The 2009 Hyundai Genesis 4.6 is a moderately difficult vehicle to maintain, but shouldn’t be too hard for those experienced in vehicle maintenance. Changing the headlight with reliability is no problem, as you will have to use many tools to complete many steps for access. Other models make this easier. You will have to lower the glove box for access to the cabin air filter. This would have been easier if there were access panels in the rear of the glove box instead. Changing the reverse light can be difficult, as you will need to remove many fasteners, and peel down a lining, for access to the bulb.
Some things are easier on the 2009 Hyundai Genesis 4.6. Changing the engine air filter is no problem, as you only have to disengage a few fasteners for access to the filter.
