The top one on the right is BSD (Blind spot detection). I was keep getting alert and warning sound to check BSD system. Im not sure about the other one on the left.

Sounds like a bad sensor. Car needs hooked to a computer and diagnosed. The sluggishness is probably the car going into limp mode detecting a problem. If you just bought it from a dealer, take it back.

The car has 7 year warranty and done 56K.
Unlike US… in Australia there isn't any laws to protect buyers when purchasing a lemon car. I can't just walk in and tell the guy I don't want the car and get a refund.
Thats really unfortunate that on my first day of owning this car I have to deal with this issue.

People get rid of vehicles for a reason. Sometimes when you buy a used car you get lucky and get one traded by someone who just wanted a new car. Sometimes, they trade it because it has issues. If you purchased it from a smaller dealer who "has a person they like to send their cars to", at least it shows they may be committed to make it right. If their guy can't fix it, take it to a KIA dealer for a diagnosis. Then talk to the selling dealer. Once their guy knows what it is, he should be able to fix it. Might cost you a couple bucks at KIA though. "Or KIA will fix it under warranty" ?
