2017 GMC Acadia Power Train

UPON STOPPING VEHICLE AND SHIFTING IN TO PARK I GET A 'SHIFT TO PARK' NOTIFICATION ON THE DRIVERS' INFORMATION SCREEN ALTHOUGH THE VEHICLE IS IN PARK. SOMETIMES IT TAKES SEVERAL ATTEMPTS OF SHIFTING FROM AND BACK TO PARK FOR THE SCREEN TO CLEAR.

SHIFT TO PARK WHEN PUTTING THE CAR IN PARK, IT SAYS SHIFT TO PARK AND THE VEHICLE CONTINUES TO RUN AND HORN HONKS LETTING YOU KNOW YOU ARE EXITING THE CAR WITH IT RUNNING, AFTER PUTTING IT IN DRIVE, NEUTRAL, ETC AND SHIFTING IT BACK TO PARK, THE MESSAGE STILL DISPLAYS.

OUR ACADIA ON A 50% BASIS IS COMPLAINING TO THE DRIVER TO "SHIFT TO PARK". THIS IS EVEN THOUGH THE VEHICLE HAS BEEN SHIFTED TO PARK. TOOK TO THE DEALERSHIP TODAY AND THEY SAID THEY ORDERED THE PART BUT BECAUSE THIS IS A KNOWN ISSUE THERE IS NONE AVAILABLE RIGHT NOW AND NO IDEA WHEN THE PART WILL BE AVAILABLE.

WHEN SHIFTING VEHICLE INTO PARK, THE VEHICLE STILL SAYS SHIFT TO PARK AND WILL NOT TURN OFF.

TL* THE CONTACT OWNS A 2017 GMC ACADIA. THE CONTACT STATED THAT THE GEAR SHIFTER WOULD NOT REMAIN IN THE PARK POSITION AND THE VEHICLE WOULD NOT POWER OFF. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO NORMAN GALE BUICK GMC (1247 NJ-10, CEDAR KNOLLS, NJ 07927, (973) 975-4039) WHERE IT WAS DIAGNOSED THAT THE GEAR SHIFTER NEEDED TO BE REPLACED. THE DEALER STATED THAT THE PART WOULD NOT BE AVAILABLE UNTIL SEPTEMBER OF 2019. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS APPROXIMATELY 26,000.

UPON SHIFTING THE VEHICLE INTO PARK THE ONBOARD DISPLAY WILL NOT SHOW THE VEHICLE IN PARK. AFTER REVIEWING MULTIPLE FORUMS THIS IS A COMMON PROBLEM THAT COULD BE A SAFETY ISSUE IF THE VEHICLE IS NOT SHIFTING INTO PARK

SHIFT TO PARK ISSUE. WHEN YOU PUT THE VEHICLE IN PARK, THE VEHICLE DOES NOT RECOGNIZE THAT IT IS IN PARK AND DISPLAYS ON THE INFORMATION SCREEN TO SHIFT TO PARK. THE VEHICLE WILL NOT ALLOW YOU TO TURN IT OFF BECAUSE IT THINKS THE CAR IS NOT IN PARK WHEN IT ACTUALLY IS. THIS WAS FIXED UNDER WARRANTY FOR ME IN 2018 WITH 14K MILES (REPLACED SHIFTER ASSEMBLY) AND NOW I HAVE HAVING THE SAME ISSUE AT 39K MILES. GM NEEDS TO RECALL THESE VEHICLES AND HAVE THE OLD SHIFT ASSEMBLY (P/N 84159722) REPLACED WITH THE NEW SHIFT ASSEMBLY IT CREATED IN OCTOBER OF 2018 (P/N 13528228) WHEN MY VEHICLE WAS SERVICED AT 14K MILES, IT WAS REPLACED WITH THE OLD PART NUMBER 84159722 WHICH IS DEFECTIVE AS I AM HAVING THE SAME PROBLEM AGAIN AT 39K MILES. NOW MY VEHICLE IS OUT OF WARRANTY AND I AM GOING TO BE EXPECTED TO PAY $700 TO HAVE THE NEW SHIFT ASSEMBLY REPLACED. THIS SHOULD BE A RECALL BECAUSE IT IS A SAFETY ISSUE BECAUSE IT WILL NOT ALLOW PEOPLE TO TURN OFF THEIR VEHICLES ALL OF THE WAY, WHICH QUICKLY DRAINS BATTERY AND STRANDS THEM.

AFTER PARKING THE VEHICLE, SHIFTING INTO PARK AND TURNING OFF THE ENGINE, A WARNING MESSAGE APPEARS STATING TO SHIFT THE CAR INTO PARK. THE CAR IS IN PARK, BUT THERE MUST BE SOME TYPE OF SENSOR FAILURE. I AM PROHIBITED FROM COMPLETING SHUT DOWN OF THE VEHICLE UNTIL I CLEAR THE WARNING MESSAGE. WHEN THIS ISSUE FIRST AROSE, I COULD "JIGGLE" THE SHIFTER A BIT, AND THE MESSAGE WOULD CLEAR. NOW, ABOUT TWO WEEKS LATER, I NEED TO START THE CAR, MOVE THE SHIFTER BETWEEN GEARS, AND THEN BACK INTO PARK. AFTER 2 - 3 TIMES REPEATING THE PROCEDURE, THE WARNING MESSAGE USUALLY CLEARS. THE VEHICLE HAS BEEN TAKEN IN FOR SERVICE. A NEW SHIFTER HAS BEEN ORDERED. THE PART IS ON BACK ORDER.

WHEN I PUT MY CAR INTO PARK TO TURN OFF MY CAR, IT WOULD NOT TURN OFF AND SAID TO PUT CAR IN PARK. I HAVE TO WIGGLE THE SHIFTER, SOMETIMES SEVERAL TIMES. IT HAPPENED RIGHT BEFORE WHEN MY CAR WAS IN AROUND 35,000 MILES. THEY DIDN'T HAVE ANY APPOINTMENTS THAT WEEK. I HAD TO GO TO CALIFORNIA THE NEXT WEEK. I WENT IN YESTERDAY, SINCE IT WAS OVER 36,000 MILES. THEY SAID IT WAS NOT UNDER WARRANTY ANYMORE. I TOLD THEM THE SITUATION. SAID L HAD TO PAY $488.

WHEN YOU SHIFT INTO PARK, THE VEHICLE DOES NOT REGISTER AS BEING IN PARK. THERE IS AN INDICATOR ON THE GAUGE PANEL SAYING "SHIFT TO PARK." THIS IS A SAFETY ISSUE, THE ENGINE CANNOT BE TURNED OFF WHILE IN THIS CONDITION AND IT DOES NOT REGISTER THE TRANSMISSION AS BEING IN PARK. THIS HAPPENS EVERY TIME THE VEHICLE IS SHIFTED INTO PARK ONCE THE VEHICLE IS STOPPED.

WHEN PARKING THE VEHICLE, AFTER SHIFTING TO PARK, THE DASHBOARD DISPLAYS A WARNING SHIFT TO PARK AND WILL NOT ALLOW THE VEHICLE TO BE SHUT OFF. THE VEHICLE WAS STATIONARY ON A CITY STREET, IN OUR DRIVEWAY, AND ALSO IN A PARKING LOT. THIS PREVENTED ME FROM EXITING THE VEHICLE FOR ABOUT 10 MINUTES EACH TIME, WILL I CONTINUED TO RESTART THE CAR, SHIFT FROM PARK TO ANOTHER GEAR AND THEN RESHIFT INTO PARK.

WHEN PLACING VEHICLE IN PARK AND TURNING OFF IGNITION, THE MESSAGE APPEARS 'SHIFT TO PARK'. EVERYTHING IS STILL ON IN THE VEHICLE, LIGHTS RADIO ETC. SOMETIMES I CAN WIGGLE THE SHIFT CONTROLLER AND IT WILL DISAPPEAR OR SOMETIMES I HAVE TO TURN IGNITION BACK ON AND TRY AGAIN TO TURN OFF. SOMETIMES TAKES SEVERAL TIMES TO GET MESSAGE TO DISAPPEAR.

WHEN I PUT THE CAR IN PARK AND TRY TO SHUT OFF MY CAR, IT BEEPS AND TELLS ME THAT I HAVE TO SHIFT MY CAR INTO PARK. (ALTHOUGH MY CAR IS ALREADY PHYSICALLY IN PARK)THIS TAKES ME, AT TIMES, SEVERAL ATTEMPTS. SOMETIMES I CAN WIGGLE THE SHIFTER, OTHER TIMES I HAVE TO TURN MY CAR OFF AND ON AND SWITCH I TO DRIVE AND REVERSE SEVERAL TIMES BEFORE IT LETS ME SHUT OFF MY CAR PROPERLY SO I CAN EXIT. I JUST PURCHASED THIS CAR SEVERAL WEEKS AGO AND IT JUST STARTED. THIS ONLY HAPPENS WHEN I AM STOPPED AND TRYING TO EXIT MY CAR. IT HAS HAPPENED WHILE TRYING TO GO INTO WORK (IT MADE ME LATE!), WHEN I WAS OUT OF TOWN (4 ATTEMPTS JUST TO BE ABLE TO GET OUT!). ONE OF THESE TIMES I'M GOING TO LITERALLY BE STUCK TRYING TO GET MY CAR SHUT OFF. MY CONCERN IS THAT ALTHOUGH MY CAR IS PARKED, IT MAY NOT ACTUALLY BE "LOCKED" INTO PARK AND COULD POSSIBLY STILL BE IN NEUTRAL.

2017 GMC ACADIA DISPLAYS "SHIFT TO PARK" WHEN ALREADY IN PARK AND DOESN'T ALLOW THE VEHICLE TO TURN OFF THE ELECTRONICS. PROBLEM WAS SUPPOSEDLY FIXED UNDER WARRANTY WHEN I TOOK IT IN TO THE DEALER IN JULY OF 2018. NOW EXACTLY 1 YEAR LATER, NOW OUT OF WARRANTY, THE "SHIFT TO PARK" MESSAGE IS HAPPENING AGAIN AFTER THE CONTROLLER WAS REPLACED LAST YEAR TO FIX THE PROBLEM. NOW THAT CAR IS OUT OF WARRANTY, EVEN THOUGH ITS SUCH A COMMON COMPLAINT NOW THAT GMC IS AWARE OF, THE DEALER IS ASKING ME TO PAY OVER $500 TO FIX IT AGAIN. HOW DO I KNOW IT WILL FIX IT THIS TIME? THE LAST "FIX" ONLY LASTED A YEAR. GMC NEEDS TO ISSUE A RECALL AND FIX THEIR MANUFACTURING DEFECT.

WHEN CAR IS PLACED IN PARK, THE DASHBOARD DISPLAY SAYS THAT THE CAR MUST BE SHIFTED TO PARK, ALTHOUGH IT IS HAS BEEN PUT IN PARK. THE CAR MUST BE RESTARTED, AND RESHIFTED TO PARK, MULTIPLE TIMES. (AS MANY AS A DOZEN TIMES.) WHEN THE ERROR MESSAGE APPEARS THE ELECTRICAL COMPONENTS DO NOT SHUT DOWN. THE CAR CANNOT BE LOCKED. UNSURE WHETHER CAR IS/ IS NOT ACTUALLY IN PARK, OR WHETHER THERE IS A DANGER OF CAR ROLLING AWAY.

WHEN VEHICLE IS SHIFTED INTO PARK INFORMATION CENTER SAYS VEHICLE IS NOT IN PARK AND VEHICLE WILL NOT SHUT OFF. I HAVE TAKING THE VEHICLE INTO GMC SERVICE AND THEY SAID IT WAS OKAY TO DRIVE IT AND TAKE IT HOME. SINCE THEN WE HAVE HAD TO GET THE VEHICLE TOWED BACK TO THE SERVICE DEALERSHIP THAT SAID IT WAS OKAY TO DRIVE BECAUSE THE VEHICLE DIED SEVERAL TIMES AND WOULD NOT START. THERE IS A NATION WIDE PROBLEM WITH THIS MODEL ANT THE SHIFTING NOT STAYING IN PARK.

A "SHIFT TO PARK" MESSAGE SHOWS UP AFTER I HAVE ALREADY PUT MY VEHICLE IN PARK WHICH DOES NOT ALLOW ME TO TURN MY VEHICLE OFF COMPLETELY. I HAVE 53,500 MILES ON MY ACADIA AND HAD TO HAVE A NEW BATTERY PUT IN LAST WEEK. A GMC DEALERSHIP STATES THE PART TO FIX THE SHIFT LEVER IS ON BACK ORDER BUT THAT THEY HAVE HEARD THIS IS A COMMON ISSUE WITH THE 2017 ACADIA. IT IS FRUSTRATING THAT GMC IS AWARE THERE IS AN ISSUE AND THAT THERE HAS BEEN A LAWSUIT FILED REGARDING THIS HOWEVER THERE HAS NOT BEEN A RECALL ISSUED.

WHEN THE CAR IS PARKED ON A FLAT SURFACE (INSIDE THE GARAGE, PARKING GARAGE, PARKING LOT), THE CAR WILL DISPLAY "SHIFT TO PARK" WHEN IT IS ALREADY IN PARK. THE ACCESSORIES STAY ON UNTIL THE DRIVER IS ABLE TO GET THE CAR'S COMPUTER TO NOTICE THE CAR IS IN PARK.

TL* THE CONTACT OWNS A 2017 GMC ACADIA. WHILE THE VEHICLE WAS ENGAGED IN PARK WITH THE ENGINE RUNNING, IT INADVERTENTLY ROLLED AWAY. AS A RESULT, THE OCCUPANT WAS STRUCK BY THE DOOR AND THE VEHICLE RAN OVER THE OCCUPANT'S FOOT. MEDICAL ATTENTION WAS REQUIRED. THE VEHICLE CONTINUED TO ROLL AWAY AND REAR ENDED ANOTHER VEHICLE. A POLICE REPORT WAS NOT FILED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS AWAITING DIAGNOSTIC TESTING AND REPAIRS. THE DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 3,002. THE VIN WAS NOT AVAILABLE.

WHEN THE VEHICLE IS IN PARK AND YOU TRY TO TURN IT OFF WITH THE START/STOP BUTTON AN ON DASH ERROR CODE OF "SHIFT TO PARK" APPEARS EVEN THOUGH THE VEHICLE IS CLEARLY IN PARK. YOU ARE NOT ABLE TO TURN THE VEHICLE OFF. I TOOK THE VEHICLE IN FOR SERVICE ON 6/4/18 AND WAS TOLD THAT GM IS AWARE OF THE ISSUE HOWEVER THEIR ENGINEERS HAVE NOT FOUND A SOLUTION. THIS CURRENTLY IS FORCING ME RESTART THE ENGINE, PUT MY CAR IN REVERSE, SHIFT BACK IN DRIVE, TRY RE PARKING AND TURNING OFF AGAIN REPEATING THE PROCESS UNTIL IT EVENTUALLY TURNS OFF. I DO NOT KNOW IF MY CAR IS TRULY IN GEAR OR NOT. I'M AFRAID THAT IT MIGHT CAUSE A DANGEROUS SITUATION.

A MESSAGE SHIFT TO PARK KEPT APPEARING WHEN THE CAR WAS IN PARK AND SHUT OFF. THEN I PUT THE CAR IN REVERSE AND THE ENTIRE CARE LOCKED UP. (A MESSAGE FROM GMC -GENERAL MOTORS LLC (GM) IS RECALLING CERTAIN 2018 CHEVROLET EQUINOX AND GMC TERRAIN VEHICLES AND 2017-2018 GMC ACADIA VEHICLES. THE RIGHT FRONT INTERMEDIATE DRIVESHAFT MAY FRACTURE AND SEPARATE WHILE DRIVING.)

THE VEHICLE SHIFTS VERY HARSHLY BETWEEN SECOND AND THIRD GEARS WHEN ACCELERATING. SOMETIMES IT IS SO HARSH THAT IT SLAMS YOU BACK IN THE SEAT. THE DEALER SAYS THAT IT IS "NORMAL". IT BEGAN AFTER OWNING THE VEHICLE FOR ONE FULL YEAR.

HARMONIC VIBRATION AT AROUND 1500 RPM WHILE HOLDING SPEED ANY GEAR OR MPH

MY 2017 GMC ACADIS 6 CYLINDER AWD HAS EXCESSIVE VIBRATIONS THAT OCCUR AT 1400-1600 RPM AND AT VARIOUS SPEEDS.IT SEEMS LIKE THE TRANSMISSION REFUSES TO SHIFT AND IT LASTS FOR UP TO A QUARTER MILE.VIBRATION IS MOST PRONOUNCED AT SPEEDS OF 55-60 MPH THE DEALER DIAGNOSIS SAYS IT IS FUNCTIONING NORMAL. THE STRUTS WERE REPLACE AT1390 MILES AND MOTOR MOUNTS ADJUSTED, PROBLEM REMAINS, AUTO BROUGHT TO DEALER FOR RECALL AS PER BULLETIN 17109 BUT IT STILL VIBRATES EXCESSIVELY. THE LEAD MECHANIC AT THE DEALERSHIP SAID THE AUTO ADJUSTS TO THE DRIVER AND SAID THE VIBRATIONS WILL STOP AT ABOUT 2500 MILES. THE CAR NOW HAS 2900 MILES AND IT STILL FEELS LIKE THE TRANSMISSION IS GOING TO FAIL. THE VIBRATION IS UNCOMFORTABLE AND ALTHOUGH THE DEALERSHIP SAID THE CAR IS SAFE IT DOES NOT FEEL SO.IT SEEMS IMPOSSIBLE FOR A VEHICLE TO BE FUNCTIONING PROPERLY WITH THIS CONTINUAL ERRATIC VIBRATIONS.

WHEN THE VEHICLE AUTOMATICALLY GOES INTO V4 MODE THERE IS A VIBRATION INSIDE THE CABIN. THE VIBRATION ALSO SOUNDS LIKE A BOOM NOISE INSIDE THE CABIN AND THE VEHICLE SHAKES WHILE DRIVING. THE PROBLEM SEEMS TO OCCUR AT 1500-1700 RPMS AND WILL CONTINUE UNTIL YOU ACCELERATE AND MAKE THE VEHICLE GO BACK INTO V6 MODE. DEALER ATTEMPTED TO FIX THE PROBLEM ON 2 OCCASIONS BUT WAS UNABLE TO. DEALER ACKNOWLEDGED THE PROBLEM AND CATEGORIZED IT AS A VIBRATION, DRONE, FLUTTER OR BOOM NOISE INSIDE THE CABIN WHILE VEHICLE IS IN AFM V4 MODE. PROBLEM HAS NOT BEEN FIXED.
