2019 GMC Sierra 1500: fire, smoke or burning smell

Filed Dec 22, 2025 · Engine · TX

We were driving down a farm to market road at about 50 mph pulling an empty cattle trailer when we had a severe power loss, lots of dash lights and warnings. I noticed white smoke coming from the tail pipe. We limped it back to the house and unhooked the trailer and idled it into the Chevrolet dealership in Portland TX. The dealership just called and they said the #5 cylinder failed, there is metal in the oil and it will need an engine replacement at a cost of over $11,000.00. The truck is a 2019 and has just over 54,000 miles on it. No engine should fail at 54,000 miles and no company should sell one that does. Pulling a loaded trailer at highway speeds with a total engine failure could easily cause death to passengers and livestock. 12122025

While driving on the highway, I got a message that said "low oil pressure, turn off engine" with red flashing lights. I could also smell burning oil and metal. I immediately pulled over and turned off my engine. When I exited my truck, I could see all of the oil that remained in my engine leaking onto the ground. My truck was towed to a local repair shop and they advised me that this is a common problem in this truck. The oil line blew likely due to a defective crimp. The mechanics can't repair the problem right away because this line is on a national backorder and there is no aftermarket option. This obviously happens too often if this part is on backorder. The mechanics believe there may have been damage done to the engine as a result of losing all of the oil on the highway.
