My GarageAre Used Infinitis Reliable?
Short answer: Infiniti is Nissan luxury — which means the VQ35 and VQ37 V6s are excellent and the platforms are largely durable. Unlike Nissan's mainstream lineup, most Infinitis use conventional automatic transmissions rather than the CVT, which is a major reliability advantage.
Choose the naturally aspirated V6 models when possible. The newer 3.0T twin-turbo V6 is potent but less battle-tested. Ownership costs are close to Lexus and well below German competitors.

Models to Research Carefully
Not deal-breakers — but they reward a careful buyer.
Same Jatco CVT concerns as the Pathfinder. Fluid service every 30k is critical — verify history.
Rare hybrid; battery service and dealer familiarity vary by region.
Newer twin-turbo V6 — much less long-term data than VQ37. Direct injection carbon buildup is a future consideration.
Best Infiniti Engines
Powertrains that have earned a bulletproof reputation.
M35, QX60, older G35. One of Nissan's best.
G37, Q50, Q60, QX70. Refined evolution — timing chain guides deserve inspection past 150k.
QX80. Truck V8 with a strong record.
Engines to Research Carefully
Not deal-breakers — but they reward a careful buyer.
Powerful and refined but newer. Direct injection means carbon buildup is a long-term consideration.
Common Problems
Bring this list to your pre-purchase inspection.
- ✓Timing chain guides on VQ37 at high mileage
- ✓CVT longevity on QX60 without fluid service
- ✓Trunk hinge rust on older G37
- ✓Steering rack seals on early Direct Adaptive Steering
- ✓Fuel level sender inaccuracy on some Q50s
Maintenance Costs
Infiniti service costs sit between Nissan and Lexus. Independent Nissan-familiar shops handle most Infiniti work identically.
The VQ V6s use conventional service intervals and standard fluids. The only exception is the CVT-equipped QX60, where 30k CVT fluid service is essential.

A used Infiniti is a strong value if you pick the powertrain carefully. The important buying factors are:
- • Powertrain — VQ V6 models are the safest bet
