frequent, high-pitched warning tone that is distracting and disruptive Occur mid-drive, forcing me to manage the vehicle without expected safety support At the same time, the vehicle exhibits broader system instability, including: Inability to charge or unexpected charging interruptions Failure of keyless entry and locking/unlocking functions, sometimes preventing me from entering the vehicle General electronic system unreliability across multiple vehicle functions These issues appear to stem from software instability and occur without a clear trigger. …

I am reporting a severe, life-threatening safety defect involving the central locking system, electronic door latches, and the Multi Media Interface (MMI) control system on my vehicle. While driving, the vehicle has experienced multiple simultaneous malfunctions that pose an immediate risk of injury or fatality to passengers and other motorists: 1. Unintended Door Opening While Driving: The passenger-side vehicle door has popped open completely on its own while the vehicle is in motion at normal driving speeds and was caught by the safety latch. 2. Unintended Fuel/Charge Door Opening: The exterior fuel/charge door unlatches and opens on its own while driving. 3. Passenger Entrapment: The central locking and latching system glitched to the point where a passenger was physically trapped inside and completely unable to exit the car. …

The vehicle exhibits multiple critical safety defects that pose a severe risk to my life and the lives of my children. Most notably, the steering system performs sudden, unintended maneuvers and the steering wheel moves with dangerous abruptness without driver input. Additionally, severe electrical failures frequently prevent the doors from opening or the vehicle from powering down, creating a high risk of entrapment. The seat belts frequently jam, making it impossible for passengers to release them in an emergency. Power windows operate spontaneously, and the car often refuses to lock or unlock. This vehicle has been out of service for a total of 63 days across 5 separate repair attempts. As of today, the vehicle has been at the dealership for 8 consecutive days with no updates or progress reports from the manufacturer. …

For more than three months, my Audi Q6 e-tron has been sitting at the dealership with an unresolved issue that they have failed to diagnose or repair. This prolonged inaction is unacceptable, and the near-total lack of communication or meaningful updates only compounds the problem. It is alarming that a premium vehicle equipped with advanced safety technology remains inoperable for such an extended period. This situation raises serious concerns about both the reliability of the vehicle and the dealership's ability to address critical issues. When safety systems are involved, delays of this magnitude are not just inconvenient-they are dangerous and erode customer trust. I demand that Audi take immediate action to provide a definitive resolution, whether through a successful repair or an appropriate remedy under the vehicle's warranty and applicable consumer protection laws. …

The central locking and keyless proximity systems suffered a catastrophic electronic malfunction. The vehicle completely auto-locked itself from the outside while the vehicle's smart keys, the driver's mobile phone, and a [redacted] child were all inside the cabin. The proximity sensors entirely failed to detect that the key was inside the vehicle, preventing any outside handle access or proximity unlocking. The occupant was temporarily trapped inside the vehicle. The manufacturer is currently holding the vehicle under an active repair order for related backordered high-voltage and electronic control modules from Germany, but has historically lacked a permanent fix for these door latch/locking software failures.
