The technician told me the power steering fluid looked dirty and needed to be changed. Should power steering fluid be changed at that mileage — or any mileage?

Q. I plan to change the power steering fluid in my 2005 Toyota Highlander, which, in 2005, called for Dextron II. Are Dextron III, IV, and Dextron/Mercron are all okay and interchangeable?

Nissan is recalling more than 56,000 cars because of power-steering hoses that may leak fluid and potentially lead to fires. Nissan North America said the recall affects the 2013-2014 Murano vehicles.
