[Chrysler] Loose Gas Cap Warning
If a strange symbol appears on your dashboard that appears to show a car with a chunk taken out of with a screw hovering next to it then your gas cap may be loose.
If you have checked your gas cap and it is correctly fastened then you may need to seek help from a trained mechanic who can check for other problems.
A loose gas cap or a leak in that system can cause pressure issues on modern engines (especially diesel powered one) which can cause the engine to act erratically.
