Power steering failure for a 2021 Chevy Silverado

[Carla Campbell]

My 2021 Chevy Silverado Service ESC  & Service Power Steering Drive Lights comes on and  then eventually goes off.  It comes on while driving or just parked.  One the lights comes on the steering wheel usually locks up first, then allows you to turn (but using a lot of muscles).  I almost hd several wrecks because it came on while driving and I could barely turn or steer.  I notices a recall on other Chevy, GMC, and Cadillac for the same year, but not the Silverado.  Anyone else with a Silverado had tis issue.

Pull back the RF fender liner, the back end of it.  Take a look at the ground strap that's bolted there at the body mount.  It's likely super green or broken.  Replace that and see what happens.

SMA did a video on a 2019 that had the same issue, it was the ground strap on the passenger side. 

At the ~29:00 mark he shows the location of the ground strap, after tis video came out i checked mine.
