One problem related to wiring has been reported for the 2009 Volkswagen GTI. The most recently reported issues are listed below.
One of the hid headlamp stopped working causing the bulb fail warning light on the dash to be illuminated. I went to the auto parts store and bought a new bulb. Upon removal of the bulb access cover I found that all the insulation on allof the wiring in the headlight unit to have disintegrated causing the bare wires to touch and short out. I then inspected the other side of the vehicle and found the exact same condition. Upon contacting the dealer I was told that as the car was out of warranty I would have to purchase two new headlamp units at a cost of $500 per unit. I then contacted vwofa ( customer care ref #190304452) only to be told that again being out of warranty it was my responsibility to incur the repair costs. As the vehicle only has 60k and this is not only a safety issue but potentially hazardous and a manufacturing defect please investigate.
