hello, there is nothing wrong with the cts, I have a 2006 I have owned it for 1 year and 7 months! the problem I did run into were bad vibrations as a result of the tires! there is a bulletin out on the good year tires they put on the cts! I have had the tires replaced a couple of times after arguing with cadillac and the dealership for about a month or so I requested a different brand tire other than good year! I had them put michelin tires on and the ride is fantastic again like when I bought it! The good year tires have a defect excessive road force! they do not high speed balance and they have flat spots on them! usually a tire has a flat spot from sitting all night these tires do not take shape until they are warmed up and then they just get worse and do not shape up at all! the tires are bad ! they will effect the entire performance of the car any car for that matter! good year tires are bad!!!!!!!!

use a road force balancing machine as well.....that seems to get rid of the problem....most techs dont know how to properly use a machine or balance a tire today it seems..particular at a dealership....hunter makes a good machine for this I beleive...it may cost you more for this type..but its worth it

Cadillac rep came in town Friday and drove car for himself. They are keeping it over the weekend because they say something is causing the engine to mis. Doesn't sound like a tire problem.

I don't know if you've resolved this problem yet, but it sounds to me like you have a lock-up problem. The speeds at which you're describing your vibration is when the torque converter clutch engages, aka 'lock-up'. A lock up clutch can shutter/chatter on engagement--this problem is easily and often misdiagnosed as an engine misfire. There is a GM service bulletin on this exact problem for your car. Most of the time it is fixed by a simple reprogramming of the computer, if that does not fix it then step 2 is a new torque converter. Hope this helps, I can get the bulletin # if you need it.

Problem solved. The rep finally came in and while I had my car in I told them I also needed an oil change too (I was about 2,000 over normal change time). Dealer called me back and said I had almost no oil in my car (kind of accusatory). I told them On Star told me I had oil life left and showed them the print outs they sent and I've had my car in several times for the shutter problem since my last oil change. They agreed to replace my entire engine under warranty and the shutter problem is gone with the new engine. They also charged me for the oil change (you'd think you'd get oil with a new engine).

Oil life and oil level in the crankcase are two different things. The oil monitor may say that there is oil life left even though there is no oil in the engine. You should check the oil level when you fill up the fuel tank or on some other regular basis.

the original goodyears lasted 30k. currently my cts has 65k with original brake pads, something is not right there.

Please post Service Bulletin you referred to in item 31...about programming the computer or replacing the torque converter.
I have a 2008 CTS with 1200 miles and I experience a vibration from 40 through 65 MPH, it is worse when on an incline (slight or steep) it is worse at 40-42 MPH. Vehicle also vibrates in reverse when backing out of my garage (slight downward slope) with basically no accelerator applied.
Anyone having this problem please reply.
