The 2013 Infiniti G37 X is a moderately difficult car to maintain, but shouldn’t be too hard for someone experienced in vehicle maintenance. Changing the fog light can be a problem, as you will have to crawl under the vehicle, and use a few tools, in order to reach the bulb. The tail light housing is more complicated to remove than usual, which will make it harder to complete a taillight bulb change. Removing the battery with reliability is more complicated than usual, as you will have to remove additional components using tools you may not have readily available for a repair.
Some things are easier to repair on the 2013 Infiniti G37 X. Changing both of the engine air filters is no problem. You only have to disengage a few fasteners for access to either filter, and these fasteners are no problem to disengage. The Bluetooth is easy to connect, as there are clear steps in the electronic menu for connecting your phone. Other models make this harder to complete. The components of the spare tire are easily accessible in the rear of the vehicle. This keeps the tire and jack kit ready to go in case of emergency.
