Engine Shut Off Without Warning problems of the 2002 Land Rover Discovery

Of all the personal vehicles I've ever owned, I've never had one that causes me to drive like I was on "pins & needles". I was driving at highway speed when out of the blue the engine head gaskets let go, without warning. The engine shut down and I lost power steering and power brakes. After investigating with dealer inquiries and independent shops this is a common problem with Land Rover v8 aluminum engines. The dealership(s) I spoke with actually agreed with my concerns but said "talking to Land Rover is like talking to a dog, they hear you but won't do a thing about it". I could understand if this vehicle was high mileage or was really abused. Someone needs to address these people before someone gets killed.
