2007 GMC ACADIA Power Train Problems

WHILE DRIVING AT APPROXIMATELY 25 MPH VEHICLE WAS SHIFTING VERY HARD. THE VEHICLE CONTINUED TO HAVE ISSUE SHIFTING. AT ANOTHER TIME WAS DRIVING VEHICLE AND STOPPED AT A TRAFFIC LIGHT. UPON LIGHT TURNING GREEN PUSHED ON THE ACCELERATOR AND THE VEHICLE WOULD NOT GO, TRANSMISSION WOULD NOT SHIFT INTO GEAR. VEHICLE HAS 83,000 MILES AND NOW THE TRANSMISSION NEEDS TO BE REPLACE. SEEMS TO BE A FREQUENT ISSUE WITH THIS VEHICLE MODEL. GM SHOULD RECALL THIS TRANSMISSION!! *TR

WE PURCHASED THIS ACADIA USED IN APRIL 2010 WITH ABOUT 40,000 MILES. IN EARLY JULY 2012 THE TRANSMISSION WENT OUT. THIS HAS BEEN REPAIRED UNDER OUR EXTENDED WARRANTY AS OF JULY 15, 2012. ON AUGUST 1, 2013, OUR TRANSMISSION WENT OUT AGAIN. DURING THE FIRST YEAR OF OWNING THIS VEHICLE, WE HAVE HAD THE WINDSHIELD WIPERS OPERATING ERRATICALLY AND THE RADIO WILL NOT ALWAYS SHUT OFF WHEN THE ENGINE HAS BEEN STOPPED AND DRIVER'S DOOR OPENED & CLOSED (POSSIBLE ELECTRICAL PROBLEMS). WE'VE ASKED OUR GMC DEALERSHIP TO ADDRESS THE ELECTRIC, BUT EACH TIME THEY SAY NOTHING SHOWS ANY ERRORS ON THEIR COMPUTER TESTS. WITH THE RECENT ISSUE IN A LITTLE OVER A YEAR ON THE TRANSMISSION (AGAIN!) WE HAVE FOUND NUMEROUS SITES FROM OTHER 2007 ACADIA OWNERS STATING THE SAME PROBLEMS AND THAT IT IS REPETITIVE. IF THIS HAS BEEN A WIDESPREAD AND KNOWN PROBLEM, THIS WAS NOT SHARED BY...

WHEN I PURCHASED THE VEHICLE THERE WAS A NOTICEABLE WHINE IN THE STEERING. I ASKED THE SALESMAN AND HE SAID THAT NOISE WAS TYPICAL WITH ACADIA'S AND THERE WAS NO ISSUE WITH THE CAR. WHEN I TOOK IT IN FOR AN OIL CHANGE AT A DIFFERENT DEALER RIGHT BEFORE WE LEFT ON VACATION, I WAS TOLD THE POWER STEERING PUMP WAS GOING OUT AND NEEDED TO BE REPLACED IMMEDIATELY. DID THAT EVEN THOUGH WE WERE DELAYED GOING ON VACATION AND SUBSEQUENTLY HAD IT REPLACED TWO MORE TIMES AS WELL. ALSO HAVE HAD LEAKS IN THE SUNROOF THAT CONTINUE TO RETURN, AND HAVE NOW MESSED UP MY POWER WINDOW CONTROLS TO THE POINT THAT I CAN NOT CONTROL ANY OF THE OTHER WINDOWS FROM THE DRIVERS SEAT. HAVE HAD TO REPLACE THE WATER PUMP, FRONT STRUTS, AND NOW THE SOLENOIDS ARE BEING REPLACED AS WELL. WHEN I PURCHASED MY CAR IT...

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...

AS I WAS TAKING A FAMILY TRIP, I WAS TRAVELING THROUGH SOME STEEPER GRADES WHEN THE VEHICLE RPMS WERE REGISTERING VERY HIGH AND WOULD NOT SHIFT TO LOWER GEARS EVEN WHEN MY TRAVEL SPEED SLOWED DOWN. ON MY DISPLAY A WARNING CAME ON SAYING TO IDLE THE VEHICLE TRANSMISSION HOT' I THEN PULLED OVER IN A VERY BUSY ROAD AND LET THE VEHICLE IDLE FOR 10 MIN IT THEN SHUT OFF BUT HAD VERY WEIRD DRIVING CHARACTERISTIC THE REST OF THE WAY. THIS INCLUDED WHEN SHIFTING FROM SECOND GEAR TO THIRD IT FELT LIKE THE CLUTCH WOULD POP AND JERK THE VEHICLE WHEN IT DID SHIFT. THANKFULLY AS WE GOT CLOSER TO A TOWN THE VEHICLE ENGINE LIGHT CAME ON AND WE IMMEDIATELY CONTACT ONSTAR AND THEY GAVE US THE CODES ALL RELATING TO THE VEHICLE WAVE PLATE FAILURE. I THEN HAD TO TAKE IT TO A DEALER OUT IN...

I PARKED MY CAR LAST NIGHT WITH NO SIGNS OF TRANSMISSION PROBLEMS. THIS MORNING I GET INTO TO GO TO WORK AND I NOTICE THAT THE VEHICLE WILL NOT SHIFT OUT OF FIRST GEAR. PROBLEM IS DIAGNOSED AND FOUND TO BE "TRANSMISSION SHIFT SOLENOID A". DEAL STATED THAT THEY ARE NOT AWARE OF ANY SUCH PROBLEMS WITH THIS MAKE AND MODEL. AFTER RESEARCHING ONLINE I DISCOVER MANY MANY OF THE SAME EXACT ISSUES WITH SAME MAKE AND MODEL. DEALER IS REQUIRING $3000.00 THE REPAIR. *TR

DRIVING HOME FROM THE BEACH WITH MY FRIEND, NO SERVICE LIGHTS WERE ON. WHILE DRIVING ON THE GARDEN STATE PARKWAY MY CAR WAS BECOMING SLUGGISH ON THE PICKUP WHILE CHANGING LANES. A COUPLE EXITS DOWN THE ROAD THE CHECK ENGINE LIGHT CAME ON ALONG WITH A MESSAGE - "TRANSMISSION HOT, IDLE ENGINE". I SAFELY PULLED THE CAR OVER 2 EXITS AWAY INTO THE RESTSTOP AND SHUT THE CAR OFF. I WAITED APPROXIMATELY 20-25 MINUTES AND RESTARTED THE CAR, ALL SERVICE LIGHTS WERE NOW GONE. ME AND MY FRIEND DECIDED TO NOW CAUTIOUSLY DRIVE THE CAR HOME SINCE ALL THE SERVICE WARNINGS HAD GONE AWAY. AS WE BEGAN TO PULL OUT OF THE RESTSTOP THE VEHICLE COULD NOT ACCELERATE I THEN WAS STUCK ON THE SIDE OF THE EXPRESS LANE ON THE PARKWAY. SINCE THIS INCIDENT I HAD THE VEHICLE CHECKED AND IT TURNS OUT MY ENTIRE TRANSMISSION IS BROKEN, NOT...

CAR SHUT DOWN WHILE I WAS DRIVING. AFTER AWHILE IT STARTED BACK UP BUT IT WOULD ONLY GO ON FIRST GEAR SO I COULD GO MORE THAN 20MPH. THEN WHEN I WENT HOME, THE CHECK ENGINE LIGHT CAME ON AND THE REVERSE DID NOT WORK. I HAVE READ ALOT OF COMPLAINTS ABOUT THE SAME PROBLEM WITH 2007 ACADIAS. I HOPE THESE CARS GET RECALLED BECAUSE SOME PEOPLE MIGHT NOT BE AS LUCKY AS I WAS WERE THERE WEREN'T ANY CARS AROUND OR IN THE INTERSTATE. *TR

STARTED THE VEHICLE THIS MORNING WITH REMOTE START, GOT IN AND PUSHED THE KEY FORWARD. AS I LEFT THE APARTMENT COMPLEX ON MY WAY TO THE POST OFFICE, I NOTICED MY ACADIA STARTED HAVING PROBLEMS SHIFTING PAST 20MPH. I TOOK IT TO A LOCAL TRANSMISSION SHOP AND WHEN THEY DRAINED THE FLUID, THE FLUID WAS BURNT REQUIRING THE TRANSMISSION TO BE OPENED UP. I HAVE STILL NOT HAD THE TRANSMISSION MANIPULATED PAST THE FLUID DRAINAGE. I EVEN TOOK VIDEO OF THE SPEEDOMETER AND RPM GAUGE WHILE IT WAS HAVING TROUBLE SHIFTING. *TR

VEHICLE IS HARD SHIFTING FROM 1ST TO 2ND GEAR. HAD SERVICED WITH NEW TRANSMISSION FLUID ON 7/2/13. ON 7/5/13 VEHICLE WOULD NO LONGER SHIFT AT ALL WHILE TRAVELING ON THE FREEWAY ON OUR WAY TO FAMILY VACATION TO HILTON HEAD SC. IT WAS TOWED TO PARKS CHEVROLET IN CHARLOTTE, NC WHERE TRANSMISSION WAS DISASSEMBLED WITH PARTS REPLACED AND REBUILT. UPON DEPARTURE OF PICKUP VEHICLE IS STILL SHIFTING HARD FROM 1ST TO 2ND GEAR (AROUND 20-25MPH) AND WE HOPE TO MAKE BACK HOME TO OHIO SAFELY. I'VE RESEARCHED THIS ISSUE IS COMMON IN GMC ACADIAS. ISSUES NEEDS ADDRESSED AND RESOLVED FOR SAFETY! I WILL BE RETURNING THE VEHICLE TO CHEVY DEALER WHEN WE RETURN HOME FOR FURTHER SERVICE. WE HAVE ALREADY PAID THE WARRANTY DEDUCTIBLE AND HOPE TO NOT INCUR MORE EXPENSES! *TR

THE CAR SUDDENLY LOST POWER ON THE INTERSTATE. IT LOCKED DOWN INTO "LIMP HOME" MODE. WE HAD CRAWL ALONG THE BERM AT 30 MPH. THE PROBLEM WAS DIAGNOSED BY GM AS TRANSMISSION FAILURE DUE TO FAILING OF THE WAVE PLATE. THIS WAVE PLATE IS A KNOWN PROBLEM TO GM BUT AS OF NOW NO RECALL HAS BEEN ISSUED. I HAVE READ ONLINE BLOGS ABOUT THIS ISSUE AND IT IS A FREQUENT AND UNSAFE FAILURE OF THIS DRIVE-TRAIN. OUR CAR IS OUT OF WARRANTY BY YEARS BUT ONLY HAS 84K MILES ON IT. GM HAS OFFERED US A 50/50 SPLIT ON THE REPAIR WHICH THEY WOULD NEVER DO IF THEY WERE NOT AWARE OF THIS ISSUE. I THINK IT SHOULD BE THEIR FULL RESPONSIBILITY. PLEASE INVESTIGATE, THANK YOU. *TR

DRIVING UP HILL, LOOSING POWER, FINALLY MADE IT UP HILL CAR JUST STOPPED - ALMOST LIKE IT WAS IN NEUTRAL GEAR. COULDN'T GO ANYWHERE, CAR STARTED RIGHT UP AND WHEN I PRESSED ON GAS IT REVVED UP LIKE IT WANTED TO GO, BUT NO MOVEMENT. STILL LIKE IN NEUTRAL GEAR. FOUND OUT THAT LOTS OF 07 AND 08 ACADIA OWNERS HAVE HAD ISSUES WITH THE WAVE PLATE (WHICH IS WHAT MECHANIC AT DEALERSHIP TOLD ME IT IS). AND THE POWER TRAIN, WHICH ENDS UP MAKING THE TRANSMISSION FAIL. THERE ARE FAR TOO MANY ACADIAS OWNERS OUT THERE WHO HAVE HAD THESE ISSUES. I THINK IT'S WRONG THAT GMC DOESN'T INVESTIGATE OR RECALL THE CARS FOR THIS COST. I CALLED GMC CUSTOMER SERVICE AND FEEL AS IF THEY DON'T TRULY CARE, THEY JUST WANT TO SNUB OFF THE ISSUE AND TELL YOU TO HAVE A GREAT DAY! MY DAD WORKED FOR...

THIS ISSUE STARTED WHEN I WAS DRIVING DOWN THE ROAD AT 35MPG. THE ACADIA TRIED TO SHIFT INTO A HIGHER GEAR BUT CLUNKED VERY LOUDLY AND JOLTED THE WHOLE CAR. FROM THAT POINT FORWARD THE VEHICLE WAS STICK IN 3RD GEAR. IT WOULDN'T UP SHIFT OR DOWN SHIFT. THE CAR LIMPED HOME BUT STARTING ON HILLS OR AT STOP SIGNS WAS ALMOST IMPOSSIBLE. ONCE I GOT THE CAR HOME I CHECKED THE TRANSMISSION FLUID. TRANSMISSION FLUID OK. I THEN TESTED THE CAR AGAIN BY TRYING TO BACK OUT OF THE DRIVEWAY. THE TRANSMISSION MADE A LOUD GRINDING NOISE AND WOULD NOW LONGER MOVE IN REVERSE. I HAD THE CAR TOWED FROM MY HOUSE TO A LOCAL TRUSTED MECHANIC. THE MECHANIC STATED THAT THE WAVEPLATE FAILED. HE ALSO SAID THAT THIS WAS A KNOW DEFICIENCY IN THESE VEHICLES AND THAT THE TRANSMISSION WOULD NEED TO BE REPLACED OR REBUILT. I HAD...

POWERTRAIN (TRANSMISSION) GAVE - OUT AT 72100 MILES ON MY 2007 GMC ACADIA AND GMC DEALER STATING "MOVE PLATE" AND "CONTROLLED MODULE" AND ESTIMATES ARE AT $4000.00. I HAVE READ MANY COMPLAINTS ONLINE ABOUT THIS ISSUE AND IT SHOULD BE MENTION ON NHTSA AND HAVE GMC MAKE A RECALL. *TR

TL* THE CONTACT OWNS A 2007 GMC ACADIA. THE CONTACT STATED THAT THE VEHICLE WOULD HESITATE TO ACCELERATE AND OPERATE SLUGGISHLY. THE TIMING CHAIN WAS REPLACED BY THE DEALER HOWEVER, THE FAILURE LATE RECURRED WITH THE ILLUMINATION OF THE CHECK ENGINE WARNING LIGHT. AN ENGINE FLUSH WAS PERFORMED ON THE VEHICLE AND THE FAILURE SUBSIDED FOR THREE WEEKS BEFORE RECURRING. THE VEHICLE WAS TAKEN BACK TO THE DEALER, WHO ADVISED THAT THERE WAS A SEIZED SOLENOID IN THE TRANSMISSION, WHICH WOULD REQUIRE REPLACING. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 120,000 AND THE CURRENT MILEAGE WAS 130,000. *TR

WHILE AN HOUR FROM HOME, I WAS DRIVING THROUGH A TOWN AND SUDDENLY COULD GET NO "PICKUP" TO START AFTER STOPPING AT A STOPLIGHT. I WAS JUST SITTING THERE IN THE INTERSECTION WHILE TRAFFIC DROVE AROUND ME. I CONTINUED TO MY DESTINATION THIS WAY, BARELY ABLE TO GET GOING AFTER STOPPING. THEN WHEN COMING HOME I HAD "PICKUP" BUT THE VEHICLE WAS SHIFTING IMPROPERLY. I TOOK IT TO THE DEALER AND THEY DIAGNOSED A BROKEN WAVE PLATE AND SAID IT NEEDED A NEW TRANSMISSION. AFTER READING ABOUT ALL THE OTHER ACADIA OWNERS WHO ARE ALSO HAVING THIS PROBLEM, I BELIEVE THE PROBLEM NEEDS TO BE ADDRESSED BY GMC. I DROVE MY CAR AFTER I WAS TOLD IT NEEDED A NEW TRANSMISSION, AND THE TRANSMISSION FAILED IN A BIG WAY WHILE I WAS DRIVING DOWN THE ROAD. SUDDENLY I WAS PUSHING THE GAS PEDAL, BUT NOTHING WAS HAPPENING - MY VEHICLE...

NO PRIOR PROBLEMS, NO WARNINGS. WE PULLED UP TO A STOP SIGN, CAME TO A STOP AND THEN PROCEEDED THROUGH THE INTERSECTION WHEN THE TRANSMISSION FAILED. WE WERE LEFT STALLED IN FRONT OF ONCOMING TRAFFIC. I HAD MYSELF AND 5 PASSENGERS INCLUDING FOUR CHILDREN AGES 10 AND UNDER. IF THE TRAFFIC HAD NOT STOPPED WE ALL COULD HAVE SUFFERED MAJOR INJURIES. THERE WAS NO REASON PRIOR TO THE FAILURE TO SUSPECT THAT THERE WE ANY PROBLEMS. NO ENGINE WARNING LIGHTS OR ANYTHING. *TR

DRIVING DOWN THE HIGHWAY THE TRANSMISSION FAILED. TURNS OUT THE 2007-2009 MODELS HAVE A KNOWN ISSUE OF A FAILED "WAVE PLATE". MY SON AND I WERE ALMOST IN AN ACCIDENT BECAUSE OF THIS. THE VEHICLE WAS TOWED TO THE GMC DEALER. *TR

ON 1/25/13 OUR 2007 GMC ACADIA WAS TOWED TO THE SHOW FOR WHAT WAS DESCRIBED AS A TIMING CHAIN PREMATURE WARE AND WAS COVERED UNDER A RECALL. THE MILEAGE ON THAT DATE WAS 52,788. IT IS OUR UNDERSTANDING THAT THE MOTOR AND TRANSMISSION HAD TO BE REMOVED. ON MAY 18TH 2013 I WAS DRIVING AND THE CAR MADE A LOUD NOISE AND DECELERATED DOWN TO 25 MPH WITH A HIGH RPM. AT THAT POINT I PULLED OVER. I NOTICED THE CAR HAD NO REVERSE. I BROUGHT THE CAR TO THE LOCAL GM DEALER. TODAY THEY CALLED AND SAID THE TRANSMISSION IS SHOT. CURRENT MILEAGE 55,308. WAITING TO HEAR BACK ON EXACT ISSUE. AFTER READING ONLINE THIS IS A KNOW DESIGN FLAW AND HAS BEEN SINCE CORRECTED. I SHOULD NOT HAVE TO PAY FOR GM'S DESIGN FLAWS. ALSO THIS IS A MAJOR SAFETY ISSUE WHEN YOUR VEHICLE SLOWS TO A MAXIMUM...

THERE IS A PROBLEM WITH THE TRANSMISSION ON THESE VEHICLES. I WAS TOLD SO BY THE TECHNICIAN THAT REPLACED MINE. OUR TRANSMISSION GAVE OUT AND LEFT MY WIFE AND CHILD STRANDED ON THE SIDE OF THE ROAD. THE TECH WHO WORKED ON MY VEHICLE SAID THAT THE WAVE PLATE IN THIS TRANSMISSION BLOWS APART. THE ONES THAT ARE BEING ISSUED TO REBUILD ARE BETTER. IF THERE IS AN ISSUE WITH THESE TRANSMISSIONS LEAVING PEOPLE ON THE SIDE OF THE ROAD WHY HASN'T THERE BEEN A RECALL? *TR

1-HEATED WASHER REMOVED, CATALYST CONVERTER REPLACED, TIMING CHAIN ISSUE, FUEL PUMP, HEAD LIGHTS ALL REPLACE DUE TO DEFECT AND NOW @ 89,500 I HAVE A MAJOR TRANSMISSION ISSUE A PO752 CODE HAS BEEN NOTED AND THE CAR IS 5.5 YEARS OLD AND BELIEVE THIS IS A DEFECT GMC IS AWARE OF AND FAILED TO FIX, EVEN SUGGGESTED BY AMAACO THE TCM MAY EVEN NEED REPLACING. FEEL LIKE THIS CAR HAS BEEN ONE DEFECT AFTER ANOTHER WHICH LED TO OTHER DEFECTS HAPPENING AND PREMATURE WEAR AND TEAR ON OTHER PARTS. *TR

TRANSMISSION FAILURE DUE TO FAULTY FACTORY ISSUED WAVE PLATE. THIS SHOULD HAVE BEEN A RECALL AS GM APPEARS TO BE VERY AWARE OF THIS PROBLEM IN MOST EARLY YEAR MODEL ACADIAS. THE PRICE TAG ALONE IS $4,000+... NOT TO MENTION A RENTAL CAR AND MAKING PAYMENTS ON AN UNDRIVABLE VEHICLE WHILE IT SITS FOR WHO KNOWS HOW LONG SINCE THE TRANSMISSION IS ON NATIONAL BACK ORDER BECAUSE ITS SUCH A COMMON PROBLEM. *TR

NO SPEED ENTERING THE FREEWAY AND THEN REVERSE SHOT THE CAR FORWARD INTO A FRONT YARD AND ALMOST INTO A HOUSE. I ENTERED THE FREEWAY AFTER PICKING MY 4 YEAR OLD UP FROM PRE-SCHOOL WITH MY 1 YEAR OLD ALSO IN THE CAR. THE CAR WOULD NOT GAIN SPEED AND RPMS SPIKING. NEARLY GOT IN AN ACCIDENT MERGING ONTO THE FREEWAY, EXITED FIRST OFFRAMP, PULLED INTO NEIGHBORHOOD AND TURNED INTO DRIVEWAY TO DO A THREE POINT TURN TO PARK ON THE SIDE OF STREET. PUT THE CAR IN REVERSE LIGHTLY TAPPED THE PEDAL, AND INSTEAD IT SPED FORWARD AS THOUGH THE GAS PEDAL WAS PINNED TO THE FLOOR. WE WENT DEEP INTO THE FRONT YARD OF HOUSE STOPPING JUST SHORT OF THE HOUSE. AAA CAME AND TOWED THE CAR TO THE CLOSEST GM DEALER. AAA DRIVER TESTED REVERSE AND IT WOULD ONLY GO FORWARD. HE SAID HE HAD NEVER SEEN...

ON THIS PARTICULAR DAY I WAS MERGING ON TO THE FREEWAY (WHICH SPEEDS OF OTHER TRAFFIC WAS UPWARDS OF 65 MPH). I ATTEMPTED TO ACCELERATE AND IN DOING SO WAS UNABLE TO SWITCH GEARS. THE VEHICLE "BOGGED DOWN" AND NEARLY CAUSED AN ACCIDENT AS I WASN'T GAINING SPEED. THIS ISSUE REPEATEDLY HAPPENED ON MY WAY HOME, TRAVELING A DISTANCE OF 60 MILES. THIS MALFUNCTION ACCORDING TO SOME DISCUSSIONS ON EDMUNDS IS WELL KNOWN BY GM! IT NEEDS TO BE MORE THAN FIXED, THE TRANSMISSIONS NEED REPLACEMENT. A BANDAID ISN'T GOING TO WORK IN THIS CASE. *TR

WE BOUGHT THIS CAR USED. HAD IT FOR LESS THAN A YEAR AND ONLY PUT 8,000 MILES ON IT. ON A RETURN BUSINESS TRIP THE TRANSMISSION WENT OUT WHILE GOING DOWN THE INTERSTATE. HAD TO CALL FOR A TOW AND HAVE HAD THE WORST EXPERIENCES WITH THE DEALERSHIPS WORKING ON IT. I'M ABSOLUTELY OVER THIS GMC AND THE JUNKY CAR THEY CREATED IN THE ACADIA. *TR

CAR WILL NOT ACCELERATE, ENGINE JUST REVS AND RPMS INCREASE TO 5000+ WHEN ATTAMPTING TO CHANGE FROM THIRD TO FOURTH GEAR. THANKFULLY, I WAS ON A ROAD LESS TRAVELED AND DID NOT GET SMASHED IN THE BACK WITH MY SON IN THE BACK SEAT ON THE HIGHWAY. WHAT A SAFETY HAZARD! *TR

WOULD NOT GO INTO REVERSE, WOULD NOT EXCEED 20 MPH IN DRIVE, RPM'S SPIKED TO 4000, CHECK ENGINE LIGHT COMES ON, ERRATIC DRIVING BECAUSE OF THE CONDITION, WEB SEARCH REVEALS NUMEROUS INCIDENTS OF SAME TYPE INVOLVING BREAKING WAVE PLATE FAILURE. *TR

THE TRANSMISSION ON OUR '07 ACADIA WENT OUT AFTER ONLY 67,000 MILES. WE HAD TO PAY OVER $3,000 OUT OF OUR OWN POCKETS TO GET IT REPAIRED BECAUSE IT WAS OVER THE FIVE YEAR WARRANTY PERIOD EVEN THOUGH IT WAS STILL WELL UNDER THE MILEAGE LIMIT. WHEN YOU PAY OVER $30,000 FOR A VEHICLE YOU EXPECT IT TO LAST LONGER THAN OURS DID WITHOUT HAVING TO PAY THOUSANDS MORE TO KEEP IT OPERATIONAL. A FEW MONTHS AFTER GETTING THE DRIVE TRAIN REPAIRED WE ARE EXPERIENCING CAMSHAFT/CRANKSHAFT ISSUES. THE VEHICLE IS FUNCTIONING AT ABOUT 60% OF ITS ORIGINAL POWER. WE CAN ONLY ASSUME THAT THIS WILL ENTAIL ANOTHER COSTLY REPAIR. *TR

ENGINE LIGHT ON VEHICLE, THE VEHICLE WILL NOT SHIFT INTO GEAR - HAPPENED THREE TIMES HAD TO PULL OFF SIDE OF ROAD TO NOT GET HIT FROM OTHER VEHICLES AND 5 YEAR OLD WAS ALSO IN CAR WITH ME. HAD TO SHUT OFF THE CAR MULTIPLE TIMES TO GET STARTED AGAIN AND FOR IT TO FINALLY SHIFT INTO GEARS. TOOK CAR TO DEALER AND THEY REPLACED TRANSMISSION CONTROL MODULE VALVE. ON 4/1/13 CAR WOULD NOT GO INTO REVERSE ON INCLINE. HAD TO DRIVE FORWARD AND REVERSE ON FLAT AREA, DEALER NOW SAYS THEY FOUND BROKEN WAVE PLATE AND BURNED 3-5 REVERSE CLUTCH. ALSO FOUND INTERNAL DEFECT PARK OF VALVE BODY. CAR IS ONLY 5 YEARS OLD AND HAS ONLY 55 THOUSAND MILES ON IT. SAW OTHER ISSUES ON THIS DATABASE ALL WITH BROKEN WAVE PLATES ON 07 ACADIAS. PAID THOUSANDS OF DOLLARS TO GET THIS FIXED. *TR

TL* THE CONTACT OWNS A 2007 GMC ACADIA. THE CONTACT STATED THAT THE VEHICLE WOULD NOT ACCELERATE OVER 40 MPH. IN ADDITION, THE GEAR SHIFTER COULD NOT BE MOVED INTO REVERSE. THE CHECK ENGINE WARNING LIGHT WAS ALSO ILLUMINATED. THE VEHICLE WAS TAKEN TO DEALER FOR INSPECTION AND THE CONTACT WAS ADVISED THAT THE TRANSMISSION NEEDED TO BE REPLACED. THE TRANSMISSION WAS REPLACED. THE MANUFACTURER WAS NOT MADE AWARE OF FAILURE. THE FAILURE AND CURRENT MILEAGE WAS 87,400.

AFTER SPENDING $370.51 AT MY LOCAL GMC DEALER FOR STABILITRAK ERRORS RESULTING IN LOW FUEL INPUT INTO THE ENGINE, WITH A MAXIMUM SPEED ALLOWABLE AT 35 MPH, MY 2007 GMC ACADIA IS ONCE AGAIN EXPERIENCING STABILITRAK ERRORS. THEY GENERALLY OCCUR WHEN I ROLL TO A STOP AT A STOPSIGN OR STOPLIGHT, BUT I AM VERY CONCERNED THAT THE TRANSMISSION WILL REDUCE SPEED WHEN I TRAVEL THE INTERSTATE. MY LOCAL GMC DEALER CLAIMED THIS PROBLEM WAS CAUSED BY A "CAM EXHAUST POSITION SENSOR FAULT" AND REPLACED THE "CAM EXHAUST POSITION SENSOR" ON 3-20-13 FOR $370.51. FOR ONE WEEK THIS REPAIR WORKED AND THERE WERE NO STABILITRAK ERRORS. TEN DAYS LATER, MY 2007 GMC ACADIA FWD IS WORSE THAN EVER, ENDANGERING ME AT NIGHT BY SHIFTING SUDDENLY INTO "STABILITRAK ERROR, LOW FUEL INPUT" MODE. I AM TERRIFIED THAT MY GMC DEALER WILL CHARGE ME MORE MONEY TO PRETEND-FIX THIS PROBLEM, AS THEY...

NO PREVIOUS SYMPTOMS. COULD NOT GET THE VEHICLE TO GO IN REVERSE. GOT TOWED TO THE DEALER. DIAGNOSIS - WAVE PLATE FRACTURE. FOUND MANY MANY 2007 GMC ACADIA'S HAD THIS PROBLEM, THERE SHOULD HAVE BEEN A RECALL. THIS HAPPENED 1 YEAR AFTER THE WARRANTY EXPIRED, BUT ONLY 74419 MILES, AND NEVER DRIVEN IN EXTREME CONDITIONS AND NEVER TOWED. *TR

NO RECALL FOR DEFECTIVE TRANSMISSIONS? BOUGHT 2007 ACADIAR USED, 2600 MILES /FELT TRANSMISSION PROBLEMS EARLY ON. VERY NOTICEABLE JERK AT 40MPH. IN AND OUT OF DEALERSHIP SINCE. LAST FEW MONTHS CAR HAS BEEN IN TO DEALER FREQUENTLY RE CAR BUCKING AT STOP LIGHTS REALLY ROUGH THOUGHT ENGINE GOING TO DIE. EVERY TIME NOTHING SHOWED IN CODES, EMERGENCY TRIP TO DOCTOR/HEAVY TRAFFIC MAIN ARTERY/CAN'T GET OVER 20MPH/ENGINE SCREAMING/ MAKE IT TO DR. (OMG) TOWED TO DEALERSHIP. TRANSMISSION GONE. I COULD HAVE HAD A SERIOUS ACCIDENT. FINALLY HEARD SOMETHING ABOUT A WAVE PLATE. FOR 5 YRS I'VE SAID SOMETHING WRONG. NO ONE SAID THESE WERE CONSTANT PROBLEMS WITH ACADIAS. THEY ISSUED RECALLS FOR A LEAK IN THE SUN ROOF. NO RECALL FOR DEFECTIVE TRANSMISSIONS? KNOWN DEFECTIVE WAVE PLATES? I HAVE EXTENDED WARRANTY, BUT MANY DON'T. WARRANTY OR NOT, THIS SAFETY HAZARD SHOULD BE FIXED BY GMC AT THEIR EXPENSE. A RECALL IS...

I WAS DRIVING MY CAR WHEN ALL OF A SUDDEN IT WOULDN'T ACCELERATE ABOVE (20MPH?). I WAS FORCED TO PARK IT AT AN APARTMENT COMPLEX AND GET IT TOWED TO THE DEALER. NOW LESS THAN 6 MONTHS AFTER PAYING OUT OF POCKET FOR THAT REPAIR, I AM HAVING THE SAME PROBLEM. *TR

STARTED SHIFTING WEIRD, THEN RPM'S WOULD SPIKE AS CAR WAS SHIFTING. CAR THEN WOULD NOT GO INTO ANY GEAR AND LEFT STRANDED ON SIDE OF ROAD. HAD TO HAVE VEHICLE TOWED TO DEALERSHIP WHERE IT WAS FOUND TO HAVE A BROKEN WAVE PLATE, DAMAGING NUMEROUS GEARS AND TORQUE CONVERTER. PRESSURE CONTROL MODULE WHICH IS PART OF THE VALVE BODY WAS BAD. HAD TO REPLACE ENTIRE TRANSMISSION, ALL SEALS, GASKETS. ALSO FOUND OUT WHEN REPLACING THAT THE THERMOSTAT HOUSING WAS LEAKING COOLANT, SO HAD TO HAVE THAT REPLACED AT SAME TIME. THIS AT A COST TO US OF OVER $3500.00. HAVE READ ONLINE THAT THIS IS A VERY COMMON ISSUE WITH THIS VEHICLE. WE WERE 7 MONTHS OUT OF OUR 5 YEAR/100,000 MILE WARRANTY AND GM WOULD NOT HELP IN THE LEAST. *TR

I HAVE OWNED THIS CAR FOR ABOUT A YEAR AND SINCE I HAVE OWNED IT HAVE HAD NOTHING BUT PROBLEMS. FIRST THE STRUTS WERE BLOWN, THE DASH LIGHTS WOULD GO FROM BRIGHT TO DIM, THE STEERING WHEEL MADE A CLICKING NOISE, THE WINDOWS LEAK...THIS CAR ONLY HAS 41,000 MILES I MEAN COME ON! NOW THE TRANSMISSION HAS COMPLETELY FAILED AND AFTER READING OTHER WEBSITES IT SOUNDS LIKE I WILL BE PAYING $4,000 DOLLARS. I AM A NEW MOM AND HAVE 3 STEP KIDS. I CAN'T FEEL SAFE IN MY CAR BECAUSE I'M WORRIED ABOUT IT BREAKING DOWN CONSTANTLY. NOW I HAVE TO DUMP ALL THIS MONEY THAT I DON'T HAVE INTO IT. I REALLY JUST WANT TO CUT MY LOSSES, BUT IS THAT REALLY THE BEST THING TO DO? I'M STUCK WITH THIS JUNKER CAR AND I COULDN'T FEEL MORE SORRY FOR ALL THESE OTHER PEOPLE HAVING THE SAME ISSUES....

VEHICLE HAS ABOUT 50,000 MILES BUT A FEW MONTHS OUT OF WARRANTY AND STARTED GIVING ME PROBLEM SHIFTING GEAR. RESEARCHED THE PROBLEM AND FOUND A LOT OF SIMILAR COMPLAINTS OUT THERE BUT GM IS REFUSING TO TAKE RESPONSIBILITY AND MAKING OWNERS PAY TO FIX THE PROBLEM. TRANSMISSION IS DEFECTIVE. *TR

2007 GMC ACADIA. CONSUMER WRITES IN REGARDS TO PROBLEMS WITH THE VEHICLE HEADLIGHTS AND THE TRANSMISSION. *SMD THE CONSUMER STATED ON DECEMBER 17, 2011, THE LEFT HEADLIGHT BURNED UP FOR NO APPARENT REASON. THE LOCAL DEALER QUOTED HIM $1,213.59. HE WAS ABLE TO GET THE HEADLIGHT FIXED FOR$ 695.67. ON DECEMBER 2, 2012 THE TRANSMISSION FAILED. THE CONSUMER HAD A REBUILT TRANSMISSION INSTALLED AT A COST OF $ 3,737.25.

3 MONTHS PAST THE 5 YEAR 100K WARRANTY WITH ONLY 55000 MILES ON THE CAR AND BOTH THE WATER PUMP AND TRANSMISSION WENT OUT. GM PAID FOR HALF OF THE COSTS STILL 1253.05 OUT OF POCKET WHEN IT SHOULD ALL HAVE BEEN COVERED. THIS IS A CONSISTENT PROBLEM WITH THE ACADIA AND GM KNOWS IT BUT REFUSES TO STEP UP. THE DAY THE TRANSMISSION WENT OUT WE ALMOST GOT THROWN THROUGH THE WINDSHIELD DEFINITELY A SAFETY ISSUE. *TR

PRIOR TO HAVING THE TRANSMISSION BREAK DOWN THE VEHICLE HAD BEEN SHIFTING HARD FROM 2ND GEAR TO 3RD GEAR. STARTING UP A SMALL GRADE FROM A STAND STILL THE TRANSMISSION SUDDENLY BEGAN SLIPPING AT ABOUT 20MPH. THE VEHICLE WOULD NOT SHIFT AND THE ENGINE LIGHT CAME ON. I WAS ONLY ABOUT 1 MILE FROM HOME SO I DROVE IT HOME AT ABOUT 25MPH. AT HOME I PUT IT IN REVERSE AND IT WOULD NOT GO INTO REVERSE. TOOK IT TO A TRANSMISSION SHOP THE NEXT DAY, THEY CALLED ME BACK LATER THAT DAY AND TOLD ME IT NEEDED A NEW TRANSMISSION. THEY ARE DOING THE JOB FOR $3200. *TR

I BOUGHT THIS VEHICLE JUNE 2012. I STARTED HAVING TRANSMISSION PROBLEMS LAST WEEK. THE TRANSMISSION WOULD STICK WHEN STEPPING ON THE GAS OR WHEN GOING IN REVERSE INTO MY GARAGE. I FOUND OVER 200 COMPLAINTS ABOUT THE TRANSMISSION. THIS SHOULD BE A RECALL ITEM. I WAS DRIVING ON THE HIGHWAY TRYING TO GET UP A HILL WHEN THE CAR STARTED TO DO THIS. I LUCKILY WAS NOT FAR FROM MY EXIT AND MADE IT TO A GAS STATION WHEN THE CAR JUST STOPPED. *TR

THE VEHICLE WOULD NOT SHIFT OUT OF 2ND GEAR GOING DOWN THE HIGHWAY. THE CHECK ENGINE LIGHT CAME ON, AND THERE ARE NOW FOUR CODES ALL FOR INTERNAL TRANSMISSION ISSUES. THE CAR IS 4 MONTHS PAST THE 5 YEAR WARRANTY, BUT ONLY 64000 MILES. THIS IS A HUGE SAFETY ISSUE. IF THIS TRANSMISSION FAILS WHILE ON AN INTERSTATE HIGHWAY, AND IT WILL NOT GO OVER 20 MPH, THE RESULTS COULD BE DEADLY. BY RESEARCHING THIS ISSUE I HAVE FOUND A CONSIDERABLE AMOUNT OF COMPLAINTS ABOUT 2007 GMC ACADIAS BETWEEN 50000 AND 80000 MILES HAVING TRANSMISSION FAILURES, BUT YET NO RECALLS. THIS IS AN ISSUE THAT GMC IS WELL AWARE OF, THROUGH THEIR OWN ADMISSIONS. WHY IS THERE SUCH A DELAY WAITING FOR A RECALL? ARE ALL OF THE COMPLAINTS GOING TO HAVE TO WAIT FOR A FATALITY BEFORE GMC ADMITS THERE NEEDS TO BE CORRECTIVE ACTIONS? *TR

THE CAR HAS HAD ELECTRICAL AND ENGINE PROBLEMS SINCE WE PURCHASED IT DUE TO WATER LEAKS FROM A FLAWED SUNROOF DESIGN. EVEN AFTER A RECALL TO FIX THE SUNROOF TO PREVENT WATER LEAKS; IT CONTINUES TO LEAK AND DAMAGE ELECTRICAL AND ENGINE SYSTEMS. THIS IS AN ONGOING PROBLEM AND IS A WIDESPREAD CONCERN FOR THE 2007-2008 GMC ACADIAS. I WOULD LIKE SOMEONE TO INVESTIGATE THIS PROBLEM. I BELIEVE IT IS A SAFETY CONCERN BECAUSE THE LEAKS OCCUR IN THE AREA WHERE THERE ARE AIRBAGS. I THINK THERE IS A STRUCTURAL DEFECT THAT MAY NOT BE ABLE TO BE REPAIRED AND IT PRESENTS A SAFETY HAZARD FOR ALL WHO DRIVE THESE VEHICLES. PLEASE INVESTIGATE THIS PROBLEM. DO NOT LET GMC SWEEP THIS UNDER THE RUG! *TR

WHILE TRAVELING AT 45 MPH, AND WITH NO WARNING (WEIRD SHIFTING, ETC) THE TRANSMISSION COMPLETELY FAILED. AFTER BEING LIED TO BY THE DEALERSHIP AND GM, I DID MY OWN RESEARCH AND FOUND THAT THIS IS A COMMON PROBLEM WITH THIS MODEL YEAR, SO MUCH SO THAT GM HAS CREATED A SPECIAL PROGRAM TO FUND PART OF THE REPAIR IF THE VEHICLE IS OUT OF WARRANTY. (WAVE PLATE FAILURE IN THE TRANSMISSION). THIS VEHICLE SHOULD BE RECALLED WITH A MANDATORY REPLACEMENT OF THE WAVE PLATE. *TR

MY 2007 GMC ACADIA'S FIRST STARTED HAVING TRANSMISSION PROBLEMS IN DECEMBER OF 2012. THE VEHICLE STARTED HAVING ISSUES WHILE TRYING TO MERGE ONTO THE HIGHWAY OR DEPRESSING THE GAS PEDAL FOR A PASSING AND/OR MERGING PURPOSES, THIS WOULD SOMEHOW REVERT INTO A NEUTRAL POSITION, HAVING THE RPMS REV UP AND NO FORWARD MOTION , UNTIL IT'S SORT OF CAUGHT UP ITSELF BY BACKING OFF ON THE ACCELERATOR. THE OTHER ISSUE INVOLVED PUTTING THE AUTOMOBILE INTO REVERSE ,NOT ONLY AT TIMES IT WOULDN'T GO INTO REVERSE BUT INSTEAD WOULD REVERT TO A NEUTRAL POSITION, UNTIL YOU STARTED ALL OVER AGAIN WITH THE PROCESS OF PUTTING IT BACK INTO PARK AND THEN BACK INTO REVERSE. NEVER WAS THERE A LIGHT NOR A WARNING BY THE CARS SENSORS OR ANY OTHER SYMPTOMS THAT WOULD GIVE AN OWNER A WARNING THAT THERE WOULD BE A PROBLEM COMING SOON. IN ANY EVENT, AFTER HAVING THE...

TL* THE CONTACT OWNS A 2007 GMC ACADIA. THE CONTACT STATED THAT WHILE DRIVING 40 MPH, THE TRANSMISSION FAILED AND THE VEHICLE WOULD NOT ACCELERATE ANY FURTHER. THE VEHICLE WAS TOWED TO THE DEALER FOR INSPECTION WHERE THEY STATED THAT THE TRANSMISSION NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED BUT PROVIDED NO ASSISTANCE .THE FAILURE MILEAGE WAS 73,000.

I HAVE A 2007 GMC ACADIA THE TRANSMISSION IS SLIPPING. THE DEALER TOLD ME IS A VALVE BODY INSIDE TRANSMISSION, NEED TO REPLACED WHOLE TRANSMISSION DON'T HAVE WARRANTY SO THE AMOUNT IS 2600.00 JUST THE TRANSMISSION NO LABOR. NOW I WAS READING AND THERE'S MANY CASES LIKE THIS THEY ARE SAYING THE PARTS THEY USED TO BUILD TRANS ARE MADE IN CHINA THAT'S WHY THERE SLIPPING AND HAVING TROUBLE WITH IT. NEED U GUYS TO CHECK ON THIS POWER TRAIN PROBLEM BEFORE SOME ONE GETS HURT WHILE DRIVING IT IS DANGEROUS. MY WIFE WAS DRIVING WITH MY BOYS INSIDE EVERY SINGLE ONE OF THEM GOT SCARED AND SAY THAT THEY DON'T LIKE THIS TRUCK NO MORE THANK YOU. *TR

WE WERE LEAVING MY SONS BASKETBALL GAME TONIGHT AND WHEN WE WENT TO ENTER THE INTERSTATE THE TACHOMETER WENT TO 5000 RPM'S AND THE VEHICLE WAS NOT MOVING. AS I AM SETTING ALONG THE INTERSTATE WITH VEHICLES HAMMERING BY ME AT 75MPS I TRIED TO GO AGAIN. TO NO AVAL THE VEHCLE WOULD NOT MOVE. I CALLED A TOW TRUCK, MOVED MY WIFE, 11 YEAR OLD SON AND 16 YEAR OLD SON OVER THE GUARD RAIL TO SAFETY. THE TRANSMISSION IS BAD, ALONG WITH ALL THE OTHERS POSTED ON THE INTERNET. WHAT GIVES? THIS VEHICLE HAS 88,000 MILES ON IT AND IM TOLD GM WONT FIX IT BECAUSE TH 5 YEARS IS UP ON THE WARRANTY. WHAT DOES 5 YEARS HAVE TO DO WITH ANYTHING WHEN THIS IS HAPPENING EVERYWHERE TO THIS PARTICULAR VEHICLE?? *TR

MANUFACTURER DEFECT TO TRANSMISSION. *TR

TRANSMISSION DEAD-RACING RPM WITHOUT GEAR SHIFTING, BROKEN WAVE PLATE INSIDE TRANSMISSION IS THE CAUSE. WATER LEAKING FROM SUNROOF WHEN RAINING, CONSTANT WHINNING IN STEERING COLUMN. ALL THESE MAJOR PROBLEMS UNDER 75K MILES. *TR
