Roller lifters on the Gen III 5.7 Hemi can wear or seize, flattening the matching camshaft lobe and sending metal debris through the engine. A lawsuit in Delaware federal court (Petro v. FCA US) covers 2014–2020 Ram 1500s and cites a 2017 Chrysler STAR case report on cam-lobe and lifter wear. In 2024 the judge dismissed the nationwide class claims but let fraud and implied-warranty claims proceed. There is no recall; the usual repair is new lifters and a camshaft.
Symptoms
- Ticking from the top of the engine that does not fade when warm
- Misfire codes or a flashing check-engine light
- Rough idle, surging or a chirp/knock
Check before buying
- Listen to a cold start and a warm idle for ticking
- Scan for stored misfire codes
- Ask for records of any lifter or camshaft replacement
