You can reset the CIC/NBT via a scan tool like an Autel or Launch. It's the "Code" function within those scan tools, which is more of a factory reset in those tools.
Although your glitches may be associated with a failing battery, check your battery and replace + code if necessary. We see random faults come up with aged batteries, from NBT resetting randomly to blind spot faults.
