In Sept. 2024 we noticed that the edges of both front tires (Alenza 235/50 R20) had pieces coming off them so we arranged to have the tires replaced at the original dealer from which we had bought the car. They agreed that the tires were failing and replaced them. At that point the tires had only done 11827 miles so I asked if a warranty was applicable that would allow me to get back some of the replacement cost for the two tires. The dealer (Hazelwood Volkswagen of Bremerton, WA) said they would make inquiries and I paid the full price in the meantime. Despite numerous follow up inquiries, as well as contact with both VW USA and Bridgestone, I have not received any response. The suggestion seems to be that original equipment supplied with a new car are not covered by any warranty. After the tires were replaced I turned off the lane assist feature on the vehicle as this often seemed overly active due to random road markings. So far we have put about 3500 miles on the new tires and they seem fine. I have pieces that chipped off the old tires, and the dealer said they would hold the old tires pending a warranty response but that was in September 2024.
