I have a 2004 Toyota Camry le equipped with the 2az fe i4. At first I started hearing water sloshing from underneath the dashboard every time I stopped. On 1/30/2014 while stopping for a few minutes in a parking lot the cars temperature gauge started to rise. I immediately shut the car off, and opened up the hood to find coolant had been pushed out the overflow container, then I subsequently brought it to a mechanic. The mechanic stated the head gasket was blown. After a few days the mechanic got back to me, telling me the head bolts had stripped and the engine was unrepairable. I would need to replace the engine. This is a major problem, especially if it gave away when going down the freeway. Toyota needs to step up and fix this issue that is now becoming a very big problem. Toyota did release a TSB for dealers about this but it says to use timeserts or replace the block.
