Hi Denny No I don't have a thermal sensor gun. I am indeed figuring out a way to measure the temp at cover level. I will keep you posted. Thanks for the support! Regards Paul.

Ok. I am a simple mechanical engineer: I don't trust things becoming warmer than common sense explains.

Hi I have noticed that the central radio / climate control unit is rather warm on the outside. Even if the radio is off. Any ideas if this is normal? Regards Paul.

Dear all, I have an intermittent sqeaking sound when the steering wheel is shifted towards me. Specifically when the car is parked for a longer period in the sun, the chances of hearing this sound are bigger. But not always though ..... I got a video clip of the noise; see attached. I brought the car to the dealer for maintenance (timing belt replacement) and asked them to check for this issue. As always: the steering wheel worked fine .... :-( Is it do-able to check this motor/gear myself? The squeaking sounds like it needs some lubrication. From an earlier post (Jan-2013) I got feedback that I need to remove the knee airbag. This did not sound like an easy job. Regards, Paul. Steering_Wheel.wmv

Hi Mason, Thanks for the reply. I will check the energy screen next time; it's a good tip. The reason I expect the ice stop running, is that you can feel the car holding back a little. Similar like lifting your right foot of the gas. Regards, Paul.

Hi, I have a strange issue with the combustion engine on my RX400H. At approx 50mph (80km/hr) the combustion engine suddenly stops running for 1 second and then fires up immediately. If I check the power gauge I see the needle drop and then immediately jumps back to 'normal'. If I lower or raise the throttle (so away from the 50mph) the issue disappears. Any ideas? Regards, Paul.

Hi Thomas, Probably a digit-typo: see screenshot .... For those RX models not already equipped with the factory Roof rails (the rails parallel with the vehicle - perpendicular to the cross bars) is the RX Roof Rail Kit. Includes both left and right rails as well as each rail cap and hardware. Note: Cross bars not included Availability: Ships within 24-48 hours Options: Roof Rack Kit Also Fits: RX330: 2004 - 2006 RX350: 2007 - 2009 RX400h: 2006 - 2008 In Store: $2026.20 Online: $1685.19

Hi James, Yes, this issue is related to the telescopic function. Looking at your comment ("requires removal of the knee airbag ...") I better have this fixed at the dealer .... ;-) THANKS!

Hi, My RX400 is making a squeaking sound when the steering wheel shifts towards the driver (at start up). Any idea's? As with most of these sounds: this is also intermittent. If it occurs more frequently, I will make of video of it. Thanks, regards, Paul.

Hi Dr. RX400h, If you follow Maseace's link and then click on "View Part Diagram" also the other rails are shown (and can be purchased). I've been looking for the same (used) roof rails half year ago without any luck. I did see a few offers on e-Bay but having the stuff from the US to the Netherlands was a bit too "difficult" (and costly). According to this link, the Avensis roof rails should also fit: http://www.lexusownersclub.co.uk/forum/index.php?showtopic=70124 Good luck hunting! Regards, Paul.

Hi, Today I heard the rear door motor (Lexus RX400h) making a squeeking kind of sound. Like it needed lubricating. Does somebody know how to reach this motor? Regards, Paul. PS: I've checked this Hybrid forum on key words like "rear door" and "rear door motor". Haven't found anything though .....

I have an appointment with the dealer tomorrow (to repair something else in the car). I will print the ISC reset procedure. By the way: fact is that I drained the battery (not the main "hybrid" one) because I kept the doors open too long (leaving the interior lights on). So the ISC reset might be a smart to do anyway. But also: this "draining" took place after our holiday to France. So this is not the cause of the first "rattle" I heard ...... I'll keep you posted. UPDATE 29-Aug: No news yet. The car is in the garage to fix the above mentioned "something else" (a squeek in the body work). This is not finished yet; they need to remove interiorparts/lining to check one of the beams on the left side of the car. UPDATE 1-Sept: In the garage (a non-Lexus dealer) works one guy with (apparantly) 7 years experience in a "true" Lexus-garage. He was familiar with ISC-learning (he read the hardcopies I gave). He contacted (a couple of years ago) Lexus about this way-of-working and their comment was "the learning procedure for US differs from European Lexus's". He explained that in the US the ISC learning procedure sort of "stores" the settings and European cars don't. In European cars the "learning" is triggered every so many times and executes the learning-cycle automatically. He claims that by reading the car's memory/loggings, you can trace back the learning cycle and that the results are OK. So they repeated their statement: "All Lexus RX's have this issue more or less". So, my conclusion: I leave it at this for now. My main concern was that (since it is a used car) I get unexpected failures-costs lateron. Appart from this being a strange `noise` my objective was the garage to have focus on this issue, so that in the future (after warranty expires) I can remember them on their statement. Thanks again for all comments/tips. Regards, Paul

Hi, an update and some answers. The worst "rattling" we've heard after our holiday to France, has not happened anymore. In itself is that OK ..... But with an "engineering background" I don't believe in indicents and I keep worrying until I understand the root cause ... @Katzjamr: Your description fits my situation. Always from parked position, and not always present. @Lemon: Does the ISC reset also apply for European 2005 model? I will check this with the dealer anyway. Thanks, regards, Paul.

Hi Dave, Thanks for the quick reply. Yes, there is another dealership in my area. It is a good idea to get a 2nd opinion. Thanks, Paul. PS: I tried a few times to reproduce the "error" and make a video of it. No "luck" so far .....

Dear all, Two months ago I purchased a 2nd hand RX400h (year 2005, 132.000km). The car makes a strange rattling sound when the combustion engine starts. I've checked a German Lexus forum (see: http://euro.lexusown...showtopic=32401) and have the car also checked by the garage/workshop. The workshop's mechanic's statement is: "All RX's show the same behavior, more or less". This mechanic claims he has 7 years of Lexus experience. Now some background information. I live in the Netherlands and we've had our summer holiday in France. Which is 2.400km back and forth (approx 1.500 miles) without any issues . But the next day after returning home, the car starts with a rather loud "rattling" noise. After opening the hood, I thought the combustion engine was running on 5 out of 6 cilinders: you could see the engine shaking. Current status is that this sound is not always present. Guess is once out of three starts I hear the same sound. Funny is that, if the car has moved a few feet, the sound is gone. Explanation of the garage is (sorry, my technical english is not that good): - The car has no "real" starting motor. So when the combustion engine needs to be started, it uses the electro motor in the gear box to fire it up. - And (according the mechanic) there is some physical play (mm's) between electro motor, gear box and V6. It is this play that is causing this "rattling". - And also: it is also depending on the exact position (rotation-wise) of the electro motor. If the electro motor is in a "unlucky" position, it might take some time to start the V6. - Final statement is that also the new 450 has this issue. It has been improved, but it is still present. According the mechanic. From both this forum and the German forum I came to the conclusion, that apparantly I am the only one having and RX with this issue ..... Which is obviously not in sync with the garage's statement "all RX's have this issue". I am planning for making an audio file and upload it here. But still I am curious about your experience!! Warranty will expire in 3 months from now ...... Regards, Paul. PS: the feedback I got from the German forum about this issue was not conclusive. I got tips like: - check the condition of the spark pugs - check the condition of the oil; it might influence the hydraulic dampers between camshaft and valves
