Ford F-150 2006 4 door . 5.4 L 136548 miles
When I start my truck and either let it sit an run for alittle bit or get in it an go just a few minutes after a unknown buzzer goes off. It beeps four times stop about 5 sec beeps 4 more times stops beeps four more times an stops it does that about 5 time an will quit. Then a hour or so later if I haven't turn the truck off it will do it again but there is no warning light on the dash on or anything. An I just replaced the alternator not long ago

Ours stopped once we filled the tank. But will see if it returns when it gets back down to 1/4 tank.
