Default Check engine light following 30k tune up

I just got my car back from the Lexus dealership last thursday after its 30k tune up, oil change etc.

This morning (wednesday) I get a check engine light plus all VSC, wavy traction thing, etc.

It was extra cold last night...and it happened when I first fired the car up this morning.

I got gas two days ago as well.

I checked the gas cap and re-tightened it. I've take 2 small trips since.

Lights still there.

When do I take it back to the dealership?
(I checked the oil level too of course)

Why don't you take it to an AutoZone first and have the codes read, that will help pinpoint the situation.

Great idea...didn't realize Autozone did stuff like that.

Update:

So it was the gas cap after all. Which was the first thing I checked...and to me it never seemed "lose"...but oh well.

Oddly enough, it took 6 days and 140 miles of driving for the lights to turn off. I had the codes pulled anyhow, because I thought this was a rather excessive amount of time....

So just for future reference....
