2005 GX470 p2441 Secondary Air Injection System switch stuck
120K miles - love the car
cel, skid, VSC trac and VSC off lights on - dealer said the code was p2441 Secondary Air Injection System switch stuck
Dealer said I needed to replace air injection system for $3495.00 and that the cel would not go off until it was repaired. They completed the 120K service for $641 and when I picked it up, all the warning lights were off. I have driven it a couple of hunders miles since then and still no lights. Does that mean it could have been something else???? I love the car, but I need tires and brakes and now $3500 more could mean $5K-$6K of repair for a 2005 car with 120K. Looking for advice.

Unless you want to spend almost $3-5K(depending on what dealer you go to).... yes that would be my recommended solution. 
Will it hurt resale, who's to say. If you have money to blow for the dealer to fix it then by all means get it replaced. If you can DIY then that's the route you should go. I live in Florida and we don't have emissions testing but if we did there's NO WAY IN HELL I would pay the dealer that kind of money to replace a system that essentially pumps fresh air into the exhaust for the the cats upon cold start-ups. For that kind of money I'd replace the whole motor and put a LS in it.

Is there any worry if I don't do anything and just drive it for a while?
This car has already cost us almost 5k in other repairs and I hate to throw anymore money at it unless it stops having issues.

What kind of repairs?

P2441 code which you have got - AIR Control Valve stuck close. The following gets disabled.
Now the above are disabled ( Fail / Safe Method activated by the ECM). Becoz of the fault P02441. Running your GX with the above disabled would have your Fuel / Air Ratio becomes very richer, causing in-accurate fuel flow and sometimes Engine stall. Whether it is safe to run the GX. I can't answer that. Well it is not a comfortable drive having these issues around.
- O2 Sensor1
- O2 Sensor ( Air Fuel ) No activity
- O2 Sensor2
- O2 Sensor3
- Fuel System

"What kind of repairs?'
Well we just bought it in February and so far this is what we've had to do.
1. Timing Belt and Water Pump replaced - $1,200.00
2. New Tires - $800.00
3. Replace spark plugs and repair damage to knock sensor wiring (cause by a damn rat) $1,400.00
I know 1 and 2 I would have to do to any car and 3 was just an act of god and totally random. It just feels crappy when we just bought the car and we've paid out so much already. With this $4000.00 dollar repair now I was pretty close to turning the darn thing in and getting something else.
That's why I asked about driving it for a while. If it would not break down for at least 6 months I would feel better about putting more money into it. On paper this thing should be a dream 1 owner old lady always serviced at the dealership. But right now it feels more like a nightmare.

Mine too is a 1 owner, older lady, always serviced it at Lexus (have pages of work done / scheduled maintenance done etc.) and knock on wood it's been great other than the crappy suspension. If you have free time do a google search for Toyota forums, especially about Tundras / Sequoias and you'll see many drive w/ the valves stuck open and close. It only runs when you first start your GX, it doesn't run any other time. It's just used to pump air into the exhaust for the cats. The only reason guys are using the by-pass is to pass their emissions testing. You'll be fine driving your GX but if you live in an emissions state make sure you fix it, use the by-pass module or sell it before it's due for the next test. The last thing you want is a failed emissions on your carfax report.

I really starting to think I've been cursed. So on the way home tonight I slow down for a stop light and come to a complete stop. Then I notice the car next to me is rolling forward only it's not the car next to me... It's me! My brake booster had quit working and I was on manual brakes. I started pumping them and after the 4 or 5 pumps the booster kicked back in the the normal feel of the pedal returned.
'Does anyone know if this is a common occurrence with these cars?
I'm taking it tomorrow to carmax to get a quote on what they would pay me and I've very much considering unloading this thing and being down with Lexus.

If I were you'd I'd be very cautious about driving it. Sound like you need to fix a lot of things or just get rid of the GX money pit.

I even called corporate about the air pump problem and they said they would give me 10% off of the repair. What a joke, I thought Lexus customer service was supposed to be the best in the business. My last car was a 4Runner and I had it for over 10 years without any major issues at all. The only reason I got rid of it was I wanted something a little bigger and I wanted a Lexus.
I'm so disappointed now I'm just not sure what to do.

You should definitely get the brake booster / brakes checked out ASAP! If it went out on you last night you don't want it going out again. Luckily you were at a light stopped, imagine going 60mph+ and needing them and you don't have them.
