ktderby, The only Lexus products to have the Bluetooth systems are the 2004 LS430 and the 2004 LX470. I imagine it will be in all the vehicles, trickling down as they do, eventually. Lexasm

Lexus01, First, sludge problems are completely related to the lack of oil services. If you have changed the oil/filter at reasonable intervals, I wouldn't worry about it. Second, If your car is also buring alot of fuel, you may have a faulty mass air flow sensor (air volume sensor in Lexus terms). Not all that uncommon on RX's with some miles on them. Thirdly, the transaxle is designed to not shift into overdrive until the transaxle fluid has reached 152 degrees. This is to prevent premature wear in the tranny and get the engine up to temperature faster so it meet emissions requirements faster. If this concern is particularly noticeable in colder weather, this may be the problem. Note: please make sure the fluid you used in the tranny is the Toyota T-4 fluid. According to the engineers, the wrong fluid will lead to slippage and possible failure. The only oddity is the general misfire code(p0330). This could be an entirely different problem, or ist may be related to the dumping of too much fuel into the engine. Let me know how you make out. Good Luck Lexasm

Hi, It sound like the alarm is not recognizing when the driver's door lock in the door is unlocked and doesn't deactivate the alarm. As soon as the other doors are unlocked, the alarm is recognizing them and disarms the alarm system. To check this, leave the window down, lock the car and wait for the alarm to set. Now, while looking at the alarm light, hit the button once and see if the light goes off, then hit it a second time and see if the light goes off then. Should be a pretty easy fix (cost?) if this is the problem since it's already isolated to the driver door's internal switch. lexasm Good luck!

LoyalLexus-er, The wining/whirring noise at low speed is probably coming from the right rear wheel bearing dust seal. It is not uncommon, depending on your environment, to have this sound. Please be sure thee is no danger, just let the dealer you had heard that some of these dust seals lack lubrication and are causing this noise. Good Luck, let me know how you make out. :D
