2018 Infiniti Q50
This year drew an ordinary 42 complaints for a Infiniti Q50 — the model's median is 30. What they were about is the unusual part: 14.3% of them mention noise, against 4% across the model's other years.
Generation 1 of the Infiniti Q50, which began in 2014. Everything below compares this year against the others in that generation, not against a different car wearing the same name.
NHTSA opened a defect investigation into this model year.

What the complaints were about
- noise — 14.3% of this year's complaints, against 4% across the model's other years (3.6×). Owners wrote it as: noise, consistent, warm-up, whoreling.
- way — 14.3% of this year's complaints, against 5.3% across the model's other years (2.7×).
- phone — 9.5% of this year's complaints, against 3.2% across the model's other years (3×). Owners wrote it as: phone, call.
Words owners used for the same problem are counted together, so a fault written four different ways is measured once. Grouped by which complaints they appear in, not by a list anyone wrote in advance.
What owners wrote
FROM START INTO THE WARM-UP, THERE IS A CONSISTENT WHORELING NOISE COMING FROM THE MOTOR.
THE SERPENTINE BELT MAKES CONSISTENT NOISE IN ALL TYPES OF WEATHER. ALREADY HAD THE DEALER REPLACE IT ONCE. NOISE CAME BACK AND THE DEALER NOW SAYS IT COULD BE THE TENSIONER PULLEY.

How this was worked out
Every year of the Infiniti Q50 was compared against its own history rather than against other cars, which removes popularity and age from the answer — a common car draws more complaints at equal reliability, and an older one has had longer to accumulate them. A year is flagged when it drew at least 2.5× this model's median and at least 50 complaints.
This is a fault record, not a review. Nobody files a federal complaint to say the car was fine, so it shows what tends to go wrong — not whether owners liked it, and not whether it is a good car.
