NHTSA complaint #10182540, filed 2007-02, 75,000 miles“On may 4th, 2008, at or around 12:30 pm, I was driving my 2002 Toyota Prius normally. The hybrid system gave me a trouble light prior to leaving an auto parts store parking lot; however, I attributed the warning light to a recently replaced charcoal canister and dismissed the warning light, believing it to be related to the recently replaced part. I left the parking lot and proceeded on to my destination, which was my house, about 2 miles away from the store. Without warning, and safely on a street with little traffic, as I was driving up a slight incline, the engine failed to start. …”
