This happens frequently and has probably happened at least 6 or 7 times since I purchased the car last month. Digital warning alert appears on dash for no reason saying “Consider Taking a Break” even though i consistently keep my car in my lane. The warning is both distracting and annoying, and there is no way on this vehicle to turn it off.

The contact owns a 2024 Hyundai Elantra. The contact stated that while driving 40 MPH, the tachometer, the odometer, and the power steering became inoperable, nearly causing the contact to drive off the road. Additionally, the turn signal lights were not functioning. All the warning lights were illuminated after the failure. The vehicle was taken to the local dealer, who was unable to duplicate the failure after a 100-mile test drive and returned the vehicle unrepaired. The failure persisted, requiring an AAA tow back to the dealer, who again failed to duplicate the failure during a 3-mile test drive. An independent mechanic informed the contact that the diagnostic trouble codes needed to be reset with a vehicle scanner. The vehicle was not repaired. The failure mileage was approximately 21,000.

The vehicle has less than 2,000 miles on it being a 2024 model (hybrid limited) and on more than 2 occasions without warning the car will be dead while parked. No accessories left plugged in to cause drainage, no warning from the MyHyundai bluelink app, and the dealers are completely clueless. The vehicle gets driven every day, and in order to "fix" the issue temporarily, i have to unlock the car manually using the physical key, and press the 12V reset button. That wont last long before the backup battery dies too.

The contact owns a 2024 Hyundai Elantra. The contact stated that while driving, check engine light illuminated, with a loss of power when accelerating. The vehicle was taken to the dealer where it was diagnosed with power train failure and received diagnostic code P040100. The vehicle was repaired; however, the issue persisted. The vehicle was returned to the dealer multiple times but still continued The manufacturer was notified of the failure. The approximate failure mileage was 43,000.

The Gas pedal, would not work as I was trying to accelerate when going from the ramp onto the freeway. The pedal had no pump in it, it just went all the way down as I was trying to press and the car started slowing down. I had to pull over on the side of the freeway and restart the car for the pedal to start working again. I came to the dealership the next day on 12/5/25, at around 5:45pm in which I was scheduled to come back at 8am on 12/6/25. My safety was at risk, because the car lost pedal power for me to pickup speed as I merged onto the freeway. I brought it in for inspection, at the dealership I purchased it from. There were not any signals or displays that came on during the incident.

The vehicle experienced significant vibration at highway speeds and during braking within the first 6 months of ownership. The issue was confirmed by a dealership, and the rotors were resurfaced as a corrective action. The problem has now returned, and the rear brakes have worn down to metal-on-metal at approximately 35,000 miles. The rear brake pads are also unevenly worn, while the front brake pads remain in good condition. Multiple service representatives have stated they cannot explain this level of uneven rear brake wear. The brake defect causes strong vibration that impacts steering control and vehicle stability, especially at highway speeds and while slowing down. This creates a safety concern due to reduced braking performance and loss of consistent vehicle control. The issue has been confirmed by dealerships, but the root cause has not been identified or properly resolved. No warning lights or alerts were provided prior to the failure. The vehicle is currently unsafe to drive due to the condition of the brakes.

While it may sound bizarre, I can definitively demonstrate that whenever I am present inside a car, the car become very unstable and bouncy and unsafe to operate. Not only does it not steer straight the car also becomes incapable of coasting smoothly and is constantly racing or aggressively slowing down. I can’t be the only anomaly and whatever is causing this could be widespread and is certainly dangerous. I have found it to occur only with the cars which I am inside. I would like to demonstrate this in person if possible to an investigator.

All of the electric warning lights turn on and the power steering goes out while I am driving.

When I am using cruise control, my car will just randomly slam on its breaks. I have taken my car into the dealer multiple times, and they have written it off everytime. They have said it’s “direct sunlight” yet I can prove it’s not happening in the sunlight. It happened again today when it was cloudy. It’s also happened before the sun came up in the morning. I have even filed a case with Hyundai directly, and they said if they can’t get it to mimic it, then they can’t do anything about it. But it’s so random, sometimes it happens 50 miles from home, other times it’s 300 miles from home. Always willing to let anyone inspect my vehicle to help solve this issue. I’ve been taking it to my dealer for a full year until I found out I needed to come put it here. It’s random, it won’t happen in the same spot twice. But every time it’s done it, there is never a vehicle in front of me. My assumption is there is a defect with the adaptive cruise control. I’ve talked with Hyundai and they claim they’ve never heard of this happening to anyone, yet when I google it, there are MULTIPLE forums with people stating this exact thing is happening to them. SAFETY issue is it slams on the brakes so hard I’ll go from 80 to 65 before I can get the cruise control off. If someone is behind me when it does this, they will slam into me.when I’m dropping 15 mph quickly, that vehicle behind me will hit me like I’m a stopped object. No warning lights before it happens. This has been happening since I bought my vehicle at 0moled to now where I have 34k miles

Partner was traveling at or under the posted speed limit, when the front passenger tire "blew." He lost control of the vehicle and was thrown into a home. Car is a total loss. The home is damaged, and he suffered injuries. There were no warning lights or alarms. This was a certified pre-owned, purchased 2 months prior. Milage was at 17737 when the incident occurred, 16242 at purchase. The same tire was reported as being replaced due to a flat by the dealership, before my purchase. The incident is under investigation by the insurance company. Contacted the dealer, they said that "tires blow" at any time, new or used. Instructed us to report it to Hyundai; the insurance company did that, and Hyundai stated there is no known issue with the vehicle. Tire make is Kumho brand, solus TA3 to the best of my knowledge. A police report was filed, and it was deemed related to a malfunction; the driver was not cited. Speed, drugs, and alcohol were not a contributing factor.

Towards the end of January, my car computer was reset because the car was telling me that I needed an oil change early and the dealership told me it could just be a computer issue. I then took my car to get an oil change and full vehicle inspection on February 24th, 2 days after that on the 26th I was leaving my school parking lot when the vehicle accelerated awkwardly when I was leaving out of a parking spot, I was then able to gain control back over the speed until the vehicle again abruptly accelerated and jerked to the left sending my car over a curb, deploying the air bag, and completely totaling out the vehicle.

The horn on my 2024 Elantra has stopped working. It was intermittent at first, but it doesn't work at all now. I will need to return the vehicle to the dealer for diagnosis. The vehicle has just over 13K miles on the odometer. The horn is an important safety feature, and based on the experiences of other owners of this model, it appears that this is a chronic issue. There are no messages displayed, and I will need to schedule with the dealer for warranty repairs.

When you accelerate & let off the gas pedal, the vehicle still accelerated for 2 seconds after you release the gas pedal. It is like there is a delay with drive by wire signal. This situation can cause rear end collisions & hard panic braking. Please recall this situation to prevent higher insurance cost & increased accidents!
