2012 Golf TDI, brand new..Please help, dealer denies there is any vibration! Please respond and try to explain what u feel at 70+ mph on the highway! When I get above 60 my car begins to vibrate. At 77+ you can feel the shaking in on your feet, and in your face especially. This is my 4th Golf (my previous car was a 2001 jetta wolfsburg), and I have never noticed a vibration like this before. I also rent cars a lot and drive long distances so I can definitely notice when a car is vibrating. My wife says she can feel it too but thinks its doing it because its a diesel. I guess Im OK if this is normal b/c I like the car, but its very noticeable. When I took it to the dealer, they said they couldn't feel anything and I was pretty pissed but their position is how can they fix a problem they don't see. Car has 1400 miles on it, its always ridden like this. They checked the balancing and the engine for vibration, and the suspension and said everything looks OK. I created a video of a water bottle sitting on the seat with the water pulsating and sent it along. I didn't get a response back from the dealer. Any kind of tests someone can do on this car to prove its not right or is this normal bc of the tight suspension? To be honest, I have never driven a car with suspension this tight before. Should this thing be a little bouncy on the highway or lexus smooth like when I'm going 55 mph? Thanks!
