I wanted to mention that the dealer set us up with a 2011 RX350 as a loaner for a couple of days and my wife and I both agreed that we liked her RX400h better, even with 81K miles on it. The 350 with 12K miles on it had a little better stereo and much better navi, but other than that we wouldn't trade ours for the 350. When my wife picked up her RX, they had sent it through their detail area and her's was looking all clean and shiny at the front of the lot. She was happy to get hers back.

Well I have an update on my wife's 06. Dropped it off at the dealer last Thursday and had a couple of recalls done along with some analysis in the whinning noise that was haunting us. They ended up replacing the driver's side wheel bearing along with the transaxle fluid, which they said was adding to the noise. We also had them chnage the oil, program a key we bought a while back off ebay, do a four wheel alignment, and escaped for right at $900.00. Here's a breakdown of the charges: Wheel bearing $377.00 Alignment $159.00 Transaxle Fluid Change $161.00 Oil Change $61.00 Key Programming $63.50 It seems to have fixed the problem. The RX is running like a champ again. Now we will have to deal with the Power Invertor Recall when the parts become available. Just received the notice on that recall in the last week or so. Plan on doing the ISC Reset to see if I can get some better mileage out of the vehicle, but so far it has been great.

At this point, although I think I could do the wheel bearing myself, other than pressing out the old bearing and pressing in the new one, I may just drop it off at the Lexus Dealer and have them diagnose the issue. I don't have a local dealer, but have used Plaza in St Louis and plan on being down there tomorrow. I hate to pay a dealer to do work I can do myself, but not knowing for sure what may be causing the problem, I don't want to just throw money at it. I also have the rocking motion issue at 70 mph, so I will have Lexus perform that TSB when I have it in the shop. I will let you now what I find out. Thanks for your feedback.

I don't think the tires are the culprit in this case. It sounds like the noise is coming from the driver's side front wheel. The tires have only been through one rotation and I dropped some good coin on the Parada Spec X's, which drive and handle very well. My son had a wheel bearing go out on his 99 Accord and we replaced the entire hub for about $50.00. He was having the same type of noise from the rear wheel on his car and the noise seemed to build over time and became more noticeable at lower speeds. All very similiar to what we are experiencing. I haven't seen any information on wheel bearing problems with the Lexus 400h, but I may just be one of the first.

Well my wife's 2006 Rx is getting up in the mileage at over 80K, and we are noticing a whining sound as you start to build up speed. It starts at about 40 mile per hur and gradually builds as you continue to move up the speedometer. I am wondering if a wheel bearing mightr be going bad. I am going to pull the rear wheels and look at the brakes, but I would be surprised if it was the brakes. Has anybody else experienced this problem? Any suggestions?

I recently put new tires on my wife's 400h and we absolutely love the Yokohama Parada Spec-X we put on the vehicle. They handle great in all weather conditions and road noise is non-existent. We have only had them on the vehicle through one tire rotation and they are wearing evenly. Only time will tell on how they wear long term, but I do believe the Parada Spec-X is a softer compound than some of the other tires available. My number one concern is safety with quiet/comfort coming in second. The mileage I get out of a set of tires doesn't really concern me unless they only last 30K.

I purchased a preowned 2006 Rx400h with about 40k on the odometer and did a bunch of research on the batteries before I made the move to purchasing the vehicle. Basically I found out that Lexus warranties the drive batteries for 100K miles but even then, unless something radical happens you can replace the individual cells without having to replace the entire battery bank. If I remember correctly the vehicle has 25 or 28 Lithium Ion cells that make up the battery bank, and they can be replaced individually if needed. From all my information gathering I think it is very rare to have to replace the entire battery bank and like many poeple on the forum have relayed there are vehicles with 200K+ that have never had an issue with batteries.
