Replying to: junet (Nov 12, 2008 8:18 am) Mine is an '06 CTS with the sport package option including 18" wheels and different Bridgestone tires. (Just under 16k miles and the tires do not have excessive wear). I notice the "rubbing" noise when leaving home in the morning and when pulling into the parking spot at work. I actually believe it might, and I repeat the word "might", be caused by the inboard rear tire (i.e. when turning to the right; the right rear tire) rubbing on the epoxy-type painted surface of the parking garage floor of the building I work in. Then when i get to work - they recently re-sealed the whole parking lot with blacktop sealant - I think that's causing the rubber tire to make that rubbing noise at slow speeds over the epoxy sealant when turning sharply into a parking space. Sounds strange, but I believe - or at least I want to believe - that is the cause. The CTS has a very tight turning radius compared to most vehicles (which is a really convenient thing). When turning sharply at low speeds, that means the inside rear tire is actually turning somewhat on its axis rather than just rolling forward over the road surface. Hence, this could be the cause, or at least "a" cause, for the rubbing noise, because the tire rubber is actually being rubbed against the surface its on with these tight turns. Very few vehicles of this size have the tight turning radius the CTS has (not sure if the '08 and newer CTS' have the same tight turning radius). Rob

Replying to: junet (Nov 16, 2009 8:00 am) Do you have you copy of the the dealer service form/receipt from when you had the fluid added 6 months ago? I am curious if they wrote in what fluid they added. The more details I have, the more I can just tell my dealer "do this". I'm assuming it'll be a warranty job... Rob

Replying to: junet (Nov 16, 2009 11:52 am) If you are able to find the work order in your files it would be helpful to know what they wrote down that they did (although the fact that it only lasted 6 months is discouraging). If the guy at the dealer knew what it was then it's apparently a relatively common issue with the pre-'08 CTS model. Thank you. Rob |

Replying to: junet (Nov 16, 2009 8:00 am) the rear difs were a weak area in the early model CTS's....and carried over into the 06-07 MY Pontiac Solstices...which use the same rear diff.......08 and beyond seem to correct the problem.....Im betting it is the rear differential.....

Replying to: pao (Nov 18, 2009 5:43 am) So, we added doing the rear end fix job to the list. He said it works on 8 out of 10 vehicles, and if not, then the rear diff. needs to be replaced (all warranty). Obviously a known issue, and at least they own up to it and will address it under warranty. Driving a brand new DTS loaner car in the interim...
