Is the 2007 Infiniti G35 reliable?

It’s generally considered reasonably reliable for a performance luxury sedan, especially when maintained well. The engine and chassis are strong, but age-related oil leaks, electronics, and transmission wear can affect higher-mileage cars.

Common issues include oil consumption, valve cover/timing cover oil leaks, occasional automatic transmission shift concerns, and failures of items like window regulators or door lock actuators.

Are maintenance costs high for a 2007 Infiniti G35?

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

Many shoppers prefer later models within each generation due to minor refinements, but condition and service history matter more than the badge year. For the second-generation sedan, well-maintained examples from the 2007–2008 range are commonly sought.

What should I check before buying a used 2007 Infiniti G35?

Check for oil leaks and low oil level, review maintenance records, test for smooth transmission shifts, inspect suspension/tires for uneven wear, and verify all electronics (windows, locks, infotainment, A/C) work properly.
