I bought my 2007 Toyota RAV4 new with a three-year warranty. It has always been serviced at a Toyota dealer and after its five year 50,000 mile service in December 2012 I was told that there was a problem with the head gasket and that Toyota would replace the engine free of charge. On further enquiry, I was told that Toyota had extended the engine warranty to seven years or 110,000 miles. This is great service and shows another advantage of a main dealer service even after the warranty has expired.
