2012 GMC TERRAIN Complaints

I OWN A 2012 TERRAIN SLE2 WITH APPROXIMATELY 20,000 MILES. ON FRIDAY, DECEMBER 13, 2013, I JOINED THE INNUMERABLE OWNERS OF GM PRODUCTS (FOUND ON THE VARIOUS OWNER FORUMS ON THE INTERNET) THAT HAVE EXPERIENCED THE SERVICE STABILITRAK LIGHT COMING ON WITH ROUGH IDLING. OTHER OWNERS HAVE EXPRESSED THE LOSS OF POWER WHEN THIS EVENT OCCURS. LUCKILY, I WAS BACKING OUT OF MY GARAGE AND NOT TRAVELING ON THE EXPRESSWAY SO I CANNOT ADVISE WHETHER THERE WAS LOSS OF POWER SINCE I WAS GOING SO SLOW. THE LIGHT WENT OFF WHEN I TURNED THE VEHICLE OFF IN ORDER TO COME INSIDE AND CALL THE DEALER (WOODY BUICK GMC IN NAPERVILLE IL). THE DEALER WAS ABLE TO FIND CODE PO300 (RANDOM CYLINDER MISFIRE) BUT THEY COULD FIND NOTHING WRONG. I WAS TOLD THE VEHICLE FIXED ITSELF (WHICH I FIND HIGHLY DOUBTFUL AND VERY DISTURBING). I AM A ONE VEHICLE FAMILY AND NOW IN A COMPLETE PANIC WHENEVER I DRIVE THIS VEHICLE. I FEAR FOR MY LIFE, MY PASSENGERS? AND OTHERS BECAUSE LOSS OF POWER CAN HAPPEN AT ANY TIME AND I AM CONCERNED ABOUT BEING REAR ENDED SINCE THE DRIVER BEHIND ME WOULD HAVE NO CLUE, AS I DON?T, THAT MY VEHICLE WILL LOSE POWER. SINCE THIS IS A HUGE SAFETY CONCERN, I AM SHOCKED THAT GM HAS NOT ADDRESSED THIS FAILURE OF ITS PRODUCTS. *TR

THE VEHICLE HAS BEEN IN THE SHOP FOR 10 TO 12 TIMES DUE TO FAILURE WITH THE ENGINE MISFIRING AS WELL AS TRACTION CONTROL LIGHTS AND STABILITY TRAC AS WELL AS TRANSMISSION NOT SHIFTING RIGHT AND LOSS OF POWER WHILE DRIVING ON MAJOR HIGHWAYS AND BROUGHT INTO THE DEALERSHIP WHERE THEY TELL ME THEY CAN FIND OR MAKE THE PROBLEM REAPPEAR. BUT HAVE SHOWN THE DEALERSHIP SERVICE DEPARTMENT VIDEO AND HAVE HAD 3 GENERAL MOTOR TECHS THAT THEY HIRED FROM HP AND BEEN TOLD THE VEHICLE IS SAFE AND THAT THERE WILL BE NO MORE PROBLEMS BUT HAVE BEEN IN THE VEHICLE WHILE THE PROBLEMS HAVE HAPPENED AND HAVE IT ON VIDEO TO THE POINT WHERE I ALMOST LOST MY LIFE YESTERDAY NIGHT. THE VEHICLE IS A DEATH TRAP AND MANY CUSTOMERS INCLUDING MYSELF ON GMC TERRAIN FORUM AS WELL AS ONLINE HAVE HAD THE SAME PROBLEM AND HAVE BEEN TOLD THE SAME THING THAT IT IS NOTHING TO WORRY ABOUT BUT IT IS. PLEASE HELP HAVE BEEN TOLD BY GM TO KEEP MY MOUTH SHUT THEY WOULD OFFER ME 5,000 DOLLARS FOR MY TROUBLES AND THAT MY KIDS ARE WORTH THAT MUCH FROM A LEGAL ADVISOR AT GENERAL MOTORS LEGAL. HAVE ASK TO BE TAKING OUT OF THE VEHICLE FOR SOMETHING SAFE AND STILL I'M BEING TOLD NO......PLEASE HELP

AFTER STOPPING AT MAILBOX THE LOW FUEL ILLUMINATED, THE FUEL GAUGE INDICATED EMPTY. THE TANK WAS HALF FULL PRIOR TO THE 12 MILE TRIP HOME FROM TOWN. NOT SURE WHEN THE PROBLEM OCCURRED, BECAUSE IT MIGHT HAVE TAKEN A FEW MINUTES TO PUMP OUT 8 OR 9 GALLONS OF GAS, HOWEVER IT WAS ON THIS12 MILE TRIP HOME. 6 MILES OF HIGHWAY AT 55 MPH AND 5 MILES OF PAVED COUNTY ROAD AT 30 MPH AND 1 MILE OF GRAVEL ROAD AT 20 MPH. AFTER THE LOW FUEL INDICATION THE ENGINE WAS STOPPED, FUEL WAS ADDED FROM A CONTAINER, AND WHEN THE ENGINE WAS STARTED THE FUEL STREAMED OUT ON THE GROUND. THE VEHICLE WAS TOWED TO A LOCAL REPAIR FACILITY, BECAUSE IT WAS CLOSER THAN THE DEALER. GAS LINE AND CLAMP WERE REPLACED. THE MECHANIC INDICATED THE PLASTIC GAS LINE AND PLASTIC CLAMP WERE HANGING LOW, AND NO PROTECTIVE COVE OVER IT. *TR

VEHICLE'S TRANSMISSION SLIPS AND DOES NOT RESPOND TO AN ACCELERATION AFTER A RAPID DECELERATION OF AT LEAST 40 MPH. THE VEHICLE WILL JERK IN RESPONSE TO YOUR ATTEMPT TO ACCELERATE AND THEN WILL RESPOND. THIS CAN LEAD TO A DANGEROUS SITUATION IF YOU ARE ATTEMPTING TO AVOID A COLLISION BY ACCELERATING TO GET OUT OF THE WAY. *TR

TL* THE CONTACT OWNS A 2012 GMC TERRAIN. THE CONTACT STATED THAT WHILE SITTING AT A TRAFFIC STOP, A SEMI-TRUCK CRASHED INTO THE REAR BUMPER OF THE CONTACT'S VEHICLE. THE CONTACT'S VEHICLE WAS PUSHED FORWARD, CAUSING THE CONTACT TO CRASH INTO A PRECEDING VEHICLE. THE AIR BAGS FAILED TO DEPLOY. THE CONTACT SUSTAINED INJURIES TO THE HAND, NECK AND BACK. A POLICE REPORT WAS FILED. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC FOR DIAGNOSIS BUT THEY WERE UNABLE TO DUPLICATE THE AIR BAG DEPLOYMENT FAILURE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 32,000. *TR

VEHICLE WAS INVOLVED IN A CAR ACCIDENT AND CRASHED INTO A BRIDGE IRON BEAM HEAD-ON. VEHICLE'S AIR BAGS FAILED TO DEPLOY. HOOD AND FRONT OF CAR SMASHED AS VEHICLE WAS WRAPPED AROUND BEAM. ONLY MINOR INJURIES TO DRIVER, AS DRIVER WAS WEARING A SEATBELT. *TR

I STARTED OUT DRIVING ON HIGHWAY ROAD AT APPROXIMATELY 5:45PM TRAFFIC WAS MODERATE, MY SPEED WAS ABOUT 30-35 MPH. ALL OF A SUDDEN I HEARD A CLUNK AND THEN ALARM DING FROM THE DASH AS WELL AS MESSAGE "SERVICE STABILTRAK" THEN "REDUCED ENGINE POWER". I WAS UNABLE TO GO ANY FASTER THAN 25MPH. I DROVE IN THIS MODE FOR ABOUT 2 MILES IN TRAFFIC, WHEN REACHING OPEN HIGHWAY (NO TRAFFIC) THE VEHICLE WOULD NOT SHIFT BY ITSELF. I HAD TO ACCELERATE THEN LET OFF THE GAS, TAP PEDAL THEN THE VEHICLE WOULD SHIFT. I WAS ABLE TO DO THIS MULTIPLE TIMES UNTIL REACHING ABOUT 45MPH. I PULLED OFF INTO A NEIGHBORHOOD, SHUT VEHICLE OFF TO SEE IF THIS WOULD RESET SOMETHING, IT DID NOT. THE VEHICLE WAS IN THIS STATE WHEN I ARRIVED AT THE DEALERSHIP SERVICE DEPARTMENT AT APPROXIMATELY 6:05PM. DEALERSHIP LOGGED FOLLOWING ON SERVICE REQUEST: 5043 FOUND CODE P228C RAN DIAG COULD NOT DUPLICATE PROBLEM FUEL PSI AT SPEC RAISES TO SPEC TEST DROVE ON HIGHWAY DID NOT DUPLICATE CONDITION FOUND NO BULL ON CONDITION TEST DRIVE NUMEROUS TIME, COULD NOT DUPLICATE CONCERN. MILES OUT 5067. *TR

THE DATA I ENTERED FOR "FAILURE MILEAGE" AND "SPEED AT TIME OF INCIDENT" SHOULD NOT BE USED AS CONCRETE DATA BECAUSE FOR THE MOST PART FROM ROLLING UP VERY SLOW DRIVING WOULD BE MORE ACCURATE (WITHOUT GIVING GAS). I AM 47, AND DRIVING SINCE 18. I AM A MECHANIC, WORKED TELEPHONE, DATA, PRESENTLY A NURSE. I HAVE DRIVEN MANY CARS. I HAVE OWNED, OR CO-OWNED A LEAST 15 CARS. I AM ALWAYS ON THE ROAD IN ALL CONDITIONS. ALL MY PAST PROFESSIONS REQUIRED PLENTY DRIVING. I HAVE DRIVEN THE ABOVE MENTIONED VEHICLE FOR LITTLE OVER 2 MONTHS. THERE IS A SIGNIFICANT BLIND SPOT TO THE FRONT RIGHT- WHERE THE FRONT MIRROR JOIN THE FRONT RIGHT DOOR STRUCTURE. TO TURN RIGHT FROM A STOP SIGN, OR A STOP LIGHT, IS DANGEROUS. THE VERTICAL SHAFT (RIGHT SIDE EDGE OF THE WIND-SHIELD VIEWED FROM DRIVERS SEAT) COUPLED WITH THE LARGE MIRROR MAKE FOR A SIGNIFICANT BLIND SPOT. I HAVE HAD TWO OCCASIONS OF NEAR MISSES (I MAKING A RIGHT TURN FROM STANDING / PEDESTRIAN ON SIDEWALK TO MY RIGHT ATTEMPTING TO CROSS STREET / PEDESTRIAN CROSSING DRIVERS RIGHT TO LEFT). FINALLY IT HAPPENED; SHE WAS 71 YRS OLD. I HAVE TESTED MY THEORY OVER AND OVER. I AM CHANGING THE CAR. IT BLOCKS TOO MUCH MASS. I CAN BLOCK-OUT THE ENTIRE FRONT TIRE OF A CITY BUS IF IT IS TO MY RIGHT AT A RED LIGHT OR STOP SIGN; THAT IS SIGNIFICANT. AS THE DRIVER SCANS FROM LEFT TO RIGHT BEFORE A RIGHT TURN, AND AS THE PEDESTRIAN MOVES TO CROSS, THE PEDESTRIAN CAN DISAPPEAR OUT OF VIEW- NOW THAT IS DANGEROUS (MEANWHILE THE PEDESTRIAN IS THINKING THAT THE DRIVER SEES HIM/HER AND EXPECTS THE DRIVER TO EVENTUALLY STOP). BUT, AT THE SAME TIME DRIVER NEVER SEES PEDESTRIAN DUE TO THAT FRONT BLIND SPOT. NOW,AS DRIVER LIFTS OFF BRAKES AND ROLLS FORWARD, THE DANGER COMES AS BOTH DRIVER AND PEDESTRIAN ARCH TO PERPENDICULAR TO EACH OTHER. THE BLIND SPOT TRAVELS WITH DRIVER. *TR

TL* THE CONTACT OWNS A 2012 GMC TERRAIN. THE CONTACT STATED THAT HE WAS DRIVING APPROXIMATELY 60-70 MPH WHEN HE HEARD A LOUD NOISE AS THE VEHICLE STALLED. THE CONTACT WAS ABLE TO PULL OFF THE ROAD. AFTER INSPECTING THE VEHICLE, HE FOUND THAT THE FUEL LINE WAS FRACTURED AND ALL OF THE GASOLINE SPILLED OUT FROM THE VEHICLE AND ONTO THE HIGHWAY. THE POLICE WERE CONTACTED AND A REPORT WAS FILED. THE VEHICLE WAS TOWED TO THE DEALER FOR DIAGNOSIS WHERE THE CONTACT WAS ADVISED THAT THE FUEL LINE NEEDED TO BE REPLACED. THE FUEL LINE WAS REPLACED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE AND CURRENT MILEAGES WERE APPROXIMATELY 12,000.

THE HEADLIGHT SYSTEM ON THIS VEHICLE LEAVES A LOT TO BE DESIRED. THE HEADLIGHTS ARE VEILED SOMEHOW SO THAT THERE IS NO ILLUMINATION ABOVE THE HEADLIGHTS WITH LOW BEAM. WHEN DRIVING IN HILLY AREAS, THE FORWARD PROJECTION OF THE HEADLIGHTS IS VERY LIMITED WHEN TRAVELING DOWN HILL. THE HI BEAMS ILLUMINATE WELL, BUT WHEN DRIVING IN THE COUNTRY WITH ONCOMING TRAFFIC AND LOW BEAMS IN HILLY AREAS, THE VIEW OF THE SIDE OF THE ROAD AHEAD IS VERY RESTRICTED. IF I HAD DRIVEN THIS VEHICLE AT NIGHT BEFORE I BOUGHT IT, I DOUBT THAT I WOULD HAVE BOUGHT IT, IT'S THAT BAD. *TR
