2024 Subaru Impreza

Yokohama Avid (front x2) 4UT76EX1623 and (rear x2) 4UT7EX1723 225/40R18 while the Passenger Front (4UT76EX1623) tire completely blew out the sidewall after third party inspection all 4 tires on my New 2024 Subaru Impreza are failing per the tire technician "after inspection it appears that all four tires show significant premature tire wear on the vehicle". Alignment preformed April 10, 2025 by DCH Subaru of Riverside and again alignment and suspension were checked the day after blowout of tire on July 28,2025 by American Tire Depot " no issue found with the vehicles suspension and alignment is within specs at this time". I was driving on a mountain road approximately 25 MPH when blowout occurred. Significant POP sound heard and vehicle TPS system immediately alerted us that the tire pressure dropped to 0. Tires had been maintaining tire pressure well before the incident. The "significant premature tire wear" is indicated by a noticeable crack that appears around the sidewall of all four tires as well as the steel cord showing significantly along the inner wall of the tire that blew out. This was only visible after removing the flat tire to apply the spare.

Front driver side tire sidewall bubbled at 7900 miles on a 2024 Subaru Impreza on June 22nd. They are the original equipment tires: Yokohama Advan S34P P225/40R18 88V. A sidewall bubble is a sign of a structural failure and indicates the tire will eventually blow out. This can lead to loss of control as well as sending debris towards other road users. No warnings or tire pressure changes occurred. There was no impact, only normal highway driving prior to the damage. The damage was not present prior to 300 mile road trip, but was present upon arrival at our destination. The problem was immediately reported to Capitaland Subaru who the vehicle is leased from. Initially they refused to let me bring it in. Eventually they did get me an appointment for June 30th, and they allegedly inspected the tire at that time. They told me to keep driving on it until the warranty replacement was approved. A warranty case was never opened by the dealer. 17 days later, I received a call from the dealer saying I must open the case with Yokohama myself. The vehicle comes with a sealed kit of owner's documents and booklets including tire warranty information, but it contains Goodyear and Bridgestone warranty info and not Yokohama, which is the OEM tire on Subaru Imprezas. I had no info on my warranty nor a guide on how to submit such a claim. After searching online, I did so and gave the case number to the dealer, but I have not gotten any notification since. It has been well over a month and I've logged over 1300 miles on the damaged tire. The car now has significant vibration coming through the steering wheel as of 7/30/25. Dealer was supposed to provide a loaner but did not. The manager has made no attempt to address the issue. A complaint has been filed with Subaru corporate as well.
