Automatic Transmission problems of the 2004 Honda Element

2004 Honda Element: (I have 2 and both have the following exact problems)1. Airbags warning lights indicating problems 2. Drivers seat is loose and rocks 3. Passenger seat causes extreme discomfort to hip and back on long tips (this is occurs with all passengers, young and older) 3. Under carriage brushes failure 4. A/c air compressor failure 5. Straps in back seats pulled out and seat cannot be reclined 6. Engine decelerates without warning. Power cutback during passing makes this very dangerous. 7. Drivers seatbelt buckle is difficult to secure (only 1 car with this problem) 8. Loud clanking noise when cars are being turned.

My mother arrived at my home in her Element to pick up my children. She was going to drop off some items in the house while my children proceeded to get in the car to get in their car seats. The car rolled backward into the pond and the two children ages 3 and 6 (thank the lord) were rescued alive while the car quickly sank. When the car was pulled from the pond it was in neutral and the keys were on the floor. My complaint is twofold: my mother was able to shut off the car and remove the keys with the car in neutral. The gear shift on the floor does not have any visual indicator (a red line or an arrow) to indicate the gear the car is in. Once the car is shut off- the indicator on the dashboard would not have been lit. I believe that the eye-hand disconnect between the shifter on the floor and the indicators on the dash is a pitfall for user-error. Had she not been able to remove her keys with the car in neutral, it would have been clear to her that she had not parked the car correctly.

With vehicle in drive and with engine running, the car will roll backward down hill. My driveway has a small incline - vehicle rolls backward while in gear (drive) with engine running. 2004 Honda Element ex.
