well the original reason we took the car in was b/c when its wet/icy out the car tires spin and the car loses power.
Not debating your problem, but what your decribing sounds like the normal operation of the Trac Control on most Saturns. I know mine (2002 LW300) came with full time traction control that chops power if one wheel starts spinning.
I personally hate it when i try to take off from a Stop sign or light and make a corner when it's wet and the power dies off cause 1 wheel spins. I know it's supposed to be a safety feature but it is dangerous to have happen when you in heavy traffic and are trying to make it across an intersection...
All I have to do is remember to turn off the Trac Control (by pusing the button on the dash) when i turn on the car....
Now the dealer taking it home and crashing it, thats a whole nother story that possibly needs lawyer involvment....
