Every now and then, I hear a chime and my battery light illuminates along with the BRAKE light warning. A message says to check the charging system. After about two minutes, I hear another chime and the battery light turns off, but the BRAKE light stays on until restart.

Any ideas? 2023 F150 Lariat

TIA

 

sounds like a weak battery. have them check it at the dealership, it may be under warranty. it will probably test good, doesn't mean it isn't bad.

 

It’s a brand new battery. Fully charged with a charger as well.

 

My experience with Ford vehicles is that they are full of electrical gremlins. Of my last four new Ford vehicles, three have experienced electrical issues. Two were intolerable and the vehicles lost their happy homes.

 

That sure is an odd issue OP. Mine is the 360 camera going off. It happened half the time when I first bought the truck. I would get a message that it is not available and to see the dealer. The problem went away over the last few months and yesterday I was hauling some lumber with the tailgate down and when I went to back into my driveway the camera wasn't working. I have to get it to the dealer.

 

if battery and connections are good, they next is loose grounds. start looking for ground connections.

 

any in particular?

 

there are some on the frame going to the body and engine. there is one particular that is exposed. its under the passenger seat and attaches to the frame.

 

has the alternator been checked?

 

It has not. Heck, the truck is not even a year old. The other day I was driving down the road and my entire dash display went dark for a couple of seconds. Weird.
