Transmission Not Engage Problems of GMC Canyon

When attempting to turn left onto a highway from a stop sign, the transmission failed to engage, with a 2-second delay before engaging and accelerating into the turn. As a result of the delay, I was nearly hit by oncoming traffic. This vehicle model, 2016 GMC Canyon, has a history of not being in the proper gear when stopped or moving at speeds below 3-5 mph. This issue has happened to me over 100 times in the first 6 months of ownership, but this was the first time I nearly had a dangerous collision. GMC should correct this problem with the transmission not being in the proper gear for being stopped or for extremely low speeds.

Vehicle shifting lags and hesitates then engages abruptly causing unsafe acceleration. Specifically entering an on-ramp. When trying to merge into traffic from a slower ramp speed to join highway speeds the vehicle struggles to find the proper gear. In order to offset this problem the driver needs to depress the accelerator further to help the transmission downshift to a lower gear. However, doing so while the transmission is searching for the proper gear causes the vehicle to suddenly lurch forward with more force and acceleration then is required or safe. I have brought my truck into the dealership twice for this issue and was told that gm states that this is the normal operating conditions of the truck. I feel this is not an adequate response and certainly does nothing to address the safety issue of a transmission that disengages to search for a proper gear and then reengages abruptly causing the driver to make unnecessary and unsafe adjustments to keep the vehicle under control.
