Just dropped my 4xe off at the dealer this morning. In addition to all of the already well-documents RRTs 21-122 through 127 and 137, there was a new one that showed up: 21-170. I couldn't find any information on the interweb about it so I called back to the service advisor. He said it is related to re-torqueing the the nuts on the lower ball joints, so I guess this seemingly well-known problem is now official.
