Although it is only a minor annoyance to me personally, I have to agree
with you guys. I do think that it plays some part in the whole
traction/skid control system, but I would think that a cable system would
be workable somehow too.

Presumably, the lower compression results in better durability.

Realistically, this powertrain has been around in the U.S. since 2001
(only since late 2003MY in the Santa Fe) and there have been a few
improvements in that time, mostly in the transmission and throttle
controls. This makes it difficult for me to make any kind of experiential
conclusion in terms of real long-term reliability. In my opinion, there
have been very few serious problems, but I've also seen more issues than
I'd like with the variable intake and throttle motors. I'm currrently
replacing the block in an XG because of an issue with coolant in one of
the cylinders, but this is also the only vehicle with this powertrain that
I've seen with such a serious engine issue that wasn't owner-induced.

Re: 2005 Santa Fe Accelerator
 

I believe the accelerator position sensor is adjustable as well as perhaps
the throttle position sensor, but if these were far enough out of
adjustment to cause an issue, your check engine lamp should be on. I've
experienced defective sensors, but never one out of adjustment on this
electronic throttle system (XG, Santa Fe).

You could try reinitializing the throttle plate, but I suspect your dealer
has already done that. To reinitialize, turn the ignition key to the on
position (do not start engine) and immediately turn it back to off. Then
leave the key off for at least ten seconds. This often relieves some of
the suddenness of the acceleration.

I still think, however, that if the throttle is binding, that's an issue.
I don't think it'll significantly affect your fuel mileage, but it's a
serious safety concern. Of course, I haven't driven your vehicle, so I
don't know how much it sticks.

Re: 2005 Santa Fe Accelerator
 

Auto manufacturers can control emissions better with electronic throttle.
You stomp the pedal, the computer opens the throttle plate gradually as it
sees fit. Prevents a large amount of fuel dumping. Then again, it also
can prevent the car from doing what you want it to. I'm not sold on the
idea that electronic throttle is the way to go.

Given the sudden acceleration issue I've described, this might be a
case of unrealized potential...at least in this one instance.

Since I'm doing primarily highway driving you're probably right. If I
were mostly a city driver I'd disagree.
