2004 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.
Toyota is recalling 2004–2010 models for an accelerator pedal that can get stuck in the wide open position due to problems with the floor mat. This may cause high vehicle speeds that make it difficult to stop the vehicle, which can result in a crash. In order to correct the problem, dealers will replace the pedals, alter the shape of the floor, and/or replace the floor mats. Toyota will also modify software on certain models to ensure that the brake overrides the accelerator in the event that both are applied.

Surprisingly this car carries tons of s...
I love this car (I have had 2 previous Prius's The only conpaint I have is the body seems to be made from the lightest and cheapest material Toyota could find. By even looking at the car, you seem to get a dent !! Does anyone else have this problem or is it just me? I would recommend this car to anyone that wants a fun and gas sipper for a car.
