EPC (Electronic Power Control) is kind of check engine light. It probably detected something was wrong. You may want to see a dealer/shop that can pull the actual trouble codes to see what is wrong. It is probably a sensor such as MAF.

MAF is the Mass Air Flow sensor. When it goes bad, the engine loses power and runs strangely.

I only suggest as a (common, though) possibility.

You can reset by OBD II computer tool normally available to many garage in Al quoz or rashidiya. They wont cost more than 50 dhs for resetting that light and configuring to lit up again after 10000 km.

Its known as control arm in wishbone suspension system

read this wiki aticle for more understanding

Battery has nothing to do once your car is started. Even if you remove the battery wire after starting the car it wont stop and you can drive the car forever without switching off.

Guy who sold you the battery may be made fool out of you. Im sorry. And dont listen to same guy anymore may be next he will ask you to repair the alternator for more voltage reading. Its all BS crap.

Instead im more than likely that your any of spark plug must have gone bad and need change. If not check air filter is clean or need a change. Check the ignition coil is healthy and delivering enough spark. Check the fuel filter isn't choked and fuel pump is sending fuel at enough pressure.

check above said things in same order and you will solve your problem faster.
