our hyundau sonata vibrates pretty bad now we have had it since it was new. has 155000 miles on it.

What is your question?

It has the 2.4 engine and has never vibrated until a couple of months ago. i mean when you open a door it shakes pretty bad.you think the door is going to fall off.

What makes this problem better or worse?

Nothing it starts vibrating as soon as you start it until you shut it off.

How long has your 2005 Hyundai Sonata had this problem?
