This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.

Parked truck for one hour, engine off. Came back and upon startup, received multiple errors that power steering and ESC required dealer attention. Brake pedal would depress to floor. GMC Sierra 1500 elevation trim
Highway driving engine light started flashing, received codes on service ESC and service parking brake. Truck seemed to loose power transmission started shifting very hard, cruse disengaged, lane keep assist stopped working, brakes and steering seemed to act different. When ignition was turned off loud noises from under truck sounded like brakes releasing with loud clunking noise.
I was going about 15 miles per hour when suddenly all these error codes started popping up, first "ESC malfunction" then trailer brake malfunction, stabilitrak, steering assist reduced, brake system fail, lighs just pop up I do feel like the truck looses some power feels more sluggish, I took it to dealership, they recalibrated the break system and stuff, it fixed the issue temporarily, but the lights keep coming back, sometimes I turn the truck on in the morning and lights are gone, then later on I get all the error codes again while driving it. It started 4 days after I purchased the truck and happens daily since.
