What a lemon!
 We have had our 2010 Prius for over a year and aside from the excellent gas mileage, I would not ever recommend this year model.  The 'regenerative' braking system is so unreliable, that driving it over uneven road surfaces, the brakes fail and the car keeps moving.  If there were a pedestrian in the cross walk, they would have been hit.  Recommend you check out similar complaints on the National Highway Transportation Safety web site.  I think the problem is with this year only-it was recalled back in Feb. 2010 but the problem persists. We are trying to get rid of it, but have not found a dealer who would give us a decent trade-in.  Toyota has been hard to deal with in this regard.
