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.
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.
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.
