Electrical system

5 reports1 crash
“The contact owns a 2026 Audi A6. The contact stated that while driving in stop-and-go traffic, a second vehicle reversed and struck the front end of the contact's vehicle. During the crash, the driver's side front air bag failed to deploy. The contact sustained a neck injury that required medical treatment. A police report was taken at the scene. Following the crash, several safety-related failures occurred while operating the vehicle, including an illuminated air bag warning light, an "SOS system not available" warning message, a malfunctioning seat belt restraint that failed to properly secure the driver, and a trunk lid that failed to latch properly. The vehicle was taken to the dealer, who was unable to determine the cause of the failures. The manufacturer was notified of the failures. The failure mileage was 21,002.”

Forward collision avoidance

3 reports
“This report is on a new vehicle. The incident occurred within one week of purchase. While driving on a freeway at constant speed, with the closest vehicle in front of me approximately 25 yards away and with no warning, the car slammed on the brakes in an emergency fashion and aggressively tightened the seat belt shoulder harness. This was followed by a notice "emergency call cancelled". It is clear that the Audi pre sense malfunctioned and caused the system to think a rear end collision was imminent, when clearly it was not. The internet is littered with complaints about this. Fortunately, this did not result in an accident, but I would classify it as a near miss safety incident since if someone had been close behind me it likely would have resulted in a rear end collision. I have reported this to the Audi dealer that I purchased it from. Given that I haven't had a car accident in forty years, I consider this system more of a safety hazard than a help.”

Lane departure

2 reports
“We are reporting serious safety-related faults involving my leased 2026 Audi A6, VIN [XXX] , and a same-model 2026 Audi A6 loaner provided by Audi Central Houston. Core safety issues: 1. My vehicle previously displayed a Park/rollaway warning indicating Park could not be engaged. 2. My vehicle has had repeated starting-system faults, including: “Engine start system: malfunction! Please contact Service.” 3. Our vehicle has been the subject of multiple repair visits at Audi Central Houston and is currently at the dealer, available for inspection. 4. After the third repair order, Audi Central Houston represented the vehicle was ready for pickup. Before we accepted return, the same starting-system malfunction reportedly recurred during Audi’s own test-drive/verification process. Audi added that April 30 recurrence to the still-open third repair order. 5. While our A6 remained at the dealer, Audi Central Houston provided a same-model 2026 Audi A6 loaner. That loaner displayed: “P not possible. Risk of rolling away! Please contact Service.” A photo is available. 6. Because the loaner warning stated Park was not possible and there was a risk of rolling away, we did…”
