Kia Optima all four window regulators failed, issue experienced by multiple owners on Kia Optima

Some 2016 Kia Optima owners report experiencing widespread issues with all four window regulators failing within a short time span. This problem appears to be consistent across various units, often due to the disintegration of the teeth in the small plastic gear that the motor mounts into. The average repair cost for window regulator failure is around $250 at approximately 65,900 miles, but some owners have faced repair costs as high as $620 at 74,350 miles. Additionally, there are reports of owners needing to replace all four window regulators over a year and a half, with some being charged hundreds of dollars for just one window repair, particularly when multiple regulators fail simultaneously. Furthermore, a class action lawsuit is being investigated regarding a potential defect in 2016-2017 Kia Optima and 2017 Kia Sportage vehicles that may cause the windows to get stuck open, underscoring the serious financial implications for affected owners.
