2025 Hyundai Santa Fe

255/45R20 We had a front driver tire get a bubble on our way to Florida. Had it replaced in [XXX] . On our trip back we had a blowout to the passenger front on XX just outside of [XXX] , in a very vulnerable area on the left side of the road. Called Hyundai SOS and they had AAA come. Got my wife out through the drivers door and over the guardrail while we waited. Called [XXX] as the traffic was flying by and the car has very little room on the berm. The tire blowing had no warning. Got a new tire the next day in [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Have had two sidewall bubbles appear, one was right front tire with approximately 7000 miles, second was left front tire with 11,500 miles. Both were OEM equipment on 2025 Hyundai Santa Fe hybrid limited fwd. Tire size 255/45/R20. No blowouts. Replaced tires at great expense and inconvenience immediately upon finding bubble on sidewall.

I am reporting premature tire wear on OEM Goodyear Assurance 235/60R18 tires installed on my AWD 2025 Hyundai Santa Fe SEL (VIN: [XXX] ). Component/System: OEM tires; documented and can be inspected at the dealership, which serves as a neutral, third-party verifier, or via submitted records. Safety risk: AWD vehicles require uniform tires; uneven tread risks drivetrain damage and unsafe handling, endangering myself and others. Confirmation: PA state inspection (11/17/2025) at 6,172 miles: Rear 3/32”, Front 5/32”. Dealer Delaney Hyundai (RO# 494892) documented the issue. Current mileage 7,074; tread wear ~1/32” per 881 miles, estimated current depth Rear 2/32”, Front 4/32”. Inspection: Documented by dealer and PA inspection; no manufacturer inspection yet. Warning symptoms: None beyond premature tread wear. Phone attempts to manufacturer: [XXX] (10:54, 7 min, snarky, refused escalation), 11:02 – 15-min hold no answer (son’s phone 8 min hold); [XXX] (11:17, 35 min), insisted on retail Goodyear center, finally agreed to supervisor callback (24–48 business hours). Requested resolution: Corporate review and replacement of all four OEM tires, including mounting, balancing, and disposal, coordinated with dealership documentation and PA inspection. No retail Goodyear referral should be required; inspection is only for verification as part of corporate review.

Pirelli Scorpion MS 255/45 R20 105V M+S A large bulge was found on the inside sidewall of the tire immediately adjacent to the tread. We had it inspected due to a slight shimmy in the nearly new (<3000 miles) vehicle, which had been present since delivery when traveling at highway speeds. We were told that the car was unsafe to drive but neither the dealership where we bought the vehicle and the dealership where we were having it serviced were willing to provide any relief (loaner, warrantee or discounted tire(s), etc.) Pirelli indicated that they may cover it under warrantee but that the tire would need to be shipped to them for inspection to determine if the condition was due to a defect. We drove it slowly home and after a few days of not driving it while trying to get some assistance, we purchased 4 new tires. We were able to find approximately a dozen other similar reports for 2025 Santa Fes with the same tires that had experienced the same issue; one such report indicated that 3 out of the 4 original tires all developed a bulge on the sidewall. When I first attempted to purchase new tires at Costco, the manager "refused" to sell me tires because he insisted that it was a defect and that the dealership should replace it but they did sell them to me after the dealership again refused to do so. We did not retain the tire and the only people to inspect it were the technician at the dealership where we had it serviced and the manager of the Costco tire center. There were no warning lights, but there was a slight shimmy at highway speed (~70 mph) from the time we took delivery until we replaced the tires. The defect was on the inside sidewall and was not readily visible when the tire was installed.
