Has anyone else noticed this?
The last two times that I interrupted the regens first at STM 11 and second at STM 19, the regen process did not resume when I restarted the car. The STM gradually built back to 22 with normal driving and then restarted the regen. I think this makes more sense than continuously restarting regeneration every time you take a short trip until it reaches 2. I am just wondering if GM changed the computer program to do this or if this was just an anomaly?

I had the car serviced in November. There was a note on the bill (I don't have it with me) about updating the software. I have had two interrupted regens, and both did not restart until STM 22. I'm curious to see if it keeps doing that.

My thoughts on this are based on my observations of interrupted regens. An interrupted regen will not restart in my car until it it thoroughly up to operating temperature. Many times, it will add several grams back in before it restarts an interrupted regen. Did you drive more than 10 minutes immediately after the interrupted regen? That's now long it takes mine to restart sometimes, especially if it's cold out.

That is not a set amount of grams that it will restart at. I believe I have updated software too, but not 100% sure.
I'm sure I drove far enough to restart the regens. I'll keep watching. It could take some time to know for sure. Thanks.
