2022 Hyundai Elantra Hybrid Driver assistance 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.

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.

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.

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

Vehicle has an unintended acceleration recall and I have experienced it a few times during the past few months. almost crashed into vehicle before me after the traffic stop.

Incident

May 30, 2024

Issue: manually setting cruise control to current speed (say 55mph) sets the cruise to 110mph . This has happened more than 10 times in 2 years of my ownership. 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.

2 times on freeway and 1 time on city streets, no vehicles within 100 yards and vehicle came to complete random stop. On freeway, tires skidded it was so abrupt and had neck pains for a few days thereafter. One time also on city street, corrective steering pulled shaply to right almost causing accident. Called hyundai and the representative had no advice or care to even intake the issue for records.not a safe vehicle especially since the engine has already failed and the ac has been replaced. It's now a frankenstein death trap being a danger to myself and others but they do not care.

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.

The Cruise Control will automatically set itself to either 20mph or 120mph when engaging it as usual. This happens with no common circumstances that I can see, but as it has happened over 10 times and I have only had the brand new car since Aug 31 2022 and the dealership does not seem concerned about it, I though I should report it to you. It HAS put both myself and others at risk, as the first time it happened, the car began to accelerate as fast as possible and the digital readout on the dashboard had the Cruise Control set for 120 mph and I almost ran into the car ahead of me. I have taken it to Schomp Hyundai in Aurora, CO and they were unable to reproduce the issue and no codes came up, with the exception of the LKA, which they did not deem a problem. This happens regularly and the only recourse is to pull over and restart the car. This first occurred around 20,000 miles and continues to happen without any rhyme or reason and makes me feel unsafe in my first brand new car. Thank you for taking the time to read this and I hope if this is happening to others, that Hyundai will be made aware of it and remedy the problem before someone get seriously hurt.

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

The 2022 Hyundai Elantra Blue is Hyundai's entry level hybrid model, and after purchasing it about a month ago, we started experiencing 'near misses' while changing lanes and using the blinkers.  While other models have a visible side mounted blinker on the right and left mirrors, they removed this important feature from the entry level model.  This means there is no visible blinker on the side of the vehicle.  While many vehicles have a blinker mounted on the front and rear of the vehicle with a reflector that wraps around to the side to give some visibility, Hyundai opted for small blinker lamps only visible directly at the front or rear of the vehicle.  We have recorded a video at night showing the car with it's blinkers on as viewed from the side, and the only way to see that the blinkers are on is from the reflection on other surfaces.  We actually tried the blinker in the daytime, and it is completely invisible when the blinker is on.  The vehicle does have a blind spot warning that shows the driver when someone is in the next lane, which has been helpful.  However, on a three lane freeway, we have experienced the issue where we are changing lanes at the same time as a car in the far lane, and the blind spot warning doesn't register the other vehicle until too late.  Thankfully, all we've experienced so far is honking from other drivers, but we are very concerned that this may lead to an accident.  I contacted Hyundai Consumer Affairs, who directed us to take the vehicle in to a dealership.  When we took the vehicle in, the Hyundai Dealer rep recognized the issue, but said there was nothing they could do to take care of it since it was a design issue.  We let Hyundai Consumer Affairs know what the dealership said, and they said "unfortunately the dealership would be the one to assist in the blinkers on the side mirrors.  If the dealership is stating that there is nothing they can do unfortunately this would  mean that your vehicle did not come equip".

The contact owns a 2022 Hyundai Elantra. The contact stated while driving approximately 25 MPH, he depressed the brake pedal to the floor and the vehicle inadvertently attempted to accelerate forward. The contact also attempted to accelerate; however, the vehicle inadvertently stopped. The contact then restarted the vehicle and the vehicle operated as intended. There were no warning lights illuminated. The contact also stated that the failure had occurred after purchasing the vehicle at the dealer. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 7,600.

I was traveling on a road headed to east bound 1-80 when my AEB engaged and it caused me to swerve to the left and the AEB slammed into the braking system. it lasted about 30 seconds and then clicked off and did not do it again until a few days later when traveling on the same road the AEB engaged again at the same spot causing my vehicle to swerve to the left. it then did it a third time while traveling in town at 45 mph the AEB slammed into the braking system for about 20 seconds and then released. It was very scary and not provoked as this could cause a very severe accident if not fixed.

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 driving down a highway at around 60 MPH with no one around me. As a car started to pass me on the left, my Elantra started sharply turning to the left and stopping. The dash started beeping with emergency braking lit up. The system activated on its own for no reason.
