Possible have a caliber not retracting all the way and the brake shoe is slightly scrubbing the rotor. Don't overlook the possibility of wheel bearings or CV joints.

How about a new wheel bearing?

The fan relay is stuck. It is a relatively inexpensive part. Your owners manual will tell you which relay it is and where it is located, most likely under the hood. Once you locate it, pull up on it to remove it and then take it to an auto parts store to get a replacement.

The lighter socket or the element.
Check the element for burn marks and the socket for debris blocking the contacts.

it could be a faulty brake switch, even the brake switch flicking would activate the abs/TC as computer would think its erratic driving.

yes a bad 02 sensor will cause the car to run badly. and change those plugs too

It could be the ETC sensor (electronic temp. control) which send a signal to the computer to tell the temp. and how to mix the fuel to the throttle body for start up and during the day. This switch looks like the engine temp. switch on the heads but they are not the same. The ETC is usually around the thermostat outlet not in the heads or intake. Just be sure you are changing the correct one. It is not hard to change, you may loose a little antifreeze when you remove it but it you are quick you can screw it right in and if you want you can drain the radiator down a little and then install it.

If it does it again go to a auto parts stor and ask them to put the scan tool on it and get the codes pulled. Write them down and post them on here. You may be able to get codes now. It probably stored the codes in the cars computer.

I had the same problem Its your security system failing it is really common in GM vehicles i guess. I took my car in and they wanted a ridiculous amount of money to fix it so i did some research and found a module that you can install yourself and it will bypassed it and i havent had a problem since the car starts every time and i did mine 5 years ago. they have great customer service and if for some reason it doesnt work they will refund you 100% of your money. I checked the list and your car in on there year make and model for the problem.. Hope this helps ya out
