It's just a Pilot with a "bed" on it. You really won't have any issues with it, just stay up on maintenance.
Timing belt every 105k, trans D&F with DW-1 every 30k, rear diff with VTM4 every 30k, and transfer case with whatever 75w-90 is cheap at the time.
Issues are minor:
Plan on doing the P/S pressure hose. It's not a matter of if, but when. It's not fun to replace.
Wheel bearings aren't common, but aren't uncommon.
Struts seem to get eaten by Pilot's/RL's. Figure once every 80-100k
LCA's, specifically the "compliance bushings" (as Honda calls them) tend to fail around 100-150k. Replacing the entire arm is usualy the most cost-efficient.
2009 is in the year range that Honda had lots of issues with the Hands-Free modules in all their cars. They fail, stay awake after key-off, and kill the battery. Luckily, if you don't care about built-in Bluetooth technology from 10 years ago you can unplug the module in around 15 minutes and the problem is solved for the low low price of free.99
