Buick regularly sends its dealers useful service bulletins
about Buick products. Buick monitors product
performance in the field. We then prepare bulletins for
servicing
our products better. Now, you can get these
bulletins
too.
Bulletins cover various subjects. Some pertain to the
proper use and care of your vehicle. Some describe
costly repairs. Others describe inexpensive repairs
which,
if done on time with the latest parts, may avoid
future costly repairs. Some bulletins tell a technician
how to repair a new
or unexpected condition. Others
describe a quicker way
to fix your vehicle. They can
help a technician service your vehicle better.
Most bulletins apply to conditions affecting
a small
number of cars or trucks. Your Buick dealer or a
qualified technician may have
to determine if a specific
bulletin applies to your vehicle.
You can subscribe to all Buick bulletins. This way you’ll
get them as they come
out. You can wait a while and get
an index to the bulletins.
You can also get individual
bulletins. However, you’ll need the index to identify
them.
