NHTSA Complaint #11569324 — 2021 TOYOTA COROLLA

The rear back up camera continues to adhered road salt and sand debris that blocks the camera's ability to project a clear view in the dashboard monitor every winter season here in upstate New York from early November through last snow in Spring (April-May). I addressed with Toyota office ( I 800-331-4331) at least four times and told to go back to the area Toyota dealer as I previously had done that previous 3 years. I get strange looks as to why their going to resolve this safety concern as the maintenance manual on page 240 of the owner's manual states on right top page,: "If dirt or foreign matter ( such as drooletsz,snow, mud etc.) is adhering to the camera, it cannot transmit a clear image. In this case, flush with a large quantity of water and wipe the camera lens clean with a soft and wet cloth." This cleaning procedure doesn't work in subfreezing temperatures and only causes the water to freeze to this area of the rear hatch area and to the floor or driveway! This is a serious safety flaw having to rely on a dirty camera monitor when backing up which every time I leave my single lane driveway going directly to the avenue I reside. Besides with water and wet soft cloth leaving road grit debris on the camera will further risk to scratching up the view lense cover! So where's the safe solution to this repeated issue every winter now for the 3rd year?
