have a 2010 LT 2.2l, The past couple of days my ABS and TC light come on. I would also get these messages: SERVICE TRACTION CONTROL, SERVICE ESC and ESC OFF. Car drives and feels like nothing is wrong. Turn car off and bring my son into daycare and then start car back up. The TC light does not come on and the ABS light comes on but goes back off withing a minute. I've checked all the fuses and they are good. What is required to service the TRACTION CONTROL and ESC? Also stopped by AdvanceAuto to see if they can get any codes with these lights on, they can't.

 

Check the wires at the cam solenoids on the left by #1 spark plug.
Check your oil level and condition, dirty oil can cause this.
You state your HHR is a 2010, if it's still the original battery have it checked

 

Just did an oil change about two weeks ago. Will check the battery later on today.Do you have to take the air filter off to check the wire. (Check the wires at the cam solenoids on the left by #1 spark plug).

 

Could be a bad hub, or ABS connection/wire.

 

Yes you will need to remove the air filter housing

picture above is from battery area. battery is good with a date of 06/15
Where does these two hoses connect too?

 

The gray hose connects to the hole on the side of the battery and the other end goes ot the hole in the floor; it's a vent. That's the only tube I see in the pic.

I suspect the crayon goes into the Crayola box under the front seat.

 

Double check the ground connection!
Replace the cracked grey tube for the vent

 

Just checked the battery and there is no place to put the vent hose into.
