This bulletin applies to 2013 Buick Enclave vehicles. The SES light may be on with misfires and any of the following injector-related codes:

P0201, P0202, P0203, P0204, P0205, P0206, P0261, P0262, P0264, P0265, P0267, P0268, P0270, P0271, P0273, P0274, P0276, P0277, P2146, P2149, P2152, P2155, P216A and/or P216D.

Carefully inspect the fuel injector wiring harness for rub-through or internal wire opens. Some common spots are against the intake plenum, at valve cover bolts, against the fuel line and on the side of the head under the plenum.

If this concern is found, repair or replace the injector harness as needed.
