• 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.

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

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

• 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.

    GM TRANSMISSION CONTROL MODULE # 24256861.... There are over 9,000 GM trucks that are sitting idle because GM quit making this part, There are no after market replacements nationwide. When this part fails it shifts the transmission into 2-3 rd gear and goes into limp mode which if you are doing 70 on the interstate you are in for a sudden awakening. It also causes other issues like stablitrac issues there are at least 4 other issues which make the vehicle undrivable It is sad that GM has known of this failure for well over year. It should be a warranty item but is not. I just need my truck to be drivable again.....

    I was driving down the highway at 75 MPH when the Transmission Control Module overheat and put my truck into third gear causing the truck to speed unsafe.

  • Filed Sep 2014

    INITIALLY I FELT THE PROBLEM AS A SLIGHT "MISSING" IN THE ENGINE UNDER VERY LIGHT ACCELERATION BETWEEN 40 MPH AND 55MPH AND MORE PRONOUNCED UNDER CONSTANT THROTTLE GOING UP GRADES ON THE HIGHWAY AT A SPEED OF ~55 MPH (1400-1500 RPM). THE VEHICLE SEEMED TO BE "LUGGING", AND THEN THE RPM WOULD INCREASE BY ~20% IMMEDIATELY FOR A SHORT DISTANCE AND THEN DROP BACK (ALL AT CONSTANT THROTTLE) TO 1400-1500 RPM. WHEN DRIVING ON THE HIGHWAY IN CRUISE CONTROL AT 60 MPH AND GOING UP A GRADE, THE VEHICLE WOULD SHOW SIGNS OF "STRAINING" AND IMMEDIATELY INCREASE IN THE RPM BY ABOUT 20% WITH AN ATTENDANT ACCELERATION. THEN THE RPM WOULD INCREASE INSTANTLY BY ABOUT 1000 RPM AND THE VEHICLE ACCELERATES RAPIDLY UNTIL I ENGAGE THE BRAKES. MY DEALER OBSERVED THE SAME CHARACTERISTICS AND DETERMINED THAT IT WAS A TORQUE CONVERTER PROBLEM AND ON 07/25/2014 THEY INSTALLED A NEW TORQUE CONVERTER, WHICH PROVED TO HAVE NO EFFECT ON THE PROBLEM. I WAS INFORMED BY THE SERVICE MANAGER THAT GMC TECHNICAL SERVICES INFORMED HIM OF A SERVICE BULLETIN (#PIP4681D: RANDOM BUMP CHUGGLE OR FISHBITE SENSATION WHILE CRUISING AT APPROXIMATELY 1,300 RPM- OCTOBER 31, 2013) THAT ADDRESSED THE PROBLEM, AND FURTHERMORE NO FURTHER CORRECTIVE ACTION COULD BE TAKEN. ON AUGUST 6,,2014 I WAS DRIVING AT CONSTANT SPEED OF 60 MPH ON A MAJOR HIGHWAY IN "CRUISE CONTROL" AND MODERATE TRAFFIC. WHILE GOING UP A LONG GRADE FOLLOWING ANOTHER VEHICLE AT A SAFE SPEED, MY VEHICLE IMMEDIATELY JUMPED ~400 RPM AND THEN ABRUPTLY CHANGED TO A LOWER GEAR AND ACCELERATED SUDDENLY PUTTING ME AT RISK OF COLLIDING WITH THE VEHICLE AHEAD OF ME. I QUICKLY APPLIED BRAKES AND WAS ABLE TO AVOID AN ACCIDENT. I IMMEDIATELY CONTACTED GMC CUSTOMER SERVICES WHO OPENED A CASE NUMBER ([XXX]) AND ASSIGNED A REP. TO MY CASE. I HAVE SUBSEQUENTLY BEEN INFORMED OF THE GMC COMPANY LINE--"THE VEHICLE IS OPERATING AS DESIGNED", "LIVE WITH IT"!!! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

    HELLO, THE DATE AND MILEAGE ABOVE IS NOT ACTUAL DATE OF FIRST INCIDENT, BUT IS THE FIRST TIME I TOOK IT IN FOR THE FIRST OIL CHANGE AND VEHICLE INSPECTION WHICH ALSO WAS THE FIRST TIME I COMPLAINED TO THE DEALERSHIP ABOUT THE ISSUE. MY TRANSMISSION SLIPS BETWEEN 2ND AND 3RD GEAR AT LEAST 4 TIMES A MONTH. THE DEALER TOLD ME THAT IF I CANT PROVE IT OR IF IT DOESN'T DO IT WHEN THEY DRIVE IT THEN THEY CANT PERFORM A DIAGNOSTIC TEST TO FIX THE PROBLEM. THE SELLER WHO SOLD ME THE VEHICLE CALLED ME TWICE TO SEE HOW IM ENJOYING MY TRUCK AND I COMPLAINED TO HIM BOTH TIMES ABOUT THE ISSUE AND HE TOLD ME THE SAME THING ABOUT MY ISSUE. I EVEN LEFT VOICEMAILS TO HIM ABOUT IT AND HE NEVER RETURNED MY CALLS UNTIL I MADE A YEAR (3/16/14) OWNING MY TRUCK AND CLAIMS HE DON'T REMEMBER ME TELLING HIM THIS THE FIRST TIME. IM A STRONG GM FAN BUT I FEEL IM NOT BEING HELPED WITH MY ISSUE AND ITS ANNOYING THAT I HAVE TO DRIVE MY TRUCK CAUTIOUS GUESSING WILL IT SLIP THIS TIME OR WILL IT SLIP NEXT TIME? IF ITS PROFESSIONAL GRADE THEN WHY AM I HAVING THIS PROBLEM? I USE MY TRUCK FOR FAMILY VACATIONS AND I KNOW ANYONE WITH THE SAME PROBLEM WOULD NOT DRIVE THIS TRUCK FAR AWAY FROM HOME WITH THIS ISSUE. IT DOES IT WHEN IT WANTS TO BUT ITS JUST FUNNY HOW IM TRYING TO FIGURE OUT WHEN IT WILL DO IT AGAIN. I GET ALL THESE EMAILS ASKING ME TO RATE THE DEALERSHIP 5 STARS AND TO RATE THE TRUCK BUT I CANT EVEN GET MY TRUCK CHECKED OUT. THEN THEY TELL ME THEY WONT GIVE ME A RENTAL WHICH I WOULD NEED ANOTHER TRUCK AS A RENTAL. THIS IS SAD I SPEND 30 GRAND ON A TRUCK I CANT GET WORKED ON UNLESS I HAVE PROOF. *TR

    I OWN A 2013 GMC SIERRAHD 2500 AND I AM EXPERIENCING POWER STEERING FAILURES. GMC IS REFUSING TO FIX THE PROBLEM BECAUSE THEY CANT FIND IT. GMC ALSO HAS NO PROBLEM PUTTING ME BACK ON THE ROAD IN A DANGEROUS UNSAFE VEHICLE THAT IS STILL UNDER BUMPER TO BUMPER WARRANTY. . THE FIRST EXPERIENCE WAS JUST PULLING INTO A PARKING SPOT. AS I WAS TURNING, ALWAYS TO THE LEFT, INTO THE SPOT THE POWER STEERING FAILED. ALWAYS AFTER A LONG DRIVE THIS OCCURS, TO THE TUNE OF 5 PLUS HOURS. THE POWER LOSS REPEATED ITSELF TWO MORE TIMES THAT FIRST DAY. OCCURRING WHEN I WAS COMING TO A SLOW LEFT TURN UNDER 10 MPH. I TOOK IT TO THE DEALER A COUPLE DAYS LATER AND THEY COULDN'T REPEAT THE PROBLEM SO THEY REFUSED REPAIRS. THE NEXT TIME IT HAPPENED WAS A COUPLE DAYS AGO. THIS TIME IT BEGAN WITH SLOW LEFT TURNS IN A PARKING LOT OR ON DOWNRAMPS FROM HIGHWAYS. HOWEVER THE PROBLEM GAINED INTENSITY AS I THOUGHT I COULD FEEL IT WHILE DRIVING AT HIGH SPEEDS, ALTHOUGH I DIREGUARDED THAT SINCE IT IS HARD TO TELL WHILE DRIVING 65 ON THE HIGHWAY. ONCE I REACHED MY LOCAL BACK, CURVY, MOUNTAIN ROADS, IT FAILED REPEATEDLY. ONE INSTANCE CAUSING ME TO VEER TO THE EDGE OF A SEVERE DROP OFF AND MY TIRES RUNNING OFF THE ROAD. THIS EASILY COULD HAVE BEEN A FATAL MOMENT. AGAIN AFTER A LONG DRIVE, THEY WERE UNABLE TO RECREATE THE PROBLEM. THEY INSPECTED EVERYTHING AND RESEARCHED THE ISSUE. GMC SAID THAT WILL HAPPEN WHEN HITTING THE BRAKES AT A SLOW SPEED. HOWEVER, THE FAILURE HAS NOW OCCURRED WITHOUT BRAKING AND AT A NORMAL SPEED OF ABOUT 30 MPH. GMC REFUSED TO REPLACE ANYTHING AND WOULD NOT COMPENSATE THE DEALER IF THEY DID. THUS GMC PUT ME BACK ON THE ROAD IN A DANGEROUS VEHICLE. THEY SAID THIS WAS NORMAL AND WOULD HAPPEN FROM TIME TO TIME. DESPITE ALL THEIR EXCUSES, I HAD A CONTRADICTION FOR.I DON'T UNDERSTAND WHY IT DIDN'T START TILL NOW AND WHY AM I THE ONLY ONE HAVING THE PROBLEM. *TR

    I OWN A 2013 GMC SIERRA 4WD CREW CAB THAT IS HAVING BRAKING PROBLEMS. I PURCHASED THE VEHICLE ON 05/29/2013 NEW FROM BILL SMITH BUICK-GMC INC. LOCATED IN CULLMAN, AL AS A NEW VEHICLE AND AT THE TIME OF PURCHASE IT HAD 7173 MILES ON IT AS STATED ON THE ODOMETER DISCLOSURE STATEMENT. THE VEHICLE CURRENTLY HAS 41585 MILES ON IT THAT INDICATED I HAVE DRIVEN THE VEHICLE 36412 MILES. I HAVE HAD TWO INCIDENTS WITH THE BRAKES WHERE THE VEHICLE FAILED TO STOP WITH THE BRAKES FULLY APPLIED. THE FIRST TIME WAS WHEN THE VEHICLE HAD APPROXIMATELY 15000 MILES ON IT. THE SECOND TIME OCCURRED THIS PAST THURSDAY, DECEMBER 18, 2014 WHEN I APPLIED THE BRAKES AT 25 MPH AND THE CAR JUST CONTINUED TO ROLL UP HILL UNTIL I HIT A CAR IN FRONT OF ME. THERE WAS NO DAMAGE TO THE OLDER BUICK LASABER REAR END OR BUMPER BUT MY FRONT BUMPER WAS PUSHED IN ABOUT 2 INCHES. IF I HAD BEEN ON THE LEVEL OR WAS GOING ABOVE 25 MPH I SUSPECT THERE WOULD HAVE BEEN SUBSTANTIAL DAMAGE TO BOTH VEHICLES. WHAT?S HAPPENING IS WHEN THE BRAKE IS APPLIED THE CAR STARTS TO SHUDDER AND SOUNDS LIKE YOUR BANGING ON A TIN CAN. WHEN THAT HAPPENS THE TRUCK IS NOT STOPPING OR SLOWING AT ALL AND THE BRAKE PEDAL IS AS FAR DOWN AS IT CAN GO. PUMPING THE BRAKE WILL CAUSE THE BRAKES TO RECOVER AND THE VEHICLE WILL STOP. THIS PROBLEM HAS NOT BEEN A CONSISTENT ISSUE. THIS LAST THURSDAY IS THE FIRST TIME I COULDN?T STOP IN 26000 MILES. BACK WHEN THE VEHICLE HAD 15000 MILES ON IT THE SAME THING OCCURRED.

    TRUCK IS LEAKING OIL, AND I HAVE A SMALL PUDDLE OH GARAGE FLOOR. BROUGHT TO ORIGINAL SELLING DEALER TO BE CHECKED. THEY CLAIMED THERE WAS A PLUG ON BACK OF ENGINE THAT WAS LEAKING. THEY HAD VEHICLE FOR 3 1/2 DAYS, AND CLAIMED IT WAS FIXED. THEY HAD OVER 1 PAGE OF SEALS, GASKETS, PLUG WERE REPLACED. DROVE APPROXIMATELY 50 MILES, AND IT STARTED LEAKING EXACTLY THE SAME AS BEFORE. RETURNED TO DEALER AGAIN, AND WAS TOLD BY THE SERVICE TECHNICIAN THAT IT WAS NORMAL TO SEE IT HAVING A LEAK DUE TO THE SILICONE THAT WAS USED ON ENGINE PARTS WHEN IT WAS BUILT !!! I WAS ADVISED TO DRIVE IT FOR 1 WEEK AND BRING IT BACK AGAIN. AT THAT POINT IN TIME, I CONTACTED GM AND WAS TOLD TO GET A SECOND OPINION AT ANOTHER DEALERSHIP. I BROUGHT IT TO THEM ON 11/15/13. IT HAS BEEN THERE NOW FOR 6 DAYS. I WAS JUST TOLD THAT THEY HAVE 4 PAGES OF NEW PARTS THAT HAVE TO BE ORDERED TO REPAIR IT. THEY (DEALERSHIP) REQUESTED THAT GM REPLACE THE ENGINE AND WAS DENIED. CONSIDERING THIS IS THE 3RD TIME TRYING TO REPAIR THE SAME PROBLEM, THEY SHOULD EITHER RE-PURCHASE OR LEMON LAW THIS. *TR

    While driving carrying a full load in the back of the truck, the engine began to lose power, started running rough and then died without any warning within a matter of seconds. No indicator light or warnings were displayed. We were traveling in the number one lane during heavy traffic and had difficulty trying to stop with no power nearly causing an accident. We were left stranded in the fast lane of a large intersection during heavy traffic causing a large traffic jam. The vehicle was towed to a mechanic who found metal shavings throughout the fuel system indicating the high pressure fuel pump had disintegrated internally causing the metal shavings. I have asked the parts be saved for further inspection if necessary. The mechanic stated this type incident has occurred and is a well documented and known deficiency for this make and model of truck.

    MICE, RABBITS ETC. CHEWED THROUGH WIRES BECAUSE GMC PUTS PEANUT OIL ON THEIR WIRES. GMC DEALER SAID THEY WOULD FIX WIRES BUT THE PROBLEM WILL PERSIST BECAUSE PEANUT OIL IS BAIT FOR THESE ANIMALS. THIS IS A PROBLEM THAT WAS REPORTED ON A 2012 VEHICLE. THIS COULD CAUSE FIRES ETC AND NEEDS TO BE FIXED. THE VEHICLE WASN'T RUNNING RIGHT, ENGINE LIGHT WAS ON AND CHEWED WIRES WERE DISCOVERED. WERE TOLD BY GMC DEALER THERE IS NO PERMANENT FIX BECAUSE THEY USE PEANUT OIL BECAUSE ITS CHEAP! WE'VE ONLY HAD THE VEHICLE SINCE SEPTEMBER 2013. GMC WILL PUT THE WIRES TOGETHER AGAIN BUT NOT FIX THE MAIN PROBLEM OF THE PEANUT OIL. THIS IS A PROBLEM THAT IS COMPLETELY AVOIDABLE, YET A PROBLEM THAT IS BUILT INTO THE VEHICLE. *TR

    AT THIS OCCURRENCE THE HOOD LATCH DOES NOT KEEP THE HOOD TIGHT WHEN CLOSED. THE HOOD RATTLES AT SPEEDS OVER 35MPH AND APPEARS AS THOUGH IT IS GOING TO OPEN. AS A RESULT OF ATTEMPTING TO SUFFICIENTLY SECURING THE HOOD, I SUBSEQUENTLY DENTED THE HOOD. I HAVE HAD THE BODY DEPARTMENT AT THE LOCAL DEALERSHIP LOOK AT IT AND THEY FOUND THAT THE HOOD LATCH NEEDED TO BE ADJUSTED. AFTER ANOTHER 2500 MILES, THIS RATTLE HAS RETURNED. THE COMPLAINT IS THAT THIS IS THE SECOND 2013 SIERRA DENALI THAT I HAVE OWNED SINCE OCTOBER 2012, SINCE THE DEALERSHIP BOUGHT BACK THE FIRST ONE AFTER NUMEROUS PROBLEMS INCLUDING THE TRANSMISSION BEING REPLACED AT 6250 MILES AND NUMEROUS EFFORTS TO FIX THE HOOD.

    THE HEAD RESTS OF OUR NEW TRUCK (PURCHASED DEC 2012) PROJECT SO FAR FORWARD THAT IT FORCES MY HEAD TO TILT DOWNWARD. THERE IS NO FORWARD/BACK ADJUSTMENT TO THE HEAD REST, AND TURNING THE HEAD REST BACKWARDS TO MAKE IT BEARABLE MEANS IT NO LONGER WILL SERVE WELL TO PREVENT NECK INJURIES IN A CRASH. FOR SHORTER DRIVES, THE FORCED HEAD TILT IS UNCOMFORTABLE, BUT FOR LONGER DRIVES IT CAUSES ENOUGH PAIN THAT I HAD TO SEE A CHIROPRACTOR (AND I'M AN ATHLETIC, HEALTHY PERSON!). THE DEALER AND MANUFACTURER CONTEND IT WORKS AS DESIGNED FOR SAFETY IN A CRASH. BUT IF I CAN'T SIT IN IT FOR NORMAL DRIVING WITHOUT EXPERIENCING NECK/BACK PAIN, HOW "SAFE" IS THAT? I NOTICED THE NEW 2014 GMC 1/2-TON PICKUPS HAVE A HEAD REST WITH A NOTICEABLY LESS ANGULAR DESIGN, INDICATING GMC RECOGNIZED THE HEAD REST DESIGN IN MY 2013 3/4-TON TRUCK IS, AT BEST, A POOR ONE AND, AT WORST, A POTENTIALLY DANGEROUS ONE. IS THERE ANY RECOURSE TO GETTING GMC TO REPLACE MY HEAD RESTS WITH THE NEW DESIGN (OR EVEN AN OLDER ONE, LIKE THE STRAIGHT-UP-AND-DOWN ONES I HAVE IN MY 2003 CHEVY TAHOE)? *TR

OF COURSE THE FEDERAL GOVERNMENT WILL DO NOTHING EXCEPT PROVIDE GMC WITH MORE TAXPAYER-FUNDED BAILOUT MONEY!

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.
