Owners/service Manual Problems of Mazda CX9

One day, my keyless don stopped working. The next day the door kept locking while I was driving almost every time I turned the steering wheel. Then the drivers door wouldn't unlock, when I manually unlocked the door it was hard to do. I luckily had the windows rolled down, got out the vehicle and as soon as I shut the door I hear the door lock and my two year old was in the backseat! again luckily I had the windows rolled down otherwise she might've been stuck! then the alarm kept going off and wouldn't turn off until I unhooked the battery. Imagine my frustration. I brought the car to a Mazda dealership who said it was the door latch/actuator. Upon paying heftily when I picked up my car, the clicking of the door locks had stopped but the unlock button still wouldn't work and the alarm was once again going off! now the car is still at the Mazda dealership and had its bcm/bcu replaced for a supposed �fix�, I'm suppose to pick it up tomorrow. So I guess we'll see. The apparent problem from all of this? my Cx9 has a sunroof, which Mazda knows these vehicles don't drain properly which causes water to go to the bcm shorting it out! this is inexcusable and could very well cost someone's child their life because of the doors constant locking and unable to unlock sometimes manually. The dealership has seen it on more than one occasion and Mazda company has even admitted this fault! so why is there no recall?!.

I was about to leave from my residential parking lot. I went to check my wheelchair was secure. I opened the liftgate. After securing the wheelchair I pressed the electronic button to close the liftgate. I heard 3 beeps, but the door/liftgate would not close. I turned the car off and on, I got out the manual began to try several things to close the door/liftgate. I locked and unlocked the door locks, I checked nothing blocking the sensors. I used the power control button under the dashboard and the door still would not close. I did this for an hour. Finally, something happened & was able to close the door/liftgate by hand. I took the car to a reputable machanic. They found "Mazda" had a "TSB" out about the liftgate lock assembly and if the lock fails, replace the entire part. I took the car to a Mazda dealer. The cost to special order the part and repair would cost approx. $1200. I can not afford to replace the lock. I I am a hadicapped person. I use mobility devices to help me remain mobile and get to and from doctors and therapy. . I cannot transport these devices( wheelchair, electric skooter/chair) because of the liftgate lock problem. I'm fearful the assembly will lock permanently and effect the door locks. Please, please assist me so the liftgate can be repaired. Thank you.
