2019 Infiniti QX50 problems: engine and transmission complaints and recalls
68% of relevant owner complaints filed with NHTSA on the 2019 Infiniti QX50 are about the engine, transmission or fuel system. Well over half of everything owners reported is the drivetrain. That is a severe model-level pattern; every model year we track at this level has a documented failure behind it.
Worse than 89% of the 1,790 model years we track (2010–2023).
Does the 2019 Infiniti QX50 have engine problems?
Owner complaints say yes, heavily, as a model-year pattern. 94 of 140 relevant complaints filed with NHTSA about the 2019 Infiniti QX50 concern the engine, transmission or fuel system (68%), and the largest group is filed under engine (53). 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.

2019 Infiniti QX50 engine recalls
Yes. NHTSA lists 1 recall campaign on the 2019 Infiniti QX50 involving the engine, transmission or fuel system, out of 3 in total. A recall is the manufacturer admitting a defect and paying to fix it; whether a specific car still has one open depends on its VIN, which the full report checks. The owner complaints above are a separate record and often point at problems that never became a recall.
Nissan North America, Inc. (Nissan) is recalling certain 2021-2024 Rogue, 2019-2020 Altima, 2019-2022 Infiniti QX50, and 2022 Infiniti QX55 vehicles equipped with 3-cylinder 1.5L or 4-cylinder 2.0L variable compression turbo (VC-Turbo) engines.
