NHTSA Complaint #11548887 — 2019 BUICK ENVISION

I'm recalling an incident I reported last year. GM refused to honor the service bulletin, and Palmen Buick GMC Cadillac in Kenosha, WI refused to work with Michelin. At 30,000 miles, I now hydroplane, and when I had my car serviced a few weeks before my warranty was set to expire, the dealership again refused to honor the prorate chart for the tires, and again tried to just sell me new ones. I provided a picture of one of the tires now, and you can clearly see how they have deteriorated. I IMPLORE YOU TO MAKE A FULL RECALL. GM IS CLEARLY AVOIDING THIS ISSUE, AND THEIR DEALERSHIPS WILL NOT WORK WITH MICHELIN TO CORRECT IT. Below is the original complaint. Tires are measuring low tread (4/32in) under 27,000. At under 25,000 miles on 6/17/2022, my vehicle experienced a blowout at low speed (approx 20mph), minutes after it had been parked. No pressure sensors were alarming until the blowout occurred. I have a case with Michelin, but the dealership won't contact them. I have a case with GM, but they will not honor the existing service bulletin [XXX] for ANY of the tires, stating it does not appear under my VIN. I'm fortunate this event occurred at low speed, but given the quality of these tires, I'm sure others have not been so lucky. I believe this to be a safety issue, not just a manufacturer defect.
