The front door windows no longer work. Most recently, the drivers side back door will not open. The lock is completely jammed - will not open or shut, which is a safety hazard for my child. The plastic parts in this car are failing and putting my family at risk.

2 Electrical System problem

Failure Date: 12/31/2018

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.

While driving on interstate 77, north bound, at 55mph, other motorists informed me that my car was on fire underneath.

I pulled over to the side of the road, the fire department and sheriff's office put out the fire and the car was towed. The car is quite new and with very low mileage. Well maintained car. No recent work other than regular oil change. Mazda denies any problems with this car.
