general problems of the 2011 Mazda CX9

Our vehicle has water drains or "weep" lines for the sunroof. We recently had the electrical system stop/start, dash lights remain on constantly after sitting in the driveway during the rain. We learned that if the drains become blocked that water leaks into the cabin directly onto the body control module (bcm). Because the bcm is not in a sealed or water-proof case, yet is soaked in these conditions, the vehicle is subject to electrical failure as a result. Replacing the bcm costs about $1,000. When we started the car the dash lights that warn of an issue with many of the vehicles safety systems remained on. Others went off and soft of flashed. We could not determine if there was really an issue with all of the components flashing on the dash so we did not want to drive it for fear of an accident. Our vehicle was stationary (thank god). We waited for a while and were able to leave for home, but this condition is clearly a huge safety risk.
