On December 29, 2022 I stopped at the bank for 2 minute and when I got back to my truck I noticed smoke coming out from under the hood. I immediately called 911 and luckily some nice people were able to get my hood up safely and the bank provided a fire extinguisher before the fire trucks arrived. It was engulfed in flames. The fireman said it appeared the fire started in the wiring at the engine. I had a recall fixed a while back for the engine block heater so I was worried maybe they didn’t repair the recall. A week after the fire I received a 2nd recall in the mail for the same recall. Today is July 9th and my truck is still in the shop waiting on parts that have been on back order this whole time. GMC told my insurance company they were sending someone down to look at it. Never heard anything back. This could have been so bad had I been driving it when the fire started. So here I am going on 7 months without my truck all while paying $942/month. I just want something to be done to speed up the repairs that my insurance has paid. Estimate is $22,000

COOLANT LIGHT CONTINUES TO COME ON. I'VE HAD IT TO THE SHOP AND THEY SAY THAT IT IS A MANUFACTURING PROBLEM. HOWEVER THEY ARE NOT WILLING TO FIX IT. I HAVE THE SAME PROBLEM ON MY CHEVY HIGH COUNTRY THAT HAS THE SAME 6.6 DIESEL ENGINE IN IT. THE MECHANICS ALL ACKNOWLEDGE THAT THIS IS A PROBLEM FOR ALL OF THESE MODEL 6.6 DIESEL REGARDLESS OF WHETHER IT IS GMC OR CHEVY. THIS SHOULD DEFINITELY BE A RECALL. THE WARNING LIGHT CONTINUALLY COMES UP ON THE DISPLAY SAYING I AM LOW ON FLUID. HOWEVER, WHEN I CHECK IT IT IS ALWAYS FULL. THERE IS A HIGH CHANCE THAT IF IT IS LOW I WILL AUTOMATICALLY RESET IT THINKING THAT THE WARNING LIGHT IS NOT FUNCTIONING CORRECTLY. AGAIN, THE GM TEXT KNOWS THAT THIS IS A PROBLEM THROUGHOUT THE FLEET. AGAIN, THIS SHOULD BE A RECALL. IF YOU HAVE FURTHER QUESTIONS YOU CAN REACH ME AT [XXX] THANK YOU FOR YOUR TIME, [XXX].

GMC HAS REFUSED TO FIND A FIX FOR THE HEATER CORD DEFECT WHICH IS ONE OF THE MAIN REASON WHY I PURCHASED THE VEHICLE. I LIVE IN IDAHO. GMC SHOULD COMPENSATE OWNERS UNTIL FIXED.

MY 2017 GMC 2500 SIERRA DENALI DURAMAX HAS HAD THIS THROTTLE ISSUE, IT SEEMS TO ONLY DO IT WHEN THE EXHAUST STINKS, AND AT SPEEDS BETWEEN 5 - 55 MPH. IF I TAKE MY FOOT OFF THE ACCELERATOR THE TRUCK MAINTAINS RPM (1200 - 1400) OR EVEN HAS INCREASED SOME AND HAS LASTED 2 - 5 SECONDS (ESTIMATED AND GREATLY REDUCES THE EFFECTIVENESS OF THE BRAKING CAPACITY AND RESPONSIVENESS/STOPPING DISTANCE). WORST WAS WITH A HUGE TRAILER BEHIND AND I GOT UP TO SPEED 55 ON COUNTY HWY 8, AND I LET OFF THE ACCELERATOR AND IT KEPT GOING HARD AND I GOT ON THE BRAKES AND I COULDN'T SLOW IT DOWN UNTIL THE TRUCK DECIDED TO RELEASE OFF THE THROTTLE.(TWO WITNESSES IN THE VEHICLE, ONE A GM TECH, STATING YOUR VEHICLE IS NOT SAFE AND NEEDS TO BE LOOKED AT) IT'S HAPPENED ABOUT 25 TIMES IN 5700 MILES IN VARIOUS SETTINGS & SPEEDS AND HAS OCCURRED FREQUENTLY IN TOWN AT SPEEDS OF 25 - 35 MPH. THERE MAYBE SEVERAL HUNDRED MILES IN BETWEEN EPISODES IF YOU WILL, AS THEY OCCUR IN CLUSTERS WHEN EXHAUST STINKS AND GONE WHEN EXHAUST DOES NOT STINK. TRUCK ALSO HAD TORQUE CONVERTER NOT UNLOCK AND [XXX] NEAR CHOKED THE ENGINE OFF AT STOP SIGN RIGHT AFTER A THROTTLE STUCK CONDITION. GOT HOME THE OTHER NIGHT AND FUEL GAUGE STOPPED WORKING! BACK UP CAMERA IS DAYLIGHT BRIGHT AT NIGHT, LOW COOLANT ISSUES, MAP SENSOR ISSUE, ENGINE SURGED THE OTHER DAY, WHAT NEXT? IT'S CONSTANTLY BEEN AT DEALERSHIPS WITH NO ANSWERS. MY WIFE WON'T DRIVE IT ANYMORE AND WISHES I WOULDN'T EITHER FEARING IT WILL CAUSE AN ACCIDENT AND SHE'S PROBABLY RIGHT. GM HAS STATED THEY ARE AWARE OF THE PROBLEM BUT WILL NOT PROVIDE ANY TRADE IN ASSISTANCE DOLLARS TO GET IT OFF THE ROAD AND THERE IS NO FIX. $70,000+ TRUCK, LIVES AT RISK AND NO SERIOUS RESPONSE FROM GM?

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2017 GMC Sierra 2500 Hd verdict →
