Consumer Description
After I had brought a my car to the dealer for its oil change and tire rotation, a warning message came from my car saying "Engine Maintenance Required". After checking with my dealer, they said that the coolant bypass valve needed to be replaced. After checking online, it seems that this is a common problem for recent Toyota vehicles.
