NHTSA Complaint #11639255 — 2024 GMC SIERRA 1500

Truck with >15000 miles on it suddenly stops on highway (Dec 6, 2024). Engine won't start but all electrical components work, retractable steps, radio, bluetooth etc. When attempted to start, all electric went black and "push to start button again" came on display. Towed to dealer and after 3 days, advisor says it's not the battery but it might be something electrical. After six days I trade this truck in as they "don't" know what is wrong. After I trade they tell me that the truck needs a new engine but don't why. While taking my new 2025 truck in for a computer problem (500 miles) they tell me they found metal shavings in the oil. I find out two weeks later that there might be a problem with 877,710 6.2L engine with the same problem as mine. Sales says he doesn't know what problem is but he says he may be stuck with the truck for 30 days or more so I should trade.
