Electrical Problems??

[SilveradoK86]

So I leave work and I go to start my 2014 Silverado LT and it won’t start. Tried 2 more times and was able to finally get it going but the anti-theft deterrent was enabled and I was not able to get it to clear or put it into drive. Called Onstar who stated that they could call a service center to see if someone could walk me through what to do, but was unable to get anyone with any sense on the phone. One lady suggested it did this before I had my cell phone too close to my FOB and key so the signals were getting mixed up… Anyway, I turned my truck off and restarted it and it was fine. Later when I tried to restart it, it did the same thing and was able to clear it. On my way home, a stabilitrack alert came up and my locks started unlocking and locking themselves while driving. About 5 minutes after this started, my wheel jerked to the left and my truck started to chime so I had to pull over and threw it into park for about 15 min. I was able to make it home but upon my arrival, another stabilitrack error message came up stating it had been disabled and my speed would be reduced and my ABS light came on stating it was also disabled and my truck started to chime like crazy, Ugh! I popped the hood and undid my negative battery cable for about 15-20min and then put it back on and everything seemed fine for the most part. I haven’t driven it anymore since but anyone else having ALL of these issues??? I’m kind of hesitant to drive it and thinking of having Onstar tow it to the dealership for me, just wanted to see what anyone else had to say about these issues. Thanks in advance!

i had this happen to my truck once, it was because the aftermarket remote start wasnt wired correctly

Huh, I don't have any aftermarket electrical products installed on my truck.

Time for a dealer visit. I remember reading where have been some issues with grounds and electrical connectors causing similar issues. Trying to find the thread for you. I do remember that there is a TSB or some procedure GM identified to troubleshoot these types of issues, but they have to be solid (which yours seems to be).

 

Here's one thread...talks about the Range device, but also a ground issue..i'll keep looking for the other one

OK, here's the one where they talk about the troubleshooting process

I had some weird electrical stuff going on a month or so ago, truck was gone 2 days, turned out to be a ground. It has been fine since the repair.

Thanks for your help guys. I put in 3 calls to my dealership this morning. I didn't have any issues driving into work this morning, but why risk it.

When I took mine in, they got more than 20 different codes for stuff. They said they called GM support to get to the bottom of it.

[SilveradoK86]

Ugh, great! They finally called back and no more appointment until Monday. Guess I'll be driving my other Chevy. Thanks for all your guys help! Hopefully they can figure this out....

Well, got my truck back today. Ended up being a bad fuse box, so they replaced the whole thing. They said they had another truck 2014 come through with the same problem earlier last year.

So far I've fixed the two grounds at the base of the pillars but that only lasted for about 2 days. Consequently, I did notice that my battery indicator held a slightly better charge and the issues went away for a few days. However, the gremlin is back. I'll move onto the other issues and keep ya'll up to date.
