After driving the car, my car always lowered a small amount. Over the last week, my rear will lower dramatically (sometimes 5 or 10 minutes after parking - sometimes sooner). The car rides fine and suspension rises to normal height when the engine is running. What should I be looking for? I've read about dump valves, and understand that the air shocks can leak. It just seems odd that both rear shocks should fail at the same time. Thanks for your help. . .

Just finished driving, parked the car and it took nearly an hour for the air suspension to "deflate".

Try turning off the system while it's inflated. If it still falls, you have a leak. If it stays inflated its a problem with the system, probably valves.

I'm going through the exact same thing for a couple weeks now. I have another thread started on the topic--- "stock air suspension problems"---

That's why you should search the forum first.

I had a code come up for alternator circuit, but that might have been b/c the car wasn't running. As in my thread, someone mentioned the heat and the height sensors. Mine went down when it was over 95* and humid. It hasn't gone down in a few days, it's only been 88*-90* this week.
I did change my positive battery cable, dont know if that did anything????????
