I'm looking to buy a used car, most likely a Hyundai Santa Fe or Tucson.

Yesterday, I did a test drive an a Hyundai dealership on a 2004 Santa Fe
with a 3.5L engine.  Everything seemed fine except for what I call "touchy
steering".  I can't remember what the correct term is, but the feeling is
that while going straight down a highway it feels like the slightest change
in steering makes the vehicle feel unstable.  It's as if I have to
constantly pay close attention to the steering while going straight because
it feels like it will veer off in one direction or another.  The feeling is
that if the road were wet it could easily spin out.  There is no play in the
steering, so it's not like it's shifting direction on it's own while the
steering wheel remains stationary.  There is no vibration etc. -- just what
feels like hypersensitive steering.  I am going back to the dealership
tomorrow.

I'm guessing it has something to do with the alignment.  However, I work in
a job where I drive a number of different Ford Expeditions depending on
where I am based that day.  And one of them is new (2006) and has the same
steering issue that I can feel on the Santa Fe.  A number of other people
have noticed the same thing and that one vehicle has gone back to the Ford
dealership a couple of times but each time they say the alignment is fine
and they can't find anything wrong.

So, I'm just wondering if anyone has any thoughts or ideas about this
regarding the 2004 Hyundai Santa Fe.

Thanks.

(P.S.  I'm in Camden County, New Jersey.)
