My wife and i have both experienced the same problem. while in motion and have had to come to a stop the brake pedal bottoms out and have had to pump the pedal to bring the car toa stop. took the car to the dealership; nothing was determined to be the problem. this has occurred several times.
While approaching stopped traffic on interstate-70 i applied brakes hard enough to engage the abs system. subsequent braking resulted in the brake pedal having excessive travel to within 1/2 inch of the floor board, making future stopping very unpredictable and resulting in multiple near miss accidents. the brake pedal corrected itself within about 3 days of normal driving. this exact same thing has occurred every time the abs has been engaged, which is at least 3 additional times since the first incident. each time the problem has cleared up in about 3 days, but the brakes are very unpredictable and dangerous during that time. *tr
Recurrent/ongoing brakes lights failure since june 2012 (brake lamp diode blows out frequently causing brake lamps to be inoperative). spongy brakes. have to pump and push harder than normal on brake pedal to stop. car serviced at tameron hyundai dealer in b'ham, al (states esc hydraulic module internal valve malfunction, needs replacement). *tr....updated 05/20/14 *bf the consumer no longer owns this vehicle. the vehicle was voluntarily released to the creditor and was sold april 2014. the consumer does not know if the vehicle was repaired. updated 05/28/2014 *js
While driving on h street ne in washington dc during the day, i applied the brakes from a speed of approximately 25 mph. as i passed over some gravelly surface, the anti-lock mechanisms activated. after the initial rapid pulsation associated with antilock braking, however, the brake pedal went soft and traveled nearly the full distance to the floor before re-engaging. the brakes remained in this condition for several minutes, but they returned to normal after about 10 minutes and several applications. the incident occurred again on a gravel road in late july 2012. this time the brakes never returned to normal. instead, to apply the brakes, i would have to push the pedal nearly all the way to the floor. the local hyundai dealership took my car in for service, and after a few weeks and different attempted solutions, fixed the problem. the problem has not recurred since july 2012. *tr
On a total of four occasions now i have had total brake failure--brake pedal to the floor when moving. the vehicle went to the dealership after the first incident. multiple parts were replaced. the problem occurred a second time thereafter. i captured it on video, as the problem was not duplicating at the dealership. the dealership determined the brake master cylinder was faulty and replaced it. almost eight months to the day later (today), the same problem occurred. it is intermittent and random. the brake pedal literally pushes to the floor, almost as if no fluid is in the lines. there are no recalls, tsbs, etc. i have posted this in online forums and sought answers. so far no luck. it is only a matter of time before a crash and possibly injury occur. i am very close to parting ways with the car. brakes are like jet engines; they really need to work all the time. thank you for your attention to this matter. *tr
The brake pedal goes to the floor when stopping the car. once stopped you have tp pump the brakes to keep the car from moving forward. the hyundai dealer indicated that this was an abs failure and he has replaced many units already.. my car is out of warranty. i went on to the hyundai owners forum for the genesis and this has happened alot to these cars. hyundai has replaced these abs units when the car was out of warranty. this is a safety issue and a failure to warn owners of a continuing problem. *tr
Tl* the contact owns a 2009 hyundai genesis. while attempting to stop for a traffic light, the vehicle accelerated independently. as a result, the vehicle crashed into the rear end of another vehicle. no injuries were reported and a police report was filed. the manufacturer was made aware of the failure. the vehicle was taken to the dealer. the technician replenished the brake fluid and was unable to diagnose the failure. the failure recurred on three different occasions, all involving a crash without injuries. the manufacturer was made aware of the failure. the failure mileage was 80,000.
