Hi all. Add me to the trailer brake issue list. I just bought a 2022 1500 rst in Topeka, KS, to haul my camper with. Right out of the box, had to tow my camper 430 miles at reduced speed so I could stop safely. Over this whole trip The trailer brakes operated about 10% of the time. The other 90 I kept geeting the brakes disabled service message. Sometimes they would reset after restarting truck sometimes not.  I had my son hook up to my camper with his truck and towed it, no issues. Hooked mine back on it and second time I used my brakes they were disabled.   I need a vehicle that will tow my camper, this truck is useless to me. How the hell does GM get by with this. Consumer's should be informed about these issues before buying these paperweights.

Update: stopped by the local GM dealer on 1/31/22. They pulled the same code most of you guys are getting, c159c.  Also did the driveway test...hooked up to camper.... using the slide controller it would occasionally flash a disable message but would clear itself. When using the brake peddle, somewhere between one and six presses I would get the disabled message and trailer brakes would shut down, until I shut off and restarted the truck.

My philosophy is never not to judge by the mistake itself but rather what's done to resolve it. There's something wrong with these trucks' ability to control a trailer. With such a complex machine, it

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 1

Hi Ted, thanks for sharing this!

Can you please let us know if the brake controller switch replacement procedure for Silverado Trail Boss is the same as for Sierra Elevation? Daniel Murphy posted the steps for Sierra here.

Thank you!

Everything In Daniel Murphy's post looks exactly the same as the TrailBoss I have.  The only thing that was slightly tricky was once you have all the screws out of the heater controls trim, pulled carefully on the right side of the heater control trim to release the clips securing it to the carrier/dash behind it.  Still had resistance on left upper heater control trim.  I had to carefully pull out very slightly on the information trim just enough to remove the heater control assembly, by sliding it downward from under the radio/upper dash trim.  Then I was able to swap out the trailer brake control switch.   Just an FYI  I called by dealer parts dept with the part number from the switch I removed, and was told that that part was superseded/updated to the new part number.  I have a hunch the old part number was pre-refresh stock/parts and the refresh software is not compatible.

Bulletin PIT5948 only talks about model year 2022 but let me assure you I have the problem on my 2020.  More often than not the trailer disconnects after the brakes are successfully applied.  Unfortunately, it takes 20 seconds or so to reconnect all the while you are left with no trailer brakes.  Trailer has no connection issues when pulled with my older 2000 Silverado that is equipped with an add-on controller.

I tested just connections to trailer.  No issues or failures.  Plan on road testing this week!!! Previously it would fail quickly.  So far so good!!!

Thanks for the info Daniel, going to call my dealership to see if I can get then to replace this and if not I may end up doing it myself.

Thank you very much Daniel. I followed your directions and pictures and they were a great help for me to switch out my controller. I’m happy to report that at this point it seems to be working fine.  I Can’t understand why GM isn’t fixing this over about a $35 controller.148F4C3E-5EC6-4465-B28F-EC9B55B6DB11.jpeg.8e8c00fba8f84d7f191fdc7990d1806d.jpeg

Good job bell75! Did you have to reprogram the new controller, or it worked out of the box?

You used the same part #84488395, right?

Just got my switch in and installed today in my 2022 ZR2 and it seems to be working correctly. I ended up getting mine from amazon. Took the trailer around the block and no more message about the brakes being disabled and all the functions are working.

Called my dealer last week and they replaced my brake controller. They tested it in the shop and it seems to work, but I'll have to wait until end of March to validate it is working with my trailer. Hope it is fixed, I'll keep you posted!

Just found this article, somebody could have died because of the same issue: https://www.wfmynews2.com/article/news/local/outreach/call-for-action/gmc-truck-owner-says-trailer-brakes-failed-nearly-causing-an-accident/83-e4bbd375-3c35-4e02-9af0-13e6ce013471

 

Somebody will be gravely injured or die and there is still no official fix from GM to a problem they are aware of for half a year now! Very disappointing...

My dealer called me Friday afternoon saying that they had an updated  switch that they were going to put in my truck that is supposed to fix the issue. I'm taking it in on 24th to have it done so I'll keep you posted on whether it works or not.

Thank you @daniel murphy

 

With your tutorial I was able to replace this switch in about 20 minutes.  Local dealer had one in stock (New P/N 84488395) for 20$.  Towed about 100 miles yesterday and today without issue.  No more alert message/trailer brakes disabled and Braking is much stronger on the trailer now.  I had to back the gain down to 6 to prevent tires from dragging.

      MPG at 600 miles

      100% agree, there are a lot of variables. I definitely do not drive I’ve like a grandpa but also don’t drive like I stole it. Truck is currently in the shop so I’ll have to get weight later. The price for driving it doesn’t bother me. My precious was a 6.2l so the cost between the two is a wash.

      summer road trips in the 2026 2500HD

      By c4racer2 · Posted

      that is pretty awesome MPG there!  I think so far one observation is these trucks do way better on MPG under 65mph vs 70+ and they really suffer at 75+   I noticed on the stretches into NE on 76 and 80 which is posted 75MPH and I was doing 82 I was getting more like 13.

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      By newdude · Posted

      No ETA is available for that engine at the moment in the GM system.   I would start at the dealer.  Try and talk to the parts manager or service manager and see if they can start a CX Connect case and get an ETA from GM on when engines may be available.  If they just check Parts Workbench and say "no eta", they aren't trying hard enough.  They need to do a CX Connect and chat with DPAC to find the ETA.

      MPG at 600 miles

      By Chuck FB · Posted

      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.
