This weekend, my 2011 Honda Pilot (12000 mile) started showing “Tighten Fuel cap” sign. I opened the fuel cap & close it again tightly to make sure it is properly closed but the sign did not go away. I tried it couple of times with no success (I even shutdown the engine, restart it). So I was thinking to take it to my dealer after the weekend. But next day, when I start my car again, the sign went away & it did not come again for last 2 days either.
Any idea why it happened? Should I be worried?
Thanks in advance for any advise.
