Brakes Failed Problems of Hyundai Sonata Hybrid

I had two case numbers with Hyundai related to my brakes and fuel efficiency; the first was Hyundai consumer affairs case#: 12894630 and the second was Hyundai consumer affairs case#: 15512885. Both cases were closed prior to me having any say in the decision (email/phone records show this). After my braking unit fails for the second time and I noticed a significant drop off in fuel performance (mpg), I asked for another Hyundai rep to test my fuel consumption. When the results proved to be better than I had ever seen my car perform, ever, I asked for the rest specks. This was escalated to Hyundai corporate, who responded �unfortunately your case manager cannot provide any TSB's because it is proprietary information. As far as warranty extension, regrettably that is not an option. However, if you were to have brake concerns outside of warranty, Hyundai will review for goodwill if the problem is something that was previously repaired under warranty. � this answer failed to consider the mileage I was already losing in my hybrid which performed worse than a non-hybrid model whenever the brakes were failing. I made good faith efforts to report my problems in the hope Hyundai would resolve them.

On 05/10/2018, I noticed severe vibration and clunking in steering wheel. Brought vehicle to Hyundai dealer and they replaced the flexible coupling in the steering column due to wear. On 08/08/2018, I brought the vehicle to the Hyundai dealer for routine service and asked them to check the brakes as I experienced an intermittent loud squeaking from the brake pedal. They were unable to diagnose the problem. On 09/25/2018, I attempted to start the vehicle from a stationary position and when I depressed the brake, the pedal went all the way to the floor and a warning came on the dash advising me that the brakes had failed and I needed to stop immediately. I shut the vehicle off and then attempted to restart. Upon restart the warning condition did not reoccur. Vehicle towed to Hyundai dealer for diagnosis. I was advised that the issue seems to have corrected itself and the brake system simply needed to be recalibrated.

Tl the contact owns a 2013 Hyundai Sonata Hybrid. While driving 10 mph, the brake pedal was depressed and traveled to the floorboard. The contact attempted to stop the vehicle by shifting the gear shifter into reverse, but it failed to shift from drive. All the warning indicators illuminated. As a result, the vehicle collided with a street sign. The contact sustained back injuries that did not require medical attention. A police report was filed. The vehicle was towed to the contact?s home. The dealer (keyes mission hills Hyundai, 10240 sepulveda blvd, mission hills, mission hill, CA 91345, (818) 221-4000) was contacted and informed the contact to have the vehicle towed to an auto body repair shop. The manufacturer was made aware of the failure and informed the contact to take the vehicle to a dealer for determination of the brake failure. The contact stated that the vehicle was towed back to the dealer, but a failure could not be determined. The vehicle was not repaired. The approximate failure mileage was 73,000.

I was approaching a red light while driving in city traffic, traveling 35-40 mph, when I took my foot off the gas to slow down and prepare to stop for traffic and the red light. When I applied my brakes, the pedal went all the way to the floor and the vehicle would not slow down or stop, warning chimes began to go off. I swerved to avoid hitting several vehicles in front of me as I applied the emergency brake, which only gave enough resistance to slow but not stop the car. I was able to get my vehicle to slow to a stop when it started to roll backwards, the only way I was able to keep the vehicle from rolling backwards was to shift it in to park. Once I was safely stopped, I observed in the information notification center a brake system failure message, which was the reason for the warning chimes. I contacted Hyundai roadside assistance and they towed it to the nearest Hyundai dealership. This is the 2nd complete brake failure in 6 months, 9th time in and over 30 days, and counting, for brake issues.

When the car was started a beeping alarm sounded with a warning stating that there was a brake failure. Yellow triangle with black exclamation point also warning me not to drive. Brakes had severe grinding when trying to move. This is the second time that this has happened to the car. First time was approximately a year ago. I was originally told then that there may have been a hydraulic problem but then told that it was a bad connection somewhere. Waited approximately 15 minutes and car starts with out a problem. My fear is that the brakes will lock or fail while I'm driving on the highway.

I was driving at about 55 mph on the expressway with the cruise control engaged. Suddenly there was a loud dinning and the panel on the dash flashed "hybrid safety warning", "brake failure". The care would not accelerate. I was able to pull over onto the shoulder. The car would not go over 5 mph. I pulled off of the expressway as best I could. I then shut the engine down. I restarted the engine and the warning was gone. I took side roads home, but the warning did not return. The total failure of engine power was a very dangerous situation. I took the car in to the dealer on 4/21/14. They have not returned it to me. As of today 4/24/14.

As I was gently applying my brakes in heavy freeway traffic, going about 50mph, the brake pedal became soft and dropped to the floor. The brake failure warning light also started to flash and chime. I swerved off to the side of the road to avoid hitting the car in front of me and plowed through some plants on the shoulder prior to coming to a stop with my parking brake.
