My 2021 GMC Sierra AT4 with the 3.0 Duramax (55k miles) just started making a terrible clacking noise while driving (approximately 40-45MPH). I looked at my display panel and didn't see any warning lights? I pulled over & killed the engine, checked my oil -fine - and looked for anything out of the ordinary - nothing? Started it back up, the noise was still there, crawled underneath to see if I could pin point the racket, and the best way I can describe it is it sounds like there is something clacking around in the oil pan? I had to get it off the side of the road so I drove it roughly 2.5 miles to my house. While driving, I also noticed that when I accelerate , it would miss out, but gradually gain speed. Still no warning lights? Any help or guidance would be appreciated.
