2024 Hyundai Elantra Steering Problems

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.

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

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 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.

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.

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.
