2016 GMC Terrain Owner Complaints

WHILE DRIVING ON A ILLINOIS INTERSTATE HIGHWAY DURING HEAVY RAIN THE WIPERS SUDDENLY STOPPED IN THE EXTENDED POSITIION PARTICALLY BLOCKING MY VIEW OF THE HIGHWAY. I PULLED OVER AND COULD ONLY RETURN THE WIPER BLADES TO THE HOME POSITION AND THEY WOULD NOT WORK AT THIS POINT. TOOK TO MY DEALER AND IT WAS FOUND THAT THE WIPER TRANSMISSION HAD FAILED. GMC HAS ISSUED A RECALL ON EARLIER MODEL YEARS OF THE SAME MAKE AND MODEL VEHICLE. DEALER CONFIRMED THAT THE FAILURE WAS SAME AS BEING REPORTED ON RECALLED VEHICLES. HOWEVER, THE 2016 MODEL YEAR OF THE GMC TERRAIN IS NOT PART OF THE RECALL AT THIS TIME. FROM RESEARCH I HAVE DONE, THE WIPER TRANSMISSION ON MY VEHICLE IS THE SAME DESIGN AS THE VEHICLES INVOLVED IN THE RECALL. ALTHOUGH AN ACCIDENT WAS NOT A PART OF THIS FAILURE, IT COULD HAVE BEEN AS I WAS DRIVING ON A BUSY INTERSTATE HIGHWAY AT THE TIME AND IT WAS RAINING HARD. COPY OF DEALER INVOICE FOR WORK PERFORMED IS ATTACHED WHICH SHOWS THAT THIS WAS A WIPER TRANSMISSION FAILURE. I UNDERSTAND THAT THEIR HAVE BEEN COMPLAINTS OF OTHER FAILURES FOR THE 2016 MODELS AND WANTED TO ADD MY FAILURE TO THE LIST.

FRIDAY, MAY 10, 2019 THE VEHICLE WAS IN MOTION ON A HIGHWAY, TRAVELING THROUGH A MAJOR THUNDERSTORM WHEN THE WINDSHIELD WIPERS STOPPED WORKING. THE VEHICLE NEEDED TO BE TOWED AND THE WINDSHIELD WIPER MOTOR HAD TO BE REPLACED. THE COST RELATED TO THIS DEFECTIVE PART WAS $1156.98. I UNDERSTAND THIS PART IS CURRENTLY UNDER INVESTIGATION BY THE NHTSA AND THAT THERE IS A RECALL FOR THIS PROBLEM IN THIS YEAR AND MODEL VEHICLE IN CANADA. I'M CONTACTING THE NHTSA SO THAT MY VEHICLE MAY BE ADDED TO YOUR DATA CONCERNING THE 2016 TERRAIN AND THE WIPER MOTOR AND HOPE THAT THERE WILL BE A RECALL HERE IN THE UNITED STATES. *BF

2016 GMC TERRAIN WILL SHOW THE CHECK ENGINE, TRACTION CONTROL AND SERVICE STABILITRAK LIGHTS AFTER GAUGES JUMP UP AND DOWN. VEHICLE WILL THEN GO INTO NEUTRAL AND THEN SUDDENLY SLAM INTO 2ND GEAR. THIS OCCURS AT HIGH RATES OF SPEED ON THE INTERSTATE, AS WELL AS, NORMAL ROADS. THE VEHICLE WILL THEN STAY IN 2ND GEAR AND WILL NOT GO INTO ANOTHER GEAR WHEN IT IS PLACED IN MANUAL EITHER. SOMETIMES, AFTER RESTARTING SEVERAL TIMES, IT WILL DRIVE NORMALLY. OTHER TIMES, IT WILL NOT START ONCE IT IS TURNED OFF. I HAVE HAD IT TO THE GARAGE FIVE TIMES IN THE LAST MONTH. THE STARTER WIRE AND STARTER RELAY HAVE BEEN REPLACED, LOOSE GROUND WIRE TIGHTENED, AND THE ECM REPLACED YET THE CAR CONTINUES TO REPEAT THE SAME CYCLE. CAR CURRENTLY HAS 53,300 MILES ON IT.

THE WHOLE INFOTAINMENT SYSTEM, INCLUDING BACKUP CAMERA AND NAVIGATION, IS NOT FUNCTIONING CORRECTLY. ACCORDING TO REPORTS FROM THE GMC DEALERSHIP AND FROM ONLINE BLOGS, THIS IS A WELL KNOWN SYSTEMIC PROBLEM THAT GM IS NOT ADDRESSING. SAFETY ISSUES: 1. THE BACKUP CAMERA DOES NOT WORK CORRECTLY. WHEN I PUT CAR IN REVERSE THE SCREEN STAYS BLACK WITHOUT ANY VIEW OF THE AREA BEHIND THE VEHICLE.. THIS IS DANGEROUS IN ANY VEHICLE, BUT ESPECIALLY IN THE GMC TERRAIN THAT IS FULL OF BLIND SPOTS. 2. THE RADIO COMES ON SPONTANEOUSLY DESPITE BEING TURNED 'OFF'. THE VOLUME DOES NOT RESPOND TO THE VOLUME CONTROL KNOB. THE RADIO DOES NOT TURN OFF AFTER PRESSING THE ON/OFF CONTROL. TRYING TO DEAL WITH THIS RADIO WHILE DRIVING IS EXTREMELY DISTRACTING AND DANGEROUS. THE PROBLEM STARTED ON 10/01/18 AND HAS NOT RESOLVED ON ITS OWN. MY GMC DEALER HAS SEEN A LOT OF SIMILAR PROBLEMS IN THIS VEHICLE MODEL.

CONSTANTLY DIES. TOOK IT TO A SHOP TO SEE WHAT OR WHY. ITS THE INTAKE VALVE TIMING SOLENOID.

I EVEN GET IT TAKEN IN FOR AN OIL CHANGE BEFORE MY CAR TELLS ME I NEED TOO.

THE DIGITAL CLOCK DOES NOT KEEP ACCURATE TIME, EVEN WHEN IT IS RESET. EVERY TIME THE VEHICLE IS STARTED THE CLOCK IS SEVERAL HOURS OFF. THE DEALER THAT SOLD US THE VEHICLE CLAIMS THIS IS DUE TO THE FACT WE DO NOT HAVE AN ONSTAR SUBSCRIPTION.

STEERING WILL NOT RETURN TO CENTER UNDER HARD ACCELERATION. TESTED CHEVEY EQUINOX WITH V-6 AND HYDRAULIC STEERING SYSTEM PRODUCED THE SAME RESULTS. THIS IS A SEVERE SAFETY PROBLEM WHEN INEXPERIENCED DRIVER OPERATES VEHICLE AS THE VEHICLE CONTINUES IN THE DIRECTION OF THE TURN. THESE VEHICLES ARE VERY QUICK ADD CAN CAUSE SEVERE DAMAGE TO VEHICLES/PEDESTRIANS IF NOT AWARE OF THIS PROBLEM. AT PRESENT DEALER HAS NOT REPAIRED/SOLVED PROBLEM AND STATED IT IS NOT THAT SEVERE.OF A PROBLEM

4/3/2018

WHILE I WAS DRIVING THE CAR STEERING WHEEL WOULD LOCK MULTIPLE TIMES. WHEN DRIVING MY CAR STOPPED AT THE MIDDLE OF AN INTERSECTION WHEN DRIVING MY CAR WOULD SWITCH ON AMD OFF THE ECO MODE AND I FELT A JOLT EVERY TIME

1/29/2020

I HAD A TEMPORARY BRAKE FAILURE AT 25MPH WITH A HARD BRAKE. I HAD A CAR PULL OUT IN FRONT OF ME AND I HAD TO HARD BRAKE. THE BRAKE PEDAL WAS SOFT AND WENT ALL THE WAY TO THE FLOOR WITH NO BRAKING UNTIL IT WAS ALL THE WAY TO THE FLOOR AND IT FINALLY WORKED WITH A SUDDEN STOP/JOLT. WHEN THIS HAPPENED IT MADE A LOW SORT OF ALMOST VIBRATION SOUND. I DID NOT FEEL A VIBRATION IN THE BRAKE PEDAL THOUGH. THE BRAKES WORKED WELL BEFORE THAT AND AFTER THAT. IF THE BRAKE WOULD HAVE NOT SUDDENLY GRABBED WHEN THE PEDAL WAS TO THE FLOOR I WOULD HAVE HIT THE CAR. I WAS GOING ABOUT 25MPH. I KNOW WHAT IT SOUNDS AND FEELS LIKE TO HAVE WORN BRAKES AND ROTORS. THIS WAS NOT IT. AGAIN IT WAS A TEMPORARY FAILURE AND AFTER THAT THE BRAKES ARE THEIR NORMAL FIRMNESS AND RESPONSIVENESS. THIS IS DEFINITELY A SAFETY HAZARD AS IT VERY UNPREDICTABLE.

4/15/2019

WHEN BRAKES ARE APPLIED THE VEHICLE TAKES EXTREMELY LONG TIME TO PROPERLY STOP. BRAKES FEEL SOFT AND FADE WHEN APPLIED AND I HAVE NEARLY STRUCK VEHICLES FROM THE REAR SEVERAL TIMES WHEN ATTEMPTING TO STOP. I TOOK THE VEHICLE TO AN INDEPENDENT MECHANIC BUT, NO OBVIOUS DEFECT WERE FOUND BY THE MECHANIC. I FEAR THAT THE BRAKES ARE NOT PROPERLY FUNCTIONING IN THIS VEHICLE AND IT IS A FACTORY DEFECT.

THE TIRES ON THE CAR LOSE AIR PRESSURE VERY QUICKLY, EVEN WHEN THE CORRECT AMOUNT OF AIR PRESSURE IS ADDED. THE CAR CAN SET IN THE GARAGE FOR A FEW DAYS AND ONE TIRE MAY HAVE LOW AIR PRESSURE AND I FILL IT UP TO 32 PSI. A WEEK OR LESS LATER, ANOTHER TIRE WILL HAVE LOW AIR PRESSURE AND SO ON. THIS IS HAS NEVER HAPPENED BEFORE WITH OTHER GM SUV'S I'VE OWNED.

I HAVE HAD A RECURRING ISSUE WITH MY ACCELERATOR ASSEMBLY ON MY 2016 GMC TERRAIN DENALI. THE GM PART NUMBER IS 84022579. THE INITIAL PEDAL ASSEMBLY BROKE AT 26,722 MILES, WHEN THE CAR WAS ONLY 18 MONTHS OLD. THE PART WAS REPLACED, UNDER WARRANTY, AT A CERTIFIED GM DEALER. THE ISSUE HAPPENED AGAIN ANOTHER 18 MONTHS LATER. UNFORTUNATELY GM ONLY CERTIFIES THE PART FOR 12 MONTHS AND 12,000 MILES, SO I HAD TO PAY FOR THE SECOND PEDAL ASSEMBLY OUT OF POCKET. THE SECOND REPAIR WAS ALSO DONE AT A CERTIFIED GMC DEALERSHIP. THIS RECURRING HISTORY OF ISSUES IS A CLEAR INDICATION THAT GM IS USING A FAULTY PART IN THIS VEHICLE,WHICH CREATES A SIGNIFICANT SAFETY ISSUE FOR DRIVERS. WHEN THE PEDAL ASSEMBLY BREAKS DOWN, IT AUTOMATICALLY PUTS THE CAR INTO LOW ENGINE POWER MODE. IF YOU ARE DRIVING ON A FREEWAY, YOUR SPEED WILL SUDDENLY DROP FROM 70 MPH TO 25 MPH IN A MATTER OF SECONDS. FURTHER, THERE IS ESSENTIALLY NO ABILITY TO ACCELERATE WHEN THE CAR IS IN LOW POWER MODE. THE OTHER SIGNIFICANT SAFETY ISSUE IS THAT EVENTUALLY THE CAR WILL GO BACK TO NORMAL AFTER A FEW MORE DAYS/USES. THE ENGINE LIGHT WILL GO OFF AND GIVE YOU THE IMPRESSION THAT THE ISSUE NO LONGER EXISTS, OR WAS A FALSE ALARM. THEN IT WILL HAPPEN AGAIN WITHOUT WARNING. I HAVE HAD THIS ISSUE HAPPEN TO ME ON 7 DIFFERENT OCCASSIONS, IN A VARIETY OF DRIVING CONDITIONS (HIGHWAY, CITY, FREEWAY, ETC). I'VE SPENT THE PAST 5 WEEKS WORKING WITH GMC CUSTOMER SERVICE TRYING TO GET A RESOLUTION. THEY HAVE INDICATED THAT THEY DO NOT THINK THIS IS A FAULTY PART, AND HAVE NOT PROVIDED ANY ASSISTANCE. THEY ARE IGNORING THE FACTS AND HISTORY OF MY CASES, INCLUDING MULTIPLE GMC CERTIFIED DIAGNOSES CONFIRMING THAT THE SAME PART CONTINUES TO BREAK. I WOULD ENCOURAGE NHTSA TO INVESTIGATE THIS MATTER AND HOLD GM ACCOUNTABLE FOR THIS. IT CREATES SIGNIFICANT SAFETY RISKS FOR DRIVERS, AND IMPOSES SIGNIFICANT COSTS ON DRIVERS.

VEHICLE SINCE PURCHASE SHOWS NO SIGNS OF LEAK BUT GOES THROUGH OIL AT ABOUT 1 QUART EVERY 1000 MILES MAX. CHECK ENGINE LIGHT ALWAYS ON, SENSORS INDICATE POSSIBLE FAULTY PISTON RINGS. ALL WERE PROBLEMS IN LATER MODEL GMC TERRAINS. WHEN LOW ON OIL WHILE DRIVING AND STATIONARY ALL LIGHTS WILL LIGHT UP AND ENGINE WILL GO INTO REDUCED POWER MODE SAYING TO SERVICE STABILITRACK. CAR WILL NOT GO ABOVE 10 MPH WHEN IN THIS MODE, SOMETIMES UNABLE TO MOVE AT ALL. GOES AWAY AFTER MORE OIL ADDED. GMC TERRAIN HAD RECALLS ON YEARS 2010-2013 FOR ALL ENGINE FAILURE PROBLEMS/REPAIRS DUE TO FAULTY PISTON RINGS/OIL CONSUMPTION ISSUES. NUMEROUS 2014-2016 GMC TERRAINS HAVE CLAIMS OF THE REDUCED POWER/STABILITRACK PROBLEM WITH NO SOLUTION, I BELIEVE BOTH PROBLEMS ARE DIRECTLY RELATED.

Multiple brake lines have corroded out of the gas tank. This caused gas to slowly leak from the vehicle . Not available for inspection - currently being fixed. Dealer confirmed multiple lines corroding. It has been inspected by a certified dealer, Golling in Chelsea, Michigan. There was no warning. Initially smelled gas, but could not pinpoint where it was coming from. Eventually the leak became so large that gas usage was excessive and smell was very strong.

I HAVE BEEN DRIVING MY VEHICLE WHEN ON THREE SEPERATE OCCASIONS THE SERVICE STABILITRAK MESSAGE FLASHED ON THE DIC AND I LOST ENGINE POWER.

I TRIED TAKING IT TO THE DEALERSHIP TWICE AND WAS TOLD THEY CANT REPLICATE THE PROBLEM SO NOW I DONT EVEN BOTHER TRYING TO HAVE THEM FIX IT. HOW CAN A MAJOR SAFETY ISSUE LIKE THIS NOT BE FIXED BY GM!!

The engine - My engine blew because oil evaporated out of the #1 cyclinder, which drained the oil. No warning lights went on and the vehicle stalled in the middle of rush hour traffic. The dealership told me it was because of a factory defect, but no recall on that part of the vehicle. This could have been much worse if the vehicles behind me were going faster than they were and not able to stop before rear ending me. Because this was a factory defect it should have been recalled and I should have been notified of this problem when I bought the vehicle.

I was driving my morning commute to work, when I came upon a stop light. I was pressing the brakes and the brakes failed to engage which caused me to hit a car in front of me. I did not have any warnings that the brakes were defective. The warning on the dash did not indicate that there was anything wrong with brakes. I had my set belt, was going the speed limit and my brakes just gave out. I have injury’s to my arms, shoulder, neck, and head. The other vehicle driver was not hurt. Thank the Lord.
