Lexus LS400 Problems

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 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...

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.

You should not be afraid of buying one IF you are armed with knowing what to lookout for. Timing belt+water pump replacement history is a must . Maintenence records are crucial ..

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.

GREAT CAR, BUT HIGH COST TO OWN
