What the notice says today
The consequence
If the brake system develops an external leak, it may result in a loss of brake fluid below the detection level of the fluid indicator switch. Without a warning, the driver may be unaware that the brake fluid level is low. A low brake fluid level may reduce the available braking force which could lengthen the required stopping distance and increase the risk of a crash.
The remedy
Bosch will notify customers and replace the fluid level indicator switch free of charge. The recall began on April 4, 2013. Owners may contact the Bosch Technical Support and Warranty Hotline at 1-855-426-7247.
