One problem related to turn signal has been reported for the 2011 Volkswagen Jetta. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2011 Volkswagen Jetta based on all problems reported for the 2011 Jetta.
Headlights, brake lights, turn signals and license plate lights all went out at the same time while driving at night with a toddler in the car. Numerous warnings flashed on the car. Tracked down the problem to a melted fuse connection on the fuse plate in the engine compartment, next to the battery. The fuse (f16) was also melted. I replaced the fuse and eveything is now working, but since the plate is still melted, I'm concerned the issue will reoccur. I called vw and apparently there is a service action (97am) to fix this exact issue for Jetta sedans and gtis but not Jetta sportwagens. Since I'm having the same issue, I believe that this service action should be extended to 2011 Jetta sportwagens as well.
