2022 HYUNDAI ELANTRA Service Brakes Problems

My vehicle experienced a sudden and complete brake assist failure, including the emergency brake. I was unable to stop the vehicle, which directly resulted in a collision. Prior to the crash, the car showed no warning lights. After the accident, I had the vehicle inspected at the Hyundai dealership. The dealership stated they could not reproduce the failure and “found no issues,” which contradicts the symptoms. Since the crash, I discovered two Hyundai Technical Service Bulletins that directly match the failure I experienced: TSB 23-01-036H-1 (Relates to HECU/Electronic Parking Brake failure) TSB addressing DTC C1620 (Relates to FCA Sensor/Automatic Braking malfunction) These TSBs relate to brake assist malfunction, emergency brake concerns, and similar stopping failures. The dealership did not disclose these TSBs, did not apply the corrective procedures, and cleared the car as having “no defects.” The dealership wrote “could not reproduce concern” and “no problems found,” despite the vehicle having just been in a brake-failure crash. This brake failure created a major safety risk with potential for severe injury or fatality. I am reporting this because the defect appears unresolved, the dealership denied it, and the TSBs show Hyundai is aware of brake-related issues. I request that NHTSA investigate this brake-system failure as part of a potential manufacturer safety defect. The vehicle is currently secured at the dealership (Lithia Hyundai, Las Vegas) and is available for inspection upon request by NHTSA investigators.

Intermittently while driving the vehicle will suddenly engage the traction control (TC)/electronic stability control (ESC). The light flashes for a short period (probably no more than a couple of seconds) and the car slightly jerks to the right. A loud noise is heard when this happens and the brake pedal shakes. Then the light will stop flashing and the car will begin operating normally again. Typically, the problem will reoccur shortly after it happens. I took the car to a dealer, and the dealer was unable to replicate the problem. The service manager stated that there were no codes and no history, and without a code the problem could not be diagnosed. This problem occurred multiple times over the last few months.

While driving highway speeds (65mph-75mph) the emergency braking system randomly activated causing my car to slow to almost a halt and swerve itself in the middle of the highway almost causing multiple accidents. It has happened 2-3 times over the past 2-3 months. Brought to a dealer and it could not be "duplicated" so I was sent on my way worried about this car.

My daughter was driving the car to work. The car accelerated even thou her foot was lightly placed on the gas pedal, it was like pressing the gas pedal to race the car. This happened 4 times on her 4.5 mile drive to work. When she was turning into the parking lot, she had her foot on the brake and the car accelerated again which scared her as she didnt want to crash into the cars in front. I read a lot of such complaints on the hyundai forum. I talked to the dealership service mechanics and they say that they will have to replicate it. This is the first time this has happened in the last 2 years. The contact stated that this information is incorrect and applies to their other VOQ 11525448 for their 2021 Hyundai Elantra. The 2022 Hyundai Elantra has issues with loss of power.

I bought my brand new 2022 Elantra in July of 2021, the only problem I have experienced is the brakes make a sort of wailing noise. It's not a screeching noise as if the brakes need to be changed or that the rotors are worn or brake pads are low. It is not a sound I've heard brake make before and it typically makes the sound when in reverse and slow speeds. I was a mechanic in the United States Air Force for 16 year so I know a lot about mechanical issues so a year old car certainly shouldn't be making these kinds of sounds.

I drove my vehicle to the store, parked and went in to the store to get some things. When I came out and started the car several things were wrong with the car. The power steering was not working, the RPM gauge didn't work at all, the back up camera also was not operational. The check engine light was on, the forward collision light was illuminated. I was able to drive it home but that was a sketchy drive home. The next morning I got in the car and started it up no problem, none of the issues from the previous day were there, the power steering worked perfectly and everything was fine. I still drove it to AutoZone to get it check with a scan tool, and when I did the scan tool didn't come up with any faults. This all happened about two weeks ago. Hopefully the problems don't come back. vehicle mileage is 15,000 and I've had the car for almost a year so whatever it is better be covered under warranty. I also have been having a kind of wailing sound from my brakes when I slowly reverse, It's a high pitched squeal that is usually heard when the brake pads are worn. It sounds like a deeper kind of wailing sound. It actually comes and goes and never does it in normal drive only in reverse, If anyone else has experienced this please let me know.
