2nd owner here. 2017 CCLB 4wd. Had 22,000 miles on it when I picked it up. Now over 50,000. Only had one issue with reduced power when I first got it and dealer fixed it. No issues since. Recently installed Zone 6” lift and 305/55R20s. Now it shifts a little hard and occasional torque converter shudder. Programmer from Shield and Spear on the way should solve those issues.
