Reading the numbers
Across the 7 model years of the Hyundai Genesis in this data, 2010 draws comparatively few complaints; 2015 is the outlier year.
Filings have fallen off, 7 in the last three years against 14 in the three before. That is normal as a generation leaves the road.
The median odometer reading at the time of complaint was 51,000 miles.
In owners' own words
Driving about 10 mph on tight curvy country road, brake pedal went to the floor. Pumping the pedal got the car to stop. Dealer said the brake force distribution module failed, allowing brake fluid to simply bypass being sent to the brakes. This is a very dangerous failure mode; it should fail by eliminating abs but still giving full brake force. There was no indication on dash lights that anything had failed.

Brakes failed - so master cylinder was replaced by dealer but brakes are still a bit spongy. Abs is not working quite right. Brake fluid had already been replaced 6 months earlier under recall, but brake control unit was not replaced. I am concerned that control unit should have been replaced and by other reports it seems Hyundai is very reluctant to pay for that. Car is still under warranty.

Brake pedal goes to the floor without much effort when at a full stop or in motion. Little to no actual braking occurs until reaching the full travel of the pedal. This is very dangerous and the dealership (burns Hyundai of marlton nj) acknowledged it is the hydraulic control unit, but refuses to replace under the 2013 recall of the unit. They quoted me at $3,024.50. Service brakes · reported at 48,000 miles
