there is no poll. try again with a poll at the top. The mod should delete this thread, and you should make a nifty one with a poll
i correct myself. When i first clicked on the post, there was no poll. my bad

Isn't failure related to miles driven? I feel like we're missing some important stuff here!
and what do we count as failure - height sensor(s), globe(s), piston accumulator, pump, motor, shock(s), etc...
regardless of the miles or component that failed or any other details the raw numbers are still interesting.

Thanks for the clarification. And now we already see a problem in data gathering as the poll only lets each person vote once and obviously a person can own two AHC equipped trucks.
Is it possible to get someone you know on the board to serve as a proxy and vote for your other AHC truck?
Thanks

Agreed. Next step might be to do a complete data gathering effort to compile things like:
- Year model
- Miles
- Component(s) failed and at what mileage
- How much "wheeling" done (which might be tough to define)
- ???
That's why I started the first thread, to get some feedback before we started, but some folks got a little impatient. Admittedly, I let them influence me, and that's my fault.
to put in my $.02; problems are not related to miles driven! My 2006 LX470 had the whole spheres and pumps replaced back around 5k miles. then shpheres only replaced back around 20K. been problem free now 77K miles. but have no real faith in them will rip out as soon as I can get to slee"s shop. By the way my 99 LX470 had no issues its entire life up to 90K miles. For some other info in 2006 toyota used a different manufacturer for the AHC parts other then denso.
I own a 2003 LX470 with 120k miles
Mine has the AHC lift on it done by myself. The rear AHC was completely replaced under warranty by lexus at 60k. My front left seems like there is a little dark spot from possibly a slight fluid leak from a bad seal but it has held up well so far and it doesnt lose height at all...I have also replaced my AHC fluid recently at 120k just to be a little more cautious.

For what it is worth, bought a really pristine stock 2002 lx 470 in summer of 2012 with the ahc. I asked the warranty guy at the dealer about the failures of the ahc. He said they were pretty good in the 100's. Hard to pull one over on an insurance company. As a comparison, a 2006/2007 land rover warranty with 50K miles was 3/4 times more expensive with high failure rates for their version of the ahc, from $2000 to $6000-$8000.

That's because with the Rover, the question is not "if it fails" but "when it fails". Everyone I know that had one had their active suspension system fail, one corner and then another, and another, etc. with repairs costing about $1k a corner, as I remember being told. And by the way, basically no body had 200k mi on an Rover without said failure !! Ha !
AHC update
2000 has worked perfectly for the 20K miles since I have owned it and has 177K miles daily driver. fluid changed (it really needed it) per the FSM and the forum here. PO's never did anything and hardly any lexus history.

My AHC was not a real failure as the poll ws limited.
My AHC had issues keeping a full BIOR rear bumper with tire swingout and jerry can swingout...holding a 48" Hi Lift and a 90lb Nitto Trail Grappler tire.....along with a full 3 hoop BIOR front bumper and a 12k LB Titan Winch stuffed inside up front. It would have to readjust under heavy braking, or while being parked for extended periods of time.
Still rode good....but was having issues with the significant weight hanging off both ends of vehicle....plus a set of heavy White Knuckle Offroad sliders in the middle of body.
So mine was not an AHC failure...I just exceeded the units rated capability with modifications.

After reading many mud threads I decided to service my AHC & replace the dampers as mine looked like battered beaten metal pipes, problem was I didn't really know what I was doing and after my second attempt at removing the dampers, the AHC motor packed up... I had already ordered the new dampers and found a used motor, my bulbs & sensors were good, so I just installed new motor & dampers (another mission, ESP on the rear dampers) then I had to take it to the stealer ship for resetting... All in about $2500 and if it happens again I will rip it out, as I am wanting to make up sliders but there is not a lot of space underneath
Oh that happened on about 285k km

Pipes looked like beaten up metal? Does not sound like a "Mall" cruiser
. If you voted yes on failure then this threads results don't mean much. Anything can be broken!

Naa was the owners vehicle for a big construction company and he used to visit 12 sites a week and clocked about 100k a year just working. So came standard to me at 250k and had plenty fine dust in all the right places, but was serviced every 5k and really looked after, so I booked it about 6 months before he sold it
Thanks for clearing up what the 100 went through.
What counts as a "failure" vs. maintenance?
E.g. my tires need replacing regularly somewhere between 15K and 30K but, unless I have a sudden and unexpected blowout I call that maintenance.
I have had to replace parts on AHC, namely the globes and sensors, but nothing affecting drivability...only comfort.
Personally I would call a globe replacement definitely maintenance...those are a wear item exactly the safe as shocks (dampers). Sensors I would probably not consider a traditional wear item although they do need replacement; they fail about the same time oxygen sensors do (~80-120k miles).
