I have found that if you go to settings and then update and then check version info it shows the version info and if you repeatedly tap on the file name it will allow you to enter development mode. one it says developermode enabled you can go back to the settings page and you will see developer mode and there is a bunch of options in there. not sure if you can enable something in there but i did see USB debugging and that may be a way in.

Don't accept this.. Tell them you want every penny for the truck back you spent.. They are giving you what the law says for a lemon law.. But they know if they go to arbitration they will lose so tell them you want all you money back for the lemon and you want the new incentives on the new truck.. I personally wouldn't get another 1500 I felt it was Neccessary to spend the money on the 2500 diesel proven drive train.. Whether the body of the truck falls apart around it later on or not I know that duramax and Allison isn't taking a shit on me.

Yes I made them give me back the price I paid for the truck.. and then I took the new truck with whatever rebates it had at the time which ended up being more because the 2015.5 were coming out. I should have made them pay all the tag transfer fees and all that but I didint think about it at the time. The other thing I realized now also is that my credit score went down because of obtaining so many loans within a short period so my interest rate was actually a half a percent higher on the new truck.

I think we are on the right track.. we just need the file that is on the USB drive for the update. Then we can try and decipher it and then change the parameters, modify whatever we want, etc. Then we will have to figure out how to get it back onto a HMI module. Also is there any information or schematics available on your end for the HMI module?

And from what I understand is that the software in the hmi is updated through the use of an MDI and GDS2 through service programming software?

Can you get us any update doesn't matter what version? I will set up a drop box for you if it makes it easier. And if you need I can give you my vin number which has MY14 and navigation Can you get us any update doesn't matter what version? I will set up a drop box for you if it makes it easier. And if you need I can give you my vin number which has MY14 and navigation

HMI Software GMG2_12.6N146.4 and GMG2_12.N185 for the MY14 and also GMG2_14.1F105 for the MY15 if possible! Thank you!!

Is it possible to download an update from TIS and share for us to look at?

I got my situation fixed by giving my Mexican 2014 1500 back on a trade assist and getting into an American made 2015 2500 duramax. Pressure them into a buy back they don't seem to care about fixing the 2014s. Just a big waste of time. No problems with the 2500 so far with 1800mi on the clock

What was the deal they made you?.. Are you sure they "bought it" back or did they give you a "trade assist"? Usually if they buy it back they have to deem the truck a Manufacture buyback on the title and they are trying to avoid that like the plague. And also if they bought it back I think you have the option of taking your money back.

I not sold on the tires.. They road forced mine multiple times, indexed, and then finally ended up changing them all out for bridgestone duelers which road forced at 8.. I still have the vibration. The problem has to be further up the drive line in the transmission along with some frame beaming on top of it.

I think the three important people to contact are Mary Barra [email protected] the NHTSA http://www.nhtsa.gov and your dealership District Manager of After sales who will only speak to the GM or Service manager.

This is true. I started my BBB case and recently closed it so we will see what happens.. I do have the ability to open it back up within 60 days or start a new case if its longer and proceed if nothing can be agreed upon but I am going to give GM the benefit of the doubt one last time before I write them off forever.

So here is my take on this whole thing. I have found that GM likes to spin me in circles and heres why. When I was first advised to call GM customer care and start a case number I was assigned a customer service manager.. Every time I would ask this person for an update she would have to call the dealer and talk to them and then give me a call back a day later.. The information I was given was the same information I would get if I called the dealer and asked my self. Over time I found this was pretty much useless.. This is when I decided to take things to the next step and Email Marry Barra. I sent a lengthy email about what I had been through with a time line of events and who I spoke to. A day or two later I received a call from an executive office manager and was told she was now assigned to my case by Marry Barra and she would be relay the info back to Mrs. Barra. Well over time I came to find out that she was pretty much the same type of customer service person as the last one.. Would have to call the dealer to find out what was going on then relay the message back to me a day later. After a few weeks of talking to her I found she had no authorization to make any decisions in my case she was simply following along to relay information. As things progressed and I now had been going back and forth with her, the general manager, the service manager, and the owner of the dealership I had came to the conclusion is that the District manager of after sales(DMA) is the one who clearly is the decider of my fate with this truck. Once I filed my BBB case the executive office rep stopped contacting me and the DMA took any offers off the table. At this point I was told that no one could talk to me anymore because it is now a legal case. I got a call from GMs resolution department (extremely rude by the way) and was offered what the state would have allowed for a trade in only if I would have won arbitration. I told them this was a worse deal than I had already been offered. Through talking with this person I had found out that he was receiving orders from the DMA her self after I was told by her she couldn't talk to me any more it was in the hands of someone else! WTF GM... I filed my final attempt which is a requirement for the lemon law. They replaced all the tires and shocks and called it fixed even though it is not and is supposedly "within specs from 0-70mph". So now I have put my BBB case on hold and I am waiting to work with the DMA again to get into another truck because at this point I had decided it would be easier to take a 2015 2500 and call it a day because I would have went and probably bought one anyways after I got my money back. I really am over their games and If this doesn't get resolved quick I am going full force on a lemon law and I will buy another brand. This is their last chance to make this right. The lawyer I had sent my documents to for counsel is chomping at the bit for this case and wants me to pursue lemon law. Now GM knows if they buy back a truck and give you your money back there going to lose their ass on the truck if its lemon titled so I believe they are trying to buy these trucks back under trade in assistance to prevent this. The reason I recommend everyone send an email to Mary Barra and the NHSTA is because we will not get any where if there is no pressure put on GM to fix these trucks. Marry Barra's mailbox should be full of our complaints so that she understands how wide spread the problem is and puts the pressure on the right people. If only one or two people here or there complain our problems will get dismissed as we are just complainers and they will still use the excuse "oh this is the first time I've heard of this problem." My recommendation at this point is to try and work with the DMA if your willing to get into another GM vehicle. I my self will not take another 1500, 2014 or 2015, I don't trust the platform. I have however driven a few Duramax's and from what I understand is that it is the same frame, engine, and transmission that they have been using for the past 4-5 years so the kinks I'm assuming are worked out. The only thing that would make me nervous is the rest of the truck. Am I happy about being forced to spend another 5-6k to get a working truck? Hell no!! But at this point its this option for a proven drive train or to go through the hassle and time of going through arbitration, and possibly a law suit thats going to drag this on for another 3-4 months. I WILL go that route if they don't step up and make me happy as the customer service has been SHIT so far.
