I checked my dash for any error codes and there were none. The oil pressure, temp, and transmission temp gauges all read normal. I stopped and topped the gas tank off with premium gas and checked the oil level, which was good. I was able to limp the truck back to my house. The next morning when I started it, there were error codes and the engine was still making the popping noise as well as a louder knocking noise. I started researching the symptoms, called two local independent shops and concluded the DFM system that shuts cylinders off to conserve gas has failed and caused the lifters to fail. I was told the failed lifter could and probably did damage the cam shaft(s). If I kept driving it, the camshaft damage could cause complete engine failure and more safety consequences. One shop quoted $5000 to replace lifters and $8000 if the camshafts were damaged. The other shop was similar, but offered a rebuilt engine for $12,000 because the lifters, camshafts, and new GM crate engine were all back ordered with no ETA from the local Chevy dealership. After weighing my options, and needing a truck, I decided to trade in my damaged truck. I contacted the GM concierge on XXX and was told to call back when the dealership had my damaged truck and could diagnose it. On XXX I called them back and they said they wouldn’t help because I traded it in. I had no plans to trade it before the engine failed and took a substantial hit on the trade in price that GM should have helped with to cover their faulty DFM system that caused the lifters to fail, which the dealership confirmed was the problem. They said they wouldn’t know if the camshafts were damaged until they took it apart, which they decided to not do and send it to auction instead.
