On the 1999-2002 Chevrolet Silverado, if you own a 1999-2002 Chevrolet Silverado that has spent its life on salted winter roads, this recall applies to your truck. NHTSA campaign 05V379000 was launched only in the salt-belt states (Connecticut, Delaware, Illinois, Indiana, Iowa, Maryland, Massachusetts, Maine, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin and D.C.) because the defect is far more likely to show up where the environment is corrosive. The failure mode is unwanted antilock brake system activation: the ABS cycles when the driver has not lost traction. The consequence GM and NHTSA describe is increased stopping distance during low-speed brake applications, which could lead to a crash — the kind of situation an owner is most likely to meet pulling up to a stop sign or in traffic. The Silverado is one of several pickups and SUVs in the campaign, which totals 1,353,718 vehicles across all of them combined. Repairs started September 22, 2005.
Common Symptoms
ABS engaging unexpectedly during normal low-speed braking
Truck takes longer to stop in low-speed braking situations
How to Fix
Free of charge at any Chevrolet dealer. The dealer pulls the wheel speed sensor out, cleans the sensor's mounting surface on the wheel bearing thoroughly, treats that cleaned surface with rust inhibitor, greases it, refits the sensor, and finally measures the peak-to-peak output voltage to verify the wheel speed signal falls within spec. Run your VIN through nhtsa.gov/recalls to confirm whether the work was ever performed on your Silverado, or call Chevrolet at 1-800-630-2438.
On the 1999-2007 Chevrolet Silverado, gMT800 Silverados (and the related GM trucks/SUVs) in salt-belt states are widely reported to suffer rusted-through steel brake lines, leading to a sudden brake-fluid leak and loss of pedal/braking. NHTSA investigated ~6 million 1999-2003 GM trucks and SUVs after an owner petition; the agency closed it with no recall, concluding the coated-steel lines corroded at rates similar to peers. NHTSA logged 240 corroded-brake-line complaints for the 2004 Silverado/Sierra and 112 for 2006 alone. GM offered a pre-formed brake-line replacement kit via TSB (13-05-22-001) rather than a recall. Fuel lines on the same trucks rust similarly. Very high real-world demand because it is a safety failure on a hugely common older truck.
Common Symptoms
Soft / sinking brake pedal or pedal goes to floor
Loss of braking / longer stopping distance
Brake-fluid leak on the ground
Low brake fluid warning
Visible rust/scaling or weeping on steel lines
Fuel smell from rusted fuel line
How to Fix
Inspect all steel brake and fuel lines for scaling, pitting and weeping, especially over the rear axle and along the frame. Any line that is rusted, leaking, or that flakes under probing must be replaced — best practice is to replace affected lines (or the full set) with stainless-steel or coated pre-bent lines (GM offered a pre-formed kit). Do not drive a truck with a leaking brake line. Undercoating and washing the underbody after winter driving slows future corrosion.
