I keep having the same issue with this vehicle's fuel/propulsion system, power train, engine, cruise control. This vehicle is need it's fuel system cleaned now for a 3rd time in less then 2 years. I have done the high mileage maintenance on it as well. I drive the vehicle less than 5,000 miles a year. When I am driving the vehicle, it struggles to speed up, making me press on the gas repeatedly to get to the indicated speed limit. The vehicle does not slow down as it should when pressing on the brakes. I have to press repeatedly over and over and harder on the brakes in order for it to slow down. The vehicle jerks, speeds up without me pressing on the gas and sometimes it will not stop when prompted. I cannot put this vehicle on cruise control, because it speeds up and out of no where, it accelerates causing me to almost collide with another vehicle or object. Even when the vehicle is not in cruise control, the sudden jerks and acceleration puts me, my children and others in harm when it suddenly speeds up, jerks or will not stop in time. It makes a loud noise and jerks even when the car is in a resting position. It loses power, it speeds up when i need it to stay the same speed or slow down. I fear this vehicle is unsafe. I have reported these issues and a few more to the dealership who never responded, so I had to go over their heads, then finally I got a response from their Consumer Affairs' Department, as well as the BBB and they state because of the vehicle's age and/or mileage there is nothing they can do about it. Please help me. This is the only vehicle I have, and I am a single parent who cannot afford another vehicle. What is going on with this car? Why do I have to keep struggling to pay for something to get fixed and it is still not solved. Below, it ask for a date, but it is multiple dates, not just one. I have listed the first time it occurred. Thank you.

The first time my engine light came on was about a month after I had purchased it. The dealership told me to go to autozone to see what it could be. Report said it could possible be an oil clog or oil change. I got an oil change and the light was off. Light came on an every now and then but the car was driving fine. I got another oil change at the recommended mileage. My car won-??t start now, I thought it was a battery issue so I took it in to a mechanic to have it looked at and they said I need a new engine.

Engine is constantly burning through oil. I would get my oil checked 4 times more just to make sure I had oil and even then it would burn empty. I did not have a leak. This cause my engine to blow. This was unsafe as I could have been driving when this occurred. This is being confirmed by a certified Hyundai mechanic. No warning. Other Hyundai cars have a recall for this SAME engine issue but not my model and make
