GMC Complaints

I PURCHASED MY 2019 TERRAIN DENALI ON 2/27/19. I BEGAN MY DRIVE INTO WORK THIS MORNING (3/4/19) AND MERGED ONTO THE FREEWAY AND SECONDS LATER HEARD A LOUD EXPLOSIVE SOUND, ONLY TO REALIZE THE FIRST HALF OF MY PANORAMIC MOONROOF WAS SHATTERED (SEE INSIDE PHOTO). SHARDS OF GLASS WERE FALLING INTO THE VEHICLE BUT IT HAD NOT COLLAPSED COMPLETELY AT THIS POINT. I DID NOT DRIVE UNDER ANYTHING THAT MAY HAVE FALLEN, THERE WERE NO OBJECTS IN THE ROAD THAT CAME UP TO HIT MY VEHICLE, THE GLASS JUST SHATTERED OUT OF NOWHERE. AFTER CALLS WITH THE DEALERSHIP AND ROADSIDE ASSISTANCE, I DECIDED TO ATTEMPT TO CLOSE THE INSIDE COVER FOR THE MOONROOF AND DRIVE TO THE DEALERSHIP. I WAS ABLE TO DO SO SUCCESSFULLY BUT AS SOON AS I MOVED THE VEHICLE, YOU COULD HEAR THE GLASS COLLAPSE (SEE PICTURE).

MY 2008 GMC ACADIA HAS HAD A RECURRING ISSUE WITH THE PASSENGER AIRBAG SENSOR. A NOTIFICATION IN THE DASHBOARD SAYS "SERVICE AIR BAG". I TOOK IT TO THE GMC DEALERSHIP WHERE I PURCHASED IT IN RICHMOND VA SOON AFTER PURCHASING. THEY SAID THEY COULD NOT RECREATE THE PROBLEM. IT CONTINUED TO BE A PROBLEM. THE GMC DEALERSHIP IN MANASSAS VA SAID THEY FIXED IT WHEN I TOOK IT TO THEM LATER. I TOOK IT BACK A MONTH LATER BECAUSE THEIR "FIX" DID NOT WORK AND THE "SERVICE AIR BAG" INDICATOR STILL COMES ON. BEFORE IT WOULD COME ON PERIODICALLY, BUT NOW IT IS ON ALMOST ALL THE TIME. MY CAR DOES NOT PASS INSPECTION NOW AND THE GMC DEALERSHIP WANTS $1000 TO REPLACE THE SENSOR EVEN THOUGH THIS HAS BEEN A PROBLEM WITH THE CAR SINCE I PURCHASED IT FROM THE DEALER.

STARTED MARCH OF 2017 PROGRESSIVELY GETTING WORSE. SUV JERKS, GAUGES GO CRAZY, CHECK ENGINE LIGHT COMES ON, IF SLOW TO BELOW 20 MPH IT SPUTTERS AND WON'T ACCELERATE, IF I STOP COMPLETELY IT WON'T ACCELERATE. MULTIPLE TIMES THIS HAS HAPPENED ON THE INTERSTATE DURING RUSH HOUR TRAFFIC & AT BUSY INTERSECTIONS. IF I TURN CAR OFF AND BACK ON THE SYSTEM RESETS. THEN IT STARTS ALL OVER AGAIN. IT HAS BEEN IN AND OUT OF THE SHOP. PROBABLY 10-15 TIMES IN 2YEARS. THEY GET CODES, BUT THEN THESE GO AWAY BEFORE THEY CAN BE 'RUN'. I BROKE DOWN 1-1/2 WEEKS AGO IN BAY MINETTE & THE CAR WOULDNT START BACK UP. I WAS STRANDED OUT OF TOWN AND HAD TO RENT A CAR TO GET BACK HOME. THE DEALER THERE GOT 7 ERROR CODES THAT ALL CLEARED OUT. I HAVE FILED A COMPJAINT WITH GMC, BUT THEY ARE SLOW TO HANDLE THE PROBLEM & I CAN'T GET SUPERVISORS ON THE PHONE OR AT LEAST ONE WHO DOESN'T SEEM LIKE HE'S BEEN DRINKING.

ENGINE SHUTS OFF, STEERING ASSIST DISAPPEARS AND STEERING WHEEL IS JERKED OUT OF MY HAND, STABILITRAK WARNINGS ON DASH, HVAC SCREEN GOES BLANK, CHIMES START GOING OFF. THIS OCCURRED AS I WAS PULLING INTO A PARKING LOT AND I ALMOST HIT ANOTHER CAR. THE VEHICLE WAS MOVING AT NO MORE THAN 10MPH.

COULD NOT GET THE RECALL REPAIRED AS THE COMPANY THAT MAKES THE AIR BAG IS NO LONGER IN BUSINESS. TAKATA. A FAILURE OF THE FRONT AIR BAGS OR SEAT BELT PRETENSIONERS TO DEPLOY IN THE EVENT OF A CRASH NECESSITATING DEPLOYMENT

PURCHASED A USED 2017 GMC YUKON DENALI WITH ALMOST 36,000 MILES. 4 DAYS AFTER THE PURCHASE MY ENGINE LIGHT CAME ON. NEXT MORNING THE VEHICLE WAS NOT DRIVING RIGHT, VERY SLOW MOVING (COULDN'T GO FASTER THAN 45 MILES PER HOUR), VERY SHAKY, LOUD, FELT LIKE IT WAS EITHER GOING TO DIE ON ME OR BLOW UP. HAD ONSTAR CHECK IT OUT WITH SEVERAL ISSUES REPORTED, TOOK TO DEALERSHIP RIGHT AWAY. 3 FUEL INJECTORS WERE FAILING AND WERE REPLACED STILL UNDER WARRANTY. FUEL INJECTOR #3 WAS REPLACED PRIOR TO MY PURCHASE OF THIS VEHICLE AND NOW AGAIN REPLACED ALONG WITH INJECTOR #5 & #8. 2 WEEKS LATER ENGINE LIGHT CAME ON AGAIN. DROVE OK, TOOK TO DEALERSHIP, FUEL INJECTOR #1 NOW GOING OUT. PARTS ON BACK ORDER....GOT A CALL THIS MORNING THAT PARTS ARE IN (HAD TO WAIT OVER A WEEK). I AM NOW OVER THE 36,000 MILES AND WILL THEREFORE BE PAYING TO REPLACE THIS INJECTOR. OPTED TO HAVE ALL THE OTHER INJECTORS REPLACED AS WELL. VERY DISAPPOINTED IN THIS VEHICLE AS IT IS ONLY 2 YEARS OLD. I AM A SINGLE MOM AND NEED A RELIABLE VEHICLE, WHICH THIS VEHICLE IS LESS THAN RELIABLE. HAD THIS VEHICLE A MONTH AND ITS BEEN NOTHING BUT A HEADACHE AND IN THE SHOP 3 TIMES. THESE ISSUES MUST BE COMMON SINCE THE FUEL INJECTORS WERE ON BACKORDER AND THIS PROBLEM SHOULD HAVE A RECALL.

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.

I'VE HAD THIS VEHICLE FOR 3+ YEARS AND RIGHT FROM THE BEGINNING EVERYTIME I CHANGED THE OIL WAS TOLD IT WAS LOW AND ASKED WHERE IT WAS GOING. MY MECHANIC TOLD ME IT WAS A CRANKSHAFT SENSOR CODE AND JUST CHANGE THE OIL AND SO I DID AND THE CHECK ENGINE LIGHT WOULD GO OFF . THEN ONE DAY 800 MILES BEFORE I'M DUE TO CHANGE THE OIL IT STARTS JERKING WHILE STOPPED AND CHECK ENGINE LIGHT CAME ON DISPLAY STATED ENGINE POWER REDUCED THEN IT KEPT STALLING OUT THEN WHEN I SAW AN AUTOZONE STORE THEY CHECKED THE CODE WHICH WAS THE CAMSHAFT SENSOR AGAIN LIMPED HOME AND DID NOTHING LATER WHEN I STARTED THE VEHICLE TO GO TO WORK IT MADE AN AWFUL CLANGING NOISE AND SHUT IT OFF IMMEDIATELY HAD IT TOWED TO THE DEALERSHIP WHERE THEY SAID IT BLEW A REAR SEAL AND WOULD NEED AN 8400 DOLLAR NEW ENGINE THE SPECIAL WARRANTY COVERAGE IS WELL KNOWN BY THE DEALERSHIPS AND TO GM SO WHY WAS THE CONSUMER NOT BEEN NOTIFIED THAT THIS COULD BE A PROBLEM IF I WAS TOLD ABOUT THIS I WOULD NOT HAVE BOUGHT THIS VEHICLE AND I GUESS THAT'S WHAT THEY WANTED A SALE.NOW I HAVE A VEHICLE THAT I STILL HAVE MONTHLY PAYMENTS AND THEY WANT TO CHARGE ME FOR A NEW ENGINE ON TOP OF IT LUDRICAS I SAY

I JUST RECENTLY PURCHASED THIS VEHICLE AND THE SECOND DAY OF HAVING IT ME AND MY HUSBAND WERE DRIVING HOME AN THE POWER STEERING WENT OUT WHILE THE VEHICLE WAS STOPPED TO TURN ONTO ANOTHER ROAD AS WE FINALLY GOT THE STEERING WHEEL TO TURN THE POWER STEERING KICKED IN AN WAS MUCH EASIER TO TURN AGAIN THIS HAPPENED FOR THE REST OF THE DAY AND WAS ONLY HAPPENING WHEN WE WOULD TURN FROM A COMPLETE STOP OR WHEN WE WOULD SLOW DOWN TO STOP. I HAVE HERD THIS WAS IN A GM BULLETIN BUT AM I STILL COVERED UNDER THE BULLETIN WE PURCHASED VEHICLE MARCH 1,2019 AN THE INCIDENT HAPPENED MARCH 2, 2019 WE HAVE OUR CHILDREN WITH US AS WELL AN IF MY HUSBAND HADN'T GRABBED THE WHEEL WITH BOTH HANDS WE WOULD HAVE WENT UNTO ON COMING TRAFFIC. THIS IS NOT SAFE ESPICALLY FOR FAMLIES WITH CHILDREN . PLEASE LET ME KNOW WHAT WILL BE DONE ABOUT THIS UNSAFE DEFAULT.

OEM LED TAIL LIGHTS HAVE FAILED ON MY GMC WITH 40,000 MILES ON IT. THE BULB IS GOOD, YET THE LED PORTION (WHICH COSTS OVER $800 TO FIX) NEEDS TO BE REPLACED. THIS PORTION IS THE ENTIRE REAR BRAKE LIGHT HOUSING. THIS IS VERY COMMON AMONG THESE VEHICLES HEATED SEATS QUIT WORKING ON DENALI. THE BACKRESTS STILL HEAT UP, BUT THE BOTTOMS DON'T HEAT UP AT ALL. ALSO, THEY WILL NOT TURN ON IN REMOTE START MODE EVEN THOUGH THEY ARE SET TO TURN ON IN THIS MODE.
