2015 Infiniti Q50 problems: engine and transmission complaints and recalls
44% of relevant owner complaints filed with NHTSA on the 2015 Infiniti Q50 are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.
Worse than 54% of the 1,790 model years we track (2010–2023).
Excludes 21 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 37%).
Does the 2015 Infiniti Q50 have transmission problems?
Owner complaints say yes, as a model-year pattern. 46 of 105 relevant complaints filed with NHTSA about the 2015 Infiniti Q50 concern the engine, transmission or fuel system (44%), and the largest group is filed under power train (39). For comparison, the 2014 scores 19% and the 2016 scores 45%. On a test drive, check for shuddering, slipping, delayed or harsh shifts, or a whine at speed. 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.

2015 Infiniti Q50 powertrain recalls
Yes. NHTSA lists 1 recall campaign on the 2015 Infiniti Q50 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. (INFINITI) is recalling certain 2011-2013 M56, 2012-2013 M35 Hybrid, 2014-2018 Q50, Q70 Hybrid, 2014-2019 Q70, and 2015-2019 Q70L two-wheel drive vehicles. The driveshaft can fatigue and break.

Fix: Dealers will replace the driveshaft, free of charge. Owner notification letters were mailed August 13, 2024. Owners may contact INFINITI's customer service at 1-800-662-6200. INFINITI's numbers for this recall are…
