I keep getting battery saver activated. I go to start my truck and it will not start. On dash says battery saver activated. I have had in the dealer 4 times and it keep happening. I also have had the power steering go out while driving. This has only happened once and after a couple hours it started working again but seems very dangerous.

Silverado 1500 6-cyl Diesel

  • miles
Vehicle exhibited sudden loss of power at highway speed while in West Texas. Without warning, the vehicle displayed an "engine power reduced" message and the vehicle immediately slowed from highway speed to a maximum speed of 25mph. This sudden reduction in power required the drive to take emergency action to leave lanes of travel for the shoulder. On a road with insufficient shoulder-area, this could have resulted in a collision. Prior to the loss of power, a check engine light illuminated followed by a "Service Emissions System Soon" warning on the driver information display. The elapsed time between the messages and the loss of power was less than 5 minutes. The vehicle did not exhibit any erratic behavior at the time of the warning lights or prior to the loss of power. The vehicle is currently at Bill Estes Ford in Indianapolis, IN. Diagnosis is underway. Indications are that this is related to issues with the emissions control system. The vehicle was up to date on all service at the time of the incident.

Truck mileage approx 26000 miles. 2 wiring harness locations rubbed wires enough to cause wire to wire contact resulting in 1 location, burnt wires, according to service tech and the other resulted in truck malfunction. Threw numerous codes, transmission repeatedly went P, D, P, D....unable to put in park for sometime and then finally was able to. Additionally, when serviced out of state, was recommended to have service done for leaky oil pan. Upon returning to home state, truck went in for oil leak, was returned due to parts ordered because it's leaking at the rear main seal and not the oil pan. Waiting on this service to occur.

As I was backing out of a parking spot in a lot my vehicle lost it's power steering. I got an Service ESC error code, a wrench indicator, and a service power steering/drive with care warning. I also got a diagnostic alert from On Star. Diagnostic Alert: Service Antilock Breaking System in your 2020 Silveragod pithing the next 7 days. I was unable to move steering wheel, and could only pull my vehicle forward. So it was stuck sideways in the parking lot for about 20 minutes. My car did restart again and the code cleared. I was able to drive it to the dealer. They ran diagnostics but were unable to duplicate the concern. They did find a history of 1 fault where several modules (ECM, EBCM, TCM, TCCM) had lost communication with the power steering control module. They also looked at Data Com schematic doc 5257308 and found modules before connector X182 had lost communication. My safety was a risk in this situation because I was stuck sideways in a parking lot with very limited ability to move my vehicle for incoming or outgoing traffic. Had this happened while I was driving the vehicle in a roadway I believe it could have caused an accident. The dealership did find that a harness was making contact with the upper control arm bolt. They re-taped the harness and secured it away from the control arm bolt and bracket. A new bracket was ordered.

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.

I started my truck up and the dashboard warned me with service ESC and also Service Power Steering drive with care. Steering wheel was very hard to turn obviously no matter what way. I only got like 14,169 miles on the truck. I left it sitting for about 2 hrs. And it's supposedly back to normal. No lights some how.

- My back up camera developed a fish eye distortion. - It makes it hard to see how close something is behind you, making it dangerous backing up with children in the area. - Yes, although the dealer is trying to claim it is ''normal'', even though it was not that way when I bought the truck, or I would not have purchased it. - There were no warning lamps or other symptoms prior to the problem. It appeared before 2,500 miles were on my vehicle.

I was leaving work on May 17th and got in my 2020 Silverado and started the vehicle. Immediately codes were thrown on the dash stating that the power steering was out and that the ESC system needed serviced. The traction control system/ESC light was also illuminated on the dash. I was unable to turn the steering wheel whatsoever. I turned the vehicle off and restarted approximately three times all of which still were displaying the codes listed above. I let the truck sit for approximately 20 minutes and the codes had cleared themselves and the vehicle was functioning as it should. I immediately drove to the dealership and had it serviced. Dealership stated there was a programming issue related to the EBCM, which if I'm not mistaken was a recall already issued for the 2019 models. I have seen many instances online of this same issue occurring and sometimes impacting the ability to brake (if vehicle was in motion at time of onset). My onset occurred at approximately 14,000 miles while in park. Since the servicing (approximately 1 week) issue has not been replicated, but I am not sure if the problem has been fixed or if the computer is just functioning properly and will glitch again at some point in the future.

Infotainment system randomly shuts down completely(screen turns off along with all audio and connected devices). Also the usb port refuses to connect and/or randomly disconnects items attached to it. This happens while the vehicle is stopped or in motion. It has done it on the highways, freeways, interstates, city streets, country roads, dirt trails, my works private property, everywhere in short. Happens on hot summer days and cold winter nights. Its 100% random. Chevy knows of the issue but has refused to fix for more than a year now.

Silverado 1500

  • 9,000 miles
The engine light has come on 3 times with a truck with only 9000 miles on it I took it to the dealership who gave me a code of P12A6 they told me Chevrolet is aware of this problem but has not come up with solution yet or even wrote a program to reflash the computer. Now I have a paper weight in my driveway and being that I live in a dual town trying to find a dealership that will fix it and provide rental car or truck. This defect can be multiple reasons with the engine harness wires chaffing or torque converter or transmission plus the whole electrical system not cranking over the truck from what I was told last time. Now I'm waiting till 730 to call a dealership see if they have a roll truck to pick it up and get it to a dealership where they can try to fix this problem.

This truck has 2700 miles on it. Got in to drive it home from the store today and the service engine light is on. Says stabilitrak error and antilock brake error. Brake pedal felt strange so I was afraid to drive it after reading similar stories about trucks veering or not braking when the pedal is depressed. Called dealer to schedule service. This truck hasn't even had its first oil change yet and already having electrical problems.

Silverado 1500

  • 7,300 miles
This truck doesn't even have 7500 miles on it. It was driven to work this morning without issue and parked for approximately four hours. Upon attempting to start it for lunch hour three messages showed up in the dic: 1) 'service ESC', 2) 'service power steering', and 3) 'park assist off'. in an attempt to evaluate I pulled the truck forward and the available steering reflected an inoperable power steering system. I backed into the spot again and shut the truck down. I started the truck and shut it down four or five more times with the same messages presented (although park assist stopped appearing) and only on the last time did the messages go away and power steering returned.
