I am looking at a 2017 Kia Sportage EX, low miles, lease return, certified used. I am aware of the recent class action settlement related to the engine problems and it includes 2017 model year. However, most of the reviews are good, KBB & Edmunds both like it, and many of the problems I read about are for vehicles through the 2014 model year. So, is a later model year Kia a safe bet? How common are the engine problems in the newest generation?
