What 2008 GMC Canyon owners say
Electrical system
Tl* the contact owns a 2008 GMC Canyon. While driving approximately 70 MPH, the contact noticed a burning odor. The air conditioner was on speed 2 as smoke and plastic particles emitted into the interior of the vehicle. While switching to speed 1, there was no response. There was also no response for speed 3. The air conditioner functioned at speed 4, but was later turned off due to the failure. The vehicle was driven to the contact's residence and parked due to the failure. The contact inspected the vehicle and noticed that the wiring harness and resister were completely melted. The vehicle was not inspected by a dealer. The contact replaced the wiring harness and the resister, and the air conditioner speeds 1 - 4 properly functioned. The contact was unable to determine if the parts would prematurely fail again. …
Been having an issue with the brake light switch at the brake pedal sticking and our brake lights staying on. We notice it mostly after we have parked the truck and turn it off. The brake lights will stay illuminated, not always right away. The brake lights staying illuminated have caused our vehicle to have a dead battery many times. This issue with the brake light switch causing the lights to stay on has actually caused us to have to buy 2 brand new batteries in just over a 12 month period. This issue has killed our battery and left us stranded for hours while waiting for someone to come help us jump the battery. There is a recall out for this brake light switch issue, but this specific year is not included in the recall. Even tho this truck is having the exact same issue the the recall is for. We have been dealing with this issue for over a year now.
Engine & cooling
When sitting at idle, the engine miss & spark knock at times. When start driving down the road the throttle seems hard to Press & takes a little time to reach up to road speed. The truck does not get good gas mileage at all. I had the spark plugs & wires changed still don't help.
Purchased vehicle new with 417 miles. From the beginning, there was a ticking noise at start-up, which gradually worsened to a loud knocking and vehicle shimmy for several seconds, sometimes requiring multiple attempts to start. Originally, it was only on cold start-up. Multiple visits to the dealer resulted in incorrect diagnoses or no diagnosis. Finally, at 18,071 miles, the problem was diagnosed as loose timing chain and worn gears. All were replaced by the dealer under warranty. Problem was significantly reduced but not solved. It then began to again worsen through multiple trips to the dealership, until 43,384 miles, when it was once more diagnosed as the timing having jumped or the chains having stretched. We declined to have the dealer replace everything with us paying for it, and had our own mechanic do the work. …

"cruise control" went out and I cannot find out where the problem is. The fuses are excellent. While I was driving I had the cruise control on, then all of a sudden for no reason the green illumination on the dash that let's me know it's on, was off. I tried to engage the cruise control again but that did not work. The green illumination on the dash does not come on anymore even as I attempt to engage the cruise control. I was on the highway at the time this happened.
