FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

I am submitting a second and more urgent safety complaint regarding the Driver Monitoring and Driver Assistance systems in my vehicle. I previously reported this same core defect: the system falsely fails to recognize my face, sounds repeated warnings, and disables driving assistance while the vehicle is moving. Despite that prior complaint, the defect remains, and the seriousness of the danger has clearly not been recognized or addressed. This defect has now placed my life in immediate danger. While I was driving, the system falsely determined that it could not properly see my face. It sounded repeated warnings and then abruptly disabled driving assistance. That sudden withdrawal of assistance created a near-crash situation. I was attentive and was not experiencing a medical emergency. The danger was created by the system’s false detection and defective response. A safety system should reduce danger. This system detected a supposed problem and made the situation more dangerous by removing the assistance that was helping keep the vehicle under control. Had this occurred beside a concrete barrier, near stopped traffic, in a construction zone, on a curve, or next to a large truck, the result could have been a fatal collision. I could have been killed because of this system defect. When a driver cannot be verified, the vehicle should maintain lane control, reduce speed, activate hazard warnings, and perform a controlled safe stop. It should never abruptly withdraw assistance and create a more dangerous condition. I request that NHTSA investigate why a previously reported life-threatening defect remains unresolved and require Hyundai to correct this system logic before someone is seriously injured or killed.

FORWARD COLLISION AVOIDANCE: WARNINGS

I am reporting severe safety risks and inspection fraud on my AWD 2020 Hyundai Santa Fe (VIN: [XXX]) caused by Universal Hyundai in Orlando. Inspection Fraud: The dealer falsified safety metrics, marking my brakes as a failing 4mm to push a $659.90 repair (RO# XXX), then passed those exact brakes at 5mm eleven days later (RO# XXX). Tire Malpractice: Mechanics over-inflated my tires to a dangerous 39 PSI and botched the alignment. This caused structural tire belt separation and severe sidewall bulges. The rear tire has suffered rapid, catastrophic deflation, dropping flat to 14.5 PSI and down to an empty 5.5 PSI. Crash & Drivetrain Risk: Operating an All-Wheel Drive (AWD) vehicle with a rapidly collapsing tire and asymmetric alignment forces the wheels to spin at mismatched speeds, creating severe friction that is destroying the internal powertrain transfer case and causing an immediate highway blowout crash risk. The service manager admitted "human error" and issued a full refund but banned my vehicle to avoid an audit. Hyundai Corporate has been notified under Case #XXX but has delayed resolution. Active consumer fraud file logged with the State of Florida under Case XXX. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2017 Hyundai Santa Fe. The contact stated that while driving approximately 15 MPH on the interstate, the contact heard an abnormal tumbling sound coming from underneath the vehicle. The contact noticed an unknown object had detached from the vehicle. Upon inspection, the contact determined that the detached component was the radar sensor. The Automatic Emergency Braking (AEB) system and the adaptive cruise control became inoperative. The contact stated that the vehicle had not been involved in a crash prior to the failure. The vehicle was taken to an independent mechanic for inspection. The mechanic advised that the radar sensor could not be reattached and stated the failure was possibly caused by a crash. The local dealer was contacted, but the vehicle was neither diagnosed nor repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 130,000.

FORWARD COLLISION AVOIDANCE: WARNINGS

I have had the vehicle in 4 times for check forward attendition warning system light keeps coming on. The first time they replaced the front camera. The situation came back after I was using the cruise control on a express way. Did not do it do it on the road but as soon as you stopped and turned the vehicle off the vehicle check forward attention warning system would come on and off and the only way to shut it off was to stop from more than 20 minutes and it would reset. Took the vehicle back 3 times and they could replicate so there was nothing they could do. The issue came back today. The check forward attention warning system light keeps going on and off. We stopped and let the vehicle sit and upon restarting the check forward attention did not reset . This time the vehicle lost all volume from the dash board. You could recieve phone but no volume. No radio volume. All the safety features that Bing are not working. Check the set up and the volume had a red 🔺️ next to the volume. 4 times into the shop for the same issur

LANE DEPARTURE: BLIND SPOT DETECTION

First Failure occurred 7 months after purchase at 5,270 miles on August 1, 2024. The vehicle suddenly went into "Limp Mode" abruptly decelerating to 25 mph with a non-responsive gas pedal. A code reader displayed PO653 Sensor Reference: "Voltage B Circuit High". Dealer found corroded wire to battery and cleaned it. Second Failure: Horn loss to 1 tone. Fixed at 30K mile dealer service on June 12, 2026 and found to have faulty packing resulting in corrosion. At the same standard service the Brake System was flushed. 3rd Failure was 5 days and 437 miles (30,712 miles) after the 30K dealer service. On June 17, 2026 during my early morning commute while merging onto the interstate, alarms began to blare and the gas pedal suddenly became unresponsive. The initial alarms read Blind Spot Failure. Car would not accelerate from 40 mph that it was going coming down the bridge ramp so I took the very close off ramp down from the aqua duct and the console display alert showed "Engine Management System: details: Braking and Body Control System with a recommendation to get "a full system check...TODAY". I brought it to the dealer that afternoon and as of yesterday, 6/26/26 they can find nothing wrong, declaring it an intermittent issue and asked me to come get the car, refusing to continue looking or providing alternate options other than referring me to Hyundai Consumer Affairs.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

-On [XXX] I was drivng on a highway while using cruise control. The car suddenly applied the brakes hard. I tried 4 times to use the accelrator and each time the brakes were applied hard again. -The car behind me laid on its horn and managed to shift to another lane thereby avoiding a rear end collison. -Fortunately I was driving in an outside lane and got the car to the shoulder. -I turned the engine off and then started the car again. -There were no warning lamps or messages that I can recall. It happened quickly. -This incident came very close to causing at least vehicle damage and possibly physical harm to the occupants of my car and the car behind me. -I took my car to the dealership which is Crown Hyndai in St. Petersburg, Florida. They were unable to recreate the problem so the issue is still outstanding. -To prevent future incidents I no longer use cruise control and turn off the FCA system when I start the car.

FORWARD COLLISION AVOIDANCE: WARNINGS

I have videos of these two incidents and others that I could not upload. While driving on the PA Turnpike at 4:25PM on 5/22/26 75 mph my accelerator pedal stopped responding, my front collision warning light, engine, EPB, and numerous other lights came on across my dashboard despite there being no contact with any object and my speed rapidly dropped. The front camera came on as if there was an object too close. I was in the middle lane. While I was trying to move to the shoulder there were tractor trailers behind me and to my right that began flashing their lights because my speed drastically dropped and was unable to safely stay with the flow of traffic in the heavy rain. While still in Drive car started changing through notices on my digital screen "Check Blind-Spot Safety system" "Check Forward Safety system" with the car crash icon, and "Check Driver Attention Warning (DAW) system." Then I began trying to press the accelerator pedal again and the car would not move at all but the tachometer was going to 2x1000rpm. When I turned the car off and turned it back on again the engine light was still on, but the accelerator pedal was responsive. About an hour later when the tow truck driver from AAA attempted to drive the car on to the flat bed the accelerator pedal was unresponsive again. This was at least the fifth time my vehicle had lost propulsion without warning. Every prior time Bowser Hyundai had different reasons for the failure, made a repair, and said it was safe to drive. Another incident occurred 4/7/2026 using cruise control at 84 mph when the car unexpectedly lost propulsion. The accelerator was again unresponsive, I was on the turnpike with two children in the vehicle. I steered towards the shoulder and the car slowed to a stop. After that incident, Bowser Hyundai replaced the transmission on the car. They notified me on June 18 that they believe they fixed the problem again but I don't feel the vehicle is safe for my family and worry it will be deadly

LANE DEPARTURE: ASSIST

Vehicle experiences severe, intermittent, un-commanded steering inputs from the Lane Keeping Assist (LKA) system at highway speeds (55-70 MPH). The steering wheel violently jerks toward adjacent traffic lanes/shoulders without operator input, lane drift, or warning, requiring immediate high-force manual intervention to overpower mechanical torque and prevent a collision or roadway departure. Chronology of manufacturer notice: - Oct 2024: Initial consumer dispute logs flagged steering safety concerns and unresolved campaign items. - Dec 2024: Opened Corporate Case 24164934, formally alerting consumer affairs to dangerous steering wheel jerking. - Jan 2025: Presented to an authorized dealer; an OTA software update was deployed, but intermittent tracking failures persisted, including failure to recognize lanes at night. - June 2026: Under Case 42680760, the system failed acutely on the interstate, jerking the vehicle out of painted lanes. The malfunction originates in the LKA steering control module and camera hardware, which are intact and available for inspection. Dealerships have not replicated the defect during brief diagnostic windows due to its intermittent nature. The manufacturer has deflected these notifications and refused a forensic diagnostic sweep or mechanical remediation. Instead, case managers attempted to close the file by offering partial financial goodwill for an unrelated cosmetic paint delamination defect on the same vehicle. No warning lamps or error messages precede these events; the system executes aggressive mechanical intervention with zero notice. This system error bypasses driver override thresholds, conflicting with vehicle crash avoidance frameworks. Because the computer fails to log diagnostic trouble codes (DTCs) during these steering drops, the manufacturer exploits this data vacuum to deny structural remediation, creating severe multi-vehicle side-impact and rollover risks.
