dealership didn't replace anything last year when this happened, said no codes were coming from the computer and they couldn't replicate the problem. i haven't used the truck much for work since last time it happened because of the coughening. last week was the first week back on a jobsite and the wheels lock up again on friday afternoon. the car was turned off for ~15 minutes and parked in the sun when it happened. same exact symptoms; wheels locked up over 5mph. no engine light. i pulled it into some shade and let it sit for ~1 hr. when i started it back up it let me drive. i video'd it this time, didn't think i would have to the first time https://www.youtube.com/watch?v=-oSvh4zzFXw funny thing is, i'm still glad it's not my brother's 2017 1500

small update while I wait for appointment with dealer: had my buddy check what code it was throwing out. P1005 - powertrain control module this still doesn't make sense, why would it gimp my truck. really wish gm cared about their customers.

Idling for a few hours at work before my wheels locked up as I pulled into live traffic. I work construction on bridges in NYC. I am lucky that my current project is on a side road, else I would be writing this from the bottom of a river. Now waiting to see if the problem magically fixes itself (like others have stated) while I wait for the service appointment. It feels like the electronic parking brake. But I have no 'service engine' light, so is the computer not throwing out service signals? I will NEVER feel safe using this truck for work again. My complaint to NHSTA: -------------------------------------------------------------------------------------------------------------------------------------- Your Vehicle's Make Model and Model Year: CHEVROLET SILVERADO 1500 2019 What part of your car was affected? Brakes, Wheels, Unknown or Other What happened? Pulled out of a construction site after a work day and the wheels on my truck locked up right in the middle of the road. If I was pulling into a highway, I would not be writing this right now. The truck was idling for about 2 hours before I pulled out into traffic. The way the wheels stopped, it felt like the parking brake is engaging when I drive. Maybe this is some kind of limp mode to prevent damage. If that is the case, it is a very dangerous fail-safe to implement on a vehicle that people depend on for work. I do not think it is a coincidence that this is the first silverado model with an electronic parking brake. Oh yah, and this just COINCIDENTALLY happened 1000 miles after my bumper-to-bumper warranty expired. Also, GM customer service is just a call center in India. Don't bother calling them. When did this happen? 08/29/2020
