FAQ About Dodge, Ram, Chrysler & Jeep Engines
What’s the most common Hemi problem?
- The Hemi tick — caused by lifter and cam wear. Left unchecked, it can damage the camshaft and engine.
Is the Jeep 3.6 Pentastar reliable?
- Yes, but Gen 1s (2011–2015) had issues with oil consumption and cylinder head failures. Gen 2+ is much improved.
Can the Hemi tick be fixed permanently?
- Yes — replacing lifters, camshaft, and related parts with updated designs resolves the issue long-term.
