Yeah, I agree. I don't think my issue is mechanical at all and apparently neither does the engineer. The service advisor gave me and update yesterday afternoon. He said the engineer wants to replace all the electrical components and sensors and have the originals sent in for testing. The parts are on order and should be in next week. The idea behind this digital assist steering is cool, but I'm not sure that the complexity is worth it. To many possible points of failure...

So my 2016 had the service power steering msg show up twice one day last week. brought it to the dealer today and they said they had to contact an Engineer to find out what should be done. I have a copy of PIE0430. My truck doesn't appear to be leaking from the steering gear and I do not notice excessive lash. When the msg comes on the steering feels like its over assisted (easy to steer). When I restart the truck and there's no msg the steering feels fine again. Anyone had these symptoms with theirs?

doesn't work with the 6 speeds either...

I have a very pronounced decel clunk most noticeable in 2nd and 3rd gear. GM says its normal for your new truck to clunk like it has a bad U-joint. I believe its related to the TCM program. I think that it could be tuned out but could adversely affect fuel mileage. Because of this we will most likely not see an update from GM no matter how much we complain! I seems that plenty of the 8 speeds have this same characteristic. Sad, very sad!

I gave them a copy of the PI and they ordered the parts. It was pretty painless. They also ordered the headlight bulbs for that update as well

Had the update done yesterday and the seat feels very solid now. The tech that did the work said the new laterial supports should work well.
