In owners' own words
The issue began approximately mid-may '17 while my car was in motion on the highway (55MPH speed limit, same speed limit for each time I experienced the issues in this summary).
I was driving on the highway when I started hearing a knocking sound coming from the engine. It got really loud, lost power and low voltage warning popped up.
"Takata recall" My engine started shaking and the car stopped!

Recalls for the 2013 Kia Optima: 9
The Hydraulic Electronic Control Unit (HECU) may experience an electrical short, which can result in an engine compartment fire while parked or driving. An engine compartment fire while parked or driving can increase the risk of injury.
The right and left headliner plates may not be secured properly, which can result in the plates detaching in the event of a side curtain air bag deployment. A plate that detaches during a crash may strike an occupant, increasing their risk of injury.
The low pressure fuel hose may be damaged, or missing heat-protective tape, which can result in a fuel leak. A fuel leak can increase the risk of a fire.
Brake fluid may leak inside the Hydraulic Electronic Control Unit (HECU), possibly resulting in an electrical short. An electrical short in the HECU increases the risk of a fire while parked or driving.
Brake fluid may leak inside the Hydraulic Electronic Control Unit (HECU), possibly resulting in an electrical short. If the HECU short circuits, there is an increased risk of an engine compartment fire.
The low pressure fuel hose may deteriorate and crack over time due to heat generated within the engine compartment. If the fuel hose cracks, a fuel leak can occur, increasing the risk of a fire.
The high pressure fuel pipe that connects to the fuel pump outlet may have been damaged, misaligned or improperly torqued during the engine replacement procedure, possibly causing a fuel leak. A fuel leak in the presence of an ignition source can increase the risk of a fire.
In the event of a crash, the air bag control unit (ACU) may short circuit, preventing the frontal air bags and seat belt pretensioners from deploying. If the frontal air bags and seat belt pretensioners are disabled, there is an increased risk of injury to the vehicle occupants in the event of a vehicle crash that necessitates deployment of these safety systems.
Machining errors during the engine manufacturing process may cause premature bearing wear within the engine. Bearing wear may result in the engine seizing, increasing the risk of a crash.
