sounds like its time for a tune-up...

it means you are doing irrepairable damage to the catalytic converter, you should take your car and have the trouble codes retrieved, sounds like you need an Oxygen sensor

Sounds like the timing is off in your car. In the Accent's if the timing is not set perfectly when it is put back in the car will not start

Sounds like a bad starter to me. When starters get hot, they sometimes fail.

hi may i suggest you have alternator output /charging checked also considering age of vehicle ? if origional battery ? have the battery checked for charge storage it may be failing to hold charge which would explain the problem you mention regarding use of h/lights slows starter rotation ?

seems to be a worn clutch... Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.

Sounds like a bad ignition switch or could possibly be needing a new battery.

it should tell you on the cap of the oil what oil and start with 4 qrt and then let sit for a few minutes then chec dipstick usauly its 5 qrts

have you checked the belt tensioner? It could be going bad.
