No updates to this thread in a while, nobody else having this issue any longer? Has it been root-caused by GM to a specific known failure, or are the dealerships still playing "whack-a-mole" replacing random parts to see if it "goes away"? I too am having this issue on my 2021 Trail Boss 6.2.

I had the same issue. Then it went to loss of power. Seems it only does this when pulling and using exhaust break. Iv added the banks monster Pedel and derringer. And I love the new addition! When I get these errors I can clear right from derringer gauge. And I’m rolling in seconds

Dealer found code c060b left rear parking brake actuator fault. After checking wiring, they determined issue was the actuator. Replaced. So far so good for the service parking brake.

Hi, did this fix the issue for you after the actuator was replaced? Did the "service parking brake" light ever come back on?
