My new to me 2014 Express 2500 ,with only 31,253 miles, occasionally beeps 5 times after I start it. Then it will beep once every minute or so a few times then eventually stop. No warning lights are showing on dash and the vehicle is running fantastic.

Any ideas what it could be?

Thanks!

 

do all the warning lights work? Do you see them come on during the power-on lamp test? (cross check with your manual to make sure they're all working).

 

I’ll check them during the lamp test today. Thanks!
