Hello everyone,

I have recently acquired a 2022 Silverado LT Trail Boss and since the first time I connected my trailer (a 2020 Flagstaff E-Pro 20BHS) I have this buggy display on the camera.

The brake controller randomly stops working, but the camera is consistently buggy. I contacted the dealer, they investigated the issue and concluded the brake controller is faulty. They cleared the brake controller error codes and updated the camera software, but the display is still buggy every time I connect the trailer. I have the buggy display only in camera mode, it looks ok in other menus. Waiting for the dealer to replace the brake controller, but I feel the camera issues will not be fixed this way. I checked all connections that I could access under the truck and they look ok.

Did anybody else experience this issues? Any help or advice that I could use are greatly appreciated! Thank you!

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

I had an appointment yesterday and the dealer tested the issue with a new brake controller, but the same error codes have been displayed (C159C). It looks like there is a software issue. Looks like GM published a technical bulletin (PIT5948A), but I can't find any details on it.

I just hope GM will find and fix the issues soon, I bought the truck for towing and I can't use it. :(

Hey Drafil!

 

I'm in the same boat as you with the C159C code. I Haven't been able to get any resolution on it either. I have the bulletin PIT5948A, I can post it if you want. I have a case opened with GM Corporate as the dealership isn't very helpful. If they are unable to fix it sooner than later I'm going to attempt to go Lemon Law on it as its unacceptable for a pickup truck to not be able to tow.

Hi Shield1984,

Thank you for your comments! Yes please, I would like to have more details on bulletin PIT5948A.

I will also open a case with GM this week, I have to get more info on the procedure. Any hints on this topic would also be very appreciated.

I absolutely agree with you on the Lemon Law! Although we don't have the Lemon Law in Canada, there is an equivalent that can ultimately force the manufacturer to buy back the truck. I absolutely love this truck, but I bought it for the towing capabilities, so if it cannot accomplish its main purpose, it is useless for me!

Thank you!

I'm having the exact same issue sans the camera issue.  Same technical bulletin given to me by the dealer and C159C code. My dealer gave me the information, I called GM to ensure I opened a case - I bought my 2022 refresh 3.0 RST to tow a small camper for my family and I.

 

The brakes work fine for a few minutes - then they throw a message onto my info panel "Trailer Brakes Disabled Service Required".

 

I thought it was my trailer, however had my neighbors tow it with their Ram and Ford, neither had any issue.

 

I called my dealer, they informed me it could be the technical bulletin/code above, but to bring it in - they confirmed my truck was falling under it.

 

They did wire an aftermarket controller into it on Friday, which I will test this afternoon (was running around all weekend with kids and events). I also called customer service this AM to get a case number (albeit they cannot find the technical bulletin on their side) - but the most frustrating part of this the lack of transparency and estimated timeline to fix.

 

I found this truck in transit to my dealer because it had the package with the brake controller and cameras in the mirrors that will shoot back either side when the turn signal is on, my wife booked a few camp sites for us this fall (including this coming weekend) - if the external controller doesn't work, we will need to cancel those, and regardless, the brake controller with wires up to my center console is not going to be an acceptable long-term solution.

 

I wish:

 

1) I was told about this during my purchase - I doubt my salesman knew of the issue - I put my wife, myself, and other motorists in danger by driving he rest of the way home from the trailer dealership, but took it easy, however when I did need to stop - the brake smell was obvious.

 

2) I could find more transparency online regarding the PIT5948A/C159C online, this is one of the only places I could find a post on it.

 

If this external brake controller doesn't work, I'll video the issue in my driveway and post on YouTube to show you the issues I'm having.

 

edit/update - The external brake controller did not work.  I've photo the message I receive when trying to use the integrated controller.

have you tried hooking to a different trailer, some how you are getting a feed back on the trailer camera wires

Hi Silveradosid,

No, I have not, but my trailer brakes worked perfectly with the aftermarket brake controller (Primus IQ 90160) installed on my previous vehicle.

I'm dropping my truck off at dealer overnight, they are going to try another external brake controller and this time test it on an employee's trailer.

 

This all sucks b/c 1) they are 45 minutes away. 2) I don't have the time to take it during the day b/c of meetings and 3) I need to find rides home tonight and there tomorrow night - I leave for a work trip on Wednesday AM, returning Friday afternoon before our scheduled trip.  I guess I'll need to test it Tuesday night before I leave to determine if we can even go on our trip at this point.

Unfortunately, I am having the same problem.  I have a camping trip booked this weekend as well and I guess my $60k Chevy Silverado that I purchased 2 weeks ago is going to put an end to that.  How does this happen?

I'm with you.  Chevy will get the wrath of my wife.  It's just disappointing, I'm in the same boat. I said 3 months ago to my wife "I'm going to keep my 16 Frontier" for 3 more years then go Electric."  Then 30 days later she said "lets get a camper, the kids will love it".  I sold the Frontier, researched Ford v. Chevy v. Toyota (not Ram, I think they are ugly as hell) and narrowed it to the F150 Hybrid or the 3.0 Duramax.  I couldn't even see a Hybrid for 2-4 months based on convos with dealers so test drove the 3.0 with the refresh and loved it - Now I'm sitting with a truck that I can't do anything more with vs. my 2016 Frontier...

So it looks this issue is not isolated. Let's keep each others updated on the subject so that if one of us gets to fix the issue, the others could also benefit quickly.

      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.

      Slate Electric Truck

      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.

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

      By William Aldrich · Posted

      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.
