Mid/rear Seats Assembly problems of the 2003 Volkswagen Beetle

Electrical main fuse box under hood burnt and melted into battery. See pics of burnt fuse box, and indention of melted battery. Car cut off while in motion on highway, causing my 19 year old college daughter to almost wreck in route to school last week at 8pm est. Her major is nursing. I want to make sure she's alive to see her graduate. Outside air temp was 65 degrees. This is extremely dangerous, not to mention the cost that will be associated with paying for volkswagons poor design electrical misengineering flaw, a new alternator, all electrical wiring, a new battery, and possibly new convertible top motor. Her vw is/was in mint condition with fewer than 80k miles. Vw estimates costs to fix over $5k to 6k. Kbb value is much less. My daughters life is priceless. Also, the wiring harness for the seatbelts underneath the seat are too short!! if you slide the seats back, it breaks electrical connections which triggers seatbelts light to come on, which disengages airbags to work in the event of an accident. The 2 front seats also must slide forward in order for back seat passengers to enter vehicle. Is this how vw saves money, by shortening electrical wire to connect seatbelts? perhaps it's on purpose to avoid millions of electrical lawsuits?.
