NHTSA Complaint #11425207 — 2017 TOYOTA SIENNA

on July 3rd, traveling on highway to airport tire blew out (right rear). Pulled to side of road and attempted assistance but this was friday afternoon before july 4th holiday, NOTHING was going to happen except a tow - possible wait as long as 2-3 hours. reportedly the Sienna has drive flat (50 miles at 50 mph) We drove 5 mph for approx 3 to 4 miles to tire store/Les Schwab. Flat was replaced but then on inspection ALL remaining tires had card showing wear on inner tires. ALL 4 (including the blowout). Pictures submitted . Of particular concern is that we had taken the vehicle about 10 K prior (March)specifically for tire wobble noise and to fix alignment. Wear was noted, but no safety concerns raised and no cautionary recommendations offered. When we brought the vehicle and tires to the dealer AFTER the blowout we were told by service manager that the early wear was a known problem to occur specifically on the all wheel Siennas. Again, NO CAUTIONARY ADVICE GIVEN in March despite recognized wear and this known history. We had a blowout in heavy holiday traffic at 60 mph less than 10K /3month later. This easily could have been catastrophic. We reported to Toyota to a "Beth" at customer documentation and risk reduction department who did an excellent job of deflecting causation/potential blame and advised us to contact the tire manufacturer or the dealer. Absolutely no evidence of concern for safety - ours or those around us - at highway speeds. Review of web shows known problem, service manager volunteered it to be a known problem of premature wear, with service given shortly before incident WITHOUT GUIDANCE. "Beth" told us she would document our concerns but that there was nothing Toyota could do or would do other than documenting. I am hopeful you can investigate further and initiate some reparative process before there is a preventable catastrophe much like the Prius accelerator problem. we will send copies of to wherever is useful
