2022 Hyundai Elantra Hybrid Powertrain (other) Problems

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.

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.

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.

Twice with this 2022 Hyundai Elantra a rabbit has chewed partially through a wire to the transmission. Some Soy based coating that Hyundai uses is delicious to rabbits, then they partially chew through the wire, resulting in power and transmission issues during operation, including revving engine, failure to change gears, and unable to reverse. These wires need better protection as being chewed on causes a safety issue while driving before a check engine light comes on.

2022 Hyundai Elantra Hybrid Limited with 25000 was fine when I drove home from work. An hour or two later, got in vehicle which then shuddered and died. Manufacturer deflected blame to avoid performing repair under warranty but needed a new alternator. Car went into limp mode and just would not start once engine cylinders misfired (all cylinders misfired!). This issue after they refused to repair or tow, deemed it safe but almost wrecked due to it dying when driving off the lot assured there was no issue.

After driving the vehicle for about 5 miles I stopped to make a left turn and when I let off the brake and pressed the gas pedal the car crept forward but wouldn't speed up and the gas engine wasn't starting or even cranking. After about 20 to 30 seconds to gas engine started and the car drove fine for about 15 miles then I went to slow down and the car speed up on it own and the adaptive cruise control was off. Then it drove fine for a few more miles then I stopped at a red light and then began to make a right turn and the car did the same as before. It crept forward and the gas engine wasn't starting or even cranking. Then after 20 to 30 seconds the gas engine started and I was able to speed up some but then the engine would rev up but the car wouldn't speed up. It seemed like the transmission wasn't engaging. The car was parked for about 8 hours and then drove to the dealership without any issues. The service department at the local Hyundai dealership looked at the vehicle and test drove it without any issues
