I still have more to add to my other complaint. The fire started with alternator apparently there were crossed wires took alternator back to Orielys where I got it warrented out fixed the expanded wiring and replaced a hose and other things damaged by the little fire. Then after that things kept getting worse. Then it was spark plugs that were rusted that I replaced eventually I complained back to the dealership I got the car from and they agreed to help repair it after a posting by me on fb that I wasent a happy customer basically and that I literally had a sitting duck. Turns out the timing chain needed to be replaced and other little things. I've replaced O2 sensors camshaft sensors gaskets in catalytic converter had it inspected thinking it was a clogged exhaust the excessive oil usage was insane I would be going through 5quarts twice a month! I'm just tryna have a DECENT WORKING VEHICLE for my kids and I. I literally can't keep a job because I DONT HAVE RELIABLE transportation....I've put sooooo much money into this vehicle and now I might have a blown gasket!!! And that's because I haven't even been driving the vehicle. I got the car on Jan 7th 2021 with 129,043 miles on it as of today it has a total of 164,627 miles on it meaning in between the two years that I've owned the vehicle I have only put a total of 35,584 miles on it.....for it to have this many problems for so little mileage is INSANE!!! my kids were in the car with me today when the car started smoking like crazy from under hood and exhaust I pulled over turned the car off and took my baby off car seat in all and got away from vehicle thinking it was on fire again. I popped the hood and notice it was coming from under manifold.....meaning its probly a blown gasket after I just replaced the camshaft sensor AGAIN......it's ridiculous all the stuff thats going wrong with this vehicle with so little mileage that's been put on it.

First off before I got the car it had gone through a tune up. About a couple months after I got the car little things started to happen it would rock back and forth while idling I thought it was kind of an indicator that it needed oil but the percentage was still at a decent range and telling me it didn't need oil plus I hadent driven it 3000-5000 miles. Then engine light came on had it inspected codes ran came back telling me something about Throttle body So I purchased a whole new throttle body in Prosser at dealership costing me some booko buks and swapped it out when I got back home I then took it for test drive along with my 4 kids in the vehicle with me and then a little ways about 20 mins driving engine power reduced light came on along with stabilitrak and eventually lost power I was stranded in the middle of summer in the middle of nowhere with my kids windows rolled down ppl drove by and asked if I needed help and eventually came back with jumper cables tried to jump me but the car wouldn't budge I then left the car there overnight and took battery out to have it inspected the next day IT WAS FRIED (over 4 yrs old) so I had to purchase a new one costing me roughly 150 buks then took it back to where my car was stranded put it in and alarm went off and I clicked the button on key ring stuck it in ignition shit the door behind me locking keys in car while vehicle was still running and had to bust a window out to get to em. Got into car drove off made it back to my apt left it running outside while I went inside to get some stuff before I THOUGHT the problem was solved it shut off again.....I then had to replace the alternator costing me another pretty penny....about a couple weeks later I was starting a new job at a assisted living facility and arrived 10 mins early shit car off a noticed smoke coming from under hood I was confused because where the smoke was coming from couldn't have been it overheating I popped the hood and my car was on fire!!!!

Once again, timing chain incident, this time while driving, wasn't expecting it, suddenly my Terrain steering when became stiff to turn, and happened to realize the car motor had shut off and rolling to the right, nearly hitting parked car. I tried to start vehicle, but made a whining sound, but did not start, yet check engine light was on. I had my OBD reader handy, and got p0011, p0017 codes, which tell me it was the timing chain again in this car. This very dangerous because we could of collided with a parked vehicle, if not for me struggling so hard to steer vehicle while steering wheel was stiff.

Over the past couple years I have become worried to even drive this vehicle. Well Taken care of and maintenance completed regularly. This vehicle has been in the shop 7 times in the past couple years but no one can tell me exactly what is going on. Only 1 place has told me that I need extensive electrical work but couldn't tell me what exactly the problem was. Issue #1: When coming to a stop, and/or idle, the engine seems to give up and vehicle shuts off. Issue #2: When started Engine sounds like a.high pitch raddle. Issue #3: Occasionally, while driving on the interstate going around 60 - 65 mph the electrical inside the vehicle will flash and everything shuts off and the emergency brake is applied automatically. This has become dangerous - if I wasn't wearing a seatbelt I could have been thrown through the windshield. Issue #4: Replace Fuel Cap Sensor comes on even though it's been replaced. Issue #5: Engine Power Reduced notification comes on even though it had a new battery and alternator. Issue #6: Occasionally Speakers sound blown and you can hear a buzzing as you accelerate. Issue #7: Stabili Track, ABS, and TPMS Sensors all come on at once and go away at once atleast 4 times a week. Issue #7: Rear Cam doesn't always work, sometime either black or static looking. Issue #8: Sometimes key sticks in ignitiin and will not turn on unless being jumped by another vehicle. Issue #9: Often upon starting the whole dash goes black and will stay that way for several hours then comes back on. I've checked all fuses and multiple mechanics can't figure it out. As time goes by without repair I'm scared to even drive this vehicle. Why can't someone figure this out!!

VEHICLE BEGAN TO USE EXCESSIVE AMOUNT OF OIL AND IDEL UP AND DOWN AND SOMETIMES EVEN SHUTS DOWN. AFTER ABOUT 3 MONTHS WHILE DRIVING ON THE INTERSTATE IT BEGAN TO SHUT DOWN WHILE IN MOTION. I CALLED FOR SOMEONE TO CHECK THE VEHICLE OUT AND HE ARRIVED CALLED SOMEONE TO CHECK THE VEHICLE AND HE ACTUALLY TOLD ME IT SEEMS TO BE THE MOTOR GONE BAD BUT HE ASKED WOULD I DRIVE IT BACK HOME IF HE FOLLOWED BEHIND. IT LITERALLY SCARED ME AND MY 4 CHILDREN TO DEATH WHEN IT SHUT DOWN WHILE IN MOTION WITH THAT KIND OF SPEED SO I DON'T TRUST PUTTING MY CHILDREN IN IT NOW. I DON'T THINK ITS SAFE AT ALL. THE VEHICLE I ONCE THOUGHT WAS PERFECT FOR MY FAMILY IS TURNING OUT TO BE A NIGHTMARE.

SEVERAL TIMES IN 3 YEARS, THE DEALERSHIP CAN NOT DUPLICATE THE PROBLEM LOSS OF POWER STARTS RUNNING SLOW, WONT GO OVER 20 MPH, CHECK STABILITY LIGHT COMES ON, CHECK ENGINE LIGHT STARTS BLINKING, ACTS LIKE MISFIRE OR NO FUEL IN VEHICLE, STARTS ANYWHERE AT ANY TIME, VERY UNSAFE AND SCARY. AT LEAST TAKEN TO A CERTIFIED DEALERSHIP 7 OR 8 TIMES AND EVERY TIME THEY DO SOMETHING DIFFERANT , YET THE PROBLEM PERSISTS! THE VEHICLE CAN BE STATIONARY AT RED LIGHT AND BIG OR WHILE DRIVING GOING 45 OR 65 AND DROP TO 20 MPH AND NOT WANT TO GO, I PUSH THE GAS PADDLE TO FLOOR AND IT DOES NOTHING. THIS HAS BEEN INTERMEDIATE AND A PROBLEM SINCE MONTH 3 OF BUYING MY VEHICLE. THIS IS NOT SAFE AND THE DEALERSHIP HAS BASICALLY GIVIN UP ON ME AND MY VEHICLE.

I EXPERIENCING PROBLEMS WITH MY GMC TERRAIN. I HAVE CONTACTED MY LOCAL DEALER (DORAL GMC, IN MIAMI, FL) ON MULTIPLE OCCASIONS WITH NO RESPONSE. I HAVE SUBMITTED A WRITTEN COMPLAINT TO GMC ON APRIL 10TH, 2012 AND NEVER RECEIVED A REPLY. I'VE EXPERIENCED CONTINUOUS CAR PROBLEMS SINCE THE PURCHASE OF MY VEHICLE. WITHIN THE FIRST 3 MONTHS OF PURCHASE MY CAR HAD ALREADY BEEN KEPT AT THE DEALER FOR 30 DAYS ON 2 SEPARATE OCCASIONS. VEHICLE PROBLEMS WERE, FOR EXAMPLE; THE AIRBAG SERVICE LIGHT TURNED ON, CAR TURNED OFF WHILE DRIVING ON A HIGHWAY, THIS ISSUE WAS TAKEN CARE OF BUT RETURNED SEVERAL TIMES TO HAVE IT CORRECTED AS IT KEPT HAPPENING. THE VEHICLE ALSO EXPERIENCED TRANSMISSION ISSUES, THE CHECK ENGINE LIGHT ALSO KEPT TURNING ON AND SERVICE DEPARTMENT COULDN'T FIGURE ANYTHING OUT WITH MY VEHICLE.THIS WAS MY FIRST GMC PURCHASE AND IT HAS BEEN MY ABSOLUTE WORST EXPERIENCE WITH ANY AMERICAN CAR COMPANY. THE LATEST ISSUE SINCE DECEMBER OF 2017 HAS BEEN THE AIRBAG SERVICE LIGHT ONCE AGAIN AND THE STABILITY TRACK LIGHT. I TOOK THE VEHICLE IN FOR SERVICE ONCE AGAIN AND I WAS CHARGED FOR DIAGNOSTIC SERVICE SO THAT THE ISSUE COULD BE FOUND FOR EACH ISSUE AND WAS TOLD I WOULD HAVE TO PAY $135.00 PER ISSUE. I ONLY PAID FOR THE AIRBAG ISSUE SINCE IT SEEMED TO BE THE MOST DANGEROUS ONE AND WAS TOLD BY SERVICE DEPARTMENT THAT THE MODULE KIT NEEDED TO BE REPLACED. THIS NEW CHARGE WAS $ 823.90 THAT I HAD TO PAY OUT OF POCKET. THIS ISSUE SEEMS TO BE A FACTORY ONE AND I WOULD LIKE TO BE REIMBURSED SINCE THIS IS A SAFETY FEATURE THAT SHOULD NOT HAVE HAPPENED. I'VE NEVER HAD AN ACCIDENT AND HAVE KEPT IT SERVICED AND WELL MAINTAINED AT THE DEALER THROUGH OUT ALL THE RECALLS AND SERVICE PROBLEMS. THE REASON I PAID FOR THIS SERVICE WAS MAINLY FOR THE SAFETY OF MY FAMILY BUT ONCE AGAIN, IT'S AN INCONVENIENCE.

WHILE DRIVING THE VEHICLE, I EXPERIENCED STRONG KNOCKING VIBRATIONS AND SOUNDS SEEMINGLY COMING THROUGH THE FLOORBOARD. AS I CONTINUED DRIVING FOR ABOUT 5 MILES TRYING TO GET HOME, THE KNOCKING BECAME MORE PRONOUNCED AND MY STEERING WAS AFFECTED. I ALSO BEGAN NOTICING AN EXTREMELY STRONG ODOR NECESSITATING LOWERING WINDOWS TO BREATHE. I NOTIFIED MY DEALERSHIP AND TOOK THE VEHICLE IN FOR DIAGNOSIS THE VERY NEXT MORNING WITHOUT DRIVING IT AFTER ARRIVING TO MY GARAGE. I WAS TOLD THE AWD HAD COMPLETELY DETERIORATED. MY CONCERN WAS THAT I NEVER RECEIVED ANY DASHBOARD NOTIFICATION OF THE PROBLEM, NOT DID MY ONSTAR DIAGNOSIS INDICATE A PROBLEM. I HAVE BEEN QUITE DISTURBED THAT THE VEHICLE BECAME DISABLED BEFORE I WAS AWARE OF ANY PROBLEM. I HAVE TAKEN MY VEHICLE IN FOR REGULAR MAINTENANCE AT MY GMC DEALERSHIP AND WOULD LIKE AN EXPLANATION REGARDING THE FAILURE TO IDENTIFY THIS PROBLEM THROUGH THE REGULAR MAINTENANCE CHECKS. I AM SINGLE SENIOR WOMAN WHO HAS NO BACKUP VEHICLE AND AM QUITE CONCERNED ABOUT MY SAFETY ON THE HIGHWAY AND THIS ISSUE HAS CAUSED ME TO HAVE SERIOUS SAFETY CONCERNS. I DROVE THE CAR TO THE DEALERSHIP TO CHECK ON THE PROBLEM ON FRIDAY, FEBRUARY 16, 2018. I CALLED THE GMC COMPLAINT CENTER TO CHECK ON POSSIBLE RECALLS OR ANY REMAINING WARRANTIES THAT MIGHT APPLY AND I WAS TOLD THE CENTER WAS ASSIGNING A SR. ADVISOR TO CONTACT THE LOCAL GMC DEALERSHIP THAT STILL HAS MY CAR AND THE ADVISOR WAS TOLD THE DEALERSHIP NEEDED MORE TIME TO DIAGNOSE AND ASSESS THE CAUSE OF THE PROBLEM.I HAVE HAD TO RENT A VEHICLE SINCE IT MAY BE ANOTHER 2-3 DAYS BEFORE I EVEN GET A RESPONSE REGARDING THE NATURE AND COST OF THE REPAIRS. I WAS ORIGINALLY TOLD THE ENTIRE AWD SYSTEM HAD TO BE REPLACED AT A COST OF $1500--$2000. I QUESTIONED THE REASON FOR THE EXTREME MALFUNCTION WITHOUT ANY WARNING NOTICES APPEARING...MAIN REASON FOR MY COMPLAINT AND CONCERN.

MY CHECK ENGINE LIGHT CAME ON ABOUT A MONTH AGO AND WAS SERVICED FOR A PROBLEM WITH THE CAMSHAFT. AFTER GETTING MY GMC TERRAIN BACK I NOTICED THAT ON OCCASION THE RPM WOULD SHOOT UP WHILE DRIVING AND THEN CRASH BACK DOWN CAUSING ALMOST A JERKING MOTION (IT HAS HAPPENED IN ALL TYPES OF SCENARIOS I.E. WHILE DRIVING ON THE HIGHWAY, BACK ROADS (ALL WHILE AT A STEADY SPEED) AND THEN FINALLY YESTERDAY 3/5/2016 WHILE BREAKING AS I APPROACHED A STOP SIGN.) NOW THIS MORNING (3/6/2016) I WENT OUT TO START MY CAR AND IMMEDIATELY AFTER IT TURNED OVER THE ENGINE WAS MAKING A VERY LOUD NOISE THAT I CAN ONLY DESCRIBE AS THE SOUND OF AN AIRPLANE ENGINE WITH A LIGHT KNOCKING SOUND. I STOOD THERE UNSURE OF WHAT TO DO AND THE CAR JUST TURNED OFF. I WENT INSIDE, GOT MY HUSBAND, STARTED IT AGAIN THIS TIME WITHOUT THE NOISE, BUT THE DASHBOARD WAS FILLED WITH LIGHTS ON- CHECK ENGINE, TRACTION CONTROL, AND A WARNING SERVICE STABILITRACK. I LET IT RUN FOR ABOUT 5 MINUTES, TURNED IT OFF, AND RESTARTED IT. THE CHECK ENGINE LIGHT IS NOW OFF, BUT THE TRACTION CONTROL AND STABILITRAK WARNING REMAINED ON. I DECIDED TO TRY TO DRIVE THE CAR AROUND THE BLOCK TO CHECK IT OUT AS OF COURSE IT'S SUNDAY AND I CAN'T GET IN TOUCH WITH THE SERVICE DEPARTMENT AND ALSO BECAUSE I AM THE PRIMARY DRIVER OF TWO CHILDREN UNDER 10. I BACKED OUT OF THE DRIVEWAY, AND WENT INTO DRIVE AND THE CAR STALLED AGAIN. I GOT IT STARTED AND GOT HALFWAY BACK UP MY DRIVEWAY BEFORE IT STALLED AGAIN. TRUTHFULLY, I AM SCARED TO EVEN TRY TO DRIVE IT NOW, AND IF I AM BEING HONEST I DON'T THINK THAT THE CAR WILL MAKE IT TO THE DEALERSHIP (1HR. AWAY BY HIGHWAY) WITHOUT STALLING. I'VE NOTICED OTHERS WITH SIMILAR COMPLAINTS ON GM/CHEVY ALL MAKES AND MODELS, AND DON'T UNDERSTAND WHY THIS ISSUE IS NOT BEING RESOLVED. WHAT ARE THEY WAITING FOR- A FAMILY OF 4 DRIVING ON A HIGHWAY CAUSING AN ACCIDENT BECAUSE THEIR CAR STALLED? DEATH?

I HAVE HAD ISSUES WITH THIS VEHICLE EVER SINCE ITS PURCHASE 01/2015. I TOOK THE VEHICLE IN FOR SERVICE AND WAS TOLD THE SERVICE CONTRACT WOULD NOT COVER MY ISSUE AND THAT THE ISSUE WAS CAUSED BY LACK OF MAINTENANCE, WHICH IS NOT THE CASE AS I MAINTAIN THE OIL IN THIS VEHICLE AND EVEN HAD TO PURCHASE A NEW BATTERY FOR THE VEHICLE RECENTLY.THIS CAR'S ENGINE REPEATEDLY STOPS, ESPECIALLY WHEN APPROACHING A RED LIGHT OR STOP SIGN OR AT THE MOMENT OF ACCELERATION. I HAVE HAD TO AVOID MANY ACCIDENTS DUE TO PEOPLE DRIVING UP ON ME BECAUSE I SHOULD HAVE BEEN ACCELERATING AT THE TIME BUT MY CAR TURNED OFF. THE BATTERY WOULD DIE ON THIS CAR ON A WEEKLY BASIS WHICH CAUSED ME TO PURCHASE A BATTERY AND THERE IS STILL NO PROGRESS IN THE VEHICLE. THE MOTOR KNOCKS BADLY UPON STARTUP, ESPECIALLY IN THE MORNINGS. THE ENGINE IS VERY WEAK AFTER AN INDEPENDENT DIAGNOSTIC CHECK. AND JUST LAST WEEK, AS I WAS DRIVING ON THE HIGHWAY AT NORMAL SPEEDS, THE MUFFLER SHIELD BROKE, FELL, AND BEGAN SCRAPING AGAINST THE HIGHWAY. THERE ARE ELECTRICAL ISSUES AS WELL AS THE LIGHTING IN THE CAR GETS DIM WHEN WE ARE IN THE DARK BUT BRIGHT WHEN THE SUN IS OUT. ALSO, THE SEATBELT FOR THE PASSENGER'S SIDE CONSTANTLY RINGS SENDING A NOTIFICATION THAT THE SEATBELT NEEDS TO BE LATCHED, EVEN WHEN NO ONE ELSE OR NOTHING ELSE IS IN THAT SEAT. I FEAR THAT ONE DAY I MAY NEED THAT AIR BAG AND IT MIGHT NOT WORK BECAUSE THE SEATBELT APPEARS TO BE FAULTY. ALSO, ANOTHER ISSUE, WHICH IS NOT NECESSARILY A SAFETY ISSUE, BUT AN EXTREME NUISANCE AND ALSO MAYBE AN ELECTRICAL ISSUE IS THE CAR RADIO AND VOLUME WILL FREEZE AT ANY GIVEN MOMENT AND THE CAR HAS TO BE STOPPED AND IDLE FOR A PERIOD OF TIME BEFORE THE RADIO IS ACTIVE AND ABLE TO TURN CHANNELS AGAIN. THE SAFETY ISSUES FOR THIS CAR ARE REAL AND I AM IN FEAR THAT I WILL GET HIT FROM BEHIND DUE TO THE FAULTY ENGINE.

ON 8/2/12 I PURCHASED MY GMC TERRAIN BRAND NEW IN ASHLAND CITY, TN. I MOVED TO WEST PALM BEACH IN OCTOBER 2012. THE CURRENT MILES ON THE VEHICLE ARE 44,039. I GOT AN OIL CHANGE, FILTER AND MULTI-POINT INSPECTION ON 10/24/13 BY THE LOCAL GMC DEALER. ON 10/23/13 I TOOK MY VEHICLE IN TO HAVE A RECALL REPAIRED AT SCHUMACHER BUICK/GMC. THE RECALL # IS 12312. A MONTH LATER THE VEHICLE WOULD LUNGE SHARPLY FORWARD WHILE DRIVING AND A HEAVY SHAKING VIBRATION (BOTH WHILE DRIVING AND AT A STOP) BELOW MY FEET IN THE VEHICLE (FLOOR BOARD). I TOOK THE VEHICLE TO SCHUMACHER BUICK/GMC 3031 OKEECHOBEE BLVD, ON 11/11/13 AND IT REMAINED UNTIL 11/15/14 AND THE PROBLEM WAS NOT IDENTIFIED. I RETURNED THE VEHICLE FOR THE SAME PROBLEM ON 12/21/13 (SAME DEALER) AND IT WAS PICKED UP ON 12/31/13. THE FIRST SERVICE ADVISOR WAS ROB DEAL HE TOLD ME THAT THE VEHICLE SHIFTS ITS DRIVABILITY TO THE DRIVER AND NOTHING WAS WRONG. I TOOK MY VEHICLE BACK A SECOND TIME FOR THE SAME PROBLEM THIS TIME (IT WAS GETTING WORST) MY REP WAS "[XXX]". HE SAID IT WAS THE "ECO" BUTTON IN THE CAR, IF PUSHED MAKES THE CAR RUN ROUGH." ON MARCH 7, 2014, I CONTACTED GMC CORPORATE OFFICE AND SPOKE TO SHERRY AND REQUESTED A FULL ANALYSIS OF MY CAR. THIS TIME I WENT TO ANOTHER GMC DEALER LOCALLY (LAKE PARK SCHUMACHER) AND MY SERVICE TECH WAS [XXX]. PER [XXX] IT IS A TRANSMISSION ISSUE -LEFT ON MY VOICEMAIL AND SAVED" SPECIFICALLY HE SAID IT WAS THE "CONTROL PRESSURE VALVE CAUSING IT TO LUNGE FORWARD AND IT WAS IMPROPER." HE SAID IT WAS "UNCOMMON TO SEE THIS ISSUE." THE REASON I TOOK THE VEHICLE IN IS THAT I ALMOST REAR ENDED TWO PEOPLE WHILE DRIVING DUE TO THE VEHICLES LUNGES AND HAVE MY BODY JOLTED INTO THE GLASS THE FORCE WAS SO STRONG WITH THE LUNGE. I FEAR FOR MY SAFETY AND THAT OF MY 12 YEAR OLD DAUGHTER IN THIS CAR. I WAS CONTACTED ON 3/13/14 THAT THE VEHICLE WAS READY FOR PICK-UP AND IT HAD BEEN FIXED.

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
