Brake pedal has been intermittently low/spongy and has progressively gotten worse. During these events, the brake pedal goes nearly to the floorboard, and braking power is weak but will typically function after pumping the pedal repeatedly. Stopping or slowing in an emergency situation may not be possible. There is no manual emergency brake. No trouble codes found, and no warning lamps illuminated related to the braking system. Dealer diagnosed faulty antilock braking system (ABS) hydraulic electronic control unit (HECU). This exact defect is addressed in Warranty Extension TXXP: Hydraulic Electronic Control Unit (HECU) [XXX] Hyundai rejected this under the warranty coverage because the vehicle build date is approximately 2 weeks beyond the date range in the TSB. Subsequent web searches revealed replacement parts were available for production in late XXX. The TSB's affected date range ends on XXX. This vehicle was produced on XXX and was not included in the recall notifications. It is not known if a complete stock purge was performed on the production line or if parts were continued to be installed until old stock was depleted. Other vehicles outside of the TSB stated production date range may also have this latent critical safety defect.

What owners say
UNKNOWN, The car lose electricity, shutting down by itself, when I press start engine, or when I shut down engine, recently car shuts off while I drive it on highway, it didn't start until I jump start it, also it shows lights of ABS, and brakes auto hold, cruise control not working.
2013 Hyundai Genesis sedan (BH) is experiencing the intermittent soft brake pedal and reduced braking pressure that matches the TSB 22-BR-001H for the HECU on 2009-2012 Genesis sedans. I took it to the local dealership but their mechanic said they could not recreate the condition. The ABS and ESC lights have both come on at times but I was told there are no stored codes. The tech noted that the rear driver brake pads appeared to have some additional wear indicating additional ABS activity or sticking brake pads. I paid to have a brake service performed and the brake fluid flush/replacement performed to eliminate the concern of any air entrapment or sticking brake pads. However, this work did not resolve the problem. The shop said there are no open recalls nor brake related TSBs for the 2013. They have not fully tested the master cylinder, booster, nor the HECU. With no support for the model year, despite the MANY issues reported for this problem on the 2013 and Hyundai's knowledge of these problems form 2009-2020 model years, this TSB should be expanded for additional model years and likely should be considered as a recall repair due to the safety risk of brake pressure loss.
After Hyundai performed a recall service on my vehicle, the radiator hose burst while I was driving on the highway, causing the engine to fail completely. Smoke came from the engine compartment, and I had to pull over immediately with my family to avoid a serious accident. Before the recall, the vehicle had no issues and ran perfectly for three months after purchase. The problem occurred only a few days after the recall service, which included work on the ABS module. Hyundai refused to take responsibility, even though this failure happened right after the recall repair. The dealership and manufacturer did not inspect the vehicle properly and made their decision based only on a phone conversation. This is a severe safety concern because the engine failed suddenly on the highway. I believe this failure is directly related to the recall work performed under the federal safety agency Recall #21V160000, which is still listed as incomplete on the federal safety agency records.
I have had intermittent brake pedal to the floor issue for the past two years. It started off occasionally, but turned into daily. It's very very dangerous as the brakes barely work. To remedy, I had the brake rotors and pads changed, brake fluid flushed. Did not fix the issue. Had the Master Cylinder replaced and it fixed the issue, but then two days later my brakes started binding (opposite problem). Replaced the HECU / ABS Module and still have the same issue. Now the car is not drivable because the brakes are binding. I called a local Hyundai Dealership to see if they would try a goodwill HECU service, since previous years Hyundai Genesis were recalled with the exact same issue, but they said they would not do it for me. So I am trying to work out the issue through independent mechanics. This is a very dangerous issue as the brakes do not work and is a widespread issue affecting multiple BH model Hyundai Genesis owners.

Brake pedal has to be pushed harder than normal to get brakes to engage. Dealer has diagnosed problem as faulty ABS module which is not considered as part of recall for CCU unit on other hyundai models
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.
The contact owns a 2015 Hyundai Genesis. The contact stated while driving through heavy rain, the ABS warning light intermittently appeared on the instrument panel. Recently, the contact stated that the ABS warning light remained illuminated upon starting the vehicle. Upon investigation, the contact discovered the federal safety agency Campaign Number: 21V160000 (Service Brakes, Hydraulics) which was linked to the failure. The dealer and the manufacturer were notified of the failure and confirmed that the vehicle was not included in the recall. The vehicle was not repaired. The failure mileage was approximately 30,000.
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.
