2015 GMC Canyon: engine stalls while driving

Filed Dec 17, 2025 · Fuel system · FL

I own a 2015 GMC Canyon that developed repeated and serious fuel-system and engine problems beginning around 56,000 miles. The vehicle experienced fuel contamination (water in the fuel system), multiple fuel injectors failing and sticking open, repeated misfires across several cylinders, and engine stalling/shutdown while driving. The truck was towed multiple times and repaired repeatedly by an authorized GMC dealership. Repairs included injector replacements, fuel pipe replacement, fuel-system cleaning, and related work. Technician notes show that broader repairs were recommended but not fully authorized, and the same problems continued to return. Despite the dealership later stating the vehicle was repaired, there is no written safety certification, no documented fuel-system integrity testing, and no GM engineering clearance confirming the vehicle is safe to operate. Because of the repeated failures and risk of fire or loss of power, I do not feel the vehicle is safe to drive. I personally paid over $6,000 out of pocket for fuel contamination repairs and spark plug replacement (not including towing), after warranty coverage denied some repairs as “water damage.” The vehicle has been unsafe or inoperable for extended periods. I am reporting this because repeated fuel-system failures and engine shutdown present a serious safety risk and may affect other vehicles of the same model.

Several times in the past 2 years, my 2015 gmc canyon has stalled when either coming to a stop or trying to start from a stop. Most times it shudders while stopping then the engine shuts down. 2 times I thought that I was safe from stall because it remained running after the shudder but when I stepped on the gas to go it stalled. The last time, about a week ago, it happened while trying to cross a busy intersection. Causing me to panic, throw it into neutral and start, with barely enough time to throw it into gear and get out of the way of oncoming traffic. It's scary and dangerous to both me and to other drivers. Ive attempted to take it to the dealer but they won't do anything because there aren't any warning lights on. I did get a notice on this, took it back into the dealer and again was told without warning lights they won't do anything. So does someone actually have to die or be in a life changing accident for something to be done?

Vehicle stalls then jerks forward when accelerating and decelerating. Jerking causes brief loss of control as vehicle lurches forward while transmission attempts to catch up. This occurs at any moment while driving (uphill, downhill, turning, city streets and highways) seems to occur most when speeds are under 60 MPH. Causes very unsafe conditions and check engine light goes on and off. Occurred today and has occurred almost everyday since I've owned the vehicle. (2 years)

Tl* the contact owns a 2015 gmc canyon. The contact stated that the engine stalled numerous times while idling at a complete stop. The vehicle was taken to todd wenzel buick gmc of davison (1146 south state road, davison, michigan, (810) 655-9587) for diagnostic testing, but the dealer was unable to locate a failure code. The dealer also test drove the vehicle and was unable to duplicate the failure. The manufacturer was made aware of the failure. The vehicle was not repaired. The approximate failure mileage was 31,000.

While driving at a steady speed, when attempting to lightly or moderately accelerate, a lack of power is noticed due to torque converter lockup. Engine comes close to stalling out. In may 2016, I was informed gm engineering was aware of the problem were working on a solution. During a followup visit in september 2016, I was informed that gm no longer considered it a problem and were no longer working on a solution. Gm tac # 8-2110571583. There has not been a specific accident related to a lack of acceleration when expecting to accelerate, there remains the potential especially when merging into freeway traffic during peak travel times. The gm district service mgr drove the truck and informed me that there was no issue as he drove the same vehicle type and had the same performance. Per recent gm marketing, the 2017 gmc canyon features a completely re-designed transmission. I believe this issue with the transmission is a safety issue caused by a poorly designed transmission.

On cold starts, the engine will stall at first stop. Typically this is at the first stop light or stop sign in the morning on the way to work. This is beginning to happen several times a week. It also has happened after sitting for several hours. It only appears to happen when starting the truck after the engine has cooled. Prior to stalling, the engine will hesitate and the rpms drop until ultimately stalling. I have called the gmc number and have asked the dealership to check it out. It cannot be duplicated by them and they say gm has not issued a recall or bulletin to repair.
