• Duramax LML fuel pump (CP4) failure

  Best left to a shop

  Signs: Sudden stalling or no-start, low fuel pressure codes such as P0087.

  Fix: Prevention: change the fuel filter on schedule and buy fuel from busy stations. Some owners replace the CP4 with a different pump design as prevention. A failed pump usually means a full fuel system replacement at a diesel shop.

• DEF heater and NOx sensor problems

  Moderate DIY

  Signs: 'Poor DEF quality' or reduced power messages, check engine light.

  Fix: Scan for codes. Common fixes are a NOx sensor or the DEF heater and tank assembly.

• Worn idler arm and pitman arm

  Moderate DIY

  Signs: Loose, wandering steering, clunks, play in the steering wheel.

  Fix: GM will notify owners, and dealers will replace the front passenger air bag inflator with an alternate one, free of charge. Interim letters notifying owners of the safety risk were mailed on February 25, 2021. Second notification letters will be mailed once the remedy is available. Owner notification letters were mailed to 40 VIN owners on May 11, 2021. A second owner notification letter was mailed to all other owners on January 24, 2022.

  General Motors LLC (GM) is recalling certain 2009-2014 Chevrolet Silverado HD and GMC Sierra HD, 2009 GMC Topkick 5000, 6000, 7000 and 8000 Series and Isuzu F Series, and 2009-2018 Chevrolet Express, and GMC Savana vehicles, equipped with certain Plastic-Handle Fire Extinguishers or Push Button 'Pindicator' Fire Extinguishers. These extinguishers may become clogged, preventing the extinguisher from discharging as expected or requiring excessive force to activate the extinguisher. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable. For a full list of the affected fire extinguisher models visit: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17E062-5427.pdf

  Risk and fix

  Risk: In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury.

• Fuel System, Gasoline:Storage:Auxillary Tank

  Oct 2017 · #17V664000

  General Motors LLC (GM) is recalling certain 2011-2015 Chevrolet Silverado 3500 and GMC Sierra 3500 trucks equipped with dual fuel tanks. The low fuel level sensor for the front tank may stick causing the rear tank to overfill the front tank.

  Risk and fix

  Risk: If the front tank overfills, the excess pressure may cause the front tank to expand and contact the driveshaft, possibly resulting in a hole in the tank. The hole will leak fuel, which in the presence of an ignition source, can increase the risk of a fire.

  Fix: GM has notified owners, and dealers will replace the rear tank fuel pump or update the fuel-level sensor software, as well as inspect the front tank, replacing it as necessary, free of charge. The recall began December 11, 2017. Owners may contact GM customer service for Chevrolet 1-800-222-1020 or for GMC customer service at 1-800-462-8782. GM's number for this recall is 17399.

    THE VEHICLE LIGHTS ARE VERY DIM EVEN WITH THE HIGH BEAMS ON. WHILE DRIVING AT NIGHT CAN BARELY SEE IN FRONT OF ME. THESE ARE A HAZARD TO ME AND OTHERS, SINCE NOT BEING ABLE TO SEE A GOOD DISTANCE IN FRONT OF THE VEHICLE MAKES HARD TO SEE PEDESTRIANS, ANIMALS OR DEBRIS IN THE ROAD AT NIGHT.

    CAN NOT SEE THE ROAD WITH THE LIGHT OUTPUT WITH THESE FACTORY HEADLIGHT

  • Filed Mar 2016

    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.

  • Filed Feb 2016

    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.

    Transmission Control Module TCM failed while driving down the freeway I84 in Boise Idaho. AC Delco part number 24256861. This caused the truck to go into limp mode when at highway speed. While in limp mode the truck would not respond to throttle commands. Truck slowed to 20mph causing a disruption in traffic flow and making it very difficult to get off the freeway, dodging traffic. The TCM failure has been confirmed through a local GMC dealer (Dennis Dillon in Boise Idaho). The Manufacture (General Motors) has discontinued manufacturing this part leaving my vehicle and thousands of others failed. GM's responce is the part is on a national backorder. 24-26 months at the earliest. Aftermarket support is none existent. There were no warning lamps or messages or symptoms prior to the failure. Very limited parts are available on Ebay (10 or less) . Dealer price for the TCM is $710. Ebay pricing is 4-10 thousand. GM customer assistance provides no answers and fails to ackowledge the safety concern of the failed transmission controller.

    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.

    THE HEADLIGHTS ON THIS TRUCK PROVIDE INADEQUATE LIGHTING, INCLUDING BOTH LOW BEAMS AND HIGH BEAMS. ANY NIGHT DRIVING IS DIFFICULT DUE TO LIMITED VISIBILITY, THERE SIMPLY IS NOT ENOUGH ILLUMINATION TO SEE. CAN BE VERY DANGEROUS - ESPECIALLY AT SPEEDS ABOVE 35 MPH OR DURING PRECIPITATION. THE HEADLIGHT HAS A SEVERE DESIGN FLAW WITH GMS SAYS IS A SHUTTER SYSTEM. THIS TYPE OF DESIGN DOES NOT LEAVE ANY OPTIONS FOR SIMPLY CHANGING THE TYPE OF BULB - THE DESIGN IS ACTUALLY AT FAULT FOR THE POOR VISIBILITY. THE VISIBILITY PROBLEMS SIMPLY CANNOT BE FIXED WITH A DIFFERENT BULB TYPE DUE TO THE SHUTTER DESIGN TYPE. THE NEED FROM A NEW HEADLIGHT WILL SOLVE THE PROBLEM. MANY COMPLAINTS ARE BEING REGISTERED ONLINE RELATED TO THE VISIBILITY PROBLEM. THESE TRUCKS ARE NOT SAFE TO DRIVE AT NIGHT. IF THERE IS A STANDARD FOR MINIMUM HEADLIGHT ILLUMINATION FOR NIGHT TIME DRIVING, THIS MODEL HEADLIGHT NEEDS TO BE REVIEWED IF IT IS MEETING THE MINIMUM STANDARD. NOT SAFE, A DEFINITE PROBLEM THAT NEEDS ATTENTION.

    The contact owns a 2014 GMC Sierra. The contact stated that while driving at 42 MPH, she was involved in a three-vehicle accident after a vehicle involved in another accident ricocheted and hit her vehicle. The driver's side air bag exploded but did not deploy. Black smoke was released from the steering wheel and the air bag fell on the contact's left leg. The driver seat belt retractor fell apart during the accident which sliced the top part of the contact's ear; in addition, the failure sent a part of the contact's earing into her ear canal. The driver of the vehicle that was originally hit in the accident died the next day in the hospital; another passenger in that same vehicle was critically injured.

    WHILE SITTING PARKED IN MY DRIVEWAY WITH THE CAR IN PARK AND THE ENGINE IDLING, THE SIDE CURTAIN AIRBAGS ON MY 2014 GMC SIERRA DEPLOYED FOR NO IDENTIFIABLE REASON. GM HAS PROVIDED PART OF THE CRASH DETECTION REPORT DATA TO ME. THE VEHICLE EVENT SEVERITY STATUS: ROLLOVER INDICATES "YES". THE CDR ALSO SHOWS THAT THE VEHICLE'S SPEED WAS ZERO AND THE ENGINE WAS AT IDLE (512 RPM). AS NOTED, THE VEHICLE WAS PARKED ON A LEVEL SURFACE AND THERE WAS NO MOVEMENT OF THE VEHICLE OTHER THAN ANY MOVEMENT OF THE PASSENGERS IN THE VEHICLE. THE VEHICLE DID NOT ROLL AS IS EVIDENCED BY THE FACT THAT THERE IS NO EXTERNAL DAMAGE.

    REGARDING 2014 GMC SIERRA 6 CYLINDER FULL SIZE PICKUP. VEHICLE VIBRATES AS IF RUNNING OVER RUMBLE STRIPS AT APX 1500 RPM. LOCAL GM SERVICE CENTER AND GM CORPORATE REPRESENTATIVE STATED ABOVE IS NORMAL VEHICLE OPERATION. LOCAL GM SERVICE CENTER CORRECTLY SUGGESTED THAT TRUCK BE DRIVEN FASTER OR SLOWER TO PREVENT VIBRATION OR THAT VEHICLE BE DRIVEN IN 5TH GEAR RATHER THAN OVERDRIVE 6TH GEAR TO PREVENT VIBRATION. IF VEHICLE IS NOR DRIVEN FASTER OR SLOWER TO GET OUT OF VIBRATION RANGE, THE TRUCK WILL VIBRATE ENDLESSLY. 2014 GMC SIERRA IS AN UNSAFE VEHICLE. NEEDING TO SPEED UP OR SLOW DOWN TO PREVENT VIBRATION SIGNIFICANTLY INCREASES RISK FOR MVA. NEEDING TO DRIVE IN 5TH GEAR RATHER THAN 6TH GEAR REDUCES GAS MILEAGE AS REPORTED TO NHSTA. LOCAL MECHANICS HAVE COMMENTED THAT THE ABOVE VIBRATION COMPLAINT IS COMMON TO 2014 6 CYLINDER GMC/CHEVY FULL SIZE PICKUP TRUCKS AND THAT THE VIBRATION MAY BE SECONDARY TO CYLINDER DEACTIVATION AND CHASSIS RIGIDITY. IT CERTAINLY WOUND BE A SHAME FOR A COLLISION TO OCCUR OR FOR A PEDESTRIAN TO GET RUN OVER BY A DRIVER OF A 2014 GMC/CHEVY FULL SIZE PICKUP WHO HAD TO SPEED UP OR SLOW DOWN TO REDUCE EXCESSIVE VIBRATION AT APX 1500 RPM

WHEN TOOK DELIVERY OF THE TRUCK AND DROVE IT HOME THE VIBRATION WAS BETTER AT A SLOWER SPEED BUT INCREASED AS THE SPEED INCREASED. WE RETURNED THE TRUCK TO THE DEALERSHIP AND THEY CHECKED IT OUT AND SAID THAT THEY BALANCED THE TIRES AND ROTATED THE DRIVESHAFT 180 DEGREES. IT SEEM TO BE A LITTLE BETTER. BECAUSE WE TAKE THIS TRUCK TO FLORIDA FOR THE WINTER AND IT IS LOADED MY HUSBAND DECIDED THAT HE WOULD PUT SOME WEIGHT IN THE BACK OF IT TO SEE HOW IT WOULD AFFECT IT. THE VIBRATION WAS BETTER AT A SLOWER SPEED AND WORSE AT A HIGH SPEED ON THE HIGHWAY. THE TRUCK HAS NOW BEEN BACK AT THE DEALERSHIP FOR A WEEK AND WE HAVE NOT HEARD ANYTHING IN REGARDS TO IT.

    I PURCHASE THIS VEHICLE NOV. 2013, AND EVER SINCE I NOTICE THAT THE HEADLIGHT ON THIS VEHICLE DO NOT LIGHT THE ROAD PROPERLY, WHETHER YOU HAVE THEM IN LOW OR HIGH BEAM. THE DISTANCE OF THE LOW AND HIGH BEAM APPEAR TO BE THE SAME (AT TIMES IT SEEMS THE HIGHS) ARE AIMING SKYWARD. NOT TO LONG AGO I ALMOST RAN OVER A WOMAN AND A CHILD WHO WERE CROSSING A STREET OVER TO MY LEFT WHEN I WAS ATTEMPTING TO MAKE A LEFT TURN (THIS WAS A DARK AREA). LUCKILY I WAS GOING SLOW WHEN I WAS MAKING THE TURN AND WAS ABLE TO SEE THEM WHEN THE HEADLIGHTS HIT THEM AND CAME INTO VIEW. BY THIS STATEMENT I AM TRYING TO POINT OUT THAT THERE NO LIGHTING TO EITHER SIDE OF THE VEHICLE, I AM SURE (POSITIVE) THAT IF I WOULD HAVE BEEN MAKING A RIGHT TURN AN ACCIDENT WOULD HAVE HAPPEN. ARE THERE ANY RECALLS REGARDING THIS PROBLEM? IF NOT, I THINK THERE SHOULD ONE. BECAUSE IF SOMETHING LIKE THIS EXAMPLE I AM SUBMITTING TO YOU EVER HAPPENS, THE DRIVER WILL HELD RESPONSIBLE.

    THE HEADLIGHTS ON THIS TRUCK PROVIDE INADEQUATE LIGHTING, INCLUDING BOTH LOW BEAMS AND HIGH BEAMS. ANY NIGHT DRIVING IS DIFFICULT DUE TO LIMITED VISIBILITY, THERE SIMPLY IS NOT ENOUGH ILLUMINATION TO SEE. CAN BE VERY DANGEROUS - ESPECIALLY AT SPEEDS ABOVE 35 MPH OR DURING PRECIPITATION. THE HEADLIGHT HAS A SEVERE DESIGN FLAW WITH GMS APPROACH AT A SHUTTER SYSTEM. THIS TYPE OF DESIGN DOES NOT LEAVE ANY OPTIONS FOR SIMPLY CHANGING THE TYPE OF BULB - THE DESIGN IS ACTUALLY AT FAULT FOR THE POOR VISIBILITY. THE VISIBILITY PROBLEMS SIMPLY CANNOT BE FIXED WITH A DIFFERENT BULB TYPE DUE TO THE SHUTTER DESIGN TYPE. MANY COMPLAINTS ARE BEING REGISTERED ONLINE RELATED TO THE VISIBILITY PROBLEM. THESE TRUCKS ARE NOT SAFE TO DRIVE AT NIGHT. IF THERE IS A STANDARD FOR MINIMUM HEADLIGHT ILLUMINATION FOR NIGHT TIME DRIVING, THIS MODEL HEADLIGHT NEEDS TO BE REVIEWED IF IT IS MEETING THE MINIMUM STANDARD. NOT SAFE, A DEFINITE PROBLEM THAT NEEDS ATTENTION. *TR

    THE HEADLIGHT PERFORMANCE ON THIS TRUCK IS THE WORST I'VE SEEN IN ANY VEHICLE, BUT FOR A TRUCK, I CANNOT BELIEVE THEY ARE ALLOWED ON THE ROAD AT NIGHT. THE OWNER'S MANUAL STATES THEY ARE FACTORY SET AND DO NOT NEED ADJUSTMENT. THAT INFORMATION WAS OBVIOUSLY NOT CHECKED DURING THE QUALITY CHECK OR CHECKED BUT FELT IT WAS AS GOOD AS IT GETS. ON HIGH BEAM, THE DRIVER'S SIDE LIGHT IS POINTING SO FAR UP, IT'S IN THE TREES AND ABOVE THE ROAD. THE RIGHT SIDE HIGH AND LOW BEAMS ARE INADEQUATE FOR ALL PURPOSES, ESPECIALLY SEEING AROUND CURVES AND TURNS. YOU ARE LITERALLY BLIND ON A DARK STREET, EVEN WITH THE FOG LIGHTS. VERY POOR ILLUMINATION OF THE ROAD. I'VE TAKEN IT IN TO THE DEALER FOR ADJUSTMENT AND THEY DID NOT CHANGE ANYTHING. THIS WILL BE THE LAST GM PRODUCT I BUY SINCE IT SEEMS THE LAST THREE VEHICLES I'VE OWNED HAD ISSUES THAT COULD NOT BE RESOLVED. AND I AM A MEMBER OF THE GM FAMILY. FOR THE PRICE OF THESE VEHICLES, THEY SHOULD BE TOP QUALITY. GM SHOULD BE ASHAMED OF THE QUALITY THEY DELIVER TO CUSTOMERS FOR VEHICLES PRICED OVER $45K. *TR

I'VE BEEN DRIVING CARS WITH PROJECTOR HEADLIGHTS FOR YEARS, SO I KNOW THAT IS NOT THE REAL ISSUE. THESE LIGHTS ARE JUST POORLY DESIGNED OR CHEAP. TRIPS TO THE DEALER ARE UNFRUITFUL. THE DEALER KNOWS THEY ARE POOR, BUT CAN DO NOTHING EXCEPT BE SURE EVERYTHING IS PROPERLY ADJUSTED. IF YOU ARE LOOKING AT BUYING A 2014 GMC PICKUP, BUY SOMETHING ELSE. THEY ARE THAT BAD.

    THE FACTORY SUPPLIED RUNNING BOARDS HAVE TREADS THAT FAIL TO PROVIDE ANY TRACTION FOR FEET WHILE ENTERING OR EXITING. THE TREADS NEED TO BE ROTATED 90 DEGREES AND MADE OF A SOFTER RUBBER WITH A DEEPER AND MORE AGGRESSIVE TREAD PATTERN. AS THEY EXIST THEY ARE VERY SLIPPERY ESPECIALLY WHEN WET OR FROZEN. GIVEN THE ADDED HEIGHT OF TRUCKS IT REQUIRES SOME USE OF THE RUNNING BOARDS TO ENTER/EXIT THE TRUCK. ESPECIALLY WHEN YOU ARE 68.

The driver seat belt retractor fell apart during the accident which sliced the top part of the contact's ear; in addition, the failure sent a part of the contact's earing into her ear canal. The driver of the vehicle that was originally hit in the accident died the next day in the hospital; another passenger in that same vehicle was critically injured.

NHTSA 5-Star Safety Ratings from government crash tests. Ratings can differ by cab style and 2WD/4WD.

NHTSA hasn't published star ratings for this truck. Many heavy-duty pickups aren't included in NHTSA's crash-test program, so this doesn't mean the truck is unsafe.
