Ask Any Jeeper: These Are the Engines You Can Count On

7. 3.6L Pentastar V6

This is the engine modern Jeeps grew up with. From 2012 on, the Pentastar V6 became the go-to. It’s got up to 305 hp, solid efficiency, and a much-needed upgrade from the sad old 3.8L.

While some early models had rocker issues or sand casting debris, most Pentastars run smooth and trouble-free. Timing chain instead of a belt, lots of aftermarket support, and no weird maintenance demands. It’s a smart pick for most buyers.
