I purchased a 2021 Suburban SRT Dec. 19 and on Feb. 19 I noticed a ticking noise coming from the engine (4,927 miles). While driving the vehicle home it was hesitating or misfiring at around 3,000 RPM's. The check engine light came on and the Electronic Stability Control (ESC) light came on as well. I just had it towed to the dealer today.

Has anyone had any similar issues and if so what was the diagnosis?

I had a similar issue except instead of the check engine light and ESC light, it was the service traction control and ESC light. Also was making noise during shifting like a 'clunk' noise. Towed to the dealer and they said it is a collapsed lifter in one of the cylinders. Looks like this is becoming an issue as the service manager said it was the second he'd seen so far, and we live in a smaller town. What happened with your situation?

ESC light and back fire noise as well as engine popping. Not sure sure what’s going on.
