The agency said that its investigation will involve 430,000 Harley-Davidson motorcycles of model years 2008-2011, with anti-lock braking systems (ABS).
According to the NHTSA, it has received 43 complaints, three reports of crashes and two reports of injuries. Reports indicate that the ABS module corrodes and fails as a result of the brake fluid absorbing moisture, from the surrounding environment, resulting in sudden brake failure without warning.
