First off, I saw that there are numerous threads posted about the Stabilitrak/Traction control mysteriously turning off and the display showing the "Service Stabilitrak" and "Service Traction Control" signs. I know there are a million different reasons why this might happen. I was hoping someone could narrow down the issue based on the following observations:
- Only those two signs go off, no check engine light, no ABS sign, no reduced engine power sign
- Really happens randomly. I used to get it on a daily basis a few months ago, then nothing for a few months, and recently again almost daily. When the car is not in use, the signs reset
- I always happens when I drive out from a parking position or like 5 seconds after I drive out. Never happens when I've already been on the road. Feels like the signs tend to go off when I am taking a turn from the parking position or turning when I leave the parking area. That is to say, I did not notice the signs going off by turning on the car and driving straight forward or reverse.
- Steering wheel sensor: I was not able to trigger the signs by turning the steering wheel all the way in either direction. Tried it multiple times. Does that mean the steering wheel sensor is not the culprit?
- Wheel sensors: I pulled and pushed the wires on either side, and was not able to trigger the signs. Does it mean it's not the wheel sensors?
- Brake fluid: Just a little below Max level. Though I was ready that increased water content in the brake fluid from condensation can cause Stabilitrak issues? Is that true? How can I go about that?
- I read that a bad battery or a battery that is not able to deliver charge consistently can cause this. The battery charge has always been in the normal range, though recently I noticed once that the level was at the very lower range of normal (still normal though) and then later went back up to like the middle area of the range. Not sure if that means anything at all. I am not sure how new the battery is or if the previous owner had replaced it. On that note, ever since I bought the car last year, I have had a USB adapter in the cigarette lighter position plugged in at all times with a charging cable for my phone. Nothing connected to the adapter when I am not driving. Does that adapter pull any significant charge from the battery when the car is not in use, if at all?
It's a 2013 Tahoe LTZ with 88k miles. I don't have a Tech2, so have not been able to do more sophisticated diagnostics. Thank y'all!
