Owner report 11660464 · 2025-05-12 (May 12, 2025)
I am reporting a potentially serious and widespread safety defect involving Goodyear Wrangler TrailRunner AT tires installed as factory equipment on General Motors trucks. My 2025 GMC Sierra 3500HD Denali has just 5,800 miles. Both rear tires, with DOT code 2724, have developed identical sidewall bulges behind the “NER” in the “TrailRunner” stamp. These bulges are consistent with internal structural failure, not road hazard damage. The truck has never struck a pothole or curb, and there is no evidence of impact or external damage. I have pers…

weekly you will start the truck and have no audio of any kind. No blinker noises no collision warning noises, no radio, no on star noise. No sound at all and sound will never come back on until you turn truck off and wait 20 mins. GMC says it's a known software issue, but this has been going on since I bought the truck brand new back is April of 2025. I live in a hands free while driving state when it's come to cell phone use and can't even take a call with no audio of any kind. I don't see how GMC can say this isn't a safety issue.

“I own a 2025 GMC Sierra with 30,000 miles. The oil cooler failed and caused loss of oil pressure and potential internal engine damage. The dealership acknowledges the failure but refuses to escalate the case or perform a proper inspection. I am being instructed to continue driving the truck even though it may suffer catastrophic failure while driving. This is a safety hazard.”
