Replying to: nissmazlover (Nov 30, 2007 8:39 am) 1. Does the "crunch" show up anytime when the weather is below 32F, or does the car have to be out all day/night and cold soaked to get the noise? We have an insulated garage that usually stays above freezing, but the car is parked outside all day in sometimes sub-freezing weather. 2. Are there specific times the your hear the crunch? I have seen speed bumps noted, but is it only over bumps or even during cornering or even backing out of the driveway? Since it is the wife's car, most of my driving has been short trips to the store from the above freezing garage. So far I haven't heard the crunch. I will ask her more about it as well, but I'm sure she would tell me about it. Also, I can look at the VIN plate for a date of Manufacture for anyone interested if it turns out we aren't hearing the crunch. |

Replying to: mrbwa1 (Nov 30, 2007 12:08 pm) My response: anytime the temperature falls to -10C or lower - that's when the rear end crunch occurs. If it falls below -20 to - 25C - and standing in an uninsulated parking garage all day- it soulds like the rear end is going to "break away" from the front end. 2. Are there specific times the your hear the crunch? I have seen speed bumps noted, but is it only over bumps or even during cornering or even backing out of the driveway? My response: The crunch can be heard by going over irregularities in the road - minor crunch if the temp. is -10C. Going over things like big bumps - speed bumps and railroad tracks at -10C it is much louder; though at -20 to -25C the noise is loud enough for others outside the vehicle to notice it - inside it was nerve -wracking in the beginning, and as the previous poster said you know it's coming so you don't get to out-of-joint about it. It is still embarassing to drive others in this vehicle with the crunching noise. I imagine they wonder why I put up with it, or why I bought it in the first place. If I drive the car for an hour or so, then the noise will lessen as the vehicle parts warm up, but that only happens in the milder cold weather, in the deep freeze, it is there always.BTW, your wife would certainly let you know if she was experiencing the same problem but it is interesting that she isn't. Does that mean that some vehicles have the poorly designed bushings, while other vehicles don't? Also what happens once the warranty runs out and the problem hasn't been resolved permanently? Now I have a question for you - does your wife's VIN fit within the range of the TSB that was issued?

Replying to: trishr1 (Nov 30, 2007 6:50 pm) We went out to dinner last night and I got to drive the 5 in the cold. It also set out for a couple our when we were out in 19F weather, so not quite to -10C and no ill effects. We may or may not see -25C, but not until Jan/Feb. I have talked to my wife and she reports no sounds at all. I looked up the TSB and checked the VIN plate on the care. I was a little surprised to see a build date of 11/06 (we bought in 11/07). It appears that a change may have been made sometime in the 2006 run. I see that the VINs in the TSB are: 111238 for bushings and 120197 for the Control arm. Ours ends with 141276. I guess all I can say is start shopping Mazda service. So far we've had pretty good luck with service... the dealership didn't do a walk-around, so our brand new 5 had a dent and had to go to the body shop! Our 2001 Toyota ECHO had basically the same issue with the front suspension and we lucked out with a service department that replaced the entire right front suspension, fixing the issue. Unfortunately, the warranty expired and now the left does it... I feel really bad for those who have the issue because it ruins such a nice car! |

Replying to: trishr1 (Nov 30, 2007 6:50 pm) 2. The crunch happens anytime it is very cold outside, moreso when it's 32 degrees or less. It is VERY noticeable over speed bumps, large road undulations, or large potholes. Also, if the driveway you are backing out of has a large incline, and you come out fast enough, it will crunch, as well. Minor potholes in the road will sometimes elicit smaller crunch noises, as well. But, after about 20 minutes or so of driving, the suspension seems to warm up and it doesn't make any noises, unless, of course, you go over a large speedbump at speed. The suspension has to articulate just enough for you to hear it well. If it's really cold, however, you don't really need to do much in order to hear it. Hope that helps answer your questions.

Hi suspension problem readers, After having the bushings changed in Nov 06 and the control arms replaced in March 07, we continued to have front and rear suspension noise in sub zero temps. I went to a different dealership (where we had had our initial sub-par buying experience) and after listening to the problem, they were happy to replace the bushings and controls arms again, claiming that the previous repairs may not have involved the updated suspension parts. So, two weeks ago we had it done and voila, it has a quiet ride again. It sounds like the new car it is (we have an 06 GT 5sp with 23k km) and makes it a pleasure to drive once more. The last time we had the bushings replaced, the noise reappeared after 2 months. The last control arm change didn't even score us one day of riding without noise. We will see how long the current 'fix' lasts. with crossed appendages, riproy

Replying to: riproy (Dec 18, 2007 9:58 am) I took mine in today for an oil change - a fix for the intermittent remote starter problem (yes there is a fix for that too), and "front" bushing replacements again (second time). The Service Manager had said a few weeks ago that they could only do the front bushings (but at that time the noise was from the rear only of my vehicle) so I called Mazda Canada to lodge a complaint about the rear noise. This must have been duly noted, because they replaced both the front and rear bushings today I noticed no noise on the short ride home, HOWEVER, there is a note of caution, it is mild out today, -5C, so this is not a true test, but it was nice to hear nothing but road noise  . Some people ,on other forums, can't really understand why there is such a fuss about a little squeak here and there. Those who complain about the "crunching noise" may have higher expectations or standards.  Anyway, I'm with you, and will cross anything that will help make it a permanent fix. |

Replying to: mdchachi (Dec 18, 2007 2:45 pm) Are you in a cool climate or cold climate? A colder climate might predict a more sustained crunch. Initially mine would crunch until it warmed up, but later on it crunched all the time. What year of vehicle - 2007 or 2008? Out of curiosity to those with squeaky, crunching vehicles regardless of model year - anyone's VIN start with "JP"?

Replying to: trishr1 (Dec 18, 2007 6:09 pm) Mine is a 2006. The previous owner said he did have some warranty work done regarding this issue but obviously it didn't take care of the problem. I'll check my VIN later. What does "JP" mean? I believe all Mazda 5's are made in Japan so if that's what it means, they should all have it.
