    2006-2009 DTS Common Problems

    Hello all, I have a 2000 Deville and I am considering a 2006-2009 DTS. I was wondering what the common problems on these cars are. Do they have the same issues as the 2000-2005 Deviile's? My car has had basically every problem that is common on those cars..just want to see what I would be getting myself into with one of these DTS's..Thanks for your time fellow Cadillac brethren....

    I originally posted this in the DTS forum but apparently no one over there cares to answer me...I figured I would try here, sorry for the double post but It seems like the most knowledgeable people hang out in this forum and I really would like to know what im getting myself into..Thanks

    I'm not entirely sure if they've had enough road time to tell. So far, no. I've only ever heard of ONE with HG issues. That's it.

    Most of the earlier troubles seem to be fixed, though the model's not old enough to tell for sure. Other than the '93 Northstar technology was a little bit outdated in 2005-2010, it should be fine.

    What would've been great; a 6T70/75 equipped with a FWD Northstar, and several updates to improve performance (though as a FWD, 300 hp is adequate), but the model and the engine were both planned for its extinction.

    They could have at least kept the RWD Northstar; and make a DI version out of it, bolted with a 6L80. N/A ~360 hp / ~350 lb*ft ? Not bad for a luxury V8 RWD, and probably will still get decent MPG just like the old Northstars did.
