This morning, I found that my 2012 Volt’s Trip Meter A and Trip Meter B both had reset themselves to zero overnight.

In the nearly six years I’ve driven this car, I’ve never seen that happen.

Makes me wonder if GM does have some over the air software update (dis)abilities they are experimenting with.

Has anyone else seen this happen?:confused:

Check the 12V battery terminal clamps, they do come loose.
Was riding with a coworker. After we where done with a meeting, we got back in their car, they turned on the car and the lights came on for a blink of an eye and then nothing. No sounds, no start. Nada. He had had a new battery installed a few day earlier. Popped the hood and he pressed down on the battery cable cover while I started the car. The car started right up. Yup, the cable was completely lose. It's a wonder he'd had no trouble before then.

FWIW: Lack of 12VDC AGM battery power has never reset either trip odometer(s) on my 2013 Gen1.

Trip A is still sitting with over 70k that has accumulated since leaving the dealership!:cool:

On the other hand, I regularly zero out the Trip B odometer

Once, the car didn't recognize the transmitter. I had to use the key to open the door and the alarm came on, then went off. I had to stick the key in the hole on top of the dash to get the car going. When I got home, the first thing I checked was the terminal clamps. Sure enough, one was loose so I snugged it up and since then, the incident never happened again.

I wouldn't put it past anything happening due to loose terminals or a failing battery.

Fun fact; when my Trip A hit 99999 it just stayed there. Didn't turn back to zero or change at all for a few hundred miles.
I finally reset it.
