1999 Lexus LS400 ProblemsNoise 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.
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.
Owners have reported experiencing rough deceleration, inability to engage overdrive, and a check engine light with diagnostic trouble code P0770. Problems with the torque converter or deferred transmission maintenance can trigger this. Professional transmission diagnosis is recommended to address this issue to prevent unnecessary part replacement and expenditure.

Engine light is on but car runs great.
Any simple solution since no flashing "M" light occurs
I checked the back of my car and when I do everything all my lights works but it still says tail lamp failure.
The low washer fluid warning message flashes nonstop in the dash even when the reservoir is full. The dealership told me it would be several hundred dollars to repair. Is it very difficult to replace on my own or can I "cut the wire" and live without?
