Can happen to any OEM and does...
Guessing that in these automated assembly lines that one of the tools
went out of calibration for a while till their 'normal' QC checks found
that torque setting was off
In taking this level of control away from the 'person' on the line...they
have introduced a 'blindness' to the system
Generally, the 'repeatability' of this kind of thing is way better with
a machine than a human. As the human has good days along with some bad
days...
Again, that then introduces a 'blindness' to the system and is the bad
day for the machine...
Similar to the local tire dealerships, including warehouses like Costco,
where the min wage installer is NOT allowed to use the torque wrench
on the lug nuts. Only a supervisor or someone approved by management
is allowed. Even then, noticed that their torque wrenches are tossed
around like a box wrench (it's a precision instrument and that messes
up it's calibration)
