On June 1, 2009 I was driving my 2004 Toyota Rav4 with 121k miles when all of a sudden the temperature gauge went hot, the check engine light & vsc trac light came on. Discovered coolant level was low. Took to dealer next morning who quoted me a "head gasket" repair for $1500 out of pocket because warranty expired. After a month of not driving it (to come up with funds for repair), I returned to dealer on July 1, 2009. Dealer advised after taking it apart that the head gasket was leaking and the bolts were "stripped" and I also needed a new engine block which would run about $6,000+. I had never had any other problems with my vehicle until this incident & completed general maintenance regularly. Dealer called Toyota warranty who agreed to pay for engine block (parts & labor for everything below the head) but that I still had to pay the original quote of $1500 for the head gasket, water pump & s belt. I have found several complaints with same exact problem, obviously since Toyota agreed to pay for part of this they know something is defective but will not make a recall. I feel they owe me the head gasket repair as well since it is all part of the same problem and will file a product complaint with Toyota.
