It shouldn’t affect driveability but you should have it looked at.

What vehicle? We had a GMC Acadia and that was a never ending rabbit hole.

2015. We bought it used in 2019. It's only got 55K on it. No other problems.

Mine was an older 2011. It was good and still managed. I was just done stressing over it.

I’ve had that light coming on in my truck for five years. I’ve ignored it. But that’s not necessarily a good thing.🙂

That dang light has been on for most of the 21 years I've had my 2002 4-Runner.

Have you been losing a little power or has it been throwing a check engine code?

Also is the vibration as you accelerate or slow down?

It's throwing a check engine code and the vibration only happened while it was

The traction control automatically resets when you turn off your car for a few minutes.

It could also be a wheel speed sensor. Those are pretty easy as well.

I really think it is a dirty throttle body though. I wish I was in your area and I would bring by a Chevy code reader.

Thanks! I'm going to try this.

If anyone cares for the rest of the story...it was the alternator. It failed
