On February 24, 2023, my 2019 Hyundai Veloster Turbo (~36K miles) would not accelerate and began losing power while driving. Problem seemed to be worse while driving uphill. At one point, car would also not go into reverse. Turning car off and then on seemed to resolve the issue with reverse. Similar issue occurred in early November 2022. Local Hyundai service center performed maintenance under warranty on the transmission November 7. Between November 7 and February 24, there were no observable issues with the vehicle while driving.

I exited the This knocking increased and repetition rather quickly and my car would not accelerate as it had been. I exited the Work zone area, near where my work is and as soon as I turned off my brake pedal would barely compress I literally had to put all of my body white on the brake pedal to get my vehicle to slow down I had smoke coming out of my engine compartment and lost all auxiliary power to the vehicle. I was able to Let the smoke out and see if the engine was actually on fire. It was not. I had no idea what was going on or why my pretty new vehicle Was doing this. I had it towed to a body shop who did a full diagnostic of the engine, and they came out with a report saying there was internal mechanical problems and that all of the engine oil had dissipated at a rapid rate.

On May 7th my car was completely dead when I tried to turn it on on the park lot of my work. Wouldn't turn on, no lights, doors wouldn't open or close. Car was jumped by the tow driver and when go to the dealership they couldn't not identify the problem nor could Hyundai. The tow driver told them the car was complete dead and still they gave me back the car saying nothing was wrong with it. But a about a month ago the car stalled and went completely off when I was driving on a highway 95 in miami, fl. At first I thought it could have been a human while sifting gears but now I know it wasn't. but after experiencing it a second time I know for sure it wasn't human error. Something is very wrong with this car and Hyundai have not been gable to find out what. At the event at the highway I was only able to bring the car back running by snapping the clutch and the gas. If it was an automatic car for sure that would have caused a big accident. After the last time the car died it took half a tank of gas to drive less than 30 miles. Hyundai, is sending the car home to me even though they haven't found anything wrong with yet. They are putting a "black box" for me to record the car engine activities as it happens. I feel scared and unsafe driving this car. It is such a serious matter that I want to share in case someone else experiences that same thing and I wan to make sure my struggle with this car is well known and hopefully will inspire some more investigation.
