2009 Hyundai Genesis. Consumer writes in regards to vehicle brake system failure.

- Tucson, AZ, USA

My Genesis has less than 26,000 miles on it. Three days ago the brakes failed. The garage stated that it was master cylinder for the brakes. Today they called and stated that the hydraulic control unit also needs to be changed out. My wife was traveling at approximately 45 miles per hour when she attempted to slow the car down for an intersection. She was on lewis ave. In temperance mi. The brake pedal went to the floor board. It did eventually slow the car enough and she was able to exit into a parking lot. At this point we had the car towed to a garage.

I've had the car for over a year this is the second time this had happened.this all happened while the car was in motion.the part in question is called the hydraulic electronic control unit (hecu).Hyundai's recall no. Is 114.

The contact owns a 2009 Hyundai Genesis. The contact stated that the brake pedal traveled to the floorboard several times when it was depressed. The contact had to apply extreme force to ensure that the vehicle came to a complete stop. The vehicle was taken to the dealer where the brake fluid was flushed and changed, but the failure continued. The dealer inspected the vehicle and diagnosed that the hecu failed and needed to be replaced. The VIN was not included in NHTSA campaign number: 13V489000 (service brakes, hydraulic). The manufacturer was notified of the failure. The approximate failure mileage was 60,000. Updated 12/21/16

Without warning, the brake pedal traveled almost to the floor of the car before stopping the vehicle. The first occasion happened on August 7, 2013, but the problem corrected itself and the brakes seemed fine until October 20, 2013, when my husband and I were vacationing in the mountains of North Carolina, approximately 5 hours from our home. Again, without any warning, the brake pedal went almost to the floor before stopping the vehicle. We made it home safely, but the brake failure was a major safety concern. After seeing information online about a recall of the Genesis related to the brakes, we took the vehicle to the Hyundai dealership in goldsboro, nc, on October 23, and they replaced the brake fluid, which failed to correct the problem with the brakes. They told us the master cylinder needed to be replaced. Based on the history of the problem, we did not agree with that diagnosis and, on October 24, took the Genesis to johnson Hyundai in raleigh, nc, where they determined the problem was caused by a failure of the hydraulic module for the anti-lock brake system. The Hyundai company told us they are currently investigating this very same problem with the 2009 Genesis but the investigation is not far enough along to determine if a recall will be made. Further, that we should have the repairs done (over $2100) and if a recall is made, we would be reimbursed. Johnson Hyundai is trying to help us find a resolution to this issue. The vehicle is only four years old and about 10,000 miles out of warranty; $2100 in a repair bill is a lot of money for us to pay for a brake problem of which Hyundai is already aware....updated 11-12-13 johnson Hyundai and Hyundai corporation replaced the defective ABS module at no charge.
