Odor When Outside Air Is On
I've noticed that if the fresh/recirc is set to fresh so that outside air is being drawn in, even without the fan or AC on, there's a mildew like smell in the car. I picked the car up about 10 days ago, but it's a 2013 with 13K miles. Is this a matter of cleaning or replacing the cabin air filter? DIY?

The car has definitely been sitting for a while. I'll call the dealer this morning to see if they have a cabin air filter in stock. I want to change it ASAP. Thanks for the reply. The manual tells how to change it. You just have to make sure it's in fresh or recirc first, have to check which one, as the door is locked in one of those modes.

OP, the filter is a good start. Be sure however, you've done a few searches in this forum on the subject of "mold", "smell", "odor", etc. There are many threads discussing this from different perspectives, some resolved with a new filter, others resolved in the way the owner utilizes (or not) their A/C, and some IMHO because of some very odd situations beyond what Lexus could likely prevent (like creatures getting into the ventilation system). Since your 2013 is recently new-to-you, and you likely don't have knowledge what the former owner did or didn't do, scanning those threads may help with your understanding and prevent future issues as well.
Good luck.

Instead of going to the dealer I really recommend Amazon for the filter, if you can wait. Should be much cheaper. This is the one I got for my 2015 and it works great.

EDIT: I was able to input my vehicle details and perform another search at Amazon. The filter linked to above did not fit my RX, but I found a similar one of the same brand that does. I will be ordering. The only question remaining is the direction of the arrow when installing. Any info here would be appreciated.

I didn't think it would be costly at the dealer. Thanks for the link. Now to check and see if its compatible with my 2013. There seems to be some concern as to the direction to face the arrow on this aftermarket filter when installing.

I believe they are $40 at the dealer.

Try turning on the heater
Both my Lexus and Toyota get that mildew smell once in a while from the A/C, You may have some mildew/mold in your A/C, try running your heater on high for about 10 minutes while your driving the car to dry out any moisture in the system. This always cures the odor in my situation, I also replace my cabin filters out every year, and check/clean them every 3 months.
Try this before returning to the dealer, and try to shut off your A/C a couple of minutes before shutting the car down as a normal routine to prevent the smell returning.

Picked up a quality filter at local auto supply ($16). There are some that has charcoal to reduce odors. Dealer install on other lexus (ES) has been $45. Not sure of price from parts dept. Easy to pit it in.
Does anyone know of a diagram of ventilation system... I'd really like to know how a mouse got onto the filter.

Mildew Smell
I've never had this problem being in the desert. But I've seen other posters use this type of product on their A/C system problems.
