Higher mileage cars can develop creaking and groaning noises in the front suspension, particularly when coming to a quick stop. Inspection and replacement of any worn parts should correct this concern.

Lexus LS400 Problems
The problem was that when coming to a stop, I would get the sensation of letting a manual transmission car stop without engaging the clutch; i.e. a shuttering sensation. The diagnosis was that the shift solenoid "E" encased in the transmission was faulty (PO770). The problem is that this part has been replaced twice within a 12 month period leading me to believe there is something really wrong with the diagnosis, treatment and possibly the t...
Power steering "growling", leaks around P/S pump and white smoke when car is first started in morning.
If your power steering pump is making noises or leaking, get it fixed ASAP or you will likely be replacing your alternator too. The alternator is located right below the P/S pump and if fluid drips into it it will short out the alternator, this has been occured many times.
Also, if you get a puff of white smoke in the morning it may be a bad speed sensitive steering solenoid, which screws into the power steering pump and has a vacuum line ...
Clunking noise coming from rear when stopping and starting. The bushings in my rear carrier arms (I think, it's been awhile since I replaced, crawl under car and find the arm that moves around significantly when pressure is applied) were COMPLETELY worn out, the rubber was missing and the metal housings were just flopping around.
Use aftermarket bushing ADUS 505 (about $35 each, search online) to rebuilt each arm. Repair isn't too bad if...

Update to my previous review Visitor, San Jose, CA, October 30, 2011 13:44
298,500 miles and rising. Original engine and transmission. I just changed the timing belt again (interference engine) and I had to have the crankshaft pulley replaced. Bummer - Still running strong though. I have to milk it though as I just purchased cars for my Wonderful wife and two kids. I recently changed to a high mileage motor oil mixed with Lucas oil stabilizer. I changed because the valves were starting to make a little noise and the extra viscosity helped a bit. I am changing back to a full synthetic (probably Mobil 1) along with the Lucas. This is an excellent combination for this car. I am hoping that I can milk it to 350,000 - 400,000 miles, but wow that is scary. I may have to have the valves tightened up. I would love to do it myself, but 32 valves is a lot of valves ! Good Luck - if you can find a 1997 Lexus LS 400 with low miles and a great price, I say "Go for it" !
Best car ever, brought in 2004 -kept oil change and tune up,and brought new tires; I never had to spend anything thing else on it. It is a ladies car, problem free, next car will definitely be a lexus, had this car going on 9 years, getting brakes put on it this weekend 6/29/13 for the first time. Plan to keep it as long as it holds up, body in good condition,I get compliments on it all the time. Plan on buying a new one next year just because I want a later model car and keep my 99" I will not trade it for anything. I'm Lexus for life.
this car cost Mercedes Benz lead engineer his job! (due to panic decisions) and for good resin, it is better than any Mercedes of the pre-2000 era
Owned this auto for 12 years. Have had 2 problems, most of all it is important to continue to keep maintenance up, which is what I do.
About 3 years ago replaced alternator and battery. Having to replace the starter today on 10-8-12. Overall this is the best auto I have owned. This is a low replacement auto. Runs exceptionally well.
When I do get another auto I want a Lexus.
We have a 1990 ls400, 160k miles, the power steering pump leaks fluid into the alternator causing it to go out. We're replacing both items but, the instrument panel light is going haywire while this is happening. Does anyone know or have had similar issues & did the replacement of the alternator & power steering pump fix the problem with the instrument panel? Thanks for the feed-back.
