if that was true then your gyro was defective or there was a bug in your code reading the gryo value. Solid state gyros are highly reliable, the same AD chips used on the robots are used in cars for things like airbags and stability control (steering).

One thing about the gyros, they must be solidly mounted to the chassis of the robot. If the gyro can wiggle and vibrate (if you hold it down with tie wraps, or foam tape) you will get all sorts junk on the output signal.

To be useful the gyro chip must move exactly the same as the robot chassis moves.
