Buick 2013 Regal Owner's Manual page 396

If you believe that your vehicle
has a defect which could cause
a crash or could cause injury or
death, you should immediately
inform the National Highway
Traffic Safety Administration
(NHTSA) in addition to notifying
General Motors.
If NHTSA receives similar
complaints, it may open an
investigation, and if it finds that
a safety defect exists in a group
of vehicles, it may order a
recall and remedy campaign.
However, NHTSA cannot
become involved in individual
problems between you, your
dealer, or General Motors.
To contact NHTSA, you may
call the Vehicle Safety Hotline
toll-free at 1-888-327-4236
(TTY: 1-800-424-9153); go to
write to:
Administrator, NHTSA
1200 New Jersey Avenue, S.E.
Washington, D.C. 20590
