Radiator Hose problems of the 2003 Volkswagen Passat

I purchased a 2003 Volkswagen Passat from flow motors of greensboro, nc. The vehicle was certified by Volkswagen with a two year 24,000 warrant. The engine blew when is was 260 miles over or outside the warranty. The cause of the engine blowing was due to oil pressure and the lack of oil pressure in the engine. My wife and three year old were driving back from washington, d. C. To greensboro and broke down in lynchburg, v. A. The service manager at terry's Volkswagen in lynchburg towed the vehicle in to their shop and looked at the engine. They reported that a cam bolt snapped in the engine which caused the oil pressure to cease and in return caused the engine to blow. They told me that a cam bolt should never snap and this was a product failure. Flow motors retrieved the vehicle and denied any responsibility for the product failure and recommended I put a new engine in the vehicle at the cost of 6,500. I replaced the engine and a couple of months later had to replace a cooling flange at 300. 00 and after that a vacuum hose at 300. 00. Before replacing the vacuum hose there was a leak in my back floorboard and had the vehicle in at flow motors on two occasion but they could not locate the leak but still charged me 50. 00 to look for the leak. I've had to cut the carpet out of the back floorboard because of mold. Volkswagen broke my hood support bar and also refused to cover the expenses to pay for that. When the vehicle's engine blew my wife called me immediately to tell me the engine light was on. I told her to pull over immediately and she did. When she came to a stop the engine cut off and would not start back up. The engine had just over 91,000 and can't accept having to replace the engine when all the maintenance was kept up. Terry Volkswagen says the cam bolt snapped and stated that should never happen on a vehicle with only 91,000. I have complained to Volkswagen, the bbb, and currently am speaking with an attorney.
