Engine failed me while driving at the rate of speed 65 miles per hour on highway 20 returning from my myrtle beach vacation with me children and girlfriend with. We could have been killed the car just started decelerating as I was trying to pass another car. I had to think quick as there where semi tractors behind me I threw on my hazards and was able to give signal that I was in distress allowing other travelers to take heed. I then started moving into the left lane so that I could exit the highway the car at this point was just coasting and coasted into a gas station where I awaited road side towing. I have read several complaints here on the federal safety agency of similar incidents when will the consumers be protected against huge manufacturers we do all that were supposed to as far as maintaining our investment and then they try to stick the consumer with the bill in which they are will aware of had been manufactured with defects. I will never buy another hyundai product again in life and I will do everything in my power to make sure no one I know does either. For them not do whats right by your customers will in the end cost them way more. My vehicle came with an extended warranty and they are also trying to get out of replacing the faulty engine either way consumers think there doing everything right maintenance and warranty and still some how the big guys get off the hook of honoring there end of the deal. Its very disheartening to say the least. I have provide a very in depth letter to what work has been done on my vehicle and if you need to I am sure that all my maintenance records can be retrieved from carfax. Please please advise on what other measures I can take

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.
