Can a software update really break your charging? / Bolt owner after the battery-recall dealer visit, now seeing a lower charge cap or less range

Bolt owner after the battery-recall dealer visit, now seeing a lower charge cap or less range

What people actually reported
Range at 80% fell from ~170 to ~130 after update
“Mine's a 2020 and had the update done about 3 weeks ago. Before that, 80% showed about 170 miles every morning. Starting the day after I picked it up, it's been around 130, and the weather hasn't really changed.”

Recall capped charge at 90%; estimate fell 240 to 216
“On my 2019 the recall software capped it at 90%, not 80. It took the estimate from about 240 down to 216.”

Stops at 80% and TOU schedule wiped after update
“Mine's a EUV and it stops at 80% since the recall update, so maybe it's 80 on the newer ones and 90 on the older ones? The update also wiped my time of use schedule and I had to set it up again.”

Showed 175 miles on first full charge after recall
“Mine got it at the final recall appointment last week, and the first full charge afterwards showed 175 miles with the HVAC off at 60 degrees.”

Showed 199 miles at 100% (max 234) on replaced pack
“Mine's a 2019 and GM's site shows the battery was replaced 4/1/22. I've only charged it to 100% once and it showed 199 miles, max 234, which is well under what I figured a new pack would give.”
