I just purchased a 2020 Silverado 3 weeks ago. It only had 500 miles when this started happening. It happened about 10-15 times over the course of 5 days. It will come on, stay on for about 3 seconds, then go away. I called the dealership and brought it in but they said there were no codes and they couldn't replicate the issue. The very same night it happened again twice. I dont really know what to do. I took a photo and showed the dealership but on the service receipt they said its "working as intended'. Im very upset I am having this issue so early into owning this vehicle.
