Well, I just had an issue (actually twice now). I have a 2014 GMC and the door locks will not lock, nor will it lock with the fob. Yesterday, I had to lock the back doors by pushing the knobs down, and lock the front door with the key! Would not unlock with the fob. Had to unlock with the key. Lo and behold, later, it would work. Anyone have this issue before?

 

One other time it did this and it was in a thunderstorm, thought it was just a fluke..... now it did it again and was quite a pain.

 

I guess I will have to make an appointment with the dealer. Anyone have this issue before? Thanks.

I'm having the same problem - 2014 Sierra. About 4 times a week it doesn't start and says to Service Theft Deterrent. Been to the dealer and they say it's not thawing any code, so there's nothing they can do! Writing GM tomorrow - we'll get this solved.

Mine has done it several times now. The drivers door is the only one with a key hole, so have to push/pull the lock knob on the door for each door, then lock the drivers door with the key. Have an appointment next week. Guess we'll see. Thanks.

Well it has happened to me as well. Twice in 1 day. (last night) The truck is scheduled for some other work (recalls) and horrible headlight performance at the dealership next week. I mentioned it to them when they called to set up an appointment and they said they would check into it. The first time it happened i had to use the remote start from inside the truck. The next time i had to flip the key 180 degrees and it started. If they/ figure anything out i will update for others to know.

Crap, you might wish you had a "theft encouragement" system in that truck instead!

My 2014 Sierra has been doing this for weeks. About half of the time. Takes 20+ turns to start truck. It all started the day of my first oil change and dealer updated my software. Dealership kept my truck for several days. They think its fixed but it seems to have gotten even worse. Any known solution to this yet?

I may have missed it but has anyone tried using the other key when this happens? Could just be the transmitter in the key going bad.

 

The door lock issue may or not be related, no clue there. Mine has failed to unlock the doors once also but hasn't happened again.

This happened to me once, the dealer towed it, ran it on the computer, no codes, but guess what!? They had to tighten the negative battery cable, it was loose, and never happened again, crossing my fingers.....

Had the same issue happen. First time was a couple of weeks ago and today it happened twice. First time just kept turning key and it finally went. Today hit door lock and unlock and it started. Doesn't give one much confidence especially when it was -20 today and winter is just starting.

I had the same issue and when I brought it to the dealer they said it was because of my LED license plate bulbs. I laughed at them and brought it to another dealer who did some kind of update and it never happened again.

A shot in the dark here. Similar problem with my trans am one of the shock sensors was acting up did some research I had to get into car lock doors roll windows up put key in ignition turn to on not run keep in this position for a couple minutes and it clears codes. Might work. Good luck.

About a month ago, it happened to me one time and the radio display was blank at the same time. Next time I drove the truck and since then I haven't seen it come back. I think it was caused by the Range AFM disabler I had plugged in, because it also caused service stabilitrak and brake assist messages too.

      2019+ Brake failure, it's complicated

      By needafix · Posted

      I'm not sure if this should be a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - AC Delco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles, 119k total miles.  When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so I did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out, it could've been the wrong fluid. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material, scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance. I had a panic stop prior to this issue which may have contributed from what I read. And on the first attempt to bleed and hydraulic test the scanner listed things to look for and one was any gaps between the pad and rotors which I did notice on the RF corner and I removed the outer pad (where the gap was) cleaned it and the hardware and didn't see a gap after that but will re-check it. I read that if pushing the caliper pistons back then you're supposed to open the bleeder so as to not push fluid backwards into the abs module or it will damage it. If that's true then that's also a possibility from the previous owner having the brakes changed before I got it. I'm using an XTool ip500 scanner. Any suggestions, questions and comments welcome.

      Next Friday will be my 6 week point from my right knee replacement.  The surgeon says it will be fine if I choose to drive after this checkup.  I know I could drive now but best to do as my surgeon (and my wife) tell me.  Richard compared being 62 to 72.  I remember when I was in my early 60's I was experiencing slow but regular decline in my mobility.  Thanks to good medical support,  i continued to fight the speed and spread of this decline. During my 60's I worked on non-surgical methods and just when I turned 70, my orthopedic surgeon recommended joint replacements.  In a little over a year, I had one shoulder and both knees replaced.  This hasn't been a terribly fun experience, but worth the discomfort as my future mobility health trajectory has reversed.  It is a treat to now be watching my mobility. balance and confidence steadily improve!
