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.

The contact owns a 2010 Hyundai Genesis coupe. The contact reviewed a service campaign consent letter from the manufacturer, which indicated that the hecu was to be serviced and replaced for all genesis vehicles. When the contact called the manufacturer, they specified that the Genesis coupe was not included in that manufacturer campaign. The contact stated that there was a random progressing failure in which the brake pedal was applied, but was slow to respond. The vehicle was taken to a repair shop. The mechanic drained the brakes, replaced the brake pads, and serviced the brake system. The dealer was notified of the brake system failure and indicated that the independent repair shop had not completed the repair correctly. The contact notified the repair shop and was informed that the repair was completed correctly. The manufacturer refused to service the hecu system pertaining to the service campaign, so the contact was unable to determine a permanent remedy. The vehicle was parked due to the failure. The vehicle was not included in NHTSA campaign numbers: 13V113000 (exterior lighting, service brakes, hydraulic) and 13V489000 (service brakes, hydraulic). The VIN was not available. The approximate failure mileage was 66,500.

Since purchased used from a Hyundai dealer in 2011 with just 11,123 miles & full warranty, this vehicle has had "intermittent operation of the push-button start feature, intermittent ability to remove the vehicles shifter from the park position, illumination of the ESC'(electronic stability control) indicator lamp in the instrument cluster, intermittent interference with operation of the cruise control feature, or intermittent operation of the stop lamps" as cited in campaign 110 released by Hyundai on March 29,2013. I have brought it to the dealers service department on 11 separate occasions, for the above listed issue -to two separate dealers- and while both utilized the Hyundai warranty to the fullest extent, to replace everything from my radio, to transmission modules, to wheel cylinders, none of these issues fixed the problem.when I spoke to Hyundai last week regarding recall campaign 110, I was assigned a case number, but I received a call the next day that my case was being rejected by the regional office.when I brought it to the dealer for the recall repair this weekend, they insisted that they would have to charge me for the visit, despite my complaint being the one listed in the recall.I feel that Hyundai should honor their recall and address this problem in my car at their expense until they rectify the issue cited in the recall, despite the faulty part having been replaced through my factory warranty multiple times, and prior my receiving notice of the recall. 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.

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.
