You sure its a 2004? Not sure for the SF but the electronic throttle didn't
start on the Sonata until 2006. Every engine for the 2004 SF that I looked
at on hmaservice shows a cable. sounds like a loose
My girlfriend has 2004 Hyundai Santa Fe
Most of the time the accelerator behaves normally, but periodically it
over-accelerates when you barely touch the pedal causing the car to
lurch forward, pulling your foot off he gas! This is an automatic by
the way. She’s been informed by the dealership it’s got an electronic
throttle, and there are no cable problems, and just she just needs to
be careful with the pedal. We find that answer unacceptable.
It has been a ongoing problem for about the last year or two, the
first two years she owned the Santa Fe it didn’t display this
problem. It can occur several times in one day irrespective of the
engine being hot or cold, and then not again for weeks or months.
Any advice, suggestions, or thoughts, other than “Just be sensitive
with the pedal and live with it” would be appreciated!
Thanks in Advance,
