At times, the power rear door won't open by pressing the button in the dash when the engine is running (car is parked). Not sure if that's a security feature, but at times it does open... so not quite sure as to when or not ..

Does anyone notice that the wipers don't really wipe very well under the spot where the main arm connects to the wiper blades?
I had the dealer change out the wiper blades under warranty, but the same issue prevailed.

Get some rainx and treat your windshield. It will get nice and slick and help.

On the pano roof and all other glass, no prob,,, just never under the wipers in front...

I never had that issue. Might be a quirk with your vehicle/blades? Was going to apply some this weekend to my NX.

On TPMS
I read the posts concerning tire pressures and never saw the real answer, so I thought I would share what I've learned.
Tire pressures can vary considerably based on temperature, whether that is ambient temp or the heat that occurs from driving the car. If you want a graphic demonstration of this phenomena, check your tire pressures on the sunny side of the car versus the shady side on a cold day. Tire pressures can also change over time as air slowly leaks out of the tires, although a nitrogen fill can stop that.
There are optimal tire pressures for handling, tire wear, comfort, safety, and fuel economy. The tire pressure label on your car provides a good compromise pressure for all these parameters. If your driving is mostly on curvy back roads you might like your pressure a little lower to improve handling. If you drive mostly on the freeway you might choose a higher pressure for better fuel economy.
TPMS was federally mandated to warn of dangerously low tire pressures that may cause a blowout. The system is good at letting you know when a puncture is causing a pressure loss and potential for a blowout. It is also good at letting you know if you haven't checked your tire pressures lately (air does leak out over time), especially that spare tire. Unfortunately it also triggered an alarm when seasonal temperature variations caused tire pressures to fall below the TPMS set points, causing headaches for drivers and dealer service techs. The solution is to over inflate the tires so that winter low temps won't cause the TPMS to alarm unnecessarily.
According to a Technical Service Bulletin from Toyota, tire pressures should be set so that they will not go below the point where a TPMS alarm will be triggered when temps reach the lowest that can be expected in a given climate zone. The TSB provides a chart for calculating how many PSI to over inflate the tires based on current tire temp and the difference between the lowest and highest expected outdoor temps. The procedure involves setting tire pressures to the desired TPMS set point, initializing the TPMS, then inflating the tires to the correct pressure plus the indicated over inflation amount.
You can get the Toyota TSB here: http://www.toyotapart.com/TIRE_INFLA...SB-0345-08.pdf
Keep in mind that this is a Toyota TSB from 2008 and the new Lexus TPMS may not work exactly the same way, but the principles of tire inflation and temperature compensation are still valid.

thx for the reply. Got my NX end of December was told it would be about 3 months then said they would send me an email when available...

Front bumper/Wheel Well Air Vents
A nice detail discovery. I always thought this was simply a design and not functional element, but the F Sport bumper's side "vents" are actual vents that allow some air to the tires and brakes.

I think Lexus has a design flaw at least for me with the seat memory buttons location.
The buttons are located exactly at my knee height. Almost every time while I'm driving my knee will bump into the buttons and instantly my seat will start moving, sometimes to my wife's setting that cramps me up against the steering wheel. This very aggravating but i don't think there is anything I can do other than tying down my left leg.
On my last RX, the buttons were much higher on the door way out of the way of my leg. Why Lexus would put the buttons so low is beyond me.
Has anyone else had this problem? It could be considered a safety issue I think.

One more thing, its not lit up for you to choose the settings at night. I have to touch my map light to so I can see better.

The memory seats issue is interesting. On my RX, that function is locked out while driving. If you push them while underway, nothing happens. Curious as to why they didn't do that on the NX.
