Purchase my truck new 2022 with V-6 Pentastar engine and everything was great till the other day. Truck has 15,400 mile during hard acceleration entering expressway the trucks check engine light started to flash and engine felt like it was misfiring. Anyway the unit is still under warranty from factory so off to the dealer we went for problem. After it was done the right intake cam, six rockers and lifter were replaced. I had thought this problem was corrected with earlier Gens but I guess not . I am concerned what the future will bring when the warranty expires . Just thought I share my luck.
