NHTSA Complaint #11677928 — 2024 SUBARU IMPREZA

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.
