2025 Audi Q6 E-TRON

Sudden complete loss of propulsion while driving, with no opportunity to safely leave the travel lane; failure repeated again seven miles later after vehicle restart. Once propulsion is lost the driver has 1 to 2 seconds before multiple loud banging noises and the vehicle shuddering to an immediate stop without the driver using the brake pedal. The warning on the dash was "High Voltage Electrical System Fault" all in red.

I am reporting an unresolved safety defect involving my Audi Q6 e-tron. Before August 5, 2026, the vehicle had repeated intermittent electronic/system malfunctions, including safety warnings, systems becoming unavailable, loss of audio, Apple CarPlay failures, “technical error” messages, and the interface freezing on loading screens even after restarting. I have photos and videos documenting many of these issues. The vehicle was taken to an Audi dealer on August 5 and returned August 12 after service that included a KD2 update. On August 17, while making a left turn through an intersection, the driver’s seat suddenly moved substantially/full rearward as the steering wheel/power steering column moved all the way upward. This changed my driving position while the vehicle was moving. I could no longer properly reach the accelerator and had difficulty maintaining control, creating an immediate risk of losing control or collision. I could not determine whether the vehicle also temporarily failed to respond to accelerator input or whether my inability to reach it was caused entirely by the seat movement. There were no warning lamps, messages, chimes, or other symptoms immediately before or after the event. The vehicle was returned to the Audi dealer and escalated to Audi corporate. A TAC case was opened and a regional case manager assigned. On August 26, the dealer advised there were no fault codes identifying the cause. The dealer did not state that the event had been reproduced and did not identify a failed component. The MMI was reset/updated again, but no definitive cause or repair was identified. The precise failed component is unknown, but the event involved the power driver’s seat and power steering-column positioning systems. The vehicle is available for inspection upon request.

While driving my Audi Q6 e-tron on the highway, the vehicle experienced a sudden and complete loss of propulsion and nearly all vehicle electrical/display functions. The instrument cluster and dashboard went completely black, and the vehicle would no longer respond to accelerator input. I was able to get the vehicle to the side of the highway. After the failure, the vehicle could not be restarted or driven. The dashboard and vehicle controls remained inoperative, and I was unable to electronically lock the vehicle. The primary functions that continued to operate were the hazard warning lights and the SOS emergency-call button. An unusual additional symptom was that the steering wheel continued to vibrate intermittently/continuously for hours after the vehicle had become inoperative, indicating that at least some electrical systems remained powered despite the apparent shutdown of the vehicle. Because the vehicle lost propulsion and its primary displays and controls while traveling on a highway, I consider this a serious safety issue. There was no indication that the high-voltage traction battery was depleted. The vehicle was towed to an authorized Audi dealership. The dealership has not yet identified the cause of the failure and has escalated the diagnosis to a specialized Audi technician. I am submitting this complaint because a sudden and unexplained loss of propulsion, instrument displays, and vehicle control systems while driving could create a significant risk of a collision, particularly if it occurs at highway speed or in a location where the driver cannot safely move the vehicle out of traffic.

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. Leaving a customer without answers for months while a safety-related issue persists is unacceptable and must be addressed without further delay.

On XXX, I was driving my Audi Q6 e-tron southbound on [XXX] in the HOV lane at highway speed with my family inside. Without warning, the vehicle suffered a complete power failure, dropping instantly to zero acceleration.Because I had no propulsion, I was forced to coast the unpowered vehicle across three lanes of active traffic to reach the right shoulder. Trailing traffic approaching quickly from behind narrowly avoided rear-ending us, and the vehicle side-slipped multiple times during the coast. It is a miracle my family survived the maneuver.Once I managed to get the car stopped on the shoulder, the vehicle exhibited erratic and dangerous electronic behavior. The car remained running and flatly refused to shut off despite my attempts. Furthermore, for some completely unknown reason, the steering wheel would not stop moving and shaking back and forth (right and left) entirely on its own while the vehicle was stationary.The California Highway Patrol (CHP) arrived to secure the scene. I used the vehicle's emergency contact button to contact Audi. While waiting, I called Calabasas Audi, where the car was being towed, and spoke to an employee named Ark. Ark stated he had never heard of this happening (the car not shutting off and the steering wheel shaking). He instructed me to push the door lock/unlock button to see if it would reset the system, but this did nothing. The vehicle was completely disabled and unsafe to operate. This severe defect put my family's lives at risk, and I have zero trust in this vehicle. I request an immediate safety investigation.

On May 6, 2026, while operating the vehicle on a neighborhood street, the vehicle experienced a sudden, violent, and dangerous failure. After accelerating away from a stop sign, the vehicle was traveling at approximately 20-25 mph when, simultaneous with a warning message, it came to an immediate and abrupt stop. A number of error messages appeared in rapid succession on the vehicle’s MMI. Those messages referenced, among other things, drive battery errors, a major electrical system failure, and drivetrain issues. After the abrupt stop, the driver, attempted to restart the vehicle. Following one failed attempt, the vehicle restarted; however, after traveling approximately 30 feet, the vehicle again came to an abrupt, violent, and sudden stop. After several additional failed attempts to restart the vehicle, the driver allowed the vehicle to sit idle for approximately five minutes. The driver was then able to restart the vehicle and drive it, very cautiously and slowly, approximately two miles to a safe location. Once in a safe location, driver contacted the dealer who confirmed that the vehicle was unsafe to operate. The vehicle was towed to the dealership. On May 7, 2026, the dealer informed us that they had found “several different faults stored in the vehicle but those faults all basically contradict each other.” The dealer further informed us that they would need to contact Audi in Germany for guidance on how to proceed with diagnosis and repair. On May 22, 2026, the dealer informed us that "(w)e do need to drop the battery. There is a module in one of the battery cells that we are going to replace and also the module that controls the battery as well".
