#3235 of 9498 A little lesson
Oct 01, 2001 (11:30 am)
There are two types of people in the world, those who like to help, and those that just like to show how smart they are and hear themselves talk. Continually.
I took the findings alledged here about how the RX300 4WD is not permanent and emailed them directly to Lexus Corporate yesterday. Here is their response unedited (except for my bolding):
Thank you for contacting the Lexus Customer Satisfaction Department. I apologize for your concerns with the information you have received regarding the 4WD RX 300. The following is the information we have on the 4WD RX 300.
Automobile manufacturers continually try to make their four-wheel-drive systems simple to use. Lexus has accomplished simplicity by providing the four-wheel-drive feature on a continual basis, so that it occurs automatically without driver input. The system provides the proper power transmission ratio between front and rear axles, based on surface conditions. Because the connection is through a viscous coupling with disc plates, power transmission is smooth and seamless -- barely noticeable even when power is nearly evenly split between the front and rear axles. Common customer concerns like axle windup, wheel hop, and other conditions related to four-wheel-drive are virtually eliminated with the viscous coupling.
The viscous coupling is two sets of disc plates mounted closely together in a fluid. When the front and rear axles turn at different speeds, these plates resist moving relative to each other. When driven on low-traction surfaces, such as snow or gravel, this resistance in the viscous coupling will help direct power to the axle that has the most traction. When driven on a normal, high-traction surface, the four-wheel-drive RX300 viscous coupling distributes power approximately equally to each axle.
Regarding the 2001 4WD RX 300 with Traction Control (TRAC) and Vehicle Skid Control (VSC) - In addition to the benefits of 4WD on limited traction driving surfaces, if a drive wheel or wheels loses traction, TRAC will direct power to the wheels that still have traction and brake the spinning wheel(s). Additionally, VSC will help the driver manintain control when cornering on limited traction surfaces.
Predictably, there will of course be a response to this from someone who just likes the sound of their own voice.

Holy cow, Lexus corporate has an e-mail address now? One year ago, I had to use the phone to even get in touch with them, talk about technological advancement...
Hi, how are you Tarik

They've had it to my knowledge since the beginning of the year. Do you have an "owners log-in" at Lexus.com? You give them your VIN# and a password, and they bring up your car details. It's great, it even keeps a log of any emails you send them in your personal FAQ section. Responses are always within 24 hours. Try it.
#3238 of 9498 15000 mile check up costs how much?
Oct 01, 2001 (1:15 pm)
Hi, apologies if I am in the wrong group (correct me and I will post there) but would appreciate feedback on maintenance service for Lexus rx300 for 15000 miles. Called the dealer and was quoted at $450. Personally that is ridiculous for the cost of what is listed in the manual for the work done. Can only imagine the cost for the next service check after that. My question is where do fellow RX300 owners go for service? Toyota? Any problems using them? Yes I can hear some say if you can afford a Lexus you can pay that price for service but if one does not.
Any feedback appreciated.

I've been taking my GS 300 to the Toyota dealer for 5 years and have had great service including timing belt and water pump change (preventative). Will be doing the same with my RX 300 for oil changes and anyting it needs after warranty expires (if I keep it that long). I have no qualms about using Toyota dealership. Your experience could vary of course but I've been most satisfied.
#3240 of 9498 Lexus keys
Oct 01, 2001 (1:37 pm)
I know I've seen a post regarding remote keys but it was long ago and would take forever to find it so I'll ask for the info without a lengthy search. I've lost one of my two remote keys for my GS 300. Any ideas on a reasonable place to get replacements. Obviously I could use the dealer but I avoid that rip off whenever I can. Any help on this would be appreciated. Thanks.

The only thing I would add to this discussion is that service prices can vary from dealer to dealer. I recently called around for 30K service on one of my other vehicles, the prices were all over the map for the same 30k service!
If you want Lexus to do the service (the Toyota idea is good also), then get a price quote from all the dealers in your area. Take the low price and call back that dealer and make them list what you are getting for that price. All you need at a minimum is what's listed in your owner's manual for 15K miles. If they do everything that's in the manual and the price is the lowest (and reasonable), then you have your answer.
Hopefully you have more than one Lexus or Toyota dealer in your area. Let us know how it goes.
P.S. Always save your service/repair bills and receipts!

Took me awhile to figure out what you meant, sorry about the mis-spelling, it wasn't intentional. I tend to only use the spell checker if I know I have stumbled over a word, missed that one. Most of my reverse letter typos get by for the same reason, over-confidence.

I get the definite impression from you that it would be okay to be a "know it all" providing everything one knew/learned was PRO Lexus.
That will never happen, not just me, you're simply living in the wrong world.
Did you go back and read the fog light link more carefully? Do you own me and others on this board an apology for your attempts to mislead?
I'm glad you got a better resonse than I did from Lexus regarding this matter, all I got was a referral to the dictionary meaning of viscous.
Now, go read the information that you got from Lexus again, where do you see that it says I'm wrong?
The strongest statement I see is the one that you high-lighted. If all four wheels have traction who cares what the torque distribution is, what does it matter?
The important thing to note is: How would you go about proving this statement wrong, even if it is absolutely incorrect?
Oct 01, 2001 (2:30 pm)
Go draw yourself the simplest sketch you can imagine of the viscous clutch as described by Lexus themselves. Two clutch sets of clutch et immersed in a viscous fluid connecting the front and the rear axles.
Now ask yourself: "Where is the power input?"
The answer is from the front axle, THROUGH the viscous clutch, to the rear axle. Even there statement, while technically correct, is totally misleading.
If the RX is rolling along with all four wheels having traction with the roadbed how do you determine whether of not all four wheels are being driven with equal torque? And furthermore why does it matter?
