When problems show up
Most problems on this year showed up between 4,200 and 25,000 miles (6,800–40,000 km) (the middle half of the 33 complaints, of all 38 filed so far, that listed a mileage).
- At 60K, 100K and 150K miles (97K, 161K and 241K km) Past the range where most problems showed up: it has likely had them or dodged them, so repair records matter most.
This is when owners who had a problem reported it, not the odds that one car will have it.
Questions to ask the seller
- Were recalls 24V470000 (transmission & drivetrain), 16V430000 (steering) and 16V244000 (airbags) done? Ask for the dealer printout, or check the VIN.
- Do the brakes feel even, with no ABS or brake warning light? When were the pads and brake fluid last done?
- Is the airbag light off, and were any airbag recalls done?
- Any steering noise, wander or power-steering warning? Has the steering rack or pump been replaced?
- Infiniti sent dealers 204 repair notes for this car. Was this one done: “BRAKE NOISE/JUDDER/PEDAL FEEL DIAGNOSIS AND REPAIR This bulletin has been amended to include…”?

How serious. Out of all 38 owner complaints filed so far (every year since it was sold, not just the first 3), owners reported:
“Average car” = what the same number of complaints would include at the rate across every model year we track. Owners report these themselves; NHTSA doesn't confirm the cause.
What owners complain about most. From owner complaints to the government.
Share of this year's owner complaints filed with NHTSA, not the share of cars that break. One complaint can name more than one area.

When owners reported problems. From owner complaints to the government.
Most owners who filed a complaint with NHTSA had 4K to 24K miles (7K to 40K km) on the car (33 of all 38 complaints filed so far listed the miles). This shows when people who had a problem reported it, not the odds that your car will have it.
In owners' words
The vehicle is on a national do not sell list, this is awful for resale value!!!

Takata recall - passenger airbag. I've had this car for 9 months and I can't have passengers ride in it? Get me a loaner car then.
NHTSA complaint 10939979
Your form doesn't work for me. All systems were affected. I totaled my car while driving up a hill, in cruise control, and I hit a puddle. The car accelerated into the median. I was no longer a driver; I was a passenger.

Every Infiniti Q50 year. 2015 is highlighted. Lower is better.
Newest year first. Red = worse than average, gray = about average, too new (2023+: a partial score, marked “partial”) or too few complaints to score. #1, #2… = that year's YouTube rank among the 5 Infiniti Q50 years with enough videos (#1 = the year owners and reviewers talk about most positively). It is not a reliability rank.

The Lemon Index counts owner complaints filed with the U.S. government (NHTSA) in a car's first 3 years, per car sold, against the average car of the same model years (100 = average, lower is better). It measures complaints, not crash safety. A complaint is an owner's report, not a confirmed defect. How it works
