2010 GMC ACADIA Power Train Problems

power train came up on a computer check witch looks like the same problem that is already on here my engine light is on as long as my abs and track control light stable light is on

2010 GMC Acadia transmission had to be replaced due to faulty wave plate. I have seen many others with this same problem. GM is aware of the issue and even issued a special warranty for 2007-2009 models. 2010 models are having this same issue. GM should stand behind their products and issue a recall. This cost us over $3000.

THE TRANSMISSION SLIPS. WHEN YOU START THE VEHICLE IT SOMETIMES STARTS IN THE WRONG GEAR AND NEEDS TO BE SHUT OFF AN RESTARTED, OTHERWISE IT RUNS ON TOO MANY RPM. AT TIMES WHEN PUSHING ON THE GAS, AFTER A STOP AT A LIGHT, IT DOES NOT MOVE FOR A WHILE. WHEN IT DOES MOVE IT JERKS AND ABRUPTLY STARTS. THE RUNNING DAY HEAD LAMP OVERHEATS AND BURNS OUT THE LIGHT BULB, CAUSING IT TO EXPLODE.

FIRST PROBLEM IS THAT THE POWER STEERING IS HARD TO TURN WHEN NOT MOVING OR WHILE DRIVING AT SLOWER SPEEDS AS IF THERE IS NO POWER STEERING AT ALL. SECOND PROBLEM IS THE TRANSMISSION OCCASIONALLY WILL NOT SHIFT FROM 1ST GEAR WHICH WILL CAUSE ME TO PULL OVER TO A COMPLETE STOP THEN ACCELERATE AGAIN ALLOWING IT TO SHIFT.

MY ACADIA STARTED ACTING UP AND SHIFTING GEARS HARD WHEN GOING UP MOUNTAINS THEN IT STARTED NOT WANTING TO CHANGE GEARS FROM 3 TO 4 AND THE CODE RAN WAS SHIFTER STUCK ALSO ONCE GETTING IT IN THE SHOP WAS READING 3 OTHER TRANSMISSION CODES AND WAS TOLD MY TRANSMISSION WILL NEED TO BE REBUILT FOR $2800.00 I WAS ALSO TOLD THAT THIS VEHICLE WHEN MADE WAS NOTORIOUS FOR TRANSMISSION ISSUES AND THAT GM WAS COVERING THE PROBLEM UP TO 100K MILES MINE NOW HAS 168K BUT I WAS NEVER TOLD AND IT DIDN'T SHOW AS A RECALL TO HAVE ANYTHING DONE ABOUT THIS. AS A SINGLE MOTHER OF 3 $2800. ISN'T EASY TO JUST COME UP WITH ESPECIALLY AFTER HAVING HAS OTHER PROBLEMS THAT HAD TO BE FIXED. WHAT CAN BE DONE ABOUT THIS?

POWER CHAIN WENT OUT WHILE TAKING A CORNER AND ALMOST PUT MY HUSBAND AND DAUGHTER IN THE DITCH, HE STOPPED AND ALMOST GOT REAR-ENDED. MULTIPLE PEOPLE HAVE TOLD ME THIS IS AN ISSUE WITH THIS VEHICLE, THIS COULD HAVE CAUSED A MAJOR ACCIDENT.

THIS VEHICLE HAS BEEN A PROBLEM SINCE I PURCHASED IT. UNFORTUNATELY, MY STATE DOES NOT HAVE A LEMON LAW FOR USED VEHICLES SO I HAVE BEEN STUCK WITH REPAIR AFTER REPAIR. #1 THE BATTERY. I PURCHASED THIS VEHICLE IN 2016 AND I HAVE HAD TO REPLACE THE BATTERY TWICE ALREADY. THIS VEHICLE HAS KILLED CELLS IN MULTIPLE BATTERIES. #2 THE TRANSMISSION. WHEN I INITIALLY PURCHASED THIS VEHICLE OCCASIONALLY IT WOULD NOT SMOOTHLY SHIFT INTO 3RD GEAR. I TOOK IT BACK TO THE DEALER MULTIPLE TIMES, BUT OF COURSE THE ISSUE WOULD REPLICATE DURING THEIR TEST DRIVE SO THEY COULDN'T DIAGNOSE THE ISSUE. THE ISSUE IS THAT THE TRUCK WILL NOT SHIFT CORRECTLY, BUT THE PROBLEM NORMALLY CORRECTS IF YOU TURN THE VEHICLE OFF AND THEN TURN IT BACK ON. THE PROBLEM IS THAT YOU NEVER KNOW WHEN THE TRUCK WILL NOT SHIFT GEARS. THIS IS PROBLEMATIC WHEN YOU HAVE A...

AFTER I PULL INTO MY DRIVEWAY AND PUT MY CAR IN PARK AND TURN OFF THE IGNITION THE CAR GETS STUCK IN PARK AND WONT SHIFT BACK OUT FOR HOURS. ALSO WHEN I'M DRIVING THE CAR STATES THAT THE ENGINE IS IN REDUCED POWER AND THE TRACTION CONTROL IS OFF AND TO SERVICE STABILITRAK. THIS IS A COMMON PROBLEM WITH THIS VEHICLE OF ALL YEARS FROM 2007 TO THE PRESENT IT NEEDS TO BE FIXED 6 DEATHS SO FAR AND STILL NO RECALL TO FIX MY CAR I DONT WANT TO END UP BEING ANOTHER DEATH IF YOU DONT FIX THIS ISSUE

WHILE DRIVING, MY TRANSMISSION WAS SLIPPING OCCASIONALLY AND THEN IT BECAME A DAILY OCCURRENCE AND MULTIPLE TIMES A DAY OCCURANCE. WHEN IT SLIPPED, I COULD FEEL IT AND THE RPMS WOULD INCREASE. I TOOK IT TO A LOCAL TRANSMISSION SHOP AND IT TURNED OUT TO BE A 3/5 WAVE PLATE FAILURE. THE BROKEN PARTS DAMAGED THE REST OF MY TRANSMISSION AND I HAD TO HAVE A COMPLETE REBUILD. I WAS LUCKY THAT I BROUGHT IT IN TO BE CHECKED AS I FOUND OUT THAT THIS ISSUE COULD HAVE CAUSED THE TRANSMISSION TO FAIL COMPLETELY WHICH COULD HAVE PUT THE OCCUPANTS OF MY VEHICLE AT RISK OF INJURY OR DEATH DUE TO AN ACCIDENT CAUSED BY LOSS OF POWER DUE TO A DRIVETRAIN FAILURE. I HAVE ALSO READ THAT THERE WAS A RECALL FOR THE SAME ISSUE ON THE 07-09'S AND THAT RECALL WAS #14404 SPECIAL COVERAGE TRANSMISSION CLUTCH WAVE PLATE....

THE TIMING CHAIN NEEDS TO BE REPLACED ON THE 2010, WHICH IS THE SAME ISSUE GMC HAD WITH THE 2009S, HOWEVER, THE 2010 ISN'T COVERED, BUT THE 2009 WAS. I'VE READ THAT GMC KNOWS THAT THERE IS AN ISSUE, BUT THEY JUST AREN'T COVERING IT YET.

AFTER TAKING VEHICLE TO DEALERSHIP AND PAYING TO HAVE THE EVAP SYSTEM FIXED MY CHECK ENGINE LIGHT CAME BACK ON BEFORE EVER LEAVING THE DEALERSHIP. NO CODES WOULD SHOW WHEN CHECKED. NOW THEY ARE SAYING THAT IT MUST BE THE TIMING CHAIN AND THAT IT WILL COST OVER $2000 TO REPAIR. I HAVE SPOKEN TO SEVERAL OTHER MECHANICS WHO HAVE STATED THAT IT IS A KNOWN PROBLEM IN THIS MODEL CAR. AFTER CHECKING IT SEEMS THAT SEVERAL OTHER YEARS HAVE BEEN RECALLED AND NO CHANGES WERE MADE TO THE PRODUCT BUT YET THE 2010 IS NOT INCLUDED BUT IT IS A KNOWN DEFECT IN THAT YEAR AS WELL. I BELIEVE GMC SHOULD BE REQUIRED TO FIX THIS SINCE IT IS A KNOW DEFECTIVE SYSTEM.

AT 60,000.00 THOUSAND MILES MY TIMING CHAINS NEEDED REPLACED (JUST LIKE THE 2009 WHICH HAS A RECALL) THEN AT 79,000 MILES MY WAVE PLATE CRACKED ON MY TRANSMISSION (WHICH THERE IS A RECALL ON THE 2009 MODEL FOR THE EXACT SAME THING) MY CAR WAS A EARLY 2010 MODEL AND IT LOOKS LIKE THE 2009 ISSUES ARE PROBLEMS ON MY CAR. I THINK IT'S INSANE THAT GM CAN'T STAND BEHIND THEIR WORK BETTER THAN THIS. THE RECALL'S SHOULD COVER THE 2010 MODELS THAT WERE MANUFACTURED WITH 2009 PARTS!!!

79,100.00 MILES WAVEPLATE FAILURE. ENTIRE TRANSMISSION REBUILD REQUIRED.

TIMING CHAIN NEEDED REPLACEMENT DUE TO STRETCH AND CHECK ENGINE LIGHT AT 137,882 WHICH COST $2,049. THIS ISSUE WAS COVERED UNDER SPECIAL WARRANTY FOR 2007-2009 MODEL YEARS, BUT THE 2010 IS NOT COVERED. MY UNDERSTANDING OF GMC'S FIX IS THAT NOTHING CHANGED WITH THE TIMING CHAIN AND THE OIL SYSTEM LIFE WAS LOWERED AS TO WHEN AN OIL CHANGE WAS RECOMMENDED BY THE VEHICLE (MORE FREQUENT OIL CHANGES). I HAVE COMPLETED ALL SCHEDULED OIL CHANGES BASED ON THE AUTOMATED PROMPT FROM THE VEHICLE AND STILL HAD TO COMPLETE THIS COSTLY REPAIR OUT OF POCKET. I WOULD LIKE TO SEE THIS KNOWN ISSUE ALSO COVERED BY THE SPECIAL WARRANTY ON NEWER VEHICLES AND BE REIMBURSED FOR MY EXPENSES.

TL* THE CONTACT OWNS A 2010 GMC ACADIA. WHILE DRIVING VARIOUS SPEEDS, THE GEAR SHIFT FAILED TO WORK. THE VEHICLE WAS TAKEN TO THE DEALER (HENRY BROWN BUICK GMC LOCATED AT 1550 E DRIVERS WAY, GILBERT, AZ 85297; (480) 835-0900). THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE RECURRED SEVERAL OTHER TIMES. THE MANUFACTURER WAS NOT CONTACTED AND WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 70,529.

MY CAR HAS LESS THAN 73000 MILES ON IT AND THE ENGINE LIGHT CAME ON. THE CODE INDICATED IT WAS THE TIMING CHAIN. THE CAR BROKE DOWN ON THE HIGHWAY AND HAD TO BE TOWED TO A REPAIR SHOP. AFTER RESEARCHING THE PROBLEM, I DISCOVERED THAT THIS SAME PROBLEM HAS HAPPENED TO A VERY LARGE NUMBER OF OWNERS OF BOTH CHEVROLET TRAVERSE AND GMC ACADIA. THE PROBLEM WAS SUPPOSE TO HAVE BEEN FIXED AFTER 2009 BUT 2010'S AND LATER MODELS ARE STILL HAVING THIS PROBLEM. SOMETHING NEEDS TO BE DONE ABOUT THIS. GM WILL NOT HELP WITH REPAIRS EVEN THOUGH THE VEHICLE HAS LESS THAN 100,000 MILES ON IT. THAT WAS THE ONLY RUNNING VEHICLE WE HAD!

WHEN I NEED TO DRIVE FROM A SLOW SPEED TO A HIGH SPEED LIKE WHEN ENTERING A FREEWAY THE RPM'S START GOING CRAZY. WHEN I PRESS ON THE GAS THE CAR BARELY MOVES AND THE RPM'S GO WAY UP AND DON'T STOP UNTIL I PULL OVER. I HAD A CAR BEHIND ME THAT ALMOST CRASHED INTO ME BECAUSE MY VEHICLE WOULD NOT ACCELERATE. I TOOK IT TO A REPAIR SHOP AND WAS TOLD THAT IT NEEDS A NEW TRANSMISSION AND THIS VEHICLE IS KNOWN FOR HAVING A BAD TRANSMISSION. TURNS OUT THAT THERE WAS A RECALL FOR THE SAME ISSUE ON THE 08-09'S AND MINE IS A 2010 THAT RECALL WAS #14404 SPECIAL COVERAGE TRANSMISSION CLUTCH WAVE PLATE. I AM SURE THAT THIS ONE NEEDS TO BE RECALLED AS WELL. THIS IS A HUGE SAFETY HAZARD SOMEONE COULD GET HURT REALLY BAD.

ENGINE LIGHT PROMPTED A TRIP TO THE GMC DEALER TO HAVE THE VEHICLE CHECKED OUT. WE WERE TOLD IT WAS THE TIMING CHAIN AND IT WAS A KNOW PROBLEM, HOWEVER GMC IS NOT COVERING IT.ALSO TRANSMISSION IS SLIPPING AND NEEDS TO BE REPLACED GMC ACADIA ARE KNOWN FOR BOTH PROBLEMS AND WILL NOT FIX.IT'S GOING TO COST AROUND $5,000 TO FIX BOTH THESE NEED TO BE RECALLED,I HAD A CASE OPEN WITH GMC AND THEY WILL COVER NOTHING. WORST SUV EVER

AT 80,000 MILES, AFTER PULLING OUT OF PARKING, WHEN I APPLIED BRAKES THE CAR STARTED MAKING RUMBLING NOISE FROM THE ENGINE AND LURCHED FORWARD DESPITE PRESSING ON BRAKES TO STOP. PULLED INTO A PARKING SPOT, WHILE CONTINUING TO FIGHT LURCHING OF VEHICLE AND TURNED CAR OFF TO CHECK ENGINE OIL, TRANSMISSION OIL, AND POWER STEERING OIL LEVELS. ALL WERE FINE. WHEN ATTEMPTED RESTART OF VEHICLE, LOUD RUMBLING NOISE FROM ENGINE, CHECK ENGINE LIGHT FLICKERED AND THE CAR FAILED TO START. REQUIRED A TOW HOME FROM 100 MILES AWAY AND $400. HOOKED UP OBD, AND RECEIVED THE FOLLOWING FAULTS P0008, P0303, P0305, P0017, P0300, P0301. AFTER RESEARCHING ON-LINE, COMMON FAULTS FOR TIMING CHAIN ISSUE ESTIMATE $3-4 THOUSAND REPAIR. ALSO, FOUND 2007-2009 ACADIA RECEIVED EXTENDED WARRANTY FOR SAME ISSUE. HOWEVER, 2010 NOT COVERED DESPITE FINDING APPROXIMATELY 15 IDENTICAL 2010 GMC ACADIA ON NHTSA SITE. I WILL BE CALLING DEALERSHIP FIRST WORKDAY, HOWEVER...

TRANSMISSION CONTROL MODUAL AND THE WAVY PLATE- TRANSMISSION REBUILD- TRANSMISSION FAILURE

WHILE IN DRIVE, GOING UPHILL, FOR EXAMPLE AN UP RAMP IN A PARKING GARAGE, THE CAR ROLLS BACKWARDS IF I TAKE MY FOOT OFF THE BRAKE. IT HAS ALWAYS ROLLED A BIT BEFORE CATCHING IN THE PAST, BUT NOW IT WILL ROLL BACK WITHOUT STOPPING IF I RELEASE THE BRAKE.

ENGINE LIGHT PROMPTED A TRIP TO THE GMC DEALER TO HAVE THE VEHICLE CHECKED OUT. WE WERE TOLD IT WAS THE TIMING CHAIN AND IT WAS A KNOW PROBLEM, HOWEVER GMC IS NOT COVERING IT. WHAT? REALLY? SO, WE HAVE TO PAY 3000 BUCKS FOR GMC KNOWN PROBLEM. NEVER BUYING ANOTHER GMC.

GMC KNEW OF TIMING CHAIN ISSUES FOR 2007-2009 AND EXTENDED THE WARRANTY FOR 10 YEAR 120,000 MILES. THEY CONTINUE TO HAVE THE SAME TIMING CHAIN ISSUES THROUGH 2010 MODELS AND WILL NOT REPLACE THEM UNDER THIS WARRANTY. MY ACADIA IS 2010 MODEL, BUT MANUFACTURED IN 2009 AND GMC WILL NOT ASSIST WITH THE REPLACEMENT OF THE STETCHED TIMING CHAIN. THEY PRIDE THEMSELVES FOR "CONSUMER SATISFACTION PROTECTION" BUT WILL NOT STAND UP TO THEIR PRODUCT UNDER FOR ISSUES THEY ARE FULLY AWARE OF.

THE CAM SHAFT ENGINE CORRELATION CODE INDICATED STRETCHED TIMING AND CHAIN GUIDES. EXTENDED WARRANTEES UP TO 10 YEARS AND 120,000 MILES HAVE BEEN OFFERED FOR 2007 AND 2009 GMC ACADIAS WITH THE SAME PROBLEM. TO DATE THEY HAVE NOT BEEN OFFERED FOR THE 2010 MODEL EVEN THOUGH IT'S THE SAME ISSUE. MINE FAILED AT 51,000 MILES. HAD TO HAVE THE TIMING CHAINS REPLACED. DEALERSHIP REPAIRED WITH GM PAYING HALF. THIS SHOULD BE A RECALL DUE TO THE FACT MY CAR WAS MANUFACTURED IN 2009 AND SHOULD FALL UNDER THE ABOVE MENTIONED RECALL AS THE FAILURE IS FOR THE SAME REASON. I AM CONCERNED WHY SPECIAL COVERAGE #11340 DOES NOT APPLY TO 2010 VEHICLES OF THIS NATURE AS THERE ARE MANY ISSUES WITH THIS THAT HAVE NOT BEEN RESOLVED IN THE 2010 VEHICLE.

TL* THE CONTACT OWNS A 2010 GMC ACADIA. THE CONTACT STATED THAT THE TRANSMISSION FAILED. THE VEHICLE LOST ACCELERATION AND EMITTED A WHINING NOISE. THE FAILURE WAS EXPERIENCED NUMEROUS TIMES. THE DEALER DIAGNOSED THAT THERE WAS A FAILURE CODE RELATED TO THE TRANSMISSION. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 80,000.

TIMING BELT ISSUES!

TRANSMISION SLIPS IN DRIVE ON HILLS. IT ACTUALLY ROLLS BACKWARDS WHEN YOU TAKE YOUR FOOT OF THE BRAKE. EVEN WHEN THE TRANSMISION IS IN GEAR

I HAVE A 2010 GMC ACADIA. SEVERAL MONTHS AGO I RECEIVED THE GM SPECIAL COVERAGE EXTENDED WARRANT LETTER # 14329. AT THAT TIME, I HAD ALREADY NOTICED EXTREME DIFFICULTY IN TURNING THE WHEEL AT LOW RATES OF SPEED AND BRUSHED IT OFF AS PROBABLY NEEDING POWER STEERING FLUID I ALSO NOTICED A "WHINING" NOISE ALONG WITH THIS ACTION. I BEGAN TO WORRY AS THE MATTER KEPT WORSENING AND ALREADY STILL HAD TRAUMA FROM A PRIOR ACCIDENT IN 2010 WHICH LEFT ME TO PURCHASE THIS VEHICLE IN 2011 WHICH I THOUGHT WOULD BE A MORE SAFE STABLE VEHICLE FOR ME. UPON A FEW WEEKS LATER, WHILE TRYING TO MAKE A LEFT HAND TURN MANEUVER, THE STEERING WHEEL COMPLETELY "LOCKED" UP! LUCKILY, NO ONCOMING TRAFFIC WAS IN SIGHT, OTHERWISE, I WOULD HAVE BEEN UNABLE TO GET OUT OF THE WAY AS I WAS IN THE MIDDLE OF THE HIGHWAY! I IMMEDIATELY CONTACTED...

WE BOUGHT OUR 2010 ACADIA CERTIFIED USED WITH 60,000. WATER PUMP WENT OUT, NAVIGATIONAL SYSTEM STOP WORKING AND I NOTICED A HESITATION IN SHIFTING FROM TIME TO TIME BUT NOT CONSISTENT. THIS ALL RIGHT AFTER PURCHASING. THE DEALERSHIP FIXED WATER PUMP AS IT WAS STILL UNDER WARRANTY. I TOOK THE VEHICLE IN FOR A RECALL NOTICE AND ASKED IF THEY COULD FIND WHAT WAS WRONG WITH THE DVD/CD PLAYER, WAS TOLD I NEEDED A NEW RADIO. I ALSO TOLD THE MECHANIC I THOUGHT SOMETHING WAS WRONG WITH THE TRANSMISSION, THAT ISSUE WAS NOT ADDRESSED AS THOUGH I HADN'T MENTIONED IT. SO I WENT ONLINE TO SEE IF I COULD FIND A WAY TO FIX THE DVD/CD PLAYER MYSELF AND THAT'S WHEN I FOUND ALL THESE OTHER ACADIA OWNERS WITH THE SAME ISSUES...SO I THOUGHT IT BEST TO GET RID OF THIS TIME BOMB BEFORE ITS TOO LATE. WENT TO TRADE...

I HAVE TO KEEP ADDING POWER STEERING FLUID TO MY CAR. I HAVE BEEN TOLD THAT MY POWER TRAIN WILL NEED TO BE REPLACED AND THAT GMC IS AWARE OF THIS PROBLEM WITH THE ACADIA'S AND REFUSES TO FIX THE PROBLEM. *TR

TL* THE CONTACT OWNS A 2010 GMC ACADIA. WHILE MAKING A LEFT TURN AT AN UNKNOWN SPEED, THE VEHICLE JERKED VIOLENTLY AND THE STEERING WHEEL SEIZED. THE CONTACT HAD TO FORCEFULLY TURN THE STEERING WHEEL. THE DEALER WAS UNABLE TO DIAGNOSE THE CAUSE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED AND THE MANUFACTURER WAS NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 51,000.

AFTER MY 2010 ACADIA SAT IN A HOTEL PARKING LOT FOR 19 HOURS AFTER A DRIVE FROM SAN DIEGO TO KANSAS CITY, IT OVERHEATED THE MINUTE I STARTED IT. THE AIR STARTED BLOWING WARM AIR, IT STATED "POWERING DOWN ENGINE", & THE TEMP GAGE MAXED OUT. I IMMEDIATELY TURNED OFF THE CAR. AT LESS THAN 36K ON A CAR THAT HAS BEEN DRIVEN MINIMALLY, THIS SHOULD NEVER HAPPEN. AND NOW.... SINCE IT IS "OVER 3 YEARS OLD", IT'S PROBABLY NOT COVERED. $40K VEHICLE WITH 30K MILES ON IT AND ALREADY OVERHEATING? WE HAD OUR VEHICLE FOR THE LAST 2.5 YEARS IN HAWAII, SO IT'S NOT A CLIMATE PROBLEM. :-/ *TR

TL* THE CONTACT OWNS A 2010 GMC ARCADIA. THE CONTACT STATED THAT WHILE TRAVELING 20 MPH, THE POWER STEERING FAILED AND THERE WAS AN ABNORMAL NOISE COMING FROM THE VEHICLE. THE VEHICLE WAS TAKEN TO A PRIVATE MECHANIC WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION AND SYSTEM FLUID NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE AND CURRENT MILEAGE WAS 54,000.

THIS HAS HAPPENED SEVERAL TIMES SINCE I'VE BOUGHT THIS TRUCK LAST YEAR. RIGHT AFTER I BOUGHT IT, I HAD TO PAY OUT OF POCKET TO HAVE THE POWER STEERING BOX REPLACED ($1200.00) SINCE THEN, WHILE DRIVING MY STEERING GETS HARD TO TURN EITHER WAY AND THE ENGINE EVEN STOPPED RUNNING A FEW WEEKS AGO WHILE ON THE INTERSTATE, I HAD TO PULL OFF THE ROAD. THE TRUCK ALSO MAKES A POPPING SOUND WHILE TURNING TOO. SINCE I HAVE BOUGHT THE TRUCK, I HAVE HAD NOTHING BUT PROBLEMS, WITHIN 2 WEEKS OF BUYING IT, I HAD TRANSMISSION LEAK AND OIL LEAK THAT HAD TO BE FIXED. I WANT SO BAD TO GET OUT OF THIS TRUCK. I AM THE SOLE PROVIDER IN MY HOME, SINGLE MOTHER OF 3 KIDS AND THIS VEHICLE IS USED FOR OUR DAILY COMMUTES AND MY JOB. WHEN SLOWING DOWN TO COME TO A STOP THE TRUCK...

CAR ROLLS BACK WHEN ON A HILL WHILE IN DRIVE AT TRAFFIC LIGHT OR STOP SIGN. *TR

WHILE ACCELERATING ON THE ENTRANCE RAMP FOR CENTRAL EXPRESSWAY, HWY 75, IT BECAME VERY SLUGGISH, AND ALL OF A SUDDEN HAD NO PICK UP. I NEARLY GOT REAR ENDED BY A FAST TRUCK! SINCE APRIL OF 2011 I NOTICED THAT IT HAD NO PICK UP. THE PROBLEM SEEMED TO GO AWAY, WHEN I LEARNED TO NOT ACCELERATE TOO MUCH TO ENTER THE HIGHWAY, JUST GRADUALLY VS IN A HURRY. THEN TODAY, SEPT 2011, WHILE DRIVING AT APPRX 45 MPH ON A BUSY ROAD, THE CAR SEEMED TO PULL BACK, AND THE TRACTION LIGHT COMES ON, AND BEEPS AT ME. IT WAS A SUNNY, DRY DAY. I PULL OVER IN A PARKING LOT, TURN OFF THE ENGINE, TO GET SOMETHING OUT OF MY TRUNK, AND IT WOULD NOT OPEN - AND, NO, THE OVERRIDE BUTTON WAS NOT ON. WEIRD. I START THE CAR, AND THE PROBLEM GOES AWAY, AND I DRIVE...

MY 2010 GMC ACADIA SLT ROLLS BACKWARD ON INCLINES EVEN THOUGH THE TRANSMISSION IS IN DRIVE. I HAVE DRIVEN AUTOMATIC TRANSMISSION VEHICLES FOR YEARS AND IN MY EXPERIENCE THEY ARE NOT SUPPOSED TO ROLL BACKWARD IN DRIVE. IF ANYONE IS BEHIND THE VEHICLE WHEN THIS OCCURS THEY COULD VERY WELL BE CRUSHED. THE DEALERSHIP STATED THIS IS NORMAL BEHAVIOR, BUT THIS IS NOT AND THEY SHOULD BE REQUIRED TO FIX THE PROBLEM. *TR
