The 2004 Kia Optima LX is a relatively easy vehicle to maintain and a good choice for the average vehicle owner. Checking the transmission fluid level with reliability is no problem, as the dipstick is easily accessible in the engine bay. Not every model includes this dipstick. Changing the center brake light is easy to do, as you only have to reach through the rear of the vehicle for access. The brake fluid reservoir is easily visible in the engine bay. This will allow you to check the fluid level regularly.
Some things are problematic on the 2004 Kia Optima LX. You will have to remove the headlight housing for access to the bulb. Other models do not require the use of tools for changing this bulb.
