2018 GMC ACADIA Power Train Problems

WHEN THE VEHICLE IS SHIFTED INTO PARK AND THE IGNITION IS TURNED OFF, AN ERROR MESSAGE IS SHOWN SAYING "SHIFT VEHICLE INTO PARK". USUALLY PUSHING THE SHIFT KNOB FORWARD AND RELEASING IT WILL MAKE THE ERROR MESSAGE DISAPPEAR BUT THERE HAVE BEEN TIMES THAT THE VEHICLE HAD TO BE TURNED ON AND OFF MULTIPLE TIMES AS WELL AS SHIFTING FROM DRIVE TO PARK MULTIPLE TIMES TO MAKE IT GO AWAY AND TURN THE VEHICLE OFF.

THE VEHICLE SOMETIMES FAILS TO RECOGNIZE THAT IT HAS BEEN PUT INTO PARK, FLASHING A MESSAGE ON THE DASH INSTRUCTING ME TO 'SHIFT TO PARK' EVEN WHEN THE GEAR LEVER HAVE ALREADY BEEN MOVED TO THE 'P' POSITION.

I SHIFTED THE GEAR INTO PARK, AND A MESSAGE APPEARED SAYING TO "SHIFT TO PARK" AND WOULDN'T ALLOW THE CAR TO BE TURNED OFF OR ITS DOORS LOCKED. THIS IS A SAFETY ISSUE BECAUSE THE CAR IS UNABLE TO SHIFT INTO PARK AND COULD ROLL BACK.

2018 GMC ACADIA. THE CROSSOVER (AUTOMATIC GEAR SHIFTER) IS FAILING TO RECOGNIZE THAT IT HAS BEEN PUT INTO PARK, FLASHING A MESSAGE ON THE DASH INSTRUCTING THE DRIVER TO 'SHIFT TO PARK' EVEN WHEN THE GEAR LEVER HAVE ALREADY BEEN MOVED TO THE 'P' POSITION.

RECEVIED "ACTION REQUIRED - SHIFT TO PARK" MESSAGE ON INSTRUMENT PANEL SCREEN. MOTOR TURNS OFF BUT VEHICLE STAYS IN ACCESSORY MODE AND CHIMES CONTINUOUSLY. DEALER REPLACED WIRING HARNESS THAT PROMISED TO FIX THE PROBLEM, WENT AWAY FOR 1 MONTH AND CAME BACK. JIGGLING THE SHIFTER OR FLICKING THE SHIFTER BUTTON IS THE ONLY WAY IT WILL GO AWAY.

EXPERIENCED THE "VEHICLE NOT IN PARK " WHEN SHIFTER WAS IN PARK. ENGINE WOULD NOT TURN OFF BECAUSE ELECTRICAL SWITCH DID NOT RECOGNIZE THE VEHICLE WAS IN PARK. AFTER MANY TRIES I WAS ABLE TO TURN VEHICLE OFF. HAD VEHICLE SERVICED AND SHIFTER WAS REPLACED (3 WEEKS AGO ). TODAY SHIFTER FROZE IN PARK YET CONSOLE INDICATED VEHICLE WAS IN DRIVE. DID NOT REMOVE FOOT OFF OF BRAKE BECAUSE VEHICLE WOULD MOVE FORWARD BECAUSE IT WAS IN GEAR. COULD NOT SHUT OFF VEHICLE BECAUSE IT IS A PUSH BUTTON START/STOP AND FOOT MUST BE OFF BRAKE TO STOP ENGINE. CALLED DEALER FOR HELP. FINALLY WE PUT EMERGENCY BRAKE ON AND PUSHED STOP BUTTON. THE ENGINE TURNED OFF BUT ELECTRICAL SYSTEM WAS STILL ON. HAD VEHICLE TOWED TO DEALER. THEY WILL ADVISE IN A WEEK OR SO THEY ARE SHORT HANDED.

VEHICLE STATES "ACTION REQUIRED - SHIFT TO PARK" EVEN THOUGH VEHICLE IS IN PARK. ACCESSORIES STAY ON AND VEHICLE CONTINUOUSLY SOUNDS WARNING CHIME. THIS PROBLEM OCCURS EVERY TIME THE VEHICLE IS SHIFTED TO PARK AND ENGINE IS SHUT DOWN.

VEHICLE WILL NOT SHUT OFF DUE TO A SHIFT TO PARK MESSAGE WHEN THE SHIFTER IS ALREADY IN THE PARK POSITION.

'ACTION REQUIRED SHIFT TO PARK' - MESSAGE. STATIONARY. THE CAR IS IN PARK! BELLS SOUND. DOORS LOCK. BATTERY DRAINS. HUNDREDS OF OTHER FOLKS HAVE REPORTED THE SAME ISSUE ONLINE. PLEASE RECALL THIS CAR, DANGEROUS AND I HAVE KIDS.

THE VEHICLE WILL NOT ALWAYS GO INTO PARK. IN ORDER TO GET IT INTO PARK YOU HAVE TO REPEATEDLY SHIFT OUT OF PARK AND BACK INTO PARK UNTIL IT WILL GO INTO PARK. IF IT IS NOT IN PARK THE VEHICLE WILL NOT LOCK AND WILL NOT POWER DOWN. SINCE IT WILL NOT GO INTO PARK IF THE VEHICLE WAS ON A HILL AND IT DID NOT GO INTO PARK THEN IT WOULD HAVE THE CHANCE TO ROLL DOWN THE HILL. I HAVE NOT ATTEMPTED TO SEE IF IT WILL ROLL DOWN THE HILL NOR AM I GOING TO TRY BUT SEEING HOW IT SHOWS ON THE INSTRUMENT CLUSTER THAT THE VEHICLE IS IN NEUTRAL I'M SURE IT WILL ROLL IF GIVEN THE CHANCE. WHEN SHUTTING OFF THE VEHICLE AFTER YOU HAVE PUT THE VEHICLE IN PARK ON THE GEAR SELECTOR A MESSAGE COMES UP ON THE SCREEN THAT SAYS...

TOOK OUR ACADIA IN ON 9/25 AFTER SEVERAL WEEKS (STARTED THE WEEK OF 8/26) OF THE SHIFT TO PARK INDICATOR LIGHT KEPT COMING ON. THE DEALERSHIP HAD IT FOR SEVERAL WEEKS (P/U 10/16) BECAUSE THEY COULDN'T GET THE PARTS DUE TO THE GM STRIKE. WE HAVE HAD IT BACK THREE WEEKS AND IT HAS BEGUN AGAIN WITH THE SHIFT TO PARK LIGHT. WE KEEP THE PARKING BREAK ON JUST IN CASE, DON'T TRUST IT. HAVE ANOTHER SERVICE APPOINTMENT ON 11/15. WE WILL SEE WHAT HAPPENS.

WHEN PUTTING VEHICLE IN PARK, MESSAGE COMES UP ON DASHBOARD "SHIFT TO PARK." SOMETIMES TAKES MULTIPLE ATTEMPTS TO GET VEHICLE INTO PARK SO VEHICLE CAN BE TURNED OFF. HAVE TO SHIFT BETWEEN DRIVE, REVERSE AND PARK OR WIGGLE SHIFTER AND PUMP BRAKE TO GET MESSAGE TO GO AWAY.

WARNING MESSAGE SAYS "SHIFT TO PARK". MESSAGE DOES NOT GO OFF UNTIL YOU TURN CAR ON AND OFF SEVERAL TIMES; PUTTING THE CAR IN REVERSE, THEN DRIVE; THEN SHIFTING BETWEEN GEARS BACK AND FORTH. MAY TAKE 20 MINUTES TO GET THE MESSAGE LIGHT TO GO OFF. GMC HAS TRIED REPLACING GEAR SHIFT, PART OF GEAR TOP. AFTER 5 ATTEMPTS IN TRYING TO FIX THE ISSUE, MY CAR SITS AT THE DEALERSHIP FOR AN ADDITONAL 4 WEEKS WAITING FOR A HARNESS FIX (WHICH THERE IS NO PART FOR). THE CAR ALWAYS ROLLS BACKWARDS WHEN THE MESSAGE FINALLY GOES OFF. THIS IS A MAJOR SAFETY ISSUE. IS THE CAR REALLY IN PARK?

1 OUT OF 2 TIMES A DAY WHEN I PUT THE VEHICLE IN PARK IT GIVES ME A WARNING TO SHIFT TO PARK ON THE ELECTRONIC DASH. EVEN THOUGH THE SHIFT IS SITTING IN THE PARK POSITION. SO I HAVE TO RESTART THE CAR, TAKE IT OUT OF PARK AND SHIFT BACK TO PARK MULTIPLE TIMES BEFORE THE WARNING GOES AWAY. THIS WARNING PREVENTS THE CAR FROM COMPLETELY SHUTTING DOWN

VEHICLE ENGINE WAS RUNNING WHEN I CAME TO A STOP AND SHIFTED TO PARK. I RECEIVED AN ERROR INDICATING "ACTION REQUIRED - SHIFT TO PARK." I DID NOT LET OFF OF THE BRAKE PEDAL BECAUSE I WAS UNSURE IF THE VEHICLE HAD ACTUALLY SHIFTED INTO PARK. WITH THE BRAKE PEDAL APPLIED, I ATTEMPTED TO SHIFT TO NEUTRAL AND DRIVE, THEN SHIFT BACK TO PARK, AND RECEIVED THE SAME ERROR. WITH MY FOOT STILL ON THE BRAKE, I TURNED THE IGNITION OFF, BUT THE ELECTRONICS WOULD NOT POWER OFF AND THE ERROR CONTINUOUSLY DISPLAYED ON THE DASH. I STARTED THE ENGINE AND REPEATED THIS PROCESS MULTIPLE TIMES WITH THE BRAKE PRESSED BEFORE CHANGING GEARS AGAIN, SHIFTING INTO PARK, THEN APPLYING THE ELECTRONIC PARKING BRAKE WITH THE ENGINE RUNNING. IT WAS ONLY THEN THAT I TURNED MY ENGINE OFF AGAIN, AND THE ERROR FINALLY NO LONGER DISPLAYED. SINCE THE ERROR WAS NO...

AFTER SHIFTING MY ACADIA INTO PARK AND SHUTTING IT OFF, "SHIFT TO PARK" WARNING COMES US SOUNDING AN ALARM THAT WON'T GO OFF UNLESS I START THE CAR AND SHIFT IN AND OUT OF PARK SEVERAL TIMES. IT GETS HARDER TO GET THE WARNING TO GO AWAY EACH TIME I DRIVE IT. I HAVE HAD TO RESULT TO NOT DRIVING IT TO AVOID THE BATTERY DRAINING OR HAVING TO UNHOOK THE BATTERY. THE CAR ONLY HAS 19000 MILES SO THE DEALER IS WILLING TO REPLACE IT BUT THERE ARE NO PARTS AVAILABLE. ALSO, OTHERS HAVE MENTIONED THAT THE PROBLEM RETURNS EVEN AFTER THE REPAIR.

WE HAVE AN ISSUE WITH THE GEAR SHIFT, SINCE THREE WEEKS AGO WE CAN'T TURN OFF THE ENGINE AS A NORMAL PROCEDURE BECAUSE THE SENSOR OF THE GEAR SHIFT DOESN'T DETECT THE SHIFT IS IN 'P' PARKING, WE CONTINUALLY RECEIVE A MESSAGE FROM THE SCREEN. 'PUT YOUR SHIFT IN 'P', BUT IN THIS PRECISE MOMENT THE SHIFT WAS IN PARKING MODE, SO WE CAN'T TURN OF THE ENGINE. WE RECEIVE A NOTIFICATION FROM THE MECHANICAL WORKSHOP THAT THE ISSUE COULD BE THE ELECTRICAL HARNESS, BUT THEY DOESN'T GIVE US WHEN COULD BE CHANGED, SO RIGHT NOW WE HAVE MORE THAN TWO WEEKS WITHOUT USE THE VEHICLE, THEY DO NOT RECEIVE A OFFICIAL FEEDBACK FOR THE PLANT YET.

SHIFT TO PARK NOTICE. WHEN ATTEMPTING TO TURN OFF VEHICLE AND SHIFTED INTO PARK, VEHICLE WILL GIVE A WARNING THAT VEHICLE IS NOT IN PARK. AT THIS POINT I HAVE NO IDEA IF THE VEHICLE IS IN PARK OR NOT. NOT SURE IF I AM JUST RECEIVING A FAULTY NOTICE OR IS THE VEHICLE NOT IN PARK AND COULD ROLL CAUSING INJURY! THIS IS NOT A SAFE VEHICLE. GMC UNABLE TO REPAIR DUE TO NOT HAVING THE PART AVAILABLE. THIS MAY HAPPEN FOR TWO OR THREE TIMES. IT HAS HAPPENED THAT I HAVE HAD TO TURN MY CAR OFF AND BACK ON UP TO SEVEN TIMES BEFORE IT REGISTERED AS IN PARK.

THE SHIFTER IS IN PARK WITH THE P LIT UP, BUT I CANNOT SHUT OFF MY CAR. A MESSAGE COMES ON THE SCREEN THAT SAYS SHIFT TO PARK THEN PUSH OFF. IT CONTINUES TO RUN UNTIL I TAKE IT OUT OF PARK AND PUT IT BACK IN.

WHEN TURNING OFF THE VEHICLE, A WARNING MESSAGE COMES ON SAYING "SHIFT TO PARK" EVEN THOUGH THE VEHICLE IS IN PARK. THE SHIFTER READS PARK AND SO DOES THE DASH. VEHICLE IS UNABLE TO BE COMPLETELY TURNED OFF OR LOCKED WITH THIS MESSAGE APPEARING. IT REQUIRES TURNING VEHICLE ON AND OFF, MOVING SHIFTER IN AND OUT OF PARK, JIGGLING SHIFTER BUTTONS, ETC. THIS CAN TAKE ONE TRY OR MULTIPLE TRIES. I JUST HAD THIS FIXED BY THE DEALERSHIP (REPLACED SHIFT CONTROL) AND WAS DISAPPOINTED TO FIND THAT THIS IS A KNOWN ISSUE, AFFECTING MANY VEHICLES AND IT IS STILL THE RESPONSIBILITY OF THE VEHICLE OWNER TO PAY FOR THE EXPENSE IF THE BUMPER TO BUMPER WARRANTY IS EXPIRED. THE SHIFTER RUNS THE POWER TRAIN! WHY IS THIS NOT UNDER THE POWER TRAIN WARRANTY AND WHY IS THIS NOT A RECALL? NOW, IN RESEARCHING, I'M SEEING THAT MANY HAVE HAD IT...

WHEN SHUTTING THE ACADIA OFF IT PROMPTS A MESSAGE SAYING MUST BE IN PARK. IT IS IN PARK BUT COMPUTER IS NOT RECOGNIZING IT. THIS FORCES YOU TO LEAVE CAR RUNNING. IF YOU DONT THEN YOUR BATTERY WILL GO DEAD. WHEN SPEAKING TO LOCAL DEALERSHIP THEY ARE AWARE OF ISSUE BUT DONT KNOW ANYTHING TO RESOLVE IT. CUSTOMERS SHOULDN'T HAVE TO PAY FOR THIS SINCE IT'S A SAFETY ISSUE.

CAR WARNS TO PUT IN PARK WHEN IT IS IN PARK. DEALER FIXED IT A YEAR AGO AND IT HAS STARTED AGAIN

WHEN PUTTING MY VEHICLE IN PARK AND PRESSING THE ENGINE OFF BUTTON, I GET AN ERROR MESSAGE "SHIFT TO PARK", AND THE VEHICLE BEEPS AND WILL NOT TURN OFF THE ELECTRICAL, BUT THE CAR IS ALREADY IN PARK. I AM UNABLE TO TURN OFF MY VEHICLE COMPLETELY. I HAVE TO PRESS START AGAIN AND PUT THE CAR IN REVERSE AND BACK TO PARK, SOMETIMES MULTIPLE TIMES IN ORDER FOR THE VEHICLE TO REGISTER THAT IS IN PARK AND ALLOW ME TO SHUT OFF MY VEHICLE COMPLETELY. I AM CONCERNED THAT THE VEHICLE MAY NOT ACTUALLY BE IN PARK WHEN I PUT IT IN PARK. I DO NOT WANT IT TO ROLL DOWN A HILL AND I WANT TO BE ABLE TO TURN OFF MY CAR WITHOUT BEING CONCERNED IT WILL CONTINUE TO RUN ELECTRICAL AND KILL MY BATTERY.

VEHICLE STATES "ACTION REQUIRED - SHIFT TO PARK" EVEN THOUGH VEHICLE IS IN PARK. ACCESSORIES STAY ON AND VEHICLE CONTINUOUSLY SOUNDS WARNING CHIME. THIS PROBLEM OCCURS EVERY TIME VEHICLE IS SHIFTED TO PARK.

WHEN THE CAR IS SHIFTED INTO PARK, THE DASHBOARD SHOWS A WARNING THAT THE CAR IS NOT IN PARK. THE CAR THEN WON'T TURN OFF COMPLETELY.

THE VEHICLE SHOWS A WARNING WITH A BELL TONE 'SHIFT TO PARK' WHEN THE CAR IS ALREADY IN PARK. IT STOPS ONLY AFTER WIGGLING GEAR SHIFTER NUMEROUS TIMES.

SHIFT TO PARK I SHIFT THE CAR INTO PARK AND TRY AND TURN THE CAR OFF AND IT STILL SAYS SHIFT TO PARK LIKE THE CAR ISNT IN PARK BUT IT IS. IT WONT ALLOW ME TO TURN THE CAR OFF. I HAVE TO SHIFT IT INTO DIFFERENT GEARS OR JIGGLE THE SHIFTER FOR IT TO REGISTER. I HAVE HAD TO RESORT TO REMOVING THE BATTERY CABLES OFF TO TURN IT OFF ONE TIME AS WELL. THE CAR WHEN IT DOES SHUT OFF FEELS LIKE THE TRANSMISSION ISNT FULLY ENGAGED.

FIRST OF ALL, THIS ISSUE IS BEING REPORTED BY HUNDREDS IF NOT THOUSANDS OF GMC ACADIA OWNERS. I RECEIVED THE "SHIFT TO PARK" MESSAGE MONTHS AGO WHILE IT STILL WAS UNDER THE 36,000 MILE WARRANTY AND THEN IT WENT AWAY UNTIL LAST WEEK. I GOT A "SHIFT TO PARK" MESSAGE WHEN I TURNED THE VEHICLE OFF EVEN THOUGH THE GEAR WAS IN THE SHIFT POSITION. THIS CAUSED A NUMBER OF SECONDARY ISSUES THAT ARE NOW COMPROMISING THE SAFETY OF THE VEHICLE. ONCE I AM ABLE TO TURN THE VEHICLE BACK ON AFTER IT DRAINS OR KILLS THE ELECTRICAL SYSTEM, I AM GETTING A NUMBER OF ISSUES. HOWEVER, THE ONES THAT CONCERN ME THE MOST ARE THE ROLLS EVEN THOUGH THE VEHICLE IS IN PARK, LOSS OF POWER STEERING, LOSS OF AWD, LOSS OF STABILITRACK, LOSS OF ABS, BRAKING SYSTEM ERROR AND POWER SURGES. THESE ARE THE MOST CONCERNING BUT I...

MY 2018 GMC ACADIA HAS WARNING OF SHIFT TO PARK. WHEN IT IS IN PARK. AND WILL NOT ALLOW ME TO TURN OFF THE CAR. I FEEL THIS IS A MAJOR ISSUE. THIS ONLY HAPPENS WHEN IT IS STATIONARY.

2018 GMC ACADIA VIN [XXX] MY CAR HAS 41,000 MILES. WHEN I PARK AND TRY TO SHUT MY CAR OFF A MESSAGE POPS UP THAT SAYS "SHIFT TO PARK". IT WILL NOT ALLOW ME TO SHUT MY CAR OFF BECAUSE IT DOES NOT IDENTIFY THAT IT IS IN FACT IN PARK. TODAY IT TOOK ME 15 MINUTES OF TURNING MY CAR OFF AND ON AND SHIFTING IN AND OUT OF PARK TO GET IT OFF. TWO DAYS AGO MY CAR STARTED TO ROLL BACKWARDS AS IF IT WERE IN NEUTRAL. THIS IS A SERIOUS SAFETY HAZARD AND NEEDS TO BE RECALLED! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

GMC ACADIA WILL NOT REGISTER WHEN THE DRIVER SHIFTS THE GEARS INTO PARK. AN ERROR MESSAGE 'SHIFT TO PARK' IS SHOWN ON THE DASHBOARD EVEN THOUGH THE GEAR IS IN PARK. THE DRIVER IS UNABLE TO TURN THE CAR OFF BECAUSE OF THE ERROR MESSAGE. IT TAKES SEVERAL TURNS OF SWITCHING THE CAR ON AND OFF AND FLIPPING THROUGH ALL THE GEARS IN ORDER FOR THE MESSAGE TO DISAPPEAR SO THAT THE CAR TURNS OFF. THE CAR WAS TAKEN TO THE DEALER ON JUNE 26 FOR REPAIRS AND HAS BEEN SITTING THERE OVER A MONTH BECAUSE THEY ARE UNABLE TO CORRECT THE ISSUE.

TL* THE CONTACT OWNS A 2018 GMC ACADIA. WHEN THE VEHICLE WAS TURNED OFF, THE INSTRUMENT PANEL REMAINED ILLUMINATED AND "PUT THE VEHICLE IN PARK" WAS DISPLAYED. AS A RESULT, THE BATTERY DIED. THE CONTACT CALLED RENO BUICK GMC CADILLAC AT 775-333-0000 (LOCATED AT 900 KIETZKE LN, RENO, NV 89502) AND SCHEDULED A DIAGNOSTIC APPOINTMENT. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND STATED THAT THERE WAS NO RECALL. THE CONTACT WAS REFERRED TO THE DEALER. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 37,000.

WHILE STATIONARY, INSTRUMENTS SHOW A SHIFT TO PARK MESSAGE, EVEN THOUGH THE CAR WAS IN PARK. ACADIA WOULD NOT FULLY TURN OFF UNTIL THIS MESSAGE IS NOT PRESENT. THE ONLY WAY FOUND TO HAVE THE MESSAGE CLEAR IS TO CONTINUALLY SHIFT FROM DRIVE TO PARK UNTIL IT RECOGNIZES THAT THE CAR IS INDEED IN PARK. THIS HAPPENS REPEATEDLY - 8 OUT OF 10 TIMES I DRIVE MY CAR.

CANNOT LEAVE CAR. "SHIFT TO PARK" MESSAGE APPEARS EVEN WITH CAR IS PARKED. SOMETIMES TAKES 15 MINUTES TO PUT CAR IN PARK

WHEN I TRY TO SHUT OFF IGNITION I GET A WARNING ON THE DASH THAT SAYS TO PUT VEHICLE INTO PARK BEFORE SHUTTING THE VEHICLE OFF EVEN THOUGH THE VEHICLE IS IN PARK ALREADY. I HAVE TO SHIFT IN AND OUT OF PARK OR RIDE AROUND AGAIN AND THEN TRYING PARKING AGAIN TO GET IT TO SHUT OFF. ONCE I EVEN LEFT IT RUNNING AND WENT INTO THE STORE BECAUSE I COULD NOT GET THE VEHICLE TO SHUT OFF DUE TO IT THINKING IT WAS NOT IN PARK AND IT WAS.

AFTER PARKING, MY ACADIA WOULD NOT SHUT OFF COMPLETELY. A MESSAGE CAME ON THE DASH, 'ACTION REQUIRED, SHIFT TO PARK'. A CONSTANT CHIME WAS SOUNDING ALSO. I RESTARTED THE CAR, SHIFTED OUT OF PARK, BACK INTO PARK, TRIED TO SHUT OFF AGAIN...SAME THING....4X'S!!! I WENT RIGHT OVER TO THE DEALER WHERE I BOUGHT MY CAR AND EXPLAINED WHAT WAS HAPPENING ( COULDN'T SHUT OFF THERE EITHER). SERVICE MANAGER KNEW IMMEDIATELY WHAT THE PROBLEM WAS BUT SAYS THE PART (GEAR SHIFT) IS ON BACKORDER AND HAS NO IDEA FOR HOW LONG!!! WHAT??? WHY ISN'T THIS A RECALL? I'VE READ QUITE A FEW OF THIS SAME COMPLAINT SO I CAN'T UNDERSTAND HOW THIS ISN'T A RECALL ALREADY ESPECIALLY IF THE GEAR SHIFT REQUIRED TO FIX THE PROBLEM IS ON BACKORDER, IT'S OBVIOUSLY A BIGGER ISSUE THEN 1 OR 2. SO FOR NOW , I JUST HAVE TO WAIT AND 'KEEP PLAYING WITH...

1* PURCHASED MARCH 2018 (ACADIA DENALI) SINCE AUGUST 2018 IN MOTION WHEN I ACCELERATE IT SOUNDS LIKE A LOUD LAWNMOWER & CRACKLING SOUND IN REAR MUFFLER AREA. TOOK IT CHEVY PLACE IN GLENPOOL, OK. THEY COULDN'T FIND ANYTHING. 2* ON 2 OCCASSIONS, IN MOTION, THE CAR ACCELERATED WITH A LOUD NOISE & AS IF IT WERE GETTING POWER & NOT MOVING THEN JERKS & SPEEDS UP ABOUT 15MPH FASTER & I COULDN'T STOP IT. I KEPT SLAMMING ON MY BREAKS, BUT THE BREAK WOULD ONLY GO IN SO FAR. I WAS FRIGHTENED WITH MY 2 YOUNG BOYS IN CAR SCREAMING. IT'S LIKE RIDING A HORSE & IT TAKES OFF & YOU CAN'T CONTROL IT. 3* ON ABOUT 8 OR 9 OCCASSIONS STATIONARY I GET OUT OF MY CAR & IT MAKES A REALLY LOUD ANNOYING SOUND LIKE A MACHINE/ROBOT POWERING DOWN. MY KIDS ALWAYS SAY, IT'S GOING TO BLOW UP...

WHEN I GO TO PUT CAR IN PARK AND GO TO TURN IT OFF IT SAW SHIFT TO PARK ON THE INFORMATION SCREEN. THE SHIFTER IS IN PARK AND P FLASHES ON AND OFF ON THE SHIFTER. GMC HAS SAID THEY DO NOT HAVE A FIX FOR THIS. THIS IS A SAFETY ISSUE IF YOU THINK YOU'RE IN PARK AND GO TO GET OUT AND IT IS NOT.

I FINANCED THIS VEHICLE IN MAY 2018 THROUGH A GMC DEALERSHIP. IT IS JANUARY 2019 I STARTED GETTING ALERTS ONCE I PUT MY CAR IN PARK AND TURNED THE MOTOR OFF. THE WARNING ALERTS STATED ON THE DASHBOARD "ACTION REQUIRED -SHIFT TO PARK-" EVEN THOUGH IT IS IS PARK. THE ALERT IS LOUD AND WILL NOT GO OFF. I HAVE TO START THE CAR AGAIN AND ADJUST THE GEAR SHIFT A FEW TIMES BY MOVING IT TO DRIVE, NEUTRAL OR REVERSE BEFORE THE VEHICLE RECOGNIZES THAT IT IS IS PARK AND THE ALERT LEAVES THE SCREEN AND THE SOUND GOES OFF. SOMETIMES IT TAKES A FEW MOMENTS OF MOVING THE GEAR SHIFT BEFORE I AM ABLE TO LEAVE THE VEHICLE. THIS IS HIGHLY INCONVENIENT ESPECIALLY WHEN YOU ARE IN A HURRY TO LEAVE THE VEHICLE. I AM EXTREMELY FRUSTRATED BECAUSE THIS IS A BRAND NEW VEHICLE. I CONTACTED THE DEALER...

WHEN I PUT THE IN PARK, IT DOES NOT RECOGNIZE THAT THE VEHICLE IS ALREADY ENGAGED. THE CONSOLE DISPLAYS TELLS ME TO PUT VEHICLE IN PARK AND BEEPS. I HAVE TO KEEP MOVING THE GEAR SHIFT FROM REVERSE TO NEUTRAL TO PARK SEVERAL TIMES BEFORE IT RECOGNIZES THE VEHICLE IN ENGAGED IN PARK. THIS HAS BEEN HAPPENING ABOUT 8 MONTHS OR SO. I HAVE MENTIONED IT TO THE DEALER AND THEY TELL ME THEIR ARE NO RECALLS FOR MY PROBLEM, NOT EVEN RECOGNIZING MY PROBLEM WITH THE VEHICLE.

WHEN YOU PUT THE SHIFTER IN PARK IT DOES NOT RECOGNIZE & CABIN ALARM STARTS TO BEEP. THE VEHICLE WILL ALSO LEAVE ITS HEADLIGHTS ON OVERNIGHT & DRAIN YOUR BATTERY. TOOK TO DEALER AND THEY COULDN'T DO ANYTHING ABOUT IT. IT'S BEEN 2 WEEKS AND NO LETTER OF RESOLUTION FROM MANUFACTURER AS THE DEALER SAID.
