Waiting 20 minutes worked

I have the same problem with my 2021 GMC Sierra. The truck has 9,797 miles. I will wait 20 mins to see what happens.

I also received the below text when the truck first started:

Diagnostic Alert: Service the Antilock Braking System in your 2021 Sierra within 7 days. Txt STOP to cancel.

I had the same thing happen to me, I drove 9 hours parked it, and then the next morning the steering wheel is locked up and my dash reads “ESC needs serviced, Power Steering Failure drive carefully”. It was undriveable so I scheduled an appointment with a dealership and called roadside assistance to tow it. I turn on the truck again 30ish minutes later to run some AC and lo and behold no error message and my wheel will move again. I cancelled roadside assistance and drove it to the dealership. They warned me that it had to be repaired the part that controls power steering isn’t communicating with the rest of the computers. The technician warned me that the vehicle was unsafe to drive unless repaired because the malfunction can corrupt other systems. We’ll see how it turns out since it’s still at the dealership but I wanted to post this because I know the dealership is a hassle. I almost didn’t take it in, but because of how adamant they were that I not drive it, I wanted to share so other drivers would get their truck checked out.

Thanks for the update. Did the dealership state the name of the part that needs to be replaced?

They replaced the electric drive rack and pinion steering gear, then they reprogrammed the PSCM. To be completely honest, I’m not sure exactly what all that consists of but I know it was a pretty time consuming job it took the technician 4.5 hours.

I encountered this issue this AM. I started my truck to go to work and got the "Service ESC" warning on my 2019 Sierra. I could(n't) barely turn the steering wheel with traction control engaged. I went back into my house and did an online search. I happened onto this forum posting. I waited 20 minutes as many on the post suggested. Then went back outside, started the truck...no indicators. Not sure what to make of this....

Not to sound like a broken record on this forum, but the exact thing happened to me last night with my 2021 AT4. Went to get a haircut, come out and all the codes everyone mentioned were up and no steering. I called the dealership immediately and they said to schedule a tow through the app. Tow truck shows up an hour later, and nothing is wrong. I said to tow it to the shop anyway, and of course I'm told they cant do anything because there's nothing to recreate the issue. I'm hoping like most of you, this is a one and done deal. I'm heading to Utah to take the truck on some trails, and I'd really hate for this to happen there, or worse yet, on the side of a mountain while I'm moving.

Hi there, same thing happened to me on a 2021 Silverado Trailboss. ESC and Power steering failure came up. I went on the forums.. waited 30 min and no problem. BUT i am taking it to the chevy dealer and have it checked out. I have 12,000 miles on it. Will update the forum here.

 

[gacampbell54]

I presently have a 2021 2500HD Silverado at the dealership for the ECS light being on.
Mine started last year only in hot weather when I started the truck, it would be off after sitting a little.
This summer it became an issue common except in cool weather. But did not reset after sitting. The dealer replaced the steering angle module today but that didn't fix the issue. The truck is still there as I was told they are talking to GM for guidance.
Will post again when new info is available.

Update
Dealership found the following: B99 SASmodule had only 2.3 volts on the supply ckt 2087 the root cause to be terminal #40 ckt 2087was partially backed out of connector of the I/P side of connector x225.reseated terminal within the body and that fixed the issue. So there you have it LOL. Kudos to the mechanic in troubleshooting. He received no resolution from GMTAC. He backprobed to find the problem.
Hope this can be of help to someone with the same issue.

Just had the same issue with not having power steering. Got in turned on the truck and of course Esc no power steering code and check engine light came on.
Looked up how to fix this thinking maybe lost power steering fluid or broke a serpentine belt but nope. Drove it home about 6 miles and checked the codes with my scan tool and it showed no codes, stored, current or permanent. I then started the truck after checking everything tbs and no codes and have power steering like the issue never happened. Didn't think about recording it I was to busy trying to fix the issue. This does happen, it happened to me today 8/3/22

Hey all, had the ESC code pop up on my 2021 crew cab LT 4x4 with 57,756 miles today. Coincidentally, this same code popped up while doing the exact same thing this time last year. We are out on the sand in Hatteras, NC. It cleared last time after roughly a half hour, and being on smooth pavement. This time, it isn't clearing, but we are still parked on the sand. I have the tire pressure down to about 18 psi, and what I was told last year is the the sand and low tire pressure messes with the wheel sensors... I will air the tires back up later today and see if the error goes away. The power steering is working perfectly fine, it's just the stabili track system that appears to be in fault.

I purchased a 2020 2500 with 3,600 miles on it. I drove it from AZ to MN and back with 0 issues. I pulled into a gas station and filled up, go to start it back up and I get the ESC error along with 0 fuel and brake errors. It wouldn't start up, I popped the hood and tightened the fluid tanks and called for a tow truck. 30 min in it started back up with engine light still on, so I still had it towed to the dealer.
the dealer gets it and sure enough 0 errors and they can't find anything wrong with it.

Oct 2022. We drove about 3 hours and next morning got up to continue our trip and had the ESC error and no power steering. While Rob popped the hood and found a chipmunk winter storage, he started removing pine cones while I found this forum. By the time he finished removing pine cones and checking for anything chewed, we had used up 20 minutes. So we started truck (2021 sierra elevation) and the error was gone. Back on the road. Good to go. I will send this forum string to the dealer on Monday.

What's most likely happening with your truck is a software problem. Complain to GM all you want it isn't going to fix it right away. They will probably come up with a new software fix within a few months and then the module can be updated. The good news is that if you had taken it in with the truck under warranty if you go out of your BTB warranty they'd probably still cover the reflash.

Whenever you have to shut the truck off and wait 20 minutes you're basically waiting for the whole truck to "go to sleep" and all the modules time out.

I hope this helps. I can do research on Service Information and see if there are any new bulletins about this issue. I just checked SI for bulletins but I'm not finding many about this issue. Do any of y'all have a DTC list for what specific DTC is occurring when this happens?

Thanks for your input. I have sent the link of this forum to our dealership and hopefully somebody gets back to me. Tracey

I have my report from my scan tool. This has happened to me 2 times so far. One at 480 miles and another at roughly 700 miles. Each time I have to unhook the battery for 20 minutes and it will be fine. Letting the modules time out doesn’t eork for me. The truck was purchased 1 week ago. This is unacceptable.

 

[rreese1269]

Same thing happened to me today. 2021 1590 trail boss 15,000 miles. Was parked for 48 hours turned it on no power steering and esc light on. Waited 1/2 hour works fine. Should I take it in??

 

[Redacted]

Mine has done this one time only, and that was over a year ago. Nothing since, but the dealership service people haven’t given me any confidence in their ability to problem solve.

 

[Ellis7577]

Might be worth taking a picture or video of you dash if it happens again. That way if the dealer tries to downplay it, you at least have something.

2020 GMC AT4, 5.3L, 10-speed, 32k miles. I was on a trip in early May, 5 hours from home. Bad timing for an electrical problem. I've never had a problem before, the truck has been perfect. I had just driven about 550 miles in the previous 1.5 days. We stop for dinner, come out and start my truck. The Service Power Steering and Service ESC light up the dash like a Christmas tree. Driving with no electric steer is both difficult and dangerous. But I limped it about 2 miles to our hotel and jumped on the forums. Sadly, GM-Trucks.com has an 11 page thread about this issue in 2019-2020 GM's. So strange, but the solution was to wait 20 minutes and restart the truck. I did that (it was more like a half hour) and sure enough, it worked perfectly again. Strangest damn thing I have ever experienced with a vehicle. Upsetting. That was at 30k miles (yes, I put 2k on in about 4 weeks). It has not recurred. I don'k know what happened, whether it downloaded its own software patch, "rebooted," or reset in some way, but it self-resolved (at least for now). According to others, some dealerships are saying they've never heard of such a thing, others are saying they've heard it but not seen it. It seems like one of those things that is common enough to be concerned, but not so common that a TSB was issued or a recall exists. I still don't have a good answer as to what happened, but am throwing this out there in case anyone else experiences it. Sent from my iPad using Tapatalk Pro

Just to add to the string. I have a 2021 GMC sierra 1500 AT4, Duramax 3.0L. Sat. the 11th while leaving my grandsons Baseball tournament I had the same problem. I started the truck, no power steering, service soon and the ESC light was on. I cycled the engine 3 times and still no power steering. I tried driving out of the parking lot but it was very difficult, not like the old cars before power steer, much worse, I stopped and called for my daughter to come get the kids. It was to dangerous to have them in the truck if I was going to drive it 20 miles back. After 20 minutes I started to truck to get some heat in it and the power steering was back. After the kids were unloaded I cautiously drove it home. Monday I called the dealer where I was told don't drive it and bring it in today. The service tech told me if it is not doing it now than there is nothing they could do. I told him it was a safety issue and a liability issue, I need papperwork and they could accept liablity. They decided to take it in and look. They reprogrammed soft ware. Just one more issue with this truck. Radio goes black periodically and resets. It makes it hard when you are using it for navigation. AND the issue with the Duramax 3.0L not starting, GM has no fix for that. NOTHING can be looked at if it is not happening when you take it in. A lot of money and you hope it is reliable, you have a warranty and you are told to find your own way home or call Uber or Lift. After 20 years and 13 new GM vehicles, it looks like time to go to RAM or drive a jeep like the wife. Very disheartening.
