I was getting very annoying messages on my 2007 Suburban 1500 LTZ; traction control off, service stabilitrack, service brake system, with very frequent (and extended) dinging. Someone mentioned on one of the forums his was caused by low brake fluid. My brake fluid was about 1/16 inch below the minimum mark, I filled it to the max mark and it has completely stopped the dinging and error messages.

These forums are awesome!!
