After a period of driving, which is random at best, the check engine light will appear and the vehicle will start to shudder and lose its ability to accelerate. This happens when the vehicle is in motion and happens both on the freeway at high speeds, as well as on city streets in low speeds. The only way to get this to stop is try and get to a safe space of the road and turn off the vehicle. It is very scary and dangerous especially in southern California freeway traffic and in mountain passes as you lose the ability to maintain speed in the middle of traffic. This could very easily cause an accident. This has happened to me on 7 different occasions over the past 2 months at random times.

I was driving the car and the car started spitting and did not want to go. Then white smoke came out of the tail pipe. I cut the car of and waited in traffic with my baby in the car, then turned the car back on. The engine light came on and the car drove like it had no energy. I was on my way to my new job for the first day.

While the vehicle is in motion and when I hit the brake. A click noise is always coming when we hit the brake till the end. Always happening observing from past 2 months. The other problem is when we hit the brake and and hold the shift knob it is making tick tick noise. Always happens when I showed to the mechanic they are saying it is normal because they have to do it for free of charge. Hyundai gives warranty but the dealers neglect to do. I am getting a mileage of average 10 miles if I even maintain a speed of 45-50 mph. If I put 14 gallons of gas I get hardly 225 miles and I have no problems with the car and I change the oil before the service interval.
