I purchased a 2000 De ville last month and have been experiencing the same vibration as described by other owners. The vibration occurs between 63 and 73 MPH, and is most severe when applying the brakes. I assumed the rotors needed replaced, but I am glad I did not have that done, it appears it would not have solved the problem. I guess it's time to sell.

I had a 2002 STS that has the vibration problem. Dealer changed tires, cut rotors, changed control arms, tried new rims, changed tie rods, the thing still vibrated. Contacted Cadillac customer service, They had no answers. Dealer finally admitted there was nothing more they could do. Next call I made was to a lemon law attorney. Received cash settlement and dumped the car. That's the only solution to this problem. Always thought a Cadillac was something special. I guess I was wrong. Never again will I ever consider another one.

We purchased a 2002 Seville SLS new about two years ago. From the beginning, we experienced vibrations. It has been back numerous times to two dealerships. Problem still exists. Cadillac replaced the tires with the same type of Goodyear. The car has been in for service weeks at a time. No improvement. Cadillac refused to try the Michelin tires and today I had Michelin tires(hydro-edge)put on the car at my expense. To my dismay, the vibrations are still there as others of you have indicated. I wish I had looked at this website earlier. The Cadillac assistance people act as if I am the only one with the problem. The standard reply is that the technicians have done everything they can do and that the car meets Cadillac standards. This is our 5th Cadillac and the others were excellent cars and the service for them was excellent. Someone please post how to go about obtaining help in using the lemon law.

We own a 2000 Deville with the same vibration problem that EVERYONE seems to be having. It starts at 55 to 75 mph and seems to get worse steering toward the right. Has anyone had problems with their A/C controls? The drivers side air doesn't get cold,while the pass. side and rear work just fine, after its been on for 20 or so min. it starts to get cool, but not cold. Also has a funky smell when A/C is first turned on.

I am so grateful that I found this site. My 2002 Cadillac DeVille Sedan, 31,500 miles, is at the service department for the 9th time related to vibration problems. My problems started at about 18,000 miles and has continually gone down hill since. I have, at my expense, had five new tires (Michelin Symmetry) put on the car, had the rotors replaced, replaced the tie rod ends, had the tires balanced 4 times, replaced one of the rims on the car, and most of all, made to feel like I was a complete idiot about complaining over the vibration. I was told that there was not any type of report from Cadillac about such a problem and that, basically, they had done all that GM said they were required to do. This is my fourth Cadillac and am disappointed over the customer concern I have received. You have read throughout these comments the problem I am experiencing; vibration at all speeds, most severe at 60-73 mph, a wavering effect when braking, seat, floor board, and steering wheel vibration, and continuous trips to the service department. The service manager has been very nice to me, including putting a brand new set of Michelin Harmony tires on the car just yesterday. The result=the same vibration. I am asking that anyone who has success with the lemon law approach to please email me because I can't tolerate the ride I have any longer. A $50,000 car should not ride the way this car rides.

I bought a 2000 DHS with 30,000 miles on it and it developed a vibration at 60 to 70 mph. I tracked it down to be the seal on the left side drive axle. It was leaking whenever we turned the wheel and when the shaft was pulled it was found to have worn. The race was worn and the new seal was a temporary fix, the vibration disappeared.

I am now having the trans pulled because the race gets replaced from the inside. Pricey...

It's NOT the tires. Tires do not "cause" vibration due to make or construction. This is a cop out on GM's part.

Den.

Have a 2003 De ville. I have approx. 4500 miles on the car and have I believe 5 sets of tires on the car. I am now running Goodyear Regatta tires. Vibration is down, but not gone. Something of interest about this issue. Yesterday my car sat all day in my garage. We had a very cold night and this morning when I drove the car the vibration was very bad. I have a tire pressure monitor in the car. I noticed that the tire pressure on the front 2 tires was at 28. As I drove it went up to 30. There car started to smooth out as the pressure went up. I don't think the tire pressure is necessarily the reason it started to smooth out I think it has more to due with temp. I bought my car in Sept. and I think the vibration has gotten worse as the weather has gotten colder. I am starting to think it is a suspension problem more than a tire problem that GM is pushing people toward. I have talked to a person who eventually got rid of the problem. It is not every De ville that has this problem. There has to be some common thread on this problem. I have had the road force balance and started out with Michelin tires. My vibration is better than it was. It is still not good. Tires have helped mine, but I think it is another problem.

Own a 1987 Cadillac Deville. Same vibration problem everyone describes. Replaced all four tires, no joy. Still feel a harmonic vibration that resonates up from the seat through the pedals to the steering wheel then back the opposite way. Had this problem with a 1999 Nissan, and now with a brand new Mitsubishi Lancer. But I would not expect it in a Cadillac. Here is my 2 cents worth: I don't think there is any such thing as a perfectly balanced hub/wheel combination, and I don't think there is any such thing as a perfectly round tire. Either (or both) of these situations on any one wheel, and you've got vibration that is almost impossible to diagnose. You can prove this to yourself by first ensuring none of your tires have more than 1/16 inch radial or axial run-out. (just jack up the car and spin 'em) Replace any that exceed these limits. Then have your wheels balanced "on the vehicle" by a tire shop that performs this procedure. Your vibration problems will disappear, but forget about rotating your tires or changing/turning brake rotors/drums. Just a bit of info, every Dodge/Chrysler mini-van I ever drove was smooth as silk up to 100 mph.
