One problem related to fuel injection rail has been reported for the 2007 Toyota Matrix. The most recently reported issues are listed below.
In August 2007, I began to smell gas inside my car when driving my 2003 Toyota Matrix . The fuel pressure regulator had failed, causing the seals on the fuel injectors to fail. My service center replaced the fuel rail and injector seals. My understanding is that other Matrixes have had similar problems, leading me to wonder whether this health and safety problem results from faulty design.
