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.

Thanks for the update Dakota Cole. I did some searching and found that a law firm is investigating. They have a good write up. https://lemberglaw.com/chevrolet-silverado-1500-faulty-trailer-brake-controller/

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?
