2018 Chevrolet Silverado 1500: loss of power steering

Filed Sep 10, 2025 · Acceleration, Electrical · TX

Truck was intermittently losing power steering and shutting off/reseting itself. Was a loss of electrical and was throwing Stabilitrak Service warning. Would not stay on due to truck resetting itself but loss of power happened typically when I was in parking lot or driveway. Could have easily been on the highway which could have been deadly. Dealership found that the battery cables and module were not getting enough power to truck. Replaced these and it seems okay now. Total cost was ~$1200. I see several recalls for battery cable issues but nothing pulling on my 2018 Chevrolet Silverado 1500 LTZ crew cab.

The electrical power steering failed on my way home as I turned in to my street my steering became very hard to control nearly causing me to crash into a neighbors vehicle. This is the second time my electrical power steering has failed. About a year ago the original electrical power steering went out and a new one was purchased from a dealer ship and installed by a automotive company. Here we are a year later and it has gone out again but this time almost causing me to crash during a turn into my street. NO WARNING to me at all that my power steering was about to go out. Yes. My 2018 Silverado truck is available if an inspection request is asked of me.

I started my vehicle and put the truck in reverse to back out of a parking spot. Gave the truck gas and it wouldn't accelerate. Put the truck back in park and looked at the guages and there were no RPM's showing on the cluster and the oil pressure was at zero. There was a message that said trailer brake system on the screen. I turned the truck off and on again and the same thing happened. I put the truck in drive and it would move forward but the motor ran very rough and there was no power steering. I dismissed the first message and another message popped up that said "steering assist is reduced, drive with care." I pulled into another parking spot, turned the truck off, and waited for a ride. I started the truck when my ride showed up to make sure it was still not working and it was as if nothing happened before. The truck had no issues on the 16 mile drive home. Got home and turned the truck off and started it again and the message came back up and the issues came back. I have a video of the trailer brake system and me shifting the truck and the guage cluster. I have a picture of the steering assist message.

Loss of power steering assist when first starting the vehicle. A message is displayed on the info panel in the center of the dash and all steering capability is lost. It's impossible to turn the steering wheel when this happens. Both times the vehicle has been stationary and I've been able to correct the problem by disconnecting the battery and then reconnecting it. I've reported this issue to the local chevrolet service center and they told me to continue monitoring the problem. I'm obviously concerned that this will happen when I'm driving, since, like I've already mentioned, you completely lose the ability to turn the steering wheel. Other messages pop as well. "traction control system requires servicing." "trailer brake requires servicing." many of the electrical features on the dash quit working.
