The 2013 Nissan Maxima SV is a moderately difficult car to maintain. You will have to use many tools, and reach through the wheel well lining, in order to access the headlight. The lining can grow rigid and tight to the vehicle over time. To access the tail light, you will have to remove many bolts and fasteners. This will require the use of many tools you may not have readily available for a repair. The brake fluid reservoir is a problem to access in the engine bay.
Some things are easier on the 2013 Nissan Maxima SV. The engine air filter is easy to remove with reliability on this vehicle, as you only have to disengage a few fasteners for access. While it is a tough reach, the access for the cabin air filter is relatively easy, as you only have to disengage one cover for access. The engine fuse box is easily accessible in the engine bay. This allows you to troubleshoot electrical problems easily.
