What's wrong?
The electric power steering assist on the 2015 Silverado 1500, Sierra 1500, Escalade, Tahoe, Suburban, and Yukon adds motor help to the steering system. At parking-lot speeds and during tight turns, it reduces the effort needed to turn the wheel. The truck or SUV still has manual steering, but the assist is what keeps the wheel from feeling suddenly heavy.
On affected vehicles, high-current events during low-speed turns can pull system voltage too low. If voltage drops below 8.8 volts for more than 1 second, the power steering assist shuts off. It returns after voltage reaches 9 volts for at least 40 milliseconds, so the driver can feel a quick loss of assist followed by a sudden return.
A driver information center message can alert you to an electric power steering problem. Other electrical systems can shut down at the same time or just before it, including the radio, StabiliTrak, chimes, door locks, air conditioning, or cruise control.
