2022 Hyundai Elantra Hybrid

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

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.

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.
