Electrical Issue? Dealer cant figure out.

I have a 2018 Chevy Silverado 1500 LT Z71 with 8000 miles. No modifications. Great truck, almost no issues but...

 

I have owned this truck for 7 months now, and for the second time in the last couple months, it has left me stranded for around an hour each time.

 

When i start the truck i receive the "Power steering reduced, drive with care" message. But unlike others i have read about, i can not turn the steering wheel with all of my strength. 

 

Also the truck will drive forward in this state, but not reverse, nor will the back up camera come on. And the AC and blower wont turn on unless i spin the dial a few times.

 

Each time i have opened the hood and pulled out and plugged back in all the (really hot!) fuses and after about an hour the issue goes away and i can drive again. Why would the fuses be so hot just sitting in the parking lot, maybe they always are. who knows.

 

I took it to the dealership and they are trying to recreate this issue, but since its only happened twice in 7 months that's not likely. So they told me next time this happens to have it towed. How inconvenient is that though!

 

Cant they run diagnostics or troubleshoot with the many symptoms the truck has in this error state? 

 

I was hoping someone here has an idea i can tell this dealership to try since they don't have ideas of their own.

 

Thanks!

They want me to wait until it happens again and have it towed. Is that really a solution? Talk about inconvenient.

 

So i'll inform them to check all the ground connections

 

Any other ideas?

Just FYI -- the ground issues are discussed in PIT5405.  Your dealer has access to this so tell them to follow it.  There are 4 or 5 electrical things that is has them check.

I have the same issue. 2018 Silverado 1500 LTZ. This happened to me on the second day I had the truck. It's happened 5 times so far and has been to the dealership every time with them telling me they don't know what is wrong and can't duplicate it. They did the service bulletin to change the grounds and check for burnt wires. That lasted 3 months then it did it again. Contacted GM for buy back under the lemon law and was told today they denied my case.  I think there is more than just bad grounds with this issue.  I. Not a happy person right now.

    • Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.       
    • We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper. 
    • Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money". 
    • I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back. 
    • That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
