1) <powertrain> I have 40k on my Canyon and am experiencing acceleration issues 0-40mph 1-3rd shift points (automatic transmission). The transmission acts like it cannot decide to either say in 2nd or shift to 3rd and there's a lag or surging affect when this happens. I had the transmission fluid and transfer case fluids changed ar the gm dealership. Problem still persists. 2) <other> key gets stuck in the ignition. When placing the truck in park there's an internal relay/switch within the shifter that is supposed to activate a relay/unlock signal to the key tumbler in the steering column. This doesn't always happen and the key won't turn to the off position to allow it to be released. I have to turn the key to the acc position put the truck in drive then back into park to get the relay/switch to dis-engage the key position from being locked in acc.
