I HAD JUST PICKED UP 250 PIECES OF CHICKEN FROM GIANT EAGLE TO FEED THE HOMELESS AT THE YWCA AND PLACED THE BOXES IN THE BACK OF MY VEHICLE. AS I DROVE DOWN THE STREET THE WINDOW BEGAN TO FOG SO I TURNED ON THE DEFROST. WITHIN MINUTES OF TURNING ON THE DEFROST, THE WINDOW SHATTERED INTO PIECES. I ENDED UP HAVING TO THROW AWAY OVER 100 PIECES OF CHICKEN, BUT LUCKILY NO ONE WAS HURT. I HAVE CALLED THE DEALERSHIP AND FILED A COMPLAINT WITH THE CORPORATE OFFICE, BUT THEY SAY THEY CANNOT ASSIST. AFTER SPEAKING WITH CANDICE AT GMC, @866-790-3600 EXT 5923331, I WAS TOLD THAT THE EXTENDED WARRANTY I PURCHASED DOES NOT COVER GLASS. I BOUGH THE CAR USED ALMOST A YEAR AGO, PURCHASED THE EXTENDED WARRANTY TO REPLACE THE BUMPER TO BUMPER COVERAGE, SO WHY DOESN'T IT COVER GLASS? WHAT IS EVEN MORE FRIGHTENING TO ME IS HOW DOES A WINDOW JUST SHATTER? THIS IS A DEFECT THAT NEEDS TO BE ADDRESS AND THIS SHOULD BE COVERED BY GMC. I HAVE RESEARCHED AND FOUND THAT THIS HAS HAPPENED IN OTHER GMC VEHICLES AND PERHAPS THIS NEEDS TO BE A CLASS ACTION LAW SUIT BEFORE IT WILL BE PROPERLY ADDRESSED.

WHEN STOPED ON A HILL THE TRANSMISSION GOES INTO NEUTRAL & THE CAR ROLLS BACKWARD DOWN HILL WHEN YOU TAKE YOUR FOOT OFF THE BRAKE TO TAKE OFF AGAIN. TOOK IT TO A GMC DEALER &A THEY TOLD US THEY DROVE A 2013 ACADIA & A 2015 BUICK WITH THE SAME DRIVE TRAIN AS OURS & BOTH CARS ROLLED BACK LIKE OURS SO THEY DETERMINED IT WAS "NORMAL"! I WAS A FORD TECH FOR 32 YEARS AND NEVER RAN INTO A PROBLEM LIKE THIS, I DO NOT FEEL IT'S NORMAL. WHAT WILL HAPPEN IF WE ROLL BACK INTO ANOTHER CAR OR HIT SOMEONE WHO WALKS BEHIND THE CAR?? THIS HAS HAPPENED COMING OUT OF PARKING LOTS NEAR OUR HOUSE, & IT HAPPENED ON I 40 WHEN WE WERE GOING TO TEXAS FOR VACATION THERE WAS AN ACCIDENT AHEAD OF US & WE WERE STUCK IN THE HILLS OUTSIDE WILLIAMS ARIZ I HAD TO DRIVE WITH ONE FOOT ON THE BRAKE & THE OTHER ON THE GAS TO KEEP FROM ROLLING BACK IN HEAVY TRAFFIC. THANK YOU FOR YOUR TIME

"TAKATA RECALL" MESSAGE AIR BAG COMES ON. I TOOK MY CAR TO THE DEALERSHIP AND THEY SAID IT WAS CAUSED BY THE DRIVER SIDE AIRBAG CONNECTOR HAD HIGH RESISTANCE (CODE B001E-0D). DEALERSHIP REMOVED AIRBAG CONNECTORS, TRACED WIRED, AND SPLICED WIRES TOGETHER. THIS IS THE SAME ISSUE I READ ABOUT FOR THE 2013 ACADIA MODELS. MY ACADIA IS A 2014 MODEL AND WE HAD TO PAY FOR THIS REPAIR OUT OF POCKET. I FEEL THAT WE SHOULD BE RE-REIMBURSED FOR THIS REPAIR, IT WAS VERY COSTLY FOR THE DEALERSHIP TO JUST CUT AND SPLICE WIRES.

THE FIRST DEALER NOTICED A LEAK, REPLACED A LINE, RECHARGED THE SYSTEM, BUT THE FAILURE CONTINUED MONTHS LATER. THE VEHICLE WAS TAKEN BACK TO THE FIRST DEALER WHO REPEATED THE SAME SOLUTION, WHICH PROVIDED NO REMEDY AS THE HOT AIR CONTINUED TO EMIT FROM THE AIR CONDITIONER. THE VEHICLE WAS TAKEN TO THE SECOND DEALER FOR FURTHER DIAGNOSTIC TESTING. THE CONTACT WAS UNCERTAIN IF THE MANUFACTURER WOULD BE ABLE TO PROVIDE A SOLUTION TO THE DEALER TO REPAIR.

WHILE DRIVING TO WORK THIS MORNING GOING AROUND THE CURVE THE VEHICLE LOST POWER. THE STABILITY, TRACTION CONTROL AND ENGINE LIGHT ALL CAME ON. I HAD TO MANEUVER MY VEHICLE OOUT OF HARMS WAY TO ENSURE MY DAUGHTER WAS SAFE. MY SPEED WENT FROM 55 TO 20 IN LESS THAN 10 SECONDS. LOSS OF POWER ON ANY VEHICLE IS SCARY BUT THIS IS IS VERY SERIOUS AND SOMETHING NEED TO DONE TO RECTIFY THESE VEHICLE ISSUES. PLEASE TAKE A LOOK INTO THIS ISSUE BEFORE SOME IS INJURE OR KILLED. THANK YOU.

THE 2014 GMC ACADIA SLT1 HAS THE LATCH SAFETY SYSTEM ON CAPTAINS CHAIRS ONLY, NOT ON THE 3RD ROW SEATING. IF YOU HAVE TWO CAR SEATS OCCUPYING 2ND ROW CAPTAINS CHAIRS YOU CAN NOT FOLD THE SEATS TO ACCESS THE THIRD ROW. THIS IS A SURPRISING DESIGN FLAW; CONSIDERING THE VEHICLE TARGETS FAMILIES.

IN 2016, A GMC DEALER SOLD ME, AND ATTEMPTED TO INSTALL, AN UPDATE FOR MY "INFOTAINMENT" GPS SYSTEM ON MY 2014 ACADIA DENALI. THE RESULT WAS LOSS OF VEHICLE USAGE ON THREE SEPARATE SERVICE DATES TOTALING 15 DAYS. THE REASON FOR SEVERAL SERVICE DATES WAS CAUSED BY THE GPS SOFTWARE AND THE INABILITY TO NOT ONLY DOWNLOAD THE GPS UPDATE TO THE "INFOTAINMENT" SYSTEM, BUT IN THE PROCESS, IT CAUSED DAMAGE TO THE ENTIRE "INFOTAINMENT" SYSTEM; INCLUDING, NAVIGATION FEATURES, THE HANDS-FREE USE OF ONES' CELL PHONE, VOICE COMMANDS, AND RADIO/ENTERTAINMENT SYSTEMS, AS WELL. THE ELECTRONIC DAMAGE REQUIRED THE REPEATED REPLACEMENT (3) OF THE ENTIRE "INFOTAINMENT" SYSTEM WHEN GMC DETERMINED THAT THE GPS UPDATE SOFTWARE WAS THE PROBLEM. WHILE ONE WOULD EXPECT GMC TO IMMEDIATELY CORRECT THE PROBLEM, IT HAS NOW BEEN THREE YEARS SINCE THE VEHICLE WAS MANUFACTURED WITH A GPS SYSTEM THAT CANNOT BE UPDATED. TO DATE, GMC HAS BEEN UNABLE TO PROVIDE A GPS UPDATE; ONLY EMAILS APOLOGIZING FOR THE INCONVENIENCE WITH UNRELIABLE MOVING TARGET DATES STATING WHEN THE UPDATE WILL BE AVAILABLE. IT IS IRONIC THAT I MUST RESORT TO THE USE OF A DEPENDABLE, READILY UPDATED $300 PORTABLE GARMIN GPS FOR MY EXTENSIVE TRAVELS AROUND THE COUNTRY. FOR THOSE OF US THAT MUST TRAVEL, I SUGGEST A ALTERNATE MAKE/MODEL VEHICLE THAT HAS A MORE RESPONSIVE MANUFACTURER, AND SERVICEABLE VEHICLE ACCESSORY SYSTEMS.

ON MARCH 15, 2017 OUR 2014 GMC ACADIA SPONTANEOUSLY LOST STEERING POWER ASSIST AS I WAS MAKING A TURN AT AROUND 10 MILES PER HOUR. THE VEHICLE REGAINED POWER ASSIST 15 TO 20 SECONDS LATER. FOR THE NEXT SEVERAL MILES, IT APPEARED TO LOSE THE POWER ASSIST ONLY WHEN AT LOW IDLE AND OTHERWISE DROVE FINE. I DID SOME RESEARCH ON-LINE AND THIS PROBLEM APPEARS TO BE SOMEWHAT COMMON FOR THIS MAKE AND YEAR BUT I CANNOT FIND ANY RECALLS FOR IT.

I WAS DRIVING ON THE FREEWAY WITH MY 4 CHILDREN IN THE CAR. AS I WAS EXITING THE FREEWAY I SUDDENLY LOST ALL ABILITY TO STEER MY CAR. I WAS ALMOST HIT BY A BIG RIG BECAUSE I DID NOT KNOW WHAT WAS HAPPENING AND NO INDICATOR LIGHT WAS DISPLAYED ON MY DASHBOARD. THE CAR WAS ALMOST IMPOSSIBLE TO STEER AT SLOWER SPEEDS. I WAS PUT IN AN EXTREMELY DANGEROUS SITUATION. MY CAR ONLY HAS 45,000 MILES ON IT. THE DEALERSHIP SAYS MY WARRANTY IS ONLY GOOD FOR 36,000 MILES. RESEARCH HAS SHOWN THIS IS A VERY COMMON DEFECT WITH GMC ACADIA VEHICLES AND THEY HAVE NOT ISSUED A RECALL AND THE PROBLEM SEEMS TO OCCUR JUST AFTER THEIR STANDARD WARRANTY ENDS. THE STEERING PUMP IS DEFECTIVE AND THE COST TO FIX IS OVER $2,000. *TR
