Cadillac CTS/CTS-V



  • arby1arby1 Posts: 83
    If have the same problem with my 2005 CTS with the CDs moving when I start the car and my trip odometer going to zero.Let me know if they do anything for you .When I brought in my car to the dealer for a recall, I mentioned that problem and they said "could not duplicate." My engine idles fine and has no vibration.Consider a different dealership.I changed dealerships in NY and am now being treated much better than with my previous dealership.

    No it also happens at stop signs, that is when I first noticed it. When was your car made? See at left front door side when you open it.

    Just try a test with the water bottle and put your hands on the cowling over the engine.

    Yes you are right it is a intermittent stumble that brought this to my attention, then with further testing I decided that also built in vibrations were taking place.

    Looks like a poor design of the engine. Now I wish I would have bought a new Bonnevile, they NEVER shake.

    My dealer has been very good at looking into this, they have put it on the big machines and can not find a miss. But they seem to ignore the shaking but did mention that it was a cam problem that causes the vibration.

    This a list of some of my recent problems, that I emailed to the Cadillac dealer. They have identified that the radio or CD has a problem. I also get that description, "can not duplicate it"

    PS The dealer is really trying to get these resolved!


    1. ECM Problem

    2. On 3-24-05 turned key on and did not start, backed key off and on again and was OK.

    3. Car SHAKES at a stop sign off and on and sometimes at idol.
    You had this in recently and did not correct it! I need the guy who will fix this to drive it for 10 minutes. It bother me!!!!!!! You need to sit in the seat with your foot on the brake at a stop sign and may be wait for several minutes.

    4. When I open the door or put key in, the 6 CD's circulate for 1-2 minutes, THEN the following are set to zero.
    Trip A
    Trip B
    Gallons of fuel used.

    This has happened on 5-19-04, 6-13-04, 2-1-05, 3-30-05

    Also in early 04 took it to Allen and they did not fix it.

    5. Four buttons on steering wheel change to OTHER things, like changing Temp or changing radio, from what they were set too. OK now but this has happened twice recently . When I restart the car it is OK.

    Since obviously items 4 and 5 are software problems, call GM and see if they have a fix. I believe it also happens to others.

    I agree you have some kind of electrical problem.

    But, where the rough idle is concerned, I think you are worrying too much about nothing. The 3.6 employs a VVT system that changes the cam lobes position based on engine speed, accelerator position, and so on. At idle it is sitting on the largest end of the cam lobe which tends to induce a rougher idle, just like a car with an oversize cam for racing has a stumble to it's idle along with significant vibration.

    If you think the Acura TL doesn't experience this same sysmptom with it's VVT system, head on over to the Acura TL Owners:Problems and Solutions forum and do a search there for "rough". In truth I think you are nitpicking. Also, engine roughness at a stop sign infers you are idling. :P

    Took the CTS to the dealer today and got the CD changed and the air bag recall, only took an hour.

    Then the service mgr and advisor showed me a car with 10000 miles and it shutters and shakes just like mine at idol. They say that is what you get with the V6, as it was modified from a North Star engine.

    They say Cadillac is NOT trying to fix it, BUT they will call me if they hear anything! They also say the 2003 model has had complaints and the 2.8 ver is even worse. BUT I am the first one to complain at the dealer.

    I am an Engineer and very familiar with vibrations and have worked on engines from my Model T in 1944, when I was 14, to recently on my 1972 Comero and 1963 Cutlass. Guess I am too fussy, as you suggested.

    It is a cam problem at idol combined, in my opinion, and a fuel/air mixture problem.

    They ALSO claim no changes to the engine have taken place.

    I am now going to rename my car CTSssv.


    What I am bothered about it as it took a year to develop. I drove a 2005 CTS loaner with 2000 miles and it DID not ssv.

    I believe every body should complain about this problem, when they take the car in.

    The 3.6 liter V6 is not a modified northstar V8. It is a 60 degree V6 design that was designed as a V6. The northstar is a 90 degree V8. The shortstar V6, available in Oldsmobiles only, was a "modified" northstar V6 engine. The shortstar was a 90 degree V6 design based on the northstar V8.

    The 2003 CTS came with an Opel V6 of 3.2 liters that was a 54 degree design if I remember right. The 2004 CTS's with the manual transmissions had this engine yet. The current 2.8 liter V6 is based on the 3.6 design, but has a shorter stroke and smaller bore.
  • richerryricherry Posts: 19
    Thanks for the V6 description. The dealer was also a Oldsmobile dealer so guess they were mixed up.

    Seems like you should know if the CTS 3.6 has been modified from 2004 to 2005 and 2006. I believe some changes could have taken place. Cadillac will have to fix this problem.

    Great to know that GM's dealer base takes the time to fully learn about their products and conveys accurate information to their customer base..... :(

    Actually, most dealers are terrible at the product knowledge side of the equation, not just GM dealers.
  • sls002sls002 Posts: 2,788
    GM's web site shows that they made some changes to make it quiter. One change is the chain that drives the cams. Most of the car magazines that have tested a vehicle with this engine have thought highly of it. I will say that my Seville's northstar is not as smooth when first started up cold, as it is fully warmed up.

    Has anyone purchased the Navigation system with traffic? What has been your general experience?
  • raleighraleigh Posts: 98
    Am in the market for one of these great Caddys and would appreciate any thoughts or opinions. Is the V worth 10 Grand more than the "regular" CTS? What kind of gas mileage are you getting with each? Many thanks.
  • skuuterskuuter Posts: 144
    Only you can answer that question. Take both for at least a 30 minue test drive, preferably hiway and twisty backroads, then make up your own mind. Othewise, you're asking for other people's subjective and biased opinons, which may not match yours.
  • temj12temj12 Posts: 450
    There are several downsides to the V. First, you have to pay a 1300 gas guzzling fee listed on the window sticker. Then you have feed it with gas that is $2 a gallon. If you have plenty of money, that may not make a difference to you but it does to me. Drive the 6; it has a lot of pep. I was amazed at how fast it was when I test drove it. Also, I think you will take a bite when you go to resale or trade the V. With gas prices, I don't think it will be an easy sale. We have an 05 CTS purchased in December. We love the car. It is fast and handles great on the road.

    I too am pondering this question. I've owned the 6cy VVT for a year and a half. Since I live and work in the DC area, the traffic calls for the automatic transmission. The pep and handling in the 6cy is great. It's the best in a mid-size sports sedan I've driven. Two minor recall issues is about the extent of the repairs. I've experienced the unusual tire wear and the cd player will need to be fixed soon like you could read about from many CTS forum members. Overall though, I love this car. Looks good and feels good. The seats are under-rated. Very comfortable and no problems with 3+ hour long drives.

    Then I drove the V series once. 400HP is 400HP. Looks good, sounds good, feels good, it's all there, wrapped in a sweat $50k package. My buddy has one. He loves it but doesn't drive nearly as much as I do. He averaged 16mpg on a recent trip to Ocean City, MD. Cool thing here is, you can still put two car seats in the rear for the kids and blow the doors off the lexus, acura, infiniti, mustang tool boys whenever you want.

    So you have to ask yourself, can you work the cell phone head set and gears in traffic? Can you afford the ~15% more in gas? Can you control your self in speed zones? Oh yeah, can your wife drive a stick? Mine can't so I think I'll be getting the V ;)

    All of this, then I read about the 06 models will have a new sports package with 18" sneakers and the sport tuned suspension. Add custom exhaust, air intake and perhaps a chip and now your over 300HP, looking and sounding good. Call it a "V-lite."

    So it's a classic battle of mature husband/father versus 35 year old kid out of Manassas, VA that has some money now. I'm making a move out of my 04 later this summer, into one or the other.

    with post 6167. Got mine in Feb.Cannot imagine wanting or having more power than CTS delivers [255 ft lbs really steps out].
  • raleighraleigh Posts: 98
    Thanks for the comments, twest88. Where did you read about what the '06 models will have? Will the "new" sports package be any different from the '05s (other than 18" wheels)? Of course, I seriously doubt that we will be able to get an '06 at employee discount prices. That makes for a very attractive deal, right now, all things considered.
  • sls002sls002 Posts: 2,788
    I don't think that information on the 2006 CTS has been officially released yet. But there is an online order website intended for use by GM dealers that does show some information on some 2006 models, including the CTS. There is an 18 inch wheel sports package with its own suspension tuning shown. It will have 225/50 tires and a tire pressure monitor.

    The present discount prices may be too good to pass up. However, even at the discounted price, a CTS_V is probably going to cost about as much as a 2006 CTS without discounts.
  • raleighraleigh Posts: 98
    Does anyone happen to know where I might find the gear ratios for the 2005 CTS 6-speed?

    Many thanks if you do.
  • sls002sls002 Posts: 2,788
    first thru sixth: 4.15, 2.33, 1.53, 1.15, 1.00, 0.79; reverse 3.67; axle ratio 3.42 Note: the CTS_V uses a different transmission
  • raleighraleigh Posts: 98
    Many thanks sis002. So, it is a really a 5-speed with overdrive. Nice. :D
