I'm in the market for a 08/09 for my wife, do all years are equipped with air ride? whats the most single component of the suspension to check for that the air ride is working properly? like sagging or not level all 4 corners, thanks for a any help, I didn't see anything in the stickies about it.

The rear suspension has airbags in lieu of coil spring, used for leveling not necessarily a quality of ride. If they are leaking thevehicle will sag. It will be sitting on the axles jounce protectors

I would say the air bags are the most common failure around 100k miles. It can be kind of hard to determine if they are leaking. The rear of my car would not deflate all of the time. Sometimes it would stay inflated all day.. some days it would deflate while I ran in to grab a coffee. Luckily, you can source your own parts for about $300 and the installation is relatively easy.

You can check the air pump and rear height sensors for operation by simply adjusting the height switch on the console to the High/Low postions.
