2017 GMC Sierra 3500HD

Recalls and owner complaints reported to NHTSA

Compared with the typical (middle) count of 245 complaints across the 8 model-year 2017 heavy-duty trucks we cover. Best-selling trucks naturally collect more complaints because more of them are on the road.

What owners should know

Covers 2015–2019 · 6.6L Duramax diesel (LML 2015–2016, L5P 2017–2019) and 6.0L V8 gas · Updated 2026-10-01

The Chevy Silverado HD and GMC Sierra HD are mechanically the same trucks, so these notes cover both, in 2500HD and 3500HD. The diesel changed partway through: the Duramax LML in 2015–2016, and the redesigned Duramax L5P in 2017–2019. Gas trucks use the 6.0L V8.

We counted 1,326 owner complaints filed with NHTSA for 2015–2019 Silverado HDs and Sierra HDs: 413 from LML diesels, 311 from L5P diesels and 512 from gas trucks (identified by VIN). Complaint counts show what owners report most often, not how many trucks have a problem.

At a glance

  • 2015–2016 diesels (LML) carry the high-pressure fuel pump (CP4.2) risk.
  • 2017–2019 diesels (L5P) use a different fuel pump and have far fewer fuel pump complaints. Block heater cord recalls address a fire risk.
  • Brake pedal recall on 2015–2016 trucks: the pedal can come loose.
  • Trailer brake warnings are frequently reported.
  • Gas trucks: the transmission is the most common complaint (about 1 in 5).

2015–2016 Duramax LML: fuel pump

Fuel pump problems come up in 61 of 413 LML complaints, about 3 times the rate of the 2017–2019 L5P (16 of 311). The LML uses the Bosch CP4.2 pump. When it fails, metal can contaminate the whole fuel system, and repair sources report bills of $8,000 to $15,000. There was no recall.

When buying a 2015–2016 diesel: ask whether the pump was replaced or upgraded, and for fuel filter records.

2017–2019 Duramax L5P

Generally well regarded. Commonly reported repairs include DEF tank sensors, the MAP sensor, plastic intercooler pipes, and the #4 fuel injector connector (GM bulletin 23-NA-027). Fire comes up in 30 L5P complaints. GM recalled 2017–2019 diesels because the engine block heater cord can short and overheat (recalls 19V328000 and 21V496000). Confirm both are done.

Brakes and trailer brakes

  • GM recalled 2015–2016 trucks because the brake pedal pivot nut can loosen, making the pedal loose or inoperative (recalls 16V069000 and 18V578000).
  • Owners frequently report "Service trailer brake system" warnings that can cut the trailer brakes while towing. If you tow, test the trailer brake controller with a trailer connected.

Gas trucks

The 6.0L engine is simple and long-lived. Transmission complaints are the top topic on gas trucks (99 of 512). Test-drive for harsh or slipping shifts.

Other recalls

  • Dual fuel tank sensors and a rear tank that can collapse on some diesels (recalls 19V088000 and 23V047000)
  • Front seat belt retractors on 2017–2018 trucks (recall 17V567000)
  • Several airbag recalls, including roof-rail and side curtain inflators

Common failures & how to fix them

Parts and video buttons search for your 2017 GMC Sierra 3500HD. Always confirm a part fits using your VIN. Brakes, steering, fuel and airbag work affects your safety, so if you're not sure, have a qualified mechanic do it.

  • 2015–2016 Duramax 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.

  • Loose brake pedal (2015–2016)

    Dealer (recall)

    Signs: The brake pedal feels loose or doesn't work right.

    Fix: Covered by GM recalls for the brake pedal pivot nut.

    May be covered free by recall 16V069000 / 18V578000. Check the VIN at nhtsa.gov/recalls.

  • Block heater cord fire risk (2017–2019 diesels)

    Dealer (recall)

    Signs: A burnt or melted block heater cord or plug.

    Fix: Covered by GM recalls. Don't use the block heater until it's checked.

    May be covered free by recall 19V328000 / 21V496000. Check the VIN at nhtsa.gov/recalls.

  • 'Service trailer brake system' warning

    Easy DIY

    Signs: Trailer brake warnings that cut the trailer brakes while towing.

    Fix: Start with the simple things: clean and inspect the 7-pin trailer connector and the trailer's wiring. If it continues, have a dealer check the trailer brake module.

  • L5P cracked intercooler pipe

    Easy DIY

    Signs: A loud pop, then low power and limp mode.

    Fix: Replace the plastic charge pipe. Many owners upgrade to a metal pipe.

  • Fuel System, Gasoline:Storage:Tank Assembly

    Feb 2019 · #19V088000

    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.

    Fix: GM has notified owners, and dealers will replace the rear-tank fuel-pump module, inspect the front tank and, if necessary, replace the front tank, free of charge. The recall began July 30, 2019. GM's number for this recall is N182204190.

    Sep 2017 · #17V567000

    General Motors (GM) is recalling certain 2017-2018 Chevrolet Silverado 2500 and 3500 and GMC Sierra 2500 and 3500 trucks. The front seat belt retractor assemblies were built with the incorrect torsion bar. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 209, "Seat Belt Assemblies."

      HAVE HAD THIS INTO THE DEALER AT THE FIRST OIL CHANGE AND COMPLAINED ABOUT TRANSMISSION SHIFTING ISSUES AND IT BEING UNSAFE TO DRIVE. COMPLAINTS ARE: HARD SHIFT, IT CLUNKS BOTH UPSHIFTING AND DOWNSHIFTING. GOING AROUND CORNERS FROM A STOP THE TRUCK WILL EITHER FALL ON ITS FACE OR JERKS YOU VIOLENTLY FORWARD. IN STOP OR GO TRAFFIC IT IS UNSAFE AND HAPPENS VERY FREQUENTLY- IT RANDOMLY ACCELERATES (JUMPS) QUICKLY ON ITS OWN WITH SLIGHT PEDAL PRESSURE TO THE POINT WHERE YOU CONSTANTLY HAVE TO BE AWARE AND HAVE YOUR FOOT NEAR THE BRAKE OR YOU CAUSE AN ACCIDENT BY REAR ENDING THE CAR IN FRONT, ITS AS IF THE TRANSMISSION ELECTRONICS GET CONFUSED ON HOW TO ACT. FEEL SHUDDERING FROM TRUCK'S MOTOR WHERE COLUMN SHIFT LEVER WOULD SHUDDER VIOLENTLY WHERE I WAS AFRAID IT WOULD VIBRATE OUT OF POSITION. ROUGH IDLE IS INCONSISTENT AT LOWER SPEED WHERE YOU SEE TACH GOING UP AND DOWN. STARTING COLD YOU GIVE IT AN EASY PEDAL TO MOVE AND WOULDN'T GO. TRANS DOESN'T KICK IN UNTIL YOU PRESS HARDER AND SOMETIMES WILL LUNGE. HAVE TAKEN INTO THE VARIOUS DEALERS 5-6 TIMES, VALVE BODY CHANGE, ENGINE MOTOR MOUNTS CHANGE AND DEALERS CAN FIND NO FIX. GM POWERTRAIN WAS EVEN INVOLVED WITH NO HELP. COMPLAINED TO THE GMC HOTLINE AND THEY SAID NEED 12,000 MILES ON TRUCK BEFORE THE TRUCK KNOWS HOW TO DRIVE BECAUSE OF THE 'SMART' TRANSMISSION WHERE IT LEARNS YOU'RE DRIVING HABITS. COMPLAINED THERE ARE 2 OF US THAT DRIVE IT HOW CAN IT LEARN EACH INDIVIDUALS DRIVING WHEN IT DOESN'T REALLY KNOW WHO IS DRIVING. THEY FINALLY SAID THERE IS NOTHING THAT CAN BE DONE FOR IT, THAT IS THE WAY IT IS. THIS ALL HAPPENS SPORADICALLY IN BOTH CITY LOW SPEED DRIVING AND HIGHWAY DRIVING, TURNING, BACKING UP OR GOING FORWARD FROM PARKING. BECAUSE OF THESE ISSUES, DIDN'T REALLY DRIVE THE TRUCK MUCH BECAUSE OF THE PROBLEMS.

      Brake are very spongy all the time we’ll While driving in parking lot at low speed we lost brakes happen to hit person in front. This has been a continuous problem to point we are scared to even use the truck to go to store. Took it to Firestone. They told me it was the master cylinder. So they replaced that, replaced the front rotors and pads, did a fluid exchange abs as well? Don’t know what that is. On the internet there is tons of this issue. I even see GMC 1500 is having this issue and there is a recall for the recalibration electric brake controller? Couldn’t it include the full Sierra line?. Why not on the 2500, 3500? Looks to be same system? Rotors and calipers are different thats it If anyone can help please let me know. It’s not covered under warranty and they want to replace some pump for $1500. I just paid $1500 for something totally different

      My truck is affected by GM’s engine block‑heater safety recall (NHTSA 21V‑496 / GM N212329840) addressing a risk of short circuit and potential engine‑compartment fire at the heater cord/terminal connection. GM’s interim action has been to remove/disable the block‑heater cord, which my dealer did, and then marked the recall “completed.” As a result, the NHTSA VIN tool shows 0 unrepaired recalls, even though no actual repair/restored functionality exists and GM continues to advise owners not to use the block heater until parts are available. Safety concern / impact: I live in a cold‑weather area and purchased this diesel expecting a functioning block heater for reliable cold starts. Disabling the heater has removed an intended cold‑weather safety/starting aid for multiple winters without a final fix. GM’s bulletin explicitly allowed dealers to disable the cord to close the recall, rather than provide a repair, leaving owners without the feature indefinitely. Suspiciously, I have also had to replace glow plugs on this truck sooner than traditional wear / failure rates would demand - including one glow plug that has been replaced twice in short span of time (should have lasted years). I continue to monitor GM’s recall portal; still no parts/remedy schedule. Please review whether GM’s chosen remedy—disabling a safety‑related feature and closing the recall—is adequate and within a reasonable time under the Safety Act. If not, I request NHTSA open a Recall Query into remedy adequacy and timeliness so owners receive a real repair (replacement heater/cord/connector) or appropriate alternative remedies.

      I HAVE A 2017 GMC SIERRA DENALI 1500. I BOUGHT IT NEW AND IT HAS VERY, VERY LOW MILEAGE. AT VARIOUS SPEEDS THERE IS A VIBRATION. FEELS LIKE I AM DRIVING OVER RUMBLE STRIPS. I HAVE ALWAYS NOTICED IT BUT MOSTLY THOUGHT IT WAS JUST SPOTS ON THE ROAD THAT WERE CAUSING IT. I STARTED TO DO A LITTLE RESEARCH AND LEARNED THAT THIS IS A KNOW ISSUE IN CHEVROLET AND GMC TRUCKS. NUMEROUS STORIES OF DEALERS IGNORING IT, COMPLAINTS ON MANY FORUMS, WHOLE WEBSITE DEDICATED TO IT, A NUMBER OF CLASS ACTION LAWSUITS, AND REPORTS TO THE NHTSA. LITERALLY THOUSANDS OF OWNERS ARE INVOLVED. GM HAS ISSUED A PRELIMINARY INVESTIGATION SERVICE BULLETIN (BULLETIN NO.: PI1354I), BUT DEALERS WANT TO CHARGE FOR DIAGNOSING AND POSSIBLY REPAIRING THIS MANUFACTURER'S DEFECT.

      THE VEHICLE EXHIBITS VIBRATIONS THAT CAN BE RATHER EXTREME AT TIMES. IT SEEMS TO BE MOST NOTICEABLE IN THE 70-75 MPH RANGE BUT CAN SOMETIMES BE FELT AT OTHER SPEEDS. IT FEELS LIKE THE VIBRATION ORIGINATES FROM THE REAR OF THE VEHICLE. TWO DEALERSHIPS HAVE REPLACED MULTIPLE PARTS AND HAVE PERFORMED NUMEROUS ALIGNMENTS AND ROAD FORCE BALANCES BUT CAN NOT IDENTIFY/REMEDY THE PROBLEM. THERE ARE THOUSANDS OF COMPLAINTS ON MULTIPLE ONLINE FORUMS OF THIS SAME ISSUE FOR 2014-2015 GM 1500 SERIES PICKUP TRUCK. SO FAR THERE HAS BEEN NO FIX FOR THEM EITHER. GM TREATS IT AS AN ANNOYANCE IN THE COMFORT OF THE RIDE, HOWEVER IF THEY CAN NOT IDENTIFY THE ISSUE HOW DO THEY KNOW IT IS NOT A SAFETY RISK.

      WHILE DRIVING DOWN A MOUNTAIN ROAD WITH A 5TH WHEEL ATTACHED IT APPEARED THAT THE REAR BRAKES ON THE DRIVERS SIDE WERE SMOKING, I PULLED OVER TO ALLOW IT TO COOL. WE FOUND A GMC DEALERSHIP AND PROCEEDED THERE VERY SLOWLY STOPPING A NUMBER OF TIMES TO ALLOW THE BRAKES TO COOL DOWN. 2 MILES SHORT OF GMC, THERE WAS A LOUD POP AND A TIRE HAD BLOWN. WE PULLED OVER AND WHILE CALLING ROADSIDE ASSISTANCE NOTICED FIRE UNDER THE TRUCK. WE PUT IT OUT WITH A FIRE EXTINGUISHER BEFORE THE FIRE DEPARTMENT ARRIVED. WE WERE TOWED TO THE DEALERSHIP. THE BRAKE CALIPER CAME APART, THE REAR AXLE BROKE (POSSIBLY MELTED FROM HEAT AND FIRE?). GM INITIALLY STATED 4 DAYS TO REPAIR, NOW THEY THEY ARE SAYING 3 WEEKS AS THEY HAVE TO BUILD A NEW AXLE. IF WE HAD NOT HAD THE EXTINGUISHER THE TRUCK, RV AND MEADOW WOULD HAVE ALL GONE UP IN FLAMES AND WHO KNOWS THE DISASTER THAT COULD HAVE OCCURRED IF THIS HAPPENED ON THE MOUNTAIN ROAD. THIS VEHICLE ONLY HAS 17,000 MILES, 11 MONTHS OLD AND HAS HAD ALL ROUTINE MAINTENANCE PERFORMED AT GMC DEALERS. I HAVE MORE PICTURES BUT AM UNABLE TO UPLOAD THEM.

      THE HEADLIGHTS ON MY NEW GMC SIERRA 2500HD DENALI ARE HORRIBLE AND UNSAFE FOR DRIVING AT NIGHT. THE 25 WATT RATING AND 2,000 LUMENS ON THE OEM HID BULBS DO NOT PROVIDE ADEQUATE, SAFE LIGHTING FOR OPERATING MY VEHICLE. I ALREADY HIT A DEER WITH MY BRAND NEW TRUCK BECAUSE I COULDN'T SEE IT WELL ENOUGH IN ADVANCE OF THE COLLISION. GMC SHOULD BE HELD ACCOUNTABLE FOR PUTTING SUCH A LOW POWER, POOR QUALITY AND UNSAFE HEADLIGHT IN THEIR $70,000 VEHICLES. I'M RENTING A HYUNDAI WHILE MY TRUCK IS BEING REPAIRED AND THE HEADLIGHTS ON THIS $30,000 FOREIGN CAR ARE 10XS BETTER THAN THE ONES ON MY TRUCK. WHY?

      FIRST AND MOST IMPORTANTLY MY BRAKES ARE MY MAIN ISSUE AND SAFETY PROBLEM. I NEARLY RAN INTO THE CAR IN FRONT OF ME AT A BUSY INTERSECTION. MY TRUCKS BRAKES LOSE PRESSURE AFTER THE FIRST INITIAL STOP COMING TO ANY TRAFFIC LIGHTS, STOP SIGN, SLOW TRAFFIC, PARKING LOTS ETC... NO MATTER HOW SLOW OR FAST THE TRUCKS MOVEMENT IS. FIRST BREAK ATTEMPT IS OK BUT 2ND STARTS LOSING PRESSURE AND 3RD ATTEMPT IS COMPLETE LOST OF PRESSURE ANF AND THE TRUCK JUST ROLLS UNTIL IT SLOWLY COMES TO A STOP. I WORRY ABOUT THE SAFETY OF MYSELF AND OTHERS MOTORIST REGARDING THIS ISSUE. MY SECOND COMPLAINT IS MY DRIVER SIDE MIRROR. EVERY TIME I GET INTO MY TRUCK AND START IT. MY DRIVER SIDE MIRROR MOVES OUT OF ITS SETTING AND I CONSTANTLY HAVE TO FIX IT.
