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.

What stands out
Electrical accounts for 21% of all owner complaints filed against this vehicle, across 4 categories tracked.
The failure pattern owners describe
Buyer takeaway: A 2024 Elantra with under 2,000 miles can experience repeated horn failures (blown fuses, full replacements on backorder), false collision alerts that steer the car into traffic, spontaneous battery drain, and multiple other electrical gremlins—some posing real safety risks. Dealerships have struggled to diagnose or fix these issues, and Hyundai corporate has not provided lasting solutions.
Owners report the horn stops working without warning, often multiple times: blown fuses at 5,000 miles and recurring failures within 2 months of repair, with replacement horns on backorder. The collision avoidance system triggers false alarms on clear highways, causing abrupt braking and self-steering; owners also report safety feature icons randomly disabling with yellow warnings and constant dinging—happening almost daily on some vehicles.
One owner's audio amplifier lost all output, killing blind spot and cross-traffic alert sounds. Another's rear backup camera showed an error screen instead of video at 19,000 miles. A brand-new vehicle drained its battery and died while parked multiple times with no app warning; the owner had to manually reset the 12V battery. Owners also report accelerator delay (2-second lag after releasing the gas), moisture in window crevices, rear windows rolling down while parked, rear doors that barely open and won't stay open after lubrication, and a cracked heater console causing whistling (sealed twice but not replaced). Dealerships have been unable or unwilling to diagnose these issues properly, and Hyundai corporate involvement has not produced fixes.

My 2024 Hyundai Elantra limited horn stopped working, almost causing someone to hit me. The car only has 4,000 miles on it. I am extremely lucky I did not get in an accident because of this. Extremely dangerous issue and soon further research its a very common problem with some newer Hyundais. There needs to be a recall before some actually gets hurt!
