OP: would still be nice to know which engine you have in your Rebel in your signature for easy reference. You can get different engines both gas & diesel in the Rebel as all other trims.
Call other Ram dealers around you & inquire. Read reviews on them. They might have useful warranty info. That’s why I ordered through my new dealer. They basically fix everything, nearly no questions asked due to who they use for warranty which is a company called CNA. Better warranty, cheaper or the same as Mopar depending on which package you prefer, & their approval ratings sound far superior to Mopar. The windshield company that repaired mine upon trade in purchases their Chrysler vans & Ram trucks at this dealer & they have replaced engines past 300,000 miles & repaired other items that weren’t even covered in the warranty. Not sure how they pull the paperwork off for approval, but also don’t care as long as they help out.
Yes 5.7, I thought posting in the 5.7 V8 forum would answer that. I don't recall the diesel or v6 available in 2019 in th Rebel ? anyways, this dealer (I didn't get the truck from here) has ALWAYS been good with my JEeps, and have sponsored my jeep club for years as well., never really had any issues and their techs seem quite knowledgable . The info I am getting is FCA keeps asking them to do more work, maybe it's all smoke and mirrors, but why keep having the mechanics do more work , that's costing the dealership $$$, only to possibly deny my claim for an air filter. Who is to to say the head gaskets WASNT leaking internally and collant caused excessive wear in the oil, I don't know.
