Besides THESE issues I mentioned, I also had to have my 05' sport rear end axle lub changed (heavier gear oil w\additive as per dealer). There was a bulletin by Cadillac to perform this service when noise or griding was heard when backing up (my case, through barely audible and original thought was front wheel rub on reverse turning). It quietened it down to ZERO noise...good to go!Hi all,
Considering to buy a 2005/2006 CTS 3.6L automatic. Are there any known problems I need to pay attention to?
