Per the Toyota service department, the drain hose for the air conditioning condenser in my 2013 Toyota Avalon may become clogged causing water to accumulate at the bottom of the air conditioning condenser unit housing. The accumulated water may then leak through a seam in the housing onto the air bag control module potentially resulting in a short circuit of the module. They say Toyota will not fix this problem.
I am writing about my 2013 Toyota Avalon, there is one really bad design flaw!!! the accent chrome around the controls and air conditioner vents reflect the sunlight into the eyes of the driver and front passenger, and it is blinding. The blinding reflection may cause accidents and/or direct injury to the eyes such as retina, cornea damage as well as any other eye damage as a result of bright sunlight. I have tried the darkest/protective eyewear that I can purchase but the reflection still comes through blinding. I have also had the darkest window tent allowed by law installed (purchased at the dealership). I have contacted the dealership and Toyota directly but have had no offer for a solution. This is a simple to fix with a replacement piece of dash chrome in a non-reflective color such as a flat black, wood-grain, or brushed metal color. A custom designed dash area shade should also offer a solution. I have verified that there have been many other complaints through an internet search.
