Differential Unit problems of the 2008 Chevrolet Avalanche

1-takata recall 2- rear differential- I had to completely replace the rear differential at 153,000 miles. I have seen a lot of the same problem reported on different online forums. There should be a recall on this. It cost me over $3,000. It had many broken parts inside of it. It could have locked up the rear wheels and caused a very unsafe condition. Thank you.
