Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the
dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in
this bulletin. This could be done by mailing to such customers a copy of the appropriate divisional customer letter accompanying this bulletin. Campaign
follow up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this campaign enters your vehicle inventory, or is in your dealership for service in the future, please take the
steps necessary to be sure the campaign correction has been made before selling or releasing the vehicle.

Owner Letter
June, 1996
Dear Pontiac Bonneville Customer:
This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.
REASON FOR THIS RECALL
General Motors has decided that a defect which relates to motor vehicle safety exists in the vehicle engine control system of certain 1996 Pontiac
Bonneville model vehicles equipped with a 3.8L V6 engine (RPO L36). These vehicles may exhibit, under a certain set of complex conditions, a backfire
during engine starting that can cause breakage of the upper intake manifold. This can cause a no start condition and possibly an engine compartment fire.
Also, if a person was in the immediate vicinity of the intake manifold when the hood was open, and this backfire occurred, it could result in personal
injury.
