February, 2024 - brakes "soft" at times, seems not catching unless stepped on almost to the floor. I brought it to the dealership same day. Since I did not have an appointment, a test drive was done and was told it was working fine and let them know if the brake warning lights will turn on. No record of this was noted. March, 2024 - I had to bring it back because the brakes feel like it will quit as I have to really step on the pedal to the floor before the car will slow down. The master cylinder was changed. Multi-point inspection was done. I got the car back March 14, 2024. April 12, 2024 - I had to bring it back because of the brake and ABS lights on the instrument panel lighted up. I was told it's the HECU that's the problem. I had to drive back the car to home because of the quoted cost of $3,266.58 estimate that I have to make a decision of. This was on April 23, 2024. I was told that the ABS module may not work in event of inclement weather or quick stops. A multi-point inspection was done prior to release of vehicle. I never received a recall on the Hyundai HECU. It was only when I researched it after I got the car back. I made it known that I want to be sure I will not get in an accident due to the brakes not working. I was informed that I can drive it but be mindful of the ABS module not working in cases as noted, that the lights were alerts but could be a problem later on. What is my recourse since I did not receive any recall notice? I was trying to fill up the complaint form and it said that the car is impacted by the HECU complaint. it will not let me complete the form. It was frozen on the reimbursement requested. The dealership never did inform me of the recall. I bring this car to this dealership for maintenance and repairs.

The ABS module just started smoking today. Smell of burning breaks. We was driving in the city and stopped at a mall and noticed the smoke coming from behind the driver side wheel.

The sensitivity on the alarm system is way off. I can't even set the alarm because if a semi drives passed it, the alarm goes off. If a cat jumps on it, the alarm goes off. If a strong breeze goes by and a twig drops, it goes off. Even though the local hyundai repair people know what is wrong, they still want to charge an arm and a leg. For something that isn't my fault. Just recalibrate your equipment. You have the computers to do so because your equipment has done it before. Maybe fix it?

I am concerned about why my VIN was not put in with the recent recall of the ABS and ESC and has been shorted or drained battery and my vehicle has shut off and the electrical has caused problems with my break lights at one point. I have replaced my ABS sensory 2 times already and the light still apears.

When driving the vehicle, the eps light would arbitrarily turn on and go away when the ignition key is cycled off and back on. When the light comes on, it immediately becomes difficult to steer. The car reverts to manual steering mode and requires significant amount of effort to control. We have had the eps light turn on multiple times without warning while driving and putting us in dangerous, unsafe conditions on the road. Recently, the eps light is staying on and not going away. We visited the local dealer to report this issue and their diagnosis resulted in error codes related to the steering angle sensor-electrical, torque sensor main signal fault, ecu (brake system) hardware error, can time-out ems, and motor. When asked, they were not willing to perform an evaluation as per the technical service bulletin. They recalibrated the steering angle sensor and stated that if the problem reoccurs, we would need to return to the dealership to replace the steering column (part number 56310-2h250 as1) and pay full cost of repair (part and labor). This part number is listed as a replaceable item per the technical service bulletin. Please note that the dealership performed an eps s/w chk/ecu upgrade in 2015 when no issues were present and refuse to further assist when the issue is present when the recall campaign information letter in march 2015 clearly states that the final remedy has not been developed at this time. The diagnosis shows that a faulty part was installed by the car manufacturer, as stated in the recall, and the dealership is refusing to address the actual issue. Instead of solving the problem, they insist that we drive this potentially unsafe vehicle until the issue reoccurs. This is a safety related concern as there is no warning to when this issue will occur. Their recall notice states that the eps problems could result in an increased risk of a crash.
