Just remember on that trip--I'd expect you'd just take your wife for the anniversary trip, but if you do take any kids you have, and they're sitting in the 2nd row and complain of no leg room, tell 'em to move their own seat! hahaha.

Replying to: MazdaTechie (Aug 31, 2009 7:11 pm) Thanks for your warm welcome MazdaTechie. I have been lurking and I see that you are a Mazda Technician. I also work for a dealership (Auto Group) in the wholesale parts department but we do not work the Mazda brand, so I would say I am adequately technically inclined but not to a technician level. So I am sure that i will be bothering you with questions from time to time. Thanks again, and no...the boys will be staying with Grandma. It is only the wifee and I in our anniversary getaways! LOL!

Replying to: MazdaTechie (Aug 24, 2009 11:09 am) Yes, it is the blower fan I was referring to. I have the 100K warranty so I will take it back and mention the TSB. Thanks again.

Replying to: MazdaTechie (Feb 24, 2009 10:00 pm) God I hate to get inolved in "the noise" issue... but if you really prowl around on this forum and talk to other drivers - the right, front knocking noise at low speeds, over bumps seems to be extraordinarily consistent. Noises come in all different frequencies and volumes and can also be transmitted differently, so it's a tricky issue - always. BUT - the descriptions of this low frequency, non metallic knocking noise is very very consistent on all the forums - which leads me to believe that there really is a source for this noise. Do thousand and thousands of car owners have to go for a ride with the tech, for the noise to not appear, and then we just go on like this for years? The last time I heard a noise like this was from a Ford Explorer that kept eating up the front torsion bar bushings and spitting them out, bit by bit. It took Ford two years to come up with a solution, but once they did it was fixed properly. Where are we going with this clunk/knocking suspension noise issue? Strut tower bearings/brake booster plate/cv joints... WE NEED HELP! Thanks Replies to this message: MazdaTechie (Oct 26, 2009 6:52 pm)

Replying to: pwr1 (Oct 26, 2009 4:52 am) I believe you. By all means, I know in my heart you're telling 100% truth, and the noise is happening. However, consider a competent technician's point of view, whether it be mine or someone else's:   If you're experiencing an abnormal noise, whether it be this or something else, I as a technician simply MUST be able to hear the noise as well, and be able to hear it at least somewhat consistently. If it's intermittent and I have to drive for a little while or try different road qualities, or do something totally out of the ordinary to make it happen, that's fine. But if it doesn't happen at all, or only happens once, there is NOTHING for me to go by in order to fix it.   The sad truth is that sometimes, the problem has to get worse in order for me to track it down.   Example: A wonderful customer of mine has a 2006 Tribute. He's been experiencing a buzzing noise somewhere in the steering column. The first time he came in for it, we rode together and could not duplicate it. I explained to him in my typical fashion the same ideas I've expressed above. He understood. I took care of his other maintenance and issues on that visit, and sent him on his way. The next time he came in, he stated the noise had become more consistent. We rode again, and I, albeit faintly and intermittently, could hear it. But it was enough to begin the chase. After a day and a half of digging, turns out it was literally in the steering column itself--not anything attached to it, and nothing else transferring the noise into it.   The point is, I'm only able to troubleshoot a problem I can reproduce, and that goes the same for every technician out there. If you find an auto technician that promises to fix a problem he can't duplicate, except for VERY few exceptions, he's lying to you, or overconfident.   I say very few exceptions. These exceptions come in the form of Technical Service Bulletins (TSBs). In the case of a TSB, even then the manufacturer typically asks the technician to duplicate the problem first. But there are some where it will not be possible. For example, we've had issues with the occasional A/C freezing up on long trips. Mazda is aware that a technician cannot test drive the customer's vehicle in a "long trip" fashion to duplicate an A/C freeze-up. However they released a TSB to address the issue, and literally said to perform the repair based on the customer's description of the problem (but still stating 'if system operates normally').   I just searched for TSBs with the symptoms you described. The closest one refers to a low pitch squeak/chirp heard from the front suspension or dashboard, and instructs to replace the strut top mounting rubber on the offending side. However nothing came up for a knocking noise.   I know this reply is lengthy, but I'm hoping I can at least be clear. The truth is, rare/almost non-existent are the noises that never get worse with time and use of the vehicle. If you come in and you can't make the noise happen for the tech one time, just come in again when it gets more consistent, or on a day where it's just happening like crazy. In other words, KEEP TRYING, and any good, honest technician will KEEP TRYING WITH YOU. Every Mazda dealer technician has several resources (people and in print) at his disposal in addition to his skill to fix the issue if he can duplicate it. If you continue to come in, eventually (and if it's something serious, probably sooner than you think), you and the technician WILL be able to duplicate it, and he/she WILL be able to chase it down. As that time approaches, you'll also learn more and more on how to specifically duplicate it. Hot weather/cold weather, warmed up vehicle or dead cold first thing in the morning, the description you gave, etc. And the more specific descriptors you give, the better off you and the dealer will be. Your service advisor should be probing for details, but my advice to you is to provide them without being asked, and try to ensure he/she acknowledges you and notes them down. Not all service advisors will make the effort on their own, unfortunately.   Summary: No matter what the noise is, if it can't be reproduced on your service visit (be it driving it, revving the motor, hitting the area it's coming from, or whatever method works), there's no humanly possible way for a technician to even know where to begin to try to fix it, much less find the source of it. But if you work with the dealer (and in turn the technician) by returning again whenever you can make it happen best, or when it gets worse, or what have you, I/we/they WILL fix your car.   And if you come in during your warranty for the noise, but we can't reproduce it until your warranty has expired, I've seen it happen multiple times where that issue will still be honored under warranty simply because you experienced it during that time.   So please, don't lose hope.
