- Filed Sep 28, 2026Failure Aug 5, 2025Westminister, SCAir bags, Electrical system
Truck has airbag service issues since day 1. I’ve taken to the dealership and they can’t find any issues even though the service safety system continues to appear. Ac issues and charging issues as well. I’ve attached documentation.
NHTSA complaint 11767616 - Filed Dec 28, 2025Failure Dec 27, 2025Niotaze, KSAdaptive cruise control, Vehicle speed control
Component/system malfunctioned: Adaptive Cruise Control integrated with Traffic Sign Recognition/Speed Limit Assist (camera-based speed sign detection and automatic speed adjustment). Vehicle available for inspection upon request. While driving ~35 mph in 35 mph zones with Adaptive Cruise Control engaged, the system repeatedly misread speed signs (or GPS data) as much higher (e.g., 75 mph). The vehicle then automatically accelerated aggressively toward the incorrect higher speed without driver accelerator input. Acceleration is sudden and strong due to electric powertrain torque. This problem can be reproduced in multiple locations in low-speed zones. Safety risk: Vehicle sped up dangerously in restricted areas (residential, traffic, pedestrians), risking loss of control or collision before I could brake or disengage system. No crash/injury occurred, but risk was high. Problem not reproduced/confirmed by dealer or service center. Vehicle/component not inspected by manufacturer, police, insurance, or others. No warning lamps/messages/symptoms before acceleration; dashboard briefly showed incorrect higher limit. First occurrence UNKNOWN, but multiple incidents since ownership. Appears to be defect in software, camera recognition, or integration of Traffic Sign Recognition with Adaptive Cruise Control, causing unintended high-speed acceleration in low-speed areas.
