Thank you tecman I already sent it. And I also want to contact directly the Lexus Headquaters in Japan. I think it's not fair using that trick to avoid payments for an issue that Lexus acknowledged as a manufacture problem.
Does anyone have any idea how I should tackle my situation? (With the code being stored in history etc.) Ideally, I'd still want Lexus to look into the secondary air intake, otherwise I would have to chance it and hope something either goes wrong before the 10 year, or nothing at all....
This member had some challenges getting reimbursement for his GX for warranty repair in the UK. He is in the military. He did eventually get reimbursed.

I ran a known VIN from a '12 Canadian GX 460 I still had a record of and it only showed the airbag recall
You may want to consider one of the bypass options.
There was a warranty for the 10-13 GX460. However, it was only for 48 months or 80,000 km.
The CanadianTSB for this is now expired and there are only 2 other service bulletins for your year/model. Once for floor mats and the other the immobilizer and smart key.
Aside from a recall like @ Acrad35751 found there is nothing else. Give us a call and we would be glad to help you with a solution.

I'm new to Club Lexus (and Lexus, in general) and recently picked up a 2010 GX with 49k miles on it. I hope to become an active member of the forum and provide valuable contributions. Today, unfortunately, I just have a question.
On Saturday, I took the car through an automated car wash. I normally do it by hand, but once a year, as winter ends, I take it through to get the undercarriage sprayed. It's a car wash I've used 50+ times.
About a mile after exiting the car wash, I got a CEL, followed by the Master Warning Light, 4Lo, AFS, Low Oil Pressure, and High Automatic Transmission Fluid Temp. After about 5 seconds, the engine shut off and came to a halt, along with loss of power steering and power braking. Luckily, I was on a side street. About 30 seconds before, I had been on a busy 4 lane road.
tried restarting.... it cranked but wouldn't start. About 45 minutes later, the tow truck driver got it running for about 2 seconds, and then it stalled again. It spent the weekend at the dealer. I'm waiting for them to give me the codes, but they said they started and ran it with no problems today (so far, they seem to be playing dumb).
I think / thought it's not mechanical since the warning lights are all over the place (e.g., 4Lo and adaptive lights), but then I landed here and have done much more digging since on the secondary air injection pump and water intrusion.
My questions for the group are:
- Has anyone else experienced anything similar following a car wash?
- Specifically, has anyone had their engine cut out? I've read a lot about the car basically going into Limp mode, but I haven't come across anything yet about people's engines shutting off completely.
Any insights are greatly appreciated. Again, I realize I don't have codes to share yet, and that's a material detail.
afig36: That is odd behavior as I don't recollect air pump ever causing a stall out. Limp mode yes but not issues related to starting. It sounds like water got into something electrical. I have also not seen an issue trigger the Low Oil Pressure or High AT indicators. Any water leaking around the windshield into dash area?
There was a little bit of water in the passenger foot well. I'll report back tomorrow with the codes. Dealer said they weren't able to look at it today because I didn't have an appointment. I have my A3, so it's no big deal to wait another day.
I asked them to lift a new GX up alongside of mine and see if there's anything missing or any differences.
Got the car back today. It had nothing to do with the Secondary Air Injection System, but I'll close the loop in this thread since I brought it up here. Note that this just shows what the results were, not what caused it to begin with:
U0100: U0100 is a serious situation where the signals between the electronic control module (ECM) or the powertrain control module (PCM) and a particular module have been lost.
B15BB: Loss of connection with the navigation unit.
Dealer ran it through the wash several times and couldn't duplicate the problem (surprise!). I didn't get a straight answer on whether they were using undercarriage sprayers or not. They checked all the wires and didn't see anything loose or exposed.
None of this is reassuring, of course, but no more undercarriage washes for me. I may look into installing a front skid plate to just better shield the engine from puddles, etc.
For more that a year now, the check engine, slip indicator and 4Lo lights are on for my Lexus GX 460. Initially driving was normal and you will not notice any problem. Recently how,when the check engine light begins to blink, the car cannot accelerate beyond 80km/h. I have try several diagnosis,where the scanner is placed on the vehicle's computerized system. Sometimes, when these lights clear, within one hour drive, they reappear. What can be the problem?
