Had mine towed into the dealer, even with the bulletin being presented, my service advisor said he thinks it's something else lol. He mentioned it may just be my key fobs needing to be reset, I don't doubt that cause it did say on the screen that my fob was missing. Definitely a little bit of a deeper problem than my key fobs, I'll keep you all posted on what they present to me when I pick it up.

Truck is fixed as far as I know, even got an oil change, and is back in my drive way after less than 36 hours after drop off. The BCM issue was the culprit, and apparently this update is meant to be done at the vehicles first service. At 5K I hadn't had my oil changed quite yet and didn't get in prior to this issue occuring. Here is a shot of the tech notes about finding the codes and his resolve. Lines up almost perfect with that bulletin.

Something similar happened to me. Went shopping with the kids and several times used either the app or the key fob to start my Yukon. Last go round started it unlocked it loading my bags got in to hit the start to put in drive and it went blank, then kept saying press start again and it would all light up but not start push again and it would go off. Tried the app key fob sitting and waiting and nothing. Used instant and got a wrecker which refused the tow bc you couldn’t put the Yukon into neutral. Finally made son n law was able to make it to me disconnected the battery cable and reconnected and it started right up. I guess I will need to take it into a dealer bc the engine light is on but not flashing. Have had it just under 3 months.

Has anyone gotten a real solution for this yet?

Go back through this thread and you'll find a link to the TSB. The dealer can update the software.

I’ve been super hesitant to use the auto start on my 22 after reading the thread but the 90 degree plus Georgia days were upon us so I made the appointment with my local deal and got the BCM updated on Wednesday. I’ve used the auto start without issue from the app a few times already. Fingers crossed.

Service department didn’t seem to know this was an issue nor did they know about the bulletin so I printed it out from this thread and brought it in with me.

whole process was quick, I had just hit 3000 miles so I said screw it and had them do the first oil change and tire rotation while I was there and whole thing took less than an hour.

It’s been about 2 and a half weeks since I had the update done and I’ve remote started from key fob/iPhone App and Apple Watch app a ton of times (stupid Georgia in the mid 90s really killing me) and I’ve had no issues at all.

I played it safe after reading the initial post in the thread until a solution was found, now I’m relieved and just using it as I normally would have.

Had mine updated with the fix on June 9th and it's been working perfectly ever since. Prior to the fix I had the issue happen to me twice in the first week I had the Tahoe.

That reminds me of a weird occurrence that happened to me when I tried remote starting for the first time 3 months ago when I first got my AT4. The vehicle started with no problem, but the dash and everything else didn't turn on. It kind of freaked me out, so I panicked and turned it off using the remote starting feature again. I then started it up the normal way and it was fine. Since then, I haven't tried to remote start it ever again.

The dash doesn’t come on with the “remote start.” If you remote start it, you have to still get in the vehicle (with the engine running), put your foot on the brake, and hit the start button, which will turn on all the accessories and the dash.

The issue this thread is about is that when the second step above was done (foot on brake, hit start button), the vehicle engine turned off and cannot be restarted.

I haven't had any issue with mine since it had the update done. Auto start has worked great since! It's a must for us out here in Phoenix when temps hit 118°!

Same, had the update, no issues since

Is there any way to tell if you are on the current version? I took my 2022 Tahoe RST in for its first oil change and asked them to take care of this issue. They said I didn't need an update and the remote start was not creating any error codes. Any one else experience this at the dealership?

Unfortunately, I am still afraid to use remote start.

I would guess they have no idea at all about this issue and are just saying that.

Print the referenced TSB, or give them the number. Then tell them you want the latest BCM calibration so you don’t have to be worried you won’t be able to start after using remote start.

Sorry to hear it. Hopefully your dealer has a lead on a fix. Picking mine back up tomorrow but won’t risk using the remote start until they have a permanent fix.

2022 GMC Yukon XL Denali won't start after trying auto start!
I was at a birthday party and tried to start from a distance so I wasn't sure if it has started or not. Climbed in and pushed the chair AC button. light initially came on them went out. I put my foot on the brake, pushed the button, the blower motor came on to the high setting and that was it...
Couldn't turn it off or down. Key fob worked except for the panic button and of course, auto start. If i just pressed just the start button on the console the dash lights would come on but that's it. Bluetooth also worked. It was as if it was stuck in auxiliary mode. Motor would not turn over.
Ended up disconnecting the negative terminal for 10 minutes, re-attached and all was reset.
It's my understanding that the 2022 I have has the new updated software that comes in all of the new Hummer EV's so......WE apparently are the guinea pigs for GM...WTH???

This happened to me the same Day I drove my vehicle home from the deal back in July. We told them it was a BCM issue and they brushed it off saying it wasn’t and that there was no issue with the vehicle. Fast forward to yesterd (9/9/22), parked at a Wendy’s drive thru with the car still on, paid for my stuff and shifted to D, and issue with the shifting system came up, and it automatically put the car in neutral. Couldn’t shift it back to Drive so I put it in park and turned the vehicle off To see if it would reset. Nope. Car does not start but all the dash lights come up And everything. So embarrassing to be stuck cutting off drive thru traffic. I then get an email from onstar stating there’s an engine transmission issue and to service the car in one day. Of course the tow truck doesn’t come until after the closest dealership is closed.

Was told today when I called the dealership for an update that they’re backed up and their engine technician (one one) doesn’t work Saturdays. Says ill
get a call Monday of when they can even look at it but it won’t be for at least another 4-5 days after that.

Also just wanted to say that prior to going to Wendy’s I had remote started the vehicle and It was fine. Im not sure if the auto stop had something to do with it plus being initially remote started.

I’m not sure you are describing the same issue the TSB in question described. That issue was:
1) remote start the vehicle
2) Enter the vehicle with your fob in possession
3) Put foot on brake
4) Hit start button
5) Engine goes off
6) Engine cannot be restarted (waiting 30 min or disconnect/reconnect battery solved it)

A BCM software update fixed this problem.

Yes this is exactly what’s been happening. Just happened again. I’m so done with Chevy. This is the third time, the dealership told me they updated the bcm obvi not if it’s happened after the fact

 

[22CTHC]

Has anyone been able to get out of their purchase or lease? This is the third time it’s happened
