Complaint Summary

ELECTRICAL SYSTEM

Owner Narrative

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.
