At 120,000 miles a loud knocking noise began coming from the engine at engine start. It persists and sounds almost like an electric sewing machine - taka taka taka taka. The sound gets louder when I accelerate and decreases when I don't press the gas pedal. The noise decreases slightly when the engine is fully warmed up but it is still audible. I took it to a mechanic who specializes in engines, his diagnosis was "rod bearings need replacement" I have started searching for this issue online and became aware of safety recall sc147. Unfortunately this recall doesn't include the kia Forte model. I saw in my research online that many other Forte owners were having similar issues. In addition, my car's engine "theta ii" 2. 0 liter appears to be the same engine that is included among the recalled models included in sc147. I am wondering why the kia Forte is not included as it seems to be suffering from the same issue. Is this a question of accountability, or lack thereof on kia/Hyundai's side.
