Hyundai i20 2009 - 1.2 Classic 5dr

What i thought was a great experience has turned into a financial nightmare, got the car home fine then started playing up,had to clean the throttle body,map sensor,had to buy diagnostics for it to read the specific codes, then I check the battery and whoever put the battery in has put the wrong one in,its not powerful enough for the car and is causing fault codes every now and then, so now I've had to pay out of my own pocket for a new battery which is more powerful and a new battery bracket to hold the new battery as the wrong bracket is in the car, have messaged and rung about the issues in the first week but got excuses of its a common issue and its been stood for a while and that can cause issues, because I live a 2 hour drive away wasnt going to take it back to derby to try and get sorted and didn't want to refuse the car as I need it for work, all I will say is if your going tk get a car make sure you get one closer to where you live
