This is my 4th Toyota and this is the first time that I have ever had anything like this happen. The undercarriage liners and the wheel liners are falling off. Currently I have the liners held on with zip ties. The liners in the wheel wells are gone and I just don't have the money to replace them at $92.00 a piece for plastic. Toyota didn't know what I was talking about when I called them and the dealer said they would repair them for the above mentioned price (not including labor costs)
