Front Suspension Coil Spring problems of the 2006 Chrysler Town & Country

Each front coil spring broke about two years apart I was driving about 55 mph on a busy city highway when I suddenly felt what appeared to be a badly balanced tire. I managed to exit and stop in a retail parking lot and inspect the tires. What I found was a broken front driver side coil spring resting on the tire. The tire was hot enough to smoke. The tire was no longer usable. About 2 years ago on the same vehicle the passenger side front coil spring broke, but did not rub on the tire. It seems so odd that two coiled springs broke on the same vehicle. After hearing of other failures I thought it should be reported. I do feel blessed that an accident did not occur in either case.
