could driving in rain (not even heavy) cause the traction control sensor damage

What is your question?

2016 4x4 chevy Tahoe- stabiltrak service light light first came on driving on highway... took to dealership they are saying it is wet and damaged.. first they thought i had driven in high water, they also said my back break pad was broke by gravel and also needed replaced, I have not driven off road or in high water or in gravel... this was all out of the blue. No previous issues with this other than an unkown bogging down and loud noise when the 4wh drive switch had apperared to be stuck but they found no issues. it now has 55k miles, bought it new, get regular oil changes and tire rotations at the dealership.

What makes this problem better or worse?
