1500buyer's guide

The eTorque mild-hybrid system on 2019–2021 Ram 1500s has known battery module failures that dealers often misdiagnose — repair bills can hit $2,000–$4,000 — and this guide gives you a checklist of warning signs to look for before you sign anything. The fault often shows up as rough idle or intermittent start-stop failure before the warning light appears.

This guide covers 14 documented faults: eTorque 48V battery module failure, 8-speed transmission shudder and hunting (a widespread issue on early builds), air suspension compressor failure (optional suspension), rear axle seal leak on eTorque models, electronic parking brake failure, HVAC blend door actuator failure, tailgate power release failure, uConnect infotainment freeze and reboot loop, fuel injector ticking on 5.7 Hemi at cold start, valve train noise on 3.6 Pentastar, hood insulator pad deterioration, body panel corrosion on pre-2021 builds in salt climates, windshield delamination, and power running board failure. Each includes a field check and real repair costs.

The 5th-gen 1500 is a genuinely impressive truck — but the eTorque system and 8-speed transmission are where most buyers get caught out on early examples. This guide tells you what to check.
