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.
All my dash lights keep coming on and alarms going off. the poer steering, abs, check engine, stability track, parking brake, brake, etc. if i pulled over and turned the vehicle off to get this to stop nothing works when i crank it up. i have no power steering. if i crank it a couple times everything goes to working. then a few miles it all starts again. this has been going on since april. i have put it in shop in april, the dealer couldn't get it to duplicate, in may, same thing, in june they finally got it to duplicate and changed a module. i drove it 772 miles it started again. i carried it back in july they said gmc said it was a steering gear. i got it back at 336 miles it started again aug. 2nd, it did it again at 798, then 813 miles on 8/9. i carried it back they supposedly found a rubbed spot in a wiring harness and fixed that stating they believe it is fixed. i contacted gmc in july trying to get them to take this truck back, they said they couldn't do that but extended the mfg warranty out to 100000 miles. i bought the truck used with 16000 miles on it still under mfg warranty, all the problems started at a little over 34500 miles. i fear for my safety as well as other due to steering wheel locking up. i mentioned this to gmc as well. is there anything i can do to get gmc to take this vehicle back? i can get paperwork from dealer if needed. is there anything you can do with this? i had a case # with gmc when the gave extended mfg warranty [xxx]. i talked with a representative name martin phone # 866-790-5700. ext. 5915657. i left him a message on 8/12, he is yet to return my call. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tt

After starting my truck and driving until the engine warms up, i turn on just the fan and the a/c light comes on. according to the manual that is only supposed to happen if the auto defog is activated. it does not turn on when i start the truck if the engine is warm. also, the radio/usb port will randomly turn on by itself when i start the truck or sometimes after i end a phone call. once the entire touch screen system was completely inoperable. i then could not turn the radio volume up or down, change stations, or use any features of the touch screen.
