A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

ELECTRICAL SYSTEM
The engine coolant temperature sensor has failed on my 2019 GMC Canyon. The check engine light is illuminated, the temperature gauge does not register correctly, the air conditioning has been disabled by the vehicle's computer, and the engine cooling fan continues to run after the engine is turned off. These symptoms are consistent with the vehicle entering fail-safe mode due to loss of a valid coolant temperature signal. The problem was confirmed by an independent mechanic who diagnosed a failed coolant temperature sensor. The mechanic attempted to source a replacement part through GMC but was informed the part was unavailable. The reason for the parts unavailability is unknown, though in his experience, it typically means that the manufacturer is stocking up and preparing for a recall This issue appears to be widespread across 2017–2020 GMC Canyon and Chevrolet Colorado V6 trucks based on extensive owner forum documentation. The safety concern is significant: without reliable coolant temperature monitoring, there is no assurance the engine is operating within safe thermal limits, and the driver has no warning if overheating occurs. The disabled A/C also creates a safety risk during periods of extreme heat. The vehicle has approximately 60,000 miles. The problem has been present for approximately three months and is ongoing.

POWER TRAIN
Transmission shifting issues. The transmission will shift very slowly (engine revs high and vehicle lurches) when driving the truck each morning. I reported the issue to the dealership within 0ne month of purchasing the truck in 2019 and again in 2024. The dealership stated there is nothing wrong with the transmission. The transmission is now starting to slip at low/moderate speeds when accelerating. The vehicle has less than 50,000 miles.

Formal Complaint to NHTSA: 2019 GMC Canyon Transmission Issue To Whom It May Concern at the National Highway Traffic Safety Administration (NHTSA): I am writing to formally report a recurring and dangerous transmission issue in my 2019 GMC Canyon, and to request that NHTSA open an investigation into why General Motors has not issued a safety recall — despite widespread complaints and technical service bulletins. My vehicle exhibits jerking, hesitation, slipping, and hard shifting — especially during acceleration or when moving from a complete stop. These symptoms are consistent with hundreds of other consumer reports across forums, NHTSA complaints, and class-action lawsuits tied to GM’s 8L45 8-speed automatic transmission. I was quoted approximately $5,700 for a transmission repair and $8,800 for replacement. This problem is not simply an inconvenience or comfort issue. Hesitation and sudden surges in acceleration pose a legitimate safety hazard, especially when merging onto highways, pulling into traffic, or driving on slippery roads. At times, I’ve experienced delayed throttle response and unexpected lurching — which could easily result in a rear-end collision or intersection mishap. Despite the well-documented nature of this defect, GM has not recalled these transmissions — and owners are left to bear the financial burden of expensive repairs on a known design flaw. That is unacceptable. NHTSA’s mandate is to protect consumers from safety-related defects. In my view, and in the experience of many other drivers, this transmission issue meets the criteria for a recall: - It affects safe operation and control of the vehicle - It has been confirmed by internal GM service documentation - It recurs even after manufacturer-prescribed remedies - It places drivers, passengers, and others at risk Please consider this a formal request to investigate this matter and hold General Motors accountable for a recall or reimbursement program for affected consumers.

FUEL/PROPULSION SYSTEM
The high pressure fuel pump broke twice within a 6 month period. The first time, I was traveling at 70 mph in the middle of 100 degree weather in Texas. When I took it to the shop, the mechanic mentioned that the bolt broke inside of the engine and caused the high pressure fuel pump to break and dump gasoline everywhere. It was repaired by adding a new pump and fuel line. After driving it for 5 months, the same issue happened again while driving 30 mph. My safety was put at risk since it was large amounts of gasoline that it was throwing which could have easily caused a explosion/fire. The warning message was a check engine light and the truck going into limp mode. From my research, this exact issue was a recall for the 2018 version of the truck.
