2017 Toyota Tacoma water leak in cab on back head liner

water damage inside cab on head liner across upper back head liner. Out of warranty due to mileage over 36000. Its my husbands truck and this is his 2nd Toyota. Dealership may cover repair but possibly not the replacement of interior. Waiting to hear from dealership. Toyota Company said No, they will not help out with cost. This is a repeated problem with their vehicles yet they don't want to take responsibility for faulty seals or gaskets which ever may be the case. I have done a little running back and forth and making calls, sitting on the phone waiting to find who is will to help. Stressed and no funds to protect our auto investment.
