I am looking at a 2000 De-ville and had no idea that they had such troubles. My mother owns a 2003 that needed a new torque converter at 25000 miles, but no vibrations as of today. I guess I will look at the Toyota Camry's again. As much as I want a De-ville, I will not deal with these issues just to have one.

I have a 2000 DTS with 74K. The display says "Service Air Bag" and "Service Stability System" anyone else had this happen? LOve the car otherwise.

I have a 2000 Deville and what a piece of crap! I have gone thru 2 water pumps, 2 airflow actuators in the dash, 3 window regulators, transmission rebuild, motor mounts, main engine seal, vibration at 70mph and now I need to replace both crankshaft sensors. It only has 68,479 miles. This is my second and last Cadillac. Never again. I had a '94 before this one and I am done with them. If any of you have a Service Engine Soon light on and the code is 93, it means the Torque Converter Clutch needs replaced. The only way to do this is to remove the tranny which is expensive ($3500). I opted to have Aamco replace it (non-Cadillac Torque Converter) with a rebuild which included the electronics kit for $3600. This kit had all of the sensors and solenoids in the tranny. It (at least the tranny) has worked great since last May '06.

My advice is... DO NOT BUY this car!!! Consumer Reports was right.

I have a 2002 DTS with 85K. The display says "Service Air Bag" and "Service Stability System" The stability system has actuated on dry pavement at 30 MPH. Dealer has not been able to fix it yet. Also had the vibration problem others have described. Installed new Michelin tires. Keep tire pressure above 30 PSI. No more vibration.

Hello Fellow Cadillac Owners. I bought a used 2000 De Ville with 36,000 miles on it about a year ago and it was fine til a week ago. My windshield wipers won't turn off. They seem to be stuck in the on position with the windsheild fluid spraying every where. I've tried to change the fuse thinking that would fix it, but no luck. Has anyone else had this problem? If so please any help would be grateful!! Thanks, Joseph.

2000 Cadillac Deville not DTS or DHS. second owner. Bought it with 58,000 miles now at 84,455 has been great, but my ignition coil assembly went bad along with my water pump. It also vibrates. Since about 60,000 the service engine soon light goes on and apparently the (AIR) Air injection system has a faulty sensor. Im kind of jittery about the transmission. Anyone got an idea when it gives out so I can be prepared for the cost?

I love this forum because it is very informative. I recently bought a used sls with 60,000 miles on it and 4000 thousands miles later I have to get two crankshaft sensors at a cost of 500 bucks for the total cost which isn't that bad. I have not had those vibrations problems which makes me kind of glad to pay for the sensors. I have cooper touring sle tires on my joint and they work fine. Duralast sucks.

1999 Seville and same issue on vibrations. Replaced tires 4 times and finally ended up going back with the Symetry tire from Michelin. No luck. Still issues at 65+ and it's driving me nuts. Here is what I have done with no success. Replace both front CV axles by recommendation of a Cadillac buddy of mine. Replaced the rims with new factory rims, but a different style and replaced rotors so many times I can do it in my sleep. I did watch the new tires on the balance machine and did see some side to side tread movement on the Michelins. I was also told the torque converter was probably the issue, but when you put the car in neutral at high speeds my mechanic buddy told me if it were a torque converter the vibration would stop. It didn't so I doubt that will correct the issue. I do notice that the vibrations seems to be worse when you accelerate going 65+ miles or faster. Anyway, will try the Goodyears as a last resort. If that doesn't fix the problem then I'm selling the car.

I recently purchased a 2000 DHS Cadillac with 38,000 miles and now at 40,000 miles, it shuts off while driving, usually at stop lights or at slow speeds while turning into a parking lot, Thank God! Has anyone experienced this problem as well, Please let me know for I can prepare myself for costs!

I had the same problem our 2000 DHS Deville would stall out at stop lights or when making turns into garage or parking. Both time’s it was the fuel sensor that needed to be replaced. First time under warranty second time cost us

$500.00. Good Luck.

I bought my 2002 Seville SLS back in November of 2004 with 50,040 miles on the clock. The tires needed replacing as they were the originals. I noticed the vibration and figured new tires would correct the problem. How wrong I was.

Before I get into what has been done, let me first state, that I love this car and will not be getting rid of it. Okay here goes. I made it my mission to diagnose this issue. I have read everything that I could, and have gained a lot of knowledge. I do all of my own repairs, so that keeps costs way down. Since I bought the car, I have had 5 sets of tires (all new except the originals) and four sets of wheels on the car. None of them cured the 60-75 mph vibration/shimmy. I have changed the two front struts with new Delco units, as well as the rear shocks. I have changed all four wheel bearings. Also changed the outer tie rod ends. I have changed rotors twice as well as the pads. I installed a new front engine mount (supposedly a weak mount that often fails). I tightened up on the engine cradle. And the car still shimmies. But I still love it and will continue to drive it.

Now for the necessary repairs that needed to be done. Trunk was leaking water. I replaced the trunk seal as well as using weatherstrip sealer around the entire perimeter (about $55.00). Trunk no longer leaks. I had an acceleration issue where the engine would bog down badly. Changed the MAP sensor and it runs great (about $45.00). I had to change the water pump cover gasket as it was leaking when I bought the car. Since I was changing the gasket, I figured I would replace the cover, thermostat and gasket, install the coolant supplement, and add fresh coolant (about $85.00 total). Coolant hasn't leaked a drop in two plus years. Crankshaft position sensors needed replacing due to sudden engine stalling (about $80.00). Most of my parts were gotten from www.gmpartsdirect.com.

Existing issues. I have a transmission problem. It is throwing code P0741, which is the torque converter clutch stuck off. Basically the torque converter doesn't come to complete lock up, resulting in slightly lower fuel mileage. Cost to repair is well over $2,000, so I will live with the code.

For all owners of 1998-2004 Seville's, and 2000-2005 Deville's: did you know that you can run diagnostic codes directly from your dashboard? No need to go to the dealer. Here is how it is done. To the right of the steering wheel is three buttons on the dash. Simultaneously hold in the on/off button and the ^ button. After a few seconds the dash will weird out, go blank, and then ask if you want to run codes. Press the on/off button two times. The car will now run through the codes. It will also tell you if the code is current, or history. After retrieving the codes, it will ask you if you want to delete the codes. If you do, hold in the on/off button until the codes clear. If you do not, just press any of the buttons on the left side of the dash. You can run the codes while the car is being driven, or at a standstill. A very nice feature to have in a car.
