#9 of 10 2008 DTS grinding/rubbing/ noise by hook35 Aug 07, 2009 (11:27 am)
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.

Replying to: bob247 (Jul 05, 2009 3:32 pm) 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
