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.

The contact owns a 2015 Hyundai Sonata. The contact stated while driving 60 MPH, the vehicle stalled without warning. The contact coasted the vehicle off to the shoulder of the highway and the vehicle was towed to an independent mechanic. The contact then discovered that the vehicle was included in NHTSA Campaign Number: 21V749000 (Exterior Lighting, Electrical System) which the mechanic linked to the failure. The vehicle was then towed to a dealer where she was informed that the part was on backorder. The manufacturer was notified of the failure. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The vehicle was not repaired. The failure mileage was approximately 100,000. Parts distribution disconnect.

-??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.

After taking my car in multiple times to be serviced for a "Hybrid System Warning" mid last year, they were unable to read any error codes or diagnose any issue. I took it to two separate dealerships with no luck fixing the issue. I then completely broke down due to the same "Hybrid System Warning" on the highway on 7/26/22 heading to Pigeon Forge, TN with two children in the car. I had to have my car towed to the closest Hyundai dealership in Knoxville. They were unable to diagnose and fix my car within the timeframe I was in town. Since Hyundai would not provide me with a loaner, I had to get a rental car to get home that I was not reimbursed for. We ended up paying out of pocket to replace the safety plug/fuse and the power relay assembly on 8/9/22. After having the car back for three months, the warning popped up again on 10/18/22 just as it did earlier that same year. I immediately called to schedule a service appointment with Hyundai and had to wait almost four months to get a service appointment here in Cincinnati. The appointment was on 1/26/23 and they have yet to "replicate the issue" so they are unable to diagnose the car. I am supposed to pick up the car this week even though it's a safety hazard. I have had two cases open with Hyundai Customer Affairs but since they cannot diagnose the car, there is nothing they can do. They have been absolutely no help at all.

After driving for 15 or more minutes, the power steering fails. The warning light for the power steering and stability control turn on at that moment, as well. This failure occurs while driving and the wheel jerks a bit if the car is in a turn. There was a power steering recall for other Hyundais of the same era, which is very coincidental.

This is the third time this has happened. The car just starts to beep and stops working wherever it is. Its died on the highway and another busy road during rush hour causing a dangerous backup in which the police needed to be called. The car just beeps and flashes on the dash "Hybrid System Warning! Safety Stop and Do not Drive". Also, "check charging system". The car just stops and basically dies on the road when this light comes. When this happens the steering wheel does not really work and the gas/breaks have limited function. This could cause a major accident on a major highway or even off of a highway. I am quite surprised that there has not been a recall for this serious safety concern.

Sonata 4-cyl

  • miles
Alternator tensioner bracket broke, causing the alternator to hang loosely, which caused the car to gradually lose electrical power to all accessories and safety equipment due to the serpentine belt being loose from the broken bracket. During traveling immediately before failure, the battery warning light illuminated on the dash panel, going on and off intermittently. Thereafter, I began losing control of all my electrical safety features, including power steering, blind spot detection, lane departure warning, forward collision warning system, and eventually power to my entire vehicle as the battery was drained of all charge. At the time of events, my family of 4, including a 2 year old and a 10 week old, were all occupants of the vehicle. With the power of the vehicle declining, the power steering was activating/deactivating intermittently causing the car to jerk one way or the other unexpectedly. Had we remained traveling on the highway at highway speeds, our safety would have been greatly compromised from the unexpected power failure to all electrical safety features. The vehicle and fractured tensioner bracket have not been inspected or confirmed by dealer or independent service provider as the vehicle is not drivable. The broken tensioner bracket is apparent and indisputable.

While I was driving, my check engine light came on. It wasn-??t flashing so I was going to continue driving to a parts house (because the dealerships around me were closed) and have them check the codes that were present. Immediately after I had that thought, I noticed the car was smoking and the battery light and the traction control light had come on, so I proceeded to pull over and shut the vehicle off. I got out and noticed the hood had soot on the edges. I called 911 and watched the car go up I-??m flames. This all happened in less than a mile. I noticed a fluid of some sort had sprayed out of my vehicle onto the road and the underneath the vehicle was coated in the fluid. This is still being investigated but I know of a lot of Hyundai/Kia vehicles have caught on fire while driving. I-??m not 100% sure of the cause yet, but I want to document that this did happen to my vehicle. I would love to update as soon as we figure out what has caused the car to catch fire while I was driving.

The issue is with the hybrid system, which malfunctioned and apparently ruined the rest of the car. The damaged components are adding up to over 75% of the car's value. The vehicle slowed and stopped suddenly on a busy road when the issue started. Currently, it has been inspected by two different shops and they have both given me the same diagnosis.
