Superior customer service is a top priority at FASS. We expect every FASS System to exceed your expectation. Customer satisfaction, your satisfaction, is the all-important ingredient for success to our business.
 
Normally, technical issues can be resolved by your dealer’s service department, as they can usually inspect the situation physically. If you’re not satisfied with the dealership’s response you can either email or call FASS.
