NHTSA Complaint #10534634 — 2007 GMC ACADIA

WHILE ON A VACATION TRIP WITH THE FAMILY, MY 2007 GMC ACADIA STARTED TO HESITATE AND BUCK WHEN ACCELERATING FROM A STOP. WHEN I ARRIVED AT MY DESTINATION AND PULLED INTO THE PARKING LOT, WHEN THE TRANSMISSION COMPLETELY STOPPED WORKING WITH NO FORWARD OR REVERSE GEARS. I HAD TO HAVE THE CAR TOWED TO A GMC DEALER AND HAVE A BROKEN 3/5/REVERSE (35R) WAVEPLATE REPLACED IN THE TRANSMISSION. THIS SUDDEN UNANNOUNCED LOSS OF POWER TO THE WHEELS, COULD BE A POTENTIAL CATASTROPHIC EVENT FOR THE CAR PASSENGERS AND OTHER VEHICLES, TRUCKS AND BUSES, IF THIS WERE TO HAPPEN ON A HIGHWAY TRAVELING AT 65 MPH, AS THERE MAY BE NO WAY AVOID GETTING IN AN CHAIN REACTION ACCIDENT WITH THE FOLLOWING TRAFFIC MOVING AT HIGHWAY SPEEDS. THIS COULD BE ESPECIALLY HAZARDOUS IN HIGH VOLUME RUSH HOUR TRAFFIC, AT NIGHT OR UNDER WEATHER IMPAIRED CONDITIONS (I.E, FOG, RAIN OR SNOW). AFTER A LITTLE RESEARCH, I WAS MADE AWARE THAT THIS IS NOT AN ISOLATED INCIDENT AND GM IS QUITE KNOWLEDGEABLE OF THIS WAVEPLATE TRANSMISSION PROBLEM, IN ALL MODELS WITH THE SAME DRIVETRAIN PLATFORM, BUT HAVE DONE LITTLE TO STEP UP AND REMEDY THE PROBLEM. IF YOU ARE OUT OF WARRANTY (5 YEARS OR 100,000 MILES) YOU ARE GOING TO BE OUT SEVERAL THOUSANDS OF DOLLARS FOR THE REPAIRS, SUFFER A GREAT DEAL OF INCONVENIENCE AND ARE PUTTING YOURSELF AND OTHERS ON THE ROAD AT GREAT RISK. I HOPE THIS WILL HELP BRING THIS ISSUE TO HEAD, AS GM NEEDS TO RECALL AND REPAIR THIS WAVEPLATE TRANSMISSION PROBLEM, AS IT PRESENT A SERIOUS EXPOSURE AND LIABILITY TO INJURE AND HARM THE TRAVELING PUBLIC. *TR
