I brought car in for a oil change today and engine light was on, i have 48700km. They called to say it was a purge valve and they found a tiny oil leak which they say is common need to put new silicone, my question anyone else have this problem? As well like I said it has 48700 km, they said kia recommends break service, coolant flush and transmission flush at this time which will be about 500 dollars, anyone else gone through this or is this accurate have you guys had these services done as well? Thanks for you input.
