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 Ontario, Quebec,
Newfoundland, New Brunswick, Nova Scotia, and Prince Edward Island. 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 travelling 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.
