RAM Trucks 1500 — What to know
The RAM 1500 competes directly with the F-150 and Silverado and has broad independent workshop coverage. The HEMI 5.7L V8 has a cylinder deactivation system (MDS — Multi-Displacement System) with similar lifter failure risks as GM's AFM. EcoDiesel 3.0L models have had injector and emissions system concerns.
