When problems show up
No complaints for this year listed a mileage, so we can't say when problems show up.
Questions to ask the seller
- Any steering noise, wander or power-steering warning? Has the steering rack or pump been replaced?
- Do the brakes feel even, with no ABS or brake warning light? When were the pads and brake fluid last done?
- Any slipping, hard or late shifts, or a transmission warning light? Ask for transmission fluid service records.
- Infiniti sent dealers 51 repair notes for this car. Was this one done: “DRIVE SHAFT BOOT SERVICE INFORMATION SERVICE INFORMATION If a Drive Shaft (Axle Shaft) Boot on…”?
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 8 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.

In owners' words
steering feels loose and jumpy. dealer said it was mis-aligned, but that didnt fix the issue. car feels disconnected from road at times and making it hard to keep straight.

Every Infiniti Q50 year. 2023 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
