A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

Recalls on the 2014 GMC Sierra

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2024294 4,699 units in Canada

Electrical

Issue: On certain trucks, the repairs completed by a General Motors dealer during recall N192220470 (Transport Canada recall no. 2019-325) or customer satisfaction program no. N192270330 may not have been completed properly. As a result, a second repair is required. Additionally, certain trucks may not have had the updated parts installed during production. On certain trucks equipped with a power sliding rear window, the rear defroster wiring could overheat and melt. Safety Risk: Wiring that overheats and melts can create the risk of a fire. Corrective Actions: General Motors will notify owners by mail and advise you to take your truck to a dealership to replace the contact cover for the sliding rear window. The dealer will also update the heating, ventilation, and air conditioning (HVAC) software, if necessary. If the rear window or sliding glass assembly are damaged, they will be replaced.

Recall 2021212 249 units in Canada

Seats And Restraints

Issue: On certain vehicles, the flexible steel cable that connects the seat belt to the outboard side of the driver's seat may have been replaced with an incorrect part during a previous repair. Over time, this cable could flex and may eventually break. If this happens, the seat belt could detach in a crash. Note: This recall only affects certain vehicles that had the driver's seat belt pretensioner replaced after a previous recall repair (recall 2016-153 or 2018-233). Safety Risk: A seat belt that detaches in a crash could increase the risk of injury. Corrective Actions: General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to replace the driver's outboard seat belt pretensioner assembly.

Recall 2019533 37,378 units in Canada

Brakes

Issue: On certain vehicles, there may be an error in the electronic-brake control module software. This could cause the driveline-protection system to activate when a wheel-speed sensor fails. If this happens, the brakes could apply and cause the vehicle to pull to one side. Note: This recall only affects vehicles equipped with four-wheel drive, a 5.3-L engine, and a 3.08 ratio rear axle. The problem can only occur when the vehicle is in four-wheel drive or automatic mode, and travelling at a speed between 66 and 97 km/h (41 and 60 mph). A wheel-speed sensor failure will cause the electronic stability control (ESC) and anti-lock braking system (ABS) warning lights to turn on, and a "Service StabiliTrak" message to display. Safety Risk: A vehicle that suddenly pulls to one side could increase the risk of a crash. Corrective Actions: General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to update the electronic-brake control module software. General Motors advises that using two-wheel-drive mode can eliminate the risk until the recall repair is completed.

Recall 2019420 5,327 units in Canada

Other

Issue: This recall is for aftermarket replacement rear window glass produced by Vitro Automotriz. Certain rear window glass may not have been properly tempered. If the window breaks, the glass may separate into large pieces instead of very small ones. Note: This is a voluntary recall that is not being conducted under the requirements of the Motor Vehicle Safety Act. Safety Risk: Glass that breaks in to large pieces could create a risk of injury. Corrective Actions: The company will notify consumers by mail and instruct them to inspect the designation code marked on the rear window glass. Products affected by this recall have the designation “DOT 287” along with the lettering “VMR” (Replacement Market) and a date code that is before July 2019. This information is printed on the bottom corner of the glass. Consumers should contact Vitro's customer service at 1-412-995-6457 or argbacklites@vitro.com to arrange for replacement of the glass.

Recall 2019325 159,474 units in Canada

Electrical

Issue: On certain trucks equipped with a power sliding rear window, the rear defroster circuit could overheat. This could cause melting, smoke or, in rare instances, a fire. Safety Risk: A fire could create a risk of injury. Corrective Actions: The company will notify owners by mail and advise you to take your truck to a dealer to replace the covers for the buss bar and contacts for the rear sliding window. If the rear window or sliding glass assembly are damaged due to a problem with the rear defroster, they will also be replaced.

Recall 2019324 310,121 units in Canada

Brakes

Issue: On certain vehicles, there could be a reduction in power brake assist due to a decrease in output from the vacuum pump. This could cause a hard brake pedal and an increase in brake pedal effort to stop the vehicle. Safety Risk: A sudden increase in brake pedal force could lead to an increase in stopping distance. This could increase the risk of a crash. Corrective Actions: The company will notify owners by mail and instruct them to take their vehicle to a dealer to reprogram the electronic brake control module.

Recall 2017342 152 units in Canada

Airbag

On certain vehicles, the sensing and diagnostic module (SDM), which controls airbag and pretensioner deployment, contains a software defect which may prevent the deployment of frontal airbags and pretensioners in certain circumstances. Failure of frontal airbags and seatbelt pretensioners to deploy in a crash (when warranted) could increase the risk of injury. Correction: Dealers will reflash the SDM with new software. In vehicles with any previous deployment events recorded in the SDM, the dealers will replace the existing SDM with a new SDM containing the latest software.

Recall 2017325 79,369 units in Canada

Steering

Certain vehicles may experience a temporary loss of electric power steering (EPS) assist followed by a sudden return of EPS assist, particularly during low-speed turning manoeuvres due to an electrical/software issue. If EPS assist is lost and suddenly returned, the unexpected change in steering effort could affect vehicle control, which would increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will update the EPS module software. Note: If power steering assist is lost and the vehicle reverts to manual steering, a dash message would be displayed stating there is an EPS problem. Additionally, this issue could also affect radio, stabilitrak, the driver information centre, chime, door-lock, air conditioning, and/or cruise control function.

THE HEADLIGHTS ARE TOO DIM AND ARE UNSAFE. IN MY 50+ YEARS OF DRIVING, I HAVE NEVER EXPERIENCED HEADLIGHTS SO BAD. I LIVE IN A DARK RURAL AREA WITHOUT ANY STREETLIGHTS AND LOTS OF BICYCLISTS AND DEER. I HAVE ALREADY HAD MANY NEAR MISSES ON RURAL ROADS, AND FEAR IT'S ONLY A MATTER OF TIME BEFORE AN ACCIDENT HAPPENS.

THE HEADLIGHT OUTPUT AT NIGHT, PARTICULARLY IN RURAL BACK ROAD AREAS IS LESS THAN ADEQUATE. POOR REALLY. I ORIGINALLY HAD MOISTURE ISSUES IN BOTH HEADLAMP HOUSINGS, HAD BOTH HEADLAMP HOUSINGS REPLACED AND THE LIGHTING SEEMED TO BE BETTER, HOWEVER NOT VERY MUCH. THE HEADLIGHTS SEEM TO HAVE DARK SPOTS IN THEM AND ONLY LIGHT UP CERTAIN PARTS OF THE ROAD IN FRONT OF ME, AND NEVER MUCH TO THE SIDE OF THE ROADWAY. I FEEL THIS IS BY FAR THE WORST LIGHTING OUTPUT OF ANY VEHICLE I HAVE EVER OWNED, AND ACTUALLY FEEL A LITTLE UNSAFE DRIVING AT NIGHT. I MOST DEFINITELY CANNOT TRAVEL AT HIGHER SPEEDS DURING THE NIGHT AS I FEEL LIKE I CANNOT SEE NEARLY GOOD ENOUGH. I HAVE SIMPLY "DEALT" WITH THE ISSUE SINCE BUYING THE TRUCK IN DECEMBER 2013, THINKING THERE WAS NO FIX TO IT AND THE DEALERSHIP SAID THEY HAVE NOT HEARD OF THIS ISSUE BEFORE.

THERE IS ALREADY A TECHNICAL SERVICE BULLETIN ON THIS MATTER HOWEVER I FEEL IT IS SERIOUS ENOUGH TO BE A RECALL. WHILE DRIVING AT NIGHT IN UNLIGHTED AREAS THE BRIGHT LIGHTS LEAVE SERIOUS DARK AREAS ESPECIALLY IF YOU ARE TRAVELLING ON CURVY ROADS. IF YOU ENCOUNTER A PEDESTRIAN OR OTHER OBJECT IN THE ROAD IN THESE AREAS THEY CANNOT BE SEEN UNTIL ITS POSSIBLY TOO LATE. THE MANUFACTURER WILL ONLY DO THE REPAIR IF YOU COMPLAIN ABOUT IT AND ITS STILL UNDER WARRANTY. I BELIEVE THIS SHOULD BE RECALLED AND REPAIRED BEFORE SOMEONE IS HURT OR KILLED.

THE PROJECTOR HEADLIGHTS ON THIS VEHICLE ARE TERRIBLE. THEY ARE DIM AND HAVE A VERY POOR LIGHT PATTERN. (THE BULB PRESUMABLY MEETS FEDERAL STANDARDS, BUT THE PROJECTOR SYSTEM WAS DESIGNED FOR A BRIGHTER BULB). IT IS VERY DIFFICULT TO SEE THE SIDES OF THE ROAD, OR VERY FAR DOWN THE ROAD, ON ROADS WHERE THERE ARE NO STREETLIGHTS. IT IS EVEN WORSE ON A RAINY, DARK ROAD. GM INSTITUTED A TSB (#PIT5374, ATTACHED) IN FEBRUARY 2015 WHICH INVOLVES REPROGRAMMING THE BODY CONTROL MODULE (BCM) TO INCREASE THE VOLTAGE TO THE HEADLIGHT BULBS AND SUBSTITUTING VOSLA HIR 55 WATT BULBS FOR THE ORIGINAL STOCK 55 WATT BULBS. THE RESULTS ARE A MINIMAL IMPROVEMENT. THE NEW 2016 MODELS HAVE THE SAME HEADLIGHT DESIGN BUT HAVE BEEN UPGRADED TO A HID BULB THAT CANNOT JUST BE PLUGGED INTO THE 2014/15 HEADLIGHTS. THE IMPROVED BULB AND WIRING IS EVIDENCE THE TSB DID NOT REALLY IMPROVE THE LIGHTING VERY MUCH. (THE INTERNET IS FULL OF COMPLAINTS ABOUT THE HEADLIGHTS ON THIS VEHICLE; RECOMMEND YOU GOOGLE "GMC SIERRA HEADLIGHTS" AND SEE WHAT YOU GET!). I LIVE IN NORTHERN VIRGINIA AND WOULD BE GLAD TO COME DOWN TO THE NHTSA BUILDING ON A DARK, RAINY NIGHT AND GIVE YOU A RIDE -- THE PROBLEM ISN'T SO BAD IN AREAS WHERE THERE ARE STREETLIGHTS, BUT IT IS TERRIBLE OUT IN THE COUNTRY. BOTTOM LINE, GM SHOULD BE DIRECTED TO ISSUE A RECALL THAT INVOLVES REPLACING THE WIRING HARNESS AND BULB WITH THEIR LATEST DESIGN. THE HEADLIGHTS IN THE 2014/2014 SIERRA ARE HAZARDOUS TO THE PEOPLE IN THE TRUCK AND TO PEDESTRIANS ALONG THE ROAD. THANKS FOR LISTENING TO MY COMPLAINT, AND PLEASE TAKE ACTION FOR SAFETY'S SAKE. (NOTE: THERE IS NO SPECIFIC TIME, MILEAGE, MPH, ETC., THAT THIS WAS NOTED. IT IS CONTINUAL. I HAD THE TSB PERFORMED IN THE SUMMER OF 2015 AND NOTED MINIMAL IMPROVEMENT AT THAT TIME.)

STRUCTURE:BODY

THE FACTORY INSTALLED RUNNING BOARDS ARE UNSAFE. THE TREADS NEED TO BE LARGER, MORE AGGRESSIVE AND ROTATED 90^. AS THEY ARE THEY ARE SIMPLY SKID PADS WHEN WET OR FROZEN. YOU SIMPLY NEED TO TRY AND ENTER OR EXIT THE VEHICLE AND SEE HOW EASILY YOUR FOOT SIDES OFF CAUSING THE PERSON THE FALL. I HAVE TAKEN SEVERAL SLIPS/FALLS. TODAY I HIT THE BACK OF MY HEAD ON THE DOOR JAM. JUST ROTATING THE TREAD NINETY DEGREES WOULD HELP.

I BOUGHT MY 2014 GMC SIERRA BRAND NEW IN DEC 2014 AND HAD IT BACK TO THE DEALER WITHIN 3 WEEKS BECAUSE I WAS SURE THERE WAS A DEFECT WITH THE HEADLIGHTS ! YOU CAN ONLY SEE MAYBE 30 FEET IN FRONT OF YOU AND NOTHING IF YOU MAKE ANY TURN ON A DARK ROAD WITH NO STREETLIGHTS ! THE MECHANIC AT THE DEALERSHIP SAID THERE WAS NO PROBLEM WITH THE LIGHTS AND THEY MEET ALL GENERAL MOTORS SPECIFICATIONS ...I HAVE READ MANY MANY COMPLAINTS FROM OTHER 2014 GMC SIERRA OWNERS WITH THIS SAME COMPLAINT SO I KNOW ITS NOT MY IMAGINATION OR A PROBLEM WITH MY EYESIGHT !! I SURE HOPE THAT GMC DOESN'T WAIT FOR FATALITIES OR A CLASS ACTION LAWSUIT BEFORE ADDRESSING AND CORRECTING THIS PROBLEM , I HAVE BEEN A LOYAL GMC CONSUMER FOR 45 YEARS BUT THIS OBVIOUS PROBLEM WITH THE LIGHTING AND GMC'S REFUSAL TO ACKNOWLEDGE THAT THERE IS A DESIGN DEFECT I CAN SAY THIS IS THE LAST GMC VEHICLE I WILL EVER PURCHASE . DO THE RIGHT THING GENERAL MOTORS ! FIX THE PROBLEM AND SAVE SOME LIVES !

THE FRONT PROJECTOR HEADLAMPS DO NOT PUT OUT ENOUGH LIGHT TO SAFELY DRIVE ON UNLIT ROADS AT HIGHWAY SPEEDS. THERE IS ALSO LITTLE LIGHT PROJECTED TO THE SIDE MAKING TURNS UNLIT. I RECENTLY HAD A NEAR HIT WITH A PEDESTRIAN ON AN UNLIT STREET BECAUSE OF NO SIDE LIGHTING WHEN MAKING A SLOW TURN. THERE ARE NO HIGHER LUMEN REPLACEMENT BULBS AVAILABLE.

2014 GMC SIERRA. CONSUMER WRITES IN REGARDS TO VEHICLE HEADLIGHT PROBLEMS. *SMD THE CONSUMER STATED WHEN HE MADE TURNS, THERE WAS NOT SUFFICIENT LIGHTING. THE DEALER STATED THE HEAD LIGHTS WERE FOUR INCHES TOO HIGH, SO THEY ADJUSTED THEM. UPON DRIVING AT NIGHT, HE FOUND THE LIGHTING TO THE SIDE HAD SLIGHTLY IMPROVED, BUT THE LIGHT WAS SHARPLY CUT OFF ABOUT 45 FEET IN FRONT OF THE TRUCK ON WHEN THE LOW BEAMS WERE ON, WHICH MADE IT UNSAFE TO DRIVE OVER 35 MPH. THE HIGH BEAMS GAVE GOOD LIGHTING AT DISTANCES, BUT BROUGHT FLASHED FROM ONCOMING TRAFFIC. THE SECOND HEAD LIGHT ADJUSTMENT EXTENDED THE LIGHTING OUT ABOUT 20 INCHES FURTHER, BUT LESS LIGHTING TO THE SIDES FOR TURNING. THE HEAD LIGHTS WERE ADJUSTED AGAIN AND THE TECHNICIAN STATED THE LIGHTS WERE AT THE LEVEL FROM THE FACTORY. THE CONSUMER STATED THE HEAD LIGHTS WERE NOT ADEQUATE IN HIS OPINION.

THE VEHICLES HEADLIGHTS ARE DANGEROUSLY INEFFECTIVE. THEY RARELY ILLUMINATE THE DISTANCE BETWEEN 2 TELEPHONE POLES. THE INEFFECTIVENESS OF THE HEADLIGHTS IS AMPLIFIED ON HILLS OR ON ANY TURN. THE DURING THE TRANSITION FROM DECLINE TO INCLINE, YOU SOMETIMES HAVE BARELY A TRUCKS LENGTH OF ILLUMINATION. ANY CORNER ON A DARK ROAD REQUIRES A SEVERE DECREASE IN TRAVEL SPEED TO AVOID OVER DRIVING THE LIGHTS. I HAVE NEVER DRIVEN A VEHICLE THAT MADE ME FEEL MORE APPREHENSIVE TO GET BEHIND THE WHEEL AFTER DARK. I VISITED THE DEALER WHO EXECUTED A TSB THAT INCREASED HEADLIGHT VOLTAGE AND REPLACED THE BULBS. IT MADE A NEGLIGIBLE IMPROVEMENT AND LEFT THE VEHICLE STILL UNSAFE AT NIGHT. I FREQUENTLY TRAVEL ON RURAL ROADS WITH NO STREET LIGHTS. I HAVE ALMOST HIT WILDLIFE TOO MANY TIMES TO COUNT DUE TO THE POOR VISIBILITY CAUSED BY THESE DANGEROUS HEADLIGHTS. TRAVEL OVER 30 MPH ON DARK COUNTRY ROADS WITH A LEGAL SPEED LIMIT OF 50 IS ILL ADVISED DUE TO THE INEFFECTIVENESS OF THE HEADLIGHTS.
