Lexus LS400 Problems

Noise From Front Suspension

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.

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 ...

Rear Window Sunshade Fails and Makes Grinding Noise

The motor for the rear window sunshade in the Lexus LS400 is known to fail. When this occurs, the sunshade will not extend over the window, and a grinding noise is heard until the motor fails as well. 

Replacement of the sunshade assembly is necessary to correct this failure, however, removing the fuse for the sunshade will stop the motor from making the irritating grinding noise.

Lexus LS400 Reviews

I purchased this car new and now have 208000 plus miles on it. My wife and I made many trips of over 3000 miles over the years in it,and we never had a single problem. The only money spent on this car has been for normal maintenance and for things that are subject to wearing out, such as batteries, timing belts (2) alignments. and a very few lights. This has been by far the best riding and most...

I've put approximately 75,000 miles on it since purchase, including pulling a heavily loaded trailer from CA to MI in 2013. I still average 24mpg on road trips, and 22 mpg on my daily commute. I purchased my 93 LS400 with 185000 miles in Dec 2011 for $900. It was blowing white smoke, the previous owner had b...
