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 8 pm 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!! …

Passengers side headlight shorting out for 7th bulb replacement and new electrical problems. Strange, all within 6 months. My 21 yr old nursing student of ECU university has had the exact same issue while on her 4 hour trip home 7 times now. The wiring continues to fry itself in the main fuse box , now affecting theabs braking system. I paid $9K in cash and have electrical receipts, seat belt, convertible top, blower door, front end replacement, radiator, water pump, trunk latch, hydro licks on convertible, timing belt, 4 batteries, air bags! I could continue with a longer list. I added up to $17,000.00 I have in this piece of crap that continues to break monthly . I would be ecstatic to provide all receipts. Isn't problems of this great nature unreasonable for a car with 70,000 miles also considered a lemon? …
Vehicle engine stopped while driving. Battery dead, no power in vehicle at all. Found melted battery fuse box under hood. Root cause determined to be corrosion on alternator power supply cable that created heat enough to melt plastic (~450f) and burn the protective cover off the alternator supply wire back 2 inches. Poor contact due to corrosion caused battery to drain, which eventually could no longer sustain engine ignition. No warning lights prior to engine stopping. No battery power also means no power steering, no power brakes, no airbags during collision. Online forums indicate this is happening to a lot of people. It would appear to be as deadly as the GM ignition switch issue, but it is not being taken seriously by vw.
Alternator gets extremely hot, untouchable. Appears to be direct short with heavy load. Melts fuse box on top of battery. Fire hazard. Online search for other events reveal that is common occurrence even resulting in class action suit but still vw will not admit fault. All volkswagon beetles should be removed from the roads, it is a ticking time bomb. I was sitting in my car in my shop checking out systems and saw and smelled smoke coming from front of engine. Vehicle not safe to be on road with engine running. Please require grounding all these vehicles until vw does a permanent fix, even on the ones that have been repaired up until now.

My vehicle's radio shut off, warning lights came on and vehicle powered down while driving. Could not even steer vehicle completely to shoulder of road. Police officer driving by stopped and chastised me for not moving my car completely out of traffic's way. Created a very hazardous traffic situation. Police officer had to direct traffic around my vehicle for the hour it took to get vehicle home. The battery was checked and was fine. No charge on alternator. A quick google search LED to checking fuse box near battery. One fuse was completely melted/burnt as well as the alternator cable connection on vehicle. The google search made it seem as though this is a very common occurrence, yet no recall has been issued. …
2003 Volkswagen Beetle--electrical problem engine compartment fusebox melted due to a short. The car was maintained. It just passed inspection 2 weeks before meltdown. The battery was checked as well. No warning or dash lights indicating a problem. The car was nearly not possible to start in recent hot humid weather. I took it to a garage and they found the melted fusebox. This has to be changed asap because it could affect the car's computer and they aren't sure about the alternator yet as it was having a hard time starting the car. This repair is going to cost me $400.00 out of pocket so far. If this is a design flaw by vw which causes damage because they don't protect the engine fuse box or any related wiring from heat from the battery, there should be a recall. I noticed a similar post from houston, texas on this site. My car seems to be among several which have had this problem. …
