Same issue. Purchased truck October 28. Hooked up trailer for the first time on November 28 after 1400 miles for a test drive with the trailer and experienced the same error almost immediately. I am glad I did that test run before my trip.
 

This has been a horrible experience. I could not get an appointment locally. The only dealership that would see me is the dealership where I bought the truck, which is 3 hours away (one way). We woke up at 3am to get to the dealer at 7am to diagnose the issue and tell me that there is nothing they can do and call GM. This is what the paperwork says “SCAN FOUND C159C TRAILER BRAKE CONTROLLER SWITCH UNKNOWN CAUSE ,,, ENGINEERING AWARE OF PROBLEM AND WORKING ON FIX TSI PIT5948A” That was an entire day wasted. A day I should have been camping.

 

Another pain, is that in trying to diagnose the issue on my trailer side (before I found this post) I replaced the 7-pin plug on my 1 year old trailer which I now know was totally unnecessary.

 

Opened a case with GM which has been escalated but have not talked to the next person yet. Also opened a case with BBB and GM called me about that case yesterday but I was unable to answer my phone. I will keep checking this post for updates and I will post as well.

 

 Like many of you have said, it is sad that GM sells these trucks with this known issue. We bought this truck specifically for towing my RV. Now every day I have this truck is another day I cannot use my RV, which I use for business trips, doctors appointments, and vacation trips. Just had to cancel a trip this week, and I have two trips lined up in early January and beyond. On top of that, this is our only vehicle.

 

My wife has also contacted consumer reports.

 

Anybody aware of any class action law suits?

 

Glad to posted to BBB, I also posted to NHTSA. I’ve not heard back. I’m not aware of a class action yet. Sounds like we use our RVs for similar uses making this a critical issue for us. I’m in OK and had a similar dealer experience and GM is supposed to contact me every 4 days with updates. My buy back request is pending.

Dont waste your energy filing anything with the BBB, their only function is to avert your attention away from people with the ability to actually solve problems. Its a trap. 

I know there are a lot of these cases out there but one of the biggest problems with trailers is the piss poor quality of the wiring and the components. Its kind of like trying to connect an 8 track player to your I-phone. 

A lot of the problem is trying to make a sophisticated, sensitive electronic system work with poorly built, ancient practices(RV's)

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's understandable that problems might come. 

 

GM should have communicated this directly to their dealers; especially when it's regarding a core function of the most popular vehicle in the lineup and its very popular derivatives. I spoke to three dealers and all three claimed to have no idea what I was talking about. I believe them. 

 

Instead the trucks found their way onto sales invoices with no parties involved aware the problem that had just been created for the customer. I feel for those of you that have had to cancel vacations or now can't complete important work. 

 

In my opinion, anyone approaching GM (not dealership) in a predicament because of this issue should have a buyback waiting for them after a dealership has confirmed the issue. Sure it's going to cost sales and is most likely not good for the bottom line but I think demonstrating they are willing to leave a paying customer hanging because of a known issue (i.e. preexisted the truck and the deal) can't be good for brand confidence.

Well said!! I couldn't agree more!!

It's just sad that in this crazy world we are living, big business no longer care about their customers. It seems making sales and lining their pockets is more important. 

We need to get as much information out to potential buyers as we can, so they don't have to deal with what we are currently dealing with. Again, that should be done by GM, not their customers. Nonetheless it needs to be put out to the public.

Out of curiosity, does anyone have a '22 that does not have the brake controller issue? 

I didn't get the brake controller. Picked up 22.5 Silverado off the lot as equipped cause it took 4-6 months to order. Barely any GM trucks  on lots here in Ontario. I just popped in my Curt Echo Bluetooth brake controller. It works off my phone. Plug and play, swap vehicles and take it with you. It just uses the 12 volt supply from hitch plug...owes nothing to the vehicle you drive. Just need 12 volt power supply (mine was there already). I used it on last trailer with no issues.

I like the idea of the wireless brake controller. Thanks for the heads up, I can look into that. The Echo uses an accelerometer to apply the brake.

 

Kind of funny how a smart phone can interface with trailer brakes and a $60k truck cannot.

Ford has way way more issues than GM. I've worked at both dealerships as a technician. GM has issues, but Ford problems are monumental. People still love them. Just as an example of the difference in FOWARD and GM...  we regularly had to tow new Fords off the car carrier. Some came from factory with AC compressor not installed, but hoses and wiring there. How about 3 sets of brakes on an F150 in 60k miles?  my insurance agent said GM is cheaper to insure because it's much harder to steal than Ford. GM tech with On star make it risky to take.

On my new GM, i'm simply using the Curt Echo smart wireless brake controller. Works real slick, plug and play. You're phone is the controller.

There will be a software update and patch.

Does your truck have the problematic trailer brakes?  Just curious if the Curt system will work if the truck has the integrated trailer brake system.  I've tried a couple of wired external brake systems and they won't work because of the integrated system.

I happened to notice this when looking through inventory on the Chevy site:

This note is on the vast majority of trucks listed but I can't seem to find any information on it. I also found the same message when looking at inventory directly on the dealer sites. Does anyone know what's behind this? Is it possible this is related to this thread?

Same issue on my truck 2022 ZR2.  Same "No resolution GM is working on a fix" response from dealer.  Started a claim with GM waiting for response.  I NEED to tow regularly with this truck, tractor or travel trailer 6-8k lbs trailer multiple times a week. I think we can all agree this isn't safe.  I just want the truck to work.  I'd be happy if they found me another one, but this downtime is killing me.  Before the problem was diagnosed, we spent a bunch of time testing on other trailers and other trucks.  Can anyone tell me what the benefit of posting the issue to NHTSA?  The dealer doesn't have anything to loan me and I just had to pay to have the travel trailer transported to my property.  I'm losing faith here as the truck also makes a strange intermittent knock noise while warming up in the morning too.  This situation with the trailer brakes is going to cause accidents plain and simple.

I have the integrated trailer brake system and I have the curt system and it works great. Uses the power pin to power it so the truck doesn’t think it needs the brake controller.

Hey GM! Almost end of the year. WHERE'S the integrated brake fix? Fix what's already out there before building new ones. Recall for driving lights coming in January that's a safety issue. Get the lead out.

    • There are probably a few threads talking about fuel mileage but this one seemed to fit the stats I have seen based on my typical local driven route but with different outcomes based on different seasons/temperatures. I have a few hundred pounds of items that consistently ride on the truck at all times such as a bak flip cover, rubber bed mat, tools and extra fuel so I would be something over 8100 lb without me in the truck. All these examples are based on a 100 mile round trip to a town plus running around town so maybe 110 to 120 miles in total for a trip. Using regular fuel and I assume it always has some ethanol in it but don't know the percentage they blend in. Also speed wise I am going at 62 mph and non aggressive driving although less speed yet if its crappy winter condition roads. I am going by an initial reset of the computer generated fuel use numbers averaged over a couple of thousand miles or so for each weather/season so they may be more optimistic then actual hand calculated numbers. Basically this is painting a picture of doing the same drive but seasonal conditions and temperature being the major variable to the end result. Oh and although I am in Alberta Canada, I am converting it to miles per US gallon so there is no confusion.    So winter time it gets cold here, no real surprise there and the roads can be clear at times but also often have packed rough snow or are are driving through loose snow ( they do a poor job of plowing the highways ) and yes this includes the extra idle engine time due to trying not to freeze ones butt off. 12.7 mpg is what I was getting during the winter months on average.    Then during the spring when it was around the freezing point and the highways are clear of snow, I was getting around 14.25 mpg.   Summer time, I have been getting around 15.15 on average but certainly some of the trips showed quite a bit better fuel mileage, so much depended on how much or little I had driven around town and number of engine restarts after sitting for a while at each location. But stating a best fuel mileage trip to town pretending that is what the truck gets on average is fooling ones self for sure !.      As I said in a different post, I had driven a 645 mile trip over a couple of days stint to a different destination then these other daily to town examples above, and was done during the summer with nice weather and not bucking a head wind, also keeping at 62 mph and its a rolling landscape type highway drive ( this isn't southern Alberta or Saskatchewan flat lands ) Hand calculated fuel mileage in this case though and it came out to 17.65
