Since going through automatic car wash sunroof leaks water now even when it rains. Took to dealer and want to charge me several hundred dollars to replace seal. Did investigation on internet and Mazda has a service bulletin stating this is a problem with certain vins which mine is included and is covered under warranty. Going to call my dealership now and see what they have to say.
