2017 GMC Canyon Fuel system Problems

“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. …”

“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. …”

“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 had 4 loads of mulch loaded in my 2017 Gmc Canyon in early june 2019. Some mulch fell between the cab and cargo box where it smoldered on top of the truck gas tank for weeks until it melted tubes prompting onstar to send me two emails 6-27-19 and 6-29-19 to see my Gmc dealer within 7 days for an issue with the emission system . The dealer ignored my first visit and may have ignored the second but now the vehicle would not allow me to pump gasoline due to a melted tube and other parts on top of the fuel tank. …”
