2007 Toyota RAV4 SUV Limited 4dr SUV (3.5L 6cyl 5A)
Watch out for the VVTi oil line
 Coming soon to a recall near you:  the external VVTi rubber hose of the 3.5L engine fails spraying quarts of oil all throughout the engine compartment.  This is a very common problem in Toyota's 3.5L lineup and potentially affects Avalon, Camry, and Rav4.  Engine seizures are a  possibility.  Toyota has redesigned this rubber hose as a steel hose for 2009 models but hasn't done much of anything for current 2006, 2007, and 2008 owners.  This line broke at 45,000 miles for me.  For other owners, it broke outside of the power train warranty.  Many Rav4s have needed short block replacement due to this defect.
