The 2004 Buick LeSabre Custom is a relatively simple car to maintain. The brake fluid reservoir is easy to find and has simple-to-read level markers. The transmission fluid dipstick is no problem to remove with a reservoir opening that makes refilling it easy. The spare tire and jack kit are conveniently packaged together, which allows for reliable access in the event of a flat.
However, the 2004 Buick LeSabre Custom does have its share of lengthy procedures. The tail lights are spread across two large bulb housings that are bulky and cumbersome to remove. The center brake light is not an LED bulb, which means it will require more maintenance over time than other models. The battery and interior fuse box are located underneath the rear seat, which is an awkward and unintuitive location.
