NHTSA Complaint #10587543 — 2006 CHEVROLET TRAILBLAZER EXT

UPON TURNING THE FOUR-WHEEL DRIVE ENGAGED UNKNOWN TO ME AT THE TIME BECAUSE THE SELECTOR SWITCH DID NOT INDICATE THIS.THE TRUCK BECAME DIFFICULT IF NOT IMPOSSIBLE TO TURN AT LOW SPEEDS AS THIS VEHICLE DOES NOT HAVE A LIMITED SLIP DIFFERENTIAL IN THE FOUR WHEEL DRIVE MODE. WHILE TURNING THE TIRES ON THE OUTSIDE OF THE TURN MAKE A LARGER RADIUS THAN DO THE INNER TIRES.WITHOUT ANY SLIP THE VEHICLE TRIES TO MAINTAIN THE SAME LINEAR FOOTAGE TRAVEL BY EACH TIRE. THIS CAUSES THE TIRES TO BIND LOCK UP AND SKID DURING TURNS. I HAVE RESEARCHED THIS PROBLEM ON INTERNET FORUMS AND IT SEEMS TO BE A QUITE COMMON OCCURRENCE AND COULD CAUSE CRASHES WHILE TURNING. I HAVE CONTACTED THE MANUFACTURE AND THE RESPONSE WAS FOR ME TO TAKE IT TO A DEALER AND PAY FOR THEM TO LOOK AT IT. I DECLINED THEIR SUGGESTION AND OFFERED THE COMPROMISE OF TAKING IT TO AN INDEPENDENT MECHANIC AT MY OWN COST,TO WHICH THEY DECLINED. PLEASE NOTE I DID NOT ASK THEM TO REPAIR THE VEHICLE AT THEIR COST BUT ONLY WANTED THEM TO EXAMINE THE VEHICLE FOR DEFECTIVE DESIGN/MATERIAL. *TR
