About this problem
Engine failure complaints describe engines that knock, seize or stop running entirely, often with a sudden loss of power on the road. The usual mechanical cause is wear in the connecting rod bearings, which can follow from manufacturing debris, low oil or oil starvation. Once a bearing fails, the engine usually needs to be replaced. Some failures on these engines are covered by recalls or extended warranties.
Across all owner complaints filed about the Kia Sportage since 2012, 770 (30.7%) describe engine knocking and failure, making it the most reported problem we track on the Sportage. The reports cluster on the 2012, 2013 and 2017 model years, and the 2012 drew the most, with 218. It tends to show up at higher mileage: half of the owners who gave a mileage were between 79,000 and 120,000 miles. 26 reports describe a crash or fire linked to it. 2 recalls are related to it, and recall repairs are free at any dealer.
