Consumer Description

Vehicle's turn signal is not hardware based, but instead relies on the software registering signal use. The turn signal can be "fully" pressed, and "partially" pressed, and the behavior is supposed to be: Full press: Blinks until you manually disengage 1/2 press: Blinks 3 times, then automatically disengages. Anything "between" a full press and a half-press, ie beyond the level which is supposed to trigger a 3-time blink, but not "bottoming out" the signal, regularly fails to trigger the signal at all. This leads to scenarios in which the driver "thinks" they have signaled, and creates unsafe situations for surrounding vehicles.
