Touchy, maybe?

It's going to be an as you say a "crap truck" until you discover the possible causes, all of which are described with fixes starting with the original post.

I'm surprised you haven't seen a mechanic, especially with your wife and 2 children involved.

Not sure you can file a viable lawsuit, I'd work on the English language for a bit. But in this country you can sue anybody for anything at any time.

Please let us all know what you mechanic says is causing the scary driving.

Forget about working on English unless you are dreaming to live at Buckingham palace. My point as an engineer is if a car is designed with so many controls then wear and tear of mechanical systems triggering controls to put occupants at risk makes no sense.and then you suggesting to fix one part after the other part just to get controls communicate with each other. Its waste of time and money for me while lexus and mechanics make money...

He is right, Semi-tractors air brakes are designed to lock up the brakes of the rig in case of catastrophic failure preventing a runaway big rig. Theses trucks should not have unfettered access to the braking and steering systems and suspension systems if they're gonna go Hal-9000 and sac the family of 4 instead of just shutting the systems down and behaving and a far more predictable way simply because it gets some extra resistance from old sensors or trouble codes form 3200$ braking units or 3000$ worth of suspension parts.the computer should just default to the lowest height setting and maybe remove abs not activate brakes and lower corners all ***** nilly in reality the way that works is dangerous and these parts should have been recalled and been given an option of replacing these systems with safer more traditional ones.

i have 01 LX470 with 190k miles...i had same issue as most....no need to even take it to mechanic....just inflate all tires to same pressure , i did 39...and bingo....all lights disappear !!!...i recommend put all 4 new tires.. which i did and trust me suv looks cool with big tread tires...worth it....best suv designed ever !!

I think this is the single biggest change in opinion of a vehicle on any forum ever. lol Glad you got sorted and for so cheap, but keep an eye on things, it's possible it just hasn't showed back up and the tire pressures are coincidental. It dos make sense tho, a tire with less pressure would read smaller to a sensor and think there's a discrepancy.

Hi everyone I’ve been reading everybody’s comments and without getting right into it my 2003 Alex for 70 was taken down to have a wheel alignment done and my steering wheel was not centred so they sent it after that same thing the car pulls to the left it’s gotten worse and worse and now is undrivable I’ve had it to the Lexus dealer and because it doesn’t show up on the computer when I plug it in no one knows what to do with it I’ve now got it at home and Alex is dealers three hours away so I took it to Toyota they don’t know what’s wrong with it either so I’m now stuck with a car that no one can tell me how to fix it I’m wondering if anybody has any solutions or how they fix there’s

cheapass

Well, if it's pulling that bad there's either a suspension/chassis issue or the brake is grabbing you gotta figure out why, if the steering wheel wasn't centered then there could be an issue with the assisted steering. Make sure all 4 tires are the same, these vehicle like their stock tires, make sure all the sensors are good (take it to an automotive electrician who either specializes in lexus (these lexus') or has experience with them but either way, make sure the brakes aren't just mechanically seizing, make sure the master cylinder/abs system isn't malfunctioning (automotive electrician) I say take it to an automotive electrician because they are generally better at diagnosing electrical systems which these particular SUV's tend to have issues with old sensors/wires/ that expensive M/C, and an auto elec specialist will have more experience tracking down issues like the ones these suv's typically have. Sounds to me like you have a bunch of techs who are too lazy to trace the issue back to the source.Hope that helps.

I'd get on the Lexus Australia website and call Lexus. They'll open a "case" for you. Let them know what you're going through. They'll find a specialist in Australia who will know a LOT more than a dealer.


Plenty of 200 series running on non-stock tires...both non-oem manufacturers and well as tire sizes.

An "automotive electrician" will be useless without prior Toyota/Lexus experience and Toyota software...e.g., no way to check the ABS system or bleed it without TIS.

I had the exact sample issue with my 2000 LX470. I had the Rack (rack and pinion) replaced and it solved the problem completely. No sensor issues or VSC alarms. It has been over 5 months with no problems.

cheapass

Do you just take your car to any schmoob with a fancy sign? Of course you would inquire into the specialists abilities, but you don't need tech stream to use a multi-meter and I'm willing to bet any simpleton who's been doing the electrical and only electrical in a car day in and out for many years would be able to find issues that fancy scan tools can miss,and because your multi-meter works the same on every car they can do it a lot quicker than you seem to realize. But thank you for your input.

hankinid

Appropriate user name.

You WILL need TIS to diagnose OP's issues...unless OP enjoys throwing parts at the truck until something works. VSC issues cannot be diagnosed with a multi-meter...I'd bet you haven't read a shop manual with info relative to Toyota VSC. Read post #46 and educate yourself.

Thanks for nonsense.

cheapass

25 years working on everything under the sun has educated me, bi directional testing,ecu reprogramming, and fluid pressures are the only things you're gonna get from the tis in this situation that you aren't gonna get from a multi meter and while those are useful I know of 3 excellent electricians in my area who have been at it for 30-50 years and I would pay them before any toyota tech with tis because they will tell you what wire,resistor,diode,sensor, capacitor is bad instead of simply saying "you need a new this or that" and in most cases they'll do it within the hour. Again thanks for your input, but I don't need to be told to follow the herd, and I don't generally listen to anyone who tells me I'm wrong when my own personal experiences tell me otherwise. You are talking about computer controlled hydraulics, and while the hydraulics do fail without proper maintenance the vast majority of everybody ignores the electrical because it's a pain in the *** to tend to and most automotive technicians are plain terrible at electrical because in most applications they don't have to mess with it. The OP can do what they want, they can buy a cheap laptop get the obdII cable pay for a day of tech stream IDGAF but do not tell me that I can't diagnose these issues without a FSM or TIS. You're like the idiot trying to tell the master what the master can't do. The multi meter can track ALL electrical issues if you know how to use it properly ALL of them. And EVERY electrical system follows the same basic principles, so while you can trust a novice with the toyota specialty scan tool or a laptop with techstream, you can also trust a master electrician to find out what's actually causing the issue instead of simply what part/s could be bad. Good day sir, try to educate yourself.

cheapass

oh look Scotty kilmer even mentions how an 80$ multi-meter is a valid substitute for his 3500$ scan tool. Please enlighten further oh Guru of the forums... your wisdom so deep and your knowledge so great. skip to 1:20 or so to hear him tell you pretty much what I did.
