GMC ENVOY 2002 SLE XL PURCHASED IN THE MONTH OF JUNE AND STARTED HAVING PROBLEMS IN OCT. THE VEHICLE WOULD SHIFT IN AND OUT OF 2WD AND 4WD ON IT'S OWN AND ON OCCASION IT WOULD LOCK THE WHEELS ALSO. PROBLEM MOSTLY OCCURED WHEN MAKING TURNS. STATED PROBLEM TO DEALER (10/18/02) - DEALER REPLACED 4WD SELECTOR SWITCH (REASON: INTERNALLY SHORTED). HAD PROBLEM AGAIN IN MONTH OF FEB. '03. BROUGHT VEHICLE BACK TO THE SAME DEALER AND EXPLAINED PROBLEM AGAIN (02/21/03). DEALER REPLACED 4WD SELECTOR SWITCH AGAIN. REASON WHY I'M FILING THIS COMPLAINT IS BECAUSE I FEEL THIS VEHICLE IS NOT SAFE. I ALSO REALIZED THAT I'M NOT THE ONLY ONE EXPERIENCING THESE SAME PROBLEMS. MY HOPE IS THAT GMC WILL TAKE NOTICE AND CORRECT THIS PROBLEM QUICKLY.

POWER TRAIN:AUTOMATIC TRANSMISSION
THE TRANSMISSION FAILED IN MY 2003 GMC ENVOY WITH APPROX 95,000 MILES. WHILE DRIVING DOWN THE ROAD I WENT TO PASS A SLOW MOVING VEHICLE. AS THE TRANSMISSION DOWN SHIFTED THERE WAS A "BANG" SO I PULLED OVER TO LOOK UNDER THE TRUCK, AND MADE SURE NOTHING HAD FALLEN OFF. I GOT BACK IN THE S.U.V. AND MADE MY WAY BACK HOME WITH NO PROBLEM. THE NEXT DAY WHEN I WENT TO BACK OUT OF MY DRIVE WAY THERE WAS NO REVERSE. I CALLED A LOCAL GM DEALERSHIP AND WAS TOLD THAT THE PROBLEM APPEARS TO THE SUNSHELL GEAR. ACCORDING TO MULTIPLE POST ONLINE, SEEMS TO BE A COMMON FAILURE AMONG ENVOY'S AND TRAILBLAZER. I CHECKED THE FLUID AND IT APPEARS TO BE FINE, NOT LOW, NOT BURNT, AND STILL RED AND CLEAN. *TR
