I'm just wondering if anyone has any gremlins come and go as mine does?

This summer, I towed my camper about 100 miles from home.

Upon returning home, my GPS would not register my new location and seemed to think I was still 100 miles from home.

Then I got an error message saying, "service vehicle phone, see dealer" or something like that.

Then one day, it went away, and the GPS worked fine.

I believe I got the same error message a few times after that, but they all went away after a couple of days.

Then recently, I kept getting left tail light out the message, and sure enough, half of the LEDs in my left taillight were out.

I began looking for a new tail light, and lo and behold, it started working again and has been fine since.

Most recently, my radio would blip and change stations when I hit a bump.

I did this for a week or two, and now it is fine again.

I'm considering that maybe one of my batteries has a bad cell or is a short or something.

They are both about year-old interstates that were replaced at about a year old under warranty because one went bad.

At that time, I had experienced weird shifting that resolved when the batteries were replaced, which has me considering that again.

Does anyone else have similar issues?
