I've been going through the process to qualify for a buyback via the "lemon" laws in Utah due to the faulty trailer brake controller. A GM field service engineer was dispatched to look at my truck a couple weeks ago to no avail. That was the fourth attempt at repairing the issue, thus qualifying me for a buyback according to Utah law. Funny enough, as soon as GM got wind that I was pursuing arbitration via the BBB, they called me the following day saying they magically have a fix. When pressed, however, they called back and asked me what I want to do, and they are now coming up with a buyback offer. I have no idea what to believe from GM. If they really have a fix, I'm the only one who's been told about it at this point, apparently (at least I haven't read about a fix anywhere else). I have my doubts since GM said they'd put together a buyback offer the day after telling me there's a fix. I'm not willing to go the 3rd party/aftermarket route with the trailer brake controller.
