1 Electrical System problem

Failure Date: 12/15/2018

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.

2 Electrical System problem

Failure Date: 08/17/2018

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.

3 Electrical System problem

Failure Date: 08/02/2018

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.

4 Electrical System problem

Failure Date: 11/28/2017

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.

5 Electrical System problem

Failure Date: 11/21/2017

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.

6 Electrical System problem

Failure Date: 10/28/2017

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.

8 Electrical System problem

Failure Date: 02/26/2017

I was driving on a interstate and suddenly I see "hybrid system warning message" + "check charging system" with continuous alarm beep sounds. I had to immediately move to the right most shoulder on the interstate (which I was able to as car was still on with engine running). Once, I moved to the shoulder, I turned off the engine and restarted the car with check engine light. It would turn on fine but wouldn't move and immediately it throws up the error. I have attached the pics for reference. Since car didn't turn off in the middle of highway, I was safely able to move it to the curb. I cannot imagine what would have happened if car had shut off. I had it towed to the nearest dealer and there are working on it. I just had a 45000 miles factory servicing with same dealership where the car got towed to and they checked on all the green boxes. Within a week, I had this issue. This is what troubling me.

Car stopped in the middle of local street road and not able to be driven to move to side of road. Car towed to delaer for repair. Want to warn about this danger to other owners.

Tech check a/t fluid, red color, smell normal. Reset codes, codes come back. TSB provided by tech line. Tech follow TSB#14-hc-003, result to replace oil pump control unit and recheck. After replacing oil pump control unit, same problem present. Tech replace oil pump, and found open yellow wire from oil pump unit to oil pump. Car runs normal and no codes present at this time. Tech try to put the old oil pump and pump module back in, problem happened again. Tech confirm the pump and module are bad. New oil pump and module reinstalled. Car under warranty and repair was successful. Delaer did a good job keeping me informed on the progress, even though it took longer than expected to repair the car.

10 Electrical System problem

Failure Date: 11/21/2015

As I started to slow down from 75mph the car started to beep and the ready light was flashing. Many indicator lights came on to include the battery indicator light, and the amber box with a wrench in it. It said "check hybrid charging system" and "safely pull over" as the car slowed down the car would no longer go forward, the lights dimmed and would no longer accelerate.

11 Electrical System problem

Failure Date: 12/01/2014

Rear taillight assemblies x 4 {left and right trunk hood assemblies and the outer turn signal/brakelight assemblies) have pooling of water and condensation/debris buildup inside the lens covers. Also noticed condensation and liquid buildup within the license plate illumination lenses. Very concerning as these are electrical components that are contained near the high-voltage lithium battery contained within the trunk space.

12 Electrical System problem

Failure Date: 02/21/2014

First repair done at the dealership on 2/21/14 for drivers door lock not working the car had 707 miles on it. I was given a rental car from enterprise for the duration of the repair. The repair took one day which they repaired the "left front door lock actuator latch assembly". I received a phone call stating my car was ready at 5pm, but as I did not want to drive in rush hour traffic I picked the car up the next day. Second repair for the same problem was on 6/18/2014 and the car now had 5,117 miles on it. I was given a genesis to drive while my car was being taken care of. I was phoned twice that day to say they were still looking into my car and they would get back to me. At 6pm that day they said they were still working on it. This service invoice now says the following "found loose terminal at door latch lock/unlock pin. Tweaked (?) door latch connector terminals and reassembled door locks. Doors working normally. " I picked my car up on 6/20/2014. On 6/28/2014 at work with the car now showing 5406 miles on the clock it has happened again. I have phoned the same dealership and informed them I will be there Monday (6/30/14) when they open at 7am to have this car repaired again. They have now had the car for two days and I have not heard anything back from them. I am now suing Hyundai.

13 Electrical System problem

Failure Date: 10/19/2013

When stopping at a red light or a stop sign or going up a slight driveway there is a loss of power when you apply the gas for a few seconds, and then the car surges. We were stopped behind a car and when we went to drive around them the car would only go approx 1 mph with the gas pedal flat on the floor, then the car surges. Then at other times there are no problems. The dealership is trying to tell me we are driving with one foot on the brake and one foot on the gas. I do not use my left foot for the brake. I tried taking the car out of blue mode but still had the problem.
