Hi-thanks for the info-I am not sure if there is a venting system. I am going to ask. The model is a 1999 c230??
The battery exploded from inside out and the liquid poured out of the car, underneath the car.
One of our biggest concerns is that if the battery exploded while driving do we have an on-going safety issue here...it was pretty scary..and just as important is the problems you described of future damage etc--it seems we will be forced to have a damaged car or sell it and take a huge $loss---
Do you think it would be fair to ask MB to warranty the problem?
