While on the highway, my car suddenly started shaking violently and losing power. I lost steering and was unable to accelerate. I pulled over to the side of the road and the vehicle would not start again. I took it in and a fuel injector was stuck open and it had flooded my engine. This was the second time with this vehicle that this happened.
This is the second incident with the same issue. Both times the car starts to shutter and when you give it gas it doesn't do anything and then it just dies. No steering no brakes nothing. You may or may not be able to restart the car to move it if it breaks down when it's in traffic, luckily we were able to get it fired up long enough to move it off the road.
I was traveling on the freeway when I began experiencing erratic acceleration, around which time the check engine light came on. I took the next exit, and continued to experience the same symptoms, as well as rough idling, and a bit of smoke. The car was towed to the nearest Hyundai dealership where the fuel injector was replaced under warranty.
