The front brake hose fittings at the caliper are said to be prone to corrosion, eventually allowing the brake fluid to leak. Braking performance can consequently diminish, extending stopping distances and increasing the risk of a crash.
The problem was first noted in a customer complaint, resulting in an investigation that started in February. The inquiry found that the 2004-2007 CTS-V uses the same brake hoses as the 2003-2007 CTS, which was recalled in 2009 for the same problem.
The campaign is being handled on a regional basis, limited to nearly two dozen “rust belt” states with high road-salt exposure.
General Motors earlier this year succeeded in resisting a push for wide-ranging recalls of older models due to corroded brake lines. The National Highway Traffic Safety Administration agreed that owners are responsible for inspecting and replacing rusted lines, however the latest recall suggests GM views the corroded fittings as a defect rather than a maintenance item.
