Transmission fluid color and smell, and engine oil history change. Also was the timing belt changed at 90k miles....

the front transmission does have easy access to drain and fill plugs. http://us.lexusownersclub.com/forums/topic/68738-cvt-rear-differential-fluid/

No clue, Maybe a coincidence and something else is making the noise.

You are a first that I have seen...By the way did you get the thermostat with the little jiggle valve? That is pretty important when trying to get the air out of the system. You may have a clogged radiator....Also have you been using the Toyota Red or Pink coolant.....

How much did the plug change cost? I am dreading that task....I have 130k on mine....As for mileage, hey the dirty air filter couldn't help....Have you had the transmission fluid changed?

Personally I would contact the dealer, and talk to the service manager, and general manager and ask if that is the kind of customer satisfaction you can expect.

Gorgous car...enjoy and welcome aboard

How very true, We have forgotten how to pull together As Americans and solve problems logically without emotion. Our government is corrupt (both parties) and we have truly reached levels approaching 1984 book controls of citizens, and because of our apathy we are no more than pawns.

Just remember one thing, the claims of no change are strictly a sales/sell this car thing. All mechanical things are not forever....

if you have been getting it serviced there, you have good standing to get a financial co pay on the repair. Sorry, yes we on both sites do not recommend a flush because of this issue.

could be the the coolant is low in the AC unit. However maybe the heater lines also....without a picture not sure.

by the way the sensor can be had on Amazon for around $100.....

sorry to hear that the cloud of fate has hit your family so hard....Josh keep your head up, you will get past this. Your wife and you are a team and will support each other in these times of need. Nice job on the car....looks great...glad to see your posting again....thank you for your service to our country....God Bless you.

You intake manifold may be all gummed up including the butterfly valve.

here is a thread for IACV http://www.clublexus.com/forums/rx-first-generation/358579-diy-iacv-clean-picture-write-up.html

Do a search for Idle Air control valve cleaning....That is probably your problem....

first of all welcome aboard....Here is a thread that might help you...I stress buy original equipment air/fuel sensor only, many have had problems with aftermarket. Denso only..... http://www.clublexus.com/forums/rx-first-generation/340899-warning-lights.html

Mitisubishi should have brought in their diesels as in their trucks, that would have been an instant hit. As for Volvo, well the last one I like was the 122.....Maybe our government will give them a GM style bailout.

Personally I would take it to Toyota, if the cooling pump is failing you could overheat the inverter which is $7000....Not time to mess with such a system. The code on mine indicated pump failure.

My A080 code was a inverter cooling pump failure (electric pump) for the coolant. It is not an expensive part, cost around $168 new....Easy to change located on the left side of vehicle down low on the frame low and left of the radiator.....You will see two hoses going to it and it is about the size of your fist....

I don't feel doom and gloom, however everyday your rights as provided by the Constitution are being taken away. The government tells you how to manage your kids, taking away parent responsibility, the IRS takes unlawful actions to control groups, the Judicial branch monitors news groups illegally voiding the 1st amendment, our government tells employers what they will or wont do concerning healthcare, the government enacts legislation that basically prevents ownership of guns which was guaranteed by the 2nd amendment, when confronted with illegal activities by judicial branch the government fails to supply evidence (emails, etc) to Congressional oversights, when confronted with illegal voting place tactics (Black Panthers) the government looks the other way and prosecutes no one. The list goes on and on and this administration declaring transparency is so corrupt in activities that it could have been written from the rule book of Chicago Politics.....Yet people are more concerned about their latest apple iphone, you tube, or Hollywood idiot pushing their agenda. When young are asked whom is the vice president, or what the latest news event is they have no clue. We have turned into a apathetic, ignorant society, that has no clue to what is being pushed their way.

You know after looking at that pdf file, I would be tempted to reseat the rear plug on the rear motor/transmission assembly. It could very well have some corrosion. I don't know what safety procedures you would have to be aware of first, but I do know that 400 volts dc is a lot of juice. Be very careful.

I am afraid we are doomed when the young folks don't care, and the other folks on government dole don't want anything else. The poor folks in the middle working everyday and trying to support their families are targets of both sides wanting their money, in the largest redistribution of wealth that this country has ever known. I want problem solving as I have always said, but both parties are sick and more power hungry than representative.. common sense went out the door, and now we are paying and loosing our rights, our country, and any sense of good feeling.

Well this trio of fraud and deceit is amazing. The answers are I don't know, I cant remember, I don't recall, I had nothing to do with that. I plead the fifth but I am innocent. No one in this government has any morals, conscience, or honesty. And yet the average young person doesn't have a clue of whom, what, or where the government is standing. Heck most don't even know whom the vice president is. This shows the sad state of our colleges and what they teach and the lost of knowledge of our basic rights. If it isn't on you tube, they know nothing also. These are sad and very alarming details of corruption and cover up. Sadly the media is still 100% supporting this administration. So much for real reporting...and welcome the clueless.

First has the recall been performed on the inverter? It is possible you have an inverter failure and there was a recall and repair on the inverter in the Unitied States on your particular year RX. You could go to MYLEXUS.com and enter your vin # and see if possibly it comes up with that recall info. As for your other questions I dont know...Was there any other codes other than the one POA45?
