2011 Hyundai Genesis: ABS light or ABS activating

Filed Dec 5, 2023 · Brakes, Driver assistance · IN

The HECU has been malfunctioning in my car for over a year now. It is an open recall for my make, model and year of car. I took it to Bob Rohrman Indy Hyundai and they diagnosed the failed part. This part affects my ABS. There are currently two warning lights on one for the ECS which is the traction control stabilizer and the ABS light is on. Meaning the use of the breaking system is limited and not working properly. I have asked the corporate Hyundai to uphold the recall warranty but I was advised they would not cover this because my vehicle has a rebuilt title. I drive my vehicle on a daily basis and I’m terrified of my brakes going out. The corrosion from the fluid is what causes the HECU to malfunction and it is so scary to think about. This problem was diagnosed and first reported to my his dealership on 6/23/2022.

My 2011 genesis sedan (4.6l v8) has an increasingly soft, spongy brake pedal past year or so. This occurs while driving in/out of my neighborhood, on busy nj highways, and when parked with engine running. Had rotors, pads, master cylinder and brake fluid replaced recently (~2 months ago; $1200; receipts available). Did not solve the problem. I feel unsafe driving the car and putting me/other drivers at risk. From researching the problem, including recently learning about the recall of 2009-2012 models for brake problems, I am guessing that either the brake booster and/or ABS brake module are failing. I bought the car new and am its only owner. Car has only 73,000 careful miles on it. I'm reluctant to spend any more money. What can I do?

My 2011 hyundai genesis is experiencing braking failure. I have almost had accidents due to my car's inability to come to a stop in a reasonable time, especially when following vehicles that come to a sudden stop. The pedal depresses almost to the floor and is very spongy. The problem is intermittent but consistent. I researched the issue and found that there was a recall related to this issue, but for some reason, hyundai excluded my VIN despite it falling within the manufacture period of hyundai cars experiencing the issue. I took the car to the hyundai dealership and they diagnosed a failed ABS system, specifically stating that the internal seals of the hecu (ESC unit) were worn causing poor sealing. This may be related to the corrosive brake fluid that they replaced for their campaign tl6. Under hyundai's recall campaign 114, the hecu system should have been inspected and repaired or replaced in addition to changing the fluid. Hyundai merely replaced the fluid. This has caused a dangerous situation with my braking system that could have been avoided.

I purchased my used pre-certified hyundai genesis 20 11 car in february 2014 and shortly thereafter I found that my brakes which originally were firm would go down to the floor or nearly to the floor within 6 months I did some research on the car and found that in 2013 hyundai corporation issued a recall on the ABS system do 2 corrosive brake fluid that was could potentially corrode the ABS system and 2013 the brake fluid was replaced on my car prior to my purchase. However hyundai did not inspect whether ABS systems had already been damaged by this corrosive brake fluid and merely replaced it my car has an ABS system that has been tested and it fails. The brake pedal on my car nearly touches the floor and it is difficult to stop the car safely. I was driving in the rain recently and just missed hitting a car that stopped suddenly.

The federal safety agency campaign number: 13v‑489 hyundai notice 13-01-006 campaign 114. I have had my brake pedal go almost all the way to the floor 3 times now in the last 2 months. This is extremely dangerous and luckily I have been able to stop in time not to cause an accident. Review of the hyundai forum indicates that my ABS module or hydraulic electronic control unit (hecu) is failing. Brake pedal feel will then go back to normal after I restart the car several times. I have an appointment with dennis hyundai in columbus, oh today and I hope they are willing to replace the ABS module for free as required.

After a brake job, I took the car back to say that the pedal was going to the floor. I was told I had a leak in the master cylinder. Got that repaired. After having the master cylinder repaired, I am now being told I have to replace the hydraulic electronic control unit (ABS, hecu). Did some research, and saw that this was a recall issue for 48,000 genesis between the years of 2008 and 2012. Issue seems to be caused by brake fluid corrosion. My car was not part of the recall. I reported the initial issue at 64,000 miles. Car is now at 80,000. It has been sitting at the dealership because it had an engine replaced covered under warranty.

While the automobile is in motion the brake pedal is mushy to the point that it almost reaches dead bottom before engaging the brakes. This happens both on the highway and on the street no matter the speed. Repair shop states that its the ABS hydraulic module is defective. Hyundai dealer states that it is for the fluid recall. It is not fixing the brakes.

Tl* the contact owns a 2011 hyundai genesis. When applying the brakes, the brake pedal traveled to the floorboard without stopping the vehicle. The contact had to pump the brake pedal in order for the vehicle to stop. When the vehicle was stopped with the brake pedal depressed, the pedal would lower unintentionally; however, the vehicle would begin to slowly move forward at the same time. The contact took the vehicle to a certified mechanic who diagnosed that the electronic control system and ABS failed and needed to be replaced. The contact notified the anderson hyundai dealer and was informed that the vehicle was not included in the federal safety agency campaign number: 13v489000 (service brakes, hydraulic). The vehicle was not repaired. The manufacturer was made aware of the failure and reiterated the dealer's diagnosis. The approximate failure mileage was 118,000.
