i have a 2014 Silverado with problems. Set cruise control roll down power windows cruise goes off. Put on directional with cruise and try to switch lanes cruise shuts off stabil trak comes on sometimes ripping the wheel out of your hand. Turn the steering wheel with the air on and the fan slows down. this truck is dangeruos my wife won't ride in it any more. Took it to a dealer, can't duplicate it. Told them there was a voltage drop when this is going to happen. Figure they would try to duplicate a drop in voltage see what happens nope they put another 150 miles riding it around. Called main customer service number told them about what was going on looking for tech help. Her response was I will call the dealer and see if you can ride around with them. If thing doesn't get fixed a lawyer is next.

I'm a GM World Class Technician and I get nothing but problem vehicles like this. I've worked on a ton of the 2014's with random electrical problems like this. You know what just about fixes them all?.........Battery cables! I replace both positive cables and the negative cable. I bet you if a technician pulls some DTC's they'll find a bunch of B1325 in a lot of modules. The code will be a low battery voltage code. Basically, there is high resistance in the cables not allowing the full battery voltage to come through, so when a module gets around 9-10 volts instead of 12-14, it does crazy stuff. I would also change the battery a well. I'm almost confident this will correct the concern.

Thanks Justin i have been telling the service dept. about the problems start with a voltage drop but all they want to do is go for a ride.

Take it to a different dealer or just buy a new battery yourself. Worth a shot. The factory batteries are pretty bad with a very short lifespan.

On issues like this (where the dealer doesn't listen) I type up a couple of lines detailing the issue - "Customer says ..." and ask the service writer to type my words on the service request. At least that leaves a good record of the problem for future reference.

 

Do not make your wording too long or the service writer won't want to type that much :-)

Sounds to me like they don't have anyone that diagnose it. You can try another dealer, or call the GM customer care line. Or request a field engineer to come to that dealership. Nothing is more effective than saying "I'm leaving with you until it's fixed, and you want a loaner car" [emoji23][emoji23][emoji23]

Taking the time to thank Justin. Convinced dealership to put new battery cables on my 2014 silverado (like you suggested )400 miles later and 3 weeks no problems. Fingers crossed. Thanks justin.......Tim

Justin,

I recently had a similar experience in my 2014 Camaro. It lit the dash up like a Christmas tree one morning. Steering, ABS, Stabilitrak, etc.. Steering went to about half power. Drove it about a mile to a dealer. They kept it two days. They couldn't clear it for a day. New BCM software. Finally, they called and said they cleared it. They couldn't identify the problem. I could see they had been in the trunk at the battery. I think they checked/cleaned the cables. The battery was only a few months old. There are a lot of these experiences posted over on the Camaro5 forum.

      Parking Brake - Automatic Engagement Questions

      By PunchT37 · Posted

      I have a `25, 1500 that auto sets on incline. Never knew that at first. I have the electronic shifter. Just think if it didn`t do that? Unlike a mechanical shift that you can muscle out of park, how would you get this thing out? That would be a problem.   What I found out later is, I don`t have to push the button to release. Just put it in gear.   Setting parameters? Don`t know if it`s possible.

      Parking Brake - Automatic Engagement Questions

      2023 GMC 3500 HD, SLE, 6.6L Gas, 4x4, 6 Spd Options:  SLE Convenience Package; Driver Alert Package 1; Spray on Bedliner; X31 Off Road Package; TRAILERING MIRRORS, HEATED POWER -ADJUSTABLE, AUTO DIMMING, WITH TURN INDICATORS WHEELHOUSE LINERS, REAR INC. REAR AXLE - 3.73 RATIO INC. GVWR, 11,350 LBS. (5148 KG) INC. FRONT AND REAR PARK ASSIST, INC. ULTRASONIC     I have been launching my new boat and noticed some things related to the parking brake.. I usually set the parking brake (habit) when on flat ground for typical driving.    When backed down on the launch ramp to launch the boat and I place gear selector into Park, the parking brake activates automatically. My second nature is to set parking brake manually and noticed I was turing the parking brake off.  The parking brake appears to be setting itself automatically.   I looked all over my owner's manual and only found references to being on an incline and manually setting parking brake, or at times parking brake will be auto engaged, but nothing specific to my situation.    When is the parking brake automatically engaged?  Under what specific circumstances?  Can the auto set parameters be changed?     I like the auto set feature.  It would be nice if always engaged when shifted into Park and released when shifted out of Park (like my wifes 2025 RAV4).   Thanks!

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.

      Some Assembly is Required

      Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.

      Software Update

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.
