Hybrid system warning comes up often and everytime I take it to get assessed, something different is getting fixed. These repairs are all expensive out of pocket repairs. The problems continues to happen and I-??m constantly repairing something different.

Vehicle displayed hybrid warning while moving through an intersection on a highway. The car's engine turned off along with the power steering and brakes. Had the light not been in my favor, I would have been unable to stop on a high speed highway with oncoming traffic.

Hybrid car with various hybrid system failures that results in sudden loss of power while driving. this has occurred 3 times to me while on the highway (I-75 in South FL). Car suddenly loses power, could not accelerate but I was able to get off the highway safety. This has been reproduced at the dealer and they first replaced the hybrid generator then the hybrid battery and ECM and now it occurred again yesterday while I had 2 children with me and now they blame the transmission. This is a dangerous car that should be recalled and investigated for the true cause of sudden and unpredictable power loss.

The car has had multiple issues with the hybrid system. I-??ve taken it to the dealership about 4-5 times. They -??fix-?? the issue but a little while later I-??m having more hybrid warming issues. This last time I took it to a different dealership, paid for a diagnostic test, and was told my hybrid system was bad but because it was repaired too many times instead of replacing it, it-??s no longer covered under warranty. The issue from the last diagnostic test showed the master brake cylinder was faulty, I replaced it but I-??m still having the same issue. The mechanic I took it to did their own diagnostic test and it showed there is an issue with the hydraulic booster, high pressure accumulator short term charge. When I searched the issue, I-??ve found that many people are having the same issue with the same car/year as mine. I contacted the manufacturer and they are still not willing to fix it even though it is a possible defect in the car.

While driving, received Hybrid system warning that shut the car down. Power steering and braking were non-existent so safely stopping and pulling over was near impossible.

My 2015 Hyundai Sonata has recently been having both electrical and engine problems. Roughly a month ago, I had my vehicle completely stall in the middle of the highway. I lost power and a bunch of lights came on at once. Thankfully, I was in the right lane so I was able to safely get off the road even though I had many other cars speeding around me. I had no acceleration, I was just cruising off the highway at this point. Thankfully, my brakes did still work. Engine light and a bunch of errors turned on but went away once I pulled off and restarted the vehicle. I pulled off the road and once I decided to try and start it and go again, my car felt like it had hardly any power the whole way home. Fast forward to last weekend, I was driving home and my car would not accelerate. The engine light comes on and this time, my acceleration didn-??t completely shut off, I was just very limited. I had to ease into the gas because I felt like it was having a hard time shifting gears and keeping up with the RPMS. I felt uncomfortable pushing it above 50. As I got close to home, I noticed a knocking noise in the engine. I plugged one of my code readers in and it spit out 7e8, 7e9 and I believe it was p1326. Super rough start and feels like it-??s going to break down if I try to drive it. I-??ve left it parked since

Several times this has happened. I am driving and all of a sudden my car stops and I get a message that says Hybrid System Warning, Safely Stop and Do Not Drive. The car will coast to the side of the road at times and other times it won't. I have taken it to the Holler Hyundai dealer in Winter Park FL and they told me nothing was wrong with it. They had my car for less than an hour. I told them there was no way they could have fixed the issue but they said they did. Obviously they didn't fix it because it has happened several times since then. Now my car will not even move. It starts up, radio works, AC works, just will not move. It is at the Sanford Hyundai service shop waiting for them to tell me what it

2015 Hybrid Sonata, milages at 82,000 km, owned for 8 years. "Hybrid system warning, do not drive" message occurred, car lost 100% of its power, went into complete stop without any warnings on the middle of the highway. Hazard lights do not work and unable to warn incoming traffic that the car has completely stalled in the highway. The car is unsafe to drive. Went to Hyundai (here in Canada) several times, being charged every time for diagnostic and repair works, been told that the issues were fixed via software update. Problem persists. There are compelling evidences from different car forums, websites and NHTSA own database (28 reports under Unknown, 22 reports under Electrical sys. categories...) on the hybrid system failure or/and 100% power lost lead to complete stalled car. Although all these reports did not site any injury, major or death events, NHTSA should compel Hyundai to take appropriate actions to render the car safe to drive for the public because if accidents should happened, it cannot be undone and will affect lives of people. The public relies on a governing body to represent us and hold the manufacturer responsable to ensure that their mkt released products are safe: to save lives, prevent injuries, reduce vehicle-related crashes.

-??Hybrid System Alert-?? comes up on the dash and the system shuts down, all electrical is lost including HAZARD LIGHTS and the ability to put the car into Neutral. Since the car shuts down Hyundai says they cannot retrieve the code to solve it. It has been happening on and off for over a year and I-??ve been stranded on a dark road with no lights on the car and no ability to push it off the road. HYUNDAI IS NOT HELPING! They need to recall these cars as the issue is widespread. The car restarts after a day or so, but in that moment it is not driveable and very unsafe. It-??s clearly a flaw, as there-??s no code to be found. It needs to be recalled and fixed. AAA has towed me or come out several times and cannot understand the problem.

Sensors lights would indicate an issue and would disappear sometimes without any reason (mainly Check Engine and Tire Pressure Sensors). Indicators would trigger the opposite direction (indicate right and the left indicator would turn on). Burning more fuel than expected. Primary fuel pump stopped working resulting in car stopping in the middle of the road.
