Update on the Canyon. Still going strong. No real issues to speak of. I thought I had an annoying rattle on the rear sliding window pop up but it turned out the gaskets on the tri-fold tonneau cover compressed enough over time to allow it to shift slightly and one of the plastic clips was tapping on the back window. That was a 5 minute fix to loosen it up, reposition it and re-tighten.
Fuel economy was pretty abysmal over the winter. To the point where I wonder if a V8 full size would have done any worse. A lot of it had to do with the fact that I am still working from home so with no commute, most of my trips are short and the engine barely had time to get warm. Still, I think I had one tank come in at 14.9 mpg. That was a bit of an outlier and most were in the high 15's or low 16's. Now that it is warm, it is generally averaging low to mid 17's and any longer trips I have taken with it have been more in the 21-22 mpg range.
It still annoys the crap out of me that a Denali does not have a Homelink garage door opener built in. I also continued to be annoyed by actually having to get the keys out of my pocket to unlock the doors and start it. I know that may sound ridiculous but once you have a number of cars in a row that have passive entry and push button start, its annoying to live with out. Call me spoiled. haha
I do wonder if I would have been better off with a full size truck. What appealed to me most about the Canyon (its size) is also my biggest problem with it. The front seats are fine but my long legged son is not too comfortable in the back seat. We also have a dog we take with us on our camping trips and it doesn't work very well for her. She's a bit of a nervous traveler so the floor is the best spot for her but there is no room there in the truck so she has to sit on someone's lap. That said, while those areas would be better in a full size, I know my wife would hate parking one. I also know since it stays parked in the driveway, I would have had to make my driveway a little wider to make it easier to get the other vehicles in and out of the garage and while I would have liked the interior room in the full size much better, the Canyon overall just fits us better.
