Chevrolet Customer Care

Good after noon! My name is Daniel and I live in Puerto Rico. I currently own a automatic 2015 chevy spark which i recently bought. I been having problems when accelerating when I up a hill or simply hit the gas the car feels as it doesnt want to run then it suddenly accelerates. Everytime I come to a stop it also takes long to take off. This is the most concerning problem I have as I fear its dangerous. The other minor problem is when turning left I feel a scraping noise from the front end and when coming to a stop it seems to hesitate.
