WE PURCHASED A 2017 ACADIA AWD SLT ON DECEMBER 28, 2017. THERE WAS A RECALL ON GM BULLETIN #19-NA-206 FOR (SHIFT TO PARK) ISSUE. DEALER MICHAEL HOHL GMC 3700 S CARSON ST, CARSON CITY, NV 89701 ORDERED PART BUT WAS NOT INSTALLED UNTIL 1/13/20. DAY AFTER REPAIRS, FUELED CAR AND GAS GAUGE WOULD SHOW THREE QUARTERS FULL. THE FUEL RANGE ALSO BOUNCES UP AND DOWN AND IS NOT ACCURATE. IS THIS A GM RECALL ISSUE? MY CAR IS NOW OUT OF THE BUMPER TO BUMPER WARRANTY TO REPAIR THIS GAS GAUGE PROBLEM. WE ARE CONCERNED THAT WE MIGHT RUN OUT OF FUEL DUE TO FAULTY GAS GAUGE READING OR WAS THIS A PROBLEM CREATED BY R/R IN-LINE SHIFTER WIRE HARNESS JUMPER. CAR WAS AT DEALER FOR REPAIR (IN WARRANTY) @ 27,762 UNDER MILEAGE AND IS NOW OUT OF WARRANTY DUE TO THREE YEAR TIME SPAN. NOW @27,784 MILES.

CAR GIVES A "ACTION REQUIRED, SHIFT TO PARK" AND DOES NOT TURN OFF ALTHOUGH YOU HAVE PUT THE CAR IN PARK. YOU HAVE TO PUT THE CAR INTO REVERSE OR DRIVE AND MOVE IT BACK TO PARK MULTIPLE TIMES BEFORE IT SENSES IT IS IN PARK AND BEFORE IT WILL LET YOU TURN OFF THE VEHICLE. THE CAR WAS STATIONARY EVERY TIME THIS HAPPENED IN A PARKING SPOT.

NHTSA ODI 11300759

WITH MY VEHICLE STATIONARY AND SHIFTER IN THE PARK POSITION, I TURN MY CAR OFF AND THE VEHICLE TURNS OFF BUT THE INSTRUMENT CLUSTER SAYS "ACTION REQUIRED - SHIFT TO PARK". THIS MESSAGE ALSO DOES NOT ALLOW THE DAY TIME RUNNING LIGHTS TO TURN OFF AND IF THE LIGHTS DON'T TURN OFF THE BATTERY DRAINS IF PARKED FOR LONG STRETCHES. I HAVE TO TURN THE CAR ON/OFF SEVERAL TIMES BEFORE IT ENGAGES AND THE MESSAGE DISAPPEARS.

WHEN THE CAR IS SHIFTED FROM A DRIVING GEAR OR NEUTRAL INTO PARK, SOMETIMES THE CAR WILL NOT REGISTER THAT IT HAS ACTUALLY SHIFTED INTO PARK. A WARNING SHOWS UP ON THE DASH THAT SAYS "ACTION REQUIRED, SHIFT TO PARK" EVEN THOUGH IT IS IN PARK. THE CAR WILL NOT TURN OFF DURING THIS WARNING, SO YOU HAVE TO SHIFT IT BACK AND FORTH FROM DRIVE TO PARK UNTIL IT FINALLY REGISTERS PARK. SOMETIMES IT HAPPENS THE NEXT TRY, SOMETIMES IT WILL TAKE 50. THERE HAVE BEEN TWO OCCASIONS WHEN ATTEMPTING TO PARK ON A SLOPE THAT THE CAR STARTED TO ROLL, ONLY A FOOT OR TWO, BUT THEN THE EMERGENCY BRAKE AUTOMATICALLY TURNED ON THE BRING THE CAR TO A STOP. THE CAR HAS BEEN IN FOR SERVICE MULTIPLE TIMES AND THEY HAVE BEEN UNABLE TO FIND A FIX AT THIS TIME.

THE VEHICLE HAS HAD ONGOING ISSUES SINCE IT WAS PURCHASED IN JUNE OF 2017. THE 'SHIFT TO PARK' PROBLEM HAD TO BE FIXED TWICE, THE EMERGENCY BRAKING SYSTEM ENGAGES ITSELF FOR NO APPARENT REASON WHICH HAS ALMOST CAUSED SEVERAL ACCIDENTS, THE HORN DOES NOT WORK WHEN NEEDED IN EMERGENCY SITUATIONS, THE HEADLIGHTS ARE SO DIM IT'S DANGEROUS, THE BATTERY HAS DRAINED AND LEFT MY WIFE STRANDED 4 TIMES, AND THE VEHICLE HAS A VERY ROUGH IDLE AND IT ALMOST STALLS OUT. I ATTEMPTED TO WORK WITH GM TO HAVE THEM TAKE THE CAR BACK EARLY (LEASE) AND THE REQUEST WAS RECENTLY DENIED. THIS IS MY 3RD ACADIA AND IT BY FAR IS THE MOST DANGEROUS CAR I HAVE EVER DRIVEN. I AM NOW READING ABOUT A FUEL PUMP PROBLEM THAT COULD CAUSE THE VEHICLE TO CATCH ON FIRE, A DRIVESHAFT THAT MAY SEPARATE WHILE DRIVING, AND A FAULTY BRAKING SYSTEM THAT COULD CAUSE THE VEHICLE TO LOSE ALL BRAKING CAPABILITY. I DO NOT FEEL SAFE HAVING MY FAMILY IN THIS CAR AND I AM REQUESTING YOUR ASSISTANCE TO HELP ME WORK WITH GM ON A RESOLUTION. I ENTERED THE DATE THAT THE VEHICLE FIRST STARTED TO HAVE ISSUES, THERE HAVE BEEN OVER 20 INCIDENTS OVER A 2.5 YEAR PERIOD CAUSING A SAFETY ISSUE OR LEAVING MY WIFE AND CHILDREN STRANDED.

2017 GMC ACADIA WOULD ISSUE A WARNING SAYING VEHICLE FAILED TO SHIFT TO PARK EVEN THOUGH THE VEHICLE WAS IN PARK. THIS VEHICLE DEFECT IS KNOWN BY GMC AND THEIR DEALERSHIPS. A LAWSUIT IS CURRENTLY PENDING REGARDING THIS ISSUE. GMC HAS FAILED TO ISSUE A RECALL AND HAS FAILED TO RESOLVE THE ISSUE. WE TOOK OUR VEHICLE TO THE LOCAL GMC DEALERSHIP AUGUST 2018 DUE TO THE ISSUE. THE ISSUE STARTED AGAIN IN NOVEMBER 2019. WHEN WE CALLED ABOUT IT, THEY SAID THE PRIOR WORK WASN'T COVERED AND WE WOULD HAVE TO PAY TO HAVE THE "KNOWN DEFECT" REPAIRED AGAIN.

VEHICLE WHEN SHIFT TO PARK WOULD INDICATE THE SHIFT WAS NOT IN PARK. WHEN I GOT THE VEHICLE NEW IS WHEN IT STARTED. I HAVE PUT UP WITH IT BY PRESSING HARD ON THE GEAR SHIFT AND CHECKING IT BEFORE TURNING THE CAR OFF.

THE VEHICLE STATES TO 'SHIFT TO PARK' BUT THE VEHICLE IS IN PARK ALREADY. THE VEHICLE WILL NOT TURN OFF AND KEEPS THE BATTERY RUNNING. I MUST START UP THE CAR AND SHIFT IT TO DRIVE, THEN PACK TO PARK MULTIPLE TIMES BEFORE THE CAR RECOGNIZES IT IS IN PARK. THIS HAPPENS EVERY TIME, BUT THE AMOUNT OF TIME IT TAKES TO TURN ON AND OFF TO REACH 'PARK' IS RANDOM.

NHTSA ODI 11288529

"SHIFT TO PARK" ALERT APPEARS WHEN CAR IS IN "PARK" AND ATTEMPTING TO SHUT ENGINE OFF. ELECTRICAL SYSTEM STAYS ON WITH BELL CHIMING UNTIL I CAN RESTART CAR AND RE-SHIFT AGAIN INTO "PARK". THIS MAY HAVE TO BE DONE MULTIPLE TIMES BEFORE ALERT NO LONGER APPEARS. DOES NOT HAPPEN EVERY TIME WHEN ATTEMPTING TO SHUT OFF ENGINE, BUT WHEN IT DOES USUALLY REQUIRES MULTIPLE RESTARTING/RE-SHIFTING TO GET ALERT TURNED OFF.

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.

OCT 23, 2019 WE WERE SUPPOSED TO BRING OUR CAR FOR A SERVICE BECAUSE THE CHECK ENGINE IS ON BUT BEFORE WE EVEN GET TO THE DEALER THE CAR WON'T START. WE HAVE TO CALL FOR A TOWING COMPANY. WHEN WE GET THERE THEY SAID THEY DON'T KNOW WHAT'S WRONG. WE CALLED GMC COMPLAINT BEFORE WE GOT AN ANSWER WITH THE DEALER ON OCT 30 THEY SAID ITS A FUEL PUMP RECALL. SINCE THEN WE HAVEN'T HEARD FROM THEM. IT WILL 6 WEEKS THIS WEEK. WE JUST BOUGHT THIS CAR AS CERTIFIED PRE OWNED LAST APRIL 2019 NOW WE CANT'T USE IT AND NO UPDATES AT ALL. WE DON'T KNOW WHEN WILL HAVE OUR CAR BACK.

NHTSA ODI 11286478

WHEN THE CAR IS SHIFTED INTO PARK, IT OFTEN DOES NOT SHOW THAT IT IS IN PARK. IT WILL ROLL, THE LIGHTS WILL NOT GO OFF, DOORS WILL NOT LOCK. TO GET IT TO WORK, YOU MUST RESTART THE CAR AND MOVE THE SHIFTER IN AND OUT OF THE PARK POSITION. WHILE YOU ARE DOING THIS THE CAR WILL CONTINUE TO ROLL WITH THE BRAKES DEPRESSED. THE SERVICE WRITER AT THE DEALER STATED THAT THIS IS A COMMON PROBLEM WITH THIS MODEL. THIS HAS HAPPENED AT LEAST 10 TIMES.

NHTSA ODI 11282725

CAR CONTINUES TO TELL YOU TO SHIFT TO PARK AFTER IT HAS BEEN PLACED IN PARK. THE CAR WILL NOT ALLOW YOU TO LOCK OR EXIT THE VEHICLE. TO REMEDY YOU MUST SHAKE THE GEAR SHIFT, OR WAIT A PERIOD OF TIME, START THE CAR, PLACE IN DRIVE AND SHIFT BACK TO START. SOMETIMES, YOU HAVE TO DO THIS SEVERAL TIMES BEFORE THE CAR WILL REALIZE IT IS IN PARK.

NHTSA ODI 11282422

WHEN I SHIFT THE CAR TO PARK AND TURN IT OFF, I GET A WARNING ON THE DASH THAT INSTRUCTS ME TO "SHIFT TO PARK" EVEN THOUGH I ALREADY HAVE. THE VEHICLE WILL NOT TURN OFF, AND AS A RESULT I HAVE TO TURN THE CAR ON AND OFF SHIFTING REPEATEDLY UP TO 20 TIMES TO FINALLY GET THE CAR TO RECOGNIZE IT'S IN PARK. THE VEHICLE IS TOTALLY UNSAFE AS IT WILL NOT STAY IN PARK!
