Have you guys seen the massive EGR cooler recall that is coming out right nowish? The valving inside is sticking which is dumping high temp exhaust gas into the intake manifold causing them to melt and in more and more cases is starting fires. I don't think it's officially a recall yet. Sounds like mid December. I'm not sure if the JL will be included. I do know that right now FCA doesn't have a fix so that either means they can't make the Gen 3 EGRs work on the older stuff or the Gen 3 uses the same EGR and will need to be replaced as well.
My original EGR failed a year ago and I believe the replacement is now leaking as well. These trucks are turning into a nightmare for a lot of owners. I hear resale is either dropping off the charts, or now a lot of places wont even trade them in do to the recall with no fix in sight yet. On top of that, the AEM emission retune that most are getting done is killing drivability. I got my AEM done and then purchased an aftermarket tune to fix what they messed up. That tuner, GDE, just got shut down by the EPA so those tunes are no longer available.
As much as I still love my truck (only thanks to GDE) no way would I buy another Ecodiesel, at least until this new Gen 3 becomes proven. The Gen 2 was said to be the fix for all the Gen 1 issues, but that proved false, for the most part.
