On certain passenger, wagon, and convertible vehicles equipped with or without cruise control, a brake light switch May malfunction if it was installed incorrectly. When turning on the car, the air bag default button comes on. The interior lights do not come on. While idle car rumbles and shakes, while accelerating or decelerating car shakes (front end). My fueling system is terrible it seems as if gas sometimes doesn't get to my car it stales very often while driving or braking and accelerating again. Terrible electrical problems. Trunk will not open front light and brake lights work when they want to. When the heater is on it makes loud noise and tick even with the A/C on it does the same thing. While turning it stales and then take off really fast. While idle car rumbles and shakes, while accelerating or decelerating car shakes (front end). …
Engine continually would not start with numerous documented car electrical the problem is a Volkswagen faulty electrical design caused my wiring to burn up as a result when they placed the wiring fuse box on top of the battery causing both heat and chemical corrosion stress on the vehicles's electrical systems. Currently, no pun intended, the vehicle is unsafe to repair or drive what should I do? I cannot safely repair the car and sell it to an unsuspecting would-be owner nor does the local vw want to help me out thanks
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.

Turn signal switch malfunction and fire... Right turn signal activated without switch being activated. After about 5-10 minutes in this condition, smoke came out of steering column. Fire/marking could be seen in the switch area. Eventually the turn signal went out and the smoke/fire stoppped. Vw service replaced the switch and wire harnes. The plactic on the switch and harnes was melted and charred.
Front end crash into a stopped vehicle on county highway. Approximately 35 MPH to 40 MPH. None of the air bags deployed. Vehicle was totaled by insurance provider.

Drivers side windows and door locks won't work. Warning indicator saying door/s are open and warning beep will not stop until key removed from ignition. Continues to do this even while driving will all doors properly closed and seat belts fastened.

Sometime in early to mid 2013, I received a notice from Volkswagen that I needed to bring my 2005 Jetta in to have the driver's seat wiring harness repaired due to a recall. I had no prior problems with the air bags or warning lights. I took the vehicle in and they did the work. Within a few days, I got an error message in the display that there was a failure with the air bags. I took the vehicle back to Volkswagen. I was told that the technician failed to clear something in the computer memory so the failure message had come on. They indicated they cleared the message and the air bag light on the display did go off. A few months later, the air bag error message came on again. I tool the car back to Volkswagen. This time they said it was not related to the wiring harness and I would have to pay to have a new driver's seat side airbag installed, at a cost of about $700. …
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. …
