Cadillac CTS Maintenance and Repair



  • ralph39ralph39 Posts: 2
    Message to #122. Why spend money when you don't know what to spend it on? Tail light can be fixed with a small socket wrench(metric #10) and a bulb. just take out the panel in the trunk, and unscrew the nuts(4). The whole assy will come out from the outside, and you change the bulb. Oil change OK, air filter change OK. Save the rest for when things fail, like brakes, exhaust, etc.

    assuming you have followed scheduled maintenance to this point...what about fluids, such as transmission, coolant, brake,..when were they replaced last?....also surpentine belt?? stated year left on the tire, I would rather see tread depth...use the penny trick...insert into the tread with lincolns head down..if you see the bottom of his head..time for tires!

    Do what the owner's manual says.

    I have a 2005 CTS Cadillac and I had an oil change about two weeks ago, but the oil change % on the monitor never went up or. IS that normal?
  • darv904darv904 Posts: 2
    my 2005 cts has been doing that for a few weeks now, when i accelerate it does that shuddering/jerking type motion, i also noticed usually when it does this the check engine light flashes? the monitor says my trans fluid is low, wonder if it could ne the problem?

    That should simply mean that the dealer, or other shop, where you had the oil changed did not go into the digital information center in the center stack of your dash and change the oil % number.

    This has to be done manually in the onboard computer (it does not happen automatically just by virtue of changing the oil in the engine). Cadillac dealer service departments are of course trained to do this.

    In your owner's manual it provided instructions on how to do this. You should be able to do it yourself with the owner's manual instructions and pushing a few buttons.

    Have you figured out how to reset the Oil Life Monitoring System? Please let me know if you have any further questions.

    Since it says that, I would definitely recommend checking and adding fluids. I would also recommend having the vehicle checked out by a dealer. Please keep me updated on your concerns.

    Obviously this is a very old post but I would like to know if you found the problem in the door. I am experiencing the same rattle when closing my driver's door.
  • gmcustsvcgmcustsvc Posts: 4,251

    Were you planning on taking the vehicle into the dealership to be fixed? Please keep me posted on any information.

    Thank you,

    The third dealership I took it to with this issue, Moore Cadillac in Chantilly, VA, diagnosed the cause which -- if I remember correctly because it's been over a year now -- was from a rain water drain piece inside the door (at least that's what I was told). They shored it all up by installing some foam rubber material to stop/absorb the rattle/vibration. It has been fine since.
  • I bought my 05 CTS exactly 4 years ago and have had numerous problems ever since. Where do I start!!!! Serious trunk water leak when it rained. Brake light continually going out. Uses a quart of oil about every 600 miles ( Dealer said this was an acceptable range with Cadillac. YOU'VE GOT TO BE KIDDING!!!!) First time I checked my oil after my initial change it had about a quart left in it. I now keep oil in my trunk and check often. Often when I turn in to a parking space moving slowly the brakes fail. The Dealership could not find the problem but said it might be a wheel sensor. I've had the EBCM replaced twice and this hasn't completely solved the problem (EXPENSIVE REPAIR). It is still doing the same thing but less often. The rear wheel bearings had to be replaced recently because the sound in the back seat was getting unbearable. Now we are having problems with the power windows not wanting to go back up after leaving them partially down in hot weather. I personally think that GM should OWN UP to these problems and work with the consumers that keeps them afloat. Just look at all the posts of people that have the same problems with these vehicles. I personally will not buy another CTS. I owned a 1991 Caddy for years and had very few problems and never used a drop of oil between oil changes. I thought when I bought this one I'd have the same results.

    Thanks for reading my gripes.

    I have had it to the repair shop 4 times, I have a whining noise, first they could not hear it, took it home still have it, Took it back then they said it was the Idaler pulley, changed that. Still whining, took it to a transmission wondereing wether to keep it or get rid of it. Not the transmission but I had a crack in my drive shaft. Replaced that. Still noise, (runs great though) Noticed a leak on garage floor, my rack and pinion need replaced, still a low whining noise, any thoughts. $2400. later!!!!!!
  • I noticed this question/problem is about a year old. I purchased a 2008 CTS rear wheel drive in August of 2011 and I have the same annoying problem. There is a thump/clunk sound at usually 2 distinct times. It's when slowing down to a stop, once at 15mph and the loudest at 5mph or less right before coming to complete stop. I've had it at the dealership twice and they have yet to fix the problem. They replaced the deferential box on the second visit, but did nothing to alleviate problem. My cts now has 32,000 miles and the warranty runs out in April. Did you ever figure out the problem and had it fixed? Thanks for your insight/help.
  • I see that you've already been in to the dealership more than once for this. Have you already worked with Customer Assistance? If we can be of service, please send us an email with more information so we can get a Service Request set up for you (include your name/Edmunds username, the last 8 of your VIN and current mileage, and the name of your dealership).

    I need to know a part number and where to purchase a manual adjustment handle for a 2007 CTS. It adjusts the passenger seat back . There is a number stamped into the plastic (88897242RH) but I'm not sure if that's the part number.
  • jpfjpf Posts: 496
    You can go to your nearest Cadillac dealer. They should be able to tell you. It's probably going to be expensive. Once you find out the part number, then try an auto recycler. They may have one from a wrecked CTS. It will probably be cheaper. Good luck.
  • Did yoi happen to find the problem? I have an 03' Cadilac it will not start only clikcs when starting and lights flicker on and off and ignition switch is off. The relay switxh for the high beams can be heard turining on and off. Not even with the battery charger will it start and atarted just after it was put in the gararge. Someone help me please. Key wont come out sometimes either....till charger is put on it..
  • I have a 2009 CTS with 52,000 miles. I'm the original owner of the car. Although there are many things I enjoy about this car, it needs too many repairs. None of the repairs are due to owner negligence. Initially, there were 3 - 4 recalls. Every few months the car is in the shop. This morning, the check engine light went on. About 6 weeks ago, the engine overheated due to failure of the water pump. There have also been failures of motors/pumps within the car, such as for the power seats. This is one car that I really wanted to hold onto for as long as possible, but I am very concerned about the life span of this car. Anyone else have constant problems with other 2009 CTSes?
  • I the author of the Nov. 4 post about too many repairs. My service rep. called this morning to say I have a leak with my "O" ring and need to have he purge valve replaced. This valve deals with emissions and pressure for the gas. Cost to take care of these items is $200. Just out of warranty, so this will be out of pocket. Cost isn't that bad, however, I got lucky this time. There are just too many repairs and they're done too often. My husband has an Infiniti G35 that has maybe 85,000 miles on it. He has never had one mechanical problem with this car. He drives about 20 - 22,000 miles a year. I drive my Caddy 15,000. I see my service rep. more than some family members. What the heck? I bought my car when GM was tying to survive. My Dad always had Caddies when I was growing up. I've always loved these cars and have been hooked ever since the re-design of the CTS. My husband is now screaming to get rid of the car. Do I just have a problem car, or, is this symptomatic of Cadillacs these days?

    I also own a 2009 CTS. I have had, maybe, two recalls. At 20,000, the ignition stuck and you could not turn the engine off. Luckily, it was a business day and I was able to take it to a dealer. As Cadillac does during warranty, they gave me a loaner Cadillac. Cadillac has been good to me during the warranty period. The car now has 35,000 miles and I am out of warranty in January. This is my second CTS. I will buy another one, but not because I am going to have great service out of this CTS.

    I had a 2005 and I had a water pump go at 48,000. I traded the car after four years. I like the way a Cadillac looks and drives. I will trade every four to five years. I am waiting until the next redesign. I would never buy a Cadillac, if I wanted a car that I would drive well in excess of 50,000 miles. I do not consider them to be that reliable. On the 2005, I sold the car to friends. The engine started knocking at 67,000 and they got rid of it. With the warranty out in January, I will be wondering what I will wind up repairing at my own expense. I do have the engine, drive-line through five years.

    If you have already had that many repairs, I would move on to something else. Cadillac is not your answer to a long-term automobile. I am sure I will hear, via this forum, from people who disagree and vow how great their cadillac has been.

    Hey I have a crazy problem. I have a 2003 CTS that is acting like a spaz. A few days ago the seat started warming itself but there isnt even a button to turn it off and on. It looks like there shouldn't even be a seat warmer in this model. But the seat is getting pretty damn hot. Any help would be greatly appreciated.
  • I owned a new 2008 CTS DI and only had a power window go out and a plug coil fail in 36,000 miles.
    I have read this forum since I got my '08 and to go by the posts you would wonder why anybody would buy the CTS. I traded my '08 for a new 2012 CTSV Coupe and am still very happy.
  • gmcustsvcgmcustsvc Posts: 4,251
    We're glad to hear that you're very happy with your CTSV Coupe, miko99! Many more happy miles in the new year!
