Toyota issues service campaign for Prius V exhaust system
Part of the hybrid drive system on the 2011 and 2012 Toyota Prius V is the exhaust heat recovery system, which uses engine coolant and a system of valves to help the car heat up more quickly. As the coolant carries heat from the exhaust system to the engine, the proper operating temperature is reached more quickly. This system can also help the heating system to warm the inside of the car more quickly. However, in the 2011 and 2012 Toyota Prius V, there is a chance that the actuator valves that control the flow of the coolant for the exhaust heat recovery system may not be strong enough. Should the control mechanism of the system not function properly, there is a chance that the coolant could leak from the system and in addition to the obvious issue of coolant loss – the Prius V may go into the “safe mode”. Safe mode allows the car to be driven but only at very low speeds, essentially bringing the car to the point of being inoperable with the exception of being able to get it off of the road.
