Recently, we purchased our new CX-7. The vehicle had been sitting for a couple of weeks outside on the lot with close proximity to a field. After about 300 miles, I noticed that the insulation on the plastic shield below engine compartment was half gone. Apparently, upon closer inspection, this was the result of a small field mouse. As I believed the problem to be one encountered at the dealership, I informed them and they agreed to provide me a new engine shield at dealer cost . . . $187.00. Now the big question, what is the purpose of the insulation and how in the world does a plastic shield cost $187.00. Unfortunately, the cost is not covered by warranty. Any thoughts?
