2022 Hyundai Elantra Hybrid Problems

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.

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.

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.

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.

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.

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.

Hello, I bought a brand new Hyundai Elantra Hybrid 2022. In the first month my Navigation system started having trouble and would just stop working as I was driving. Which was very unpleasant experience. I would like to keep using it but it just wont work. I already went to the dealership for this issue but they were unable to resolve it. The only thing they could do was to restart the car. Please see the screenshots of errors for your review and investigation. Today, but accidentally discovered that my huydai has a recall and I was not informed about it. The issue at hand is following: "Safety Risk THE SUBJECT VEHICLES ARE EQUIPPED WITH DRIVER/PASSENGER PYROTECHNIC-TYPE SEAT BELT PRETENSIONERS THAT MAY DEPLOY ABNORMALLY DURING A CRASH. AN ABNROMAL PYROTECHNIC PRETENSIONER DEPLOYMENT COULD CAUSE METAL FRAGMENTS TO ENTER THE VEHICLE OCCUPANT COMPARTMENT, WHICH MAY RESULT IN INJURY TO VEHICLEOCCUPANTS." This is serious. I am scared to drive because my seatbelt can kill me if I get into an accident. I would like to ask you, please take care of this issue asap and also provide a remedy for failed notification on time which puts my life and health under risk. Thank you very much, Victoria

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.

When I come to a stop the nose doesn't nose drop. Took them a while at the shop to agree something was wrong, they had to vehicle for 2 months cut the rotors, a week later it's doing the same thing. So now it's easier to calipers hanging up heating up the rotors but they say I'm running out of warranty on it when it started I noticed it 2,000 miles and I'm reaching 10,000 now and they say the brakes run out at 12,000 even though they had my vehicle for 2 months just to cut the rotors.

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 .

I have had to replace my windshield from debris twice this year and have a crack filled in today. One small rock can make a crack and usually it takes a while for spidering to occur, but the Hyundai Elantra windshields are so temperature sensitive and must be super thin that over the course of one day in colder (below 50° F) and hotter (above 90° F) spidering occurs in a matter of hours. It is both a huge inconvenience to customers and a safety issue. Hyundai appear to have settled class actions on their faulty windshields in the past so I’m not surprised that this is an issue, but I want more to be done. I know it’s a small problem but to be on my 3rd windshield and only owning the car 1 year being the first owner is a huge problem to me

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. We dropped the car at a dealership on 8/12 and have h INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

the air bags failed in deploy and the automatic calling system failed to call the police upon impact. my mirror was taken off in a hit and run and the police were not contacted. the passenger side of my car was hit in an incorrect lane change by the other party and the intercom system did not call the police. i was rear ended in a 45 pmh zone and airbags failed to deploy and the intercom system did not call the police. i was t boned in a 45 mph zone and the airbags failed to deploy and the police were once again not called automatically by the car. due to the amount of damage to the car my lien holder lost interest and did not send any one to check on the damages, not did my insurance as i did not have collision coverage. the police after the tbone said my car looked totaled. my car was checked regularly for alignments and oil changes. there was no warning lamps or anything out of the usual on the dash. since this car was deemed totaled and beyond repair the lien holder dropped interest in the vehicle and was sent to auction on may 14th in naples florida.
