What are Common Problems with Lexus LS 400?

Your LS 400. It's one of the most popular Lexus sedans ever made, and for good reason. It's got a legendary reputation for being a pure pleasure to drive. Sought-after as the car is, though, it's not without some issues over the years. Here's a few to look out for, and what to do about them.

Bad Suspensions

When you brake hard or quickly, does the car creak or whine? The trouble's almost always worn suspension parts. This was a known issue for LS 400 models from between 1990 and 2000. It's even more likely with 150,000 miles or more on the odometer. Run an inspection and replace anything the results call for.

Faulty Transmissions

If your LS 400 slows down roughly, the overdrive's no working, and the Check Engine light's lit on the dash, complete with error code P0770, there's a good chance you've got either a bad torque converter or some other transmission problem. This is commonest in models from 1996, 1997, 1998, and 1999, with 100,000 miles or more clocked. An inspection can tell you one way or the other, but if you're not sure what to do, bring the car into a certified Lexus service center; the pros will be glad to take care of things.

Failed Rear Sunshades

Lexus envisioned LS 400 as an ideal combination of reliability and luxury, an enviable grade above the rest. As such, its faults were thankfully few and relatively easy to deal with. One of the few: rear sunshade motor failure. It was a thing for models from between '90 and 2000. This happens, and you'll hear grinding when you run the sunshade, followed by it not working. Replace the assembly, and likely the fuse for it, and you should be good to go.
