One problem related to engine belts and pulleys 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.
Issues began with faulty starter. Then progressed to a battery of electrical issues from windows moving in reverse of desired order to horn and keys dying. Each time dealer brushed off issue. When horn and keys died (also with faulty start button) dealer tried to force me to drive unsafe vehicle until they got around to fixing the problem. Most other times the issue was ignored or I was treated as though I was making up the problem. (these problems include radio staying on when car is completely off, and after manually switching it off, it then will turn back on while the car is still off (even though the car will not start and I have to use the long hold lock function to roll windows up). The car also will reopen trunk upon close, flash passenger seat belt warnings when the seat is empty, not display gear when moving, not display mileage/fuel level while simultaneously listing mileage range from selected screen, etc. Problems are worse in extreme weather. I have attempted to have the problems fixed multiple times to no avail. Recently, I have taken the car in several times to have service light diagnosed. Dealer reset light each time without bothering to check the source. Problem progressed to engine not starting, sluggish and jerky acceleration, lurching stops, and, most recently, shutting off while driving. This is absolutely a manufacturer issue, and I am planning to pursue all options available to rectify. Not only has Volkswagen produced an unsafe vehicle, but they are also aware of these problems and make a great effort to avoid dealing with them.
