Thank you for your question. My name is Steve and I am a fully qualified vehicle technician with over thirty years in the trade. Hopefully I can help you.

My first reaction would be that no the throttle pedal should not stick near the bottom of its travel, it should be smooth throughout and return immediately when released. However having said that the accelerator on your Hyundai is a fly by wire system and has no mechanical connection to the engine, the accelerator transmits a signal to the ECU which then controls the speed of the engine.

These throttle pedals do have a spring at the end of travel and that may be what you are feeling, but even with this the throttle should return as soon as its released.

The buzzing sound may be an indication that the electrical connections within the pedal mechanism are failing and I would advise getting this looked at as soon as possible.

I hope this answers your question but do please feel free to ask me for any further details.

If this does answer your question please click accept and rate me, this allows me to continue. Even after you have clicked accept you can continue to ask me further questions.

Many Thanks

Thanks Steve, the car has a service booked already and i'll get them to take a look at it. Is this a common problem on I20's?

Its actually a problem which has been found on quite a few different Hyundai models.
