Hyundai's forward collision warning light is on and won't allow me to use cruise control. I've tried cleaning the area, but still won't turn off. It did turn off for about an hour and while on the freeway using cruise control it came back on.

Federal Safety Recall Fraud and Vehicle Endangerment Report Vehicle: 2022 Hyundai Elantra Blue Hybrid | Involved Dealerships: Earnhardt Hyundai North Scottsdale & Larry H. Miller Hyundai Peoria This complaint documents severe federal safety recall fraud and mechanical endangerment by authorized manufacturer franchise dealerships. In April 2025, Earnhardt Hyundai took physical possession of my vehicle for a federally mandated Hydraulic Electronic Control Unit (HCU) braking/cruise control safety recall. Staff verbally verified the recall was complete, but the physical invoice and subsequent written email admission from Service Drive Manager [XXX] confirmed the safety repair was completely omitted with "no excuse."To resolve this braking risk, on April 22, 2026, I brought the vehicle to Larry H. Miller Hyundai Peoria to have the uncompleted HCU safety recall corrected. Subsequently, on June 17, 2026, I returned to the Peoria facility for a warranty deck lid repair and a scheduled oil change.Upon releasing the vehicle on June 17, the Peoria service department actively jeopardized my hybrid engine integrity by installing an incorrect, out-of-spec oil fluid weight (5W30) and releasing the vehicle with a completely loose, unsealed engine oil cap. This gross negligence forced me into a dangerous 140-mile high-altitude mountain highway transit ([XXX] to Flagstaff) with a compromised engine bay, creating an immediate engine fire hazard and risk of sudden highway power failure. The loose cap and incorrect fluid were independently verified and caught on video by Milestone Auto Repair in Flagstaff.The manufacturer's franchise network is falsifying federally mandated safety recall records and releasing vehicles in life-threatening, non-compliant conditions. I'm requesting an immediate the federal safety agency investigation on both dealerships. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 the federal safety agency 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 the federal safety agency 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 the federal safety agency investigators.

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.

For the past 2 years my Forward Safety System light on has been on in my car. It has turned off and back on repeatedly but has now been on for about 6 months. Hyundai dealerships are estimated a week or two of labor to fix which is extremely expensive for rental cars and outlandish that I bought this brand new and it is already giving me issues. No damage has been had to the car in any way.
