Consumer Description

On [XXX] at around noon I was driving my 2020 GMC Sierra northbound on [XXX] 26 miles north of Moab Utah. My truck died and I attempted to coast to the next passing lane but did not make it. The shoulder was about 3 feet wide and then had a steep drop off. I pulled over as far as I could but the majority of my truck and trailer was still in the only northbound lane. The northbound traffic was forced to cross over the double yellow into the oncoming southbound traffic. The concern was getting rear-ended by northbound traffic behind me or a head-on collision with the northbound traffic veering into southbound traffic. I made several attempts to restart the truck and the dash just goes blank with no attempt from the starter. We waited for a tow-truck and about an hour into this wait Utah Highway Patrol arrived and parked behind us with his lights on warning traffic from both directions. There were no precursors to this failure or notifications. I didn’t even hear any noises. There was no physical damage or any leaking fluids. It just quietly stopped. John Elway Chevrolet informed me the bearings failed and the engine seized. I wanted to keep the core for evidence due to learning about the numerous catastrophic failures of the L87 engine I had. Keeping the seized core was going to cost me double the cost of a rebuilt one ($7000). When I asked the service Manager, Ben why its twice the cost? He said, “GM doesn't want you keeping the core and they can set whatever price they want .” I have had this truck since it was new (6 miles) and noticed unusual oil consumption early on. I would never make it to the next oil change without having to add oil, even with the very first oil change. I inquired about this with the dealer and told this extreme oil consumption was normal and given Bulletin 01-06-01-011M. I did not involve my insurance because they do not cover engine failure. I paid $12,653.97 for a remanufactured long block. Of that was $2469.93 was for parts not need INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INF
