My brand new mini van has a very loud, annoying rumble just before every shift. If you are traveling in a cruise at that speed, it is very annoying. At the 120 kph range, it is VERY annoying. I have had it in 3 times to the dealership. They say it is not that bad. First they said it was the torque converter not being broken in yet. Now they say it is an exhaust vibration. In any case, my Pontiac Montana was always quiet. I love the stow n go seats but not this loud noise.
Very comfortable with good gas mileage, however the loud noise just before shifts is annoying.
I bought a new 2009 Grand Caravan on July 28, 2009 and have the exact same problem you do with exhaust vibration. First I brought it back to the Dodge dealer and all they said is that "everything is up to spec" and there's not a problem. Today I brought the vehicle to a Midas shop and said there was nothing he could do since it is still under warranty. The minivan also rumbles loudly at idle.
Have you come up with any answers from your dealer yet? Anybody else have any ideas? My Grand Caravan isn't even 2 months old.
Mann... Dodge STILL don't know how to make a good vehicle! FOR ONCE.
