WE WERE 50 MILES FROM HOME ON A VACATION WITH OUR TWIN 2 YEAR OLDS AND 7 YEAR OLD WHEN THE TRANSMISSION WENT OUT. FIRST IT SAID "TRANSMISSION HOT, LEAVE ENGINE ON IDLE". SO WE SAT FOR 10 MINUTES. IT WENT AWAY, THOUGHT WE WERE OK, KEPT DRIVING FOR ABOUT ANOTHER 15 MINUTES AND COMPLETE FAILURE. WE WERE STRANDED FOR 3 HOURS IN THE MIDDLE OF NOWHERE (DETOURED ROAD TOOK US BACK ROADS). COULDN'T GET A TOW. HUNGRY, HOT AND THIRSTY LITTLE BOYS. COPS GOT CALLED ON US BECAUSE WE ENDED UP BEING ON SOMEONE'S PROPERTY WE SHOULDN'T BE. TOTAL MESS. EMBRACED, HOT, IRRITATED AND SO ANGRY. $15,000 OWED ON A VEHICLE THAT WE HAVE TO REPLACE A $3600 TRANSMISSION! SERIOUSLY?!?! WHAT WOULD HAVE HAPPENED IF I WAS BY MYSELF AND MY HUSBAND WASN'T WITH ME. OR IT CAUSED A WRECK WITH ME AND MY CHILDREN IN THE CAR. GMC WON'T HELP BECAUSE WE ARE PASSED WARRANTY. APPARENTLY AFTER DOING RESEARCH THIS IS A COMMON PROBLEM. IF I FIX IT I'M STUCK WITH A CAR I DON'T TRUST AND OWE TOOOOO MUCH MONEY ON FOR WHAT IT'S WORTH AND OH GREAT PUT IN THE SAME [XXX] TRANSMISSION THAT FAILED THE FIRST TIME AND COULD HAPPEN AGAIN. WILL NEVER OWN ANOTHER GMC- RIDICULOUS AND NEEDS TO BE LOOKED INTO. THIS HAPPENS FAR TOO MUCH FOR THERE NOT TO BE A LAWSUIT OR RECALL ON THIS ITEM. ABSOLUTELY RIDICULOUS! PLUS OBVIOUSLY NO VACATION, OUR MONEY GOT TO GO INTO A CAR WE SHOULDN'T HAVE TO PUT THIS MUCH MONEY INTO. DISAPPOINTED ON SO MANY LEVELS.

2008
POWER TRAIN
MY WIFE WAS DRIVING HER 2008 GMC ACADIA ON THE FREEWAY WHEN THE TRANSMISSION SUDDENLY GAVE OUT AND SLIPPED OUT OF GEAR. THE VEHICLE WOULD NOT ACCELERATE. SHE WAS IN THE FAST LANE TRAVELING 70 MPH IN THE FAST LANE. SHE HAD TO FIGHT THROUGH TRAFFIC TO GET OVER TO THE SHOULDER SO SHE COULD PULL OFF THE FREEWAY ENOUGH TO AVOID GETTING HIT BY OTHER CARS TRAVELING THE FREEWAY. SHE THEN HAD TO EXIT THE VEHICLE WITH OUR CHILDREN DURING HIGH TRAFFIC TIME. VERY UNSAFE SITUATION FOR A VEHICLE WITH ONLY 69K MILES ON IT. THIS IS A KNOWN ISSUE WITH THE 2007 AND 2008 LAMBDA PLATFORM VEHICLES. GMC KNOWS ABOUT THE 3-5-R WAVE PLATE THAT WAS NOT HEAT TREATED DURING THE BUILDING OF THESE TRANSMISSIONS. SEARCH THE WEB OR EVEN FORUMS FOR 3-5-R WAVE PLATE FAILURE AND SEE WHAT COMES UP. I FEEL THEY SHOULD ATLEAST EXTEND THE WARRANTY IF NOT RECALL THIS TRANSMISSION BEFORE SOMEBODY GETS HURT OR KILLED WHEN ONE GOES OUT IN TRAFFIC. *TR
