2 Engine Failure problem

Failure Date: 04/07/2019

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 NHTSA 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.

3 Engine Failure problem

Failure Date: 12/06/2017

While driving on the interstate at normal speed, a sudden and catastrophic engine failure occurred without warning or previous engine trouble. Suddenly a warning sounded and displayed, "hybrid system warning, stop immediately, do not drive". Car was towed to a dealership and gas engine was "locked up". This occurred suddenly and created a severe danger to the operator (my wife) as she in the center lane of 3 during rush hour. This sudden engine failure was very similar to those described as covered in the 2011-2014 safety recall involving the 2. 4l engines in the base sonatas and that is the engine in my car (with the additional hybrid electric motor). I have reached out to Hyundai for assistance and they have refused siting the warranty limit of 100,000 miles. We have 109,123 on the car. I am requesting that the recall also be applied to the hybrid models. I am in the process of documenting the maintenance history and will supplement this complaint as needed.

4 Engine Failure problem

Failure Date: 09/20/2017

I loved my Hyundai right up until it died on me while driving on i26 toward columbia SC. $150 tow to the dealer in columbia to learn I had engine failure. Given I had the oil changed at my dealer in atlanta before leaving, this was a total shock. The service advisor (ryan) lets me know this happens but there is a recall. Hyundai will take care of me. Only my car isn't covered by the recall. No problem, he says, I'll just put in a claim. Since you have the exact symptoms as the recall cars, we've had Hyundai fix them via a claim. Since I had 101053 miles and the warranty is up at 100k, Hyundai informs me I am denied.
