    Never had that issue but have seen many clogged drains for sunroofs. There is no manual on how to clean them, the focus is on keeping them clean. So try to not park under trees and when you wash your car, open up the sunroof and clean the rails and the surrounding area.

    well took it to dealership today. It was not the fuse, which I knew. Apparently the car has 2 horns. Both horns must have short circuited. I'm guessing from when the body control module went bad. So they are ordering new ones and will replace hopefully in the next day or so.

    So now hopefully this is it for awhile. I asked them when the parts come in to please check out the rest of the electrical on the car. I don't need anymore problems. Will see what happens.

    I had the same electrical issue symptoms, but all symptoms happened within 3-4 days. According to the dealer, the cause was water damage to the Body Control Module (BCM) caused by clogged sunroof drains.

    Anyone knows how?

    Thank you

    Folks -- Just have been noticing when turning down a steep hill from an uphill grade -- the TCS kicks in and hold the car back. Almost like a rubbing effect until the car straightens out. Dealer said nothing is rubbing, no computer faults. The dealer could not replicate -- we were fortunate to have the service tech come to our home so we can show him what happens -- He has saw but cannot duplicate it. Has anyone heard of this or know of a TCS update or problems. This is very frustrating on a extremely reliable car (so far)

    Thanks

    davicho - since you have seen many clogged sunroof drains, do you know what happens to the water overflow once the drain is clogged?
    From my understanding, the water drains into the roof /headliner section and flows down the windshield side supports and sometimes into the dashboard and behind the cabin walls. The BPM is located behind the driver's left foot and in my case, right into the overflow of water.

    Can you confirm if my understanding is correct. thanks

    Exactly what happened to your CX-9 is what happens. Since the water does not drain properly through the tubes and outside the vehicle, the water accumulates and eventually either seeps into the headliner or somewhere behind the dashboard as in your case where it can cause electrical damage to whatever component happens to be in its path. Clogged sunroof drain tubes and clogged A/C evaporator drain tubes are the major cause of water damamged electrical components inside the cabin as well as water damaged carpets.

    The main cause of clogged drain tubes (at least from what I have been exposed to here in a dealership setting) is lack of or unproperly cleaned areas around the perimeter of the sunroof (when open). Also helps to not park underneath trees that tend to drop lots of leaves, pine needles, debris, etc.

    Well today I have new problems. I think I will be checking into the lemon law. It rained alot last night. I woke up this morning with the TCS light on, the BSM light on and the traction control light on again. This after I already had the BCM module replaced 2 months ago. This is ridiculous. If it is because of rain in the moonroof like someone said then I would say the car has a defect.

    Is the Electrical problem still present in 2010 model or only in 2008 model? Is 2010 model reliable overall?
  • davichodavicho Posts: 190
    It is not a matter of the problem being present in certain model years. This problem was a one off that came about a clogged drain tube. The tube could have gotten clogged either while in transit or while ownership and it can happen to any vehicle with a sunroof. CX-9 are very reliable overall.

    Well after only a month or so, they are again replacing the BCM module. Apparently due to water leak because of moonroof. This is the 3rd time of fixing this. I never even open my moonroof. I have had them in all my cars and never had a problem. Now lets hope my horns, locks, etc all work.
  • davichodavicho Posts: 190
    I am begining to think that you are getting faulty BCMs out of the box and not being damaged by water from the sunroof drains but rather from water damage from the storage warehouses or shipment.
  • tomhawk1tomhawk1 Posts: 12
    ok, well its starting to be a joke.

    They said the tubes were kinked which then ripped causing the link. They replaced the BCM again. Now I was driving home and my sensors on the mirrors are not working. They are turned on. I called and they are going to talk with a tech and call me back.
  • davichodavicho Posts: 190
    Honestly tomhawk, after you get this whole BCM thing resolved, since they already started this whole thing, you need to find another more capable dealership. Sounds like those techs /dealership are a bunch of parts replacers rather then actual technicians.

    We have the same issue on slow moderate turns on pavement with speeds under 20 mph. Does not matter if it is left or right, wet or dry, up or down but it is in the same curves most of the time (~60%).
    Was able to duplicate it once for the Mazda service department supervisor on their lot. He said he thought it was a TSC "feature' and that there was not parameters for changing the programming of the system (AKA They could not fix it.) and that Mazda the corporation would not do anything to fix it unless they were forced to. That was five months ago and it is at the dealer service department today getting the heated seat problem fixed, an oil change, and the grinding ("rubbing effect") problem looked into by the new Mazda service department supervisor. (Nine hours later they say they need to keep the car...)

    This could be a neat car if it were not for curves...

    Let me know if anyone has better luck with a fix for this "feature".

    Seriously, if your local Mazda dealer's master technician can't fix the problem, go to another one. Some master tech is better than others.

    davicho, i understand the sunroof drain tube clogged, but why is the BCM (& other electrical components) located where water drains as designed?

    This is clearly not a one-off issue and is a serious design issue.

    when I break, the car front wheels and steering shake and the steering wheel sometimes spin to the right. They first they shaved the disks, then changed it, but still the same. Any suggestions? Thank you!

    My keyless entry FOB was starting to act funny and intermittently not working unless I pulled it from my pocket and held it out. Yesterday, it just stopped working so I replaced the battery thinking it was the battery. I have already changed the battery once about 6 months ago and prior it worked for over a year. So, any ideas what the problem could be? I had to use the key yesterday...and I don't like it as I've gotten spoiled by just pressing the door handle and turning the ignition!! :confuse: Also, I pressed the exclamation mark (!) on the fob one time and it seemed to work but I guess I just got lucky that one time.

    Thanks in advance for any advise or insight.
