to my car, all of a sudden, going into "sport" shock mode. It's been working fine on "touring" mode for years. Haven't replaced struts or done anything to the adjusters. Just woke up this morning and "sport". Search seems to show that the parking brake puts the car into "sport" mode. Could it be that the adjustable shock control unit thinks the parking break is on? Where is this control unit? Could it have gone belly-up? Anybody?
