I have been told by the workers at the dealership that the engine needs to be replaced (car has roughly 87,000 miles). I was driving it down the road and it made a noise and lost power I literally had to floor it just to go around 30-40mph. Now it shakes, it's missing, and it has smoke coming from the exhaust on top of the oil consumption problem that I found out about after purchasing ad was told Kia knows about the problem. I haven't had it a year and can't drive it on the highway or nowhere else because of the possible engine fire hazard when I have a toddler in a car seat in the back seat that I may not be able to get out if fire was to happen. …

My 2017 KIA SPORTAGE has 74,695 miles. I am the 2ND owner. The engine failed at highway speed, due to so called knock sensor. This the first safety issue, no assisted steering or brakes. I paid to have towed. The Kia dealer had no loaner cars. And was told it would take up to ten weeks to get an engine. After the KIA dealer replaced the engine. The power steering, alternator, and water pump belt came off. This caused the second safety issue, as there is no powersteering making it very difficult to control as well as third safety issue the computer to stopped the engine. Again I paid to have it towed. The Kia dealer found a broken motor mount. Which they did repair and cover. Now the first week out of the KIA dealer service department there is a high pitched squeal. The KIA dealer just wrote me a quote for $800 plus dollars, stating this vital moving part is not covered.
