general problems of the 2010 Hyundai Genesis

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.

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 stated that while driving his vehicle, his brake system started to make noise and became unresponsive. The contact stated that he then drove his vehicle to the dealer to have his brakes changed. The contact stated that the dealer changed both brakes and, rotors , front and rear, however the failure still exist. The contact stated the dealer advised him of the recall on the same year, make , and model vehicle that was experiencing the same failure NHTSA campaign 13v489000 (service brakes,hydraulc). The contact stated that he was advised that the hecu needed to be replaced. The contact stated that he then contacted the manufacturer who advised him that his vehicle was not apart of the recall. The contact stated since then his vehicle remains with the dealer who adivised him to contact NHTSA. The mileage failure was 90,000.

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. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Spongy brake pedal goes to floor as in recall 13v489000 with other vehicles of this make and type, but no recall on this vehicle all other repairs standard repairs not clearing problem.

Brake pedal one 2 occasions while applying the brake went all the way to the floor with very diminished stopping power the first time was on the highway a few months ago and the second time this happened was December 31 2017 I drove the car home and did not drive it till Tuesday, Jan 2nd, 2018 when it drove it slowly to the dealer on the way there the pedal got firmer but still spongy not normal the dealer can't find the problem and will not help me I'm afraid to drive the car.

Background: am original owner of this 2010 Hyundai Genesis that was purchased July 31, 2010 and that currently has less than 35,000 miles on it. Issue: unexpectedly, the brakes became "squishy" (I. E. Brake pedal depressed a long distance before engaging brakes). Advised by Hyundai dealer that it is a faulty hecu unit and needs to be replaced for $3,800. Note: the brake fluid was replaced in April 2013 and the hecu unit was supposedly inspected in January 2014. I believe these were done in response to prior recalls. That said, upon some further reading on the internet, I am under the impression that when this problem was previously identified for recall, the recall should have resulted in my hecu unit being replaced, not just inspected. I intend to raise this issue with the Hyundai dealer and, hopefully, Hyundai will stand behind the replacement of the hecu unit without charging me.

Partial loss of braking - while traveling down the highway at 45 mph the vehicles in front of me abruptly slowed down requiring me to quickly apply my brakes. Upon application of my brakes, I started to slow down and then the brake pedal suddenly released, providing limited braking. I continued to push the brake pedal towards the floor and the vehicle came to a stop but it required a longer stopping distance than normal.

Breaks failed. Taking exit from highway and the car wouldn't stop as the breaks would work. Was very fortunate to have found gap between two lanes and avoided a major accident. Dealer confirmed the breaks failed and there have been numerous break failures reported with genessis. Had recently got breaks checked and was told 'every thing is fine'. Question is why didn't Hyundai do a recall and proactively replace my break system? one whole day of suspense about how much it will cost me. . . And I was told Hyundai would cover the cost of replacement as it was a known problem. Dealer called it 'goodwill warranty'.

The contact owns a 2010 Hyundai Genesis. While depressing the brake pedal and attempting to stop the vehicle, the brake pedal traveled to the floorboard. The contact was able to stop the vehicle. The vehicle was towed to the dealer where it was diagnosed that the hydraulic electronic control unit failed and needed to be replaced. The vehicle was not repaired. The VIN was not included in NHTSA campaign number: 13v489000 (service brakes, hydraulic). The manufacturer was notified of the failure. The failure mileage was unknown.

Attempted to reduce speed to enter neighborhood street and brake pedal went to floor. Continued pressure stopped the vehicle. Brakes could be pumped up and continued to stop the vehicle, but with seriously degraded braking capability. An accident waiting to happen.

I was driving on spring cypress rd (spring, TX) approaching state highway 249 at 30 mph, I stepped on the brakes at the intersection and the pedal went all the way down to the floor. If I didn't start pumping the brakes, I would have rear ended car on front of me. If this incident had happened while I was on the sh249 freeway, I wouldn't be here filing this report. I was able to drive slowly to the Hyundai dealer using side roads.

Brake pedal goes to the floor without much effort when at a full stop or in motion. Little to no actual braking occurs until reaching the full travel of the pedal. This is very dangerous and the dealership (burns Hyundai of marlton NJ) acknowledged it is the hydraulic control unit, but refuses to replace under the 2013 recall of the unit. They quoted me at $3,024. 50.

I had two prior incidents where partial to complete braking failure occurred previously, but the issue was only temporary (a single stop). This incident persisted for duration of my drive, prompting research into the issue (and discovery of the known abs hecu corrosion issue. I was attempting to slow and make a turn onto a sidestreet on the way to work, when the brake pedal went to the floor with minimal resistance (and limited braking effectiveness). This prompted a panicked pumping of the brakes to eventually stop the vehicle 5-10ft shy of the rear bumper of another car. After carefully testing to ensure I had some braking effectiveness, I finished the short distance to my office, noting that the pedal remained very soft, going to the floor with ease, and having limited success in stopping the vehicle. I shudder to think what would have happened had this issue presented itself at highway speeds. I have already contacted Hyundai corporate and dropped my vehicle off with a dealership for recall repair. I am hoping this incident, coupled with my manufacture date (prior to June 1, 2010 cutoff date) will justify a full abs hecu replacement under recall.

Driving about 10 mph on tight curvy country road, brake pedal went to the floor. Pumping the pedal got the car to stop. Dealer said the brake force distribution module failed, allowing brake fluid to simply bypass being sent to the brakes. This is a very dangerous failure mode; it should fail by eliminating abs but still giving full brake force. There was no indication on dash lights that anything had failed.

When driving the vehicle, the brake pedal went all the way to the floor and my brakes went totally out. It is a miracle there wasn't a crash with someone killed. There was a recall for this same issue and my recall was done last December but obviously the damage was already done and it did not fix my car. I called that dealership back today and they advised me that because the recall had been done and my car is out of warranty, that everything will be at my expense to repair. I will also have to pay to have it towed to be repaired. Hyundai should be paying for the towing, repair, and loaner vehicle as this was a major safety issue that they have failed to take care of.

1) almost hit from oncoming traffic at a stop light, when I was attempting to make a left hand turn. The signal turned yellow so I tried to turn left before I realized the oncoming car was going to run the light. I took my foot off the brake and hit the gas to make a quick turn to avoid the oncoming car. The car stalled for a second as I pressed the gas into the turn, then kicked into full power, screeching the tires. I thought this was a fluke but his same problem of "stalling" for a few seconds when depressing the brake and hitting the gas at takeoff keeps happening intermittently. This is a dangerous issue. When needing to accelerate quickly from a stop, this car has a seconds gap from hitting the gas to the car moving. I've almost been hit twice because of it. 2) the headlights switch off intermittently when using the turn signals to change lanes or turn. They flash oncoming drivers as I click down to turn them on before the turn, or when the turn signal clicks back after the turn. This problem happens almost every time I drive the vehicle with the headlights on. The lights have shut off completely for about 5 seconds while I was driving down the freeway, impairing my ability to see at night. I had to immediately pull over on the freeway in an unsafe location to turn the lights off, then turn them back on to clear the problem. 3) my vehicle had the brake switch replaced from the 2013 recall. However, pressing the brake still does not shut off the cruise control when driving down the freeway. I have to manually turn it off from the button on the steering wheel. I love this car, but I'm afraid to drive my children in it if these problems are not addressed. This vehicle is unsafe and it is going to kill or seriously injure people. Please investigate these mechanical problems and issue the appropriate recalls.

As I was exiting the highway, the brakes went almost all the way to the floor. The rest of the trip I needed to pump the brakes to enable me to stop. I took it the Hyundai dealer the next day and they said it there was a recall for the abs module. I had the dot4 fluid recall done on December 3rd 2013 (up until then I had never had a brake issue) and apparently the abs module recall came out Dec 20, 2013. The dealer replaced the module under warranty and now the car brakes fine. I just wanted to document the failure.
