2017 GMC Acadia

Tire size is P235/65R18 I purchased these tires in December of 2024. I am concerned that these tires were built without the correct compound to be qualified as an all-season. I have never had tires this bad in snow, even though they are all season brand-new tires with full tread. I immediately bought a set of snow tires for the vehicle. I again tried these tires in snow in November of 2025 after they had roughly 10,000 miles on them, and again found them to be the worst tires in snow that I have ever driven. I am concerned these were a mis-build.

The contact owns a 2017 GMC Acadia. The contact stated that while driving approximately 10-15 MPH, the vehicle made an abnormally loud blower motor sound while accelerating, before the vehicle lost motive power. The transmission was shifted to neutral(N) and pushed to the side of the roadway. The TPMS warning light was illuminated. The vehicle was towed to an independent mechanic who determined that the transmission clutch had failed, and the transmission needed to be rebuilt or replaced. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted and confirmed there was no recall coverage or warranty coverage on the VIN for the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 132,000.

235/65R18 all 4 tires worn down after 27,000 miles, suppose to have 60,000 mile tread life. took my Acadia into the dealer for regular oil change and was informed all 4 tires were worn passed the safety margin. He told me there was a service bulletin about the tires but since my warranty had run out there was nothing he could do. He never mentioned the service warranty or that the tires were wearing severly.
