Found this TSB released last month stating there is a factory offered "fix" for those who want to do away with the idle time-out.

 

#21-NA-228: Full Size Trucks Idle Time-out Disable - (Oct 21, 2021)

 

Involved Region or Country

United State, Canada, Mexico, Middle East, Israel, Palestine

Additional Options (RPOs)

BTM

Condition

Some customers may comment that currently if the vehicle is left parked and running with the RKE transmitter outside the vehicle, it will continue to run for up to half an hour. If the vehicle is left parked and running with the RKE transmitter inside the vehicle, it will continue to run for up to an hour.

Cause

This condition may be caused by GM PEPS vehicles were designed with an idle time-out.

Correction

In certain situations, the customer will request that this feature be turned off because they need to extend their idle time. A calibration is available to eliminate the idle time out feature. If this calibration is installed, the dealer will need to print the Owner’s Agreement Statement attached in this bulletin and put it with the Owner’s Manual. This is a customer pay repair. The vehicle owner is responsible to be aware of any local ordinances that restrict prolong idling.

 

Important: The following needs to be a separate page in the bulletin and the dealer will have to print it out and place it in the glove compartment or Owner's Manual.

When the vehicle was produced, it came with the auto-shutdown feature enabled. If you are not the primary owner of your vehicle, please note that this feature may have been disabled by a previous owner. The vehicle owner is responsible for being aware of and complying with any local ordinances that may restrict prolonged idling. The vehicle owner can have this feature re-enabled at owner cost at any GM service center.

Interesting. I didn't catch that "feature" in the owners manual, but there it is, "Extended Parking" with the timeouts listed. Good to know. I'm fairly certain I hate RKE/rfid fob stuff now. Gimme a d

Gimme a dang key, and if I start the vehicle, I intend to leave it running until I shut it off! That's been the worst feature of this new truck.

I can see both sides on this.  It would be nice if it was owner selected (I.e. free).

 

I had an Impala with push button start.  I took a family member to the hospital.  Dropped off at ER and then went to park my car.  In my hurry to get back in the hospital, I did not shut off my car properly.  I did notice that when I hit the button to lock the doors that I didn’t get the right “beep” but I didn’t realize that meant the car was still running and, like I said, I wasn’t fully in my right mind.  Well, after 6 hours in the hospital, I came out to my car running.  I guess they didn’t have that feature back then (2015).  I think the option is well intended, but it shouldn’t cost money to knowingly override it.

Def going to be looking into this ASAP. I go direct to calls from time to time at my fire department and being able to not have to worry about the truck shutting off while on the side of the road which in turn kicks off my lights, would be great. Plus on those cold days, truck stays warm while we are out.

Thank you so much for sharing this! I had to pay $255.00 for this here in Canada but now my long distance remote start will keep the truck running up to 45 minutes. Why so long some may ask? Well is is below -30c here this week and 15 minutes doesn’t even get the motor warm let alone the interior. And the factory remote is good for about 200 feet. In hind sight for what I paid for the remote start  I could have subscribed to onstar for about 5 years but I hate monthly payments. Will definitely think about it for the next one but for now I am very happy. Now to just find a way to disable stabilicrap……..

I friend was telling me a similar story with her elderly (80's) aunt and push button start.  She had went grocery shopping and when she came home she was tired so she called her niece who lives a block away. Mary was saying she went right over to help Nancy unload the groceries. Upon entering the garage she found the car was still running, some 10-20 min after she arrived home. Nancy being hard of hearing did not hear the horn honk when she left the vehicle.  I am not sure if the new 2021 Jeep SUV's have the time out feature but it could have been a real catastrophe had the engine continued to run killing anyone in the home with carbon monoxide.  I hate the push button start.. I recall my dads first car had push button start, a 1950 Chevrolet but they still had a key. We have come full circle now everyone thinks that new technology.  LOL

A little button for extended idle time and turning off cylinder deactivation would be helpful. I’ve been in vehicles with a button for tuning off stop start. So what’s the deal?

So i had this TSB completed on my truck last Monday...much to my disappointment, it didn't work. I reached on one of the FB groups, and someone posted this TSB that they said worked. I'm going to contact my dealer and see if they can give this one a try. Just as a heads up for anyone else looking to do this.

Morning all...I had the dealer do the above TSB(21-NA-056) and I can confirm it worked. I did have to pay for the program from GM and apparently GM Tech gave the dealer somewhat of a hard time about getting it but they were able to get GM to give it to them. Just thought i'd give an update for anyone debating on doing this.

Mind if I ask what it cost?

The first time I went, the dealer only charged me labor which was $75. This time there was a charge from GM for the programming files and that was $100 but they didn't charge me labor for it so I'm in for $175 total.

If you have a key I don't believe it matters, the auto stop feature will still shut it down.  If you notice your key is more of a button than anything.  You don't have to hold the key in the start position until it starts, if you just blip it, the starter stays running until it's started anyway.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      True. My statement needs qualification. "For a shade tree mechanic, re-assembling the front engine to achieve a rough baseline timing of 0 degrees, as is approximated and indicated by common visual indicator mark alignment, measured with a human eye capable of 20/20 vision *with correction, I am reasonably confident that I have followed the outlined procedures/ prescribed methods for verifying baseline timing."   😉   In the end, the computer sets the timing, it's continuously variable based on sensor input, and the distributor only has a degree or two of physical adjustability intended for dialing in the final setting for cam ****** once everything is back together. But even that final value is acceptable within, I believe, +/- 3 degrees.   I thought my exhaust project was going to be a bear. To my surprise, the old clamps came right off last night, and I was able to unbolt all the hangers instead of having to muscle the rubber mounts. The old cat is ready to slip off the factory y-pipe. The rest is ready to come out with one or two cuts, and I've got a fresh blade waiting. I love living where rust isn't a thing.

      PF63 Oil Filters Going Away?

      I work at a Chevrolet dealership & hear it all believe me.  Just reads like there's going to be a fist fight over filters.  Can't get enough, continue!!

      Tire psi

      By Chuck FB · Posted

      I just can't think of the exact term GM uses for that higher gvw package without looking at the website but basically sort of a trailering package and I imagine it may also have been created to skirt around the licensing fee differences between a3/4 and 1 ton that apply in some states although ironically I believe in some states its the reverse that a 1 ton is the cheaper truck to license over a 3/4 ton. It makes no difference here in Alberta but oddly enough a 1 ton through my insurance company is a bit cheaper to insure over a 3/4 ton as its based on the insurance statistics they generate.    For sure when ever you do have the chance to weigh your truck and to be fair, try to have the fuel tank full or nearly so rather than give yourself a false sense of the truck being lighter by having an almost empty tank.    In my other comment I was mentioning stock sized tires and partly in case someone was reading this and thinking they could lower their pressure down to what your aftermarket tires are able to do with your empty truck as that is a vastly different picture in the leeway you have to play with for running minimum pressures while remaining safe. I will say also that its easy to see from reactions of truck owners that may have been more used to owning a half ton in the past or a car and be it on a forum like this or in person etc that they get so wrapped up in that placard pressure sticker that they can't get their head wrapped around the fact that an HD truck due to how much it can carry can also vary the tire pressures drastically lower than those pressures ( typically more so for the rear axle on stock sized tires ) when empty vs some car that isn't made to carry much so the tire pressures can't be lowered since it needs almost that much pressure just to carry the empty car.    If I ever do find myself in the states with this truck, I will only be too happy to switch it over to the US measuring system as then I will understand all the dash readings. The only thing that is off for me slightly with US measurements is US miles per gallon as I grew up with the Imperial gallon and to this day up here anyway speak in Imperial miles per gallon ( I don't do that on this forum though as that would confuse everyone for no good reason ).

      Tire psi

      By jgaudet99 · Posted

      Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol
