I had the same problem with mine also. Look under your front passenger seat remove the 3 bolts (10mm) holding your radio amplifier in the floor and disconnect wires on the back be patient they are alittle difficult to take off. after you have removed the amp you should see the deck floor, check for water and possible damage to the yaw rate sensor. the yaw rate sensor is directly below the amp you removed also. IF there is a water leak probability is it is coming from the sunroof drains. to fix that problem you must unclog them . Remove your handle grips in the front pillar A covers "near the windshield" and gently pull off covers. BOOM, right there is your sunroof drains. disconnect from the black plastic elbows and clean those also I cut the tips off of them also to help the flow from the drain easier. pour hot water in from your sunroof and it should unclog the drains one on each side. place all back together and make sure to put electrical tape around the drain hose and plastic elbow to insure no water will leak form it again but make sure your elbows are all the way back in. Your welcome and that should save you a couple hundred bucks also if the yaw rate sensor it damaged from water just the PART ALONE is $500.00 only available from the dealer then you have to take it back to the dealer to have them calibrate it. Good luck hope this helped!!!!
