NHTSA Complaint #11438870 — 2005 TOYOTA SIENNA

215/65 R 16. Four new CONTINENTAL tires fitted early 2021 to Sienna at Discount Tire in Tucson. July 2021 severe vibration and evidence of tire structural issue photographed. All tires showed similar failure mode.. this was on a very hot day. I took the vehicle to Big O tires and had the front two replaced at my expense so the vehicle was drivable. I returned to Discount Tire in Tucson (Speedway) to ask for a recall check after I learned of the 2021 recall on similar Continental tires for sidewall failure. Discount tire reimbursed one tire. I complained to agent Matthew Harby that the other two tires were dangerous because they showed the same sidewall defect on the hot day. He denied my request for replacement if the remaining two Continental tires because there was no open recall on these. I told I him I was worried about a catastrophic failure in normal operation. I then resumed driving. The weather cooled off and until October the two tires behaved normally again.. On 10/30 about 630pm I was dri ong on I10 and experienced catastrophic tire failure in the outside lane speed approx 65mph. I was fortunate to be able to pull over without losing control but the photo shows the extent of this serious failure. I am now at Discount Tire on Ina Road in Tucson requesting replacement of the failed tire and the final remaining CONTINENTAL tire. The photos should show sufficient evidence of sidewall failure matching the failure mode of the recalled tires. THESE ARE DANGEROUS AND NEED NHTSA ACTION WITH A UNIVERSAL RECALL BEFORE A FATAL EVENT OCCURS
