On September 22, 2022 while traveling at about 65 mph on state highway 57 in CA, I came upon a sudden group of cars hitting their brakes and had to slam on my brakes but my 2010 Genesis Coupe did not stop and I had to swerve into an entrance lane on my right to avoid a serious collision. Fortunately there were no cars entering the highway on that entrance. I was then able to drive a short distance home. On May 26, 2022 I had my car serviced including the brakes by Service Auto Care and my car gave me no brake problems until this incident. On September 23 I brought my Genesis Coupe to Service Auto and explained what happened. The brakes worked fine on the way to the shop. They tested the brakes and said that the ABS module was defective but it was just put under a 15 year extended warranty by Hyundai on May 19, 2022 and to take it to the closest dealer. …
The brakes on my 2010 Genesis Coupe suddenly stopped working while on the freeway, luckily I was able to swerve into the carpool lane and avoid an accident. Upon taking it to Tuttle Click Hyundai I was told a master technician had to review it, which would cost $200 just to look at it. When the technician looked at the car, I was told it needed a new Brake Booster. Hyundai apparently no longer makes this part so the dealership had to locate an aftermarket replacement which costs about $1,100. I did note to the dealership that there was recalls on other 2010 Genesis cars for similar issues, but was told the recall was for the sedans, not the coupe and that they/Hyundai would not cover it. Upon installing the brake booster and bleeding the brakes, it was found that I also need a new ABS Module, which will cost up to $4,000 to find and install. …

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. [redacted]
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.
As I was driving down a major street traveling around 35 MPH, the car in front of me began to stop. As I began to apply the brakes, my car's pedal went to the floor. I pumped the brakes a few times and began to get some pressure, but I was not able to stop in time before rear ending the car in front of me. I never knew what the issue was and I couldn't get the problem to duplicate, but the brake pedal was soft since that day. I have changed the pads, and rotors, so those are not the issue. This week, my fuel pump went out and I took the car to the mechanic for that issue. My mechanic informed me that the car needed an ABS pump. The dealers are well aware of the issue because when we checked the price of the part ($2600), the parts agent immediately knew the problem. There are numerous complaints online about the exact same issue. This is truly a safety issue for these cars. …
