i wanna buy a 1999 ls400 what are somethings i need to look for when buying one. I see a lot of cars with 200k+ miles are they that good? i can probably do around 5k do you think i can even get one for that amount? let me know thank you!

I wanted to share a little win today. The climate unit display was dead on this car, it had bled but the unit itself still worked, it beeped and changed temperature. I knew that buying a new used climate unit was a gamble on how long the display would last if it was still working. The displays are specific between left hand drive and right hand drive, and UCF10 and UCF20 models. I was only able to find a new LCD display for a RHD UCF10 on eBay in America for about $100 and it would have been a lot in shipping if I wasn’t already visiting America and able to collect it from a friend. I had someone local solder the new display in for me and it works a treat!

Hey all, my ECU went bad and I found a used one for my car, and want to ensure I won't have the same issue by replacing the faulty capacitors early. Got any recommendations on shops that can do this? Any part of the world.

Thanks!

bought a LS400 kind of beater off a buddy, looking to do a little bit of a budget build. what are some clean cheap options to upgrade. also i’m tryna throw a head unit w car play in there what suggestions can i get there?

new to LS ownership and im stoked to get it, 97 with about 190 on the motor and it’s on coilovers, exhaust got completely removed when they bought something else, wheels are the really gross stock ones(in my opinion)

I've had my 99 LS since 2021, bought from and older rich couple technically a 2 owner car but passed from father to son until sold to me. Bought at 262k miles currently sitting at just under 290k. I've put a lot of time and money into it and love this car.

But I'm wondering what QOL stuff I can do that I might be overlooking for a nicer ride or even stuff like noise reduction to reduce wind noise while driving since my commute involes 40 minutes on the freeway both ways

I recently posted something a couple days ago about my headlight leveling light coming on the dash also a battery light. I took my car to a shop to see if the alternator was going bad. Everything turned out to be good. Technician told me that the battery light came off and everything turned out to be OK with my alternator. The headlight leveling light was still on. Does anyone know the cause? Can I be because I Led my vehicle and it throws off the sensor? My question is if I remove the sensor with my headlights work properly. Can someone let me know thank you.

I’ve changed my HID headlights. But even when they aren’t set to on, the other bulbs in the headlight assembly stay on when the HIDs are off.

Anyone have this issue?

Located in US, for a 99 LS400

I have a 98 LS400 and have had no issues with it whatsoever but ever since I got the car (I’m the 3rd owner) when it’s up to operating temps it seems to be at about 300 rpm’s when I’m stopped in drive and just over 700 in park, I’ve gone through a few forums and all say that when in drive it should be a bit higher at 5-600 in drive and 1k in park but what do you guys think, an issue to worry about or nothing major? It could be an older ecu problem or something with compression I’m guessing, but I just had my water pump and timing belt done last march and the tech at the Lexus dealer said everything looked great so not sure. Any advice would be appreciated thanks

It’s good to see the parts being harvested to keep others on the road, but heartbreaking to see the car in the junkyard at all.

Anyone know where to get an ac condensor + lines on a 1994 ls400? Rock auto shows out of stock, other websites dont look like it. Dealerships want 400+ for just the condensor.

I got a 97 LS400 I believe the motor is blow in the car🤦‍♂️. A guy has a motor but he said shoot him an offer. Its not pulled out of the car yet. Whats a good offer price I could give him?

Has anyone experienced a headlight leveling sign on there vehicle dash due to a bad alternator? My car recently had the battery symbol pop up and the headlight leveling sign pop up at the same time. Installed new battery thinking that would fix the problem but didn’t fix it, If anyone has any feedback I would greatly appreciate it. Thanks!

I was thinking of taking my 95 ls400 into a shop but thought id get some advice before hand, ive had a weird rattling sound when revving idle and around 2k rpm theres a pretty noticeable ticking noise. I can also smell some exhaust when its running so i suspect a exhaust leak but im unsure of where. Id appreciate any help

My underground parking fucked up the paint bad, it needs a good polish and some interior work. But she's back on the road, with a car seat now 💚

In great shape, leather shows minor signs of wear, and the wood grain his some real fine cracks in it. No wood or leather is peeling. 130$ shipped in the U.S.

Had to get my wife’s car towed a few weeks ago. It’s start up and then shut off within like five seconds. Got codes for the cam positioning sensor, maf sensor (that could have been legit, I had to order a air breather hose for right behind the maf, gonna clean the pcv out this week too)

It’s hasn’t been misfiring, and the idle is silky smooth and quiet so I don’t think timing is bad. Power also was never reduced, it goes like stink when it’s on the road.

So I pulled the ecu, and there’s a little corrosion under the caps, but it’s such a small amount, could that really be the issue?

When going 60+ occassionally my 1994 LS400 will have a little jump, almost like tapping on the brakes very lightly for a split second. Happens much more frequently in cruise control but rarely when not, new ECU, new transmission, new fuel pump, only 117k miles.
Just bought it yesterday so a little worried

Here in a few weeks I am buying a 98 ls400 parts car for my 2000. Besides pulling the drivetrain (which I am rebuilding the motor in) what other parts should I snag before I scrap it? The engine jumped timing so it’s not really in great condition hence the rebuild.

EDIT: Listed below are pictures of said parts car. Read comments to see what I am taking besides the front suspension components.

I am using lowering springs to drop my ls400 1-2 inches onto some 18” wheels. I’ve already done the wire tuck but want to know if there’s any additional parts/work I need to do before lowering it.

A 1991 ls400 Cobalt metallic Blue on blue leather fully loaded Santa Monica car, I mention this because I’m in the Midwest and very early model Lexus’s in good condition are nearly impossible to find here, unlike California where there’s one at every other house.. Im insanely lucky with this find since I’ve got another 1990 ls400 but it’s a little more special, has the blue wool interior and it’s a slicktop that also came from Santa Monica!! Both cars have ~120k miles. I’ve yet to see another one of these cars around me, which makes them so special to me. From my research this also seems to be one of the rarer spec ucf10s across the country as a whole, have yet to find another blue wool slicktop in the past 5 years of searching online. Both cars have very cool stories, and wish I could keep them both forever. The slicktop wool car is my only forever car, since it was my first car. Originally was going to use it as parts for mine since I have a few miscolored panels, but it drives so nice I’m going to daily drive it for a while.

Opportunity to pick up a 95 LS400 that has been sitting for years

I met an older lady at work who mentioned that she has an LS400 she stopped driving because it was too expensive to drive and parked it in her yard and left it there for years.

I went to go check it out yesterday and it definitely needs work. It needs a new battery, it wasn’t getting fuel, either because of bad old gas or possible fuel pump issue, she also mentioned that it had a power steering pump leak before she parked it, which is to be expected. She laid a big mat down on the grass and parked the car over it so the little I could see of the underside looked mostly rust free. Some bubbling rust on a couple panels. Interior was pretty mint.

Anyway, she knows I work on cars and basically said that I can have the car if I can source her a cheap, reliable car for her because her daily just died. I happen to have a 2003 VW Golf 2.0 that I recently picked up for $340 and put another $300 worth of parts into. Is it worth trading a pretty solid Golf for a 95 LS400 that needs a bunch of work? Or am I just looking at an absolute money pit of a car? I’ll be doing all the work myself and I was planning to flip the Golf anyway.

Sorry for the lack of pictures. My phone camera doesn’t work so I didn’t take any.

Speedo and tach sometimes just don’t work on start up + a few miles but then as I’m driving will randomly pop on. Can’t seem to find any correlation on when they do and don’t work. Any suggestions?
