2020 Chevrolet Silverado 1500 lights problems

Filed Sep 8, 2026 · Electrical, Lights · MD

Body to frame ground cables corroded in half two different times within about 6 months. First time engine wouldn’t start had to have it towed to dealer for repair, over 30 codes were shown when this happened. Next incident some of my lights were working intermittently and my steering was rendered inoperable for 20 to 30 seconds at a time making it impossible to steer the vehicle, several codes were found when this happened, I drove the truck to a Chevrolet dealer for repair. Both repairs were deemed to be corroded ground cables. Chevrolet has a “customer appreciation program” covering 2019-2024 Silverado trucks but for some reason my VIN number doesn’t land in the program even though it has the same issues that are covered for the other silverados.

This is a huge vehicle. Side indicators were required back in 1968, and yet this monster truck doesn’t have any definitive side markers. Also, the standard package does not have any turn indicators on its side mirrors. Even compact cars have this safety item.

The infotainment screen brightness is set too high, such that turning the brightness setting down enough for the infotainment screen to not be too bright turns the backlighting on the instrument cluster down to where it's almost unreadable. In this specific case I was trying to use Apple Maps through Carplay for navigation in an unfamiliar rural area, where lighting on the roads is almost inexistent besides in towns. During the day it's not too much of an issue, but any time between dusk and dawn one must make a choice between visibility out the windshield and being able to quickly read anything on the instrument cluster. It is my opinion that this issue is enough of a safety hazard to force GM to make changes, but unfortunately isn't the most egregious "feature" of this screen. That title belongs to what happens when you put the vehicle in reverse at night. It seems whoever designed it thought the view of the backup camera on the infotainment screen is the only thing you should be able to see, since it changes the brightness back to its daytime setting. This makes seeing out of the vehicle in any direction where the screen is even slightly in your view almost impossible. It also means you must wait a second or two for your eyes to adjust if you want to, for example, look at the backup camera on the screen then look out the rear window. In my case, even looking out the rear window into a garage with a light on was difficult after looking at the backup camera view. Add to all of this any kind of vision issues like needing prescription glasses or contacts, and your eyes are constantly trying to adjust between being able to see what your next turn might be and being able to read any signage that may be present. Simply put, it seems GM took the idea of making the vehicle a rolling smart device to be the primary use, even above having the ability to see where you're going safely.

Backup camera only is functional in perfect weather conditions. If it's dark with no light, the camera has resolution similar to a 1950 tube tv. If it's rainy or cloudy, the backup camera is not functional either. There are numerous yellow lines and extremely poor quality picture in many other conditions too. Chevy has not done anything to fix this issue in my truck. The visibility is so bad I hit my trailer hitch on the bumper 7' off of my hitch location. I couldn't see that my trailer was that close to me on the screen

When putting the vehicle in reverse when its dark the back up camera comes on the radio screen. When doing so the brightness of the screen causes the inability for my eyes to adjust timely. This brightness also causes my inability to safely use my side mirrors because of this blinding effect. There is no way to dim nor turn off this feature. This has always done this since delivery and I've been to the dealer multiple times for other software updates and recalls. This still hasn't been addressed and is a major safety concern.
