| Description of the problem | Until now (only 84k miles), my 2012 kia optima hybrid has been a great car. When leaving a driveway going about 15mph, a light tapping began when the gas engine started. A sound it was not making when driving under electric power (before the engine started). The sound quickly grew to a loud knocking, accompanied by a noticeable loss of power and throttle response. The check engine light never turned on, even after the engine blew up. All signs are pointing to a manufacturing defect, similar, if not the same as the one regarding metal filings being left on the block. This is the same engine model and year that triggered over . 5m cars being recalled. Now the same issues are happening with this model, which for some reason wasn't included. A modern and well-serviced car should last more than 84k miles. This will be a safety hazard until all models containing these engines are repaired. |
