NHTSA Complaint #10342603 — 2008 GMC ACADIA

MY 2008 GMC ACADIA HAS TROUBLE ACCELERATING/MERGING INTO TRAFFIC. THE TRANSMISSION, AT LEAST ACCORDING TO A GMC SERVICE WRITER, IS DUE TO GMC'S TRANSMISSION DESIGN. IT WAS INTENDED TO UPSHIFT AND EVEN SKIP GEARS, IN ORDER TO CONSERVE FUEL. I UNDERSTAND THAT THIS WAS "CORRECTED" IN LATER YEARS. THE DEALERSHIP SAYS IT IS "NOT A PROBLEM, IT IS THE WAY IT WAS DESIGNED TO OPERATE". IF THAT IS THE CASE, THEN WHY WAS IT CORRECTED IN SUBSEQUENT MODELS? ENTERING TRAFFIC IS DANGEROUS, THE TRANSMISSION "LAGS" AT ALL THE WRONG TIMES, AND ACCELERATING TO PASS, OR WHILE CHANGING LANES, PRODUCES THE SAME LAGGING EFFECT, THEREBY CAUSING MY VEHICLE TO BECOME A ROAD HAZARD! THIS IS TOTALLY UNACCEPTABLE TO ME, AND AFTER SPENDING ALMOST $30,000 ON THIS VEHICLE IN 2010, I DO NOT FEEL I ALONE, OR I WHILE DRIVING WITH MY FAMILY, SHOULD BE SUBJECTED TO THIS DANGEROUS AND HAZARDOUS SITUATION 90% OF THE TIME WE ARE ON THE ROAD. *TR
