• 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: Replace the idler arm and pitman arm, and check tie rods. Many owners add an idler arm support brace. Get an alignment afterward.

• Cracked dashboard

  Easy DIY

  Signs: Cracks across the dash top, especially near the passenger airbag.

  Fix: Cover it with a molded dash cover or replace the dash pad. Make sure a cover doesn't block the airbag.

  Apr 2018 · #18V267000

  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

• 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.

Owners may unknowingly draw too much current through the vehicle's trailer harness resulting in the melting of fusible link for the auxiliary battery.

  Risk and fix

  Risk: If the fusible link melts it may come into contact with adjacent components, damage the electrical center cover, the nearby wiring harness conduit and other vehicle components, increasing the risk of a fire.

  Fix: GM will notify owners and dealers will replace the jumper harness with one that includes a 40 amp inline fuse, and provide the owner with supplemental Owner Manual information, free of charge. The recall began on August 29, 2014. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is 14260.

IT WORKED PROPERLY THEN. THIS HAS HAPPENED 4 OTHER TIMES. THE LATEST INCIDENT HAPPENED YESTERDAY, WITH OUT USING CRUISE CONTROL. TRAVELING AT 30 MPH IT SHUT ME DOWN AGAIN . ONE OF THE SCARIEST TIMES , I WAS TRAVELING IN 5 LANES OF TRAFFIC AND IT SHUT ME DOWN TO HALF POWER AND IT WAS QUITE DANGEROUS FOR US TO TRY AND MERGE OUT OF THE WAY AND GET OFF TO A SAFE SPOT ON SIDE OF INTERSTATE. I CALLED THE DEALER AND THEY TOLD ME THERE HAS NOT BEEN A RECALL ON THIS ISSUE, BUT IT SEEMS VERY MUCH LIKE A SAFETY ISSUE WITH ME. THE DEALER ALSO TOLD ME AS WELL AS OTHER AUTO SPECIALIST IS THAT THIS IS A COMMON PROBLEM WITH THIS MODEL OF VEHICLE AND THAT IT WILL COST ABOUT 700 DOLLARS TO REPLACE THE THROTTLE CABLE ASSEMBLY. *TR

    FIRST OFF WOULD BE MY DASHBOARD AIR BAG, THE DASHBOARD PLASTIC IS CRACKING WITH THE CONCERN ON FLYING DEBRIS I BROUGHT MY GMC 1500 INTO MY LOCAL SERVICE/SALES CENTER AND HE TOLD ME WITH OUT A RECALL THERE IS NOTHING HE COULD DO FOR ME. SECOND I HAVE BEEN DEALING WITH WHAT SEEMS TO EITHER THE POWER TRAIN OR BRAKES FROM DAY ONE I PURCHASED MY TRUCK. WHAT IT DOES IS WHEN I COME TO A COMPLETE STOP, RELEASE THE BRAKE, AND THEN APPLY THE ACCELERATOR I GET A BIG CUR PLUNK SOUND AND FEELING OF THE TRUCK JERK. THIS IS COMING FOR THE REAR END OF MY TRUCK I WOULD ASSUME THE REAR AXIAL. I HAVE BROUGHT THIS UP TO MY LOCAL SERVICE/SALES CENTER , MULTIPLE TIMES. HE HAS NOT STOPPED THE PROBLEM AND TELLS ME THERE IS NOT MUCH MORE HE CAN DO WITHOUT THE MANUFACTURER POSTING A BULLETIN OUT.

    PURCHASED TRUCK 11/10/2011 WITH 3 MILES ON IT. AT 4,000 MILES THE TRUCKS BRAKES STARTED PULSATING AND SHIMMING WHILE APPLING BRAKES GOING DOWN HILL. TOOK IT TO DEALER , THEY RESURFACED FRONT ROTORS. GOOD TILL 5,700 MILES AND IT STARTED DOING THIS AGAIN, BUT WORSE, ALSO PROBLEMS JUST BRAKING ANY WHERE. TOOK BACK TO DEALER, NOW THEY RESURFACED REAR DRUMS. I'M VERY DISAPPOINTED IN THIS NEW VEHICLE'S BRAKING SYSTEM. THEY WROTE THE BRAKES WERE WARPED DURING BOTH VISITS, AND NO REASON AS TO WHY THIS IS HAPPENING TO MY NEW VEHICLE. *TT

    WHILE DRIVING UP HILL THE TRUCK JUST SHUT OFF. COULD NOT START IT AGAIN. THERE WAS NO WARNING SIGNS IT TOOK OVER 2 WEEKS AND 2 DIFFERENT GM DEALERS TO FIGURE OUT IT WAS A FUEL INJECTOR PUMP THAT EXPLODED. THERE WERE NO CODES ON THE TRUCKS COMPUTER TO ACKNOWLEDGE THERE WAS ANY PROBLEM WITH THE TRUCK EVEN AFTER IT WOULD NOT START. COULD HAVE BEEN EXTREMELY DANGEROUS IF OUR CIRCUMSTANCE WE'RE DIDFERENT. 5 MILES EARLIER AND WE WOULD HAVE BEEN ON AN EXPRESS WAY.

    SEVERE FRAME CORROSION (ALL SECTIONS OF FRAME). THE UNDERCOATING IS FLAKING OFF IN ALL SECTIONS EXPOSING BARE METAL WHICH IS RAPIDLY CORRODING THROUGHOUT THE FRAME. THE TRUCK IS IN MINT CONDITION INSIDE AND OUT OTHER THAN THIS ISSUE. GM STATED THAT "RUST" IS NOT COVERED UNDER MY ACTIVE WARRANTY. THIS IS A FAULTY COATING APPLICATION OR A FAULTY METAL ISSUE. THIS VEHICLE WILL BE UNSAFE SOON AND IT JUST HIT 12,000 MILES. I PURCHASED THIS "GM CERTIFIED PRE-OWNED" TRUCK TWO WEEKS AGO FROM THE GM DEALERSHIP AND JUST REALIZED THAT MANY, MANY COMPLAINTS HAVE BEEN FILED FOR THIS VERY ISSUE. *TR

    WHILE DRIVING A GMC 3500 DENALI HD 4X4 EQUIPPED WITH THE DIESEL ENGINE AND AUTOMATIC TRANSMISSION, WITH LESS THAN 90 MILES ON IT, THE REAR ADJUSTMENT BRACKET FOR THE LEFT SIDE TORSION BAR BROKE AND FELL OFF THE VEHICLE WHILE GOING OVER A SPEED BUMP AT LESS THAN 20MPH. MORE SPECIFICALLY, THE PART MOUNTS NEAR OR IN THE CROSSMEMBER BRACE AND IS USED TO ADJUST THE PRELOAD ON THE TORSION BAR. AFTER THE PART BROKE AND FELL OFF THE VEHICLE HAD A NOTICEABLE LIST TO THE LEFT SIDE. THE PART IS A CAST PART THAT APPEARS TO HAVE FAILED IN OVERLOAD (UNDERDESIGNED) OR DUE TO HIGH STRESS CONCENTRATIONS (POOR FIT/TOLERANCE ISSUES). AT CITY SPEEDS I WOULDN'T EXPECT MUCH MORE THAN WHAT HAPPENED TO ME. HOWEVER, AT HIGHWAY SPEEDS WITH A LOADED TRUCK OR TOWING A TRAILER, THE FAILURE COULD RESULT IN CONTROL ISSUES AND THEREFORE, IN MY OPINION, SHOULD BE CLASSIFIED AS A SAFETY ISSUE. THE DEALER TOOK THE VEHICLE BACK AND HAD A NON-GMC FACILITY "REBUILD" THE FRONT SUSPENSION. ACCORDING TO THE DEALER, GMC HAS HAD AT LEAST ONE OTHER SIMILAR INCIDENT. I CURRENTLY HAVE THE BROKEN PART AND POSSIBLY THE ORIGINAL PART FROM THE RIGHT HAND SIDE OF THE VEHICLE. *LN

    THREE OUT OF FOUR TIRES HAD SEPARATION. THE TIRES ARE GOODYEAR WRANGLERLT265/ 60R20E1. TWO TIRES WERE REPLACED ON 2/21/2014 DUE TO SEPARATION OF LEFT REAR TIRE. WE CHOSE TO REPLACE BOTH REAR TIRES. ON A RECENT VACATION TO FLORIDA FROM TEXAS, THE FRONT LEFT TIRE, SAME GOODYEAR TYPE TIRE, SEPARATED. OUR SPARE REPLACED THE FRONT LEFT TIRE. ON THE RETURN TRIP FROM FLORIDA BACK TO TEXAS (SAME VACATION), THE FRONT RIGHT TIRE BEGAN SEPARATING WHEN WE WERE ON THE EAST SIDE OF LOUISIANA. WE WERE UNABLE TO LOCATE AN OPEN TIRE STORE, AS IT WAS A SUNDAY. SO, WE DROVE HOME SLOWLY THE REMAINDER OF THE TRIP. AFTER RETURNING HOME, DISCOUNT TIRES (WHERE WE PURCHASED THE TWO NEW REAR TIRES IN FEB. 2014) ORDERED US TWO NEW FRONT TIRES. THE TIRES WERE SHIPPED FROM CHICAGO, DUE TO THE UNUSUAL SIZE OF THE TIRE (WE WERE TOLD). IS THE GOODYEAR WRANGLER TIRE A SAFETY HAZARD, SINCE THREE OUT OF THE FOUR TIRES FAILED? WAS IT THE 'LOT' THAT WAS BAD? WE WERE TOLD BY DISCOUNT TIRES THAT THERE WASN'T A RECALL ON THIS TIRE. *TR

Safety ratings

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.
