While taking a corner on a highway (on/off ramps) going more than 80km/h or 45miles/hr the entire car start shaking (mainly front portion). No lights come on, and it doesn't seem to lose traction either.

Any ideas? The car was bought used and driven during summer/fall seasons only. Tires are summer..but may be a little dull.

 

check your motor mounts, when they go bad they leak.

 

..but nothing's leaking and it drives fine....

It hasn't gone through a thorough inspection since my wifey bought it in 2011, just regular maintenance.

I drive the new xv crosstrek from Subaru, and the handling and all is much better than this 2003 Kompressor - 'cept speed, of course.
