    I had this problem for over a year. Dealer "fixed" it for two weeks and $700. After being entirely frustrated I put it up on ramps myself and took a look underneath the rear of the car by the gas tank. Sure enough a hose was unplugged, I cleaned the oring in the fitting and snapped it back together. Problem fixed. NO $$$

    OMG, on going gas cap problem and engine light is going on. Way to expensive to pay a company to check the light and make the light go off. Really we need to buy a chip every time at $400. Any cheaper way to get this done??
