2012 Toyota Highlander wipers, windshield & visibility problems

Tl* the contact owns a 2012 toyota highlander. The contact stated that while driving approximately 35 MPH and steering to the right, the engine suddenly emitted an abnormal noise. The contact also stated that the headlights would not shut off intermittently when powering off the vehicle. In addition, the defroster for the rear window would not function properly, causing the windows to remain foggy for a long period of time.

My passenger side sun visor broke internally and the internal spring forced it to point straight down. It blocked the driver's view of vehicles approaching from a side street on the right . I have fiddled with it and got it to stay up about 3 inches from the roof , but it keeps creeping back down . I ordered a replacement sun visor from toyota through my local toyota dealership in january . The order was "back ordered" and has yet to be shipped from ( I presume ) south east toyota distributors .
