2008 GMC ACADIA Complaints

DRIVING GMC ACADIA TO MY SONS BASEBALL GAME AND THE CAR JERKED FORWARD, SO I IMMEDIATELY SLOWED DOWN. CONTINUED TO DRIVE AND THE CAR BASICALLY WOULD NOT GET OUT OF 1ST GEAR. THE RPM'S KEPT GOING UP AND NEVER CAME DOWN AND THE CAR WOULD NOT GO OVER 40 MPH WHILE THE ENGINE WAS GEARING UP. THE TRANSMISSION WAS COMPLETELY SHOT. TOOK TO THE DEALERSHIP TO HAVE REPAIRED. GMC HAS TONS OF 2007 AND 2008 ACADIA'S WITH THE SAME PROBLEM AND ARE FORCING CUSTOMERS TO PAY FOR THE REPAIR. THE WAVE PLATE WAS SHOT ALONG WITH EVERYTHING ELSE IN THE TRANSMISSION. ON MY BILL THEY PUT N/C IN ALL THE PARTS AND LABOR AND THEN JUST PLUGGED IN AN AMOUNT IN A LINE ITEM CALLED " MISC CUSTOMER DEDUCTIBLE" NO ONE WILL EXPLAIN THE CHARGE. DEALERSHIP TOLD ME THE GMC CALCULATES THE CHARGE AND GMC TOLD ME TO CALL THE DEALERSHIP. THEY ARE GIVING PEOPLE A "DISCOUNT" OF SOME SORT SO THEY CLEARLY KNOW THEY HAVE AN ISSUE BUT THEY SHOULD BE FOOTING THE ENTIRE BILL. MY CAR IS 30,000 MILES UNDER THE WARRANTY AND 28 DAYS OVER THE 5 YEARS AND IT COST ME OVER $1,200 TO FIX IT WHEN THEY PUT IN A DEFECTIVE PART AND THEY KNOW IT. *TR

I WAS DRIVING 45PMH AND ALL OF A SUDDEN I DIDN'T SEEM TO HAVE POWER SO I PULLED OVER AND CALLED MY HUSBAND WHERE HE ASKED ME MY RPM AND IF I COULD MANUALLY SHIFT, ETC. I COULD MANUALLY SHIFT AND ONLY HAD 2ND GEAR. I CALLED AND HAD IT TOWED TO THE DEALER WHERE THEY CHARGED ME $4400 TO REPLACE THE TRANSMISSION DUE TO FAULTY WAVE PLATE. NO HELP FROM GM DUE TO OUT OF WARRANTY BECAUSE I'VE HAD IT OVER 5 YEARS. *LN

2008 GMC ACADIA SLT-2 WITH 42,300 MILES; NOT YET 6 YEARS OLD. "SERVICE STABILITY CONTROL" AND "SERVICE TRACTION CONTROL" WARNINGS RECEIVED PERIODICALLY. THIS WEEK, TRANSMISSION STARTED TO SHIFT UNEVENLY; NOT CORRECTLY UPSHIFTING/DOWNSHIFTING WHILE DRIVING AT 30MPH. CAR NOW ONLY OPERATES IN 1ST GEAR. NO HIGHER GEARS, NO REVERSE.....ENGINE JUST REVS. CAR HAS COMPLETE SERVICE REC NO LONGER SAFELY DRIVABLE. APPEARS TO BE PART OF THE KNOWN WAVEPLATE ISSUE. WHY NO RECALL WITH THE GREAT NUMBER OF SIMILAR ACADIAS WITH THE SAME PROBLEM OVER AND OVER? THANKS FOR YOUR ATTENTION. *TR

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

WHILE DRIVING, THE VEHICLE SUDDENLY LOST POWER AND WOULD NOT ACCELERATE. THE VEHICLE COULD ONLY BE DRIVEN 20 MPH. WHEN THE VEHICLE WAS TAKEN TO THE DEALER, THE CUSTOMER SERVICE MANAGER IMMEDIATELY DIAGNOSED THE PROBLEM AND SAID HE HAD RECENLY SEEN SEVERAL GMC ACADIA'S WITH THE SAME ISSUE. HE STATED THE PROBLEM IS THE WAVE PLATE INSIDE THE TRANSMISSION WHICH ARE FAULTY IN SEVERAL GENERATIONS OF GMC ACADIAS. HE FURTHER STATED THE WAVE PLATE COULD ONLY BE REPLACE WITH ANOTHER ONE THAT IS ALSO SUCCEPTABLE TO FAILURE. UPON REPAIR OF THE PROBLEM, THE DEALER CONFIRMED THE TRANSMISSION WAVE PLATE WAS CRACKED HOWEVER SAID THERE WAS NOTHING THEY COULD DO ABOUT IT. *JS

VEHICLE HAS A DELAYED SHIFT INTO 3RD AND 5TH GEAR, WITH A VIBRATION FELT IN THOSE GEARS. FOUND CODES P0717 P0716 FOR INPUT SPEED SENSOR ON TRANSMISSION. IT IS BELIEVED THE VEHICLE HAS A BROKEN 35R WAVE PLATE AND NEED TO TARE DOWN TO INSPECT OR REPLACE TRANSMISSION AT ONLY 63,000 MILES. EXTREMELY COMMON PROBLEM ON THESE VEHICLES (PLEASE REFER TO GMC ACADIA FORUMS ONLINE EVERYWHERE FOR OTHER VICTIMS). *JS

CHECK ENGINE LIGHT CAME ON. HAD ONSTAR DIAGNOSE IT AND IT CAME BACK AS TRANSMISSION CODES. THE TRANSMISSION SOLENOID IS CLOGGED UP, COULD BE FROM CONTAMINENENTS IN THE FLUID OR COULD BE MY CLUTCH WAVE PLATE IS COMING APART LIKE SO MANY OTHERS HAVE EXPERIENCED. OUT OF WARRANTY 5 MONTHS. CONTACTED GMC CUSTOMER CARE, THEY WERE NO HELP.

FOR SEVERAL WEEK I HAVE BEEN HAVING POWER STEERING PROBLEMS WITH THE GMC ACADIA. THIS PARTICULAR VEHICLE HAD A "NOISY" POWER STEERING SINCE NEW AND I BROUGHT THIS TO THE ATTENTION OF THE DEALER ON TWO OCCASIONS WHILE UNDER WARRANTY. THE SERIVCE PERSONAL SAID THAT GMC WAS AWARE OF ISSUES BUT THEY DID NOT HAVE A "FIX". THE VEHICLE IS EXTREMLY HARD TO TURN A LOW SPEED AS IF THE POWER STEER IS NOT FUNCTIONING. MY WIFE IS NOT ABLE TO DRIVE THE VEHICLE DUE TO THE STRENGTH REQUIRE TO TURN THE WHEEL AND I WILL NOT ALLOW HER TO DRIVE IT WITH OUR CHILDREN DUE TO SAFETY CONCERNS. THIS PAST WEEKEND I WENT OFF THE ROAD (OVER THE CURB) WHILE TURNING INTO A SUBDIVISION SINCE THE STEERING SEEMED TO "LOCK UP". I HAVE READ NUMEROUS REPORTS ON THE INTERNET OF THE EXACT SAME PROBLEM. THIS IS A KNOWN PROBLEM THAT GMA IS AWARE OF BUT HAS NOT OFFER ANY RECALL OR ASSISTANCE TO REPAIR THE POWER STEERING SYSTEM. THE COST OF REPAIR IS NEARLY $2000.00. I FEEL THAT GMC SHOULD BE REQUIRED TO FIX THIS ISSUES AS IT IS MAJOR SAFETY CONCERN.

WHILE ACCELERATING AT A LIGHT, THE TRANSMISSION STARTED TO JERK. WITHIN 5 MILES, COULD NOT DRIVE FASTER THAN 30 MPH. COULD NOT GET INTO REVERSE. APPEARS THAT THE TRANSMISSION IS TOTALLY SHOT. 57,000 MILES AND 5 YEARS 10 MONTHS.

TL* THE CONTACT OWNS A 2008 GMC ACADIA. THE CONTACT STATED THAT THE STEERING WHEEL FAILED AND BECAME HARD TURN WHEN PARKING OR WHEN TURNING AT LOW SPEEDS. THE FAILURE WAS EXPERIENCED NUMEROUS TIMES. THE VEHICLE WAS TAKEN TO THE DEALER, WHO FLUSHED THE POWER STEERING LINES. THE FAILURE WAS NOT CORRECTED. THE VEHICLE WAS TAKEN BACK TO THE DEALER FOR FURTHER INSPECTION. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 77,700 AND THE CURRENT MILEAGE WAS 104,000. UPDATED 11/19/13*LJ THE CONSUMER STATED THAT THE WAVE PLATE AND TIMING CHAIN WERE BOTH REPLACED UNDER WARRANTY. THE STEERING GEAR BOX PUMP WAS NOT COVERED UNDER WARRANTY. UPDATED 12/2/2013 *JS
