2012 Jeep Wrangler: engine and transmission complaints
VERY HIGH COMPLAINT SIGNAL
67%
458 of 686 relevant owner complaints are about the engine, transmission or fuel system
67% of relevant owner complaints filed with NHTSA on the 2012 Jeep Wrangler are about the engine, transmission or fuel system. Well over half of everything owners reported is the drivetrain. That is a severe model-level pattern; every model year we track at this level has a documented failure behind it.
Worse than 88% of the 1,230 model years we track (2010–2023).
Excludes 147 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 55%).
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.
WHILE TURNING TO PARK THE ENGINE THROTTLE SUDDENLY ACCELERATED & JEEP JUMPED THE CURB, CRASHED THRU A FENCE & ENDED UP IN THE OCEAN. WE WERE RESCUED BY DANA POINT HARBOR PATROL.

I was driving on the highway and the engine caught fire. I’ve been looking for an engine to rebuild and all of them had previously been on fire. I believe the engine is defective for the jeeps that year, make and model.

This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.
Before you buy a 2012 Jeep Wrangler
Ask the seller whether the transmission has ever been repaired or replaced, and whether the car has shown shuddering, slipping, delayed or harsh shifts, or a whine at speed.
Drive it from a cold start and long enough to warm up. Many transmission 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 transmission.
10 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 transmission already replaced under warranty is a different car from one that was not.
Have the VIN?Paste it and get the full report for that car. First report free, then a 30-day pass covers a whole car search.
