“The horn stopped working in our 2024 Elantra. This is a widespread issue (see NHTSA complaints and Reddit posts). I called ahead to verify with the San Leandro dealership that parts were in stock to perform this repair under warranty (prior to scheduling appointment). We arrived and were told that parts were actually not available (after a 3-hour diagnostic). What changed? Hyundai issued a TSB (technical service bulletin) informing dealerships of how this issue is to be repaired (designating a specific part number, while excluding otherwise qualified Hyundai parts). Without TSB, the…”

“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.

NHTSA complaint #11742737, 2026

“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 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.

“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. Alway…”

Lane Departure 5

“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.”

“I randomly get warning lights that my camera is disabled for Lane Departure Warning, Blind Spot Warning, Forward Collision warning, Lane Assist Warning. Each warning message I get comes one after the other stating CAMERA disabled. After a few minutes of driving, all the orange lights disappear and it seems to reset itself to normal. This has happened on three random occassions. I took it immediately to Hyundai of Bay Ridge but they said they were not able to duplicate the problem.

“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.”

“The vehicle experienced significant vibration at highway speeds and during braking within the first 6 months of ownership.

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.
