The 3.5 has electronic throttle and seems to have a small lag between
depressing the pedal and actual acceleration.

hyundaitech,
Any idea if Hyundai is aware of the problem? Any fix available?
I have the same problem with my 2005 Santa Fe (3.5). I only notice it about
50% of the time so I'm not always sure what to expect when I step on the
gas. I've has some 'thrilling' entrances to traffic due to this. I've also
had times when I overcompensated for a delay that didn't happen.
Thanks,
Jon

There are reprograms for 2003 and 2004 for smoother feeling initial
acceleration. I haven't seen anything yet for 2005, and I don't know if
there's any intent to release anything.

Is this a hesitation or jerking when you accelerate from a stop or red

Yes, exactly.

My car is in the shop right now for that very thing. I have been told what
the problem is and how it is to be resolved, but until I get it back in my
possession so I can drive it and feel if there's a difference I won't trust
the diagnosis.
Also, if the problem is resolved, I will post what was done. Apparently,
this is becoming a common issue.

So what did they say the problem is and how will they resolve it?

Zeppo, the part was ordered today. It should come in between now and
Wednesday. Like I said at the end of my message, if the problem is
resolved with the action they take, I will pass the information on to this
site.

Dan,
Got my car back--what a difference! The car had to be reprogrammed. It's
called reflashing. Problem was it wasn't taking on my car. The first time
it took, but when this happened again, there was no recognition of the
reflashing having been done. The next step was to replace the PCM--Power
Control Module. It has something to do with the onboard computer. For now,
I am able to merge into traffic, pick up from a stop or slow down without
this hesitation or lag. Hope this helps you. My car is a 2004 Santa Fe. As
Hyundaitech said, I don't know if this is available yet for 2005. Check
with your dealer.

Excellent! I'm glad it worked for you. I'm going to contact my dealer and
find out if it available for 2005 yet.

The service manager could not find that there was any update available for
2005. This surprised me as the car has been out for 6 months now. Is there a
'higher authority' I can check with?
TIA,

I’m having the same trouble with my 05 santa fe. The dealer says it
can’t be fixed. Anyone know if they have found a fix for this
problem??

I had asked about this here earlier as I was having the same problem with my
2005 3.5L Santa Fe and some users reported they were helped by reprogramming
the ETC. Unfortunately these were all 2003 and 2004 model owners who
responded.
I didn't get a chance to take it in to be looked at until this week. I
talked to the service manager about the TSB's issued for previous years
covering this problem and he said he would check it out.
When I picked up the car they said the tech couldn't find a problem, so
there was nothing to fix. When I drove it home the problem was indeed gone.
No more hesitating or surging.
I can only guess that whatever diagnostics they did reset some bit in the
programming that fixed this. Unfortunately, I can't report exactly what they
did to fix the problem.
