This weekend my truck started acting weird. On Saturday there is a very intermittent zap or click noise that would come through the speakers. Almost like there is a short somewhere. When this happens and I am turning the steering wheel tries to pull back midline for about a second or two then goes back to where it was previously turned to. When I started the truck up on Sunday I had to re-enter the time in the radio but all stations were still programed into it. I noticed when the headlights are on and it makes that noise the headlights flicker a little bit. On the way into work this morning that noise was not there but during a turn on the interstate the steering wheel tried three or four times to return to midline during the turn. It happens so fast that is is finished just about the time you can react to it. Needless to say I am taking the day off tomorrow to take the truck in but anyone know what the issue could be?

Your symptoms are similar to others that have reported bad grounds, and/or bad battery cables. Here is one thread, but I believe there are more:

Yes I have been reading all of these. The only difference so far as I can tell is I am not getting any error messages that pop up. Or if they do I am not able to read them as I am to busy reacting to what is going on.

Took it to the dealer today. They were unable to find any codes. Although they did mention a TSB for the steering wheel jerk and said they looked and the connections were good. They want me to bring the truck back in on Monday so they can tear it down and find out what is going on. Said they would more than likely have it a couple of days.

So the dealership still has the truck. I have owned it a total of 23 days and it has been in the shop for 11 of those days. Called Wednesday to see if there were any updates and was told a couple parts had been ordered and they were still trying to track down the steering wheel issue. Friday they were still waiting on parts and they have not been able to make the steering wheel do anything crazy but were going to replace the ground wires incase that is the issue.

It would have to be a ground inside the cab if you lost clock settings in the radio. My uneducated guess would be the BCM ground which has the common ground to all your symptoms.

My son 15 suburban is acting up too. Very scary his wife wouldn't drive it with the kids in it. I'm sure there'll be a recall some day. In the meantime they all ride in his little car. The suburban is 18 K upside down so trading in is not an option. Bad deal for GM I can see this becoming a major problem when people start getting hurt because the can't steer the vehicle.

Hopefully they will pinpoint the problem soon. It sounds like some type of power surge is causing the computer to shut down and reset thereby losing the electric steering and other settings. Intermittent electrical gremlins are hard to diagnose. It really could be any number of things but my guess is that there is a bad diode in the alternator and they should check that first......been there done that and got the tshirt on a different manufacturers vehicle. Never got an engine code and it would never act up when at the dealership when under warranty, typically once or twice a month would just be driving along and it would hesitate / gauges would go crazy for a few seconds (sometimes it actually DIED) and then it would be fine for a while.

They need to report their issue! NHTSA is where you start.

The waiting game starts,they claim they finally fixed a loose wire. I offered to let them drive my SUV and switch but there're fearful. So it basically sits. The steering locking up is the reason.

How hard is it to detect a bad diode? I only ask because I had read that in another post and took it to a auto parts store and had them test it. He said it looks good but would not be able to tell if it was a bad diode unless it acted up when he was actually testing it.

I already filled out my form with them. Interstate driving and no steering was not that fun.

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      By C/K Man · Posted

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.

      Software Update

      By nfisherman · Posted

      I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip.

      Exhaust Question

      By newdude · Posted

      Fuel mileage?  That's all how you use your right foot.  Exhaust will give you sound.   Stock exhaust 5.3 is 2.75" diameter piping.     If the truck is nice and worth putting some $$ into it, I'd go for a Corsa catback.  I had one on my 2019 old body 5.3 and it was just perfect.  Zero drone, just driving around and cruising on the highway you'd think it was stock, but when you opened it up it was like a Camaro with the factory dual mode.  Corsa bumps their catback to 3in diameter.
