2020 Acura TLX problems: engine and transmission complaints and recalls
HIGH COMPLAINT SIGNAL
55%
33 of 60 relevant owner complaints are about the engine, transmission or fuel system
55% of relevant owner complaints filed with NHTSA on the 2020 Acura TLX are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 73% of the 1,789 model years we track (2010–2023).
Excludes 3 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 52%).
Owner complaints say yes, as a model-year pattern. 33 of 60 relevant complaints filed with NHTSA about the 2020 Acura TLX concern the engine, transmission or fuel system (55%), and the largest group is filed under engine (19). For comparison, the 2019 scores 63% and the 2021 scores 70%. 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 2020 Acura TLX
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.

A well-kept or already-repaired example can be a fine car; an unknown one is a gamble.
