Recalls on the 2019 GMC Sierra 2500

the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

ELECTRICAL SYSTEM
On 07/10/2026 at approximately 1:10 a.m., the parked and unoccupied vehicle caught fire while turned off. The vehicle had not been driven for several hours. A neighbor was awakened by the horn/alarm and popping noises, observed fire near the passenger-side cab/engine area, and called 911. The fire rapidly spread throughout the cab, engine compartment, rocker-panel areas, wheel wells, and truck bed, creating an explosion hazard and threatening a nearby occupied residence and garage. The fire department extinguished the blaze, but the vehicle was completely destroyed. Before the fire, the vehicle had experienced recurring coolant warnings, a DEF-system warning, and delayed starting associated with the main battery. No smoke, fuel odor, intentional ignition source, charging device, or known external fire source was present before the incident. Weather was calm. The exact failed component and cause remain UNKNOWN. A firefighter stated that the apparent fire origin was near the passenger side of the vehicle. The remains are available for inspection, subject to coordination with the vehicle owner and insurer. The incident has been reported to the fire department, insurer, manufacturer, and NHTSA.

ELECTRICAL SYSTEM
The manufacturer placed two 12v batteries to start the truck with one being located on the passenger side just in front of the cowl of the cab. The factory OEM batteries are known to overheat when charging which is exactly what mine did and as the battery boils over with sulfuric acid, the acid is vaporized and ingested into the cabin. It’s a diesel so it’s common for me to take my dog in the rear crew cab with me and leave the engine running so the cabin will stay cool in the summer while I work my contractor job. When I let the engine idle with windows up and AC on the overcharged battery introduced the vaporized sulfuric acid into the cabin and rendered the interior deadly toxic. Luckily I was only gone from the truck for about 10 minutes but in this amount of time the acid was very bad and caused burns in my dogs throat and mine while driving home. I can only imagine if this scenario were to take place with kids left in the truck for many reasons to stay cool but could easily turn into a deadly situation. PLEASE look into this before someone or some poor animal is fatally injured or killed.

Vehicle was last driven on June 23 2024 and parked in my driveway. On the evening of June 29 2024 my horn was blowing in my truck at around 10:30. While I was walking out to the vehicle it was in flames. The fire started from what I understand on the driver’s side behind the dash. Luckily no one was in the vehicle when it happened.

POWER TRAIN
While merging into highway traffic the truck surged with RPM going to 5,000. Shortly after this event there was a grinding or rattling noise in the transmission bell housing along with unusual shifting behavior and a repeatble vibration + rotational noise between 50 and 60 MPH. The vehicle was brought to the dealer for inspection at least 4 times with claims they could not hear the obvious noise that did not go away. On the last drop off, I picked up the vehicle and the noise was gone but the shifting behavior and the constant vibration from the transmission still persists. The dealer said GMC would replace the transmission for approximately $10,000 but I would need to cover 50% of the cost. Vehicle had 35,700 miles on it and was 4 months beyond the 5yr warranty. Still unrepaired. No warning lamps, messages, or codes. Transmission component failure is imminent based on the vehicle behavior

The connectors to the fuel pump have failed causing the truck to mechanically fail and not operate. This is a common problem per the diesel technician who diagnosed our truck and in his opinion should not be happening as often as it does.

SEAT BELTS
Driver seat belt would not recoil. Took to Royal GMC of Tucson and they said it was not a warranty covered part and would not repair it unless I paid for the seat belt replacement. Obviously, I need a seat belt as a safety feature being the driver so I had them order the seatbelt and they installed it. See attached receipt. I believe this should be a warranty item from the manufacturer as it is defective and a serious safety issue. The vehicle is a 2019. I am the only one that drives this vehicle and I have never had any accidents etc.
