There are 2 owner-reported fuel system complaints for the 2019 GMC Canyonin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.

Speed was rapidly reduced to 15 mph on the highway and started knocking hard. Mechanic found the pump physically broke and a bolt was sheered off inside of head.
