In owners' own words
Car had a thrusting noise when accelerating on freeway, lost strength power, no warning lights were on. Electrical went out, then came back on when I tried to start it again.
After starting the car after it has been sitting for 8 hours or more, it seems the turbo charger was not engaged.
Oil is not sufficient. I'm losing oil fast and there is not an oil leak. I'm hearing a rattle noise.my radio changes media modes on its own.

Recalls for the 2012 Hyundai Sonata: 8
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, allowing fuel to leak from the pipe. 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, seat belt pretensioners, and side air bags from deploying. If the frontal air bags, seat belt pretensioners, and side air bags 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.
The seat belt linkages for both front seat belts may detach from the seat belt anchor pretensioners. If the seat belt linkage detaches from the seat belt anchorage, it can not properly restrain the occupant in the event of a crash, increasing the risk of injury.
In the affected vehicles, the seat belt linkages for both front seat belts may detach from the seat belt anchor pretensioners. In the event of a crash, if the seat belts detach from the anchor pretensioners, it can increase the risk of injury.
The brake pedal stopper pad can deteriorate allowing the brake light switch plunger to remain extended when the brake pedal is released. If the brake light switch plunger does not retract as it should when the brake pedal is not being pressed, the brake lights may stay illuminated preventing accurate communication to rearward following vehicles that the vehicle is slowing…
In the affected vehicles, metallic debris may not have been fully removed during manufacturing of the engine crankshaft. If the debris was not completely removed, oil flow may be restricted through the connecting rod bearings, causing connecting rod damage. Engine failure would result in a vehicle stall, increasing the risk of a crash.
In the affected vehicles, the transmission shift cable may detach from from the shift lever pin. If the transmission shift cable detaches, the transmission gear selection may not match the indicated gear and the vehicle may move in an unintended or unexpected direction, increasing the risk of a crash.
The curtain side airbags on these vehicles may inflate without deployment command due to an error during manufacturing. The curtain airbag may inflate without deployment command and increase the risk of injury to occupants of the vehicle.
