I have the same problem with my Alphard hybrid E Four 2007.. some indicators on the dasboard flash red on..VSC on, Engine in the middle on and the worst was the car engine lost its power so the engine had to be shutted down..I had to wait about 15 minutes to half an hour and tried to start engine again.. sometimes if got lucky it can be run over but sometimes need to be waited even longer.. the part of cooling system had already changed once but the problem happened again.. how to manage these problems??? Thanks before.. Really appreciate it..
