Was told that the rear differential was defective and needed to be replaced. After this rear differential was replaced, it still is not fixed. The problem was confirmed by the dealer. The vehicle has been inspected by the dealership and the manufacturer. No messages or warning lamps were activated. Symptoms of problems included reverberation of vehicle below the driver's seat, unable to keep the car in a straight line while driving. This only occurred when going a very low speeds.

Entered a roundabout at perhaps 15mph. RR tire hits small area on rounded curbing where a small piece of concrete curbing (perhaps 3” wide by 8” high) had come out. Tire made contact with this area. Sidewall blew out. Had to have car towed and new tire installed. Over $400. I contacted Continental USA and opened a case. They said there was nothing they could do. Suggested I have the tire dealer call them. Discount Tire, who took pictures of the sidewall issue, call Continental referencing my case. Continental told Discount Tire that they were unwilling to help. I have seen others reporting similar sidewall blowout issues on this tire. I am thankful I wasn’t traveling any faster. At the time of this incident, the 2026 Audi A6 Allroad had only sixty (60) miles on it!
