Lexus NX300 system malfunction preventing vehicle movement on Lexus NX300

Some Lexus NX300 owners report experiencing a system malfunction that prevents the vehicle from moving, often accompanied by a warning message stating "AWD System Malfunction; 2WD Mode Engaged." This issue may be related to battery problems or could arise even when the hybrid battery's air intake vents are clean, necessitating inspection by a Lexus dealer. Additionally, some owners have encountered this error after inadvertently starting the car with one coil unplugged following a spark plug replacement. When diagnosing these circuit malfunctions, it is recommended to check critical components such as the throttle position sensor, speed sensor, and fuel pump relay/ECU for any signs of failure. Promptly addressing these issues is essential for maintaining the safety and functionality of the Lexus NX300.
