I will take this to the dealership when I get back home. Today, disconnected the batt again. Cleared the codes. And it drives just fine like it always does. But I know it will eventually come back. Such a pain. Truck had a new eng installed at 65k. New transmission at 73k. Fuel pump at 89k. And a throttle body just last week. Can anyone say Lemon??? Last Chevy I will buy!!

Hey guys. Having hell with the 2018 Silverado. Truck has been in and out of the shop for months and it seems they just keep throwing parts at it. I work 9 hours from home and pretty much in the middle of nowhere. So this is getting very frustrating and a tad scary with this issue happening. You can be cruising at highway speeds for 3-4 hours when the truck will start stalling on and off. Its very violent feeling when it does. If you hurry and get off of the gas, it will resume down the highway usually. But lately when the problems start, they will not go away. First time it started doing it. It was happening at about 70mph. Had codes read and everything pointed to the fuel pump. On my 9 hour drive back home. The issues started happening. But then the trans started slipping as well. Eventually tranny went out about 3 hours from home. Had it replaced. Figured that was the issue and the codes were just junk. Well the next month on my way back home. Issue started happening again. Once again the truck broke down about 3 hours from home. Same exact spot actually LoL. And no I don't take that route home anymore. Well the fuel pump quit working. Had it replaced. Next trip down to work. CEL came back on again with P2635 "Low fuel performance" and P2101 "Throttle actuator position performance". Well eventually got it back home. Dealership replaced throttle body. Figured it was fixed until today. Drove 9 hours to work and during the last 30 mins. The violent stalling came back again. And also while sitting in traffic. It would idle rough and then die. Takes about 5 attempts to start before it starts. Runs fine for about 4-5 mins and will do the same thing again. Can someone please tell me what is going on with this turd??? Im tired of getting towed back home.

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.

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?
