- Infiniti QX80: 73/100 (2026)
- Infiniti QX60: 77/100 (2026)
- Infiniti QX50: 78/100 (2025)

Now that we have explored Infiniti’s reliability rating by industry experts, let’s also find out what owning this vehicle would cost in the real world. Understanding these expenses can help buyers make a more informed decision.
What Are the Ownership and Maintenance Costs of an Infiniti?
The average annual repair cost for Infiniti models is $630, slightly lower than the overall industry average of $650.
Infiniti vehicles visit repair shops for unscheduled repairs about 0.7 times per year. Compared to an average of 0.4 times across all models, this reflects a somewhat higher frequency of visits.
Around 10% of Infiniti repairs are classified as major, which is lower than the industry average of 12%.
Despite some unscheduled repair costs, Infiniti vehicles bring a range of advantages to drivers.
What Are the Key Strengths of Infiniti Vehicles?
The Infiniti brand is popular for several reasons:
- Refined interiors: As a luxury division, Infiniti emphasizes interior comfort and design. Most models feature supportive seating and a refined in-cabin experience for both short commutes and longer drives.
- Advanced technology: Many Infiniti models come with systems such as:
- ProPILOT Assist (semi-autonomous driving by controlling steering, acceleration, and braking)
- Infiniti InTouch (navigation, apps, voice control, and smartphone connectivity)
- Surround View Monitor (a 360-degree camera view around the car)
NOTE: Technology features can vary by model year.
- Strong performance in everyday driving: Infiniti vehicles offer capable engines and balanced handling for a smooth, daily-driving experience.
- Enhanced safety features: Infiniti vehicles are equipped with systems such as forward collision warning, automatic emergency braking, blind-spot monitoring, and lane-departure warning. The QX60 and QX80 were also awarded the 2025 IIHS (Insurance Institute for Highway Safety) Top Safety Pick.
- Durable and reliable: While maintenance and repair frequency can vary, the likelihood of severe issues is lower than that of some competitors.
However, focusing only on the positives doesn’t tell the full story. A true understanding of vehicle dependability comes from recognizing its flaws.
6 Common Issues with Infiniti Vehicles
These luxury vehicles also come with the following disadvantages:
- Electrical problems and dashboard failures: Infiniti vehicles, especially older models, may experience malfunctioning warning lights, unresponsive touchscreens, and issues with power features.
- Transmission concerns: Some CVT transmission models, such as earlier QX60 and JX35 versions, can develop issues, including delayed shifting, slipping, or hesitation.
- Timing chain wear: Certain V6 engines may develop timing chain wear over time, often indicated by a rattling noise at startup. This reliability issue can severely impact engine performance if left unaddressed.
- Oil consumption and leaks: Infiniti vehicles may also experience higher-than-expected oil consumption or leaks, which can impact fuel economy.
- Suspension wear and ride quality issues: Over time, suspension components such as bushings and shocks can wear out, leading to a rougher ride, unusual noises, or reduced handling stability.
- Air conditioning and climate control issues: Some Infiniti owners report inconsistent cooling or heating performance.
With these common issues in mind, choosing the right model becomes even more important.
5 Most Popular Infiniti Models
These infinity models have a loyal fan base of drivers:
- Infiniti Q45: The Infiniti Q45 stood out with a powerful V8 engine, four-wheel steering, and advanced features that rivaled those of other luxury sedans of the 1990s.
- Infiniti I30: The vehicle is known as a reliable car of its time for its classy design, comfortable interiors, and a smooth driving experience.
- Infiniti Q50 Red Sport 400: This Infiniti model is known for its powerful twin-turbo V6 engine and quick acceleration, offering a more performance-oriented take on a luxury sedan.
- Infiniti G37: The Infiniti G37 reliability narrative is bolstered by its strong V6 engine, precise handling, solid build quality, and engaging driving dynamics.
- Infiniti QX55: This Infiniti SUV stands out for its coupe-style design, combining practicality with a more distinctive exterior compared to traditional crossovers.
NOTE: Availability of these models may vary depending on the car dealer and location.
Every Infiniti model, no matter how impressive, needs proper maintenance to ensure reliable performance.
How to Maintain Your Infiniti SUV or Sedan
Follow these simple practices to enhance your Infiniti vehicle’s dependability and prevent frequent visits to a repair shop:
- Change the engine oil regularly, typically every 5,000 to 7,500 miles.
- Replace the air filter every 12,000 to 15,000 miles to maintain proper airflow, combustion, and fuel efficiency.
- Monitor transmission fluid condition and replace it as recommended in the Infiniti owner’s manual to avoid premature wear or damage.
- Check brake fluid periodically. Low fluid can reduce braking performance over time.
- Maintain coolant levels and quality to prevent overheating and protect engine components from corrosion.
- Inspect brake pads regularly, as they typically wear out between 25,000 and 70,000 miles, depending on usage.
- Replace timing belts at recommended intervals to avoid any engine reliability issue.
- Change spark plugs when needed, as worn plugs can reduce engine performance and fuel economy.
NOTE: Maintenance needs can vary based on individual driving habits, climate conditions, and how frequently the vehicle is used.
A well-maintained and reliable car still isn’t immune to unexpected issues, and that’s where warranty coverage comes in.
What Warranty and Coverage Options Come with an Infiniti Vehicle?
