I have 25k on my 2014 truck which lives in my attacher garage and recently its decided to come alive.  With one set of keys out of range and the other sitting in the center console my truck started on its own, ran until it came up to 160 degrees then shut off. That was Tuesday, 3 days later I came home to find that apparently it has done it again as the doors are locked and my garage smells of fumes. When I called the dealer they Said it has never happened to anyone they know of. When I called Onstar to see if they did it I was told they can only unlock the doors, not start it. Any ideas??

Did you happen to buy this truck used? If so I would suspect that someone has the onstar remote app setup for it on their smartphone and never removed it. From the onstar phone app you can lock/unlock the doors - start/stop the engine - turn on the horn and lights   If they never removed the app I could see this happening.

Your neighbor got a GM vehicle in their driveway/garage? Does yours remote start when they remote start theirs? I don’t care who says what there can only be so many frequencies for these things. This is common with some garage door openers.

 

Interference from another electronic device?

Jaded X wife? Mad at you teenager? Pissed off service writer at stealership? Lost cellphone?

 

Anybody know are these trucks hackable? I’ve read about this with other manufacturers hackers can raise all kinds of havoc including shutting off the vehicle in motion. Is OnStar hackable?

 

Original battery? There has been posts on here about suspected  low voltage causing weird electrical problems, especially since your fob is in the truck?

 

Truck is mad at you because you don’t drive her? She wants to roll.

 

Since I now know the key is in it what is your address? Just kidding! Maybe...

I know all of my neighbors, only a new Honda which is always garaged.

No X, no Teens, They actually like me at the dealer cause I keep buying Caddy's.

Original battery yes but never had an issue and always starts quickly.

Truck could be angry but I stuck through her bad days.

Might have been someone that test drove it and set the app up just playing around.  Should be able to get a data log from GM remote app as to when the app has been used to send commands to the vehicle and from what smartphone number? That would be my first / second / third and fourth effort. Most likely you will have to try several times to get some intelligent life on the other end of the phone.

I doubt someone that test drove the truck 4 years ago all of the sudden is starting to F with it. 

 

Are the window open in the truck and any animals living in the house?

FINALLY!! After refreshing my brain by rewatching “Christine” I was wondering when the sequel would come out.

But on a serious note, name it Christine, accept your fate, and feel privileged because you got the first and only autobot exclusively from gm. Cheers!

Where I used to work, they had a 2015 Dodge Cummins that got possessed twice. It would cycle the starter several times a second(that was a terrible sound), then start itself, shut off on its own, go into gear on its own, and a lot of other things, all with no key in the ignition. Dashboard looked like a Christmas tree and the gauges did whatever they wanted. 

 

If my memory serves me right, it was a ground issue both times. Maybe that's what's up with yours? Other thought is maybe a short in the ignition switch or computer?

No pets, truck is closed up tight, garage is totally finished and you can eat off the floor.

 

Odd that you mention ground... A couple years back I had problems with this truck for over a year, left me stranded 5 times and towed to shop under warranty. After 6 trips the dealer felt sorry for us and wanted to lemon law but they later that day found the the negative battery cable was not crimped at the bottom of the cable and it would slide in and out of the plastic sheath causing the truck to die & run with temp change. New cable and its been fine for a year, now this. I asked the dealer if they could change the code and remotes to correct and they thought not. Its now almost a daily thing where I find it running or at lease the doors locked remotely. The batterys have been out of the remotes and the keys not near the truck. NO one has been in my home so ...

That is weird. You may have ghosts in the house. Call a medium to chase them away.

 

Sorry, the DW has me hooked on some of these ghost chasing shows.

Try disabling remote start by unlatching the hood to see if it does it again!  Is your garage attached to the house? If so you should always unlatch the hood as a precaution so you don't all die from carbon monoxide poisoning.

      2024 SILVERADO 3500HD DURAMAX CLOGGED DPF AND WONT CONNECT TO TRAILERS

      By ManyCamaroz · Posted

      I had an issue with a new 1985 Z-28 some years ago. The 4WDB's were less than adequate when purchased IMO.  I had taken it in for small warranty services and asked them on three occasions to check them. Each time is was "could not duplicate on the service ticket. The warranty ran out about a month after my last visit and had to take it back for warranty rework. I again complained about the brakes. Well, low and behold, this time they determined the rear calipers were sticking and gave me a quote to repair. They had records as well as O had receipts of each time complained about the brakes while still under warranty. My dad was a life long body shop owner and told me to keep my cool and tell them that I wanted to speak to the GM Regional District Manager. The service manager disappeared for a few minutes, came back and told me they would replace the calipers free of charge.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      I decided to give it a shot and see what sort of a gong show it would be to a pan drop themed oil change on my 2025 gas truck with the 10 speed. All indications I had seen so far was that there was no way that pan was coming out of there due to the cross over exhaust pipe not allowing enough clearance for the back end of the pan to duck out from under the valve body since it hangs lower than the pan to trans mount flange and certainly the filter does. I never touched any of the exhaust mount hardware at all, be that the engine manifolds to Y pipe, the bracket on the side of the transmission, or the two bolt flange further back behind the trans/transfer case. I put the truck up on four jack stands as there was no way I was going to struggle with that lack of clearance under the truck. The truck was cold as it had sat over night so all the trans fluid had drained to the pan, so I drained the bit of oil that would come out of the level check plug at the bottom near the front of the pan and put the plug back in to reduce the ensuing mess after that. Then took out all but one bolt front and rear and then pushed up on the pan and took out the remaining two bolts and then let the front of the pan tilt and spill out most of its contents into a drain pan. I then popped the pan gasket off its two locating nubs and kicked it a bit to the left side so it was no longer on the flange of the pan to get all the clearance I could and managed to get the pan slipped out of there by swinging the front of the pan to the right but keeping the rear part of the pan inline if not slightly to the left of its mounting flange area and lifting the front of the pan enough to keep the rear part of the pan low enough that allowed the pan to "JUST" slip out without forcing anything. I installed a new trans filter and seal and as per GM instructions on this site I torqued the two bolts to that 44 inch pound goal ( they take an 8 mm socket ) In reversing the pan procedure after I had cleaned up the pan both inside and out completely ( touching the outside of a dirty pan and dealing with installing a gasket at the same time would be a disaster ). First I slipped the pan into place and yes it took me a while as it won't go unless its slid in just at the right angles, then once the back of the pan was into the area of the flange mount, I went and got the gasket and then threaded that through the front of the pan and feeding it under the filter etc and finally working it onto the flange of the pan and lining up the two locating nubs to drop into the pan. Then lifted the pan up into place and get a couple of bolts started and check and make sure the gasket is where its supposed to be as the bolts were being put in. I never used any power tools as I don't have any of the whimsy little drive guns, I use what looks like a small screw driver handle with shank that has a 1/4 drive on the end of it and added an extension and those bolts use a 10 mm socket as some times power tools can bite a person if used on delicate parts ( torqued to 80 inch pounds ). Also should note as per rules around pulling the add plug out first, yes I cracked that loose with a 8 mm Allen bit socket on a 3/8 slim head ratchet as there isn't a lot of room to work with there either due to the exhaust on the right side of the trans.    I already had delco ULV oil on hand and of course the quart bottle pump wasn't made for those small cap threads so I had to use some other containers that the pump would fit and keep transferring oil over into them so a wasted exercise there but indeed the small pump did work just fine as ULV oil is thin and easy to pump in summer time weather. I put in 9.5 quarts as per prior minimum recommendation and yes that cut it pretty close as once I had the truck ( off the jack stands so its level ) and the trans oil up to 167f , about 6 ounces came out but a level kit or what have you could throw it off just enough that it wouldn't be enough oil so probably that 10 quarts is a good amount to put in so one doesn't have to add more oil as when its hot I sure wouldn't want to be adding oil so would have to let the exhaust cool. All I do for warming up the transmission is sit there with it in park and rev it to about 2500 rpm and it takes close to 20 minutes to get it up to that lower limit of 167f, weird how it will warm up more doing that then by driving it, I am not real keen on power braking the truck to get the temp up there and don't seem to have to either. By the way I only have 9000 miles on the truck so probably not a very good payback on doing it that soon and the magnets had such a minor thin layer of fines on them so that was good to see and the color of the oil was a darker red then new oil but still looked very good as it should and I've not done any towing with it so its been living a pretty easy life so far. The filter is made in such a way that its next to impossible to pull out the filter media but there certainly was some fines showing up there which makes sense give the trans having to break in.    I hadn't really planned on explaining this much of what I had done since there are various instruction videos kicking around or I think so, as the gist of my message as that by fluke or what have you, for some reason my truck has just enough clearance to slip the pan out from the trans. Of course there is no guarantee that other trucks like this in general will also allow the pan to be taken out without messing with the exhaust as I expect its probably a crap shoot if it will or won't, I was just happy to find out that mine would work and avoid all the other struggling and possibly damaging things in the process,

      Fog Lamps 2024 2500 HD

      By BCGM · Posted

      Do you fellas think Fog Lamps would  be a good upgrade for our 2024 2500 HD Custom ? As you probably know it did not come with them ,  Would you put in GM Chevy parts ? Do they get wired up to the switch panel ( Upfitter or whatever the correct terminology is ) on the dash ? Thanks

      It would depend on what you do to lower it.
