Bob, did have this streaking (between laminates) L430. I did not know the reason why, but perhapes the ammonia was the reason. Had to have glass replaced.

Streaking between laminate by bobloveslexus
Sep 07, 2006 (8:02 pm)
That's the same problem I had with the Hatteras. We replaced thirteen old windows. Inside of 60 days three had the separation between the laminate. The glass company replaced three windows; on the fourth "claim" by me, they asked about ammonia. Problem solved! We don't use ammonia-based glass cleaner at home or on the car.
 
Best regards,
Bob

I noticed that the Owner's Manual for the 2006 LS430 indicated that the windshield and driver/passenger windows were coated with a rain repellant substance. Their recommendation was to clean those surfaces with a clean cloth and water (if I recall correctly), no prepared glass cleaners should be used. I acknowledge this has nothing to do with laminates but does apply to glass cleaning.

Wow, I never knew that about the ammonia. I haven't cleaned these windows too often but I know that's not the problem right now, and will stop using the windex. It sort of makes one worry about the products a "detail shop" or car wash would use on them.
 
Perhaps a weak vinegar & water solution would work. Beats me why all the accumulated film goes streaky. The windows on our '05 LS do seem to have a 'finish' on them, inside and out, almost like Rain-X was put on at the factory. I'll dig out the owner's manual.
 
Thank you again, everyone, for your input.

The detail shops (around here anyway) seem to be in the know on this. I've not seen them use ammonia anyway.

I believe they do that for safety reasons. I have an '06 LS430 and my problem is with the voice activation. It responds to only a few commands. Do you have any better results?

Mine responds to all kinds of commands....some of them even correctly.
 
I believe there is a mode to condition your tonal inflections into the system, it has you say certain words, and that conditions the responses better.

99 LS400 - My Experiences by mikeyinmo
Sep 16, 2006 (8:20 am)
Hello to you all from SE Missouri.
 
I have read all the postings over the last few days and have learned a lot. Thank you.
 
I would like to add my personal experiences to this growing data base.
 
My first LS was a 3-year-old '94 CPO with about 35K on it. No remarkable problems and I traded it in at 85K to acquire my present Lexus.
 
I purchased my '99 LS in April '02 as a CPO with 25K miles from Superior Lexus in Kansas City. It currently has 80K on it.
 
At the 60K dealer service, they replaced the PS pump and idle-up valve under warranty ("leaking"). Obviously, Lexus still has not corrected the flaws in this unit. However, I intend to take the Forum's advice and have the fluid changed and screens cleaned at the big 90K tear-down.
 
At 60K, they also replaced the starter with a re-man unit after I told them it had failed just once to turn over in my garage (apparently an issue with a dead spot).
 
And they also replaced front strut rods ("torn")at 60K. All told, this warranty work was worth $1600 and I paid zero.
 
Other minor things replaced under warranty was the driver's door stop (made creaking noise when fully opening door; unbefitting this machine), new fog lamp switch (fogs kept blinking off and on), new TPS (limped two miles home in first gear with no throttle response; but it reset itself after setting for half hour in my garage, allowing me to get up to KC for repair) and new steering wheel tilt motor (just failed one day).
 
All in all, Superior Lexus treated me great during the CPO period, which, alas, has now expired.
 
My local Firestone handles all my 5K and 15K services (they use a flushing machine on the tranny) and I let Superior Lexus handle the 30K, 60K and soon to be 90K services.
 
Knock on wood, I have not had any of the electrical glitches and horror stories I have read on the Forum (other than the TPS, which was really spooky, and NOT covered under the Owner's Manual. When I called the dealer and described what happened, he knew exactly what was wrong.
 
Anyway, sorry for the length of this posting - I just wanted to add my two cents to the database.
 
I have a tire question which I will ask in a separate posting (but I think I already know the answer).
 
Happy motoring!
 
Mike

99 LS400 - Tire Noise by mikeyinmo
Sep 16, 2006 (8:49 am)
I bought my LS as a CPO with 25K on it. The car came with brand new Dunlop SP Sport 4000, P225/60R16 97V M&S tires, rated 240 treadwear, Traction A & Temperature A.
 
I kept them aired, balanced and rotated and managed to get 46K out of them. They were grippy and quiet.
 
At replacement, Firestone quoted me $780 for identical new Dunlops and, as an alternate, $500 for Bridgestone Fuzion ZRi, P225/60R16 98W tires with 320 treadwear and A's on traction and temperature.
 
Both prices included mounting, balancing and 4-wheel alignment. Looks like a no-brainer, right? WRONG!
 
First of all, there is no M&S rating - none whatsoever. I discovered this after a two-inch snowfall where the car fishtailed and the ABS, TRAC and VSC lit up the dashboard.
 
Well, I guess I can live with that - it doesn't snow much anymore around SE Missouri and being retired, there is no place I absolutely have to be.
 
A larger problem in the road noise. After 6K, I had Firestone rotate them (uni-directional) and over the ensuing 4K miles, the road noise just keeps getting louder and louder. It starts building at 5mph and really starts to sing at 25-45mph. Sounds like I have aggressive snow tires on all 4 corners. And the smoother the black-top, the more pronounced is the hummmmm, or whirrrr.
 
It got so bad that I had Superior Lexus do a thorough inspection of brakes, bearings, bushings; the entire underside, just to be sure it wasn't something mechanical.
 
They said everything underneath was to spec and it was just the aggressive tread. And they didn't charge me a dime for the underside inspection.
 
This will be an issue between me and the local Firestone. Apparently they had an incentive to push this product and totally missed the tread noise and lack of M&S rating.
 
From studying the Fuzion ZRi website (after the fact), I learned that this tire is aimed at the tuner market and in fact, the 225/60-16 is the highest profile tire they make - most of the line is wider, lower profile and probably noiser tires.
 
I think I know the answer; Michelin MXV4+. But meanwhile, the 320 tread Fuzions are going to take FOREVER to wear out.
 
Oh, well; live and learn. Thanks for listening.
 
Mike
