  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.

  General Motors, LLC (GM) is recalling certain 2016-2018 GMC Sierra 3500 and Chevrolet Silverado 3500 trucks equipped with gasoline engines and dual fuel tanks. The fuel-level sensor in the front tank may stick in a low-level position, allowing 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.

    I’ve heard all the horror stories about faulty electrical issues. I’m chasing an issue now on my 2018 with ONLY 87,000 miles after spending a bunch of money on batteries hub assemblies random control modules to try to fix an issue of stabilitrak, traction control, abs, trailer brakes, power steering etc all going off every 3 seconds. Grounds have all been re done to bare metal nothing is fixing the issue. Steering wheel about flew out of my hands going 65mph when the power steering message along with all the others on the dtc while dinging annoying the shit out of me. I’ve bought nothing but gm trucks my whole adult life and I’ll never do it again. Thing is a piece of shit and you all should be doing something to fix it. I’ve seen people have the fix by replacing a tail light bulb speed sensors ecbm abs modules trailer brake modules harnesses the list is endless. Someone is going to die when they crash from some bullshit electrical problem that can’t be chased down because it’s always something different. The money we pay for these trash trucks is insane for the problems like this that you won’t recall. That’s it these trucks suck and I’ll never buy another one. Trash.

    WHILE PULLING A VARIETY OF 3 DIFFERENT TRAILERS, THE INTEGRATED TRAILER BRAKE CONTROL DOES NOT PROPERLY SEND OUTPUT TO THE TRAILER BRAKES. THIS CAUSES THE TRUCK (TOW VEHICLE) TO DO ALMOST ALL OF THE BRAKING WORK ON ITS OWN. ON MULTIPLE OCCASIONS I'VE HAD THE ANTI LOCK BRAKES ACTIVATE ON THE TRUCK WHILE TRYING TO STOP AT A TRAFFIC LIGHT BECAUSE I WASN'T GETTING ADEQUATE BRAKING FROM THE TRAILER DUE TO THE INTEGRATED TRAILER BRAKE CONTROL FAILING TO SEND ADEQUATE POWER TO THE TRAILER BRAKES. THE GAIN ON THE TRAILER BRAKE CONTROL WAS SET PROPERLY FOR THE LOAD BEING PULLED ON THE TRAILER AND THE GROSS COMBINATION WEIGHT OF THE TRUCK/TRAILER/LOAD DID NOT EXCEED THE RATED CAPACITIES OF THE TRUCK OR TRAILER. THE TRUCK HAS BEEN TO 2 DIFFERENT CHEVROLET DEALERS AND BOTH OF THEM HAVE TRIED BLAMING THE TRAILER OR THE OPERATOR. I HAVE SHOWN BOTH DEALERS THAT THE TRUCK DOES IT WITH A VARIETY OF DIFFERENT TRAILERS AND PROVEN THAT IT'S NOT THE TRAILER. I HAVE MY CLASS A CDL AND HAVE BEEN PULLING TRAILERS WITH BRAKE CONTROLLERS FOR 20 YEARS. THIS INSTANCE HAPPENS AT ALL DIFFERENT SPEEDS OF TRAVEL WHILE DRIVING, WHETHER IT BE 5 MPH OR 65 MPH OR ANYWHERE IN BETWEEN. ALSO, WHILE SITTING STILL AT A TRAFFIC SIGNAL, THE TRUCK PUTS NO BRAKING POWER TO THE TRAILER WHICH IS HORRIBLE WHEN YOU ARE SITTING ON ANY KIND OF SLOPED GRADE. FROM A COMMERCIAL DRIVER STANDPOINT, THIS TRUCK DOES NOT IN ANY WAY SHAPE OR FORM PASS A DOT SAFETY INSPECTION DUE TO THIS ISSUE. THE TRUCK HAS ROUGHLY 37,000 MILES, IS WELL TAKEN CARE OF, AND IS FLEET MAINTAINED. THE ATTACHED PHOTO IS WHILE SITTING STILL WITH A LOADED GOOSENECK TRAILER HOOKED TO THE TRUCK.

    WHEN THE TRUCK IS TURNED OFF IT SOMETIMES CAN TAKE ANYWHERE FROM 2 MINUTES TO OVER 1 HOUR TO RESTART. WHEN THIS ISSUE OCCURS AND THE KEY IS TURNED TO START THE VEHICLE ALL YOU WILL HEAR IS A "CLICK" SOUND COMING FROM WHAT I ASSUME IS THE STARTER. WHILE NOT STARTING, EVERYTHING ELSE ELECTRICAL IN THE VEHICLE SEEMS TO BE WORKING FINE. ALTHOUGH THIS TRUCK WAS DELIVERED NEW IN DECEMBER OF 2017(BUILD DATE OF 8/17), IT WAS NOT PUT ON THE ROAD AND IN SERVICE(BUILT OUT AS A TOW TRUCK) UNTIL MID MAY OF 2018. ALTHOUGH THIS STARTING ISSUE DID NOT BEGIN WITH MY TRUCK UNTIL SOMETIME IN FEBRUARY/MARCH 2019, WE HAVE ANOTHER TRUCK THAT IS THE EXACT SAME MODEL (BUILD DATE OF 2/18) THAT HAS BEEN EXPERIENCING THE SAME ISSUE FOR ABOUT 7 MONTHS NOW. THAT SECOND TRUCK WAS FINALLY TAKEN TO THE DEALER AND THEY COULD NOT FIND A SPECIFIC PROBLEM SO THEY REPLACED THE STARTED. THE PROBLEM STILL EXISTS. THE DRIVER RECENTLY REPLACED THE BATTERY JUST TO TRY TO ELIMINATE THE POTENTIAL CAUSE OF THIS ISSUE BUT THAT YIELDED NO POSITIVE RESULTS EITHER. WE ARE AT A LOSS AND THIS ISSUE IS LITERALLY COSTING US MONEY!! IN GENERAL, THIS NON-STARTING ISSUE HAPPENS A COUPLE TIMES A WEEK.

I’ve bought nothing but gm trucks my whole adult life and I’ll never do it again. Thing is a piece of shit and you all should be doing something to fix it. I’ve seen people have the fix by replacing a tail light bulb speed sensors ecbm abs modules trailer brake modules harnesses the list is endless. Someone is going to die when they crash from some bullshit electrical problem that can’t be chased down because it’s always something different. The money we pay for these trash trucks is insane for the problems like this that you won’t recall. That’s it these trucks suck and I’ll never buy another one. Trash.

    MY 3500 HD SRW HAS A POWER FOLD BUTTON FOR THE SIDE MIRRORS. WHILE PASSING A SEMI TRUCK AT 70 MPH ON I-20, I WENT TO ADJUST THE RIGHT MIRROR SLIGHTLY. I ACCIDENTALLY PUSHED THE POWER FOLD BUTTON ( IT IS LOCATED BETWEEN THE LEFT AND RIGHT MIRROR ADJUSTMENT BUTTON ON THE DRIVER SIDE DOOR ). THE SIDE MIRRORS FOLDED IN. I TRIED TO RETURN THE MIRRORS BACK TO THEIR OPERATING POSITION BUT THEY WOULD ONLY UNFOLD A SLIGHT AMOUNT DUE TO THE WIND RESISTANCE. SINCE I WAS PULLING MY FIFTH WHEEL MY REAR VIEW MIRROR WAS USELESS. I DID NOT HAVE ANYONE WITH ME AT THE TIME TO HELP FORCE THE MIRROR OUT SO I AM NOW COMPLETELY BLIND AND BESIDE A SEMI IN THE LEFT HAND PASSING LANE. THIS WILL EVENTUALLY GET SOMEONE HURT SERIOUSLY. YOU CAN NOT PULL OVER SINCE YOU ARE IN THE LEFT LANE, CAN NOT SLOW DOWN SINCE YOU ARE ON AN INTERSTATE HWY AND HAVE NO SIGHT ON THE RIGHT SIDE OF YOUR VEHICLE.

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.
