I have a 2011 Cruze LT and when I turn the key to the position one before starting it, the check engine light comes on. However, when I start the car it goes off. How could the check engine light be on without the car being started? Is this a problem? I'm fairly new to driving/cars and have never seen this before. Any help would be appreciated!

Not a problem.....that is a light check....proves it is functioning before you start the car, same as the other warning lamps.

Spend some quality time with the owners manual....this car has many things that you should become familiar with.

Welcome to the forum! I agree with Robby. Sounds like normal behavior. Also there is a ton of good information in the owner's manual. It's advised that you pick up the later 2014 owners manual due to some changes in GM's maintenance recommendations.

Welcome to CruzeTalk. You're seeing the normal operation of the instrument panel. Another item you're going to notice is a slight grind right as you pass 20 KPH (12.4 MPH) for the first time after you start your car. This is also normal and is the ABS self test to ensure the wheel sensors respond to the BCM (Body Control Module) computer.

Wow, that check engine light stated way back in 1980 on some vehicles, 1985 most of them had that light, in 1996 was the start of OBD 2 where on board diagnostics was suppose to be standardized for all vehicles.

We hope and pray that check engine light comes in the the run position, then goes off shortly after the engine starts. If it doesn't go off, then we have problems.

On your Cruze there is a female socket located on the lower left hand corner of the instrument panel. There you can plug in a scanner to find out why that check engine light is staying on.

If you live an an emissions testing area, and that light stays on, you will not pass the test, if you are my daughter, you will be calling me for help.

Can be a simple problem like your gas cap is loose, or something major that will cause your engine or transmission to burn up.

In my Cruze owners manual it tells me to go to my dealer for $$$$$, but they leave off the $$$$$ if the check engine light stays on, screw you, I have my own scanner and a heck of a lot more brains.

In my 88 Supra Turbo a display on its instrument panel tells me what's wrong for all five computer systems, I don't need to buy a scanner.

On my Chevy P-30 motorhome chassis, no check engine light at all, but very simple to find what the problem is, doesn't have all this new crap.
