Just purchased this vehicle in November 2015, February 29, 2016 the vehicle wouldn't start, had my sons jump it and drove it to work, after turning vehicle off tried to start again right away, vehicle dead. Made an appointment March 4, 2016 with Volkswagen dealership, they stated that the issue is a burnt alternator cable and melted fuse box. After reading numerous accounts online, it seems that is goes out between 70,000 - 80,000 miles, my vehicle had 79,000 miles when it happened. Volkswagen isn't doing anything about it even though it is a common complaint I've seen...wanting Volkswagen to pay for repair...very frustrated, don't think I would own another Volkswagen again!...if this is the way they treat customers. …
The battery to alternator wire on these cars overheats and catches fire. I own a car dealership and just had it happen to me. I was lucky and stopped anything horrible from happening but most people would not know enough to stop it or that it was happening. These cars are a huge fire hazard and you need to issue a recall. Check the pictures of burned cars on google. You wont find one complaint but many and plenty of burned cars. So I ask that you do your best to fix this issue. The car I own has a history of the alternator being serviced. Obviously a recall issue that maybe vw should figure out how to fix instead a band aid and out the door. Check car fax on this car. If someone let there car warm they could burn down there house. I am going to reroute this wire and replace it with a better grade of wire.

It started with the battery light coming on. I made it home. I turned off the car and when I tried to restart, dead. I first assumed the battery needed to recharge and did that. It wouldn't hold a charge. When I looked at the fuse block on top the battery, it was melted! Along with the wire going to the alternator. This seems to be a very common complaint with these vehicles.
