My car has approximately 14,000 miles on it and was purchased brand new. It still has 1,000 miles to go before the next servicing. Saturday I when driving approximately 40 miles an hour, the engine suddenly cut off and the car stopped in the middle of the road. I was able to start the car and drive for approximately 15 minutes before it slowed to 3mph and shut off again. I called the dealership where I purchased it and explained what happened. Initially they said they had not serviced the car in a year. I let the car sit for a day then checked all the fluids. The coolant level was fine and so was the oil. Monday, it cut off twice on my way to work. I drove to the nearest dealership and left it there. I had to rent a car as no loaners are available. It has been at the dealership for 5 days. They thought they fixed but when they test drove it, the car cut out again. Later that day, I received an email from Hyundai Blue link with an Automatic DTC Notification that a possible condition has been detected with my Engine Control System.

Driving 60mph on I-5 in May 2021. Dry roads, no wind. Vehicle suddenly surged (as if we ran over a speed bump at 60mph) despite there being no debris nor damage on the road surface. The surge felt like the ABS system triggered a single pulse, and then car completely turned off: no engine power, no radio power, no cabin lightning power, no dash lighting nor warning lights. Toggling the ignition to accessory didn't help. I had steering authority and brake authority. With no engine power, I pulled over to the side of the road. I inspected the exterior of the vehicle and there was no damage. I entered the vehicle and I was able to restart the vehicle normally. I drove it to a dealership and described the problem, they didn't know what it could be and were 30 days out on booking appointments, so I gave up.

While driving to work car started knocking. As soon as i arrived not even 5 miles from my home, died in my parking lot. Car had no indications of issues. Only information was due for oil change. Checked oil there was none. I was taking it in for service the next day for my regular service check. I was 62 miles over the standard time. Had to pay a tow and found out there is a hole in my engine block. Well with no indication of "Low oil" this brings a question of a information failure>?
