Your FX45 doesn't have an expiration date, but its battery does. Generally, car batteries last from three to five years. Check your battery regularly and replace it as needed so it doesn’t leave you and your Infiniti FX45 stranded. Watch for signs that your current battery is getting too old or too weak. A sluggish engine start, an illuminated check engine light or battery signal, bloated battery case, corroded battery terminals, or faded headlights can all signal that your battery is waving goodbye.
