The INFINITI G37 features a timing chain, rather than a timing belt, which is beneficial as chains are typically expected to last the lifetime of the vehicle. It is commonly covered by warranty for around 10 years or 100,000 miles. If your vehicle's timing chain encounters problems, you may observe engine misfiring, decreased motor performance, metallic shavings in the oil, engine starting issues, dashboard warning lights, or shaking and rattling while idling.
Common issues with the timing chain in INFINITI G37s typically stem from issues with the timing chain guides.
