I have recently purchased a 2006 CTS 3.6L and have been experiencing vibration in the steering wheel once speeds of 50-60 mph are reached.

The car which has been taken to the dealer on four seperate occasions has chaged the wheels from the factory installed Goodyear to Bridgestone to Michiline and then completed a alignment and then a load force balance.

The problem, although not as pronounced, still exists and think although the wheels have helped, is only masking the real problem...which has yet to be determined.

Has anyone experiences this in the past and what resolution if any exists. The car is a great piece of engineering/styling and once this item is resolved will be quite happy.

:welcome: :yup: Welcome to the Forum BlueTooth:bouncy: :D

You seemed to have covered most of the causes for the vibration. I assume that a tire specialist is doing the checking and not your dealer service dept. Are they using the advanced Hunter balancing equipment? How about your rotors..they too are a part of your rolling mass. You mentioned you changed to several tires..how about rims? A warped or bent rim would cause problems.

Dealer did laod force balance on Hunter machine at external shop.

Dealer did measure rims and said all was OK.

Still in a dilemma.

Thanks for your reply.

I know it CAN... as you said it is part of the rotating mass.

Did they also check the rear wheels? at 50-60 even out of balanced rear wheels can cause vibrations in your steering wheel!

One of the disadvantages of the Hunter machines is they only balance the tire and rim. They use to balance the whole assembly while on the car. This also took into account your rotors. Move ahead two, slide back one.:(

Have the same problem on my '05 despite several attempts to balance, etc. I think it's a flaw in the CTS drivetrain. Keep taking it back in and document everything.........you'll need it down the road........believe me.

Try switching the front wheels to the back to see if the vibration moves to the rear, If it does you most likely have a rim issue. If the vibration stays up front, then you could have a bad wheel hub or some front suspension issue. I think if it were a rotor issue it would be even worse when you apply the brakes.Good Luck and Welcome to the forum.

We have all complained about this on the CTS. I ve done it all, and in the end it just wasted trips to the dealer. I had a loaner for the day, it diddnt have the sport package but it had the 3.6L and guess what it vibrated! I think this is the sport feel but i really would forgo it if i could get rid of the vibratioN!

Thanks all...did the rotation gig already...will continue to work the problem and take some of your suggestions (rotors, drivetrain) to the dealer and see his response.

New Owner of a silver 2006 CTS with Luxury pacakage and have the same slight wheel vibration. Of course more pronounced on different roads. Noticed so far with 325 miles that the rotors still have something on them and grooves already starting. Thought one rotor(front left) might be warped because the brake pads arent cleaning them up only spots so far. Dont want to spend my life at the dealer and I will drive up to 1000 miles before bringing to the dealer. Thanks for posting this. It would drive me crazy. I also hear these cts's go thru tires fast so maybe its an issue in design. Who knows.

Definitley abrake pad or caliper issue and is now becoming a rotor issue. Have them looked at immediatley

Anybody know if an out of balance rotor(s) can cause a vibration?:hmm:
Most definitely...I had an issue with wheels whereby I told the dealership they must use a hand torque wrench and the correct ft. lb. torque for the wheels. They dealership chose to use "torque sockets" that I loathe and bingo warped a front rotor. The vibration showed up around 60-65 mph. When I asked the dealership, the guy was honest enough to admit he used torque sockets; he used a torque socket that was 15 ft. lb. over what the torque value was that I gave him.

Here's what torque sockets are: http://www.sjdiscounttools.com/lt1593.html

Brought the car to the dealer today and he told me to put some more miles on it and if the rotors didnt clean up and the wheel vibration and brake vibration didnt go away bring it back and he will cut the rotors. The car was on the lot for 4 months. Do you guys think that would have warped the rotors?

socadillac thank you,

I guess I should put at least 500 to 1000 miles before letting them touch my brakes/rotors?
Some more info please? Is your CTS a stock luxury package with the factory wheels or aftermarket wheels? When you returned to the dealer did they actually look at your car and wheels or simply tell you that you should drive additional miles before returning?

This is what happens when you do not bed in your rotors and pads.
