Hyundai Sonata brake lights flash instead of staying lit

NHTSA campaign 24V583000 · Reported 2024-08-07 · Hyundai Motor America

medium How serious is it? About this label

A moderate concern that mainly raises the chance of being rear-ended; the notice does not tell owners to stop driving, but get the update done soon.

What's wrong, in plain English

A software problem can make the brake lights flash rather than coming on and staying on steadily when you press the brake pedal. Drivers behind you may be confused about whether you are slowing or stopping, which makes it more likely someone runs into the back of your car. Dealers will reload the rear brake light software at no cost, and Hyundai is also sending the fix to cars wirelessly as an over-the-air update.

What you should do

1. Look up your VIN at nhtsa.gov/recalls to confirm your Sonata is covered by recall 267.
2. Accept the over-the-air software update if your car offers it, or book a visit with your Hyundai dealer.
3. Call Hyundai customer service at 1-855-371-9460 with questions — the fix is free.
