Brakes are spongy/soft - My car has been inspected by a Hyundai dealership and an ABS control module replacement has been recommended at cost of $2901. A safety recall campaign was issued in 2012 to include "certain 2009-2012MY Genesis (BH) produced from April 30, 2008 to March 28, 2012 (Recall #114). On May 9, 2022, TSB #22-BR-001H-1 was issued. My car's VIN indicates that my car was produced March 30, 2012 and the repair under the "extended warranty" has been denied because my car was produced two days later and therefore not included in the safety recall. I have reached out to Hyundai and I have a case manager assigned to me.

While in route to the dealer for one issue, my smart cruise light came on. I reported this to the dealer upon arrival and they ignored. They repaired one item under warranty in which I though took care of both. By time I left, allowed the car to warm up; the smart cruise light came back on. I contacted the dealership & asked them what happened to this 2nd issue. They scheduled an appointment and I was informed by that time and visit; the warranty had expired and I will have to pay $4200 to repair the problem that they now see. I had also been complaining about my ABS/ESC/auto hold lights were constantly flashing, now they remain solid. It causes the vehicle to jerk when in reverse. I have read about several recalls regarding issue. The situation has gotten worse and I was told it is now leaking brake fluid. The dealership has now given me a price totaling $7000 to repair or purchase a new vehicle. This is money I cannot pay and I know my vehicle was still covered when the problems/ recalls started. These incidents occurred on several dates.

The brake pedal of my car is soft and deep, and the braking is not done properly. After about a month and a half, the symptoms appeared and I changed the brake pads. Every day driving is a continuation of tension. I went to the designated service center and inspected it. During the re-run, the same phenomenon continued, and after a week again, I had to change the ABS module. How much of an ABS module does it have grounded like a brake pad? I can't understand it. I looked at the internet and the model I was riding was subject to recall.

On october 23rd, 2019, the brakes on my 2012 hyundai genesis r-spec sedan suddenly failed with the brake pedal going all the way to the floor before the vehicle eventually stopped luckily avoiding an accident. I was driving on the highway. The vehicle has 79k miles. I then took the car to the hyundai dealer in st. Louis park, mn and they determined that the brake master cylinder was faulty and replaced. The diagnosis and repair did not fix the issue as the brake pedal was still spongy and going to the floor intermittently. I will be taking the car back to the dealer to have them fix it correctly. While researching the issue, I have found that multiple other owners of the same car have experienced this issue and the dealer had to replace the ABS hydraulic electronic control unit (hecu) as it contained corrosion within the unit due to bad design which causes hydraulic braking failure to occur at any time. This campaign/recall below outlines the issue which I am going to present to the dealer to fix correctly as I am still under warranty. To me, this is a life or death type failure and could result in injuries. Hyundai should be responsible for replacing all ABS hecu before lives are lost for all 2009-2012 hyundai genesis, not just some vins that they deemed troublesome. They should take responsibility for all cars and immediately contact their owners.

Following a hard turn which activated my electronic stability control (ESC), I lost all pressure in my brake pedal and it sunk to the floor. This is following a near-accident in which I had to engage my ABS system by slamming on the brakes to avoid an accident. Ever since that ABS activation, my brake pedal has not felt the same. It takes more effort to stop now and you have to push the pedal farther than usual to get brake activation. I can recreate the problem by getting the ESC to activate again if I spin the tires on a hard turn. Immediately after doing so, I will no longer have any braking power or pedal pressure. Hyundai refuses to accept responsibility for this because even though my vehicle is within the affected production years, they claim my VIN does not qualify for the recall. The recall was campaign 114 which eventually turned into a mandatory recall. The potentially affected years range from 2009-march 28th 2012. My vehicle was made january 10th, 2012. Therefore it should qualify but they claim it will not. I am afraid for my safety and hyundai needs to own up to their mistakes and fix my problem before I die from it. The 3 instances I've had the issue have all occurred while making a hard right turn with low traction and the ESC light flashes meaning the ABS was indirectly activated. After this turn and ESC activation, there will be no pressure in the brakes until it gets pumped several times. Sometimes I will have no brake pressure in the pedal until I've stopped 3 or 4 times and pumped the brakes.
