The implants have a major flaw in that extreme cold interferes with their functions and can disable them given sufficient exposure. However, when Austin returns to a warmer temperature, the implants quickly regain full functionality. The first season also established that Austin's bionics malfunction in the micro-gravity of space, though Austin's bionics are later modified to rectify this. The bionic eye is vulnerable to ultrasonic attack, resulting in blindness and dizziness. It is not explained how Austin's organic body is able to withstand the stress of either bionic hardware weight or performance of superhuman feats.
