NHTSA Complaint #10545431 — 2008 GMC ACADIA

FIRST INCIDENT OCCURRED WHEN WE WENT TO A FAMILY REUNION FOR THE WEEKEND. WE WERE AT A CAMP GROUND IN A CABIN AND DID NOT ENTER THE CAR ALL WEEKEND. IT RAINED ALL WEEKEND VERY HARD AT TIMES. WHEN WE DID ENTER THE CAR TO GO HOME NOTED APPROX. 1 INCH OF WATER TO THE FLOOR OF BOTH DRIVER AND PASSENGER SIDE OF VEHICLE. AT THE TIME I THOUGHT MAYBE I JUST DIDN'T HAVE THE SUN ROOF CLOSED ALL THE WAY. DRIED IT UP AND DIDN'T THINK MUCH MORE ABOUT IT. CAR IS GARAGE KEPT SO MOST OF THE TIME IT IS NOT EXPOSED TO RAIN. ANOTHER DAY TOOK MY SON TO DENTIST, IT WAS RAINING VERY HARD THAT DAY ON THE WAY HOME WATER STARTED POURING OUT OF 3RD ROW LIGHT THEN NOTED SOUNDS OF WATER SPLASHING AROUND IN HEADLINER. I WAS ABLE TO DRY IT UP AND MENTIONED IT WHEN I HAD AN OIL CHANGE. I WAS TOLD THE DRAIN TUBES WERE PROBABLY BLOCKED AND DID A CHECK ON THOSE WITH NO PROBLEMS. AS I SAID THE CAR IS GARAGE KEPT SO FORTUNATELY IT HAS NOT BEEN EXPOSED TO A LOT OF RAIN. HOWEVER THIS WEEK WE HAVE HAD A LOT OF RAIN THE CAR HAS BEEN PARKED OUT SIDE WHILE I WORK. YESTERDAY WHEN I CAME HOME I AGAIN NOTED LARGE AMOUNT OF WATER IN FLOOR BOARDS. DRIED IT UP AGAIN WITH PLAN TO TAKE TO DEALER ON NEXT DAY OFF. TODAY WHEN I CAME HOME FROM WORK I HAD PLACED TOWEL IN SUNROOF AREA IN CASE OF MORE RAIN, TOWEL WAS SOAKED DRIPPING DOWN ONTO SEATS FLOOR WAS AGAIN SOAKED. WHEN I GOT HOME TURNED KEY OFF, REMOVED KEY BUT CAR CONTINUED TO RUN, SPUTTERED FOR APPROX. 2-3 MINS THEN SHUT OFF. STARTED IT UP AGAIN AND SHUT IT OFF REMOVED THE KEY AND IT DID THE SAME. HEARD A CONTINUED HUMMING SOUND COMING FROM ENGINE. AT THIS POINT I HAD WORKED ALL NIGHT SO JUST LEFT IT. I WILL TAKE TO DEALER TOMORROW BUT IT IS OUT OF WARRANTY. I HAVE RESEARCHED THIS PROBLEM AND FOUND HUNDREDS OF COMPLAINTS. NO FIX BY GMC. *JS
