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.
Brake system failure. Brake pedal and goes all the way to the floor. Hyundai dealership explained that the HECU has failed. In 2014 there was a recall on this car for this issue, Hyundai Recall 114. This recall was for "GENESIS SEDAN HECU INSPECTION AND BRAKE FLUID REPLACEMENT". The known issue is that the part breaks down over time and just changing the brake fluid doesn't stop the corrosion process. The HECU part should have been replaced and not allowed to degrade further as it has now done on my vehicle.
Re: [redacted] It has been 6 months since a recall notice was sent indicating: FIRE RISK WHEN PARKED As of 3/9/2024, the recall is still marked: REMEDY NOT YET AVAILABLE This is unacceptable. What are my options to get this resolved immediately? [redacted]

I need this car repaired or repurchased by Hyundai. 10 Moinths is far too long for a repair.
if the brakes are hit hard and ABS engages, the pedal immediately goes soft and stays soft braking is impared bu 50% until the ABS module resets itself randomly but only after parking the car for a while. this has happened 2X to my car and there are multiple reports on the genesis forums about the exact same issue
ECBM Electronic Control Brake Module malfunctioned at 78,500 miles and dealer could not fix because computer would not read anything. Cold have caused a serious accident if it had happened when driving.
