While driving my 2020 Audi S6, the vehicle suddenly lost power and completely shut off in the middle of the road without warning. There were no warning lights or messages beforehand. I was unable to accelerate or steer out of the way, which created a major crash risk for myself and other drivers. I had to have the vehicle towed to Audi of Riverside for diagnosis and repair. The dealership confirmed the issue was related to Recall 22V861 (Gateway Control Module). I was never notified by Audi of this open safety recall prior to the incident. The problem was immediately confirmed by the dealership, and the vehicle has been in the shop since September 2024 — now over eight months — with no ETA on parts from Audi and no resolution. During this time, Audi has not provided a loaner vehicle or rental support. I’ve continued to pay my monthly car note for a car I cannot use and have spent hundreds of dollars per month on Uber and alternate transportation to get to work. Audi issued a $3,000 goodwill check, but that does not begin to cover my actual out-of-pocket costs. I also previously requested a vehicle buyback, which was denied. This is a serious safety defect that caused a dangerous on-road failure, and the manufacturer has failed to provide a timely or adequate remedy. The issue has been confirmed by the dealership, and the vehicle is still not repaired or returned to me. I’m requesting immediate investigation and enforcement regarding this unresolved recall and the unreasonable delay in resolution.

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 2020 Audi S6 verdict →
