Re: 2012 Jeep GC 3.6L notorious problem

Probably wont happen again. As i understand it the problem was a run of bad heads that are covered under warranty. I would think that most of them have been replaced by now since this was early in the production cycle of 2012s IIRC.

Did you have a date range of the builds with the bad batch of heads? Perhaps a range of VIN?

Mines at 34,000 km and I've still got 3.5yrs left of warranty. I do average 25, 000 km per year. My 2012 is a july build.

Re: 2012 Jeep GC 3.6L notorious problem

No but usually in the 15-25k mile range. I suspect it was a machining misalignment of valve guides but have never seen a real answer or range of serial numbers.

Is part of the reason I bought a lifetime service contract since I may not get to even 15k this year.

Might mention that it is very nearly the perfect vehicle for my needs and I like it better now than when I bought it in Jan '12. Have decided to sell my Vixen RV and buy a trailer instead.
