It can be a reliable used luxury sport sedan when maintained well, but it’s not “set-and-forget.” Staying on top of oil level, sensors, and suspension wear is key to long-term dependability.

What are the most common 2005 Infiniti G35 problems?

Frequent issues include oil consumption or valve cover leaks, cam/crank position sensor failures causing stalling or no-starts, front suspension clunks from worn bushings/links, and occasional window regulator or door lock actuator problems.

Costs are typically moderate for a luxury-branded car. Routine items are reasonable, but repairs like suspension refreshes, sensor replacements, and fixing oil leaks can add up, especially if you’re paying labor at a shop.

What are the best years of the Infiniti G35 to buy?

Many shoppers prefer later first-generation years and well-maintained examples with service records. Condition and documented maintenance often matter more than the model year alone.

What should I check before buying a 2005 Infiniti G35?

Check for oil leaks and low oil level, scan for stored engine codes (especially sensor-related), test for smooth starting and idling, listen for front suspension clunks, verify transmission shifting, and review service records for fluid changes and prior repairs.
