Summer is here. There may be more people with this issue.
I did a complete report on edmund.com's forum (CX9 problem thread).
If you print it out and take it with you, your mechanic will not fool around.
The fix should be quick and easy. Good luck.
Here is a reprint of what I put there.
...........................................................................................................................
At 5400 miles, 1st problem showed up.
Last week, I tried to roll down the driver-side rear door window. It made a loud noise 1/2 down and continued to go all the way down. Tried it again (up and then down), no noise! Puzzled. So I tried the other side (still rear door window). It made the same loud noise. Tried a couple more times, it stuck at 2/3 and wouldn't roll down.
No problem rolling up, thought.
My gut feeling was that something in the window mechanism was loose on both sides (!together!).
So, today I took it in to Oak Tree Mazda in San Jose.
I explained and showed the problem to the service advisor (nice guy, friendly, too).
He got me a loaner (Mazda 3 sedan with 1400 miles on it! Nice!).
When I picked it up, both are fixed nicely.
Here is what they put down on the service record:
"Rt side: Styroform(foam) pads has completely fallen off and is blocking the glass. Reinstalled styroform pad using silicon rubber."
"Lt side: Styroform(foam) pads inside the door has failed off from summer heat on the double sided tape attaching the styroform. Reinstalled styroform pads but applied silicon rubber for added support." (word by word)
They even turned on the "autolock" feature of SmartKey for me for free.
All it costed me was 1 gallon of gas I had to put in the loaner Mazda 3.
Anyway, summer is here. I don't think I am the only one that has this issue.
It is also nice to know that Mazda give customers loaner for repair and major
service. I don't think I was ever treated like that from Honda or Toyota!
Sure, I am not happy with the material or workmanship that caused the failure of the windows. However, I am glad that Oak Tree Mazda treated me fairly.
I would recommend Oak Tree Mazda to anyone.
They will get a 5-star for satisfaction from me for sure.
