While driving the car on the freeway, it will jerk forward and then shortly after lose power. The car shows the battery as being barely charged. I pull over (luckily haven't been killed yet) on the side of the freeway. Let the car sit for a few minutes, restart it and the battery is half full and the car is driveable. I've read online that this is a common issue with 2012 Hyundai Sonata Hybrids. I've taken my car to a Hyundai dealership twice, and they can't find anything wrong, diagnostics show its fine. The second time I took it in they replaced the battery located in my trunk for $485. That did nothing, as the car is still randomly shutting off, and most times in the most dangerous areas of the road. I don't think Hyundai will do anything about this until numerous people are killed. Forgot to mention that sometimes when it shuts down the check oil light comes on. I've had the oil replaced and the oil sensor, so thats not the issue.
