I purchased Goodyear Assurance MaxLife 195/65 R 15 from Sam's Club in Kingston on August 2023. On [XXX] my tire blew out on the inner sidewall of my tire. When I spoke with an employee from the automotive department in Sam's Club about my tire, the person said " Let me guess, was it an Assurance MaxLife?" I said "yes, how did you know?" The employee said " this is like the 19th one with the same problem. I'm shocked their not a recall on them." So I paid for a new tire and the next day decide to check to if their was any recalls on the tires. I didn't find any. So I decided to make this report for others. Hope this help!

The car had about 8000 miles on it. It was parked in Garage the night before. In the morning the outside temperature was 39F. During my 30 minutes driving, the front defrost was turned on. Afterwards it was parked on driveway and at that time the windshield was fine. 6 hours later, I noticed a spiderweb like crack under the camera section on the front windshield. The crack was about 11 inch long. It looks like the glass could not handle the temperature change.

The right side outside mirror glass detached and fell off while driving down the road. There was no noticeable defect on the vehicle prior to this and no known reason for this to happen. The vehicle was operating normally and was not involved in any sort of unusual maneuvering or crash. Upon taking it to the Toyota dealership it was found that glass did in fact detach on its own and needed to replace the entire mirror mechanism. This is obviously a safety concern for the driver due to a required mirror missing and also a safety hazard that could impact another motorist by this glass flying and hitting another car.

I was driving to work into the garage. The entrance of the garage has a mild incline with a narrow entrance and I normally will slow down so I can steel the car slowly. I was going at about 10 to 15 mile speed and felt a stall first and then the car went into accelerated mode on its own. I felt the car was shift to a different gear on its own up to 80 to 100 miles. I am lucky there is a cement pole in front of me and the car went right into the pole smashing the left side(driver side of the car ) I have to step on the break to stop the car. It all happened very quickly within few minutes. I was lucky there was no one in front of me and I was not hurt. I never had issue with toyota car and this was the first time. I actually had car in the day before for 15,000 miles maintenance
