 I have been driving my Camry for 6 years.  Very few issues until i hit 90k miles.  My check engine light was on due to engine issue.  Dealership said no big deal EVAP system not an issue.  I had the whole engine drained and cleaned.  50 miles later, BING, light on.  I took it to an independent service provider and they told me something is not right.  Then at 130k miles, the engine pistons shoot through the casing into the combustion chamber.  That could have easily started an oil fire that would have sparked into the gas chamber.  The mechanic said Toyota has a serious engine design problem.  Google Toyota engine issues, it is not an isolated issue.  Toyota is waiting for another blow.
