Is the 2006 Infiniti G35 reliable?

Overall reliability is solid for a performance luxury car of its era, especially with consistent oil changes and timely repairs, but you should plan for age-related sensor, suspension, and minor electrical issues.

What are the most common 2006 Infiniti G35 problems?

Commonly reported issues include oil consumption or valve cover gasket leaks, crank/cam position sensor failures causing stalling or no-starts, front suspension bushing wear, and window regulator/door lock actuator failures.

Are maintenance costs high on a 2006 G35?

Costs are typically moderate for a luxury performance vehicle—higher than an economy sedan, but often less than comparable German models. Tires, brakes, and suspension wear can be the biggest recurring expenses if driven aggressively.

What are the best years to buy for an Infiniti G35?

Many shoppers prefer later-year examples within each generation due to incremental fixes and updated features; condition and service history matter more than the exact year, so prioritize a well-maintained car with records.

What should I check before buying a used 2006 Infiniti G35?

Check for oil leaks/low oil level, scan for engine codes (especially related to crank/cam sensors), inspect front suspension for clunks and uneven tire wear, test all windows/locks, and confirm transmission behavior (smooth shifts on automatic; no grinding or clutch slip on manual).
