We have a 2000 Cadillac deville with 120000 miles. It races in idle and shifts real jerky. When you are driving it, you can feel it shifting. We have replaced the map sensor and are being told now it is the throttle sensor. The service engine light comes on and after a while goes out. The codes have been read. Sometimes it feels like the whole bottom is going to fall off. Has anyone had this problem?

Look out for that P0741 Torque Converter code. A lot of you said you were going to ignore it because of the cost to repair. Bad idea. The transaxle will overheat significantly at speeds over 45 MPH and especially at highway speeds; anytime the converter would be commanded by the PCM to lock up. This is caused by the increased speeds the internal components will be spinning at with no lock up. Instead of just the converter, you'll be replacing or rebuilding the transaxle, too. It will evetually become so damaged that the car is not drivable. $3800 to rebuild my transaxle and install a rebuilt converter. I've owned three Northstar Sevilles and a 2002 DTS. The DTS needed $15,000 worth of mechanical and electrical repairs the first three months I had it. Friends don't let friends buy 2000-2005 Devilles. Save a life and a bank account at the same time. Stay away from Eldorados, too. They'll really make you pull your hair out. Peace.

Cadillac vibration.

Check this site - we can complain and even see class action suits.


Also someone raised the same problem with Cadillac vibration.

In July of 2000 I bought a 20000-Cadillac De Ville with "all" of the bells and whistles. Had a fabric top put on in the same cashmere color. Paid about $45,000. My 3rd Cadillac. Have had "3" window electric function parts break and the window just completely falls down in the door. So, it has to be repaired! Cost: front--$385.00 back--$509.00! Never, ever used the front passenger or back seat windows! Window part is 'plastic'. Only have 77,000-miles and keep it in the garage. Live in Waco, Texas and there is one glass business who just does these windows because they break sooooooo often! This is ridiculous! "Cadillac" name is seriously hurt because of it. But, do they care??? Very disappointed!!!

This plastic window part seems to affect many of GM models around 2000. Look at many of the Buick and Pontiac reviews from that time.

Please help. I have a 2000 DHS.. I had the service stability system come on, on the computer, and have this annoying humming noise while driving, that gets louder the more speed the car is going? Can someone tell me if they know what's going on, and how much it will cost?

Thanks for all of the input to date. I have the vibration/shimmy and have started to do checks on the various parts listed as the possible culprit. The window regulators were a real let down with my 2000 DTS... three of the four failed in less than a year. Thank goodness for Ebay... Cadillac wants $560 a piece, Ebay has the regulator (use the existing motor... because it normally does not fail) and it is about $100 per window. The "Check Coolant" light comes on due to a frayed sensor. I found that you can't replace the sensor (even though it can be removed)...will have to absorb the $70-100 for a new surge tank.

New issue that didn't previous see listed... clogged evaporator drain hose. Go under the car, passenger side at the firewall, near the cat converter, find the drain hose. Stick your finger in there and let the crud pour out...nasty. The symptoms for this problem were water on the passenger side floor and condensation under the dash. Smell the water, if its coolant... you have a whole other issue.

I have a 2000 Cadillac De-ville DTS. The Service Engine Soon light just came on; code reading torque converter stuck off. Does anyone know the cost to replace one of these things. I have priced it at $177, but how much will labor be?

I have a 2003 Oldsmobile Aurora that I have entered in the Oldsmobile section of this website. The suspension and chassis must be identical to the Cadillac since I have the identical problems with my Aurora that Cadillac owners are experiencing. I am skeptical about purchasing these new control arms that are listed in the technical service bulletin that are suppose to solve the problem. It seems to me that nothing solves the problem. Some part must have worn out, it wasn't like this when I bought the car. I can't honestly even sell this vehicle on the open market without warning the potential buyer of this problem. I drive from Detroit area to Ft. Myers Fl. with this vibration for 1350 miles. I have a lot of time and money in this problem.

The Aurora did not share the chassis with the DeVille. The 95-99 body style shred it's chassis with the Seville, Riviera and Park Avenue. When the Aurora was re-designed in 2000 I am not sure it kept the same chassis as it was downsized somewhat. None the less, it never shared it's chassis with the DeVille. I drive a Park Avenue, and I really don't have much noticeable vibration at highway speeds.

I bought a 2001 DHS with 48,000 miles in August, 2007. Beautiful car but problems. Today replaced valve body because 2nd gear didn't work. At the same time replaced front motor mount. Replaced spacer plate gasket and pressure switch for a total amount of 1,500. But wait there is more. Three weeks ago replaced crossover gasket and intake valves for about 900. One month after I purchased the DHS, I had to have fuel filter replaced and injectors flushed. I am about 3000 in the hole with repairs and maintenance. Love the car but don't know when its going to end. Oh yeah it also vibrates some around 70 mph and the plastic frame around the passenger rear window is separating from the door.

I have a 2001 DeVille with 111000 miles. The driver side A/C blows warmer air than the passenger side or rear zone which is cold. I am told a "hose" has a leak in it. Anyone know what hose they are talking about.

So I sold my 2002 Accord and purchased a 2000 Cadillac DTS with the funds. Biggest mistake of my life.

I got the DTS with 83,000 miles, and I have had nothing but problems. I replaced a coil box that hit me for 800. Then I changed the rack and pinion, outer tie rods, the front engine mount, another 1000 in parts alone, I had my friend install the part for free.

Three months later the tranny goes out, 3000 dollars more. After the tranny got replaced, the mechanic left a coolant leak, which led to my alternator going out, another 550, just for the part.

This car has turned into a nightmare, and I've only owned it for a year and three months.

I have a 2004 Cadillac Deville which I bought three years ago and it now has 75,000 miles on it. I just recently noticed front end vibration at about 65 MPH. I had the car checked at my local brake repair facility and they could fine nothing wrong. They replaced the front driver's side wheel assembly twice prior to this visit. They said I could stand some new tires on the front, so I replaced them but still have the vibration. I went to another repair facility and they told me it had to be the new tires so I paid to have them balanced again and the vibration was lessened, but it is still there.
