Greetings,

After approx. 28,000 miles the Service Engine Soon light on my wife's 2003
Sorento went on last week.  We noticed a decrease in mileage and at least
one episode of hard starting.  We called our dealer and made an appointment
to have it looked at today (even though the light went off yesterday
morning).  Our dealer called us back this afternoon and gave us a report on
what was wrong - the computer sensed a misfire and we had two bad spark
plugs and a bad coil, all to be covered under waranty with no cost to us.
In fact they are replacing all of the plugs and wires just to be sure.
Funny thing is that since the plugs were rated for 100,000 miles, the dealer
didn't have any in stock so they will get them tomorrow.  No problem for us,
but I looked into replacing the plugs a few months ago and they were so
buried inside the motor that I didn't want to try it myself so better to
have them do it for free.

And another interesting item - while the truck is in the shop we also wanted
to have the fuel filter replaced.  It is inside the tank and takes about an
hour to change (definitely not as easy as my Chevy), but the service manager
called back and told us that it was an integrated one-piece unit and isn't
serviceable without changing the entire unit, but it didn't require any
servicing unless we were actually having a fuel flow problem.  I guess if
they want to talk themselves out of making money off of us then that's fine
by me also.

Cheers - Jonathan
