Around a year ago (feb 14, 2018), I received a message "hybrid system warning, please stop now". My car shut down and thank god, I was pulling into my apartment complex. My car was inspected and was told it was the tps system. That was replaced and I was on my way. Over 7 months ago (july 2018), I received the same message; "hybrid system warning, please stop vehicle now". After the warning, my car stopped immediately and this time the road was clear and I was able to coast to the side of the road. After thornton road hyundai inspected my care again, this time they stated it was the motor. After over $5000 worth of work here it is april 2019 and the same warning. This time I was stranded on a busy highway. Once the tow truck guy got there, he escorted me to his truck to be safe. I have looked into this warning over a year and no one seems to know the problem. This should be a recall and all hyundai dealers should be made aware of what this warning is. We as hyundai owners need answers and help. I cannot afford to put money into a car when the problem is only being patched up.

Major failure occurred. I was driving my car when I heard sharp bells ringing from the car dash. Check hybrid systems lights illuminated on dash. The car was in motion when it just stopped. I had no time to pull to the side of the road. I turned it off and on again. I was in the center of the road and it would not move. Good samaritan pushed my car to side of the road. The check brakes light came on. Then the car would not turn on at all. The car would not recognize the key pad light came on. Locks would not operate. The window was stuck in the open position. The internal car lights were on and would not go off. The key pad could not lock/unlock the car. Luckily this happened on a side road. 1 mile earlier I was on a freeway that had no shoulder. If it had happened there, it could have been catastrophic. Numerous systems failed. I took it to they dealer. They had to wait for the hybrid specialist. He said the transmission fluid was very dirty and ordered a new transmission. My question, why would check hybrid systems come on and so much electrical failure if it was the transmission. I have read in forums that this has happened to several other hybrid sonata owners. Even after the transmission repaired, I still feel very unsafe in the car now. If it had happened just 1 mile earlier, my car stopping immediately on the freeway with no shoulder could have caused a major accident and been life-threatening.

I have had my car for a couple years. Randomly, I got an alert while keeping regular maintenacnce on my car saying "check brakes" and "hybrid system warning". I brought it to the dealership and they said the "hecu, hydraulic electronic control unit (hecu)" is faulty. This is an issue with the hyundai genesis, but not an active recall on the 2013 sonata hybrid. However, I believe my model of car is affected by this issue, as well. The dealership said they could not do anything for me because there is not active recall, so I am reaching out to you to report this. I hope an investigation can take place for this because I know I am not the only one affected by this issue at no fault of my own. Thank you so much.

While I was driving the car stopped and wouldn't start, all the lights came on,message on dashboard read "hybrid system error" "check charging system" than everything went off, no power, no emergency lights, this in the middle of a busy street. Luckily a sheriff's was nearby and rerouted cars. Very scary. Seems I am not the only one that has a similar experience. This happened when I was going to work at 7:45am at s very busy intersection. Car is at mechanic's shop.

On october 28, 2017, I was injured in an automobile collision, which was caused solely by a malfunction by my 2013 hyundai sonata. On that date, I was driving my vehicle safely and carefully, like I always do. I was proceeding slowly in my car, and traveling between 10 miles per hour. I stepped on the brake pedal and tried to bring my vehicle to a complete stop. However, when I stepped on the brake pedal, the brakes would not engage, and the car kept moving forward and the shifting gears got stuck. Despite my multiple efforts to apply sufficient force to the brakes, the car would not stop. I then tried to disengage the transmission by placing the shift selector to 'neutral,' but I could not move shifter or move the shifter from 'drive' to 'neutral.' despite pressing firmly on the button and shifter, I was unable to put the car in neutral, and it proceeded forwarded until it struck a street sign, whereupon my vehicle came to rest. This is not the first time I had these problems with my car. I purchased my vehicle on or about october 15, 2014 from mission hills hyundai ('dealer'), and have always had it serviced there. Earlier this year, on or about may 18, 2017, I took my car to the dealer to have the brakes and transmission inspected and serviced. At that time, I explained to the dealer service department that I was having difficulty with the brakes and shifter when putting the car into reverse.

For the past 3 years a siren goes off in my car and the lites start flashing such as brake lights, the key fob light states showing as if it can't be found in vehicle. Most of all the vehicle can't start. The first time I brought it to one dealership to have my battery replaced. The second year I had the same thing happened right in the mist of traffic, the car stopped and couldn't move, same symptoms and had to have it towed from south phila. To burlington nj., results were that the relays had failed. Just this week I went to start my car and nothing happened. Tried again and the interior lights started blinking and a siren like a diving submarine started blaring. Called the tow service and again brought it to dealership. This time my car is at the shop with no clue as to what's wrong with it

We bought this car used from the dealer early on we had hybrid warning system issues we have been stuck on the side of the road several times having to have the car towed to the dealer recharged and service each time we were told they don't find anything wrong the dealer charges the battery and gives the car back. Now 3 years later we got the oil changed as normal, it's thanksgiving week and we are headed to vacation 3 hours from home we ar e an hour away from destination and the car loses power going up hill the oil pan light comes on, we pull over in the middle of the mountains and sit on the side of the road waiting for the tow truck to find us. We tow the car to the dealer hoping something wasn't done right with the oil changed however dealer says the engine seized and the car is outside of warranty and extended warranty so we will need to pay $6600 to replace with used engine. This car is 4 years old we regularly had the oil changed. We are not given any reason for the seized engine. Please look into this. This car has been nothing but problems since the day we got it and the dealer has never provided much help as were asked to take pictures which we did but still nothing.
