2001 Cadillac Seville SLS from North America - Comments

Vibration at 47 MPH and 65-67 MPH.

This is a GREAT car. Goes like stink and goes where you point it. The interior is very spacious and the seats are the best. I love it runs on Regular at todays gas prices. I am still working with the dealer to correct the vibration. He has changed tires, Road Force Balance, bushings. In fairness he is really trying. I know we'll get it fixed.

Good luck.

I had the same vibration problem with my 2001 sls, until I switched tires to michelin symmetry, as a result my problem was solved, hope this helps A.F.

Shopping for a save car for my 16 year old daughter to start driving with I ended up buying a low mileage 2001 SLS.

It also had the vibration problem. The used car dealer did everything they new how to correct the problem on this car that they had bought at the car auction. When they were unsuccessful they payed for the SLS to be checked over by a local Good Year Dealer. They took the serial number and called their Cadillac contact who referred them to the "Mitchell Repair Information Company" service bulletin.

Yes our Seville was in the "Breakpoint" VIN # of 3U247643.

This is what the service bulletin said to:

"Replace both lower control arms on vehicle built prior to the breakpoint number - a newly developed hydro bushing lower control arm with improved damping characteristics has been released." This was covered under G.M.'s service information bulletin # Seville 539332. Lower control arm right is part # 25746325 and the left is #25746324.

Haldimand Motors ordered the parts and installed them - problem solved!! However the rims must be kept clean of any mud or debris as any amount seems to cause an imbalance and vibrations will reappear.

So stop wasting money on tires and get those new lower control arms installed. Good Luck!

This man speaks the truth. I too had the vibration problem on my 2001 SLS. Started with Michelin's, no change, found this comment, gave it a shot, problem solved. Thank you.
