The final, most-sorted fourth-generation Ram — the lowest complaint count of its generation, with a longer recall list to simply confirm as closed.

A 2018-specific recall covers a voltage-regulator chip in the powertrain control module that can fail and cause a stall or no-start; the remedy replaces the PCM free. Because a stall is a safety issue and the fix is straightforward, the only real task is confirming it was completed by VIN — but an unaddressed truck is worth pausing on. Ask for the recall record and scan for stored codes.

The Hemi's cross-generation valvetrain risk: a worn lifter and cam lobe tick and eventually misfire. Independent mechanics quote a cam-and-lifter job at a minimum around $4,500, with full engine replacement often recommended once metal shows in the oil. Cold-start and listen — a persistent tick is the walk-away sign on any Hemi. Pentastar V6 trucks avoid this specific risk.

Three 2018-era driveline recalls to confirm: an incomplete rear-driveshaft weld that can crack or fracture (19V324, 2018–2019), an incorrect transmission park-lock rod that may not hold the truck in park (18V280), and an underfilled rear differential that can fail or lock the rear wheels (18V556, 2018–2019). All are free fixes. Individually minor, collectively they mean the driveline recalls on a 2018 are worth a specific VIN check.

The ABS control-module failure that dominates 2016–2017 is present here too — confirm anti-lock brakes, cruise, and traction control all function. And if the truck is a 3.0L EcoDiesel, the EGR-cooler (19V757), crankshaft tone-wheel (20V475/23V411), and high-pressure-fuel-pump (22V406) recalls apply and should be confirmed closed. A 2018-specific backup-camera recall (18V398) and side-curtain airbag recalls (25V010, 25V592) round out the list.
