The 2012 Toyota Prius comes equipped with a timing chain. Typically, spark plugs should be replaced every 100,000 miles, though if they are copper spark plugs, they should be replaced every 30,000 miles. Your air filter should be replaced every 15,000 to 30,000 miles, and the coolant should be changed every 60,000 miles. While using the car, you may encounter various engine issues such as a loose gasket that needs tightening, a spark plug popping off, which can cause engine problems, or the serious issue of engine overheating that may lead to fires and even an explosion. Excessive oil consumption can occur, necessitating more frequent oil changes, and any oil leaks should be promptly repaired.
