My engine light came on so I went to the dealer, they charged me over 500$ , to not have it totally fixed, installed a massive air flow sensor, which they charged me 417$ and the part sells at the napa for 85.02. I went and had the exhaust fixed at another garage and the Catalytic converter fixed and the light still never went off. So I had a new coil,,a new set of plugs wires , new spark plugs and they thought I got a faulty coil so another was installed. Light was off for a day, then went to get gas and removed the cap and on comes the light again. By now I'm up to 1630.82 in repairs. I searched the internet and it says the oxygen sensor is the number one problem so Ill get one tomorrow and in the meantime I was told it was the gas cap so I got a new one and replaced it. Light went off for almost a day and now back on again . I am at my wits end with this car and will never get another Hyundai as its known for stalling as my daughter had a new one in 2010 and it spent more time in shop the first 6-7 months than in her driveway.
