Every once and a while the heat gauge will cut out and the warning light will say engine over heating A/C disabled and the fans will kick in on high.. Well the engine is NOT over heating and if I disconnect the batt and reconnect it everything is fine for a couple days.. Now I have a 2 part question #1 what can be causing this and #2 the chime gos off for 10minutes when it happens and is there any waY I can dissable the chime in the dash? Yes it's a 2011 and it's warranty has run out so there's no way I'm going to the dealer, thanks

 

Bad temp sensor or short in the wiring are 2 possibilities.

I agree with "oldchevy", it sounds like there may be an electrical issue, just a suggestion, not a diagnosis. I recommend having the vehicle inspected for a more accurate diagnosis.

Well it's not the temp sensor.. I tried that. It does other crap too (traction controll) and I'm almost willing to bet its the ecu

 

To start check all ground wires including the batt. Clean the batt terminals. You state that if you reconnect the batt. it is OK for a few days.
