Cruise Control problems of the 2007 Chevrolet Trailblazer

This issue occurred about 6-7 times throughout my 15 mile trip. My travel was on a highway and speeds were between 55-68 m. P. H. At the onset of each occurrence. I would hit a bump in the road (not a major one ¿ just a bump) and then the ¿stabilitrak active¿ light would be illuminated in the dash continuously blinking like it's stuck. Then: -the truck would become sluggish dropping speed and knocking off the cruise control -you can¿t accelerate -the steering locks up sort of causing it to feel like the truck is out of control, this occurring at highway speeds -the amount of power used by stabilitrak was immense ¿ the headlights began to dim the longer it was stuck in this state -if you try braking during these spells it has the anti-lock active so you¿re just grinding away like you¿re in a skid but not stopping (and this is on dry pavement!) -- this occurred one time while I was on an exit ramp and and I was unable to slow thankfully I had taken the ramp a little slower to begin with or I could have been in major trouble in the curve then suddenly as quick as it all started it releases ¿ the light shuts off and all returns to normal.
