My 2024 Hyundai Elantra limited keep slamming the breaks and Hyundai keep running me in circles and won’t fix it. I fear my vehicle will cause a collision. A case with Hyundai has been open for over 3 months.

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.

Horn is not working. After I hit 10k miles it suddenly no longer has worked, I am currently at 34250k miles and received a recall letter from hyundai themselves in case of any issues with the car but I don't have the paper. I went to dealer one time to give it a look but they were not working with me and treated me disrespectful so I gave up and been driving with no horn in car.

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!

This is a repeat incident. While driving, the speedometer stops working, tachometer, all of the collision warning systems start going through a self test, the check engine light comes on, and most concerning is the power steering. It becomes heavy, as if it is working at half power. The dealer kept the car for over a week recently, and they said that they were unable to duplicate the issue. It happened again while I was on a road trip , and I stopped by five star Hyundai in Albany ga. The service advisor was aware of similar issues have occurred on Hyundai's, but that they were too busy to look at it. She wouldn't even come out of the building to look at the car and wasn't interested in looking at my video. I tried to upload video to this form, but was unable to do so

Rear camera suddenly stopped working while reversing. Happened approximately at 19,000 miles. Don't know the cause but seems like a safety issue since rear view cameras are federally mandated. The usual camera view is now replaced by green error screen that says "No signal received. Please try again later"

The horn stopped working in our 2024 Elantra. This is a widespread issue (see the federal safety agency 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 dealership could have performed this repair under warranty with the in-stock parts. The dealership could still perform the repair, but Hyundai would not reimburse them under warranty. With a[XXX] wife, I was unable to wait and return later for the warranty to cover the repair. I paid $429 to the dealership for the repair to be done with in-stock parts. I left the dealership with a genuine & working Hyundai horn, but it was not covered by Hyundai’s warranty. Hyundai has refused to reimburse us. Two key takeaways: 1 - Hyundai is denying there is a widespread issue while secretly telling dealerships how to address it. The unpublished TSB demonstrates that Hyundai is aware of a widespread safety issue, and is failing to issue a recall. The majority of NHSTA complaints for this vehicle reference horn failure. This is a safety issue. I was involved in an accident where I could not warn another driver before the collision. 2 - The TSB is a mechanism by which Hyundai is refusing to perform repairs that should be covered by warranty. This is a violation of Hyundai’s stated commitment to customers that is not stated even in the fine print of the warranty.
