Do INFINITI cars last long?

Yes—many Infiniti models can reach high mileages with proper maintenance. In recent years reliability has improved across the lineup, though some CVT-equipped models have had issues that require attentive maintenance to achieve long lifespans.


What determines how long an Infiniti will last


Several factors influence longevity. While design and engineering matter, upkeep and usage patterns are the biggest drivers of how many miles a car can reliably cover. Here are the principal considerations:



  • Consistent maintenance: adherence to the factory maintenance schedule for oil changes, fluids, filters, timing chains/belts, and brake service.

  • Transmission type and care: CVTs in some Infiniti models require special attention, regular fluid changes, and timely repairs to avoid accelerated wear; traditional automatics have their own service needs.

  • Parts quality and fluids: using OEM or high-quality replacements can improve long-term reliability.

  • Driving conditions and usage: long highway trips typically produce less stress than frequent short trips or heavy city driving with stop-and-go traffic.

  • Climate and corrosion exposure: road salt, humidity, and extreme temperatures can affect components and the underbody.

  • Recall history and timely repairs: overdue recalls or delayed repairs can impact performance and longevity.

  • Model-specific issues: some generations had reported issues (notably CVT-related in earlier years); newer designs show improvements.

  • Ownership history: prior accidents, flood damage, or neglect can shorten a car’s useful life.


Overall, careful maintenance and prudent use are the strongest predictors of when an Infiniti will need major work or reach its end of life.


Model-specific outlook: CVT-equipped vs. non-CVT Infiniti offerings


CVT-equipped family SUVs: QX50 and QX55


The QX50 and its sibling QX55 rely on a continuously variable transmission in many model years. CVTs can be durable if consistently serviced, but longevity often depends on regular CVT fluid changes and avoiding aggressive towing or heavy loads. Owners report that with maintenance these models can reach 150k–200k miles, though some early generations saw higher maintenance costs as the transmission aged.



  • QX50 (introduced 2019) and QX55 (introduced 2020 for the 2022 model year): longevity influenced by CVT health and maintenance history.

  • What helps: follow Infiniti/Nissan CVT service intervals, use the specified CVT fluid, address unusual slipping or shudder promptly.


For buyers of these models, expect potentially higher maintenance costs around the 100k–150k mile mark if CVT issues arise, but many well-maintained examples continue to run smoothly beyond that milestone.


Non-CVT Infiniti models: sedans and some crossovers


Infiniti’s traditional automatics and robust V6 engines (where equipped) have a separate prognosis for longevity. The G-series, Q50, and Q60 with reliable V6 engines and conventional automatics have demonstrated strong long-haul durability when well maintained, with owners commonly surpassing 200k miles.



  • Q50 and Q60: mixed generations; newer iterations use robust engines and 7-speed auto or 9-speed auto depending on year; with regular maintenance, long lifespans are common.

  • G37/G35 lineage and similar powertrains: historically durable with high mileage when cared for, though older models may show aging-related issues.


Overall, non-CVT Infiniti powertrains tend to show solid longevity, particularly when routine maintenance is kept up and original parts are used where possible.


What owners can do to maximize longevity


To maximize the chance that an Infiniti lasts to or beyond the 200,000-mile mark, adopt a proactive maintenance plan and stay informed about recalls and service bulletins. Here are recommended steps:



  • Follow the manufacturer’s maintenance schedule closely, with timely oil changes and fluid replacements.

  • Address any warning lights promptly and keep a thorough service record.

  • For CVT models, adhere to the recommended CVT fluid service intervals and use the fluid specified by Infiniti/Nissan.

  • Keep the cooling and climate-control systems in good shape to prevent overheating and component wear.

  • Inspect brakes, suspension, and steering regularly to catch wear before it leads to costly repairs.

  • Drive conservatively and avoid excessive towing or overloading that can stress transmissions and engines.

  • Check for recalls and service campaigns and complete them promptly.


With diligent care, Infiniti vehicles can provide many years of service across different model lines, although the cost of maintenance can rise as vehicles age, particularly for CVT-equipped models.


Bottom line


In short, Infinitis built on solid engineering with proper maintenance can last a long time, often well beyond 150,000 miles. The best outcomes come from a combination of model awareness (CVT vs non-CVT), meticulous maintenance, and attentive ownership history. Always consult current reliability reports and local dealerships for the latest guidance on a specific model year.


Summary: Infiniti’s longevity varies by model and maintenance. CVT-equipped SUVs may require more careful upkeep, but well-maintained non-CVT Infiniti sedans and coupes have a strong track record of high-mileage durability. Regular service, correct fluids, and prompt repairs are the keys to maximizing lifespan.
