VEHICLE SPEED CONTROL, LANE DEPARTURE: ASSIST, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
While driving at highway speeds (approximately 70 MPH) with the vehicle's Assistive Driving functions engaged, the Driver Monitoring System (DMS) malfunctioned. Despite maintaining constant visual attention on the road ahead, the system issued repeated, erroneous audio warnings claiming driver inattention. I attempted to adjust my head and eye position to satisfy the sensors, but the system failed to register my compliance and continued to cycle through warnings. Consequently, the vehicle initiated an unwarranted "fail-safe" maneuver and suddenly applied the brakes while traveling in the flow of traffic. This uncommanded, rapid deceleration created an immediate and severe risk of a high-speed rear-end collision with following vehicles. The failure appears to be a false-positive defect in the eye-tracking software logic and its integration with the braking system. The vehicle is available for inspection to analyze the system data logs.

ELECTRICAL SYSTEM
My BRAND NEW car is suffering an ICCU issue. I first noticed the screens going completely black while driving. I then noticed that I can’t charge at all on Lvl 1 and Lvl2 chargers (AC), but I went to the dealership and the helped me charge on lvl 3 DC fast charging. This is an incredibly dangerous problem, if this results in my 12V battery dying, I could be stranded while driving.

WHEELS
The right front tire pressure sensor (TPS) indicates low inflation when the tire is inflated properly. The sensor will not reset on its own even when the tire is filled to manufacturer standards. Social media forums discuss this as a reoccurring problem in previous and current models.
