2010 Toyota RAV4 wipers, windshield & visibility problems

I purchased a 2010 toyota rav4 january 2010. Living in maine, winter driving is unavoidable. My complaint is about the rear windshield wiper, which is designed to clear the window from the driver's side to the passenger side. Unfortunately, the snow gets trapped by the mounted spare tire and stops the blade. To clear the rear window, I have to exit the car and manually clear out the snow, which does not solve the problem when it continues to snow.

The contact owns a 2010 Toyota RAV4. The contact stated while driving at an undisclosed speed, the moon roof glass fractured without impact. The local dealer was contacted and an appointment was scheduled. The vehicle was not yet diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 187,000.
