FWIW......My WK2 Jeep GC was first model year (2014 but bought in 2013) for WK2's. Even though JCG's have been around for decades the issues I had were documented on thread here:
https://expeditionportal.com/forum/threads/wk2-reliability.198401/
I stopped updating list in 2018 but since then have had big repairs including "multiple damaged camshaft lobes in right bank due to Rocker Arm failure" - they replaced both Intake & Exhaust Camshafts and 12 Rocker Arms & 12 Tappets in right bank - this was at 231,355 miles. Had I not had the Lifetime Warranty, I would have paid thousands for this repair alone. Even though it is high milage and stuff breaks, my long list of repairs has made me a bit sensitive.
I currently have 243,000 miles and still have open recall but everything seems dialed in. Truthfully, had I not spent $2,400 on the lifetime warranty I would be majorly p**sed and probably never buy again. I would not buy a 1 or 2nd year model without Lifetime Warranty.
