2019 Infiniti Q50 problems: engine and transmission complaints and recalls

HIGH COMPLAINT SIGNAL
52%
14 of 27 relevant owner complaints are about the engine, transmission or fuel system

52% of relevant owner complaints filed with NHTSA on the 2019 Infiniti Q50 are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.

Does the 2019 Infiniti Q50 have engine problems?

Owner complaints say yes, as a model-year pattern. 14 of 27 relevant complaints filed with NHTSA about the 2019 Infiniti Q50 concern the engine, transmission or fuel system (52%), and the largest group is filed under engine (10). For comparison, the 2018 scores 62%. 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.

Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.

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.

Should I buy a 2019 Infiniti Q50?

That depends on the car in front of you, not just the model year. The 2019 Infiniti Q50 has an elevated engine complaint pattern, so treat it as a car that needs proof: service records showing engine work, a cold-start test drive, and an independent pre-purchase inspection focused on the engine. A well-kept or already-repaired example can be a fine car; an unknown one is a gamble.
