I recently purchased a 2010 RX450H. 107k miles. So far I love the car. I am very impressed with the level of technology that was available 15 years ago. I am still exploring all that it has to offer.

I see that I am missing the under engine cover. The one that goes directly under the engine. It and any fasteners are simply not there. I am looking for advice on where to get a new cover as well as the fasteners. I see plenty of covers available from numerous sources. I assume for something as basic as this it would be ok to save some $$$ and not go the dealer route. I am having trouble figuring out what fasteners are used and where to get them.

Any and all help/advice is certainly welcomed.

 

I installed a $40 aftermarket plastic undertray on my 2013 Subaru Outback 3.6R not long after purchasing the vehicle in late 2015. Found it on autopartswarehouse.com. All the mounting holes lined up perfectly and it fit like a glove. You will find various bags of different-sized plastic fasteners on Amazon or eBay for $10 or less. They work just fine.

 

Never discard the dealer or on-line retailer option. Price them out and some items may be cheaper. [ship/wait/warranty/proper-fitment]

Aftermarket are driven by 'cost opportunity' driven and it might not be available for low demand items.

I always check salvage yards as well.

I recommend the local salvage yard a/k/a auto reccycler as there are many RXs already in retirement in such places. You probably would have to remove the cover yourself.
Bring some tools to remove it.
It has the plastic retainer pieces, which are usually removed by prying out the center first, some 10mm bolts and some larger plastic pins.
See this thread for recommended parts numbers for the retiainer pieces, which also fit several other areas on the vehicle.
