Nice summary of the evolution of the Pentastar engine and problems reported

[Dave2018]

This is a nice summary of the Pentastar, it's history, issues, and updates.

"In general, the engine has been around for a long time and used in a lot of vehicles, so it has been well tested. Despite that they had some issues early on, the 3.6L V6 Pentastar is a great engine, one of the most reliable engines available on the market right now. "

I had a 2012 Jeep I traded in on my 2020 1500 Classic. It had a head issue early on that was replaced under warranty. When I traded it in with 48k miles it was just getting broken in. Was getting better gas mileage the more miles I had on it. I am guessing 8 years later a lot of the bugs have been worked out.
