2010 Hyundai Elantra electrical system problems

Purchased elantra july 12, 2012. I called my brother for financing information. He came to the dealership. Mazda of orange. When he started reading the contract the became very upset. He called out the salesman for the extra charges, taking advantage of me, by not telling me I didn't have to add these things. The manager, ask me to come to his office to close the deal. I needed a co-signer. A friend of mine said he would co-sign. We signed. The first malfunction was the cruise control.

I put my 2010 hyundai elantra in the garage about 11:00 pm on sunday night august 11, 2013. At about 01:00 am on august 12, 2013 I was awakened with my entire garage on fire. The fire appeared to come from the front of the elantra, as both front tires were completely burned with only steel wires wrapped around wheels. Engine is warped and burned. Entire front end melted. I lost my garage and contents along with kayaks on kayak trailer parked beside garage.
