GMV22

It's a 2001 LS 430, which took off like a rocket, speeding out of control immediately after I let up on the brake after putting the car in drive. The brakes didn't work either, and I ended up in a ditch. Someone could have been killed.

Anybody had an experience with their car accelerating suddenly and unintentionally? My car surged forward without me touching the accelerator, and I was wondering what the problem could be.
