GM recalled 1 million Chevrolet, GMC, and Cadillac trucks and SUVs to repair an electric power steering module that can fail and increase the risk of a crash.
The recall involves vehicles from the 2015 model year, including:
- Chevrolet Silverado pickup trucks manufactured between April 14, 2014 and October 10, 2015
- GMC Yukon SUVs manufactured between September 19, 2013 and July 17, 2015
- GMC Sierra pickup trucks manufactured between April 22, 2014 and October 10, 2015
- Cadillac Escalade SUVs manufactured between December 3, 2013 and July 23, 2015
- Chevrolet Suburban SUVs manufactured between October 16, 2013 and July 17, 2015
- Chevrolet Tahoe SUVs manufactured between September 19, 2013 and July 23, 2015
GM started looking into the issue in June after it saw an increase of reports that the electric power steering, or EPS, unit in some of its trucks and SUVs experienced electrical issues and temporarily failed. The problem occurred mostly during low-speed maneuvers such as turning.
The loss and sudden return of EPS assist can make it difficult for some drivers to maintain steering control of the vehicle. The problem also could trigger dashboard alerts, notifying the driver of an EPS problem. Other electrical issues may present themselves at the same time, including the shutdown of the radio a loss of air conditioning and cruise control failure.
Dealers will reflash the EPS module software at no charge to owners. That will stabilize the EPS module’s energy usage and allow the voltage to remain at a level high enough to maintain continuous EPS operation.
This recall is similar to one last year that affected almost 800,000 2014 model year vehicles.
GM began notifying dealers on September 7, 2018, and customers can begin scheduling repairs immediately.
