2020 Jeep Grand Cherokee: engine and transmission complaints
HIGH COMPLAINT SIGNAL
42%
91 of 215 relevant owner complaints are about the engine, transmission or fuel system
42% of relevant owner complaints filed with NHTSA on the 2020 Jeep Grand Cherokee are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 51% of the 1,230 model years we track (2010–2023).
Excludes 21 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 39%).
Looking at a specific Grand Cherokee?Check its VIN: the full report, quotes about its own engine, and whether its recalls are still open. First report free.
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 2020 Jeep Grand Cherokee
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.
3 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.
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.
Experimental model-level information. This is not a vehicle inspection, vehicle-history
report, financial advice or purchase recommendation. It describes patterns across a model year, not the condition
of any individual vehicle. Combined across 3 body styles NHTSA files separately.
