2022 HYUNDAI Elantra

I am reporting a safety-related defect involving the vehicle’s infotainment and forward safety systems. When this occurs, the vehicle also shows a “Check Forward Safety System” warning message. Diagnostic trouble code C162078 is triggered, indicating a front radar out of alignment. As a result, critical safety features such as Forward Collision-Avoidance Assist, Smart Cruise Control, and other radar-based driver assistance systems are disabled. This issue creates a significant safety risk because the driver is not alerted to potential forward collisions and cannot rely on active safety systems. The blank infotainment screen also prevents access to vehicle settings, warnings, and camera functions. In South Korea, this same defect has resulted in an official recall and free front radar replacement and calibration. However, in the United States, customers are not covered under a recall and are required to pay out of pocket for radar realignment or replacement, even though the issue is identical and a lot of time the issue came back 3 months later and customer have to pay out of pocket once again to fix the same issue. Many owners report receiving official recall notices in other markets, while U.S. owners must independently diagnose the issue. Dealers often state that the problem may be caused by radar misalignment after a software update or system fault. In some cases, cleaning or recalibration temporarily resolves the issue, but in other cases, full radar replacement is required. This inconsistent treatment places U.S. consumers at a financial disadvantage and allows a known safety defect to remain unresolved. I am requesting that NHTSA investigate this defect and require the manufacturer to issue a U.S. recall with free repair, calibration, or replacement, consistent with actions already taken in other countries.

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.

I was pulling into a parking spot, moving very slowly, and the car suddenly accelerated. I’m not sure if it was the brakes only because I was slowed down and preparing to stop. I was lucky that I only went into a PVC fence and no one was injured. There was no indication of any sort of a possible problem. No one looked at it because I had no idea that that could be done, and I wouldn’t know where to go.

The car now shows a warning "Check Forward Safety System" and cruise control, understandably does not work. I have not had any collisions or accidents for this to occur. There seems to be no recall from Hyundai, however, this appears to be a safety issue that needs to be addressed by Hyundai.
