I've had multiple issues with my vw Jetta 2003 and have put thousands of dollars into the vehicle. My limit was that alternator cable melting the fuse box and the battery. The vehicle is unsafe and could have caught on fire and potentially injured individuals or caused great harm. The sad part able the entire scenario is the fact that I contacted Volkswagen customer care that spoke with brea s. Which may not be an actual name because she could not provide it and she said that she had spoken to her leadership ashley and that they did not see this as a safety concerns and just because lots of other people had the same issue and mentioned it on a blog they were not able to help me. Now for me something that can cause a potential electrical fire for most people is a safety concern and the fact that this is a known issue with the Volkswagen Jetta and beetle models, it amazes me that vw customer care does not see it as there issue, brea was out of the auburn hills location in michigan. This really needs further attention.
For the past year I have taken my car to vw shops and highly rated top vw shops in la . My car was dying if I didn't drive it ever day. I had my car in the shop for over a month and after doing electrical checks, giving me an alternator, replacing countless batteries the problem is still to this day unsolved. In the past 6 months things have become worse and can lead to an accident if not fixed. My car has been decelerating while I am driving on the road, it happens at all different speeds and is random. The car will lock up so that I can not make it pick up speed when it starts decelerating and then out of no where it will work again but instead of letting me gradually increase the speed it blasts off in an uncontrollable manner. This is very dangerous and I have tried to get this fixed and diagnosed but no one not even vw has any idea what is happening because every time I take it to the shop it somehow doesn't happen. Now in the past week my car is taking it to the next level with the deceleration and acceleration but on top of that now it is just dying while I am driving it after doing the jerky thing. I literally was driving on the hwy and it jerked a couple of times and then the car just died while driving and the brakes and steering wheel locked up. I was able to get to the shoulder but it was absolutely terrifying and I could have been killed! the battery light came on and I turned off the car. When I tried to turn it back on it started up like nothing happened. I then tried to drive to safety but it would die over and over again. I just found out about this site and I decided to read some reports. Turns out there are 100s of other cases just like mine. Why then does vw act like they have no idea whats wrong with my car. Apparently the only way you can get them to do something about it is to have a tragedy! something needs to be done. Please help!!!!.

I have replaced my battery twice and my alternator once. My car completely shuts down when I part it. I have also turned on my car and then completely shuts down by itself, yet if I jump start it it will turn on. I'm not able to turn my car back on, as though something is draining my battery. This has been occurring for over one year now and I'm getting stranded at my last destination and have had to get towed to the mechanic show. It's getting very expensive and ridiculous. The mechanic has done his due diligence but problem is still occurring. I'm afraid to drive on the highway in fear my car will shit down!.

Fuse box on the top of the battery caught fire and melted the fusible link from the alternator to the battery connect. Going at 40 miles per hour and car shuts off, no brakes no power all electrical systems off dash lit up like christmas tree. Thank god for the ditch and that we weren't on interstate otherwise someone could have been killed or injured such as my pregnant wife.
On February 1, 2014 I turned on my car and headed to church at about 1 in the afternoon, everything appeared fine. After church I did the same; however, shortly after I had left the church parking lot the glow plug and battery symbols started flashing and suddenly my engine stopped. Out of nowhere my car stalled in the middle of the road, thank goodness I had managed to steer to the side and that the cars on the road managed to go around me because it could have turned out into a tragedy. I had never had any issues with my engine/battery nor did any of the dashboard warning lights light up prior to this incident. I tried turning my car back on several times but it was unresponsive. The battery and alternator sounded fine but for some reason the car just wouldn't start back up. Could it have been the fuel pump? my car runs on diesel and I have always fueled it with the appropriate fuel without any issues so what now? I had to push my car out of the middle of the road and call a tow service to tow my car home. Over the next week I drove a rental to work and called the Volkswagen dealership and left multiple messages for parts and service and for the person in charge of extended warranty. It's been a week and they have not answered. My car has been out of a warranty now for a while, however I have maintained it and given it the proper care so it does not make sense that a 2011 vehicle would simply stall in the middle of the road without a warning. I am sure that this is a manufacturer's defect and I would like for it to be resolved promptly, I am sure I am not the only one that has had this issue in the past as I have seen multiple complaints online about this and there has even been a few recalls for previous diesel models regarding issues similar to mine.

The alternator cable melted the fuse block and the car almost caught on fire.
Without notice factory radio with hands free/ bluetooth fails to come on. Which causes a potential hazard. Can also cause battery to drain, putting more strain on alternator, causing it to fail. Dealer wants a diagnostic charge, which finds that radio has failed. Needs to have radio replaced.

Alternator harness wiring and fuse box are under-engineered for electrical conditions and output given by alternator. This is the second time in one year I have to replace the fuse box and alternator harness wiring due to risk of engine bay fire. Many other vw owners in this generation and different models also have this problem with their vehicles. I believe this should be recalled and it is extremely dangerous to go unnoticed.
The day before the car quit, it would not start after being parked in the mall parking lot. A battery pack got it started, and it was driven home, with the thought that it needed a new battery. The following day, it was being driven to the local sears, for a replacement battery, when the abs and airbag lights came on. 30 seconds later lots of warning lights came on, and the car sputtered and stopped dead in the lane of travel. It would not turn over, and power accessories would not work. I was stopped on a very busy 2 lane back road, with no shoulders or side streets, uphill, on a blind hill. After 1 1/2 hours of white-knuckle directing traffic, and calls my auto club, and the local police; a local police officer, and a local tow truck showed up and gave me a lift to my repair shop. The mechanic's diagnosis of the problem was a partially melted fuse pack, that sits on top of the battery, and an overly resistive cable between the fuse pack and the alternator. The solution was: the cable end linked to the fuse pack was re-terminated, and the melted fuse pack was replaced. Between the tow and the repair, it set me back about $300. 00. . Read more...

I was driving at about 45 miles an hour and the vehicle suddenly lost power steering and all power. Without power steering it was difficult to get all the way over to the side of the road. The vehicle was towed by roadside assistance and to the nearest vw dealership who evaluated the problem.

The repair invoice indicates: "found alternator cable at fuse box melted, replaced fuse panel, alternator cable and fuse on front of fuse panel. Replaced wiring harness. Tested battery and charging system and road tested car. " I believe this is a fire hazard.

All warning indicators (abs, cel, airbag, ecp, battery and other instrument dash panel lights) would flicker repetitively until the car lost all power. After inspection of the engine compartment it was found that the alternator cable that attaches to the fuse box located on top of the battery was melting the fuse box and causing power distribution problems. The Volkswagen dealer recommended that they both be replaced as the cable could have become high resistance thereby causing excessive heat at the fuse box. I had the alternator cable replaced with an oem part and the fuse box with an aftermarket part. On 10-9-13 with 104k miles while driving to work at 6am in the morning, the exact same symptoms were experienced again. Luckily I was on a side road and was towed to a dealer which said that all oem parts should be used and that this is common as they had just replaced the alternator cable on another Jetta of the same generation. I requested the dealer check the entire electrical system including the alternator because the parts that were installed last year should not go bad in 1 year, the dealer said there was no other issue. I am not the only one experiencing a melting fuse box. At the links below are others who have experienced the same thing, even across other vw models. There seems to be a serious problem of melting of fuse boxes which can occur at any time the vehicle is in operation. . Read more...

As we were driving home, all the lights on the dash started blinking. The accelerator pedal stopped working in the middle of a busy intersection. The car engine continued running, but it just stalled in the middle of traffic and could not accelerate to get out of traffic. So we coasted the car for about 1. 5 miles to a family members house. When we arrived, we turned off the car and tried to restart it, it would not start. After opening the hood we noticed that the fuse box/harness that sits on the battery was very hot. We opened it and saw the far left black wire/cable was burnt up and melting the plastic in the harness. The black wire was extremely hot. I had this problem before, it was 3 years ago, but I did not know where to look. I spent over $500 fixing what seems to me the same problem as before. On the dealership receipt it said "found generator harness at battery fuse box melted causing high resistance in voltage circuit. . . . . Replaced fuse box and generator cable". On that occurrence it was so bad the burns had ruined my battery causing it to leak. I called vw manufacturing, but they were not very helpful and just told me to call my local dealer for assistance. They said it was not a safety issue, even if there was a fire hazard. My car is currently being looked, looking for an underlying cause for this. . . If it is the cable or something else in the engine. The connection was reset but the wire/cable continued to get excessively hot.
