2012 Ram 2500 problems: engine and transmission complaints and recalls
ELEVATED COMPLAINT SIGNAL
35%
94 of 283 relevant owner complaints are about the engine, transmission or fuel system
35% of relevant owner complaints on the 2012 Ram 2500 are about the engine, transmission or fuel system. That is elevated. Worth an independent inspection before you commit to one.
Better than 62% of the 1,789 model years we track (2010–2023).
More than most. The pattern is elevated rather than severe. 94 of 283 relevant complaints filed with NHTSA about the 2012 Ram 2500 concern the engine, transmission or fuel system (35%), and the largest group is filed under engine (44). For comparison, the 2011 scores 20% and the 2013 scores 42%. On a test drive, check for stalling, loss of power, rough idle, oil consumption or a check-engine light. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.
The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.

This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.
Before you buy a 2012 Ram 2500
Ask the seller whether the engine has ever been repaired or replaced, and whether the car has shown stalling, loss of power, rough idle, oil consumption or a check-engine light.
Drive it from a cold start and long enough to warm up. Many engine faults hide once the car is warm.
Get an independent pre-purchase inspection from a mechanic you choose, and tell them to focus on the engine.
5 recall campaigns on this model year. Whether a specific car still has one open depends on the VIN; the report checks that.
Ask for service records. A engine already replaced under warranty is a different car from one that was not.

Should I buy a 2012 Ram 2500?
That depends on the car in front of you, not just the model year. The 2012 Ram 2500 has an elevated engine complaint pattern, so treat it as a car that needs proof: service records showing engine work, a cold-start test drive, and an independent pre-purchase inspection focused on the engine. A well-kept or already-repaired example can be a fine car; an unknown one is a gamble.
