Summary: On certain trucks equipped with rpo IK9, due to insufficient durability and testing, the fuel switching manifold solenoids lack water or salt intrusion resistance, which can lead to failure of one or more solenoids. Fuel switching manifold solenoid failure will cause incorrect fuel delivery resulting in fuel overflow from the fuel filler neck.
Consequence: Overflow fuel may result in high amount of diesel fuel leakage. Fuel leakage, in the presence of an ignition source, could result in a fire.
Remedy: Dealers will replace the solenoid valve assembly with an improved assembly including additional detection circuit and enhanced water resistance free of charge. The recall began on October 27, 2005. Owners may contact Isuzu at 1-800-255-6727.
Notes: Recall no. 05053.CUSTOMERS may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to http://www.safercar.gov.

Has your Chevrolet been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Chevrolet dealer can also check your VIN. Recall repairs are free.
