    I keep getting this error message Hybrid System Warning! Safely Stop and Do not Drive with the caution symbol. I have take it to the dealership 5 times and they do not see anything wrong. Usually the message flash for a few seconds and then go away. Today it did something different. The display keep alternating with Check charging system and Hybrid System Warning! Safely Stop and Do not Drive along with a beeping sound. I had to pull over and restart the car. I travel in rural areas for work, and I am so afraid my car is going to stop in the middle on nowhere. When I googled the error message it appears so many other Sonata owners from 2011-2014 are experiencing the same problem. I have reported this to Hyundai warranty, but when they contact the dealership, they tell them nothing is wrong with my car. Please advise of what to do.
