I have a 2011 suburban.
In hot day, the traction control come to off automatically and alert light to be on. I have not ABS alert light. During the light on, I can drive my car with no problem. In cold day, this phenomena don't occur.
Please let me know what sensors are broken or how to repair this issue.

Thanks,

 

I'll wager a guess..
Quick & Easy first step: In the wheel well, attached to the upper A-arm, there are plastic electric connectors that hook up to wheel-speed sensors - they're notorious for jiggling around or getting dirty and shorting out.
If it's not a bad connector - it could be a bad sensor. Local autoparts store should be able to read the code for you to know which one is bad.

Thank you for your useful comment.
I'll check them later.

But for these electrical issues, we need a diagnosis by a dealer or a autoparts store...
OK, I understood.

Thanks,
