What owners wrote
Tl* the contact owned a 2011 toyota prius. While driving 40 MPH, the vehicle lost power without warning. As a result, the contact crashed into a tree and a cement barrier. The air bag failed to deploy. The vehicle was restarted and was able to be driven to the contact's residence. The contact sustained back, neck, and chest injuries that did not require medical attention. A police report was not filed. The vehicle was not taken to a dealer or independent mechanic for diagnostic testing.
My headlights keep burning out. Toyota is aware of this common problem and it requires a new electrical harness. They issued an extended warranty to fix this, however not everyone got the notice (like me). It expired in nov. 2019. I was quoted $700 to fix this, when it is a known defect in the car manufacturing. I would like this be a recall item, so everyone can get it fixed. When I took my car in to get it fixed they were fully aware of my problem with this make, model, and year.
