“MY FUEL GAUGE METER DOESN'T WORK. WHEN EVER I START THE CAR, THE FUEL METER DROPS TO EMPTY. ALSO, ONE DAY IN SUMMER OF 2011, MY DRIVER-SIDE POWER MODULE JUST STOPPED WORKING. THE POWER WINDOWS AND LOCKS NO LONGER WORK FROM MY DRIVER-SIDE DOOR. I AM CONCERNED I WILL RUN OUT OF GAS ON THE INTERSTATE OR HIGHWAY AND CAUSE A WRECK. I ALSO CAN NOT SEE IN THE MORNINGS FROM MY WINDOW BECAUSE IT GETS FOGGY AND THERE IS NO WAY TO ROLL MY WINDOW DOWN. THIS IS A SERIOUS SAFETY HAZARD. *JS”
