Fellow Members, I seek hearing from anyone with a similar problem that they have resolved! My XLR has developed a leak in the exhaust system, according to the code reader. My local Cadillac Dealer who has displayed limited knowledge of this Model has diagnosed it as the cross over tube leaking by using a smoke test! The estimate for repair is 7,500.00! I have investigated this recall. A Bulletin dated Aug 13, 2010 calls for a replacement procedure. As far as I can see in my WORKBENCH History this was never done! The time period for this expired 11/19/2011 at 80005 miles. My 2004 has less than 54,000 miles but it is 2021! Has anyone filed a class action suit or had any experience with this repair?
