#1620 of 2081 568 thousand miles on a 90 lexus
Jul 17, 2005 (7:32 am)
FYI 568 thousand miles was accomplished by a 1990 lexus LS 400 when traded in after 15 years on the road, the engine and transmission were original. The only failures were the
air conditioner compressor and 2 power steering pumps. The car is from Southern California
and had good maintenance, several dealers have said that if you take care of your lexus it's not a big deal to go 300,000 to 400,000 miles. According to JD powers the 2005 lexus is the first car to be under 100 for consumer complaints ever recorded shows again just how superior they build them year after year.

I've heard that about the 1st generation LS, I'm ready to make mine last about 350000 miles....I keep hearing "with proper maintenance" though...so what would you recommend is the proper maintenance that I must do to keep the car running that long? Does your engine sorta some too pulsate throughout the car when you're stopped and idling? How many RPMs should the car be idling at anyway?
#1622 of 2081 Long Term LS Care
Jul 17, 2005 (2:07 pm)
As many of you know (through many of my stories) I've had a 1st Generation LS since 1992. It doesn't require too much care. I think the only thing one needs to keep track of is the Power Steering Pump. Make sure the fluid is changed regularly. When started the car should be around 1200 RPM. Once it has been running for a few minutes mine normally goes down to 800 RPM. This occurs unless the A/C is on. Also you may have to replace shocks and suspension bushings.
As per your pulsation problem, it may be broken engine mounts. This happened on my 92 after it was damaged in a side impact accident. I encountered some of the same symptoms that you have reported. There was a notable vibration when the engine was running. You could feel it throughout the car. Also there was a buzzing sound from the engine compartment. It is a costly repair at the Lexus dealer so you may want to find a good independant service center to do the work for you, if this is the problem. I think any competent mechanic ought to be able to tell you if this is in fact the problem.
#1623 of 2081 stiff steering wheel
Jul 17, 2005 (7:18 pm)
I notice that the steering wheel on the 2005 LS 430 is stiffer than other cars I drive, for instance the 2003 Avalon and the 1994 Infiniti. Is this in the nature of the vehicle or can it be adjusted? Thanks for your replies.
#1624 of 2081 switching wheel sizes
Jul 17, 2005 (7:21 pm)
If a 2005 LS 430 comes with 18 inch wheels, can I have the dealer replace them with 17 inch wheels, or is the wheel size somehow integrated with other aspects of the vehicle so as to make this impossible or problemmatic? Thanks for your replies.

Ok well, thats the first bit of info I've recieved on that problem....however, my car has never been in an accident. So is there anything else that could cause that? Also I don't hear any buzzing. Is this something that is ok to ignore? If thats all it is....I can get used to it, just as long as it isn't damaging the engine.
#1626 of 2081 Nakamichi sound system.....
Jul 21, 2005 (11:42 am)
does anyone know much about the amplifier and speakers used in these systems. I just bought a 1999 GS 400 (with 56K miles) on EBay with the Nakamichi system. I was going to listen to it for a few weeks before I do anything but I plan to gut the whole system and install my own head unit, amp, components and sub. I was just wondering if anyone knew more about the Nakamichi system or had done any upgrades themselves.

#1628 of 2081 answering the question what is proper maintence
Jul 21, 2005 (8:02 pm)
Proper maintenance is changing the oil at around 5k mikes some people still that it has to be changed at 3k the oils in the last few years have been improved greatly. In fact you can go up to 7500 miles on standard oil if you drive it at least 10 miles a day in one direction. It takes about 7-10 miles to completely filter all the oil in the engine, some people only drive a couple miles a day and never get the moistcher from the engine this causes sludge. So if you only drive a 2-3 miles a day it's recommended to change oil at 3k mikes or 3-4 four months to keep down sludge. A lot of people are now going to synthetic oil which can be changed at 10k or even higher with the new mobil 1 extended oil which says the oil can be changed at 15k miles. There is small down side to this is that all cars will consume at least one quart of oil in 10k miles. The Lexus has a warning light that come on when you are about 1/2 quart low on oil a safety factor built in the car. Transmission oil changes it is recommended you should change it every 20-25 thousand miles. I have synthetic transmission oil in my trans and its seems to work just fine I change it every 35-40 thousand miles. Also change your power steering fluid every 25 thousand miles the quick lube places can some time change for you or use a independent garage to this work. Least but last change the oil in the rear end I would have the dealer do this some rear drives require special oil. The lexus LS400/LS430 is the finest car that can be bought anywhere on this planet. One last thing don't forget the antifreeze every 2 years have any good radiator shop back flush the radiator.
