My apologies if this is mentioned elsewhere - I did not see it.

The past few weeks/months the tighten fuel cap messages comes on and will then disappear after a few starts/day.

Today, I got a few more messages as I stopped to park - 77 check AWD system and P145C - check emission system.

I started it a few times and the 77 hasn't come on again but the check emission system is still on.

2011 MDX with tech package. 83,000 miles. Premium fuel only.

Any thoughts/suggestions??

77 in SH-AWD is just a code for an General Error, Usually pops up because of something in the emission system is malfunctioning.. Fix that P145C and the SH-AWD 77 will fix itself.

A couple of years ago, my Honda Element had this exact same symptom. I inspected the gas cap carefully and it looked fine; it still clicked as sharply as ever when closing it. But, seemingly at random, the warnings reappeared. And they were slowly increasing in frequency. Finally, I bought a new gas cap and never saw the problem again.
