    It ended up being a bad coil pack.

    Dealer is sending a tow truck to pick it up and bringing me a rental car. I posted to see if anyone else was having a similar issue and knew what was causing the problem.

    We purchased a 2021 Yukon Denali a week ago. 3x now, several lights have came on and the 1st time a VERY strong rotten egg/Sulfur smell (cat. Converter smell)... Shut the engine off and all lights go off until you drive it again for about 30 min then come back on. SERVICE ESC, SERVICE STABILITRACK, SERVICE TRACTION CONTROL, FRONT END COLLISION AND CHECK ENGINE. Right before these lights all come on the vehicle starts to idle very rough almost like it has a miss in the engine and continues until you shut the engine down.... HELP, we have less than 450 miles!!!!!
