Adaptive Cruise Control problems of the 2013 Subaru Outback

What component or system failed or malfunctioned, and is it available for inspection upon request? actuator assy-epb, part number 26002aj02c (from technical service bulletin), part is not available how was your safety or the safety of others put at risk? brake light and isight warning light comes on. Safety systems will not operate properly when these lights are on has the problem been reproduced or confirmed by a dealer or independent service center? yes has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? no were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? brake light and isight warning light comes on, this started several months ago after driving this car for about an hour, shutting it off then starting it back up after short amount of time, like 20 minutes, the brake warning light and isight light (safety system/adaptive cruise control/automatic braking) will come on immediately, they will stay on until the car has been allowed to cool down for several hours. This happens more often in hot weather. This has happened about a couple dozen times already. Took the car to eurasian autoworks in tilton nh, the mechanic, who I'm told is a former Subaru master tech says this is a common problem and is usually fixed by replacing the emergency brake actuator under technical service bulletin 06-58-17r. I called the local dealership and they do not have any of these parts available. I called Subaru customer support, case number 230720-1600595. And was told the part is discontinued and essentially said I should get one from a junkyard. I do not believe a 10 year old car should have safety related parts unavailable, especially on a common issue with this year/model of car.
