EXTERIOR LIGHTING
DAY TIME RUNNING LIGHTS BURN OUT ON GMC ACADIA. LIGHT GETS SO HOT, THEY MELTED AND BURNED THE HEADLIGHT ASSEMBLY. THIS IS A POSSIBLE FIRE HAZARD. I HAVE HAD THE LAMPS REPLACED 4 TIMES BY THE DEALERSHIP, BETWEEN BOTH HEADLIGHTS ASSEMBLIES. LESS THEN 60,000 MILES, THE HEADLIGHT ASSEMBLY WAS SO BADLY BURNT AND BRIDLE, IT FELL APART IN THE TECHNICIANS HAND AND IT WOULD NOT HOLD A LAMP ANYMORE. THE WHOLE ENTIRE HEADLIGHT ASSEMBLY NEEDS REPLACED. THE PROBLEM IS CAUSED BY HEAT FROM THE HALOGEN LAMPS. AN EASY FIX COULD BE REPLACING THE HALOGEN LAMPS WITH LEDS. THESE ARE DAY TIME LAMPS ONLY AND ARE ON ALL THE TIME. THIS IS A VERY POOR DESIGN AND CRAFTSMANSHIP BY GMC AND A SAFETY ISSUE THEY ARE NOT WILLING TO CORRECT. I HAVE TRIED ADDRESSING THE ISSUE DIRECTLY WITH GMC WITH NO LUCK. *TR

FLUID LEAKED FROM MASTER CYLINDER TO POWER BOOSTER NO VISIBLE LEAKS REPAIRED AT MY EXPENSE ABOUT A WEEK LATER A BULLETIN FROM GM THAT WAS TO EXTEND MY WARRANTY TO 10 YEAR 120000 MILES. THERE IS A PROCESS IN PLACE TO RETURN MY MONEY. NO SAFETY RECALL ! BOTH FRONT STRUTS HAVE GONE OUT . THE AIR CONDITIONER IS CAUSING PROBLEMS BECAUSE OF OFF AND ON COOLING. ALL OF THIS IS WITH IN 55000 MILES, THE CAR HAS 55055MILES AS OF THIS DATED. THERE SEEMS TO BE A PROCESS OF NO SAFETY RECALLS BUT TO ISSUE EXTENDED WARRANTY. WE ALL KNOW WHAT RECALLS DO TO SALES. *TR

TRAVELING ON THE INTERSTATE WITH MY 3 YEAR OLD DAUGHTER WHEN TRANSMISSION FAILURE MESSAGE CAME ON. HAS COME ON MULTIPLE TIMES, REQUIRING ME TO PULL ONTO THE SHOULDER OF THE BUSY ROAD WITH SEMIS SPEEDING PAST. GMC IS AWARE OF THIS ISSUE, YET REFUSES TO ADDRESS IT ON A LARGE-SCALE. SOMEONE IS GOING TO GET KILLED BEFORE THEY ACTUALLY COME TO ACTION ON THIS MANUFACTURING DEFECT!!! *TR

I HAD TO STOP ON THE SIDE OF THE ROAD IN THE BRONX. EVENTUALLY GOT IT TO THE DEALERSHIP WHO REPLACED THE REVERSE CLUTCH PLATE. *TR

ENGINE AND ENGINE COOLING, POWER TRAIN, STEERING
8/26/2011 - 71,309 MILES - WATER PUMP WENT OUT AND HAD TO BE REPLACED. 5/07/2012 - 86,885 MILES - TRANSMISSION SHUTTERED WHEN COMING TO A STOP IN TRAFFIC. WOULD NOT START AND HAD TO BE TOWED TO MECHANIC. TRANSMISSION ASSEMBLY REPLACED WITH GM REMAN TRANSMISSION DUE TO BROKEN REVERSE WAVE PLATE THAT DAMAGED THE CARRIER, SUN SHELL AND METAL THROUGHOUT. ALSO DETECTED AN OIL LEAK IN THE ENGINE FRONT COVER THAT NEEDED TO BE REPAIRED AND HEARD POWER STEERING NOISE SO BLED POWER STEERING SYSTEM. 12/31/2012- 100,947 MILES - HEADLIGHT SWITCH FELL INSIDE DASH PANEL. 7/26/2013 - 112,506 MILES - POWER STEERING HAS NEVER WORKED PROPERLY. IT HAS ALWAYS MADE NOISES AND HAS BEEN STIFF. HAD IT BLED SEVERAL TIMES WITH NO IMPROVEMENT. POWER STEERING WENT OUT WHILE MAKING A LEFT HAND TURN INTO A BUSY INTERSECTION. AT SHOP NOW TO DETERMINE IF IT NEEDS A NEW POWER STEERING PUMP, RACK, AND/OR SERPENTINE BELT. I HAVE READ MANY COMPLAINTS WITH THE SAME ISSUES AS THOSE THAT I HAVE EXPERIENCED. I AM DISAPPOINTED THAT GM ISN'T MORE CONCERNED ABOUT THE SAFETY OF THEIR CONSUMERS AND THE RELIABILITY AND QUALITY OF THEIR VEHICLES. I HAVE NEVER OWNED SUCH A LEMON! I PERSONALLY WILL NEVER OWN ANOTHER GM PRODUCT. GOING BACK TO LEXUS. *TR

STEERING
IN THE WINTER OF 2012, THE STEERING STARTED TO GET MORE DIFFICULT WHILE PARKING AND BACKING OUT OF SPACES. IT WHINED A BIT. SERVICE AT COLLECTION AUTO TOLD ME TO REPLACE THE POSITION SENSOR. NO CHANGE. THE STEERING GOT WORSE, FLUID BEGAN LEAKING, AND I WAS INVOLVED IN TWO NEAR CRASHES WITH YOUNG CHILDREN IN THE CAR. ONE THE POWER STEERING WENT OUT UPON ENTERING A FREEWAY RAMP. IT RETURNED TO NORMAL AFTER ABOUT 10 SECONDS. IT THEN AGAIN HAPPENED, BUT TOTAL STEERING FAILURE WHILE TURNING INTO A SHOPPING CENTER ACROSS ONCOMING TRAFFIC. THE CAR HAD TO BE TOWED. WE TOOK IT BACK AND WERE TOLD THAT THE PUMP AND RACK AND PINION NEEDED TO BE REPLACED. AFTER A GOOD DEAL OF DIGGING AND SPEAKING WITH SEVERAL DEALERS OTHER THAN THE ONE THAT RECOMMENDED THE CHANGE FOR PUMP AND RACK AND PINION, WE FOUND OUT THAT THERE WAS NO NEED TO REPLACE THE POSITION SENSOR AND THERE WERE SEVERAL SERVICE BULLETINS TO DEALERS TO REPLACE THESE WITH REDESIGNED PARTS DATING TO 2012. IT CURRENTLY IS AT A DEALER WHO IS WORKING WITH GM TO FIX THE PROBLEM. *TR

AIR BAGS, STEERING, STRUCTURE
PROBLEM #1 OF 3: DURING HEAVY RAINS, WATER WOULD LEAK IN THROUGH THE SUN VISORS ON BOTH SIDES. TOOK IT TO THE DEALERSHIP SEVERAL TIMES. THEY SAID THE DRAIN TUBES FROM THE SUNROOF WERE CLOGGED, THEY BLEW IT OUT, WHEN THAT DIDN'T WORK, THEY CHARGED ME TO PUT IT LONGER TUBES, WHEN THAT DIDN'T WORK, THEY SAID IT WAS BECAUSE THEY ONLY REPLACED THE FRONT TUBES, NOT THE BACK. PROBLEM #2 OF 3: WHEN DRIVING THROUGH WATER PUDDLES AT LOW SPEED I LOSE POWER STEERING FOR A BRIEF TIME (WHICH IS TROUBLESOME WHEN TURNING). PROBLEM #3 OF 3: TWO WARNING LIGHTS FOR AIRBAGS COME ON EVERYTIME I START THE VEHICLE. I CAN PUSH A BUTTON EACH TIME TO MAKE THE WRITTEN WARNING GO AWAY, BUT THE RED LIGHT WITH A PICTURE STAYS ON. NOT SURE IF THE AIRBAGS WOULD DEPLOY OR NOT. *TR

WE LIVE IN CAMARILLO CA. WE LEFT TO GO TO SACRAMENTO FOR MY DAUGHTERS COLLEGE ORIENTATION. ABOUT TWO HOURS INTO THE FIRST LEG OF OUR TRIP THE DIC INFORMED US THE TRANSMISSION WAS OVERHEATING AND THE CAR SHOULD BE IDLED FOR IT TO COOL OFF. WE DID JUST THAT. AFTER IT COOLED OFF WE BEGAN DRIVING AGAIN. IT DID THIS ONCE MORE BEFORE WE ARRIVED IN SAN LUIS OBISPO. WE LEFT THE NEXT DAY TO SACRAMENTO. AGAIN ABOUT TWO HOURS INTO THE DRIVE THE SAME THING OCCURRED. WE IDLED THE CAR, TRANS COOLED OFF AND WE GOT UNDER WAY AGAIN. IT DID THIS ONCE MORE BEFORE WE ARRIVED IN SACRAMENTO.. WHILE IN SACRAMENTO IT DROVE FINE. ON OUR RETURN TRIP IT DID THIS TWICE ON THE WAY HOME. AFTER LOOKING BACK IT SEEMED TO DO THIS WHEN WE WERE GOING UP AN INCLINE. WE WERE NOT TOWING ANYTHING EITHER. WE WERE LUCKY THAT WHILE ON THE FREEWAY WHEN WE RECEIVED THE OVERHEAT NOTICE THAT THE CAR DID NOT LOSE POWER AND SLOW DOWN WHILE ON THE FREEWAY IN TRAFFIC. THIS IS THE THIRD TRANSMISSION FOR THIS VEHICLE SINCE WE PURCHASED IT IN 2008. *TR

POWER TRAIN, FUEL SYSTEM, GASOLINE
AT DRIVING SPEED IT WAS NOTICED THAT ACADIA BEGAN TO FAIL TO SHIFT GEARS, BASICALLY ON HIGHWAY IT IS STUCK IN FIRST GEAR AND AFTER FINDING A PLACE TO STOP, IT WILL NOW NOT GO INTO REVERSE. HAVE FOUND THE EDMUNDS, ASK AND NUMEROUS OTHER SITES ARE FULL OF TRANSMISSION COMPLAINTS CONCERNING THE 2008 ACADIA AND IT'S FAILURES. THIS TRANSMISSION HAS HAD MINOR ISSUES IN PAST, MINOR LEAK AND SOME WHINING, BUT THIS IS A COMPLETE AND HAZARDOUS FAILURE WHILE DRIVING IN TRAFFIC. I HAVE SINCE LEARNED THAT THIS IS A COMMON AND KNOWN ISSUE TO GENERAL MOTORS COSTING THE CONSUMERS APPROX. $3000 TO $3500 PER INSTANCE. IS THERE NOTHING TO BE DONE TO ASSIST THE CONSUMERS? *TR

I WAS DRIVING MY ACADIA TO WORK ON MONDAY MORNING AND IT STARTED HAVING TRANSMISSION PROBLEMS, IT WOULD NOT SHIFT IN THE LOWER GEARS AND WOULD REV UP TO 4-5 RPM BETWEEN GEARS. I DROVE IT TO A TRANSMISSION SHOP THE NEXT MORNING AND THEY DIAGNOSED IT, NEEDED A WHOLE NEW TRANSMISSION. UPON LEAVING THE TRANSMISSION SHOP, IT COMPLETELY STOP MOVING, CAUSING ME TO ROLL TO A COMPLETE STOP ON A HIGHWAY. I GOT IT PULLED OVER, STOPPED THE VEHICLE AND RESTARTED IT. I WAS ABLE TO DRIVE A BLOCK OR SO BEFORE IT STOPPED AGAIN. I WAS STRANDED AND STUCK IN THE MIDDLE OF THE ROAD. I WAS FINALLY ABLE TO GET IT TO A PARKING LOT AND HAD IT TOWED TO A DEALER TO LOOK AT. *TR

I WAS AT MY SON'S BASEBALL GAME AND WENT TO MOVE MY VEHICLE WHEN I WAS PULLING OUT OF THE PARKING LOT AND THE VEHICLE STARTED REVVING AND WOULD NOT MOVE OTHER THAN COASTING (SINCE I WAS ON A HILL). I WAS 3 HOURS FROM HOME AND HAD TO HAVE THE VEHICLE TOWED TO THE TUNE OF $300.00 +. I HAVE SINCE HAD TO HAVE THE TRANSMISSION REPLACED. THIS HAS COST OVER $4500.00 NOT TO MENTION HAVING TO DRIVE 2 VEHICLES WITH MY FAMILY SINCE THE ACADIA WAS THE LARGER OF OUR VEHICLES. *TR

ENGINE AND ENGINE COOLING
I HAVE A 2008 ACADIA AND IT JUST STALLS OUT FOR NO REASON. THIS IS A VERY UNSAFE PROBLEM AND GMC -ACCORDING TO THE DEALER DOES NOT STAND BEHIND THIS WIDE SPREAD ISSUE. THE DEALER AND GMC CAN'T TELL ME WHAT IS CAUSING IT AND THEY GIVE ME THE VEHICLE BACK AND SAY IF IT HAPPENS AGAIN BRING IT IN AND WE WILL LOOK AT IT BUT THEY CAN NEVER FIND ANYTHING WRONG. I FEAR GETTING IN THIS VEHICLE BECAUSE I NEVER KNOW IF IT IS GOING TO JUST STALL OUT ON ME WHILE IN TRAFFIC ON A MAJOR HIGHWAY. THERE ARE NUMOURS POSTS ON MANY WEB SITES ABOUT THIS VEHICLE AND HOW GMC WILL NOT HELP ANYONE. SOME OF THE WEB SITES ARE WWW.TOPIX.COM AND WWW.EDMUNDS.COM. I THINK THIS VEHICLE NEEDS TO BE ON A TOTAL VEHICLE RECALL. *TR

OUR AREA OF TEXAS IS DROUGHT PRONE SO NO MORE SIGNIFICANT RAIN UNTIL JULY 14-16. WATER POURS IN THE FRONT WINDSHIELD, BOTH DRIVER AND PASSENGER SIDE. WATER FROM CURTAIN AIRBAGS AND UNDER THE DASH. STANDING WATER IN THE FLOOR BOARD. OBD LIGHT IS ON AND MY PARKING BREAK WARNING LIGHT TURNS ON AND OFF. PARK ASSIST GOES ON AND OFF. THE WARNING CHIME COMES ON WHILE DRIVING AND WON'T TURN OFF.

TL* THE CONTACT OWNS A 2008 GMC ACADIA. THE CONTACT STATED THAT THE AIR BAG, THE STABILITY CONTROL, AND TRACTION CONTROL WARNING LIGHTS FAILED ALONG WITH THE DAYTIME RUNNING LIGHTS FAILED. THE CONTACT ALSO STATED THAT THE ENGINE OVERHEATED AND THE POWER STEERING ALSO FAILED. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE LIGHT BULB WAS REPLACED BUT THE FAILURE RECURRED. THE DEALER WAS ALSO UNABLE TO DIAGNOSE THE OTHER FAILURES. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 33,000 AND THE CURRENT MILEAGE WAS 112,000.

VEHICLE SPEED CONTROL, POWER TRAIN, STEERING
ABOUT A WEEK AGO MY FAMILY AND I WERE DRIVING HOME FROM VACATION AND HAD BEEN ON THE ROAD FOR ABOUT 3.5 HOURS. AS WE PULLED OUT OF A DRIVEWAY ABOUT 5 MINUTES FROM OUR HOME THE CAR ENGINE LIGHT CAME ONE, THE CAR WOULD NOT GAIN SPEED LIKE NORMAL AND IT BEGAN TO OVER HEAT RAPIDLY. WE TOOK SIDE ROADS AND SLOWLY CRAWLED HOME. I TOOK IT INTO THE SHOP THE NEXT DAY AND IT CAME BACK WITH A CRACK IN THE RADIATOR AND CODES P0700 AND P07016, WHICH THEY CONFIRMED TO BE A TRANSMISSION ISSUE AND SUGGESTED TO HAVE A SPECIALIST LOOK AT IT. I DID SOME RESEARCH AND FOUND THAT THIS ARE COMMON CODES THAT COME BACK FOR THE 2007 AND 2008 ACADIA'S THAT REQUIRE A REBUILD/REPLACED TRANSMISSION WITH AN AVERAGE COST OF $4000. THIS IS A KNOWN ISSUE WITH GMC FOR MANY YEARS AND THEY HAVE YET TO ACKNOWLEDGE IT. I AM VERY LUCKY TO NOT HAVE HAD A WORSE INCIDENT IN DISCOVERING THIS ISSUE, BUT I AM VERY CONCERNED THAT AT ANY MOMENT THE TRANSMISSION WILL GO OUT, AND WE DO NOT HAVE $4000 TO DROP INTO A NEW ONE, ESPECIALLY WHEN I JUST SPENT $650 ON A NEW RADIATOR. THESE ARE NOT PROBLEMS THAT A RELIABLE CAR, THE 2008 ACADIA, UNDER 100,000 MILES SHOULD BE HAVING. GMC NEEDS TO OWN UP TO THESE ISSUES AND TAKE ACTION TO CORRECT IT BEFORE SOMETHING MORE SERIOUS HAPPENS. *TR

WE ARE A FAMILY OF 5 DRIVING ALONG THE HIGHWAY WHEN THE CHECK ENGINE LIGHT CAME ON. WE STOPPED AND PUT THE CAR INTO PARK. WHEN I WENT TO PUT INTO DRIVE, THE CAR WOULD NOT ENGAGE. FINALLY AFTER A FEW MINUTES WE WERE ABLE TO GET THE CAR GOING AGAIN, BUT THE CAR WOULD NOT SHIFT ITSELF (AUTOMATIC TRANSMISSION). WE THEN HAD TO DRIVE ALONG THE SIDE OF THE HIGHWAY FOR 13 MILES TO THE NEXT TOWN WITH THE HAZARDS ON AT 20 MILES PER HOUR. WENT TO A CHEVY DEALERSHIP AND AFTER THEY READ THE CODES, THERE APPEARS THAT THE TRANSMISSION IS COMPLETELY OUT. WE WERE MORE THAN 800 MILES AWAY FROM HOME ON VACATION IN MISSOURI. THE CAR IS STILL IN MISSOURI AT THE DEALERSHIP, AS THEY WILL NOT BE ABLE TO TAKE THE TRANSMISSION APART UNTIL EARLY NEXT WEEK. *TR

AS I WAS PULLING OFF OF THE INTERSTATE ONTO ROCKVILLE RD I NOTICED THAT THE CAR UPSHIFTED FROM 3RD VERY VIOLENTLY. I THEN HIT A STOP LIGHT AND IT DOWSHIFTED PRETTY ROUGH AS WELL. I THOUGHT UH OH AND NOTICED THE CHECK ENGINE LIGHT COME ON. WHEN I PULLED AWAY FROM THE LIGHT I NOTICED THE CAR WAS MOST LIKELY STUCK IN 3RD GEAR AS THE RPMS MATCHED THE MPH AND FROM DRIVING A STICK ALL THOSE YEARS THEY MADE SENSE. I LATER FOUND OUT THIS WAS DONE ON PURPOSE TO STICK THE TRANSMISSION IN 3RD GEAR TO FURTHER DAMAGE IT AND ALLOW YOU TO CONTINUE TO DRIVE. I GOT TO WORK AND HAD ONSTAR RUN A DIAGNOSTIC. IT CAME BACK WITH A P2715 CODE FOR THE TRANSMISSION CONTROL. AFTER LOOKING INTO THIS CODE IT APPEARS TO INVOLVE THE 3-5-R WAVEPLATE THAT CONTROLS THE CLUTCH FOR THESE GEARS. I, OF COURSE, AM 6 MONTHS OUT OF WARRANTY ON THE DRIVE TRAIN. AFTER CONFIRMATION WITH GMC IT WAS THE WAVE PLATE. THIS APPEARS TO BE A COMMON PROBLEM CROPPING UP WITH THIS TRANSMISSION WHEN YOU LOOK AROUND SOCIAL MEDIA. *TR
