Service Brakes Problems of Hyundai Sonata Hybrid - part 1

While traveling 40 mph, car flashes a warning, "check hybrid system", and then the car shuts off. No power steering and brakes are difficult. The warning is only 3-5 seconds before everything shuts down. This is definitely a hazard to myself and others. If in traffic at higher speeds, there would certainly be an accident with devastating results.

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.

After the car has sat idle for several hours when I depress the brake pedal to start the car I get a whoooomp sound. I took the car to the dealer and was told that after the car sits idle for awhile the air goes out of the breaking system and therefore it makes this sound at start up. My question are why, after two years of ownership, is it happening now? and, why isn't the part allowing air to escape replaced?.

My vehicle "check charging system" warning came upon the start up of the hybrid in the morning 12/31/2018, going to work. This was an issue on a heavy precipitous day in past. However there was not heavy rain, I turned the vehicle back off. It turned on without the warning which 1st appeared in front area and is audible. It started as I approached a stop sign. I live about 6 minutes away from work. The battery life is visible and it was not changed from mid point which has always been same. The tank had gas, no issue, and I drove it to work. I assumed with the car turned off for the 6hour shift I had, that it would possibly be relieved. I started the car to now drive to the store for quick grocery essentials. Within a 15 min time frame from work, store quick shopping there, and home again. The warning came back on. As I braked, or came to a stop for lights the warning would stop. As I pushed on gas pedal it would start. As I was approaching an intersection with traffic lights, I prepared to stop but as I got closer the car would not stop anymore than it had (which was significant) but not stopping, as I noticed the distance, my foot on the brake all the way I heard the vehicle (closing song) which is supposed to be heard when you turn the vehicle off. I looked at the dash in front of me which went blank all across the board and I braced for impact. My vehicle came to a stop because the collision occurred with this malfunction and my car hit the car in front of me. Physically we are ok. I am still paying for this vehicle and it is powerless by the curb at my residence until I can afford to have a tow truck pick it up. The dealership said no warranty, no assistance by them. I have a claim with Hyundai which is slow. You tube has so many vehicles from 2011 and recent models that are reporting same warning issues. I have a recording of it from that day.

I have a Hyundai Sonata Hybrid 2017. The braking system creates a howling sound when the brake is applied. It happened intermittently. I sent my car to the Hyundai dealer near me three times. The problem was not resolved. According to the dealer technicians, they were informed by Hyundai, the manufacturer that the sound was normal. I am concerned about the safety of driving the car. I hope NHTSA can help me to resolve this issue. Thank you.
