In Dec 2018 I bought a 2018 Canyon SLT. A few months later i started hearing a squeak coming from under the truck. After going to 2 dealers, they could not solve it. It sounded like rusty bed springs when going over bumps. Today i got underneath the truck. The parking brake cables located just under the drivers side rear door were rubbing against a steel bracket. I moved them a little and wrapped them with duct tape. No more squeak. Amazing. The second dealer wanted to replace the leaf spring mounts. I hope this helps.
