The center multi-function display failing, the fuel gauge giving incorrect readings and stalling or loss of power due to debris in the mass air flow sensor are common problems with the Toyota Prius, states Repair Pal. There are also recalls for issues such as faulty passenger airbags and seat heaters.
The center multi-function display failing is typically due to a poorly soldered internal connection. Shops specializing in this area fix this problem with ease. The incorrect fuel gauge readings easily reverse with a recalibration procedure. The stalling or power loss occurs when debris falls into the mass air flow sensor during the changing or inspecting of the air filter. This is preventable by exercising caution during inspections.
