The title says it all. I always use Hilltop reserve, living on a hill. Five days ago I charged the car on my Level 2 Siemans Versa Charge, and came out later to find it still charging with four green blinks, and around 260 miles range. I unplugged it, and took a trip uphill the next day to burn up some KWs. I came home and plugged it in, Hilltop still active. I fell asleep and the car kept charging again. I drove a 130 miles round trip from 1000' to 14,000', to sea level, and back, and plugged in the car when I got home. The car was happy to charge past it's usual 213-215 Hilltop reserve charge, and I unplugged it at 217 miles. I'm taking it to Chevy next week to see what's up. I will report what I find out.

Does it charge past the last two bars? Or does it just look like your estimated miles are increasing?
My car routinely shows 260 miles after charging with Hilltop Reserve on. But car is showing 18 of 20 total bars on the battery gauge.
Only once did I catch my car actually overshoot the hilltop and registered 19 bars after a charge. Believe the car was doing a cell balance on a warm day. But the 19th bar was short lived once driving off.

You can't rely on the range guess o' meter to know the charge level of your battery. That number is determined by recent driving behavior, performance and efficiency. You can use the phone app to see the charge percentage or the advanced driver display to see how many green bars on the left are filled. There are 20 bar sections, each stands for 5% of the battery. After a hilltop charge you should see it stop with two bars unfilled. I've had my guess o' meter show anywhere from 150 miles to 280 miles of estimated range after a hilltop charge, depends on the time of year and how my driving is.
My 19 with the target charging option has gone 1 bar over my set stop rate of 85% once. Figure it can happen for some reason or another. Next time it stopped right at 85%. Dunno what it was doing, but wasn't worried.
Hilltop reserve does not stop charging at a specific range, it stops charging at a specific battery capacity. Judge it by how many green bars are lit on the left side of the instrument cluster, not by what the range estimate is. On pre-2019 Bolts there should normally be 18 green bars lit when Hilltop Reserve charging is complete. 20 green bars are lit when the battery is 100% full.
On the '19s, you can select the charge stopping point. It's not a fixed value.
