We own a 2003 Cts Cadillac with 40,000 miles and still under warranty. I have had the car in for repair several times for the same reason. The car shakes at certain speeds. Eg. 47, 59,65,69, and 75 miles per hour. The wheel actually shakes in my hands. It is a problem with the transmission. Cadillac stated it was characteristic of the 2003 Cts. Maybe an escort but not a Cadillac. They offered to extend the warranty on the transmission to 100,000 miles. Whoopie. I now must drive a car that I feel is dangerous to drive. I really believe the transmission will totally fail and soon. It gets worse and worse. Thanks for viewing this letter.

Vehicle lost power when the consumer hit the brakes. The transmission jolts and then the engine shuts off. It has been to the dealer 6 times since January. The dealer tried something different every time she took it in. Manufacturer said she could have a new vehicle if she paid for it. She wanted to get rid of the vehicle. The check engine light illuminated.

There needs to be an in-depth investigation regarding the number of Cts and Cts-V rear differentials that have been replaced. I have now been through 2 personally, and an online poll of 65 Cts-V owners showed this: 26% have had 1 replacement, 5% have had 2 or more replaced, and 8% have had 3 or more replaced. The link for this poll is: cadillacforums.com/forums/showthread.php?P=305662&posted=1#post305662. Please contact me regarding any information learned. Thank you.!

Loud high pitch howling noise heard from inside at approximately 40 mph and over. The first trip to the dealer I was told it was a wind noise. The second time at the dealer's I was told it is a normal characteristic of the 2003 Cts.
