It started out with the esc light and abs lights on. The dealer told me it wouldnt hurt my vehicle but it would fix the lights if I paid 2100. Now whenever it rains, the 4 wheel drive light comes on and the vehicle will make loud noises and shake. Could it be the anti lock brake system causing the 4 wheel drive malfunction?? Right now it happens randomly, but usually when I encounter rain covered roads, and will eventually go off. The other day the steering wheel seemed to lock up, and it was hard to turn.
