NHTSA Complaint #11704128 — 2019 GMC SIERRA 1500

Just had my 2019 GMC sierra 1500 Denali engine fail. My truck has 75k miles oil changed regularly no codes, issues or dash lights. Recently had it at GMC I Folsom California for a rear window replacement. Full inspection with no issues and nothing found wrong. Sunday 12/7 with my girlfriend and son in the truck about to get on the freeway felt a weird shift as I got on the freeway on-ramp. As I went to accelerate I had my traction control lights come on, lost power, and flashing check engine lights limped the truck off the side of the freeway and exited to a gas station. My truck wasn’t leaking anything and oil pressure was good but it sounds like popcorn was being made in my engine when it was on. Had my truck towed to Folsom GMC and yesterday 12/8 got a call I need a new engine. Called GM corporate to talk to them and opened a claim. GMC dealership got an initial help with 15% of the bill telling me I would need to pay $13,315. Talked to the service advisor and they put in a request for help from GM. Today at 9:00 a.m. they offered 50% coverage and I was able to get a little more but it still has me paying $7,500 and it will be 2-3 weeks to get the repair done. The dealership also will be getting me a loaner vehicle. This dealership has not been great but with this they are trying and doing a lot. However 75k on a truck that does not haul or have heavy use and is 7 years old with no prior issues is crazy. I was told cylinder 8 showed a misfire. Once they opened it up there was damage to the pushrods, valves and lifters with significant metal throughout the motor. I’m still waiting for corporate GMC to get back to me and hoping they will help or offer more money off as this is still a very large bill for a single father of 2 around the holidays. I bought the truck used with about 32k on it in 2022 and have had no mechanical issues or codes related to the motor or transmission.
