Check Engine Light On problems of the 2014 Hyundai Elantra

Troubles with the power/battery. Troubles started around 80k miles. At first the battery was a suspicion. A new battery was bought and then we were told a specific battery was needed which we obtained and put into the car. I am unsure if the battery is the issue (at this point I don't think it is). Recently, the car at about 86k miles, has had times where it does not start. For example, times where we go to the store or even left overnight, the car will not turn on. No sign of life at all. We wait a while then try it again. After a while, the car eventually turns on but there is no telling how long it will take. There have been occasions where we are driving and the dash board lights will all turn on at once then turn off. Other times we will be driving and the radio/clock screen will randomly turn off and on as if the car was turned off. At this point we are worried we will be stranded if we take this car out into the community. The car has not turned on while at home, visiting out in the community, and at work. The lights on the dash and radio face acts up while driving. No check engine light has ever came on.

Just over 100,000 miles the check engine light came on. Had the repairs completed, then the engine blew completely.

The car engine shut off numerous times. The panel did not show any codes - no check engine light was lighting. Eventually the problem got worse, and the car stopped more frequently in city/street driving and on the chicago edens highway during rush hour, with no check engine light appearing. This is a very serious safety concern. Upon taking the vehicle to multiple auto mechanics for the purpose of receiving multiple opinions, the Hyundai dealership mechanics told us we needed to change the engine - with no solid reasoning or incremental evidence that the problem was a) truly, an engine mechanics or other related operating issue or 2) serious enough problem to require an entire engine overhaul. When contacting Hyundai America, they were not able to accept the facts of which are a very serious, immanent manufacturer concern, and more importantly, consumer confidence and safety concern. There were no recalls on this vehicle. We have entire reason to believe based on our factual information that Hyundai is presenting dishonest and potentially harmful information to their customers, from the vehicle's lack of safety notification and improper response in handling the situation with the consumer. I talked with the Hyundai case manager. Their system has my info and my car info, and our conversation. I had informed case manager, that I'm going to file a complaint to NHTSA against Hyundai poor performance and issue resolution. Thanks for your support and your investigation.

While driving my 2014 Hyundai Elantra it started to slow down, and the check engine light came one along with the a flashing oil light. I found it funny because I had just had the oil changed 1 week before. The next thing I knew the car just stopped mid driving in heavy traffic on the freeway. . I had it towed back to the mechanic and they checked everything out and I was told I needed a new engine. I don't see how when I keep my matience up on my car. But as I look up things on the internet I see the 2014 Elantra is giving alot of people problems when it comes to the engine. And I am not sure why Hyundai has not done a recall on the engines here in the us but have done so in canda and overseas. I am a medical retired service member and on a fixed income. So paying 1000s of dollars for a new engine is not in my budget. Nor buying a new car . . . Hyundai has been great with customer service thus far but now I am frustrated and sick to my stomach with the way I have been treated. Thank you for nothing. . .
