Why would another car be any better than fixing the one you have?
Effectively, they're both brand new and they'll be putting brand new parts
in the one you have in order to repair it.  Sure, it's disconcerting to
have the problem in the first place, but there's no benefit to replacing
the whole vehicle.  If cars didn't have problems, you wouldn't need a
warranty.  My advice is to relax and let them fix the car.  A competent
dealer will do a fine job.

It would be nice (although not part of the warranty coverage) for Hyundai
to provide you with a substitute vehicle until yours is repaired.  If
you're persistent, you'll probably get that.

("You"  and "your" refer to the vehicle owner).

I need your advice!  My sister bought a 2004 Santa Fe last week and
after driving it for one week, the engine seized.  They *think* they
know the cause, but they are not sure.  The dealership tells her all
they can do is replace the engine, then they want to keep it on the
lot for a few weeks to monitor it to make sure there are no more
problems.

My sister is livid.  She bought a new car and traded in an older one
that was no longer reliable.  She thought a brand new car ensured
reliability (I guess not the case!), now she will be stuck with a
lemon.

She is attempting to get the dealership to replace the vehicle (or do
a trade at her loss, since she does not want the lemon).  She called
Hyundai Canada to see what their policy is, and they said they do not
'replace' vehicles, only fix them.  I guess they do not have any kind
of policy that if you own the vehicle for a certain time frame and an
obvious manufacturer/assembly problem causes a problem, you get a
replacement car.

What kind of rights does my sister have in this case?  If they refuse
a trade/replacement vehicle, can she take them or Hyundai Canada to
court and sue to get a new car?

Thanks!
