Noticed after driving my Hyundai genesis and once running for roughly 15-20 mins once the engine has warmed up I noticed a bounce feeling coming from the front end(I thought)and then noticed my speed dropped and when pressure was apply to the gas pedal it wouldn’t go, as the car slowed down by itself until it came to a complete stop I cutt the car off and began walking around to where I smelled something burning and then seen smoke coming from my front driver wheel to discover my brake had locked up for no reason. I left the car to cool down and returned to get it and luckily it was unlocked and was successful to drive it home(4min drive), a couple days later I had to take my son to school to where it did the exact same thing again, days later I had all braking replaced which failed to solve the issue. This has been happening for over 4 months now and has always been my daily driver and has always been upkept and never had any issues with my car until now. I’m a single parent with two children whom I have to take to school daily and pickup and this issue has already cost me a lot however I was made aware of this issue by a professional mechanic whom said my car has a current recall for this exact issue I’m having but my vin doesn’t show it even thought everything lines up!

- 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 2011 Hyundai Genesis owners say
Most recent owner complaints, unedited.
The HECU has been malfunctioning in my car for over a year now. It is an open recall for my make, model and year of car. I took it to Bob Rohrman Indy Hyundai and they diagnosed the failed part. This part affects my ABS. There are currently two warning lights on one for the ECS which is the traction control stabilizer and the ABS light is on. Meaning the use of the breaking system is limited and not working properly. I have asked the corporate Hyundai to uphold the recall warranty but I was advised they would not cover this because my vehicle has a rebuilt title. I drive my vehicle on a daily basis and I’m terrified of my brakes going out. The corrosion from the fluid is what causes the HECU to malfunction and it is so scary to think about. This problem was diagnosed and first reported to my his dealership on 6/23/2022.
Brakes stop working randomly. Press pedal down and there is very little braking power. Had to pump brakes and limp home. Came back after sitting a while. This has happened several times - 6/7.
Ibrake failure! Hydraulic module assy failure was driving the vehicle and during the drive, my brake all of a sudden became soft and required me to push all the way to the floor to stop the car. I believe it's referred to as spongy brakes. I took the car to an independent mechanic shop and they diagnosed a faulty hydraulic module assembly. I also called the dealer and they mentioned there was a recall on the brake fluid due to its potential to cause corrosion in the brake system. The dealer is now quoting me ~$3,400 to repair and replace the hydraulic module assy. Wow!! I called hyundai USA and they said since the car was out of warranty they would not cover the repair, I informed them of the recall on fluid and they said it does not cover the parts that were damaged by the bad fluid. This is unfair and excessive behavior on the part hyundai. Clearly they recognized the fluid was damaging brake components but are unwilling to cover related repairs. The brakes on this car are an accident waiting to happening since the brakes are failing. I would not buy another hyundai vehicle knowing they won't cover critical safety components. Others have voiced the same issue with no support from hyundai.
The z01 diode failed causing the brake lights not to illuminate when the brake pedal is pressed. There is no warning to the driver that this failure has occurred. This is a known issue by hyundai. They released a tsb, technical service bulletin 09-be-023, concerning the issue but the solution is to replace the same diode when it has failed. No improvements have been made to make the part more reliable. It is a serious safety issue as the driver has no indication that the brake lights do not work putting them, passengers, and other drivers at risk of a serious rear end collision.
My car at 58000 miles whenever I brake on slippery surface where ABS is activated my brake pedal goes nearly down to floor. And continuous for days going down nearly to floor on normal braking before brake pedal comes back up to normal level again. This has happened now every time ABS is activated. Dealer wants nearly $3000. To replace the ABS.
My brake pedal is going all the way down to the floor it used to do it every once in a while but now it is a constant thing. The car does stop but it feels really mushy, I took the car to the dealership and was told that it was a master brake cylinder, however after reading online a lot off people have the same issue and replacing the master cylinder isn't the problem
Recall on car back in 2014 for brake failure. Improper fluid used causing ABS assist module to fail resulting in soft break pedal. Purchased vehicle in 2014 used and never told of this issue after purchasing vehicle nor never sent any info. Electrical problems , drive seat wont respond , wind shield wipers randomly turning on . Tail lights not working also on recall. This notification also never sent to use resulting in the vehicle being rear ended last year . Passenger seat head rest deployed and not drivers. Car was fixed and a couple of weeks ago the passenger head reset deployed again hitting my daughter and at the same exploded and came of its frame landing in the back seat. Hyundia dealer wont do anything other than whats on recall now.
Abs module failed. Brake pedal goes down to floor to stop the vehicle.
My 2011 hyundai genesis is experiencing braking failure. I have almost had accidents due to my car's inability to come to a stop in a reasonable time, especially when following vehicles that come to a sudden stop. The pedal depresses almost to the floor and is very spongy. The problem is intermittent but consistent. I researched the issue and found that there was a recall related to this issue, but for some reason, hyundai excluded my VIN despite it falling within the manufacture period of hyundai cars experiencing the issue. I took the car to the hyundai dealership and they diagnosed a failed ABS system, specifically stating that the internal seals of the hecu (ESC unit) were worn causing poor sealing. This may be related to the corrosive brake fluid that they replaced for their campaign tl6. Under hyundai's recall campaign 114, the hecu system should have been inspected and repaired or replaced in addition to changing the fluid. Hyundai merely replaced the fluid. This has caused a dangerous situation with my braking system that could have been avoided.
