2018 INFINITI Q50
This model year
What the record shows
The 2018 Infiniti Q50 is a midsize car, and the 5th model year of a nameplate NHTSA records from 2014 to 2024.
The EPA rated two configurations: engines from 2-litre four-cylinder to 3-litre six-cylinder, rear-wheel drive only, a single transmission, Automatic (S7) and running on premium gasoline.
Combined fuel economy ranges from 23 to 25 mpg depending on which one you have.
The federal record holds 44 owner complaints, 3 safety recalls and 156 service bulletins for it.
Counts are reports, not rates. A complaint is something an owner chose to file; it is unverified and unadjusted for how many of these cars were sold, so the useful comparison is against other model years of the same car. Recalls and investigations carry more weight because a manufacturer or regulator acted on them.
Reading this report
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
