2007 suburban service Stabilitrack &TC light on

Thank you for all feedback. What does a bad ignition coil have to do with a TC? Or I also read dirty MAF and or TB.
I think these ate secondary issues non direct to cause

Any time the computer senses that there is something wrong serious enough to prevent the engine from running at top performance, it will disable TC/Stabilitrak, hence the warning indications. That's why you need a Tech2 to diagnose it - it will show you what is preceding the TC/Stab warnings.

When my service stability warning kept flashing across the info screen in my 2006, it was due to a wire shorting out that had been chewed through about a year ago, under the front passenger seat that ran to the yaw rate/accelerometer sensor, which is wired into the airbag harness under the front passenger seat. When it was in getting an oil leak fixed in October of 2020, a mouse got into it somehow while it was up on the rack overnight and chewed through the harness under my front passenger seat. I thought I’d patched up all the wires, but in November the service stability system warning kept flashing. My tech2 led me to the sensor under the front passenger seat not having to correct voltage. When I unbolted the seat there was one extra wire going into the harness that was chewed through and shorting out. Patching up that wire fixed my issue.

I have had the same issues. This has been going on for about 2 years. Scanned and side wheel speed sensors. Replaced all 4. We were good for 6-months. Now get random and starts to shift hard. Took to get scanned when the lights were on and no codes. If will go off on its own and run fine. No check engine light ever comes on. At a total loss. I have replaced the air shocks and pump a few years ago.

Could be many things, including the steering position sensor. You need a scanner that can read codes from the BCM, not just the engine codes. Do you have access to a Tech2 or equivalent?

I had intermittent stabilitrac and TC lights as you describe on my 07 Tahoe for almost 1-1/2 years before it stayed on steady.
Knew someone with HP tuner, so we hooked up and went for a drive. Turned out to be a rear AXLE/wheel sensor was not working. Purchased one and solved the problem.

Or I also read dirty MAF

I recently experienced this when I forgot to plug the MAF back in after replacing the air filter element.
