NHTSA Campaign Id 05V043000; Date: Feb. 8, 2005
If a separation occurred and the hood of the vehicle were open, fragments from the accumulator could cause injury to people in the immediate area. The presence of this crack or fractured surface could allow the hydraulic fluid to leak from the accumulator circuit of the booster assembly. The loss of fluid would cause increased steering and braking effort and a crash may occur without prior warning.
