Rearview System Braking problems of the 2021 Tesla Model Y

- computer appears to stop working in colder temperatures (or random). - all cameras, including rear view camera (needed for backing up) and side cameras stop working. Error message shown on touch screen saying cameras are not available. - all road sensing information including other cars, lanes markers (everything) disappears from touch screen dashboard and no longer works. There are no longer any warnings for anything. - gps tracking stops and no longer tracks along with the car. Car becomes a safety hazard due to poor visibility. Especially evident during reverse.

This report addresses concerns regarding recent safety updates in the Tesla Model Y, specifically focusing on the "rear cross traffic alert" and the blind spot warning system. These updates are intended to enhance driver awareness and prevent collisions. However, there are significant shortcomings in their current implementation that may compromise driver safety. 1. Rear cross traffic alert: intended functionality: the "rear cross traffic alert" is designed to warn drivers of approaching vehicles from the side when reversing, thereby preventing potential collisions. Current implementation: the system currently highlights a portion of the infotainment screen in red when a potential hazard is detected. There is no accompanying audible alert to notify the driver of the danger. Safety concerns: drivers are likely to be looking over their shoulder or at their mirrors while reversing, rather than at the infotainment screen. The lack of an audible alert means that drivers may not notice the visual warning, especially if their attention is directed away from the screen. This could lead to an increased risk of collision, as the visual cue alone may not be sufficient to capture the driver's attention. 2. Blind spot warning system: intended functionality: the blind spot warning system is designed to alert drivers of vehicles in their blind spot when the turn signal is activated, helping to prevent lane-change collisions. Current implementation: similar to the rear cross traffic alert, the system highlights the screen in red when a vehicle is detected in the blind spot. No audible warning is provided to alert the driver. Safety concerns: in adverse weather conditions, such as rain, drivers may rely more heavily on blind spot warnings due to reduced visibility. Drivers typically turn their heads to check for vehicles, which means they may not see the screen's visual alert. Without an audible warning, drivers may inadvertently change lanes into an occupied space, increas.
