My car recently failed to start. After a jump start from aaa I managed to drive the vehicle home. The car again failed to start. I diagnosed the problem as a bad battery and after locating the battery under the rear seat I was horrified to find that there was already corrosion under and around the battery area. I found a hole in the bottom of the car. This is a dangerous situation since I had no previous indication of the problem and the leaking battery had obviously existed for some time. The aaa representative who replaced the battery, made by ac delco, suggested it is not uncommon for the battery to fail around the + connection. I think I was lucky not to experience acidic vapors inside the car. I was surprised to find that there is no drip tray under the battery which would have averted the corrosion to the vehicle under the seat area. Batteries, like other parts, fail (this was the original battery) but steps should be taken to prohibit the corrosion problem particularly in an area that is only inspected after the failure. Under the hood batteries are far more visible.

Delco battery that comes with the vehicle has two outlets with two broken terminals that leak, and the gas that leaks. It is stored under the back seat, which also stores all the electronic relays that will produce sparks and create a hazardous situation, possibly starting a fire.

Battery is mounted under passenger's side rear seat. Consumer feels this is unsafe because one must pull seat up to get to battery. Dealer has been contacted.
