What 2026 Audi A6 Allroad owners say
Most recent owner complaints, unedited.
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!
