Hello! Welcome to justanswer!


Theres a TSB on a lower end oil leak thats a really big job. Make sure its not leaking oil or that the problem is not present on the vehicle you are looking at. Also theres a recall for a bad power steering pressure hose so make sure thats done. Futhermore theres a recall for a bad onstar module so make sure thats been done as well.

We heard about the Northstar engine bolts backing out causing overheating, is this true in the DTS model? How worthy and dependable is this engine and have you yourself had experience with bad Northstar 4.6 engines? This 2006 has only 36,000 miles.

I have repaired this problem and I believe they solved it on the 06 but I would be sure to get an extended warranty on the engine as any internal engine problem is extremely hard to fix if it does come up and is very labor intensive.
