2017 GMC Acadia

SHIFT TO PARK STAYS ON WHEN PLACING MY VEHICLE INTO PARK. THIS DOES NOT ALLOW THE ELECTRONICS TO SHUT OFF INDEFINITELY RESULTING IN A DEAD BATTERY. GMC HAS STATED THAT THIS IS NOT A RECALL AND THAT BECAUSE I AM OUT OF MY WARRANTY THIS IS NOT COVERED. AFTER READING MULTIPLE FORUMS THERE ARE HUNDRED OF PEOPLE WITH THIS SAME ISSUE FROM 100MILES TO 60K+ AND GM HAS REFUSED TO MAKE THIS A RECALL. SOMEONE DID STATE THAT THEY GOT THEIR SHIFT ASSEMBLY REPLACED AND IT FIXED THE PROBLEM. VERY DISAPPOINTED WITH GM AND NOT STANDING BEHIND AN ISSUE THAT IS CLEARLY A DEFECT FROM THE MANUFACTURE. THEY ALSO ARE HAVING THE SAME ISSUES WITH CADILLAC STEMMING FORM THEIR TENNESSEE PLANT. BUYERS BEWARE!

VEHICLE DISPLAYS "ACTION REQUIRED - SHIFT TO PARK" IN THE DASHBOARD INFORMATION CENTER WHEN THE GEAR SHIFT IS PUT INTO PARK AND THE IGNITION PUSH BUTTON IS PUSHED TO TURN THE VEHICLE OFF. THE ALARM SOUNDS REPEATEDLY AND THE AUXILIARY POWER STAYS ON. IF THE VEHICLE IS EXITED ALARMS SOUND AS IF THE KEY FOB WERE LEFT IN THE VEHICLE. IN ADDITION, THE AUXILIARY POWER STAYS ON (INCLUDING THE HEADLIGHTS IF IN AUTO MODE) INDEFINITELY. MY DEALERSHIP IS UNABLE TO FIX THIS PROBLEM FOR NEARLY TWO MONTHS AND HAS OTHER CUSTOMERS WITH THE SAME PROBLEM. GMC CUSTOMER ASSISTANCE HAS PROVIDED NO HELP.

THIS ISSUE HAS HAPPENED 3 TIMES NOW AND IS BECOMING A SAFETY CONCERN FOR MY FAMILY AND I AND FOR OTHERS ON THE ROAD. I PURCHASED THE CAR BRAND NEW IN MAY 2017 AND THE ISSUE OCCURED FOR THE FIRST TIME ON OCTOBER 02, 2017. SECOND TIME WAS FEBRUARY 15, 2018 AND THE THIRD TIME HAPPENED AROUND EARLY APRIL 2018. WHILE DRIVING AT A SLOW SPEED (ENTERING A PARKING LOT, IN THE MIDDLE OF AN INTERSECTION WHEN I WAS ABOUT TO MAKE A LEFT TURN ON A GREEN LIGHT, AND WHILE DRIVING IN A PARKING LOT AFTER GETTING GAS) THE CAR MADE A GRINDING/CLUNKING SOUND AND WAS BROUGHT TO A VERY ABRUPT STOP. I TRIED TO PRESS THE GAS BUT THE CAR WOULD NOT MOVE. I CHANGED THE GEAR FROM DRIVE TO PARK AND THEN DRIVE AGAIN AND WOULD STILL NOT MOVE. I TURNED THE CAR OFF AND THEN BACK ON AND STILL NOTHING. I ENDED UP FIGURING IT OUT BY PRESSING THE PARKING BREAK BUTTON 1-2 TIMES AND WAS THEN ABLE TO PROCEED TO DRIVE. IT SEEMS AS THOUGH SOMETHING MAY HAVE TRIGGERED THE PARKING BRAKE BUT WHILE I WAS IN DRIVE AND WHILE THE VEHICLE WAS MOVING. I WAS ALMOST REAR ENDED WHEN THIS HAPPENED IN THE INTERSECTION AND ALSO DURING THE TIME I WAS UNABLE TO MOVE IN THE INTERSECTION, MY LIGHT HAD CHANGED TO YELLOW AND THEN RED AND ONCOMING TRAFFIC WAS HONKING BECAUSE THEY COULD NOT GO ON THEIR GREEN LIGHT DUE TO ME BEING STOPPED IN THE INTERSECTION. IT WAS VERY SCARY AND DANGEROUS AS IT ALMOST CAUSED AN ACCIDENT 2 OUT OF THE 3 TIMES IT HAS HAPPENED. I TOLD SERVICE DEPT AT THE DEALERSHIP ABOUT IT TWICE. THEY HAVE "LOOKED INTO IT" ONE TIME BUT SINCE THEY WERE NOT ABLE TO REPLICATE THE ISSUE (OBVIOUSLY), THERE IS NOTHING THEY CAN DO. I AM CONCERNED ABOUT MY FAMILIES SAFETY IF THIS CONTINUES TO HAPPEN.

WE BOUGHT THIS VEHICLE IN LATE JANUARY 2018. THE CAR WAS A NEW 2017 GMC ACADIA. WE HAD THE CAR A FEW DAYS WHEN MY WIFE SAID THAT SHE COULD NOT GET THE HORN TO WORK. SHE SAID SHE LOOKED AT THE MANUAL AND FOUND WHERE TO PUSH BUT NOTHING. I TRIED AND COULD NOT GET THE HORN TO WORK EITHER I CALLED TO AND MADE AN APPOINTMENT FOR THE DEALER SERVICE TO LOOK AT THE CAR. THEY INFORMED ME THAT IT NEEDED A NEW CONTACT. TOLD ME THEY WOULD CALL WHEN THE PART COMES IN. I STILL HAVEN'T HEAD FROM THEM AND CALLED A COUPLE OF TIME AND WAS TOLD AGAIN, WE'LL CALL AS SOON AS THE PART COMES IN. I BELIEVE THIS IS A BIG SAFETY PROBLEM AS SEVERAL TIME WE NEED THE HORN AND COULD NOT GET IT TO WORK.

HORN IS EXTREMELY DIFFICULT TO SOUND. IT TAKES STRONG PRESSURE ON ONLY ONE AREA OF THE SURFACE TO SOUND. MY WIFE HAS NEVER BEEN ABLE TO DO IT. WOULD BE ALMOST IMPOSSIBLE TO SOUND IN AN EMERGENCY. THERE ARE MANY INSTANCES OF THIS ISSUE ON LINE. ATTATCHED IS THE DEALERS STATEMENT. BOTH THE DEALER AND GMC REP SAY IT IS WORKING AS DESIGNED. IT HAS BEEN LIKE THIS SINCE NEW. (NOV. 2017)

HIGH HORN EFFORT - HORN DOES NOT ACTIVATE WHEN PRESSED ON. DRIVER HAS BEEN UNABLE TO NOTIFY OTHER CARS COMING INTO THEIR LANE. CONCERNED THAT THEY WILL BE UNABLE TO AVOID AN ACCIDENT. TOOK DELIVERY OF VEHICLE ON 01SEP2017 WITH THIS AS A KNOWN ISSUE. HAVE NOT HAD ANY RESOLUTION UNTIL VEHICLE WENT INTO SERVICE AROUND 09JAN18. BULLETIN ISSUED TO REPLACE WIRE HARNESS. THIS NEW WIRE HARNESS DID NOT IMPROVE THE CONDITION AT ALL - MAY EVEN BE WORSE THAN BEFORE. THIS IS A SAFETY ISSUE - GM NEEDS TO ADDRESS THIS IMMEDIATELY. THIS IS EITHER DUE TO THE DRIVER AIRBAG CUSHION PACK HEIGHT OR WIRE HARNESS LIMITING HORN TRAVEL.

I WAS DRIVING FOR APPROXIMATELY 20 MILES ON A HIGHWAY WITH MY WINDSHIELD WIPERS IN THE INTERMITTENT POSTION. THERE WAS A LIGHT SNOW COMING DOWN. THE WIPERS WORKED UP TO THIS TIME. THE DRIVER SIDE WINDSHIELD WIPER STOPPED WORKING. THIS AFFECTED VIABILITY DRAMATICALLY. IT WOULD HAVE BEEN WORSE WITH HEAVIER SNOW. I TOOK IT TO THE DEALER AND THEY FOUND THE SCREW HAD LOOSENED AND THE WIPER MOTOR AND WINDSHIELD WIPER WERE DISCONNECTED.
