The main thing is I miss the V8 power, which is more a reflection of my personal choices than the quality of GMC trucks. I'd been wanting to jump down to a mid-size pickup since I don't do any real heavy hauling or towing, but the Canyon just feels underpowered in everyday use. The gearbox is sluggish, especially climbing hills, and braking is rather spongy... I get that it's a truck and not a sports car, but it wouldn't out-maneuver some of the much bigger trucks that I've had. Otherwise, a handful of little grievances, mostly around the interior. The backup cam keeps going offline, and I'm scheduled to bring it in so they can find the loose wire. The wireless charging platform, which admittedly is totally unnecessary, is too small to fit any modern cell phone. That's a real "what's the point?" moment. Gas mileage a bit worse than the estimated 16/22, combined with a small tank, means I'm filling up every 300 miles or so. That said, the ride is smooth, there's plenty of storage, and mechanically it hasn't skipped a beat in the first 6 months/8k miles.
