2021 Acura RDX: engine and transmission complaints
NO ELEVATED SIGNAL
30%
29 of 96 relevant owner complaints are about the engine, transmission or fuel system
No elevated drivetrain complaint concentration in the available NHTSA records for the 2021 Acura RDX. Engine, transmission and fuel system account for 30% of relevant complaints.
Better than 69% of the 1,230 model years we track (2010–2023).
Excludes 15 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 26%).
Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.

This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.
Before you buy a 2021 Acura RDX
No elevated drivetrain pattern for this model year. That describes the model, not the car in front of you.
Get an independent pre-purchase inspection from a mechanic you choose.
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.
