I am having trouble trying to finish the "Lair of the Shadow Broker" in the Mass Effect Trilogy on the PS3. I am up to the part of chasing down Vasir in the transports, where you have to hold down the L1 button to chase her down. Well, without warning, the controller just shuts itself off after holding the L1 button for a few seconds, which causes the vehicle in the the game to just stop or spin in circles. I did buy the game system with said controller pre-owned, but I don't know if that may be the issue, because it works fine with my other games, although I'm not holding the L1 button down that much when I am playing them.
How can I fix this?
