Thanks to everyone, problem solved.

 

Take a look at the boat I have been building for two and a half years. Go to packsail.com

Sorry from the beginning I believed you. But thanks to everyone here the problem is solved? Was this real? I'm VERY sorry if this is real and I have accused you of being fake, but what was this sudden resolution on the issue?

Wow, not good. Notify the dealer immediately! Something has obviously malfunctioned. I would suggest not driving it until the problem is fixed.

Why would OP want to even come back? The way you guys are so quick to pounce on someone. The guy doesn't visit internet forums like this, but when he does for the first time, just looking to see if anyone else might have seen this issue, everyone wants to pull out their "BS meter". Well quit playing with your BS meter. It's no wonder why I'm beginning to hear talk around that GMT is not as friendly as it once was.

 

OP and I have had on ongoing pm back and forth trying to convince him that this is a decent place. He posted his website because after he told me his background, I told him he should introduce himself to others here on the site. He's not here to sell a boat to any of us

 

Here's just a little of what he let me in on:

 

A little about me:

I am an ex Marine pilot with over 600 combat missions in Vietnam

Also a retired Merchant Marine Ship Captain

I have a website, packsail dot com

 

 

 

The guy was shot down like 4 times and at age 72, he has gotten into designing/building catamarans. What will a lot of us be doing at 72? Probably sitting around and crapping diapers. :)

 

Be patient lets see what else OP posts if he does. I wouldn't blame for not coming back. He owes us nothing after the way he has been treated by some on here. And yes some of your posts have been deleted because they served no purpose other than to attack OP.

That's what I was hoping for, but I just didn't understand how all of a sudden thanks to everyone here the problem was resolved.. I see now why he mentioned his boat link, but unfortunately whenever people usually post links to their businesses like that it IS for something sub-par. This is obviously on the up and up, as I thought it was from the beginning. I feel bad I doubted my instincts now.

 

I hope the OP does come back and we all get a chance to know him, and hopefully show him more respect, which he clearly deserves.

 

To OP and person I quoted:

 

Thank you both for protecting me. You are both heros.

Ok. OP sent me a PM clarifying things a bit.

 

 

My problem was solved, not the truck's problem. My problem was that the service department checked out both of the truck problems and said they could not duplicate either the transmission problem or the unintended acceleration problem, therefore there was nothing else they could do. Then I went to the service manager and complained that they need to do something more to try and solve these problems. He said he would check it out and call me. Two days later the owner of the dealership called me.

 

He said that they want to give me a free loaner truck just like mine and have their top service technician drive mine every day for weeks or months to see if he can duplicate either of my two problems. That solves my problem, regardless of the outcome. If they come back in two months and say that they were never able to duplicate anything, I will be satisfied.

Wow, so you are going to let a dealership drive your truck for 2 months while you make the payments on it. That wouldn't fly far with me.

He got a free loaner just like his, that would work for me. Be a good time to see the US, driving vacation time.

I've had my 2014 Sierra nine months and I just had the same thing happen with my truck. I kept hitting the brake pad and nothing happen. Well, something happened. It's called a Ford Taurus and he then was pushed into a Lexus. This happened tonight so we'll see what the dealership says. I won't drive it until its been thoroughly checked out and they sign off on it.

I am not going to dispute whether the truck's wheels was still engaged by the engine's driven inertia, but I can honestly say this truck has issues downshifting when braking at times.

My transmission hesitates at times not knowing what to do, it feels like it is holding back from downshifting.

I have had to do a few quick brakes when traffic light change, appling brakes the vehicle lags from downshifting and always feels like it is in a higher gear than required. This is how they are reaching their amazing numbers for mileage, however this vehicle really only drives proper at highway speed except the "shaking and vibration issues" all other daily driving I have experienced early upshifts to get the mileage , and delayed clunking downshifts that keeps the vehical's forward inertia locked.

So yes for Sue's claims this might feel like the car is still being driven when brakes are applied.

I wonder if these shift solenoids, or the transmission module has changed since last years model, because this transmission behaves much differently laging at times. I would have thought that if one applies brakes the transmission's forward inertia should be realeased starting downshifting immediately, however I have witnessed in my vehicle this seems to lay for some folks including mine.

I am still standing by the fact there is a leaking interal pump seal in some of these trucks, causing incorect pressure for solenoids to read and act on, or faulty cheap solenoids like the Dodge Ram had a few years ago.

I think GM bought from same supplier, but cannot confirm this though!

I bet that GM acts quickly getting their new 8speed into 1500 model asap, as many have been unhappy with the way this current transmission is preforming, and GM knows of more serious issues then we are aware of.

I can believe others claimes, of forward inertia but not the engine rpm above idle range.

This is my humble opinion.

I can feel for anyone has something like this happen. A couple of years ago my truck decided not to idle down when I pulled into a parking lot one day. Nearly hit the vehicle parked in front of me. Thankfully it never happened again but if I wasn't paying attention that day it could of been a real bad situation. Hopefully the OP gets some answers and resolutions to his situation.

This is NOT BS, my truck did this several times...got the the "no light on, no problem with this truck, can't replicate" speech by some idiot service manager. Why on earth would someone make this up?! I am just coming across this thread tonight for the first time, I explain that I had the same issue here:

 

http://www.gm-trucks.com/forums/topic/162450-does-your-2014-do-this/?p=1478378

 

I made that post on July 16th, never in my experience have I had a vehicle do this. But, to this date I haven't been driving it because its been at my dealer for water leaks, and other various issues for about a month now.

Hello sinnerz,

 

I'm sorry to hear you've experienced this same acceleration issue in your Denali along with the other various issues. I know it's very inconvenient to be without your vehicle for a long period of time. I'd be happy to contact your dealer for a follow up on your behalf at any time. Don't hesitate to send a private message if this is something of interest. I'll be on the lookout for updates in the future.

 

Sincerely,

 

Eddie A.

Similar experience as this can suddenly happen to anyone. My wife and her friends took my old '02 Silverado on a road trip a few years back. She prepared to exit the interstate and turned off the cruise control. The truck started accelerating as she entered the off-ramp. She tried several things before shifting the truck to neutral and turning off the ignition. Pretty calm considering a truck full of screaming women. She called AAA and had the truck towed 200 miles to my local Chevy dealer. Here's what they found:

The State was chip-sealing the highway and a rock bounced around under the hood until it fell perfectly under the throttle stop (not sure the exact term) on the throttle body. It was a million-in-one shot. The service department had never seen anything like it. In theory, that rock could have fallen out during the tow and then it would be the old "no problem found" scenario. I totally agree with the moderator on cutting the OP some slack as these things really do happen. I realize this is an old topic but did the OP ever get an answer on what caused his issue?

      Some Assembly is Required

      By Grumpy Bear · Posted

      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

      By Grumpy Bear · Posted

      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

      By Chuck FB · Posted

      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.

      Software Update

      By Chuck FB · Posted

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
