2010 Hyundai Genesis Coupe Brakes Problems

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. Another user posted this same issue to the NHTSA in October 2022.

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 dealer, Russell Westbrook Hyundai of Anaheim told me only the sedan was covered. This dangerous defect could occur at any time and cause a severe accident. I hope this report is helpful to the NHTSA and the defective part is replaced without charge. The dealership charged me $205 for an estimate, then wanted $2200 to re-do the brakes and then approximately $4000 to replace the ABS module. I have documents to back up everything I have presented.

HYUNDAI MOTOR CORPORATION SHOULD DO WHAT IS REQUIRED TO GET THE CAR THEY SOLD ME TO BE IN SAFE OPERATING CONDITION, AND THEY REFUSE TO DO SO. *TR

I BEGAN HAVING THIS ISSUE 10 DAYS AGO WITH MY 2010 GENESIS COUPE. THE CONCERN I HAD WAS NOT ONLY WAS THE INTERIOR FLICKERING BUT IT RESULTED IN MY RUNNING NIGHT BRAKE LIGHTS NOT WORKING. I TOOK THE CAR TO THE DEALER I'M AT 62K MILES JUST OUT OF WARRANTY. THEY RAN DIAGNOSTIC AND THOUGHT IT WAS A LOSE BRACING FOR THE WIRES. I PICKED IT UP AND THE ISSUE BEGAN AGAIN. I TOOK IT IN 4 DAYS AGO THEY THEN SAID IT WAS A FUSE SWITCH ISSUE AND REPLACED IT BUT THE ISSUE CONTINUED. THEY THEN SAID IT MAY BE A FUSE BOX ISSUE COUPLE OF HUNDRED $$ OR WORST CASE A MAIN ISSUE WITH TOTAL WIRING FROM INTERNAL FUSE BOX AND FUSE BOX IN THE ENGINE AREA WHICH COULD RUN $2K! BUT NO DEFINITE ANSWER TO WHAT WAS CAUSING THIS. THE HYUNDAI REPRESENTATIVE SAID THEY EVEN HAPPEN TO HAVE A SENIOR ELECTRIC ENGINEER ON LOCATION THAT DAY AND HE COULDN'T PINPOINT EXACTLY THE PROBLEM. *TR
