07 Civic Hybrid Autostop Issue at 7 Bar Charge
 

I am finding that as I have worked harder on my hypermiling in my 2007 Civic Hybrid, I am staying consistently at about 7 bars of battery charge. I haven't noticed a recal in over a week. However, I also notice that at Auto 70 degree A/C on, and running with the engine warmed up fully, the Autostop feature is cutting off after I've sat at a red light for a short period of time, and often may not come on at all. This is strange to me, since I know that with the battery only having 3 or 4 bars of charge, I was getting consistent Autostops at every stop I made. What else could cause the Autostop to restart the engine after only a few seconds at a red light? Is the battery not getting proper cooling? Wouldn't cooling issues cause the IMA light to come on? I really don't want to complain about the 7 bars of charge, since I often get much better MPG with the charge that good.

The only time I've experienced that is when the engine has cooled down enough for Auto Stop to disengage. This is between 150F to 160F. If you have a SGII you can see the temp drop whenever it's in auto stop or in a Glide.
