Why no adjustable height suspension?

LX470s all have AHC (auto height control). My '06 needed an accumulator repaired, to the tune of $2000 installed. That was just one of three onboard. No thanks.

Did this for my stepdad. At my discount (no labor for him) 4 accumulator pods and 2 pints special Toyota AHC Fluid cost him close to $2500. The job is easily in the $4k+ range with labor and customer priced parts and it has to be done with a scantool (usually the accumulators start to fail close to each other from what I learned.) That's the "common" failure of the AHC system. Not to mention Toyota is finicky about letting you stay in anything but normal height for too long.

Because the 4runner isn't a luxury SUV. It's marketed primarily as a rugged, simple, reliable vehicle. Adjustable suspension is pretty gimmicky, IMO....if you find yourself often needing additional ground clearance, put on a static lift and be done with it.

On a related note, I've played with the adjustable suspension on my mom's JGC - the tallest height setting only stays at that height until you hit 30km/h, and the second tallest deflates at 60km/h. After that, you're locked in "aero" mode for anything faster. It's kind of a pain in the ass for driving in deep snow when you want the ground clearance and also need the speed.
