Condition
General Motors has decided that a defect which relates to motor vehicle safety exists in certain 1999-2002 Chevrolet Silverado, 2000-2002 Chevrolet
Tahoe, Suburban, 2002 Chevrolet Avalanche, 1999-2002 GMC Sierra, 2000-2002 GMC Yukon, Yukon XL vehicles located in the areas shown above.
These vehicles may have a condition permitting corrosion to occur between the front hub/bearing assembly and the wheel speed sensor. If the brakes are
applied while the vehicle is traveling at a speed of greater than 6 km/h (3.7 mph) but less than 16 km/h (10 mph) the corrosion may cause an unwanted
anti-lock brake system (ABS) activation. If this condition occurred where stopping distance is limited a crash could occur.
Correction
Dealers are to inspect clean and treat the affected area. In some cases the front wheel speed sensor may require replacement.
