Several of the problems I had or am still having the dealer tells me they haven't seen that before. Think this is just a pat answer.

I have a 2008 DTS that also has the humming/grinding/rubbing noise on occasion. I, at this point can not duplicate it at will. It does it more often on hard throttle, but can happen just in normal driving. Of course it can not be diagnosed at dealer, when it doesn't happen all the time. Please post results, if cause is found by anyone.I will do the same, if I find the cause.

i'm also the owner of a 2008 dts with a high pitched humming noise between 15 - 30 mph, you step on the gas to hear it and as soon as you let off it goes away, very annoying, also if anyone out there has a problem at about 45 mph, it feels like it won't shift and gets somewhat sluggish, it's a weird problem, also very annoying when you're cruising just around 45 to 55, i'm sure telling the dealer will be a waste of time

bendo42: I have the exact same problem. Although my noise does go away completely if shifted into park or neutral. The noise doesn't happen if the A/C is off however. Have you found a solution yet?

Re: bendo42: I have not heard the noise this winter. However I have not driven the car very far, only short trips. I am wondering if air vents are part of the problem, it happens more during A/C temperature changes. It is also possible if it's the cable as mentioned above, it has moved. No real solution here. See what summer brings.

Sometimes come on immediately, sometimes won't come on for days. New fluid and filters in tranny. synthetic and Lucas. Before I drop the cradle, any help is greatly appreciated!! dj8815yahoo.com

Not sure if you are still active in this discussion but thought I would ask anyway - By chance do you happen to know the TSB for this service issue? I have a 2006 with many issues that the dealer cant seem to fix but this is one that I need to solve. At highway speeds (60-70) i get i high pitched vibration or humming noise that sounds like its coming from the windshield and I believe it is the shift cable. My mechanic is wiling to take a look at it but asked if I had the TSB #
Any additional info is greatly appreciated

I no longer know what the TSB is. I found the windshield noise by excess speed one day. They resealed a part of the windshield and it stopped. For a Cadillac these cars are not as flawless as I would expect. Good luck with the service.

I appreciate the response but do not believe it to be a windshield issue with my car. The intermittent humming i am getting I believe is from a shift cable inside the engine compartment and whats strange is that I can go weeks with out hearing it then all of a sudden its a daily thing when i am at highway speeds. If anyone happens to know more, TSB (Tech Service Bulletin) or how to address this cable, please let me know
