There isn’t a single “bad year” for the Infiniti QX50. Reliability varies by generation and model year, with the earliest QX50s (born from the EX) more prone to transmission-related complaints, while the newer VC-Turbo-powered versions have generally improved reliability but can still present teething issues for early adopters. The best approach is to consider the generation you’re buying and check vehicle history and recall status.
Generation overview and what it means for reliability
The Infiniti QX50 has evolved in two main generations. The first-generation model, introduced as the QX50 in the mid-2010s, used a conventional powertrain and CVT in many configurations. The second generation, starting in 2019, adopted Infiniti’s VC-Turbo engine paired with a modern automatic transmission and a refreshed chassis. Each generation has its own set of typical issues, and “bad year” can depend on which version you’re evaluating.
First generation QX50 (2013–2017)
Owners and observers have most consistently flagged issues in this early period, where the vehicle lineage traces back to the EX. Below is a summary of the commonly reported concerns for this generation.
- CVT reliability concerns: several owners reported transmission shudder, hesitation, or the need for transmission work or replacement.
- Oil consumption and related engine wear: some models showed elevated oil usage, leading to more frequent monitoring or servicing.
- Electrical and infotainment glitches: intermittent screen freezes, navigation issues, and other software-related faults.
- Steering and suspension quirks: occasional reports of unusual steering feel or rattle complaints, sometimes tied to aging components.
When evaluating a first-generation QX50, buyers should pay particular attention to the vehicle’s transmission history, verify that the CVT has been properly maintained, and review service records for any oil-related concerns.
Second generation QX50 (2019–present)
The 2019 refresh introduced Infiniti’s VC-Turbo engine and updated drive dynamics. While reliability generally improved with the new platform, there are still notes to consider in this generation, especially for early adopters and certain markets.
- VC-Turbo engine teething issues: some early models reported software updates and occasional performance quirks as the engine calibration matured.
- Oil consumption and cooling considerations: a minority of owners reported higher than expected oil use or cooling system quirks in the first year of production.
- Infotainment and connectivity glitches: occasional software updates were needed to address freezes or lag.
- Recall and service campaigns: like many modern cars, this generation has been subject to recalls and safety campaigns; VIN-specific checks are essential.
Overall, second-generation QX50 models have benefited from newer hardware and improved reliability, but potential buyers should still review recall history and ensure the VC-Turbo engine has been properly serviced and monitored.
What to consider if you’re buying a used QX50
Before you buy, use this guidance to vet a QX50’s condition and history. The list below helps you focus on the most consequential checks for reliability and ownership costs.
- Check for CVT service history on first-generation models: confirm there are no persistent shuddering incidents and that the transmission has been serviced according to Infiniti’s guidelines.
- Review engine oil consumption records: look for consistent oil level checks and any corrective maintenance noted by the dealer.
- Inspect electrical systems and infotainment: ensure navigation, Bluetooth, and screen functions operate smoothly without repeated resets.
- Verify recall repairs and service campaigns: obtain a VIN-based recall report to confirm completed corrective actions.
- Inspect the VC-Turbo (2019+): listen for any abnormal engine noise, check for smooth acceleration, and review maintenance records for cooling and oil management.
- Get a thorough pre-purchase inspection: a qualified mechanic can assess transmission behavior, engine health, and overall drivability across both generations.
Consult multiple sources when assessing a specific year, including consumer reliability reports, owner forums, and VIN-specific recall data to form a balanced view of risk for the exact car you’re considering.
Summary
The Infiniti QX50 does not have a single universally “bad” year. Early first-generation models (roughly 2013–2017) carry more frequent reports of CVT and related drivetrain concerns, while the 2019 and newer second generation generally benefits from newer engineering but can still present early-adopter issues and recall campaigns. For a reliable purchase, identify the generation, check service and recall history tied to the VIN, and obtain a professional pre-purchase inspection.
