While driving on a highway in oregon, my car stalled and made weird sounds out of nowhere. On a broad curve, my car slowed down quickly and luckily there weren't any cars behind me. There was no warning that the engine was going to fail. I tried to pull over safely to the narrow shoulder and let the car cool down for a little bit. I tried starting it again and the engine sounded like rocks in a blender. I have taken great care of my hybrid and has no history of other issues and it only has 89,000 miles on it. The mechanic said the engine needs to be replaced and that it is a common problem with the 2. 4 l theta ii engine from my car's year.
2011 kia Optima. Engine seized while driving on the highway. Almost crashed. Swerved off the road, it made a funny noise under the car and then I had no control and the engine died. I just had the oil changed and the mechanic said the oil was black. It sucked up all the oil causing this to happen. Very dangerous. Never received a recall or letter anout this. Two weeks in the ahop and still no engine.
