Now has an oil leak at 40,000mi. Apparently very common on this model due to a poorly designed and shoddily constructed oil coolant lines. GM apparently not owning up to the problem. Not an expensive fix but a real reliability issue going forward. Wonder what other shortcuts might be lurking in this vehicle. Coolant leak at 50,000 mi. Needed a new radiator.

Beware the Chevy Lean, surprising that neither Edmunds nor Consumer Reports has addressed this issue! I purchased a 2017 Canyon in October of 2017 after a painful buying experience with the local dealer. I was looking at the Colorados and Canyons based on their high ratings from Edmunds and Consumer reports and that they were US made. The following morning I noticed the truck leaned significantly to the left, almost 1" when I measured it in my garage. I took it to the dealer who put it on a rack and measured it at 3/8" and said it was within GM spec.s and it was purely cosmetic. I had the dealer take it out on the concrete at the showroom and we measured it at 3/4", dealer said slab could be sloped so turned truck around and put in same place and got 3/4" again. They contacted GM who said they were working on a fix and opened a case file and I was told to wait for a fix. A couple of weeks later I found out on the internet that this has been ongoing on Chevys and GMCs to the extent it even has a name, "The Chevy Lean". Given the years it has been going on, I am wary if GM is indeed actually working on a fix since they haven't fixed it after all these years. I called GM and a Senior Customer Service Adviser called me back. She said she didn't know automotive lingo or technology(Just my luck) but had talked to the dealer who said it was within spec. Case closed! My advice is to stand back 30' or so and check before you sign and drive it home because once you do it's yours and could affect your resale!

Update 76,000 Miles: Motor failed. Had the oil changed (changed every 5k miles exceeding GM recommendation) and metal fragments found. Warranty expired at 60k and GM didn’t cover the bill as a result. Replaced the motor, traded it and got a new truck. Sad that a diesel motor doesn’t last more than 76k miles. Update 51,000 Miles: Still enjoy the truck but have what appears to be a common issue after some research, unable to get the key out of the ignition due to a faulty console shifter. Paid the $300 to have it replaced only to have it happen again 2 weeks later. So, my 2nd shifter is ordered and will be replaced under warranty. Overall, still a great little truck. I’ve had my 2017 GMC Canyon Diesel for almost 18 months and have almost 32,000 miles on it. Overall, I love the truck, the diesel, and the MPG. My only issues with the truck were the diesel emissions which was fixed under warranty, the driver side tail light moisture issue which was fixed under warranty and the dreaded left lean (1 inch) which was fixed under warranty. My biggest complaint is the low height for the front air dam which can’t even go over a parking curb. Why GM would do this with an “All Terrain” edition just doesn’t make any sense. I’m 6’1” tall and have plenty of room. The truck has plenty of power, rides nicely, and has good amenities. Overall, I’m very happy with my purchase for a daily driver with the option to actually haul a trailer or boat with no issues. Didn’t need the 2500HD like I had before so this is the perfect truck for me.

Fantastic Truck, 4 Cylinder diesel

After 34 years in either Toyota, Lexus or Land Rover products I ventured out to GMC due to the available diesel engine (fuel economy), easier entry, better towing and incredible cabin comfort. This truck is as quiet as any Lexus I've been in and great ride comfort. I'm not into serious off-road driving anymore so the lower entry height is great. There is only 1 inch difference in ground clearance between my GMC and the Tacoma but it's definitely easier to get into for my wife when she's wearing heels. As for the turbo diesel it's performance is as good as any gas engine in it's class but add the extra torque and now I can tow up to 7600lbs but what's really amazing is averaging over 30 miles per gallon on the highway and 24 or better combined highway/city. My previous Land Rover required premium fuel so the upcharge for diesel is a wash. I figured the extra fuel economy will pay back the additional cost of the diesel engine is about 2 years. In other words this is a quiet, nice truck with great fuel economy, incredible payload all in a midsize truck package that is easier to park than full-size and draws looks wherever it goes. I definitely enjoy the better seating arrangements as the Tacoma always felt like you were sitting just above the floor even with the power seats. Technology wise this truck is way ahead of the Toyota as 4wheel disc brakes are standard on the GMC and Tacoma is still using drum brakes on the rear and no 4wheel disc brake is available.

GM 8sp problems!!

After a few thousand miles of driving this new car , it had a transmission shutter due to the locking converter on the 8sp to cause the whole truck to shake, New fancy trans fluid, new locking converter and then new transmission did not help! GM customer care said I was not the only one, they had many complaints, but as to date have not done a fix/redesign. They use high performance fluid with metal flakes to try and help, but this is a lemon!!! Many times dealer will claim they can't repeat the issue , but all know GM has a big issue, they finally paid me off , so I could trade for another Non - GM Truck. Beware !!!!!!!
