Engine Clicking And Tapping Noises problems of the 2012 Hyundai Sonata Hybrid

Engine blew a rod spontaneously while on the freeway. Going 75 miles an hour and heard a loud clicking sound that resulted in engine failure. No warning lights or indicators until after the engine seized. Left us stranded and in danger. Engine regularly maintained and no warning indicators or reason to have the car looked at prior to the event. Towed back to mechanic where he explained the engine rod had blown and damaged the engine and would require a completely new engine as a result. It's a hybrid and does not fall under the recall as of now but it's the exact same situation as the non hybrid versions. I only found out from the mechanic that there has been a problem with 2012 Hyundai sonata engines.

I was driving on the freeway when my car started driving rough. It made some loud clicking sounds and started to misfire and stutter. The next day I took it to the mechanic and he said the oil was empty, but I had just had the car in for service a few months earlier and there was no problem. The check engine and oil lights didn't illuminate. He did an oil change and tune up. The car continued to ride rough. I took it back to the mechanic a few days later and the oil was low again. There was no oil leak. He checked everything again and said it appeared the spark plugs were failing. Two weeks later I had the same problem again. I added oil. I took it to another mechanic (I was out of town). He cleaned the spark plugs. Four days later the car started acting really horrible, making loud clanking noise and stuttering. I added oil again and took it back to my original mechanic. He treated the oil and asked me to come back in a week so he could monitor the problem. The car drove smooth and without any problem then one week later, while driving to the mechanic the car made loud clanking noise and a cloud of white smoke came from the car. I had it towed to the mechanic. He is looking to replace my engine. In all this the indicator lights never came on (oil or check engine).

While driving it down the street started to hesitate frequently while driving then heard a loud clanking sound which continued on while driving it to dealer. Dealer looked at it and we were told the motor had gone out and needed to be replaced! they also said we had to pay for it because they said our oil changes were not approved! once we got the paper work back they quoted they found oil build up and large chunks of metal throughout the engine that has contaminated the valve train. They had to replace engine, cylinder head, valve, valve spring, camshafts ,gaskets! now they are issuing a recall on Hyundai sonatas for this exact problem , but they are also saying our car is not included in the recall even though what they fixed is the exact problem that is listed on the recall. It took them almost 2 months to have our car in the shop because they couldn't find the parts needed to fix the engine!!!!.
