What 220 owners told NHTSA about the 2016 GMC Acadia Denali

THE TRACTION WARNING SUDDENLY COMES ON THEN THE STABILITY SERVICE WARNING JUMPS ON....AUTOMATICALLY LOWERING MY SPEED WHILE I'M ON THE FREEWAY DRIVING. WHEN I PULL OVER AND TURN THE CAR OFF THEN TURN IT BACK ON...THE LIGHT GOES AWAY. THIS HAPPENED SEVERAL TIMES. DEALERSHIP CAN NOT FIND ANYTHING WRONG. IT HAPPENS WHEN I HIT A POT HOLE OR SPEED BUMP

MY POWERING STEERING PUMP STOPPED FUNCTIONING WHILE DRIVING, MAKING IT VERY HARD TO TURN THE WHEEL AT LOW SPEEDS, AS IF THERE IS NO POWER STEERING AT ALL. TOOK IT TO THE DEALERSHIP AND WAS TOLD IT'S A WEAR AND TEAR PROBLEM AND AFTER INVESTIGATING IT I NOTICED THEY HAVE RECALLED OVER 1 MILLION CARS FOR STEERING FAILURE.

I HAVE A 2016 GMC ACADIA, WITH 30,000 MILES, WELL MAINTAINED. SUDDENLY MY STEERING WHEEL IS LOCKED WHILE MAKING TURNS AT A LOW SPEED. THIS WAS VERY SCARY AS MY WHEEL WAS COMPLETELY LOCKED AND I HAD KIDS IN MY CAR. VEHICLES RUNNING GOOD WHEN AT HIGH SPEED. I HAVE SEEN SO MANY COMPLAIN WITH THE SAME MODEL AND SAME ISSUE, YET, GMC HAS NOT POSTED ANY RECALL ON THEIR VERY DANGEROUS ISSUE.

THE VEHICLE MAKES A CLUNK NOISE THAT COMES FROM THE BRAKES OR ABS. AFTER STARTING THE VEHICLE AND TAKING OFF I HEAR THE CLUNK AND FEEL IT ON THE BRAKE PEDAL. THIS HAPPENS EVERY DAY AND EVERY TIME YOU TAKE OF AFTER STARTING THE CAR. THE GM DEALER TOLD ME THEY KNOW THERE IS AN ISSUE/CONDITION THEY ARE AWARE OF BUT IT'S NOTHING TO WORRY ABOUT. THEY ISSUED A BULLETIN ON THIS CONDITION BUT I DON'T FEEL SAFE DRIVING A CAR THAT MAKES THAT NOISE EVERY TIME AFTER TAKING OFF IN THE ABS SYSTEM. THE CODE THEY GAVE ME IS PI1402A

POWER STEERING PUMP FAILURE. WHILE DRIVING MY 2016 GMC ACADIA ON A TRIP OF ABOUT 350 MILES (MOSTLY HIGHWAY) EVERYTHING SEEMED TO BE WORKING FINE UNTIL NEAR THE END OF THE TRIP. AS I EXITED THE HIGHWAY AND STARTED SLOWING DOWN THE STEERING BECAME VERY STIFF AND BY THE TIME I CAME TO A STOP LIGHT I COULD NOT TURN THE STEERING WHEEL AT ALL. WHEN THE LIGHT TURNED GREEN I PRESSED THE GAS PEDAL AND AS THE RPM INCREASED THE POWER STEERING PUMP WORKED GOOD ENOUGH TO MAKE THE TURN AND GET ME HOME. LUCKILY I ONLY HAD ABOUT A MILE TO GO. I CHECKED THE FLUID AND IT WAS LOW SO I TOPPED IT OFF AND RAISED THE FRONT TIRES OFF THE GROUND IN ORDER TO TURN LOCK TO LOCK TO TRY TO GET ANY AIR OUT OF THE SYSTEM. AFTER LOWERING THE VEHICLE I TRIED TO DRIVE IT AND I STILL COULD NOT TURN THE STEERING WHEEL WITHOUT PRESSING THE GAS. AS I LOOKED FURTHER I NOTICED THAT THE HOSE THAT LEADS TO THE POWER STEERING PUMP HAS FLUID ALL OVER IT WHERE IT GOES THROUGH A GROMMET ATTACHED TO THE REAR OF THE ENGINE. THE GROMMET IN THE METAL BRACKET WAS FALLING APART AND THE HOSE APPEARS TO BE CHAFFING ON THE METAL BRACKET. THE LEAK IS VERY SMALL AND THERE'S NO TELLING HOW LONG IT HAS BEEN RUBBING THE BRACKET. THE VEHICLE IS OUT OF WARRANTY BUT ONLY HAS 50K MILES ON IT AND HAS NEVER BEEN WRECKED OR HAD ANY REPAIRS DONE THAT COULD HAVE CAUSED THIS. IT APPEARS TO BE AN IMPROPERLY INSTALLED BRACKET/GROMMET THAT CAUSED THE PROBLEM.

MY VEHICLE IS A 2016 GMC ACADIA DENALI WITH AWD. THE POWER STEERING WAS VERY STIFF WHILE AT LOW SPEEDS WHEN THE WEATHER WAS COLD LAST WINTER. DURING THIS SPRING AND SUMMER THE STEERING CONTINUED TO GET WORSE AND NOW THERE IS NO POWER STEERING AT LOW SPEEDS AND LOW RPM. THE VEHICLE JUST TURNED 39,000 MILES. THIS MAKES DRIVING VERY DANGEROUS WHILE MAKING TURNS AND TRYING TO PARK THE VEHICLE. THE VEHICLE IS NOW IN THE DEALERS SHOP AND THEY HAVE SAID THE POWER STEERING PUMP AND STEERING GEAR BOTH NEED TO BE REPLACED AS THE PUMP IS FAILING AND THE STEERING GEAR IS LEAKING INTERNALLY.

ON SATURDAY (8/31/2019), I NOTICED THAT THE AC IN MY 2016 ACADIA (ABOUT 79,000 MILES) WOULDN'T TURN ON. MY VEHICLE HAS TWO EVAPORATORS, ONE IN THE FRONT FOR THE FRONT AC, AND ONE IN THE REAR FOR THE REAR AC. THEY ARE CONNECTED BY AN ALUMINUM TUBE (GM PART #23199274). WHEN I TOOK THE VEHICLE INTO THE GMC DEALER, THEY SHOWED ME THAT A CONNECTOR ON THE POWER STEERING FLUID (PSF) LINE, WHICH RUNS BESIDE THIS ALUMINUM TUBE (SEE PHOTO 1), HAD RUBBED UP AGAINST THE ALUMINUM AND WORN A HOLE IN IT, ALLOWING ALL THE REFRIGERANT TO LEAK OUT (PHOTO 2). THERE IS SUPPOSED TO BE A LITTLE RUBBER PIECE THAT FITS OVER AND PROTECTS THE COOLANT LINE (YOU CAN SORT-OF SEE IT IN THE PICTURES), BUT THAT PIECE IS SMALL AND SLIDES DOWN, EXPOSING THE ALUMINUM TUBE. THE TECHNICIAN THEN TOLD/SHOWED ME HOW HE USUALLY BENDS OR MOVES THE PSF LINE SO THAT IT DOESN'T RUB AGAINST THE ALUMINUM COOLANT TUBE. THIS INDICATES THAT GM IS AWARE OF THE ISSUE AND HAS DONE NOTHING IN AN ATTEMPT TO FIX IT, EVEN THOUGH THIS INHERENT DESIGN FLAW ALLOWS THE ENTIRE COOLANT CHARGE TO LEAK INTO THE ATMOSPHERE. NEEDLESS TO SAY, SINCE REFRIGERANT IS NOT EXACTLY ENVIRONMENTALLY FRIENDLY, I FIND IT CONCERNING THAT GM IS APPARENTLY AWARE OF THIS ISSUE AND HASN'T TAKEN THE NECESSARY STEPS (LIKE A VOLUNTARY RECALL) TO FIX IT. I CALLED THE GM CUSTOMER SERVICE LINE AND MADE THEM AWARE OF THE SITUATION, AND THEY SAID "THERE IS NOTHING THEY CAN DO." I'M HOPING THIS COMPLAINT FORCES THEM TO RESOLVE THE ISSUE AND STOP LEAKING FULL REFRIGERANT CHARGES INTO THE ATMOSPHERE. NOTE THAT THIS WOULD ALSO BE AN ISSUE IF THE SITUATION WERE REVERSED AND IT WAS THE AC COOLANT TUBE THAT CHAFED THROUGH THE PSF HOSE. IF THE PSF CONNECTOR WAS EVEN 1 CM OFF, THEN HYPOTHETICALLY THE COOLANT TUBE COULD RUB THROUGH THE PSF HOSE AND CAUSE A FAILURE OF THE POWER STEERING SYSTEM. IT IS ALSO DESIRABLE TO AVOID THIS AS WELL, FOR OBVIOUS REASONS.

THERE HAS BEEN A COUPLE OF INSTANCES WHERE THE CAR JUST SHUTS OFF ONCE WHEN TURNING INTO A PARKING SPACE, AND ONCE WHILE SITTING AT A ROUNDABOUT AND THEN I HAVE TO PUT IT IN PARK AND THEN TURN IT BACK ON. IT SEEMS TO WORK FOR A WHILE AFTER THAT, BUT IT IS EXTREMELY FRUSTRATING FOR A CAR THAT IS NOT THAT OLD AND I JUST GOT IT.

MY KEY IS STUCK IN THE IGNITION AND WILL NOT RELEASE ON MY 2016 GMC ACADIA. THE BATTERY HAD TO BE REPLACED BECAUSE IT WAS COMPLETELY DRAINING MY ELECTRICAL SYSTEM. IT HAS BEEN DETERMINED THAT MY CAR IS NOT RECOGNIZING IT IS IN PARK TO RELEASE THE KEY. THE FLOOR SHIFTER NEEDS TO BE REPLACED ACCORDING TO MY GMC DEALERSHIP. THIS IS EXTREMELY DANGEROUS AS THE CAR COULD DRIFT AT ANY TIME, NOT TO MENTION THE STRAIN ON THE BATTERY.

THE CAR WAS PARKED AND OFF WHEN THE LIFT GATE MALFUNCTIONED. OPENED THE LIFTGATE USING THE BUTTON ON THE GATE, IT OPENED FULLY PAUSED OPEN, THEN SUDDENLY DROPPED 1/3 OF THE WAY CLOSED ON TOP OF MY HUSBAND, IT OPENED AGAIN AND THEN CLOSED QUICKLY ON IT'S OWN. IT REPEATED THE SAME ACTION AGAIN WHEN WE TRIED OPENING. AFTER WE TURNED OFF THE POWER LIFTGATE USING THE BUTTON IN THE DASH WE COULD OPEN THE LIFE HOWEVER WE HAD TO HOLD THE GATE UP, IT WOULD SLAM DOWN IF WE LET GO OF THE GATE. THE LIFE GATE STRUTS WERE FOUND TO BE LEAKING AND REPAIRED. IT IS THE EXACT SAME PROBLEM AS FOUND IN THE RECALLED 2010-2012 ACADIAS
