Same break controller issues  on my 2022 Sierra.  
No help from Dealer, just given copy of PIT5948, and told GMC working on it, and told “sorry”. 

Welcome to the group, Murvaul!

I wrote to GM today and asked them for an update, I hope they'll give me some good news, there are around 4 months since the issue was acknowledged by GM.

I just bought a 2022 sierra 1500 for my business. I’m a contractor and tow everyday. No where did I read about this brake controller issue- but at 100km in my truck it started. No fix yet.

was told to just drive safe. Had the truck 30 days and i can use it for work?! Not acceptable by any means. Dealer booked me in for an aftermarket fix but then canceled it due to it not going to function. As of today- still no fix.

Ok. My replacement is scheduled for tomorrow.  I'll report back asap.  I won't be able to test on my camper until something over the weekend.  I'm dropping off tonight/picking up tomorrow night.  I'll ask for the part number as well.

 

The service manager is going to test it with the magnet tester there.  But I need to make sure it works myself on a trailer or 2 (mine and neighbors)...

A GM feildengineer came out a little over a week ago to look at my truck. He brought a new controller switch with him and swapped mine out. I have only had the chance to tow with it once for about a 15 mile trip. So far everything is functioning as it should. I am planning on doing more towing this weekend. I will post afterwards to let everyone know if the truck is truly fixed.

Hello everyone!

Received today an answer from GM CL Social Care:

Please know that your safety is of utmost importance to Chevrolet. As mentioned, GM Engineering is aware of the issue and working on a repair. We do not have any further update or ETA to provide at this time. We do recommend continuing to work with [your dealer] as they would be in the best position to provide updates once available. Rest assured we take your feedback very seriously and have documented your dissatisfaction.

 

So still no ETA after 4 months... Very dissapointing!

Just picked up my truck.  I did not get a part number, i will review the work order again tomorrow, but it didn't appear to be on it.  I'll try to tow this weekend (probably Sunday as we are pretty booked Saturday).

Ok. Was able to test this afternoon.  Good news.  No brake controller errors, gain was fully adjustable and the toggle was responsive each squeeze.   I didn't feel weight while pressing the brake pedal either when testing.   I've attached the details of the work order bur it does lot look as if a part number is on it.  

 

Please let me know if you have any questions!

Wonderful, thank you for the news, Brent! I'll mention this to my dealer hoping they will contact GM to fix my truck too. Please keep us updated if you observe any further issues.

Got the same part as above and it seems to be working so far. 

Great news, thank you for the update Will!

Just talked to my dealear, they don't have any update yet from GM Canada.

Where did you get the part, Will? I wonder if I could order it online and have it installed by my dealer.

    • I would have to read back to get a better picture in my mind of some of the other comments and what they were using for a driving scenario they based the fuel mileage off of. That is why the fuel mileage conversation is extremely difficult to make fair comparisons from. If I was to be living in town and only driving around town, light to light and some longer stretches that doesn't have a light every block, and the usual stop at a grocery store and the bank and so on and so forth, my fuel mileage even during the summer time would be so bad with my truck I don't even want to know how bad it would be !. Then add in winter time and idling to warm it up to clear the windows and driving through snowy streets etc, large heavy trucks with gas engines have NEVER been worth crap for fuel mileage and why some little pot licker of a car with wheelbarrow tires and a 1300 cc four cylinder non turbo engine was the ticket to using a mere fraction of the fuel over a full size pickup.    By the way my truck has the 34" tires as its a HC but not the BFG KO3 tires ( that was an option for my truck but the sales guy couldn't figure out what the tires actually were so that never got on the order until it was too late to change the truck order ). So what fuel mileage your getting actually sounds good for "town driving" and with my truck when I go to town the fuel mileage keeps increasing as I get closer to town because it takes quite a while to get the driveline oils warmed up ( and why it always shows better fuel mileage on the return trip from town because its already warmed up ) but once I am in town that fuel mileage average just keeps dropping the more I mess around town and then has to recover back to something reasonable again by the time I get home for an over all average.    I'd be curious what your sticker says for the factory weight of your truck, mine is close around that 7700 lb due to the options it has. But anyway the long and short is, vehicle weight, higher rolling resistance heavy tires and a hefty driveline and a relatively large gas engine make for crap fuel mileage in stop and go scenarios, all one can do is drive it easy off the line at each stop and as my dad had said over the years, drive like a raw egg is under your foot and that's the best one can do. Years back with a carbed engine and if the carb was getting a bit out of tune etc as would the ignition system, the fuel mileage on pickups with larger engines was just awful compared to what your getting. We pay the fuel price penalty for driving HD trucks over some little vehicle, that is the reality. 
    • We had two Toyota’s with that engine in the mid 80s. We had 50 gallon fuel tanks, a toolbox full of tools, an air compressor and assorted parts for our equipment. We beat those up and down pipeline ROWs until we started buying diesel trucks. Then they became parts runners and first vehicles for our teenagers first cars. Our shop Forman wrecked them both two years apart when we hired him out of high school as an apprentice. Good thing he’s an excellent mechanic. It took awhile before he could be called a good driver.
    • I have a 2025 GMC Canyon Denali.   On a trip recently the engine failed.  The dealership diagnosed a bent valve and says there is a service bulletin that indicates to 'relace the engine'.  The truck only has about 14K miles and is under warranty.   The failure occurred 5/11/2026.   So far I have worked with GM Customer Assistance and Roadside Assistance.  Evidently no engines are available and nobody will offer a date when a new one will be.   Coming up on two months with no repair or timeline and no loaner from the dealership.   GMC Customer Assistance is 'ghosting' me and keeps closing the cases I've opened with no resolution.   Hoping someone can help me on how to escalate this issue.
