Problem sheets

No single problem on the 2015 Infiniti Q50 has enough owner reports for a sheet of its own yet. The counts below still cover every complaint on file.

Is the 2015 Infiniti Q50 reliable?

The 2015 Infiniti Q50 has 126 owner complaints on file with NHTSA, less than half the median of 270 for 2015 sedans on this site. Of the 6 Q50 model years since 2014, it has the most complaints. Complaint counts rise with sales as well as faults, so read what owners report below before deciding.

At a glance

Next to other model years
Complaints filed before 2015 aren't in the files this site reads, so the 2015 count runs short and isn't compared with the model years next to it.
Top problem
No problem dominates. The largest, airbag, covers 19 of the 126 complaints (15%), and brake wear is next with 12 (one complaint can fall under more than one problem, so these overlap). A quarter of the 12 owners who gave a mileage for airbag saw it by about 21,000 miles, and half by about 29,000.
Crash, fire and injury reports
18 of the 126 complaints (14%) report a crash, a fire or an injury. The typical vehicle on this site sits at 6%, so this one runs well above it. Counted separately (one report can carry more than one), 16 reports mention a crash, 2 mention a fire and 10 people were hurt. The most crash reports, 9 of 16, fall under airbag.
Recalls behind the top problems
3 recalls are on file, but no problem here has enough reports to set against them.
When owners filed
Filings peaked in 2024 at 18 (full calendar years only). In 2025 there were 16. So far in 2026, 10 more have come in. Filings on record start in 2015.

When each problem shows up

        How this compares

        2015 Infiniti Q50126
        Median 2015 model here (104 vehicles)277
        Median 2015 sedan here (31)270

        126 complaints is 2.2 times fewer than the median 2015 model on this site and 2.1 times fewer than the median 2015 sedan. Among the 2 Q50 model years here it ranks 1st for complaints. Counts follow sales volume as much as reliability, so a truck that sells 700,000 a year draws more reports than a sedan that sells 200,000.

        Service bulletins for the 2015 Infiniti Q50
