Two problems related to automatic transmission torque converter have been reported for the 2016 GMC Canyon. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2016 GMC Canyon based on all problems reported for the 2016 Canyon.
Vehicle does not respond to acceleration command while entering a highway or during highway driving, increasing the risk of collation with other vehicles due to transmission failure, suspect the torque converter not working properly. This is a major and well known issue, gm continues to ignore and I do not want to become the next statistic dead in us highways. The vehicle is moving, during a red triangle yield sign entering the highway, the vehicle will not respond to acceleration command causing a bottle neck of traffic behind me and high risk of being rear ended. This is a serious defect affecting the transmission, it needs to be investigated and resolved as soon as possible.
Transmission hunts for gear when trying to accelerate 25-40 mph when transmission temp is 120 degrees and higher in slow and go driving. Leads to dangerous situation because accelerator pedal must be 'stomped' on to get transmission to downshift. Especially dangerous on wet roads when rear of truck can swerve when accelerating and in slow and go traffic having to push hard on accelerator to go when many cars around. Gm knows of the problem and publishes paper stating exactly the symptoms and and tell dealers not to take further action other than making software up to date which solves nothing. Not all gm trucks and even cars of this year are affected but years before and after for decades have this same issue as found on internet forums. Changing to different transmission fluids and even changing torque convertors has been done in the past but for 2015/2016 no remedy is offered. This has been going on 1. 5 years since new and getting worse. Because of lack of out of service days I don't think lemon law applies.
