The vehicle horns worked intermittently during the first year, but don't work at all now. When the alarm operates, the lights will flash, but there is no sound from the horns. Based on feedback from owners' forums, there is an issue with the horn relay surface-mounted to the underhood fuse panel. This requires replacement of the fuse panel. Not having an operational horn is a safety issue for other motorists and me, as well as wildlife.

STEERING,WHEELS,SERVICE BRAKES — Filed 03/23/2026

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.

My Elantra has 25000 miles and has had issues with an inoperative horn. It appears that the horn pad switch/clockspring has an intermittent contact issue. It has progressed to the point where the horn is inoperative now. My vehicle is under factory warranty, so I will need to return the vehicle to the dealership to correct this problem. My goal is to leave a record of the failure of this critical safety device.

LANE DEPARTURE — Filed 12/30/2025

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.

LANE DEPARTURE — Filed 12/19/2025

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. I also mentioned to them that my dashboard and Infotainment system constantly dims then brightens for no reason whatsoever. Sometimes, it dims for two seconds, then goes bright again, sometimes it dims for much longer. This happens everyday and it doesnt matter if it is a bright sunny afternoon or an early morning. It constantly dims then brightens. The dealer keeps saying they can't find anything wrong because diagnostics shows everything is ok with their computer. I feel like they are simply sweeping this under the rug because it is a leased vehicle and I am concerned for my safety should I suddenly lose power.

ELECTRICAL SYSTEM — Filed 11/08/2025

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.
