What's wrong?
The rear brake lights on the 2024 Hyundai Sonata tell drivers behind you when you are slowing or stopping. On these vehicles, that signal is controlled through software in the Hydraulic Electronic Control Unit, or HECU, an electronic brake-system module packaged with the hydraulic unit. The correct U.S. software keeps the brake lamps illuminated steadily when the brakes are applied.
Hyundai says the affected Sonatas were built with rear brake light software intended for foreign markets where flashing brake lights are allowed or required. In U.S. vehicles, that wrong software can make the brake lights flash and fail to illuminate properly. That means the lamps do not meet FMVSS 108, the federal standard for lamps and related equipment.
There is no warning sign before failure. You will not get a special dashboard message that the brake light software is wrong, so the VIN check and dealer remedy are what confirm and correct the issue.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific sedan is included.
What's the safety risk?
Flashing brake lights give other drivers unclear stopping signals. That confusion increases the risk of a crash, especially when traffic is close behind the Sonata. Drive cautiously and schedule the software update soon. Repair is free at any franchised Hyundai dealer.
What should I do?
- Check your VIN to confirm your 2024 Hyundai Sonata is included in this recall.
- Contact a franchised Hyundai dealer to schedule the free rear brake light software update that fixes flashing brake lights and improper illumination.
- Ask Hyundai about the over-the-air software update when you schedule service.
- Bring the recall notice if Hyundai mailed one, and reference recall number 24V583 when you call.
- Drive cautiously until the update is complete, and leave extra following distance.
What happens at the repair
At the dealer, a Hyundai technician updates the rear brake light software so the brake lights illuminate properly instead of flashing. Hyundai also plans to release the same software update over the air. The recall repair is free, whether completed at the dealer or through the software update. If you already paid out of pocket to fix this brake light condition, Hyundai's reimbursement plan covers eligible expenses. Keep your repair paperwork and ask Hyundai customer service or the service desk how to submit documentation.
