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!

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.

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.

Here's the most up-to-date PI that was released by GM. PIT5405B

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.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Average Assembly 4.8%   That's the likelihood of a light duty vehicle reaching 250,000 miles. Link below has the stats on this. Among pickups the 350 series (Dodge)  and higher (450 Ford) are most likely and nothing American built in the lighter trucks pegs a number higher than the overall average.  200K and up is the stomping grounds of Asian vehicles. Toyota Sequoia the leader at 39.1% probability.      https://www.autoweek.com/news/a68886903/vehicles-most-likely-to-last-over-250000-miles/   Likelihood drops dramatically at 100,000 miles of reaching even 150,000 miles. 250,000 is deep in the tail of the curve.    I've been told by the 'experts' that I don't need oils of the caliber I use. My high viscosity is damaging my motors. Ash content it to high and WILL foul plugs and kill cats and O2's. I don't need that much ZDP; my choice is over added and not cutting edge. I change it to often. I baby them to much.    Three Honda's reached 200K + and none used oil. All Red Line motors. All sold to friends or family. One Toyota reached 300K using oil, Pennzoil. Dizzy 300K using QSUD until it cashed the rings at 80K then whatever but often ever since. Did you know this engine still sports the OEM timing chain and is dead silent? Pepper spitting into the wind short of 200K, Red Line and changed often. Uses zero oil. A HPFP and a pinion seal. Still using most parts it left Fort Wayne with. So 50% of my vehicles have gone past 250K and 100% of the last half dozen past 200K. Of these two using "shelf oils' did so using abnormal oil and the four that used a premium boutique oil did not. There might be something there the experts have missed. 🤔

      “Service Emission System” & “175 miles until “65 MPH Max Speed”

      It's not that it sits for extended periods. I drive it every couple of weeks. However, I did consider draining the DEF and replacing it.    Don't you get a "Poor quality DEF warning" if its bad?

      Try draining the def and relacing with new if it has been sitting for a long time. Def does go bad after a little while.

      2015 Silverado with HUD retrofit/upgrade.

      By Thestonedone · Posted

      Thanks @Viktorrocks15 if you are still out there.   I followed your instructions and worked out great, went to the scrap yard and procured 2016 escalade cluster, hud, bezel, and switch. Got lucky and found a Camaro in the u-pull with the HUD bezel.   I made my own harness with these diagrams: https://www.gmupfitter.com/wp-content/uploads/2022/10/23_Escalade_Escalade_ESV_Electrical_Body_Builder_SM_en_US_2022OCT25.pdf   I used escalade cluster because its the best one that will work IMO. Still need to get it programmed but it looks really good.
