Vehicle: 2022 Hyundai Elantra Hybrid Safety Complaint: While driving on the highway, my 2022 Hyundai Elantra Hybrid displayed a warning message stating “Check Hybrid System. Stop Safely.” Immediately after the warning appeared, the vehicle lost power and acceleration. The car entered a reduced-power mode, making it difficult and unsafe to maintain traffic speed. The warning instructed me to stop the vehicle immediately. This occurred while I was traveling at highway speeds, creating a dangerous situation for myself, my passengers, and other drivers. The sudden loss of power could easily result in a rear-end collision or other serious accident because the vehicle is unable to accelerate normally and traffic may not have enough time to react. My vehicle currently has approximately 69,000 miles and is within Hyundai’s hybrid system warranty period. I believe this issue represents a significant safety risk and should be investigated, as other Hyundai Elantra Hybrid owners have reported similar failures. I am requesting that this issue be reviewed due to the potential danger it poses to drivers and the public. Mileage at failure: Approximately 69,000 miles.

This 2022 Hyundai Elantra Hybrid poses an imminent fire and safety hazard due to catastrophic high-voltage system failures. On December 11, 2025 (Mileage: 54,527), the vehicle displayed a "Check Hybrid System" warning. The dealership diagnosed a swollen 12V battery and, critically, a melted power relay assembly and melted power cable. This indicates extreme thermal overload. The dealer stated they could not repair it independently and deferred to the Hyundai Engineering Team. This is the second major high-voltage failure. On March 23, 2024 (Mileage: 34,276), the vehicle suffered a total electrical blackout while driving at highway speeds at night. The vehicle lost all motive power, interior lights, and hazard flashers, leaving the car invisible in a high-speed lane. The high-voltage battery was replaced in April 2024, yet the system has failed again with melted wiring less than 20 months later. Despite a previous recall performed in August 2024 (Campaign 9B4 - BMS Software Update for 12V Battery Over Voltage), the electrical system remains unstable. The vehicle currently exhibits signs of thermal runaway. I have been informed by the dealer on Dec 16, 2025, that the wiring has melted, yet they initially refused to provide a repair order documenting these specific findings. This vehicle is a fire risk and a threat to public safety. I am requesting assistance in having this vehicle removed from the road immediately as it constitutes a public safety hazard.
- Forward collision avoidance › Automatic emergency braking
The emergency braking system activated and began slowing down the car on two occasions: sometime in the fall of 2022 and on 09/01/2025. In both instances, I was driving about 65mpg on an interstate. There were no cars in front of me to cause the system to activate.
- Service brakes
I was slowly pulling into a parking spot in a lot. As I approached the curb, I gently pressed the brake to come to a complete stop. However, instead of stopping, the vehicle suddenly and forcefully accelerated forward very fast without warning, resulting in a crash.

On [XXX] and [XXX], while driving at approximately 50 MPH, my vehicle experienced a sudden and complete loss of power, presenting an immediate safety hazard. The incident unfolded as follows: Without warning, the car emitted an alarming sound from the cabin. Simultaneously, a message appeared on the dashboard stating "Check Hybrid System" and instructing me to "Pull Over Safely." This was the first and only warning; there were no prior indications or symptoms of any problem before this sudden failure. Immediately upon this warning, the vehicle experienced a total loss of power. The component that failed appears to be the hybrid system itself, leading to a complete electrical system shutdown. The vehicle is currently available for inspection upon request. After safely pulling over and turning off the car, all electrical functions ceased. This included essential safety features such as hazard lights, rendering the vehicle completely inoperable and "electrically dead." My safety and the safety of other motorists were severely put at risk due to the sudden and complete loss of propulsion and all electrical systems (including safety lights) while the vehicle was in motion. This left the vehicle vulnerable and invisible to other traffic, particularly concerning if this occurred on a highway or at night, as it creates a high risk for rear-end collisions or other accidents. I have personal video documentation of this incident, which clearly shows the dashboard warnings and the vehicle's subsequent electrical failure. I am prepared to share this video upon request. Following this alarming event, I took my vehicle to the Wolfchase Dealership in Memphis on May 16 2025. The problem has not been reproduced or confirmed by the dealership. Despite their inspection, the dealership claimed they could not find any issue, stating that "no system of record is recording such code in the vehicle.

The 2022 Hyundai Elantra Hybrid Blue intermittently displays Check Hybrid System Stop Safety in instrument cluster screen, which stops the car from driving in either smart or normal. This happens on the roads and highways. This is very unsafe because at high speed when this happens you could easily get rear-ended because the car drops its speed and cannot accelerate any faster than 30 miles per hour and then it degrades to 20 miles per hour until I can find a safe place to park and turn off the car to do the reset to be able to drive again. This happens because the 12-volt lithium battery is not providing an acceptable amount of charge to the hybrid battery. This was also confirmed when I took the battery to get tested and it failed the test.The next part that is unsafe, is replacing the low 12-volt lithium battery, because it is connected to a high voltage 240-volt lithium-ion polymer battery; there a normal person cannot simply replace it. You have to know electronics to make sure you do not get electrocuted. In addition, it takes hours to take out the battery and then it’s hard to find to purchase. I feel Hyundai makes this process difficult as after spending hours to screw it out, you cannot locate the item anywhere. When I spoke to the Hyundai parts person, they could not locate it until I actually brought in the battery. The 12-volt lithium battery was nonrefundable and cost twice as much ($545.92) as I saw online, as low as $282 once I obtain the part number from the Hyundai order, which again is nonrefundable. I feel they make sure this cannot be found to force you to come to them to buy the battery, because all the labels or characters on the battery were not able to locatable. This was proven by me emailing the battery images to the parts person who was trying to find it, but could not until I bring in the actual battery. I was also told it is a special order and that they do not keep them onsite and have to be ordered and wait 7 to 10 days(pdf attach)

While driving on the freeway at 65MPH, my car suddenly displayed a "Check Hybrid System , Stop Safely" warning. The vehicle rapidly decelerated to 20MPH and would not respond to acceleration, despite pressing the pedal. This created a dangerous situation for my family, as we were forced to pull over abruptly on the side of the freeway. I had to reset the battery system before the car would restart. Alarmingly, this issue happened twice on same day on [XXX]. I have since contacted the dealership and informed about the problem. The dealership (Larry Miller Hyundai Peoria - 85382) took my car to address the issue on Feb 28th Feb 2025 and performed a HCU software update and informed me that there was a recall and assured me that the problem shouldn't happen again. However on [XXX], the same problem resurfaced. While stopped at a signal, the car once again displayed "Check Hybrid System , stop Safely" and became unresponsive to acceleration. I had to pull over and reset the battery system to get the car moving again. This recurring issue is not only frustrating but becoming increasingly dangerous. I now drive with constant anxiety, unsure when or where the car might suddenly stop again. This ongoing safety risk is unacceptable, especially a supposed fix was applied.

Cluster screen was black. Lasted for 30 minutes the initial time. Happened again, lasted for 3 days before turning back on. No turn signal sound when using turn signals. No speedometer or any of the main screen shows. No blind spot indicator lights or sounds either. No engine lights or any other lights visible before this occures. Safety was absolutely at risk. Couldn't even tell the speed I was going .

Driving on interstate at 70mph. Multiple, five or six, warnings pop up in rapid succession mostly dealing with the safety features such as distance to car in front, adaptive speed control, lane keeping. The last one was hybrid system - safely stop. The car then immediately lost all acceleration power leaving us coasting. This all happened within a few seconds. Terrifying. Luckily we had space to get over quickly. 30 miles sooner we would have been in downtown Jacksonville with no place to maneuver. Extremely dangerous. A few seconds warning then nothing. Turned the vehicle off as soon as we stopped and car was completely dead, no electrical power to anything, including flashers. Not sure how you can’t have flashers on a hybrid. Basically no warning to no power at highway speeds and then no flashers. Something is seriously wrong with this.

My Hyundai Elantra hybrid has had the horn and front radar go out 3 times. It will eventually start working again. Heavy rain or snow will disable the front radar and then it won’t go away for a while. When the front radar is out, I cannot use cruise control. It is disabled. I feel adaptive cruise control is much safer and cruise control in general. Apparently many people have similar issues. The horn not working often is also a huge concern. I am concerned I cannot rely on my car.

Sometimes when the cruise control is turned on the car starts the cruise setting at 110mph and then starts accelerating the vehicle to that speed. It does not allow the mph setting to be turned down using the controls on the steering wheel, the only way to take it out of the stuck 110 mph setting is by turning cruise control off or braking. This situation happens rarely but does occur with only the cruise control being turned on, without any further prompt. I have a video of the occurance but the website does not allow me to upload a video.

My hyundai elantra 2022 hybrid abruptly told me to pull over after driving on the highway for 30 minutes. The Hybrid Warning System light came up on dash and told me to pull over. After pulling over the car lost power and had to be jumped with the 12V battery reset button. Car is able to be driven again but will continue to have the same problem every 30 minutes unless the air conditioner and apple airplay or radio is off. I sent the car to Hyundai Dealership 7200 W Sahara Ave, Las Vegas, NV 89117 since [XXX] and the service technician did not contact me back for one week until I went in [XXX] to inquire. They said there is a voltage shortage somewhere but can not pinpoint yet and are working on it. I was given number to Hyundai customer service and a case manager is trying to contact the dealership to inquire the warranty before providing rental car. The dealership is not picking up so this write will go in [XXX] to try to connect case manager and get rental loaner car situated.

When driving the vehicle for more than 10 minutes, the dash will display " Check hybrid system. Stop safely" the vehicle will completely stall and will not allow you accelerate forcing you to pull over, turn the vehicle off and reset the 12v battery. Once this is done the car will turn on normally as if nothing happened. This issue happens randomly and without a warning. It was occurred on the highway many times while traveling 60+ mph and I had to stop abruptly and was forced to slow down drastically and pull over on a median and reset the car. Another incident, I was in the middle of intersection about to turn left and my vehicle stalled out in the middle of oncoming traffic causing cars to have to swerve to avoid me in the middle of the intersection. Also since it occurs very randomly, the car stalling out and it not allowing you to accelerate it poses a risk to drivers that are not paying attention and could cause a rear end accident. I have taken my car to the dealership twice for this issue and they have not been able to diagnose the issue but can see the history of the codes the car gave when it occurs. There was a recall and I took my vehicle so they can perform software update and the issue was still occurring despite the update. This has been occurring since late 2023. I purchased the car in 2021/2022.

We were on our way home from the beach on [XXX]. Coming through Birmingham on [XXX] in the far left (fast) lane traveling 78-80 mph with traffic flow, the car starts sounding a loud alarm with red flashing lights on the dashboard. The notification flashing said to “Check Hybrid system HEV BATTERY, Stop safely”. The car began to power down with no acceleration. I was unable to get across to the far-right lane to pull over, we had to just squeeze in between the concrete barrier and the cars flying by. Not to mention no flashers – nothing. The car is DEAD. We started to google hoping someone else had this issue and posted what we could do. There was a video for this exact issue stating to push a button on the left side of the dash that would reset the battery. We did that and it began to power back on. We rode in the far-right lane for the rest of the ride home, worried it would happen again. It did. On [XXX]., I was able to move over while it was powering down and get out of traffic. We received a notice from Hyundai around this time stating there were 3 recalls that needed to be fixed and one involved the HEV battery. We assumed it would fix this issue. We got another notice about 3 additional recalls (one also involved the HEV battery) and we called to get it scheduled but they were already booked out until Sept. So, we scheduled that appointment for the 2nd week in Sept. Fast forward a few weeks after making that appointment and after the recalls were done, it did it again 2 days in a row on my way home from work. One of these times it powered down and the only place to pull off was in a turning lane. The turning lane happened to be for oncoming traffic, but I thought I could hit the reset fast enough to be safe. It took a little longer than expected and I have many videos of this and cars were having to go around me to make their turn. I have one other I can go into more detail another way.

The vehicle, which is under warranty, has shut itself off three times with an error message regarding the hybrid system. After having the vehicle towed to the dealership, they found no codes, errors, or messages to address. As a result, they won’t proceed further with troubleshooting and told me to address Hyundai directly. This is a significant safety hazard.

The contact owns a 2022 Hyundai Elantra HEV. The contact stated that while driving at an undisclosed speed and attempting to slow the vehicle, upon releasing the accelerator pedal, the vehicle suddenly accelerated independently. The vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who determined that the power train control module required a software update. The vehicle was repaired, but the failure reoccurred. The contact stated that while her daughter was driving at an undisclosed speed, the vehicle inadvertently lost motive power. The driver was able to pull to the shoulder of the roadway, where the vehicle failed to restart. The Hybrid system malfunction warning light was illuminated. The vehicle was towed back to the dealer, who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 6,000.

This happens randomly and not possible to reproduced on-command. The dealers have refused to note this info and send it to Hyundai for investigation. Car accelerating to 110mph all of a sudden while you expect it to stay at your current speed can make one loose control of the vehicle, drive off the road if this happens near a sharp bend and potentially hitting other cars. This issue has definitely put the safety of me and other were put at risk. I believe this is a software issue and the dealers cant diagnose this on the spot. Hyundai does not seem to collect such non-reproducible complaints on their end which is really irresponsible.

Horn has failed twice. The first time it was taken to the dealership and “fixed” - now it has failed again. The second issue is that the car accelerates on its own, both at a high and low rate of speed. While traveling at approximately 60 mph on multiple occasions, when the engine transitions from the electric motor to the gas engine, it will suddenly rapidly accelerate without any additional pressure on the gas pedal. While braking at a low rate of speed, the car seems to fight the brakes and will accelerate instead, propelling the car forward. This has almost caused multiple accidents. At the first occasion (Mar 2023), the dealer did a “transmission relearn” which mostly fixed the issue, but it has aggressively returned only 3 months later (one week ago) and is extremely dangerous. While trying to move to the side of the road and stop the car, the car continues the stop-go jerking/propelling forward and is nearly uncontrollable. The vehicle is currently at the dealership again and has not been diagnosed. On the first occasion they claimed they could not reproduce the issue. There is an open case with Hyundai regarding this. There were no warning lights or signals on the vehicle.
