Fuel/Emissions: I have a 2017 GMC Canyon; I am not able to fuel the truck without the use of a funnel. As soon as I start fueling, it shuts off and "spits gas" on my clothes. When I do use the funnel, it takes me almost 20 minutes to fuel the truck. I have read in forums that it is a common occurrence with the 2017 Colorado and Canyons. I have tried to explain to the dealer that it may have a clogged evap canister. The dealership was dismissive and said it was a purge valve. The dealership changed the valve but failed to fix the issue. I returned to let them know and was told it would be days before anyone would look at the vehicle even though I did call and was told to bring it. Two things, evap canister is part of the emissions system and is to cut down on the emissions, and secondly, the gas gets everywhere when it "spits" it out because the vapers have no where to go. This is the only vehicle my wife and I have and is a good truck. There are plenty of forums such as coloradofans.com on line where others have the same issue.

I have a fuel leak coming from the top of the fuel tank and running down the side of the tank. The leak occurs when the vehicle is running so it's appears to be coming from the high pressure fuel line or top of the fuel pump. It appears to be exactly what is described in NHTSA Campaign Number 18V358000 and in GMC Recall 18188 however GMC Customer Support told me recall 18188 only applies to the 2018 year model and not my 2017. When I search for recalls on NHTSA by VIN it tells me 0 unrepaired Recalls. My wife and I both smelled gasoline Friday afternoon when we returned from a trip. We have not driven the vehicle since. I started the vehicle and let it idle in our driveway and after a couple of minutes fuel began to leak and run down the side of the gas tank.

Vehicle stalled when I was making a left turn onto route 23 from route 296 in windham NY. Car shuttered and stalled. Almost got T-boned by a semi. Extremely lucky that I was able to roll backwards onto the bridge behind me. I did go online and saw that were other owners with the duramax diesel that experienced similar problems. This could have been a fatal issue. I'm actually worried about driving this pick up. Contacted the dealer and they told me without the error code they couldn't help me. Disconnected the battery to clear the check engine light. Any suggestions?

Truck stalls as if in neutral after starting. Unfortunately, I have to let this truck run for T least 10 minutes or more before I can take off. If I start the truck and put it in drive any sooner, truck won't move. Actually, it runs then send to slam (very hard jerk) into drive, studders, then functions normal. I took it back to dealer and they say there has been multiple complaints about these trucks. I also was told GM put a statement out about these complaints and said there is nothing they can do to fix, in so many words. Dealer say it will go away. I've had this vehicle since July 4 2019 and still happening almost everyday.

2017 GMC Canyon equipped with diesel engine will sporadically shut-off while operating when driving with a tank that is less than 1/4 full. On 1/31/19 (odometer ~14200 miles) vehicle was driving fine with an ambient air temperature of roughly 0F, fuel tank at 1/3, when all of sudden the engine died in traffic with no warning. Vehicle then needed to be towed to the dealership for service at which point they couldn't find anything wrong with it. Again on 3/4/19 (odometer ~15100 miles) vehicle was driving fine when the dash lit up with multiple codes and truck went into reduced power mode, ambient air temperature 10F gas tank at 1/8th. Got out of truck and it smelled like it was on fire. Called to have vehicle towed to dealership. Vehicle kept for multiple days at dealership, dealer worked with GM to identify an issue and no fix was found. Dealer called to instruct me to not drive the vehicle with less than 1/4 tank during winter and also mentioned that this has been an issue with a few other Canyon and terrain diesel models. GM needs to find a fix for this! it is totally unsafe and unacceptable to have a truck that will unexpectedly loose total power when driving due to a design flaw in their systems.
