I have the same problem with my 2011 Tiguan and it hasn't gotten any better in 28000 miles!I've had my 2012 Tiguan SE for about 3 months now. I love the car but since day one the transmission has been shifting into the next gear way to early causing mild vibrations and rattling. I can control this by using the Tiptronic mode. Dealer said to be patient while the computer adjusts to my driving habits. I have 1,200 miles on the car and the dealer says that should be enough time for the car to have adjusted. Apparently the early shifting improves gas milage. He says VW should be putting out a computer program update to correct this. Does anyyone else have the same issue with the transmission. If so, we should all contact VW to let them know about our displeasure and hopefully get the program update released sooner. Thoughts?
