Owned this 2017 GMC Canyon for 1 year and 1 month with 5000 miles when it developed an oil leak. Brought to dealer who found the oil leak coming from a "pinhole" in the oil coolant hose. When I researched this specific oil leak online a found a forum post with many other people who have had this same issue since the 2015 model year. Other people did not notice the leak until all of their oil had drained and had to be towed to service. I noticed it early enough that I still had oil when I arrived at the dealership to get it checked out. It looks like this is still an ongoing issue with the 2018 models too, but not much is being done by gm to proactively fix the bad hoses.
