PROBLEMS WITH 2003 CHEVROLET TRAILBLAZER RESULTING IN AN ACCIDENT.*MR WHEN THE CONSUMER ATTEMPTED TO APPLY THE BRAKES, THE VEHICLE STARTED TO SKID. THE CONSUMER TRIED TO TURN THE WHEEL TO STRAIGHTEN OUT THE VEHICLE, BUT THE BRAKES LOCKED AND THE STEERING WHEEL CONTINUED TO GO TOWARD THE LEFT. THE CONSUMER WAS UNABLE TO MAINTAIN CONTROL OF THE VEHICLE AND SUBSEQUENTLY COLLIDED WITH A SEMI TRACTOR TRAILER. AFTER THE IMPACT, THE CONSUMERS VEHICLE CONTINUED GOING LEFT TOWARD ONCOMING TRAFFIC AND EVENTUALLY WENT LEFT INTO A RAVINE/DITCH. THROUGHOUT THE ENTIRE INCIDENT, THE CONSUMER HAD HER FOOT ON THE BRAKE AND THE VEHICLE WOULD NOT STOP OR SLOW DOWN. THE CONSUMER ALSO STATED THE AIR BAGS NEVER DEPLOYED. *JB
