Alternator/generator/regulator problems of the 2007 Cadillac CTS

The seller lied about everything! the first question I asked was if the car was in an accident. He bragged about being a mechanic, and doing all the work on the car, so everything in the car is in, "tip top shape. " he replied, "no, never!" he did not allow us to ride the car on the interstate before the purchase, claiming it was illegal. 10 mins after leaving the car lot, the car cuts off and is unable to crank back up. The seller meets us and claims it the battery. A "new" battery was placed in the vehicle, but the problem persists. My fianc�, who is not a mechanic, told him more than once, that the problem was not the battery, but the alternator. He got the car to crank. As we are riding down the interstate, the car cuts off, and we are left aimlessly rolling and are unable to control the wheel. Plus, the electricity in the car is off so we can't even turn on our hazard lights to caution the other cars on the road. After speaking to the seller, once again, he tells us there is nothing he can do about it and will not cancel the deal. We've only had the car for 4-5 hours. After speaking to several mechanics, they quickly confirm that the alternator is the problem and anybody that claims to be a mechanic can see the problem immediately. They also inform us the car has been wrecked and should have not been resold for safety measures. Driving this vehicle almost cost us our lives.

While vehicle is running the radio turns off and on intermittently stationary or moving. The vehicles while driving shut down while driving. The car sometimes won't start when turning on the ignition switch. Airbag lights is on and check voltage light are registering while stationary or driving. The plugs, alternator and core pack was replaced hoping to resolve the issue. Took vehicle to the Cadillac dealership but they denied me any service under the recall problems I was experiencing. There position is the recall is VIN. Specific.
