caravan 2014
 

Hello everybody just looking for input and maybe an answer.
I bought my Caravan in November 2014 and have had a vibration in the front end since. I have had at least two alignment, 5 wheel balancement and got my wheels road forced twice and still have a vibration. All under warranty so didn't pay for it.

any input from experience would be nice.

Specifically when does the vibration occur? Sitting still? While driving? Does it increase/decrease with speed? only happen at a constant speed? Only does it while braking? Cornering? Please be a little more specific, it could be anything.

sorry my mistake, so the vibration start at around 80km/h and increases as we go faster.
It feels like the whole van vibrates.

What is your model year and type of engine?

my model is the SXT 2014 and i have the 3.6L engine in it.

A couple of oddball thoughts since you've already done the obvious:
- Is there anything on the exterior of the car other than the factory roof rack that would affect the car's aerodynamics (e.g., ski rack)?
- Has the dealership checked for loose suspension hardware, axles/CV joints, tie rods, etc?
- Does it only vibrate in the winter? Ice accretion on the wheels can cause vibration that a dealership might not be able to replicate.
- Does the vibration occur if you rev the engine while it's in park or neutral? This might indicate a bad motor mount.

If you bought the van new you also might consider looking into whether your jurisdiction's lemon laws apply here.

There is a TSB for the front brake rotors that could be related to what you're experiencing:
