One problem related to wiring has been reported for the 2011 Toyota Prius. The most recently reported issues are listed below.
I was pulled over by the police, (while on a village street) because my headlight bulb was burned out. (again!) I have had 4 headlight bulbs replaced on the 2011 Prius and it is only 4 years old! Toyota has a technical service bulletin on the wiring harness, that shorts out the bulbs prematurely, but no recall. Please recall the Prius for the wiring harness, so I can stop getting pulled over by the police! 09\15 thank you!.
