FYI, for everyone. I had a few problems with my suburban 2007 LTZ. I’m an expert mechanic and found a simple solution to a lot of the stupid problems. Including Stabilitrak. I bought HPTuner software. I went into my computer and have disabled many many things, if you do this watch a lot of videos and be careful. If you change some setting in your computer you could really screw things up. But I think it was $150. Not sure I’ve had it for a long time. But LOVE IT You can do wonders with it. Good luck.
