came home tonight and parked GL in the garage and within a couple of minutes the front air bags were down, both sides,I can stand there and hear them going down. this is the second time in 2 weeks this has happened. once i start it the air bags go back up. since this isnt happening every time i turn off the vehicle i would think i could eliminate a leak.Dealer wants $125 just to look at it. Was hoping someone may know what could be the problem and how major this could be. I keep hearing nightmares of owners having to pay up to $4000 just to replace the front. Hoping replacing is not what i need.
