general problems of the 2014 Hyundai Sonata Hybrid

Hybrid system warning. Safely drop don’t drive. It comes and goes for all hybrids it has the issue.

I was driving 20 mph straight down a flat residental street. A loud dash alarm sounded in my 2014 Hyundai sonada hybrid. The dash displayed "hybrid system warning, safely stop and do not drive" . Below the warning a yellow caution triangle displayed. I attempted to give the vehicle gas, so I could pull to the side of the road, but the engine acted like it had no power. A blinking green "ready" light was displayed. The eco guide display was moving up and down from the top to bottom. I took my foot off the gas pedal and began braking. The brakes felt mushy and the vehicle was not stopping. Within a few seconds the vehicle shook and was the engine was revving up and down but like it was out of gear. After approximately 10-15 seconds, I lost the power steering and the it was almost impossible to turn the steering wheel. I again tried braking but the brakes just felt mushy and were not stopping the vehicle. I continued coasting down the road and eventually used the emergency brake to stop the vehicle. Once the vehicle was stopped I shut it off and attempted to started the vehicle again. The green "ready" light displayed on the dash as well as the warning lights. The vehicle would turn on but not start again. I put the vehicle in neutral and had several people push me to the curbside. The brakes were very mushy and almost non-existent. I again used the emergency brake to stop it. I notified my local Hyundai dealer and advised I would be towing the vehicle to them. I had just came off the freeway and had this happened a few minutes earlier, I would not have been able to get to the shoulder of the freeway. I believe this issue could have caused serious injury or death. It was literally terrifying to lose control of the vehicle the way this occurred. There was no prior warning of an issue and not enough time to react once the warning symbol was displayed.

While vehicle in motion, car just stop oversudan with a spoken message: " hybrid cells vehicle is in danger. Car will stop"and after this messgae, car stalls with no control on the breaks and steringwheel.

While driving car system warning came on to" safely stop and do not drive". Was able to pull over and stop car. Could not restart it. Had it towed then changed battery which was low. Tried to restart and did not turn on until 3rd time starting. Let engine run for about 10 min and warning came back on.

2 times the engine stalled in the middle of an intersection due to hybrid system failure. A simple fuse for the hybrid system went out and turned off all power. The main issue is that this is a very dangerous design flaw. Other hybrid vehicles have a safety feature that when the hybrid system is not working the gasoline engine will still be in full operation. Everytime the engine light goes on it kills the whole car. I got stuck on an expressway and was put in a dangerous situation when this did not have to happen because they don't have to make the 2 motors completely dependent on each other. Having the gasoline engine continue to run and be able to power the car in a hybrid system failure will save someone's life. I am not sure why this is not a requirement by law to have this safety feature.

Hybrid system warning has come on four times, car shuts off instantly, then the engine light comes on. The first time was on a city street, the second time was a the dealership when picking up the car after repair, the three time was in a parking lot, and the fourth time was on the interstate in heavy traffic. Car is not safe. Asked for a replacement with no resolution.

2014 Hyundai Sonata Hybrid was parked overnight in a garage. Early in the morning of November 24, 2014 it caught fire resulting in total loss of the vehicle and the home. The occupants were able to escape the home without injury.
