Voltage from the brake light switch deactivates the cruise control . Have an assistant press on the brake pedal while you check that the brake lights are working properly. Brake lights that dont come on or dont shut off need to be fixed and go from there. Sorry if this doesnt answer you question but I thought i would give it a try.
If you brake lights stay on and the cruise control doesn't work then I would be looking at the brake light switch at the top of the brake pedal as if there is power passing through it then it cuts out the cruise control. The same as if you put your foot on the brake cuts out the cruise control. The hatch button will be another problem like a fuse or broken cable or failed latch solenoid. As to the rear middle brake light try checking the bulb first.
check cruise control fuse and check the brake lights see if brake light working because the brake light switch will deactivate cruise control when brakes is applied.if brake lights dont work either fuse blowed or switch bad.if all is good have vechicle code scan because cruise control control by PCM and vechicle speed sensor and thottle actuator control motor.
The brake light switch, located on the brake padal assembly, is and input to the cruise control module. When the switch fails keeping the lights on is makes the cruise control module think you are applying the brakes when infact you are not. Chek the switch wiring for damage and if ok replace the switch making sure you adjust it properly.
Try pulling up the brake pedal with your foot,Sometimes your brake doesnt come back all the way,and the brake switch keeps the cruise from working.Also,check the fuse.If those answers dont help,It could be the swith itself is bad.Those can be bought at a parts store.
