2018 Silverado stalls after hitting bumps

[DustinR18]

I have a 2018 Silverado LTZ with a leveling kit on it. Well I hit a good sized pothole the other day and ever since then. Anytime I hit a decent sized bump, the truck stalls and I will get warning “stabilitrack, or reduced power mode, or service 4x4”. I work in West Texas so there aren’t any smooth roads out here. But when it stalls it usually just happens for a few seconds and then everything is back to normal. One time only did it every die on me. But when it did, it wouldn’t let me turn the engine over for 3-4 minutes. Once it was started again, everything was normal. But it did throw a code on that one P0601. Cleared it and it’s never came back. Could this be just a loose ground issues from all the miles this truck has going down bad roads?

Check battery cables and if those are good check the ground in the top of the dash

I’ve checked the battery cables today and all the grounds that go to the frame or block. I haven’t checked under dash yet. I figured it was just something knocked loose by hitting that big pothole. I hit it pretty dang hard.

check the heat shield on the starter to see if has 

come loose

My 2018 Silverado Z71 Crew would stall after a long highway run, in front of my house when backing into driveway. Steering wheel would pull out of my hand, radio would change stations, dash display would change from INFO to radio/audio and sometimes would get the "roll down then up drivers window" message. 

 

Didn't feel like taking dashboard apart, but did check the battery connections. All red/Positive connections were tight as can be, BUT the NEGATIVE BATTERY Connection was so loose, could spin the cable on the post with little effort. After tightening the neg battery clamp, haven't had the issue since (looking for wood to knock on) 

 

Hope everyone else's problem is this simple. Good luck to everyone!
