Brakes went completely out while driving, absolutely terrifying. Pedal went straight to the floor and wouldn't stop. I had to manually downshift until it was under 5 mph and then it would barely stop.

Service brakes, hydraulic: fluid
- What is wrong
- Hyundai is recalling certain model year 2009-2012 Genesis vehicles manufactured April 30, 2008, through March 28, 2012. The vehicles may contain brake fluid which does not protect against corrosion of the Hydraulic Electronic Control Unit (HECU).
- Risk
- If the module corrodes, reduced brake effectiveness may result, increasing the risk of a crash.
- Remedy
- Hyundai will notify owners and instruct them to bring their vehicle to a dealer for service. Hyundai will inspect the HECU module for proper operation, and will replace the modules as necessary. Hyundai will replace the factory brake fluid in those vehicles that have not previously had the factory brake fluid replaced. These repairs will be done free of charge. The recall began on December 24, 2013. Owners may contact Hyundai at 1‑800‑633‑5151 or by email at [email protected]. Hyundai's recall number is 114.

Brake hydraulic control module failure
On October 28, 2013, Hyundai Motor Company (Hyundai) submitted a Defect Information Report (DIR) to the federal safety agency describing a safety defect in the braking system of approximately 43,500 model year (MY) 2009 through 2012 Hyundai Genesis sedans (the federal safety agency Recall No. 13V‑489).The Hyundai report indicates that the recalled vehicles may contain brake fluid that does not sufficiently inhibit corrosion on the zinc plating of control valve armatures in the Hydraulic Electronic Control Unit (HECU) module. The DIR indicated that, over time, the build-up of corrosion products may affect operation of HECU control valves, resulting in a low/soft brake pedal with reduced brake effectiveness, which may increase the risk of a crash.In October 2011, the HECU supplier notified Hyundai that the brake fluid used in production plants was causing corrosion of valve armatures in the control module.The supplier changed the coating of the valve armatures in late March 2012 to correct the problem in production vehicles.Hyundai's recall includes Genesis vehicles produced prior to the implementation of the HECU change.In March 2013, Hyundai initiated a Service Campaign (TL6) to replace brake fluid in the subject vehicles with brake fluid with better corrosion resistance properties.According to Hyundai's DIR letter, after PE13-033 was opened, the company noted that some of the vehicles serviced in the TL6 campaign subsequently required HECU replacement.This was an indication that internal corrosion had progressed enough to affect valve operation and brake performance, prompting Hyundai to conduct a safety recall.Hyundai's repair procedures for 13V‑489 require brake system flushing and replacement in all recalled vehicles with a new fluid containing the necessary corrosion inhibitor.In addition, for vehicles produced prior to June 1, 2010, dealers will perform an inspection procedure to verify that the HECU is functioning properly and replace units that do not meet the test requirements.Hyundai indicated that, based on analysis of claim data, only vehicles produced prior to June 1, 2010 have been in service long enough to require the additional inspection/replacement of the HECU. Analysis of failure data reported to the federal safety agency and provided by Hyundai in response to ODI's information request letter for PE13-033 identified 756 complaints and 1,683 warranty claims for 30,114 subject vehicles produced prior to June 1, 2010, resulting in a complaint rate of 25.1 incidents per thousand vehicles (IPTV) and a claim rate of 5.6 percent.The MY 2009 vehicles, with the longest exposure times, experienced the highest complaint (33.5 IPTV) and warranty (7.0 percent) rates.For the 45,639 subject vehicles produced after June 1, 2010, ODI identified 13 complaints and 34 warranty claims, resulting in a complaint rate of 0.3 IPTV and a warranty claim rate of 0.1 percent, indicating that the brake fluid corrosion concern had not progressed far enough to result in significant rates of brake system performance symptoms in those vehicles.This investigation is closed.ODI will continue to monitor complaints to evaluate the effectiveness of Hyundai's recall.The VOQs noted in the Failure Report are: 10569231, 10560898, 10560495, 10559360, 10558279, 10558264, 10556964, 10556631, 10556577, 10556322, 10554988, 10554802, 10554122, 10552958, 10551817, 10551157, 10551110, 10551092, 10550791, 10550773, 10550431, 10549750, 10549634, 10549629, 10549567, 10549402, 10549376, 10549270, 10549228, 10549186, 10549021, 10548903, 10548823, 10548791, 10548737, 10548722, 10548716, 10548705, 10546565, 10544803, 10543663, 10542962, 10541959, 10541741, 10538208, 10537934, 10536652, 105354

What 2010 Hyundai Genesis owners say
Most recent owner complaints, unedited.
While attempting to brake on exit ramp off an interstate highway, the brake pedal was depressed almost to the floorboard with minimal slowing. The brakes were pumped several times with slowing vehicle speed. Fortunately, the exit ramp was long enough to allow a safe stop. Pedal remains soft and spongy. No warning lights are on. Brakes functioned normally until this incident at 138,200 miles. However, master cylinder was replaced at 102,000 miles for a similar problem at an independent auto shop. I am awaiting a dealer repair time. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Tl* the contact owns a 2010 hyundai genesis. The contact stated that the brake lights failed to illuminate. A dealer had not diagnosed the vehicle. The manufacturer indicated that the vehicle was serviced per an unknown recall campaign in 2014 and 2016; however, the failure persisted.

Tl* the contact owns a 2010 hyundai genesis. The contact had to depress the brake pedal excessively in order to stop the vehicle. The failure occurred without warning. The vehicle was taken to suburban hyundai (1814 maplelawn dr, troy, mi) where it was diagnosed that the master cylinder was defective and needed to be replaced. The manufacturer was notified of the failure and did not assist since the master cylinder was not part of a recall. The failure mileage was approximately 50,000.
Background: am original owner of this 2010 hyundai genesis that was purchased july 31, 2010 and that currently has less than 35,000 miles on it. Issue: unexpectedly, the brakes became "squishy" (I.e. Brake pedal depressed a long distance before engaging brakes). Advised by hyundai dealer that it is a faulty hecu unit and needs to be replaced for $3,800. Note: the brake fluid was replaced in april 2013 and the hecu unit was supposedly inspected in january 2014. I believe these were done in response to prior recalls. That said, upon some further reading on the internet, I am under the impression that when this problem was previously identified for recall, the recall should have resulted in my hecu unit being replaced, not just inspected. I intend to raise this issue with the hyundai dealer and, hopefully, hyundai will stand behind the replacement of the hecu unit without charging me.
Partial loss of braking - while traveling down the highway at 45 MPH the vehicles in front of me abruptly slowed down requiring me to quickly apply my brakes. Upon application of my brakes, I started to slow down and then the brake pedal suddenly released, providing limited braking. I continued to push the brake pedal towards the floor and the vehicle came to a stop but it required a longer stopping distance than normal.*bf updated 9/28/18
Breaks failed. Taking exit from highway and the car wouldn't stop as the breaks would work. Was very fortunate to have found gap between two lanes and avoided a major accident. Dealer confirmed the breaks failed and there have been numerous break failures reported with genessis. Had recently got breaks checked and was told 'every thing is fine'. Question is why didn't hyundai do a recall and proactively replace my break system? One whole day of suspense about how much it will cost me... And I was told hyundai would cover the cost of replacement as it was a known problem. Dealer called it 'goodwill warranty'.
