Fabric seats
 The fabric seats/console between the seats water stain. Toyota will not acknowledge it as a manufacturers defect which would be covered under warranty.  Their solution is bring it in and get it detailed which will not solve the problem.   My car is 6 months old and the interior seats/console look awful.  Nothing spilled on the seats except water/condensation from a water bottle. This is outrageous.  Clothing does not water stain except for  delicate silk that requires dry cleaning. how could Toyota believe that car seats that water stain are acceptable.  I am truly disappointed in their response to date.
