I WAS DRIVING OUR 2006 GMC ENVOY DENALI AT ABOUT 45 MPH WHEN THE LEFT FRONT ABS ACTIVATED. IT WAS AN UNNERVING EXPERIENCE AND HAPPENED SEVERAL TIMES. I HAD THE SENSATION THAT THE VEHICLES WAS INSTANTLY PULLING TO THE LEFT WITH THE ABS DRAGGING THE LEFT FRONT BRAKE. I TOOK IT TO THE DEALER WHO CLEARED 5 CODES RELATED TO THE FRONT ABS SENSORS AND BRAKING SYSTEM. I'M A MEMBER OF AN ONLINE FORUM CALLED WWW.TRAILVOY.COM I SEARCHED THE FORUMS FOR "BRAKE SOFTWARE" AND FOUND MULTIPLE COMPLAINTS THAT REFLECT MY EXPERIENCE. THE DEALER, DANIELS CHEVYLAND TOLD ME THAT THEY HAVE HEARD THIS COMPLAINT, AS WELL. I AM VERY CONCERNED THAT IF THIS OCCURS ON GRAVEL, WET OR ICY ROADS THAT AN ACCIDENT COULD HAPPEN. THE DEALER TOLD ME TO KEEP DRIVING THE VEHICLE TO SEE IF IT HAPPENS AGAIN. THEY SUGGESTED THAT I BRING THE VEHICLE BACK TO HAVE THE BRAKE COMPUTER FIRMWARE UPGRADED IF THE PROBLEM OCCURS AGAIN. THEY WERE NICE ENOUGH TO SAY THAT THEY WILL DISCOUNT THE COST OF THE FIRMWARE. *TR
