Frame And Members problems of the 2007 Chrysler Pacifica

Upon fast acceleration or braking there was a noticable mechanical "clunk" and a shift forward or back in weight/momentum. This was due to two broken/defective motor mounts discovered during the course of a 64,000 mile service maintenance check. Shortly after dropping the car off for service on 2/17/11 I received a call form the dealer alerting me to the fact that when the accelerator is pressed the engine would rise to within two inches of the interior of the hood. The dealer replaced the mounts and showed me the bad parts and explained why they fail and drain their liquid filler. Althouth my car is well out of warranty I contacted Chrysler to ask them to cover the cost of the repair and they told me that this was typical mechanical wear and tear on the vehicle and is not covered in or out of warranty. I personally view this as defective parts and engineering. I have owned many cars over the years and have not had to replace a motor mount. Further I simply went on to the internet and googled "motor mounts 2007 Pacifica" and came up with many, many cases of the same probelms with Pacifica's. I cannot speak to the issue of direct safety issues with this problem but surely with a motor improperly secured the potential for danger is paramount.

The vehicle has 37,000 miles on it. According to the dealership, the rear motor mount is broken and needs to be replaced. I find it hard to believe that a motor mount would break at under 40,000 miles.
