    OK help me out. Will be buying a car in 1 month. I really like the CTS. Test drove a 06 3.6. My one concern is that the car seems to have a basic flaw...the rear end setup with the differential made by getrag(?). Several owners on a different forum indicate that they have had to replace whatever is causing the problems several times. Also that the problem has, apparently, still not been fixed on the 06 models (is this true?). Talked to a salesman about the problem...he said it doesnt exists, that the differential is the !best! Now, I know cars will have problems, but something as major as this that is known and has not been corrected will probably make me not buy the CTS. Did you guys know of this problem when you bought your CTS? And if you did would you still have bought it?

    As far as I am concerned it is no big deal. I have an '03' Lux Sport built for me in May of '02. The rear end was replaced about a year later when I casually metioned to my dealer that my wife said she heard a hum. I still dont know what tune it is humming although I do occasionally hear the hum. The car now has approximately 38K miles and is running fine.

    whine happens.

    It's a matter of what you're planning on:

    Happiness = reality - expectations.

    Given that we're dealing with Cadillac -- the expectations are high (as they should be). That said, the car will probably continue to run just fine, in spite of the noise.

    When I drove my new 240-Z off the showroom floor in '73, I had traded in a '65 MGB with no rear-end whine.

    In the first few months with the 240 (I was in sales and burned through the warranty 4 months after I bought the car -- back then, we were dealing with 12 mo/12K miles), I started hearing a whine from the differential. I decided to wait until it got enough louder to matter and/or to stop the car.

    When my beloved 240 met its end with a Suburban (9 years later), the rear end hadn't been addressed. The car had 223K miles on it.

    WMMV.

    I don't know if diff whine is common on the CTS. I do know that the CTS-V's (the 400 hp model with the LS6 engine) have a tendency to blow their diffs if launched hard repeatedly, and this supposedly hadn't been addressed - don't know if '06 still has the LS6 or has moved to the LS2, and if the diff changed...
  • bingomanbingoman Posts: 373
    I've heard a number of people talk about rear end whine and replacement, but I've not heard of anyone having a blown rear end.

    How hard and how often do you have to launch the CTS-V in order to 'blow' the rear end? How many cars do you personally know of with 'blown' rear ends?

    I have 'heard' of a number of people who put misleading information on these forums to discourage people regarding brands that they have a grudge against. I would verify any information I obtained through the internet before I based any action on that information.
  • hammen2hammen2 Posts: 1,313
    I do not personally know any CTS-V owners, except a couple who post on other car-specific bulletin boards I frequent (and can't post the links to due to Edmunds policy).

    I am not making this up, and am not here to bash the CTS-V, just posting what is fairly apparent. Google "cts-v second blown rear differential" and see what you get.

    Supposedly GM High Tech Performance magazine blew the diff on their CTS-V with extreme wheel hop on hard acceleration - reported in the May 2005 issue.

    (Lurkers note we're only talking about the V here, not the regular CTS).

  • I am curious about this issue as well. I've had my cts since July '05 and love the car except for that whine. My hubby says it is no big deal, but the other day I was driving through town where the speed limit is 25 (and the whine occurs at that speed) and the car did a strange jerk, like it was trying to pull me back- accompanied by a small pop noise. Then it went away and drove fine. Called the dealer, they said bring it in, which is next week and we will see.
    Anyone have this before?
  • bunoybunoy Posts: 7
    Zelda25, would you please post what happens next week at the dealers?

    bingoman, cdnpinhead, so the whine is not a big deal? I could live with a little noise, but not outright howling or breakdown. If the CTS ends up like your 240, I would not complain. The 223k miles, not the meeting with the Suburban!

    Also on another board, someone posted that they were getting a 06 diff put in their 05 CTS-V and were hoping that this would be the cure. Does this mean the 06 have no diff problems?

    Thanks for all the responses. BTW, my other choices are the 06 325 and C280. So any comments positive or negative would be most welcomed.

    In 1995 I traded my 1989 Acura Legend Coupe (which was a dream car)in on a 95 Jeep Grand Cherokee Limited. After three years of major and minor trouble I traded for a 99 Lexus RX 300. I swore at that time that I would never buy another American car based on past experiences with Oldsmobile and Jeep. My resolve has been weakening somewhat as I saw more and more CTS's driving around town. I love the styling of the CTS but am concerned about the 07 styling changes (see my other posts in this forum). Now, we're hearing about rearend differential problems, excessive tire wear and minor fit and finish problems. Maybe I should stick to my original vow and stay with Toyota or Honda as my choices.
  • Bunoy and others interested in rear diff. issues,

    I went to the dealer this morning and after doing a test drive they found gearing problems between 20-30 in the transmission. I'm supposed to bring it in and they have to keep it for a day to fix this. I could only leave it an hour, as I had a school function to attend, so this is what they found at the time. I really did not get a good reading if this is related to the rear howling/whining as opposed to the jerking back and pop sound I heard. The rear will be checked, along with the fluids during this time, so I can report back and tell what that brings.
    I just like my cts so much that I hope this can be easily fixed and I can get on enjoying the car!

    Is there an aux jack for an iPod?

    also, how is the real world MPG?

    I have an 05 CTS which I purchased in December of last year. It is my wife's car. I seldom drive it but I drove it the other night. I could not believe the noise coming from the tires. They sounded as if they had 50,000 miles. I called the dealer and he told me this is normal for the CTS. I have 14,000 miles on mine and he said that a man had brought his in this morning with 19,000 miles. He said the man was debating whether to buy a new set of tires or not. He asked me about rotating. I told him that I usually rotated every 15,000 with a rear wheel drive car. I know that exceeds the recommendation. He said that the way the CTS suspension is built that it is important to rotate every 5,000 and have an alignment at 15,000. I asked him if the body was out of alignment and he said no. My niece just traded a 350z. It ate up tires every 10,000 because the body was out of alignment. This is more maintenance than I want. The car sounds and drives like an older car.

    Where did you see side and rear view pictures?

    thebug...
  • thebugthebug Posts: 294
    jpenn Are you kidding? I haven't seen anything other than the front view, and although, it's only an artist rendition, I think it looks pretty sharp. Thinking back (on my part), I thought the current CTS was ugly, but the more I looked at it the better it looked.

    I already like this new style, and hope it's close to the rendition when it finally hits the bricks. If it is anything close to this, I will have to buy one. It would be nice in black on black. BTW, where can I find pics of other views?

  • jpennjpenn Posts: 68
    The Bug,

    Everyone has their own tastes, that's what makes life interesting. If it looks like the artists rendering you can have the one I was going to get in Black on Black.

    You can see the side view of the new CTS (which I like) on post # 6338 in this forum. It's actually a nice update of the present model, my problem is with the front end. With that said I read in another forum that this artists rendering is in no way the official design of the new CTS and it will not look anything like this.

    So I guess we'll just have to wait and see.
  • thebugthebug Posts: 294
    jpenn, Never a truer phrase written as "each to his own." I had not seen this rendition in post # 6338. I like the rear view, (I still have to get one) and you're right, it will be interesting to see what they finally come out with. My gut feeling is that it will be pretty nice, and will appeal to that segment who liked the 03-06 version. That's if they're wise.

    thebug...
  • jpennjpenn Posts: 68
    thebug,

    I agree with you re: the redesign, they'd be foolish to make a drastic change after getting such a huge bump in sales from the present design.

    I'm still concerned about the nagging problems they've been having with the drive train and tires.

    After reviewing the IS 350 forum I've eliminated that car from my list (too small and too much of a performance oriented car). So I'm down to the Caddy and the new TL, I've also been eyeing the CLK320 coupe but it's a little pricey. All will need AWD in order for me to consider.

  • I have a black/black 2004 CTS with luxury sport package, purchased here in Toronto in April 2004. I don't drive all that much so I only have 6,000 km (around 3500 miles), and the other day, while driving on a regular road, the car just died -- no power, steering wheel "locked", nothing, but I was luckily able to give it enough power to turn the wheel and park it on the side of the road out of harm's way. Thanks to OnStar, the police showed up and then a tow truck, and I was towed to a dealership (closed on Saturday of course). This morning they called to tell me the car needs a new fuel pump (!) and that this is a typical CTS problem. I am the unfortunate past owner of a 97 Catera, and while I realize the CTS is a far cry from that abomination, I'm already nervous that in this early stage the fuel pump needs replacing. Has anyone else had this experience? I've also brought the car in for 4 recalls, and for complete replacement of the DVD Navigation system due to inaccurate location and direction reporting (apparently also a known issue). I am about ready to dump this and go to a Honda Accord but am wondering if I should wait and see. Thanks.

    I haven't found any reports of fuel pumps being a typical CTS problem. It seems that the problem would appear on this site if fuel pumps really were a common problem.
  • have you added any fuel conditioner or fuel cleaner to the tank?...
  • I was wondering the same thing when a few days ago, I was pulling out of the parking lot in my brand new 2005 CTS when all of a sudden, the car felt as if it was about to shut off. I could not believe it. First thing I said to myself was "I know this isn,t happening and this is a brand new car". Is this a problem with CTS? I was so proud when I first bought it. I thought I was getting a good car.
  • So the fuel pump was replaced. I asked if the fuel gauge was also replaced but was told that the problem with incorrect reading was tied to a sensor in the fuel pump, so that should all be fixed now. Well, driving the car away from the dealer after everything was "fixed", I noticed the needle bouncing all over the place. I turned on the "Fuel Range" item in the DVD Nav screen, and it too jumped around the place like it was playing hoops. Called dealer when I got home to ask if they even tested this, and was told "call us after filling up the tank if it persists". Super. Researching on www.nhtsa.com just a few minutes ago and found at least 2 other reports of 2004 CTS dying because gauge reports full when in essence tank is bone dry, and that the "Fuel Range" is totally inaccurate. I am selling my CTS as a result, I'm too nervous about all this. :mad: :lemon:

    I'm almost in the market for a new car, and had pretty much excluded the CTS because of price...even though I like the look of the car very much. I saw an ad in my daily newspaper this week for a dealer about 3 hours away who is cutting some good deals on the CTS...a base 2.8l version with automatic which lists for @ $32,400 on sale for @ $24,800 (granted that's through a "SmartBuy" deal, but still seems like a bargain). This brings the car down within a range I'd consider...any known problems or concerns with the 2.8 engine to keep in mind? I don't think I'd want to spring for the larger engine at this point, so if the 2.8 should be avoided that answers my question...but if the 2.8 is a good engine, I'll give it a closer look.
  • sls002sls002 Posts: 2,788
    The 2.8 engine is very similar in design to the 3.6, but does have a shorter stroke as well as a different bore, so is not the same engine.
  • nosirrahgnosirrahg Little Rock, ARPosts: 872
    What about in terms of reliability, NVH, etc.? I guess I'm just trying to make certain there aren't any glaring reasons NOT to buy a 2.8 CTS.
  • sls002sls002 Posts: 2,788
    Since the 2.8 is very similar in design to the 3.6, the NVH should be similar, and reliability should be similar. The power output is less and there does not seem to be any increase in fuel economy. The big difference is that the 2.8 has about 23% less torque at the peak, which is at the low speed end of the torque curve, so this is significant.
  • I would sell more 2.8's, but there is NO fuel economy benefit. If it was 2 mpg we would sell many more.
  • sls002sls002 Posts: 2,788
    The difference in price is not enough to make the 2.8 worthwhile either. The 2.8 is probably a bit less expensive to build, but probably only by a few hundred dollars.
  • panzerpanzer Posts: 125
    Before I bought my 2005 CTS, a local Cadillac dealer told me to stay away from the 2.8, because of a problem with the engine seizing. The dealer said he had personally had several that had the problem, and he would not keep any 2.8's on the lot, even to offer as a price leader, and that the 3.6 was his recommendation. Last summer I looked at three dealers, probably 75-80 CTS's in all, and saw only one stripper 2.8. I did not drive it, but that dealer was dying to get rid of it. I bought the 3.6 with luxury and sport and I'm delighted with the performance, ride and comfort. Think BMW without the cost, but with much better seats. It has about all the grunt I can use without bringing a lot of unwanted attention. I don't know if there is any equipment decontent associated with getting the 2.8, but I can tell you the CTS is a heavy car and the 3.6 gets it moving very adequately. Average mileage is 19-20 mpg, not great, but better than what I would expect for the performance level. In 5500 miles, no issues, no visits to the dealer. Hell, it looks like I won't even need an oil change till 10k, even though I'll probably get one soon.
