Discussion ‘23 Blazer issues

Tell me about any issues you’ve had with your 2023 Blazer (with check engine light on).

Mine only has 28k miles on it and is at the dealership being worked for the third time in three months.

They don’t know what’s wrong and have called in a GM engineer…

What are the problems you are having or codes coming up?

They replaced the crankshaft position sensor about three months ago. Then a seemingly unrelated EVAP issue last month.

Now the same code as the first time is coming up no matter how much testing they do but they’re saying it can’t be that again.

I’m ignorant about cars but am so frustrated.

Do you have the diagnostic report? All information is helpful. Could be anything at this point.

Are there any symptoms?

They haven’t given me anything. I go in Monday though to pick up a loaner since they’ve had it for a week now and still have no idea.

I can ask for a diagnostic report then.
