I don't drive off road.
parking at an angle light was on. Would that be enough to discharge it? If not, is there anything else that could be draining the power. I think the battery is OK? It's been fine for years.
I don't plan to ever use the heater, do I have to replace that 3 way valve? What are the risks of damaging my electric or gas engine of my Prius?
2005 Toyota Prius Recalls
The affected vehicles have a steering intermediate extension shaft manufactured with metal splines that may have an insufficient hardness. Over time, the splines may wear and eventually fail resulting in a loss of steering ability, increasing the risk of a vehicle crash. Toyota dealers will inspect the extension shaft and replace if necessary.
During manufacturing, a scratch may have occurred inside of the electrically driven water (coolant) pump at the coil wire, resulting in corrosion. The corroded wire may break and the water pump could stop. The corroded coil wire could cause a short circuit in the pump resulting in a blown fuse, creating a stall-like condition of the hybrid system while the vehicle is being driven. This may increase the risk of a vehicle crash. Dealers will replace the electric water pump to correct this concern.
Southeast Toyota is recalling 2005–2011 models for failing to comply with federal safety standards on tire selection and rims. Affected models were sold without the proper load-carrying capacity modification labels, which may cause the driver to overload the vehicle, increasing the chance of a crash. Dealers will mail the correct labels to the customer or install the label free of charge.

I love this car, it has been a joy driving it. The only problems I had was the gasoline gauge was not reading correctly and the rear left tail light burned out within 3 years. Minor annoyance are the Navigator is not worth getting, it takes you aroundabout way and the radio needs better reception.
