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 has a bad shudder where it is causing drivability issues. This occurs mainly when driving up an incline when at about 1200 RPM. Truck will sometimes jerk and shake and has poor throttle response causing dangerous driving conditions. This has happened several times over the coarse of about 3 months with the last instance occurring today.

Transmission started shuddering very badly when taking off from a stop sign under wet conditions. This occurred when throttle was reduced after the rear wheels broke traction. Gm knows about the transmission issues and the dealership has refused to repair it.

Vehicle upshifts too early at low speeds requiring additional accelerator input then downshifts 2 gears to compensate. This happens regularly when going around 15-20 miles an hour uphill or while making right turns while vehicle is in motion. When the vehicle is searching for the correct gear the accelerator pedal is numb for at least 2 seconds requiring at least 90 percent throttle then it finally picks a low gear and violently throws the driver and passengers back and roars to life. The 2 or more seconds of hesitation could be very dangerous in an emergency situation when quick acceleration is needed. My concerns were voiced to bowser buick gmc on 11/20/2015 during my first oil change and they provided me with service bulletin #pip5342 which states "shudder or chuggle when accelerating at low speeds of 12-15 MPH in second gear is normal operation of the automatic transmission and the torque converter clutch. No repair attempts should be attempted to address this concern" they refused to make any repairs and said that I was added to a list of others with similar complaints.
