Two problems related to wiper have been reported for the 2011 Toyota Prius. The most recently reported issues are listed below.
The headlights keep burning out, I have replaced the drivers side 3 times in 12 months and the passenger side twice. I only use sylvania brand, but have switched to different brightness to see if it has any impact, it has a slight impact but not much. The headlights are not on when not needed.
Both headlights suddenly went out at night during a rain storm on interstate 10. When this happened. Definitely a safety issue!!.
