Tire Related Problems of the 2019 Lexus IS

Tire problem

On Saturday 3/14/26, while driving on florida's turnpike at highway speed, without interior dashboard warning lamps or other warning symptoms both rear tires failed simultaneously & disintegrated creating a potentially catastrophic driving hazard for those with me inside the car as well as others on the turnpike. This type of failure occurring at the same time on both rear tires with relatively low mileage of 27,680 miles raises concern about a potential defect. The rear tires are the original factory tires. I do have photos + video evidence of the damaged two rear tires which were replaced on Monday, 3/16. I no longer have the damaged tires, however it may be an option to speak with tire kingdom. I have attempted resolution immediately following the incident from Lexus of west kendall as well as bridgestone. The dealership leadership advised "I should be happy those tires gave you almost 30,000 miles since these oem tires should be replaced every 15,000 miles. " he replaces his own tires every two years. The service manager stated the problem was that I drove over too many potholes & curbs without having my car aligned. He also said he lives two miles from his job & dodges 15 potholes daily going to work. I have already met in person with the service manager & have had multiple conversations & email exchanges with dealership management including bridgestone. Bridgestone will only deal directly with the dealership. I have provided photographic & video evidence of the tire failures to all. Despite these efforts, the Issue remains unresolved. Given the severity of the incident & the safety risk involved, I am requesting: immediate escalation to a regional case manager; a formal inspection & defect evaluation of the failed tires via photos & video; review for $758. 23 reimbursement under warranty or goodwill consideration. Please advise on next steps & confirm that this case has been escalated. I appreciate your prompt attention to this serious matter.
