Vehicles Affected: Approximately 57,192 model-year 2015 Chevrolet Silverado and 2015 GMC Sierra 2500/3500 Heavy Duties
The Problem: GM is reporting that the power steering hose may not be properly attached to the power steering pump. If the pickup truck is driven with an unattached clamp, the hose may disconnect from the pump, which would cause a rapid loss of power steering fluid and result in loss of power steering assist and Hydro Boost powered brakes without warning. The pickup would revert to manual brakes and steering, increasing the risk of an accident. GM is unaware of any crashes or injuries related to this issue.
The Fix: Dealers will inspect the power steering hose clamps in two locations and ensure they are properly attached for free.
What Owners Should Do: GM has not yet provided an owner notification schedule. Owners can call Chevrolet at 800-222-1020 or GMC at 800-462-8782 for more information.
