2017 GMC Sierra electrical failure


Recommended Posts

I just got my truck less than a week ago 2017 GMC Sierra 1500 SLE 47k mi. 
many given moment the truck will lose all electrical power, radio shut down, dash loses power, time resets, the works. If I auto start the it and it happens the fob is in-op, won’t lock unlock… 

it is from Texas but has been in Alaska for five months, fully winterized, trickle charger, block heater, oil pan heater everything. It gets plugged in every night. 
Has no reported recalls corresponding with the VIN. It does every so often have an action required to open and close the driver window. 
I have seen some issues on the forum regarding ground G218 (might be wrong identifier) but the symptoms aren’t quite the same. 
SEND HELP!

thanks

      I am looking for some detailed electrical drawings/schematics for a 1994 Silverado K1500. I have the Hayne's and Chilton's manuals but may need more information about the electrical system. I had a shop do a LS swap in my son's 94. They did a great job installing the 5.3 with the mated transmission. The motor runs great and no issues with the transmission. But there are items that are not working that were working before the swap. The shop didn't give me an upfront estimate for the swap and was billing me an hourly rate so I'm doing the rest of it myself. I have used the search bar here with limited results. I am a new member here and I'm having a hard time navigating this site. Plus, what's up with all these ads that are everywhere? Thanks in advance for your help.

      My brake lights stopped working intermittently. Now they are permanently out. Checked the bulb, good. Checked the wire, good. What could be causing this?

      This is my first post so sorry if I’m all over the place. I’ve had my 2014 Sierra slt for about two years now. I got it with 116k miles and I’m at about 174k right now. Since the day I’ve bought the truck it’s been nothing but issues. You name it, it’s happened. Four separate water leaks (sunroof, gps antenna, third brake light, and cab vents), 2 transfer case control modules, problems with the power steering going out, brakes going out at low speeds. A couple of months ago my transmission went out and it also needed various other repairs totaling over $20k. Now my park assist sensors don’t work, my rear doors don’t open from the inside and also don’t lock from the outside, reverse lights and camera don’t work, and it constantly dings at me to service my trailer brake system (seriously, it chimes at me about every two seconds as I’m going down the road, telling me to service the trailer brakes). I’ve gone through and checked every ground I can find and nothing helps. Today I went through every single fuse and relay in the truck. I found a couple of blown fuses and replaced as needed, but still no change. I’m at a loss for what to do at this point as I’m stuck with the truck after all the money I’ve sunk into it. Does anybody maybe have any solutions to any of these problems? I’m desperate for answers, anything helps.

      I was having electrical issues on my 2005 GMC Sierra 1500, which is at 197,000 miles. The issues were things like pulsing lights (interior and exterior and low voltage fluctuation (14.0v to 11.8v) so I replaced the alternator with a premium 160amp remanufactured one from CarQuest. Now my voltage seems high, sitting at 14.9v-15.2v during idle. The pulsing went away, but now it pulses when I rev the engine. I will leave it at about 1500 RPMs and it will steadily pulse until I release the gas. Is this an issue with the alternator or something else?

      I got a 2017 Silverado 2lt with remote start and recently a peer of mine got his truck stolen. I want to add something to my truck to prevent that but I can’t really afford the viper alarm system at the moment so i want to install a kill switch in the ignition. If someone could share the wiring diagram that would be awesome because I can’t seem to find it and I was curious if there was a way to install the kill switch without losing my remote start.
