#9 of 27 Bumpy Ride? by apatt Dec 03, 2007 (6:39 am)
Replying to: anxs (Oct 30, 2007 7:17 am) Has anyone else noticed a wobbly or bumpy feeling while driving the cx-7? I test drove 2 different 2008 cx-7 sports both were front wheel drive. Only diff was one had a power seat and the other didnt. The car without the power seat drove a lot rougher than the car with the power seat. Is it possible that it is just my imagination?

Replying to: apatt (Dec 03, 2007 6:39 am) The only way you can tell if it's NOT your imagination is if you drove both vehicles over the exactly the same route, same driving conditions, same speed, traffic conditions, etc. The presence or lack of an accessory, does not make a difference in suspension, drive train or engine, in the FWD sport.   What I'm thinking is that you may have actually stumbled onto a problem, peculiar to that that one unit. Recommend you go to another dealer and test drive another vehicle and see if you notice the same problem.   Vince.

Replying to: anxs (Oct 30, 2007 7:17 am) anxs. I am having the same problem with the vibrations from the Bose. For me it is mainly coming from the door armrests, both driver and passenger. Right by the window controls. I upgraded to the Bose for the same reason and now it drives me nuts listening to the vibrating, which isn't quiet by the way, but really loud! Dealership said that there was nothing they could do about it. If anyone else hase run into this problem, let me know, and if there are any fixes I'm all ears.

Replying to: morrison0880 (Dec 11, 2007 2:06 pm) I have the tech package as well. It's not your imagination and there is a fix, but don't expect Mazda to do anything about. My dealership tried to fix it, but couldn't. It's the material in the door panels, which vibrates at low frequencies, such as strong bass. In my ride, when the doors were closed, the low frequency vibration was barely noticeable. But if the doors are open and I crank up the volume, the vibration in the door panels was horrible!   The fix is to go to an audio dealer and get DYNAMAT installed. I did and it makes a huge difference. Got rid of 90% of the vibration and also provides a measure of sound insulation from the exterior road noise. Cost me about $300 for both front doors, where all the vibration was coming from. Audio shop told me that they could do the entire car for about $700, which I'm considering.   Hope that helps! Vince.

Replying to: vbbuilt (Dec 11, 2007 3:56 pm) There is a little annoying rattle in the door, that I'm going to have checked out, but the vibrations I'm hearing with the stereo aren't coming from inside the door, but rather from the plastic moulding by the window controls. I can physically push in the moulding, and when I do the vibrations lessen, since I'm tightening the contact between the two plastic pieces, but don't entirely go away. The arm rest for your elbow near the back of the piece is made out of cushioned rubber and that area doesn't vibrate at all. I don't know why they didn't manufacture the entire top of the piece out of this rubber, or at least put a piece between the plastic components to dampen the vibrations. Probably has something to do with cost, but for such a small piece, that doesn't make sense for the cost of the vehicle. This is the first new car that I've bought, and although the rest of the vehicle is outstanding, this minor problem is a major disappointment. Takes away a lot of the fun of driving it, and I'm not sure anything can be done about it. I sent Mazda a nasty email, and I bet I get back some automated response. "Thank you for your feedback. We value our customers and their opinions. BUY THE NEW CX-9, SUV OF THE CENTURY!!!!" Replies to this message: dmele426 (Jan 14, 2008 10:08 pm) jjvan (Feb 04, 2008 12:11 pm)
#14 of 27 HELP, please! Vibrations at 30 AND 60?!? by kkearney Dec 29, 2007 (2:32 pm)
OK, here goes: 2007 GT. Bought 2nd hand from dealer with 12k miles, now have 26k. Since purchase have had a vibration I can feel through the steering wheel at almost exactly at 30 mph, lasting a few seconds, then dissapearing.   I've replaced the tires, which helped with handling, but the vibration remains. Once the tires were replaced I now get a shaking from ~58 to 62mph, which also dispappears. At all other speeds (up to 100) the car is solid - no shaking...   I return to the dealership figuring the tires are slightly off-balance... BUT, am told they are dead-on. When I ask about both vibrations I'm told that this is inherent in the car itself due to a short wheelbase, yada yada yada. Further, he explains that mine rides like a Cadillac compared to others in their inventory and that the '08's are worse! Now, I've owned a number of small cars including a Ford Fiesta (yikes), Accords, and a VW GTI. NONE (including the Fiesta) shook like this one...   So, my questions to the group are: 1) does anyone else feel a momentary vibration in the steering wheel at ~30mph? 2) How about vibrations and shaking in general? Have you had any you can't seem to get rid of? 3) How has your dealer been to work with? Is it time for me to find another dealer to look at this?   You help/feedback is appreciated.

Replying to: morrison0880 (Dec 12, 2007 6:03 am) I owna 2008 cx-7 awd-GT, I had the car for about 6 weeks (1500 miles later) and the car has developed a rattle or squeek as if some panel is loose within the passanger cabin / front right side. I cannot figure what it is?? anybody has the same problem, I can hear the noise specially over bumpy roads, i am heading out to the dealership in NYC-Long Island area to see if they can find the source. Anybody has any idea what it could be, worst yet i am afraid they may not even know what it is. Replies to this message: jjvan (Feb 04, 2008 12:11 pm)

Replying to: zewie1 (Aug 24, 2007 12:58 pm) That is what mine does. I call it a metal clanging rat-i tat-tat sound and then black smoke blows out the back only when accelerating and at any speed and never once tripped the CEL either. I have several posts on this website about it. I also have an extremely strong turbo lag which has put me in life threatening situations. Mazda told me it was not predetonation ping (it never even sounded like that anyway) and they didn't know what it was so they "red lined" my vehicle and notified Mazda to find a fix for it. That was October.   Very rarely, I am able to duplicate the problem and thank heavens a technician finally drove with me and witnessed it and it was just minutes after it occurred on the way home from work. Next time it does it pay attention to what you are doing. Mine happened quite often after a new tank of gas but not always and I could be going 45 or faster . . . it's ridiculous.   So a couple of days ago I contacted a lemon law attorney and they say I have a good case since I have been complaining about this since the first few months I owned the car and Mazda hasn't found a fix for it. I'll know the results in about 30 days. Needless to say, I've parked the car in the driveway and am not to drive it another mile till it's resolved.   It truly saddens me because I love the way this car looks and when it's not lagging or making that noise with the smoke it's truly a fun car to drive. And, If this case works I'm not even sure what I want. Dare I stay with Mazda and choose the CX9 .. . not sure. I've owned Toyotas forever and never had a single problem. I realize that the 2007 CX7 is new technology and maybe that was my mistake. .. the bugs hadn't been worked out yet.   Good luck on your noise issue. I sympathize with you.

Replying to: dmele426 (Jan 14, 2008 10:08 pm) How did you make out with your noise morrison0880 ? I have a 2007 cx-7 and have the same noise, on the same side, since I bought the car. It seems to start when I drive over 60 mph. It sounds like it comes from the door panel, but Im thinking its comming from the roof rack slots above the window. They do make alot of noise when you tap on them. I had the dealership look at it a few times, and they don't know where its comming from. All they say is that its wind related. I don't want to mess around too much and make even more rattles, so I just drive with the radio on when I drive over 60.
