CT5-V STABILITRAK PROBLEM

[Daniel Goss]

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.

Scan it for some idea of what is going on.

My default for rando behavior is a flat battery. Does it sit around a lot or did you just take delivery? Either way if its not on a maintainer its possible the battery is barely charged enough.

Regarding battery, I just bought the car new about 3 months ago, so with just 322 miles, it is obvious that I haven't been driving it a lot. But when it is just sitting in the garage it is hooked up to a battery maintainer, which shows "fully charged - auto maintaining".

I guess it could still be a bad cell, but I guess you'll get a clue tomorrow at your appointment.

Sounds like it could be a bad injector like Comment 2 mentioned - that combo of rough idle and stabilitrak error is pretty common when the engine isn't running smooth.
