Just got my wife's 2018 Canyon back from the dealer for squeaking issue. Every time we pulled out/in of driveways, went over little bumps, we'd hear squeaking and chirping from the rear. At first the service rep said his suspension tech of 27 years was not able to recreate the issue and everything is fine. Called bs and went in to take it on a ride with the maintenance director and sure enough the squeaking was there. Later on they called us back and said they fixed the issue. Turns out there is a bulletin for this exact issue.

PIT5635B: Squeak/rattle noise from rear of vehicle over bumps thought to be from rear leaf springs
Cause: rear brake pads shifting
Correction: apply anti squeak compound/grease to rear pads
Affects: 2015-2020 Canyon/Colorado

missing phrase in the TSB... "like we should have done in the first place but the accountants figured that we could make 15 cents more per unit by omitting it" :p
