    My 2003 Deville (Base model) (44,000 miles) makes a creaking noise when pulling ahead from a stop at normal speed. This has been diagnosed as a worn strut bushing and is covered under warranty. The car is in the shop for repair. This is for the information of those who may have the same problem. By the way, my 2000 LeSabre had the same problem at 12,000 miles and Buick refused to fix it. I soon sold the Buick (should have invoked the Lemon Law) and have switched to Cadillac for good. Warranty support for Cadillacs at least at my Cadillac/Chevrolet dealership has been great - far better than for any other GM car I've owned.
  • The reception on my XM Factory installed radio on my CTS is less than satisfactory. While on a recent vacation I rented a Buick LaCrosse I received XM reception while even in a parking garage! With my new CTS the reception cuts out numerous times and makes the Buick look like the luxury car. Anyone have any suggestions?
  • hi there
    I just had major problems with my 1991 DeVille. Had to replace the evaporator and the engine control module/computer. spent a lot of money and now they tell me that probably the body control modul is also not working properly. same with the control modul for the climatic, now that I have cold air it's only blowing out to the windshield, the other fans do not work.
    do you think that the different modules/parts are identical with your car?

    How can I disable or bypass the Drive control alarm message on my 96 Cadillac Deville?
  • blkhemiblkhemi Posts: 1,717
    What do you mean by drive control alarm message. If it is up on your DIC, then you must get it checked out.

  • i own a 2003 cadillac cts, since some time ago, the information center suddenly turns off, and restarts a few seconds later.

  • (cross posted in Cadillac CTS forum)

    OK, need your help on this one:

    2003 CTS, 3.2L, 5spd automatic, 57,000 miles, build date March 2002.

    Owned since new, all service per schedule, Mobil 1 since 10k.

    Check Coolant Level warning light came on a while back. Level was down about 1/2" below "Full When Cold" line, so I topped up with 50/50 Dexcool/H2O mixture. Figured that after 3.5 years and 55k+ miles it was normal. Took about 1.5 quarts of coolant mixture to top off.

    Week later, noticed a small (3") stain/puddle of coolant on the driveway after being parked for a few days. Fluid level still OK. Another week or so of regular driving, level down again, another small puddle.

    Dealer service put in the tracer dye, and tell me the leak is from the rubber seals on the engine oil cooler that is (inexplicably) placed under the intake manifold. Its purpose is to regulate engine oil temperature, and it is apparently a similar design as the Opel engineered 3.0L Catera DOHC engine on which the 3.2L is based. Dealer is aware of similar leaks in the Catera. :lemon:

    Here's the problem:

    The thing is so inaccessible that it's 6 shop hours to R&R, and when they get in there, it could require replacing the cooler itself ($250), all of the lines, etc. Since the seals are rubber (O-ring?) type, and not regular gasket material, dealer says adding leak-stop tabs won't work. :cry:

    So far, no coolant in engine oil, no catastrophic leaks. Does anyone have an opinion/recommendation on what to do here? I'd prefer not to shell out upwards of $700 to fix what is currently a "nuisance" leak, but don't want to risk major engine damage, either :confuse:

    i recently had a message come up on my message center that read speed has been reduced to 90mph. Anyone have a clue as to what this may mean?

    THEY KNOW THEY HAVE A PROBLEM !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
  • blkhemiblkhemi Posts: 1,717
    Did you also get a message that said " TOP SPEED REACHED- REDUCING SPEED"? If so, then you must've been going mighty fast.
  • blkhemiblkhemi Posts: 1,717
    7-quarts in 3000 miles. That's almost the whole oil pan's worth of oil. Oh, GM definetely would've been buying that car back.
  • mikkismikkis Posts: 2
    no just message stating speed reduced
  • blkhemiblkhemi Posts: 1,717
    If the message comes on as soon as the car is started or when the vehicle gets upto about 35 miles an hour, then you should get the VEHICLE SPEED SENSOR checked. Sometimes the sensor can throw out intermentent codes to the computer and it will in turn flash it on your DIC. If the car drives normal, then this may be it.

    But come on Swede, 7 quarts in 3,000 miles. Way excessive, wouldn't you say? I have both my '03 DTS and my '05 STS V8 AWD and neither has never burned that much oil. The most that my '03 burned was a 1/4 of a quart because I was too lazy to change the oil at 3,000 miles. I know the Northstar burns oil, but this absolutely insane.
  • I have a 1993 Cadillac that needs to be smog checked for California registration. The "Service Engine" light has come on so no one will check for smog status. Everything I can find indicates that I may be able to remedy the problem by replacing the ECM. I have a new ECM, problem is I am unable to find the location of the old one. I have read it is behind the glovebox, no! I have read it is in the airbox, no! Does anyone have any idea where I can find the ECM on my '93 Seville?
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 64,490
    Hasn't anyone pulled codes to find out why the engine light is on? Replacing the ECM without reading codes sounds like a bad idea.

    I purchased a 2002 Escalade Certified Used Car from a local dealer. The car had 39,000 miles on it. I have owned it for 2 years, we use it very little around town etc., however we will be driving to Florida in a few weeks. My concern is that at 44,000 miles when we had the vehicle serviced the front end was severely out of alignment. The dealer said that the rear left tire belt had failed and that we must of hit something. Reluctantly we paid for a new tire and alignment, but explained to the dealer that neither of us remember hitting anything, especially hard enough to ruin a rear tire. Now at just 49,000 miles the car is doing the same thing. We are scheduled for service this week. Are we to expect the same story? We know we did not hit anything. Should we take it to an independent mechanic rather than the Cadillac dealer?
  • blkhemiblkhemi Posts: 1,717
    Always,Always,Always get a second opinion.What you are in need of is a 4-wheel alignment, not just the front. It is in my opinion that the Caddy dealer is messing around. A vehicle that is rarely driven shouldn't have this problem, especially since no one remembers hitting or running over anything. I'd take it to an independent shop like a Goodyear but certainly not Firestone, and let them look at it, I've had my DeVille there on occassion and they fixed things the dealer said they couldn't fix.
  • i own a 2003 cts, suddenly when driving, the center information display and the sound systems turns off, and on and off and on again,,, it could be some 2 to 10 times continously, till it turns on again and stays that way.

    Could any body help me ?

    Another problem,,, the front lights, the right one seems to point in a different direction than the other one, it seems to be not alligned ... how could i allign this xenon lamp???
  • I recently bought a 94 STS and the ac dont work....we took it back to the place we bought it and when they attempted to put freon in as soon as the seal was broke on the freon can the car instantly just shut this a safety measure or is there something drastically wrong??? anyone know about this????? also what is the normal coolant temp for a northstar v8 (I believe 4.2?) it seems to be running about 210-225 is that normal....we didnt get a owners manual (Im still working on that!)
  • blkhemiblkhemi Posts: 1,717
    The car shouldn't be running if there is freon being installed into the compressor. This can be very damaging. The car does indeed have built in sensors to detect when something like this is going on. Your engine size is 4.6L and the operating temp is within normal range.
  • My wife had a similar problem with her 1993 Fleetwood although in her case it was not intermittent. She was preparing to leave on vacation and the trunk lid pull-down failed. I saw no obvious mechanical or electrical faults. I purchased a replacement mechanism from the dealer ($93.00) and installed it myself. The trunk pull-down then operated flawlessly until we later purchased out 1998 Seville STS.

    The installation required removing the trunk lining and removing the inoperative unit. I had to disassemble the pull-down mechanism housing and install the new part. Elapsed time was about 20 minutes start to finish. You should be sure that the mechanism is lubricated properly with white lithium grease.
  • '96 Cadi STS had a significant fluid leak only noticable right underneath transmission on garage floor (puddle). It was viscous and orange-red. My first thought was my transmission pan is loose and leaking transmission fluid. I was told by the garage repair shop I was wrong. They said it was radiator fluid. They want to charge me $280 to repair the "radiator" leak.

    Two things:

    1. There is not, and hasn't been, any evidence from fluid leaking around my radiator (not obvious), and there was no 'snail' type of trail from beneath the radiator; so I don't know why it puddled up below the tranny. How can tranny fluid be of an oil consistency and at the same time orange-red?

    2. The repiar shop wants $280, but in a couple of weeks, I want to trade it in on a new Cadillac DeVille. Am I going to see any residual benefit from repairing this before I trade it in?
  • Antifreeze is usually green or yellow. Tranny fluid is red. However the tranny fluid is cooled via the bottom of the radiator. I'd get a second opinion.
  • I inherited this junk in the 90's and I am determined to make it to 200K with the second engine. However when I replaced the engine and then went through emission testing (which is a total joke) the test for the third gas Nitrous oxide (NO) failed by just a hair. Now this car had been tested before for the two gases HC and CO and passed. Lately it has failed NO limits worse than the first time! What gives emission testing the right to test for NO when the car was not tested for it from the beginning!? Were 1985 cars built to meet NO limits in NON California states? Does anyone know how I can get the specs from a 1985 window sticker that should state the compliance? I don't think this car was meant to meet NO limits.
  • blkhemiblkhemi Posts: 1,717
    Your garage shop was indeed correct. The Northstar engine that is in your STS has a coolant formula called DEX-COOL. It has a orange-reddish color to it, unlike the green associated with regular coolant.
