How reliable is the Infiniti Q50? What NHTSA's records show
We don't give the Q50 a reliability score. NHTSA publishes complaint counts but no sales figures, so complaints can't be turned into a rate or compared between models. Here is what's on file for model years 2014 on.

Every model year compared
Complaints rise with how many were sold and how long they've been on the road, so a newer or rarer year will show fewer. Compare years of the Q50 with each other.

Common questions
Is the Infiniti Q50 reliable?
We don't score reliability: NHTSA publishes complaint counts but no sales figures, so complaints can't be turned into a rate or compared between models. What's on file for model years 2014 on: 488 owner complaints, 2 warranty extensions and 36 service campaigns Infiniti filed, and 11 safety recalls. The model years with the most complaints are 2014 (169), 2015 (126), 2017 (62). Whether a known problem was fixed on one car is what its service records show.
What are the most common problems with the Infiniti Q50?
Across every model year since 2014, owners' complaints to NHTSA most often name steering (25%), electrical system (18%), transmission and drivetrain (16%). Infiniti has filed 2 warranty extensions covering the Q50, listed on this page.
Which Q50 model years have the most complaints?
2014 (169), 2015 (126), 2017 (62). Complaint counts rise with how many were sold and how long they've been on the road, so compare years of the Q50 with each other rather than with other models.
Has Infiniti extended the warranty on the Q50?
Yes: engine (model years 2016–2018); engine and cooling (model years 2014–2017). A dealer does a covered repair for free within the extended time or mileage.
How do I check recalls on a Q50?
Enter the car's 17-character VIN at nhtsa.gov/recalls. That answers for one vehicle; the 11 recalls listed here are for the model, and each covers only part of it.
