Subaru Impreza owners have reported 2 problems related to turn signal (under the exterior lighting category).
The rear-end lighting (brake lights, turn signals) for a number of recent model years from a few manufacturers is absolutely terrible. If it hasn't already caused accidents I would be completely amazed. I have seen, on at least Subarus and volkswagens, brake lights and turn signal lights which are virtually impossible to distinguish in real-life driving scenarios. I am an exceptionally skilled and attentive driver so this hasn't caused me any harm yet, but I know most drivers are not skilled or attentive.
