2025 CT5V Blackwing
My 2025 CT5 BW only has 322 miles. This afternoon while sitting at a traffic light, the engine started running rough and the check engine light came on. At the same time the SablilTrak inoperative warning light came on. I have made an online appointment at the local dealer for Tuesday, and I am trying to be optimistic about a quick fix. In the meantime, here I am asking if anyone has experienced this issue.
 
My 25's exhaust flapper valves somehow become unplugged which triggered a code. No other issues than that other than the oil plug press in.

Production was in December 2024.
 
Had injector bad on different chevy do the same thing with the same lights.
MY26 engine light was on and off 4 times from few hundred miles until 800 miles, dealer replaced injectors, fuel rail on one side of motor and bled the intercooler system, has been fine 1200 miles since.
