hi from uk have read your symptoms and from what you have described your starting /failure to turn engine ? 1st have you checked the leads to the starter motor are secure ? especially the single thin wire that fits to the starter solenoid on a spade connector ensure it is fully clipped on ? if ok ? may i suggest you try this ?= connect a single jump lead to the earth connector post on battery then the other end of jump lead to a suitable earth connection on the engine then try starter ifthis works your problem is a faulty/corroded or loose earth connection from the battery to the chassis/andon to engine usually connected to a bolt on point where trans connects to engine ? for info i have come across this problem a few times on accents and found that for some reason the thin wire connected to starter solenoid had come loose due to not clipped fully on also the earth lead from batteries have not had clean/securety loose bolt hope this helps and wish you luck

have tried to steer it a little while you turning the key? because some the steering lock was stuck.

is the check engine light on,if yes scan codes,it will point you to problem area

Your car may have an "immobilizer" which is part of the security system. It will start and stall if someone uses an "unauthorized" key to start it. In other words, a key that was not programmed by Hyundai or the dealer to run the engine. This happens if you had repairs done and immobilizer was interrupted and all keys were not present for programming and you're using one of those keys perhaps and sometimes it just loses its frequency. These systems often have a different frequency each time they're coded so all keys must be programmed at the same time every time. Sometimes the immobilizer coding process is simple and included in the owners manual...NOTE: this could be an indication of a bigger problem if it keeps happening.
Good luck

remove the starter motor and check for damage/wear on the teeth of the starter motor and the ring gear teeth on the flywheel.turn the engine by hand while checking the ring gear so as to check the condition all the way around.hope this helps

It would not hurt to change it.Sometimes the filter is over looked and not changed.
