    The check engine light stays on and periodically the indicator warning flashes saying check gas cap. I have replaced the gas cap, but nothing changed.

    Check gas cap warning starting coming on last week. On Sunday the check engine light came on and stayed on. I have tightened, unscrewed and screwed the gas cap. Electrical? Also, has anyone else had problems with the radio? I can turn it on, but there is no sound. If I turn the car off and restart, the radio works again. The display shows the radio/CD player on, but no sound.

    Same issue, engine light is on. It states to "check gas cap." I replaced the gas cap twice and had the dealer to reset the light. Came back on the next day.
