except: with the consent of the vehicle owner or, if the
vehicle is leased, with the consent of the lessee; in
response to an official request of police or similar
government office; as part of GM’s defense of litigation
through the discovery process; or, as required by

for GM research needs or may be made available to
others for research purposes, where a need is shown
and the data is not tied to a specic vehicle or
vehicle owner.
