2017 GMC Terrain Owner Complaints

MY CHECK ENGINE LIGHT CAME ON ALONG WITH A A MESSAGE THAT STATES 'REDUCED ENGINE POWER' AND A MESSAGE READING 'SERVICE STABILITREK WHEN I WAS DRIVING ON THE HIGHWAY AT 70 MPH. THIS CREATED SUDDENLY JERKING AND SLOW ACCELERATION SO THAT I HAD TO PULL OFF THE ROAD. I FOUND A FORUM AT [XXX] THAT REVEALS THAT THIS HAS BEEN AN ISSUE WITH GMC MODES AT LEAST AS LONG AS 2011. THE DURATION FOR WHICH THIS HAS BEEN A PROBLEM WITH GMC MODELS, AND THE FACT THAT STABILITREK IS AN INTEGRAL SAFETY FEATURE OF THE VEHICLE IN AVOIDING ACCIDENTS SEEMS TO MERIT A RECALL.

I HAD MY 2017 GMC TERRAIN DENALI FOR TWO YEARS AND HAVE ALREADY EXPERIENCED TWO SERIOUS ISSUES. ISSUE #1-I NOTICED A BURNING SMELL, GRINDING NOISE, AND HESITATION WHEN DRIVING. I BROUGHT IT TO THE DEALERSHIP WHERE I BOUGHT IT AND WAS TOLD THAT THERE WAS A FACTORY DEFECT WHICH CAUSED SOMETHING INSIDE MY TRANSFER TO BORE A HOLE THROUGH IT. DEALER COULD NOT GET THE PART FOR 2 WEEKS. IT WAS COVERED UNDER MY WARRANTY. A MONTH LATER WHILE GETTING AN OIL CHANGE AT A DIFFERENT AUTO SHOP, I WAS ASKED IF I RECENTLY HAD WORK DONE ONLY TRANSMISSION BECAUSE THE ENTIRE THING WAS LOOSE AND MOVING, AND THE CAR DID NOT DRIVE RIGHT. I WAS TOLD IT WAS NOT SAFE TO DRIVE. I BROUGHT IT BACK TO THE DEALERSHIP AND WAS TOLD THAT THEY COULDN'T FIND ANYTHING. THEY TIGHTENED THE BOLTS ON THE TRANSFER CASE AND CHARGED ME A $60 DIAGNOSTIC FEE (FOR THEIR ERROR). ISSUE #2-AT 63,000 MILES MY WIPERS STOPPED WORKING WHILE I WAS DRIVING AT ABOUT 30MPH ON A BUSY STREET IN THE POURING RAIN (VERY SCARY). I BROUGHT IT TO THE DEALERSHIP AND WAS TOLD I NEEDED A NEW WIPER TRANSMISSION AND WOULD COST $318 BECAUSE MY CAR WAS NOT PART OF THE RECALL. I EXPRESSED CONCERN THAT MY 2YO. CAR HAS NOW HAD TWO SERIOUS SAFETY ISSUES AND WAS TOLD 'CARS HAVE SO MANY MOVING PARTS AND PIECES THAT IT'S A WONDER MORE THINGS WEREN'T WRONG WITH IT'. I DO NOT FEEL SAFE DRIVING THIS CAR AND THE SERVICE MANAGER WAS CONDESCENDING AND COULDN'T CARE LESS. GMC NEEDS TO DO SOMETHING BEFORE SOMEBODY GETS SERIOUSLY HURT OR WORSE.

AT AROUND 20 MILES PER HOUR, WHILE ACCELERATING, ALL TORQUE IS LOST AND THE VEHICLE ENGINE REVS HIGH. IT TAKES A FEW SECONDS, THEN THE TRANSMISSION FINALLY SHIFTS INTO THE NEXT GEAR. THIS CAUSES A BIG JOLT. IT IS DANGEROUS, ALL POWER IS LOST, THEN SUDDENLY TOO MUCH POWER IS APPLIED. THIS HAS HAPPENED SINCE I PURCHASED THE VEHICLE. I HAVE TAKEN IT TO THE DEALERSHIP. THEY WON'T DO ANYTHING ABOUT IT. THE VEHICLE NOW HAS 40,502 MILES.

11/25/2019

OUR NEW TERRAIN HAS "VEHICLE IN FRONT" VISUAL WARNING SYSTEMS. WE WERE FOLLOWING A TANKER TYPE SEMI ON THE INTERSTATE AND PULLED ALL THE WAY UP BEHIND THE TANKER SEMI (WITHIN 25 FT) AND THE VEHICLE IN FRONT LIGHT NEVER CAME ON. WE TESTED THIS ON ALL TYPES OF CARS AND TRUCKS AS WELL AS STANDARD BOX TYPE SEMI AND IT WORKED PERFECTLY. I HAVE PICTURES OF THE REAR END OF THE TANKER SEMI IN WHICH IT DID NOT DETECT AT ALL.

I WAS DRIVING 9PM ON A CITY ST RD, COMING UP ON A MILE LIGHT THAT WAS RED. THE ROADS WERE DRY ON A 5 LANE RD. THERE WAS 1 CAR AHEAD OF MY CAR WITH THEIR BRAKE LIGHTS ON . ALTHOUGH NOT NOTED ON POLICE REPORT THE CAR WAS STOPPED APPROX 5 TO 7 CAR LENGTHS PRIOR TO THE RED LIGHT. I HAD BEGAN TO SLOW DOWN BUT DID NOT REALIZE THE DRIVER AHEAD WAS NOT SLOWING DOWN BUT STOPPED. I SWERVED TO THE RIGHT AND AS NOTED IN PICS BELOW THE DRIVERS SIDE OF CAR HIT THE OTHER DRIVERS PASSENGER BACK CORNER. I ENDED UP IN A PARKING LOT ON THAT CORNER. OTHER THEN THE MEDICAL TERM COOP TO COOP THAT ALSO AIDED IN MY HEAD INJURY, I ALSO HIT MY HEAD 2 TIMES AT MY HAIRLINE ON THE STEERING WHEEL AND THEN MY LEFT CHEEK. I WAS DIAGNOSED AND SUSTAINED A SEVERE CONCUSSION/ BRAIN TRAUMA. I WENT TO THE EMERGENCY ROOM TWICE FOR CARE OF WORSENING SYMPTOMS AND WAS INCAPACITATED AND OUT OF WORK FOR ABOUT 6 WKS. WHICH WAS STILL TO FAST TO RETURN, BUT I COULD NOT AFFORD BEING ON DISABILITY. FOLLOWING THE ACCIDENT THE CAR WAS TAKEN TO THE CITY TOW YARD, AND WAS ASSESSED WITHIN A WEEK BY THE INS ADJUSTER AS TOTAL LOSS. FROM THERE IT WAS TAKEN TO A JUNK SALVAGE BUSINESS. DUE TO MY INCAPACITATION I HAD NO MEANS TO LOOK INTO CONCERNS RELATED TO WHY THE AIRBAGS DID NOT DEPLOY. I AM A NURSE PRACTITIONER THAT NOW HAS SHORT TERM MEMORY LOSS, MIGRAINES, AND ATTENTION DEFICIT DUE TO THE BRAIN INJURY. I HAVE NO WAY OF FINDING OUT IF THE AIRBAG SENSORS WERE DEFECTIVE OR NOT BECAUSE, ALTHOUGH I'M ATTEMPTING TO TRACK THE CAR IT'S BEEN DIFFICULT, AND UNSURE OF MY RIGHTS TO THE CAR IF I CAN TRACK IT DOWN. THE BIGGER SURPRISE WAS THAT I RECEIVED A RECALL NOTICE ON MY 2018 GMC TERRAIN JUST TODAY, BUT HAVE NO ANSWERS ON THE 2017. PLEASE HELP IN ANYWAY WITH WHAT I SHOULD DO. SINCERELY *TR *JS

HEADLIGHTS, HIGH AND LOW BEANS ARE ALMOST USELESS, THEY ARE NOT BRIGHT ENOUGH, BARELY CAN SEE TO DRIVE IT AT NIGHT, ESPECIALLY IF RAINING, TOTALLY ALMOST LIKE BEING BLIND.

The contact owns a 2017 GMC Terrain. The contact was notified through a ridesharing app that the VIN was included in NHTSA Campaign Number: 22V137000 (Exterior Lighting) however, the part to do the recall repair was unavailable. The dealer was made aware of the issue and confirmed that parts were not yet available. The manufacturer was made aware of the issue. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact had not experienced a failure. VIN tool confirms parts not available.

6/17/2022

BLIND SIDE ALERT ACTIVATES WHEN IT IS RAINING AND THERE ARE NO CARS NEARBY. THIS ONLY OCCURS WHEN RAINING. NO CODES ARE THROWN SO DEALER SERVICE WON'T TROUBLESHOOT. THIS CAN ONLY BE REPRODUCED ON A HIGHWAY OR PARKWAY, WHEN IT IS RAINING AND NO OTHER CARS ARE NEARBY. CANNOT BE REPRODUCED ON REGULAR STREETS WITH OTHER CARS AROUND. I'VE HAD MY CAR IN TO THE DEALER SERVICE 3 TIMES, ALL WITH THE SAME RESULTS. NO CODES IN THE COMPUTER AND CANNOT REPRODUCE. THE SERVICE DEPARTMENT ONLY TESTS ON THE LOCAL STREETS. THERE ARE OTHER CARS AROUND, SO HOW CAN THIS BE AN ACCURATE TEST???

6/21/2017

I WAS DRIVING DOWN THE ROAD AT 55 MPH WHEN A DEER RAN OUT AND HIT THE PASSENGER SIDE OF MY VEHICLE. IT BOUNCED AND ROLLED OFF THE DRIVERS SIDE. I PULLED THE VEHICLE OFF TO THE SIDE OF THE ROAD. ALL OF THE ELECTRIC COMPONENTS IN THE VEHICLE WERE ON. THE INTERIOR LIGHTS WERE ON, THE HAZARD LIGHTS WERE FLASHING AND THE CONSOLE WAS LOCKED UP. I PUSHED THE BUTTONS, BUT NOTHING HAPPENED. THE AIRBAGS DID NOT DEPLOY THERE WAS A MESSAGE ON THE SCREEN THAT SAY SERVICE AIRBAG (BUT THEY HADN'T DEPLOYED). I COULD SMELL SOMETHING BURNING, THE VEHICLE WAS SMOKING AND I COULD HEAR SOMETHING POPPING, I GOT OUT TO ASSESS THE DAMAGE AND MY VEHICLE WAS ON FIRE. THE VEHICLE ENDED UP BEING A TOTAL LOSS.. THIS IS HAPPENED IN GA AND THE STATE PATROL DID THE POLICE REPORT.

8/11/2019

TRAVELING ON STATE HIGHWAY 136 BETWEEN 50 AND 55MPH. THE LISTED VEHICLE STRUCK A DEER CAUSING SIGNIFICANT FRONT END DAMAGE. IMMEDIATELY FOLLOWING THERE WAS A VERY STRONG ODOR SIMILAR TO GUN POWDER. THE AIRBAG LIGHT ILLUMINATED AND ON STAR CAME ON LINE IN THE CAR DUE TO CRASH SENSOR NOTIFICATION. HOWEVER, THERE WAS NO AIRBAG DEPLOYMENT.THE ENTIRE FRONT END OF THE CAR SUSTAINED DAMAGE AS WELL AS THE RADIATOR. THE DRIVERS SIDE FRONT QUARTER PANEL ALSO BUCKLED. IT IS UNKNOWN AT THIS TIME OF FURTHER DAMAGE. THE VEHICLE SUSTAINED ENOUGH DAMAGE TO WHERE IT REQUIRED IT TO BE TOWED TO A DEALERSHIP BODY SHOP FOR FURTHER EVALUATION. BASED ON THE FRONT END AND QUARTER PANEL DAMAGE, THERE SHOULD HAVE BEEN AN AIRBAG DEPLOYMENT. THE LISTED VEHICLE IS THE ONLY VEHICLE INVOLVED WITH THE COLLISION. THE GEORGIA STATE PATROL INVESTIGATED AND COMPLETED A CRASH REPORT.

The front passenger seat belt locks on passenger and will not release unless it is completely unbuckled. It keeps doing this for no reason. This was brought to dealer’s attention one to two years ago and they said I would have to pay cost of repair since warranty was off even though I purchased an extended warranty with this vehicle. The service department claims to have taken it apart and cleaned it but could not find problem. The problem is bad since passenger has to unbuckle belt multiple times during a trip.

Rear main oil seal is faulty. It caused the vehicle to leak oil to the point where it was dry. This is a known issue with these vehicles and could have caused catastrophic damage to the engine. Additionally, this can cause the vehicle to stop running and/or catch fire.

2/29/2024

1st time - rear main seal blew out & engine lost all of its oil causing rocker arm to break & chains to slip-vehicle sputtered & DIED while driving down busy street & would not restart - my safety & safety of others driving behind me were at risk for causing a rear end accident and/or pile up crash - no warning lights or sounds alerted me - dealership told us General Motors is aware this is/has been a problem with 2017 Terrain vehicles especially those driven in Midwest states due to colder temperatures - the intake manifold vent hole is not large enough to let air out, so it plugs up & causes pressure to blow out rear seal, which causes oil to leak out and engine dies. When replaced with a remanufactured engine intake manifold vent hole was not drilled out causing it to happen again 2nd time - when leaving parking spot at work noticed oil puddles underneath my vehicle, I checked my oil, it showed full, I was concerned, drove to nearby last place I got my oil change. They informed me that all the oil had leaked out and showed me the bottom of my vehicle oil covered the front to the back of my vehicle. They also said that I was extremely lucky to get to shop before engine blew and stopped dead. AGAIN my safety and safety of others behind me could have been a rear end accident and/or car pileup crash - again no warning lights or sounds alerted me - shop personal told me General Motors is aware this is/has been a problem with 2017 Terrain vehicles especially those driven in Midwest states due to colder temperatures - even though the repairs where done by a certified dealership the first time they replaced with a remanufactured engine but failed to drill out the intake manifold vent hole bigger so this would not happen again BUT IT DID. General Motors cannot just sell vehicles it has to stand behind what they sell which in my case they have not. Due to GM lack of concern, recalls, reimbursements, lives have been and continue to be at risk

THE VEHICLE'S CLIMATE CONTROL SYSTEM DOES NOT FUNCTION PROPERLY. THE AIR IS NOT PROPERLY DISTRIBUTED OUT OF THE AVAILABLE VENTS. AT TIMES, AIR IS ONLY DISTRIBUTED THROUGH THE FLOORBOARD VENTS. OTHER TIMES IT WILL ONLY BE DISTRIBUTED VIA THE DEFROSTER VENTS. RECENTLY, THE CAR WINDOWS BECAME COMPLETELY FOGGED UP WHILE DRIVING ON THE INTERSTATE AT NIGHT. I ATTEMPTED TO USE THE DEFROSTER, BUT ALL AIR WAS DISTRIBUTED TO THE FLOORBOARD, WHICH HAD NO IMPACT ON THE WINDSHIELD. I HAD ZERO VISIBILITY AND HAD TO PULL OFF ON THE SIDE OF THE ROAD. UP UNTIL THIS INCIDENT, THE PROBLEM HAD BEEN RESTRICTED TO A LACK OF COMFORT, BUT IT HAS NOW BECOME A SAFETY RISK. GMC HAS BEEN PREVIOUSLY MADE AWARE OF THE PROBLEM AND I WAS INFORMED GMC ENGINEERS WERE AWARE OF THE PROBLEM BUT DID NOT HAVE A WAY TO FIX IT.

Roughly every 8 months Sirius XM "radio" runs an automatically triggered free subscription period that includes "weather alerts". These alerts BLOCK part of the car's normal navigational (map) system, requiring UNNECESSARY MOVEMENTS to dismiss the prompts so one can see map details. These movements RISK DRIVING MISTAKES. The weather alerts are unhelpful and unwanted: trivial events that don't affect me. And they keep repeating the same alert multiple times per day. I once called Sirius tech support to have them shut that feature off, but they claimed they couldn't, and to just wait out the promotion period. Sirius XM comes with the car and I can't remove it. I suspect the prompts are a marketing gimmick to trick people into sampling their music channels when they fiddle in the Sirius menus trying to turn off the alerts. Others on social media have reported similar problems in different car models. (PS: I bought the car used in 2019.)

I AM THE OWNER OF A 2017 GMC TERRAIN. YESTERDAY, I WAS INVOLVED IN A CAR ACCIDENT IN THIS VEHICLE. SOME PERSON PULLED OUT IN FRONT OF ME AND I SLAMMED ON MY BRAKES TO AVOID A CAR ACCIDENT. HIS VEHICLE CONTINUED THROUGH AN INTERSECTION IN WHICH HE DID NOT HAVE THE RIGHT AWAY CAUSING ME TO HIT THE FRONT END OF HIS TRUCK. AS THE DRIVER STATES HE DID NOT SEE ME, I CAN CONFIRM I SLAMMED ON MY BRAKES, WHICH ACTED AS THEY COULDN'T STOP. IT FELT AS THE BRAKES WERE NONEXISTENT. THIS WAS AN EXTREMELY TERRIFYING MOMENT, AS I WAS GOING 45MPH (PER THE SPEED LIMIT). AS I HAD READ EARLIER, THE 2018 TERRAINS ALSO SEEM TO HAVE THE SAME PROBLEM.

On Friday, January 19, 2024, I was driving home from school at night in my 2017 GMC Terrain when suddenly my car was chugging and quit. my steering and brakes froze. Other cars were passing me and it was snowing. I was scared someone was going to hit me. I was able to start it up again and to get it to a Walmart parking lot just down the road, but before, it would chug and quit again. My steering was hard. There was no warning light or service light on dashboard telling me something was wrong. I called my sister to come get me. The car would start, but would keep quitting. I called a tow truck and had it towed to the condo. The next day, I went out to start it and it would start and oil light came on. It smelled. I turned it off. I called another tow truck and had it towed to a Mechanic at a shop. He informed me on Monday that the engine was no good due to lack of oil. Even though he said there was 15% left on the gauge. He said these cars have had problems of using excessive oil and he has had to replace and fix them. He also said others had same issue and no warning light as well. I have to replace my engine. He said the cost would be between $5000-$6000. I can't afford that going to school. I'm afraid that if someone else has this problem they could get hurt. I am going to contact General Motors about this, but I'm sure they won't help. Any Suggestions?

timing chain issues resulting in a loss of power of the vehicle while driving. The vehicle stalls out and shuts off. Or it will go into power saving mode and slow down to only 20mph. It did this to me one a MAJOR HIGHWAY and I almost was in an accident. Way to many issues with gmc owners and the timing chain on their vehicles

12/26/2022

We have had 4 transmissions since we bought the vehicle. It slows down to almost a stop after it hits 30 mph and makes weird noises all throughout the vehicle. The back right tire sticks to the pavement and jerks when i start to drive. The key ignition has been fixed several times and still sometimes won't turn with the key or come out. Yes Warranty told the repaid service company to fix whatever, and they did but it still after 2 more transmission hasn't fixed the issues. Engine light and not sure what else.

On5/3/2022 we were driving on I65 around Shepherdsville KY. It was pouring down rain and our windshield wipers stopped working and stuck in the up position. We had a semi on each side of us. This made it even more difficult to see due to the rain coming off of their tires and spraying onto our window. We had to slow down to a dangerous low speed on the interstate due to the difficulty seeing. We made it to the shoulder after almost being hit by a semi We had to sit there until the rain stopped. This was extremely dangerous in itself being that it was on an interstate with high speed limits. We had no choice but to stop in the town of Shephardsville and get a hotel room. We are still trying to make our way back home at this time to IN. This has not been expected by anyone at this time. There were no warnings of any kind.

5/4/2022

The latch for the rear hatch/door does not release every time. There have been instances when itmes have been in the cargo area and when the button is pressed, it will not release the latch. This causes someone to have to crawl over the back seat to retrieve the items from the cargo area. This also is causing my son to have to store items, that would normally be in the crgo area, on his back seat. I owned a 2015 terrain and had this same issue. The latch was replaced but still did not operate correctly.
