Well, whereas my first polite message to Buick went unanswered, my second
one did get a response.

The customer service person was gracious, if typically 'politically
correct'.

This is the answer I received:


Dear Mr. ***,

Thank you for contacting Buick again. We apologize for any inconvenience to
you. General Motors has and will continue to manufacture safe vehicles that
meet or exceed all federal regulatory requirements and our own stringent
internal safety requirements in performance and vehicle features. For
changes and updates to the 3800 Series engines, please check with your local
dealer.

To contact your local dealership's Service Department directly, you may
utilize the GM BuyPower web site to locate the participating dealership
nearest to you. Please go to www.gmbuypower.com and select "Locate Dealer"
under the Power Tools section. You will then be prompted to enter the
division and a city and state or zip code. This will locate the five
nearest dealerships in the area that you have requested. You may choose the
dealer you would like to contact by clicking on the name of the dealer.

We hope that this information answers your questions. If you need
additional information or have further questions, please let us know via
email or by calling Buick at 1-800-422-8425, between 8:00 AM-11:00 PM
Eastern Time, seven days a week. Again, thank you for contacting Buick!

Sincerely,

Ann **********

The dealership shop foreman simply answered that there had been 'no recall
issued on these (earlier) engines'.
