Engine started idling rough and then the check engine light came on. I took it to the dealer and they hooked the computer up to it and said #5 cylinder was misfiring and I needed a new engine.
My 2017 Jeep Grand Cherokee needs to have the head gasket replaced and water pump. It is under 60,000 miles (59,400) but 5 1/2 years old. Jeep is not honoring the warrantee since it is over 5 years old. This is a very expensive repair. Any thoughts or advice? Is this common problem with Jeeps? Should I get rid of car? I’m wondering if more problems will appear.The problem goes back in WK2s in the 5.7L Hemi to model year 2011 with the use of valve train multi-displacement systems. Needed a replacement engine in mine a bit over a year ago.

It’s stalling out and throwing a PO339 code and the sensors have been replaced three times.
