Entertainment screen electrical issues

[Tesmond Hurd]

When driving last weekend I noticed my entertainment screen (media and display of HVAC info) blacked out for a second and came back on. This happened 3 or 4 times then didn't happen again, so I didn't think much of it.

 

Today, when arriving home and slowed to 2-3 mph, shifted from drive to reverse, and the rearview camera came on like normal, then I lost power to my dashboard (odometer, fuel gauge, etc), my steering, and the entertainment display screen. It came back on after a second and I was able to back in to my driveway with no issues. I never lost engine power and I never heard any unusual transmission noises.

 

Any ideas? I assume it's electrical in nature, just not sure if it's a fuse, a connection for the screen/dashboard gauges, or just a bad battery ground.

 

I'm driving a 2015 Chevy Silverado 1500 5.3L V8 with 80k miles.

 

Thanks in advance!

Mine has done the same thing a few times recently. The last time this happened, the radio wend crazy. It was changing channels and I could not turn it off or see the display. This is on a 2017 silverado.

My 2016 is doing the same all power is lost as I slowly turn steering wheel truck erratically shuts off and back on. I hope this is a recall due too how dangerous it could be in traffic. GM please notice this issue.

Welcome to the site.

 

Sorry to hear about your truck, but have you had anyone look at it? If it is the major problem you make it out to be, why are you still driving it? 

This site is not owned by GM, so pretty good chance they will not be looking here to start a recall.

 

Call a local dealer, give them your VIN, call GM customer service, open a claim, but complaining here will probably be the least likely way to get your truck fixed.

@JimCost2014 obviously everyone knows you need to take it to a mechanic that can read the vehicle computers, but sometimes it's nice to try and fix things on your own. Mechanics are expensive... especially dealer mechanics.

Completely understand, and your post was very detailed, and asked for help.

 

I one that I replied too was basically very vague, with no real information for anyone to even give a good guess. Most answers to it will be all over the board and probably be no help.

 

Your issue will probably be one of 3 things, your battery is failing, you have a bad ground somewhere, or your HMI module is failing.

Those seem to be the main culprits in the situation you are having.

Don't worry, most of the response on here are; 

 

1. Go to the dealer

2. Go to one of the site sponsors

3. Try 1 or 2 again
