Affected vehicles include the 2015 and 2016 model year Legacy sedans built from March 10, 2014 to April 16, 2015, Outback crossovers built between February 24, 2014 and April 16, 2015, XV Crosstrek CUVs built from October 16, 2014 to April 15, 2015. Also included are EyeSight-equipped 2016 WRX sedans built after March 23, 2015.
The problem rests with the EyeSight system's pre-collision braking system, or perhaps more accurately, the switch that activates the brake lights. According to the bulletin from the National Highway Traffic Safety Administration, should that switch fail, not only will the brake lights not turn on, the automatic braking system won't work either.
Subaru is in the process of notifying owners, who will need to report to dealers to have the system reprogrammed. Scroll down for the official notification from NHTSA.
