2019 GMC TERRAIN Complaints

WHEN I SHIFT IT FROM REVERSE TO DRIVE ON A VERY SLIGHT INCLINE, THE ENGINE WILL REV AND NOT ACCELERATE AFTER I INITIALLY START MOVING FORWARD. IT ACTUALLY ALMOST COMES TO A STOP BEFORE FINALLY ACCELERATING. IT HAS NOW STARTED DOING IT WHILE DRIVING AND STALLED IN THE HIGHWAY ON 2/13. I CARRIED IT LAST YEAR FOR THE SAME ISSUE, BUT THEY TOLD ME THEY COULDN'T DUPLICATE IT. TODAY, THEY TOLD ME THE SAME THING. THEY CAN'T EXPLAIN WHY IT STALLED IN THE MIDDLE OF THE ROAD. EVEN THOUGH THE CHECK ENGINE LIGHT CAME ON AND ON-STAR TOLD ME TO CARRY IT TO A DEALER. THE SERVICE TECH GUY ALSO TOLD ME THAT MY VEHICLE HAD 67,000 MILES ON IT. IT HAS LESS THAN 30,000 (NOT SURE ON THE EXACT NUMBER SINCE IT IS STILL AT THE DEALERSHIP.) IT IS NO LONGER SAFE TO DRIVE, BUT SINCE THEY CANNOT DUPLICATE IT, THEY AREN'T EVEN GOING TO INVESTIGATE IT FURTHER.

BOUGHT THE TERRAIN IN NOV 22ND 2020 AT COVINA CHEVROLET, CALIFORNIA. ON NOV 25TH WANTED TO RESTORE THE CAR STEREO BECAUSE THE SETTINGS WOULD NOT DELETE DATA SAVED AND IT WOULDN'T CONNECT TO MY IPHONE VIA USB. SO I DECIDED TO DISCONNECT THE POSTS FROM THE BATTERY TERMINALS FOR 30 MINUTES. CONNECT BACK THE POSTS TO BATTERY AND CHECK IF THAT DELETE EVERYTHING AND IT DID BUT IT STILL WOULDN'T CONNECT TO MY IPHONE. THAT'S WHEN I NOTICED THAT SRS AND SERVICE ESC MESSAGE CAME ON. THE ABS, AIRBAGS AND STABILITY LIGHTS WERE ON, TURN OFF THE VEHICLE AND TURN IT BACK ON AND DIDN'T FIX THE ISSUE. I MADE A REPAIR SCHEDULE WHERE I BOUGHT THE VEHICLE AND TILL THIS DAY DEC 13TH THEY HAVEN'T FIXED THE ISSUE OR THEIR NOT EVEN TRYING. SERVICE ADVISOR ADVISE ME THAT THEY ARE GETTING IN TOUCH WITH A FIELD GM ENGINEER THAT WAS A WEEK AGO. I'M THINKING ITS JUST THE COMPUTER THAT IS FROZEN A MALFUNCTION ABS MODULE CONTROLLER OR A FUSES OR A RELAYS BECAUSE I DROVE THE VEHICLE TO THE DEALER AND HAD NO ISSUE. I LIVE IN OXNARD, CALIFORNIA AND ITS ABOUT 1HR 30MIN FROM THE DEALER. I'M STILL HOPING THAT THEY CAN FIX THE ISSUE BECAUSE I REALLY LIKE THIS VEHICLE. PLEASE HELP GM!!

TL* THE CONTACT OWNS A 2019 GMC TERRAIN. THE CONTACT STATED THAT WHEN THE AIR CONDITION WAS ACTIVATED, THERE WAS AN ABNORMAL CHEMICAL BURNING ODOR COMING THROUGH THE VENTS, CAUSING HE AND HIS WIFE TO GET HEADACHES. THE VEHICLE WAS TAKEN TO MEADOWLAND OF CARMEL GMC (1952 US-6, CARMEL HAMLET, NY 10512) HOWEVER, WAS NOT DIAGNOSED FOR THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE CONTACT STATED THAT WHEN THE VEHICLE WAS FIRST PURCHASED AND THE ODOR WAS FIRST EXPERIENCED, THE DEALER REFUSED TO REPLACED THE VEHICLE WITH ANOTHER VEHICLE. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 24,000. THE VIN WAS NOT AVAILABLE.

9/30/20 DRIVING HOME AND WAS ACCELERATING TO PASS ANOTHER VEHICLE, THE TCS AND STABILITRAK LIGHTS CAME ON AND CHECK ENGINE LIGHT BEGAN TO FLASH. A BRIEF MESSAGE POPPED UP TO SERVICE THE TCS SYSTEM AND WENT AWAY. CHECK ENGINE LIGHT STOPPED FLASHING BUT TCS & STABILITRAK/TRACTION LIGHTS REMAINED ON. I STOPPED THE VEHICLE AS SOON AS I COULD, TURNED IT OFF, WAITING A FEW MINUTES AND RESTARTED - ALL LIGHTS HAD TURNED OFF. PROBLEM HAS NOT REPLICATED, BUT AM SCHEDULED FOR SERVICE (OIL CHANGE) AT DEALER TASCA BUICK GMC SAT OCT 3RD, WILL DISCUSS DURING SERVICE APPOINTMENT. (I COMMUTE DAILY ROUND TRIP 120 MILES) THIS IS EXTREMELY WORRISOME)

ON FEBRUARY 9TH, DRIVING HOME ON A ROUGH HIGHWAY, MY SERVICE ESC, ABS, TRACTION CONTROL AND CHECK ENGINE LIGHT (FLASHING) CAME ON. I IMMEDIATELY PULLED OVER, FREAKING OUT. SHUT MY CAR OFF CAUSE I HAD NO CLUE WHAT TO DO. SAT FOR A FEW MINUTES, COLLECTING MYSELF AND TURNED IT BACK ON. ALL LIGHTS WERE GONE, SO I DECIDED TO CONTINUE THE DRIVE HOME. TOOK MY CAR INTO THE DEALER THE FOLLOWING DAY, FOUND CODE P0300 STORED IN HISTORY. THEY DID AN UPDATE, AND HOPED THAT WOULD SOLVE MY ISSUE. ALAS, IT DID NOT. THIS SAME ISSUE HAS HAPPENED AT LEAST 6 TIMES NOW. THE 5TH TIME, AGAIN, ON A SMOOTH HIGHWAY, I COMPLETELY BROKE DOWN AND HAD TO BE TOWED! IT HAS NOW BEEN SITTING AT THE DEALER FOR TWO WEEKS (SINCE JULY 31ST) WHILE THEY TRY AND DIAGNOSE THE ISSUE.

TWO INCIDENT WARNINGS ON MY DASHBOARD SAYING OF MY BACK HATCH WAS OPEN WHEN IT WAS NOT. HAD IT SERVICED BECAUSE THE DASH WARNING WOULD NOT SHUT OFF. SERVICE SAID IT WAS FIXED THEN HAPPENED AGAIN. TWICE THIS HAPPENED INTERMITTENTLY. ANOTHER INCIDENT WHEN ON NAVIGATION SCREEN, WHEN THE NAVIGATOR GAVE DIRECTIONS IT CHANGED TO PHONE SCREEN AND WENT BACK TO NAVIGATION SCREEN WHEN SHE STOPPED TALKING, LIKE SHE WAS CALLING ME TO VERBALLY GIVE ME DIRECTIONS! THE MOST WORRISOME WAS AS I WAS GOING 50 MPH ON CITY STREET, MY GAS PEDDLE STOPPED ENGAGING WITH THE ENGINE AND I WAS LOOSING SPEED, AS I PRESSED ON THE GAS PEDDLE HARDER THE CAR WAS DECREASING IN SPEED AS I WATCHED THE SPEEDOMETER. DURING THAT INCIDENT ALL WAS WORKING INCLUDING BRAKES, RADIO AND STEERING. I PROCEEDED TO DRIFT INTO A DRIVEWAY TO STOP THE CAR FOR HELP, GOOD THING I WAS NOT ON THE FREEWAY COULD HAVE GOTTEN KILLED. THE CAR IS GETTING SERVICED NOW, I DO NOT WANT IT BACK, WILL TRADE IN FOR DIFFERENT MAKE/MODEL IS THIS CONSIDERED A LEMON AND WHICH LAWS/ACTION DO I TAKE? I'VE ONLY HAD THE CAR ONLY 7 MONTHS WHEN THIS STARTED TO HAPPEN.
