The best Infiniti Q50 model years are 2018 through 2024, which benefit from a mature platform, updated technology, and very low complaint volumes. We recommend avoiding the 2014 model year due to severe steering system defects and multiple safety recalls.
Rankings are comparative, meaning no used luxury sports sedan is entirely flawless. Maintenance history, previous ownership, and current vehicle condition always play a massive role in long-term reliability and ownership satisfaction.
Significant differences exist between early models with the naturally aspirated V6 and later versions featuring the twin-turbo V6. The steer-by-wire steering system also requires careful inspection on early production years.

How We Evaluated the Infiniti Q50 Model Years
Our analysis reviews official NHTSA recalls, manufacturer service campaigns, and consumer complaint databases. We weigh the severity and repair complexity of reported issues against the vehicle’s age and mileage.
Complaints are not confirmed failure rates, and a single recall does not automatically ruin a model year’s reputation. Recent models naturally have fewer complaints due to limited road exposure, while older vehicles require careful maintenance verification.
Best Infiniti Q50 Years
2018-2021: Best Choice
The 2018 model year introduced a significant mid-cycle refresh that updated the exterior styling and improved the interior infotainment system. By this time, the 3.0L twin-turbo V6 was well-sorted, and early steer-by-wire software bugs were largely resolved.
These years consistently show very low complaint volumes across major automotive databases. Buyers get a modern luxury sedan with strong performance and a comparatively favorable reliability record.
2022-2024: Best Late-Generation Choice
As the final production years before the Q50 was discontinued in the United States, these models feature the most refined version of the platform. Infiniti standardized more safety and convenience features across the lineup.
Because these vehicles are newer, long-term high-mileage data remains limited. However, they represent the safest contemporary choice for buyers wanting the latest available technology and remaining factory warranty coverage.
2016-2017: Good With Inspection
These years mark the transition from the older 3.7L V6 to the new 3.0L twin-turbo V6 and the brief availability of a 2.0L turbocharged four-cylinder. Performance improved noticeably, but first-year powertrain swaps always carry slight teething risks.
Certain 2.0L models were subject to fuel pump recalls. Buyers should verify that all software updates and recall repairs were completed by an authorized dealer before purchasing.
Best Year by Buyer Type
- Best Overall: 2019 Infiniti Q50. It sits comfortably in the post-refresh era with a fully sorted twin-turbo V6 and excellent infotainment integration.
- Best Enthusiast Choice: 2017-2019 Red Sport 400. This high-output trim delivers 400 horsepower and sport-tuned suspension, provided maintenance records are thorough.
- Best Budget Option: 2016 Infiniti Q50 3.0t. It offers the newer twin-turbo engine at a lower price point, assuming the fuel system recalls are addressed.
Years to Approach Carefully
2015: Approach Carefully
The 2015 model year avoided the worst of the 2014 steering recalls but still suffered from lingering electrical gremlins and early Direct Adaptive Steering complaints. The infotainment system also drew frequent criticism for being sluggish.
If you consider a 2015 model, ensure the steering system has received all mandatory software updates. A thorough pre-purchase inspection is necessary to rule out premature brake wear and suspension issues.
Worst Infiniti Q50 Years
2014: Avoid
The inaugural 2014 model year is the most problematic in the Q50’s history. The most severe issue involves the Direct Adaptive Steering system, which experienced sudden failures and erratic behavior, prompting multiple safety recalls.
Additionally, owners reported frequent issues with warped brake rotors and premature pad wear. The combination of critical safety recalls and expensive brake repairs makes this year a financial and safety risk for used buyers.
Infiniti Q50 Reliability by Generation
First Generation (2014-2024)
The Q50 rode on a single generation for its entire US production run, though it received a major refresh for 2018. Early years (2014-2015) struggled with the introduction of complex steer-by-wire technology and hybrid powertrain software.
The 2016 powertrain swap to the VR30DDTT twin-turbo V6 improved performance but required a few years to reach peak reliability. The 2018 facelift brought necessary interior and exterior updates, making late-generation models vastly superior to early examples.
If you prefer the older naturally aspirated V6, the Infiniti G37 serves as the direct predecessor to the Q50. For buyers wanting a coupe with identical mechanical underpinnings, the Infiniti Q60 shares the same platform and engine options.
Common Infiniti Q50 Problems
Steering System Failures
The Direct Adaptive Steering system, which uses electronic signals rather than a traditional mechanical linkage, was a major source of trouble in 2014 and 2015 models. Owners reported sudden loss of steering assist or the wheel pulling sharply to one side.
Infiniti issued several recalls to reprogram the steering control modules and replace faulty components. Later models largely resolved these issues, but early examples require strict recall verification.
Premature Brake Wear
Early model years, particularly 2014, generated numerous complaints regarding warped brake rotors and rapid pad wear. Some owners reported needing brake service much earlier than expected for a luxury vehicle.
When test driving, listen for grinding noises or feel for steering wheel vibrations under braking, which indicate warped rotors requiring replacement.
Fuel Pump Issues (2.0L Models)
Models equipped with the Mercedes-sourced 2.0L turbocharged four-cylinder engine (2016-2018) were subject to a fuel pump impeller recall. The defective impeller could cause the engine to stall unexpectedly.
Ensure the VIN confirms whether the vehicle has the 2.0L engine and verify the fuel pump replacement was completed.
Repair-Cost Overview
| Problem | Commonly Affected Years | Approximate Repair Range | Important Notes |
|---|---|---|---|
| Brake Rotor and Pad Replacement | 2014-2015 | $500 – $800 | Warped rotors require full axle replacement |
| Steering Module Software Update | 2014-2015 | Free (If under recall) | Must be done at an authorized dealer |
| Fuel Pump Replacement | 2016-2018 (2.0t) | Free (If under recall) | Affects only the 2.0L four-cylinder models |
Repair costs vary significantly by region, labor rates, and whether you use an independent specialist or a dealership. Always obtain multiple quotes for out-of-warranty work.
What to Check Before Buying a Used Infiniti Q50
- Verify the VIN for open NHTSA recalls, specifically targeting the steering system and fuel pump.
- Confirm all Direct Adaptive Steering software updates were applied by a dealer.
- Review maintenance records for regular oil changes, which are critical for the twin-turbo V6 engines.
- Test the brakes at highway speeds to check for steering wheel vibrations indicating warped rotors.
- Inspect the infotainment screens for responsiveness and dead pixels.
- Scan for diagnostic trouble codes, even if the check engine light is not currently illuminated.
- Arrange an independent pre-purchase inspection with a technician familiar with Nissan and Infiniti platforms.
