When problems show up
Most problems on this year showed up between 980 and 12,000 miles (1,600–20,000 km) (the middle half of the 101 complaints, of all 111 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? It has 8 recalls in all. Ask for the dealer printout, or check the VIN.
- Any steering noise, wander or power-steering warning? Has the steering rack or pump been replaced?
- Do all the lights, screens and power features work? Has the battery, alternator or any wiring been replaced?
- Is the airbag light off, and were any airbag recalls done?
- Infiniti sent dealers 256 repair notes for this car. Was this one done: “"Brake Judder" during braking, especially when braking at highway speeds”?
From this year's own recalls, top problems, top repair bills and Infiniti's repair notes. Recall repairs are free at any dealer.
How serious. Out of all 111 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 0K to 12K miles (2K to 20K km) on the car (101 of all 111 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
No steering, steering light in dash is lite and no steering, unable to drive vehicle.

Every Infiniti Q50 year. 2014 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.

Is the 2014 Infiniti Q50 reliable?
No, it is worse than average by government complaints. It drew about twice the average car's complaints filed with NHTSA in its first 3 years, per car sold (Lemon Index 182; 100 is average, lower is better). 2014 is one of the weaker years of a model that usually draws about three-quarters as many complaints as the average car. The Infiniti Q50 year with the fewest complaints per car sold is 2016.
What are the most common 2014 Infiniti Q50 problems?
In owner complaints to the government, the parts named most are steering (54%), electrical (23%) and airbags (13%). That is the share of complaints, not the share of cars that break.
How many recalls does the 2014 Infiniti Q50 have?
8 safety recalls (latest: transmission & drivetrain). Recall repairs are free at any dealer; check a specific car's VIN at nhtsa.gov/recalls.

Most problems on this year showed up between 980 and 12,000 miles (1,600–20,000 km) (the middle half of the 101 complaints, of all 111 filed so far, that listed a mileage). At 60K, 100K and 150K miles, a 2014 is 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 a prediction for one car.
Does the 2014 Infiniti Q50 have transmission problems?
Transmission and drivetrain issues aren't among its top 5 complaint areas.

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
