Engine Knocking Noise problems of the 2012 Hyundai Veloster

Vehicle engine making knocking sound while idle and while in gear. Check engine light never came on. Low oil light never came on. Oil was low, shouldn't have been due to just having oil change, but no leak under car.

Engine is making a very loud knocking noise the car has already broken down on the interstate and had to have it towed home when I got to the repair facility they had to change the spark plugs the knocking noise is even louder now.

I was driving home then started hearing a knocking noise coming from the engine. That's when I felt my car to lose power and start to decelerate. Once it stopped it shut off , and all of my light on my dash board was on. The battery light, oil light, eps light. I went to open the hood and it smelt like something was burning. After about an hour of waiting the engine still wasn't turning over. I left my car on the side of the road at an apartment complex.

My car is having issues describing what is happening in the recall, the engine is louder than when I go out it sounds like you're knocking noise and I just got it in September. I need to speak with somebody about this since it's not listed on the recall.

While driving my car on the highway, I suddenly began to hear a loud knocking sound coming from under the hood. My car began to lose power and I was unable to accelerate. During my attempts to get my car to the side of the road the car then began to shack seconds later followed by an explosion that filled the car with smoke as it came to a complete stop in the middle of the highway. Thank god passer bys stopped to help get the car to the side of the road before anyone was injured.

I purchased this car 3/2012 Dec 2013 my car had to be taken in for the rear brake calipers , sunroof and the check engine light was on, took it in to kendall Hyundai, car was ok but had low power. Feb 2016 car had to go back in my trunk lock would not release. Oct 2016, engine had a loud knocking sound after oil change & service at the same dealership, I had to have an engine change, check engine light never goes off. As recent as may 26, 2017 my car failed , oil light flickering, check engine light on. I received the car back on Jun 22, 2017 after another engine change. The car's check engine light is still on called the dealership back and will take the car . The dealership has scheduled this Tuesday & that they will keep the car again for another couple of days. It is very disturbing because my car has now had 2 engine change and the check engine light is still on. I have lost the value in the car and it is & was lemon car. Hyundai should be shut down for selling faulty cars. I was driving the car on the highway at each engine failure. I have all my records on hand.
