Piston: Recalls
Vehicles Involved, Owner and Part Information
MODELS AFFECTED:
CERTAIN 1989-91 BUICK REGALS WITH 3.1L ENGINE (VIN CODE T)
CONDITION
General Motors has determined that some 1989-91 Buick Regal model vehicles built with 3.1L engines, may develop a condition of premature wear of
the pistons due to low adhesion of the tin plating. Evidence of this condition would be a cold engine knocking noise at low ambient temperatures. This
condition will not lead to engine failure and is typically limited to cylinders # 2, # 4, and # 6.
VEHICLES INVOLVED
Involved are certain 1989-91 Buick Regal model vehicles built with 3.1L engine (VIN Code T); RPO LHO within the breakpoints:
SPECIAL POLICY ADJUSTMENT
This special policy covers the condition described above on vehicles in specific cold climate states for a period of six years or 72,000 miles, whichever
occurs first, from the date the vehicle was originally placed in service, regardless of ownership. If piston replacement is required due to this condition, an
engine replacement should be made at no charge to the owner rather than replacement of individual pistons. This Special Policy Adjustment applies
ONLY to repair required as a RESULT of the described condition; it does not cover other conditions which may necessitate a partial engine replacement.
This "Special Policy Adjustment Bulletin" should be filed in your "Special Policy Adjustment Bulletins" binder furnished to dealers by General Motors.
OWNER NOTIFICATION
Owners in specific cold climate states will be notified of this special policy on their vehicle by Buick Motor Division (see copy of the owner letter
