John, I do not have the ML system. I listened to one and did not think it was worth it. I am not sure if I could have ordered the option because I wanted the RES, not sure if you could have both in 06. I did not want to drill any holes. Since the install I have added a dc-dc booster. This way I can have 13.8 volts at the AMP. If you meter the +12 from the plug in the rear it can go as low as 11.5 volts. I really do not play the system up very loud, just wanted some decent lows.

i check t the voltages with a digital voltmeter today on two cars (RX400h's model 2006). charging voltage is definetly 13,8 to 13,9V. battery voltage without charging and internal lights on is between 11,4 and 12,4 volts. if i am right this would mean a nearly empty battery?! After turning the car off, the battery should be at least 12-13 Volts. 11.4 is not good, perhaps something is drawing current that should not. Any aftermarket alarms, stereo's installed. Time to have the Lexus techs check it out.

you are not the only one having this kind of problems! here in europe many RX400 users are complaining about the same "battery dead" situation. when we started to look into that we all assumed that the small 12V battery is the source of the problem. situation is that it takes only about 45 to 60 minutes with the interior light on and you can not start the car again. this happens easily also when you leave the back door open after offloading your car in the garage. after installing a scangage II (www.scangage.com) in my RX and observing the 12V voltage i found that the charging voltage is never higher than 13,9V. tho fully charge a 12V lead battery you need 14.5V. this means that my car (and so far i can only speak from my car only) is never fully loading his 12V battery. actually it is not charged for more than 50% of its full capacity. i will do the 45.000km service next week and will confront the lexus service personell with this finding. looking forward to see what they will tell me. i am very interested to see if only my car is loading with only 13,9V. have anyone measured his 12V power when the car is in "Ready" state? regards williz I just looked at the scangage web page. That device uses the OBII socket. It is possible the battery voltage AT THE BATTERY may be higher than the connector shows, depends on what the current load is at the OBII side. If you have a digital voltmeter please veriify by taking an actual reading from the battery. 13.8 is a float voltage used on many standby batteries. Since the main battery does not start the car, could be one reason they run it lower. My battery is usually 13.8 to 13.9 volts.

I asked the dealer to look into this at my last service. They claim it is not a known problem. It is annoying. what are we are breathing in. Any lab people out there? CSI where are you!!! Hi, Did you ever find the source of this? I noticed it in my vehicle last night. White particles over the dash/console etc... The windows are always up at this point given the weather in New England is still cold. So I don't think it came from an external source. Jim

I would really appreciate help. My phone is Verizon RAZR. thx Why not just post it. I am sure others would would find this useful. I used a siemens s56 and put my 10 most used number in that phone, then transfered those 10 to the RX400. This gave me the names to go with the numbers. I am using a V815 Verizon phone.

Take a photo, time date the imprint with your favorite photo program. A little safer to store the photo than a used filter. Save receipt as well.

I don't think we will ever know, or it really did work at all. Once in a while a new member will drop a post just to see what discussion it starts.

This is interesting ,my 06 400 has the res. I cannot play an mp3 dvd inserted in the rear player. What format is on the dvd to play mp3's? I burned mine as an iso dvd. It's not a ML system, but I don't think that is the problem.

What year is your RX400?

I was under the impression the RX400 uses the rear electric motors for reverse? The trasmission (CVT) does not have reverse. You may think the motor does this but I have been in reverse with only the electric motor.

Yes Lexus did move it. I have never had the car near water. I scraped the rusty paint off today and sprayed 4 coats of high temp engine paint on the brackets. Both sides were about the same.

No tissues in my car since I ran out weeks ago. Twice in 4 days wiped the dash clean, then saw the dust again.

I was at the dealer today. Showed them the context here and my white particles. They said they did not know where it was coming from. Then said perhaps if there is a TSB they will be able to fix the problem. Very dissapointed. What shall we do next?

Here is the picture. The dealer claims they can't help me with this.

I just noticed today the white dust on the dash. Car was washed 4 days ago and the dash was clean then. Windows have been closed. My garage is a two car garage behind my house, no white dust there.
