What 194 owners told NHTSA about the 2020 Hyundai Santa Fe Phev

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.

Just read possible recalls on Hyundai Santa Fe's 2025 and 2026's. Just spent $1727.68 at the Hyundai dealership in Gilbert, AZ to replace the front camera do to the faults showing up on the dash. By reading that article it made aware of what may have occurred had we not taken it in for service. This vehicle is a 2020 Sante Fe. You may want to check into it. Oh, I want a refund.

*Problem Parts:I only could check 1 box- should be Brakes and Steering too *ADAS: Lane Keeping Assistance too Over the course of two days, my 2020 Hyundai Santa Fe experienced a serious electrical and safety system failure. It started with the blind spot monitoring lights flickering in the side mirrors and warnings for Forward Collision Avoidance (disabled), ABS, Electronic Stability Control, Downhill Brake Control, Parking Brake & Brake Fluid (blinking red). The rearview camera failed and the screen remained on the radio display when in reverse. The Lane Keeping Assist Indicator shifted from white/green to orange. The next morning, I had trouble opening the vehicle with the key fob. Auto Hold, Master Warning, Forward Collision, ESC, and Downhill Brake Control lights were now steadily on. The MPH numbers on the dash were blurred, and a message appeared saying “Put in P” even though the vehicle was already parked. The accessories light came on, but the engine would not start. Interior lights continued to work. I had to manually open the car and start it by pressing the fob to the button. While trying to exit a parking garage (where a tow truck couldn’t reach me), more warnings appeared: AWD, Low Tire Pressure, Malfunction Indicator (not engine), and Power Steering. I felt tightness in the wheel and had to pull over. The temp and gas gauges dropped to zero along with the RPMs. I have a newer car battery and recently replaced fob batteries, so this was not a simple battery failure. I’ve reported the issue to Hyundai Consumer Affairs. No recall appears under my VIN, despite similar failures being widely reported in this model. I’m a single parent who typically drives with two young children, including one with serious medical needs. I rely heavily on this vehicle for medical travel. The vehicle has since been towed to a Hyundai dealership for diagnostics. This is a serious safety concern and could have led to a loss of control or failure in an emergency situation

Back up camera glitches. Causes driver assist to take control at times when not necessary. Have has this in for service at least 4 times since purchasing vehicle in 2020. Service states repaired each time bit eventually happens again. This last time is getting more severe cause multiple electrical short in Overhead lights, Panoramic roof failure to close at times and rear hatch sometimes only partially opens. I saw recent recall for 2021 and 2022 Santa fe's, I believe this problem is what is happening with my 2020 Santa fe and the scope of the recall should be expanded.

HYUNDAI 2020 SANTA FE LIMITED BLIND SPOT COLLISION-AVOIDANCE ASSIST (BCA) SYSTEM WHEN SET IN ACTIVE MODE AND UNDER THESE CONDITIONS ITS ACTIVATION IS EXTREMELY DANGEROUS: IN THREE (3) OR MORE LANES OF TRAFFIC. IN NEITHER OF THE OUTER LANES. PASSING A TRUCK IN THE LANE ON THE IMMEDIATE RIGHT. VEHICLE(S) IN THE LANE ON THE IMMEDIATE LEFT. VEHICLE(S) IN THE LANE ON THE IMMEDIATE RIGHT. AT SPEEDS OF 50 ' 70+ MPH. WHEN THE SANTA FE APPROACHES THE FRONT END OF THE TRUCK, THE BOW WAVE OF AIR FROM THE TRUCK PUSHES THE SANTA FE TOWARDS THE LEFT LANE LINE ACTIVATING THE BCA, WHICH VIOLENTLY JERKS THE SANTA FE TO THE RIGHT. WHEN THIS OCCURS AND THE SANTA FE IS MOVED VIOLENTLY TOWARD THE RIGHT LINE LANE, THE BSA DETECTS THE TRUCK (OR OTHER VEHICLES) IN THE RIGHT HAND LANE, AND VIOLENTLY JERKS THE SANTA FE TOWARD THE LEFT HAND LANE. UPON DOING SO THE SANTA FE BSA AGAIN DETECTS VEHICLES IN THE LEFT HAND LANE AND AGAIN IMMEDIATELY JERKS THE SANTA FE TOWARD THE RIGHT HAND LANE. THIS ACTION CONTINUALLY OCCURS UNTIL THE DRIVER FORCIBLY REGAINS CONTROL OF THE STEERING WHEEL, AND/OR DEPRESSES THE BRAKE. THIS REPEATED VIOLENT JERKING THE SANTA FE BACK AND FORTH ACROSS THE LANE IT'S IN HAS VERY NEARLY CAUSED AN ACCIDENT IN AT LEAST TWO (2) OCCASIONS (OCT 27 & 28, 2020) UNTIL WE FOUND THAT THE BCA COULD BE DEACTIVATED AND SET TO WARNING ONLY. THIS VIOLENT ACTION OF THE BCA SHOULD BE REMOVED FROM THE SANTA FE VEHICLE TO PREVENT ACCIDENTS.
