If you're shopping used Rams from 2019-2024, listen for the Hemi tick, that cold-start ticking noise signals lifter failure brewing, a repair that costs thousands and craters resale the moment it starts. Owners report oil pans corroding through at 55k miles, transmissions shuddering, and catastrophic engine failures on brand-new 2024s that didn't survive to their first oil change. One buyer found the parking brake held together with Vise-Grips. The 2025 redesign ditches the Hemi entirely for a Hurricane inline-six, and early expert reviews praise the smooth ride, strong power, and luxury-grade cabin in top trims. But it's too new to prove Stellantis fixed the underlying quality control issues or just swapped problems. Used Hemi-era trucks are a gamble unless you verify low idle hours and no tick. New buyers are beta-testing a clean-sheet powertrain from a company whose recent track record offers little reassurance. If you need a full-size truck now, the F-150 and Silverado have more predictable long-term costs.
You're buying a Cummins diesel wrapped in a truck that can't quite match the engine's legendary toughness. That powertrain, especially the older 5.9 12-valve or the new 2025+ ZF8 setup, will tow anything you hook to it and run past 300k miles without drama. Everything bolted around it tells a different story: ball joints that wear like brake pads, electrical gremlins that show up at 2,500 miles, brake calipers grenading before the first oil change. The 2025+ finally got the transmission right, but quality control is shockingly poor for a $70k truck. If you're towing heavy loads regularly, the Cummins is still the best tool available. If you're daily-driving it empty or expecting fit-and-finish that matches the price tag, prepare for disappointment. Buy it for the engine, budget for everything else breaking.
