general problems of the 2012 Toyota Sienna

The contact owns a 2012 Toyota Sienna equipped with michelin tires, tire line: cross climate 2, tire size: 235/60/r17, dot number: (n/a). The contact stated sidewalls on all four tires were expanding, causing the tires to bubble and bulge outwardly. The dealer was not contacted. The contact informed the tire shop where tires were purchased of the failures, and two tires were replaced. The contact was unsure what two tires were replaced. The manufacturer was made aware of the failure. The vehicle failure mileage was approximately 152,000 and the tire failure mileage was approximately 1,000. The VIN was not available.

Costco installed 4 tires on my 2012 Toyota Sienna on 11/10/2021. The tire had 80,000 mile warranty. At the time of tire installation, the mileage on my vehicle was 253,405. I did my tire rotations every 5000 mile at suburban Toyota in farmington hills. I took the vehicle for tire rotation at 283,618 miles and the dealership refused to rotate the tires because the tread was below 3/32 seconds. I thought that this was a mistake and went again to rotate the tires at 288,789 miles. I went to costco on the same day and told costco representative at the counter mr. Sam provenzola that the tire needs to replaced under warranty. I informed him that I drove only 30,000 mile on the tires. He checked all my mileage papers when I did the tire rotations. He went inside and talked to mr. Randy lanning (tire section manager) and told me that the tire need to be under 2/32 seconds for michelin warranty to work. I asked him to arrange a tire rotation and scheduled the tire rotation on 12/20/2022. I took the vehicle to costco on 12/20/2022. The mechanic called me after 30 minutes and informed me that the tire tread is under 2/32 second and cannot be rotated. I talked to sam about it and he went to talk to randy. He told me that the mechanic is going to rotate the tires and I can come back after one month to check the tires again. I informed sam that he, costco, and michelin are playing with the safety of my family. He told me that costco is not concerned about the safety of my family. If I am concerned about the safety of my family, I should change the tires without the warranty. I believe that costco and michelin are installing 30,000 mile tires as 80,000 mile warranty tires. I drive most of my driving on the freeway and on cruise control. So there should not be any issue with my driving. I got tires from discount tire company before and had no issue like this. I request nhstb to investigate the issue and warn people of this issue before people die.

I am complaining about the michelin primacy mxv4 tires. The tires have a 60,000 mile warranty and I have only gotten 20,200 miles out of them. The tread wear is a 5/6 gauge. I will have to purchase three new tires very soon, before the tires start balding, in order to correct there failure. I started out with four of them, but now I am down to three. One of them had a screw found in it, so I replaced it with a new firestone tire.
