Check a VINDoes the 2021 Infiniti QX50 have engine problems?
Owner complaints say yes, heavily, as a model-year pattern. 27 of 40 relevant complaints filed with NHTSA about the 2021 Infiniti QX50 concern the engine, transmission or fuel system (69%), and the largest group is filed under engine (18). For comparison, the 2020 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.

Recall campaigns on the 2021 Infiniti QX50 (2)
This does not say whether a particular car has an open, unrepaired recall. That depends on the VIN.
Before you buy a 2021 Infiniti QX50
- 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.
- 2 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.
