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.

oh no theres definetly someone there reading them. I got a call from her executive office about 2 days after I sent the email and someone was assigned to my case

Unfortunatly alot of us are going through this and GM just isnt accepting that there is a problem with these trucks. They are fighting it by saying this is a normal characteristic. Im going though the same thing and trying to give them the opportunity to make things right but from what I have been through already and seeing what others have gone through they are not playing nice. I would shoot mary barra an email and have someone from her office follow your case from the start, it may or may not help. The squeaky wheel gets the grease and it would help to get loud about this.

It only takes a phone call to open it right back up within 60 days.. I want them to step up and take care of there customers and give me a solid deal on a 2500 instead of treat us like our problem is "a normal characteristic". I am just tired of dealing with this company. I completely understand how it destroys the value of the truck by them having to lemon title it. I would hope they understand that I am giving them one last time to settle this otherwise i'm going all in with a lemon law case and Magnuson moss suit. Oh yea I forgot to mention they told me these new trucks are not designed to be luxury vehicles, that they are made like "trucks" now and aren't supposed to ride like a Cadillac. If I knew that a vibration was a normal characteristic for this "truck" I wouldn't have bought it and i'm sure no one else would either.

So I took my truck in for the final attempt the other day for vibration.. after 3 days all they changed was 4 tires and replaced all the rancho shocks on the truck. The engineer supposedly hooked up the vibration analyzing tool and by the frequency they determined the tires were the cause. Changed all four tires to bridgestone duelers and still showed a vibration.. Changed the shocks and supposedly it fell within their specs. I picked the truck up and took it on the highway and found that my vibration between 40-50 was noted to be 60 percent better but not fixed. The vibration at 70-85 was the same and not fixed either. I was told that the GM engineer was not required to fix the vibration from 70-85 because it was over the posted speed limit and it is not legal for them to exceed the limit of 70mph!!! I was floored at their response. I'm working with them now on a replacement but in order for them to work out a deal with me I had to close my BBB case.. I closed it and and will be negotiating on a 2500 but will have to spend more money to get into the truck I want. We will see what happens!

Did someone from GM call you and offer this?

It was the district manager of after sales. The general manager and service manager had been passing the information to me on the deal. If i known it was going to be this much of a headache I would have just taken the deal.. but right now my truck is in the shop again for the final repair attempt and the GM engineer has had it for two days. Not sure if their able to fix it or not. I should just email the DMA (I have her information) and see if she will give me the same deal but Im thinking of getting my money back and leaving GM just because of the way I have been treated.

I dont think it matters, its up to the district manager of after sales for that dealership.. my dealership called me after they found out I filed the BBB complaint and said the DM said the deal is off the table since thier is a complaint at the BBB..So now I am dealing with someone from GM resolution dispute office and thats what they offered me

So I went to the dealer last week to see what kind of deal they would work for me. Manager of after sales said pay the difference in MSRP for a 2500 duramax minus $1000 customer satisfaction money.. I said give me an extended warranty and/or 0 percent and I will sign the papers... Apparently they didnt think my vibration problems along with the other problems ive had totaling 35 days in the shop were serious and they said no so I filed with the BBB. Today someone from GM calls after the BBB complaint and offers me a WORSE deal.. difference between 105% of msrp for my truck MINUS milage which works out to be almost the MSRP for my truck. So now they want me to pay the difference and arent giving me the 1000.00. What incentive do I have to NOT file a lemon law suit. Cant believe it.

[email protected] is who everyone with this problem needs to send their concern to. Marry Barra is the CEO of general motors and I got a phone call from someone in her office a day after I emailed her about my case.. May be worth sending an email to every one else on this page http://www.gm.com/company/corporate-officers .... The squeaky wheel gets the grease and we are not going to get answers until they really understand the magnitude of this problem and how unhappy we are with these trucks. I for one and fed up with the way GM is treating me and everyone else. Please file a complaint on http://www.nhtsa.gov BBB Autoline is your next step if you are not getting results with your dealer and district manager of after sales.

So after filing with the BBB and sending the motor vehicle defect notice last week I got a call from someone in GM's resolution office that they are gathering info for my case and to schedule a final repair. Through conversation the gentlemen I was speaking to referred me to page 4 of the warranty booklet specifically the part that says "Repairs Covered, The warranty covers repairs to correct any vehicle defect, not slight noise, vibrations, or other normal characteristics of the vehicle related to materials or workmanship occurring during the warranty period. Needed repairs will be performed using new, remanufactured, or refurbished parts." I could not believe this response from GM. They really are not trying to keep customers. They expect us to deal with this vibration and claim it is normal!! We will see what happends during the final repair.
