I am going to guess that they don’t have anymore parts left. When I had mine done about 4 months ago, they authorized a complete dash replacement, but the dealer couldn’t find any parts. We found one in Europe, but they knew the high demand and were asking $2000 for it plus $500 freight! I went to my local mechanic and we bought a dash out of a wreck, but it was broken in a couple of places. We found a local car upholstery shop, and they recovered my dash with a very nice padded leather look material.
I had my GC for a little over a year. I had to do a water pump, drive shaft, dash and at the end, the transmission was slipping and the air suspension was on its way out. Too much for me!
I bought a 2017 Audi Q7, which is a whole other step up in refinement. It can also tow up to 7700 lbs.
