- Summary
- Some 2WD and 4WD pickup trucks, converted to either dedicated or bi-fuel compressed natural gas (CNG) fuel usage, were assembled with a throttle cable that can contact and rub through the flexible pressurized fuel line creating a pinhole leak of natural gas to the atmosphere.
- Consequence
- A strong odor of natural gas may be detected from inside the vehicle, possibly accompanied by a hissing noise. If the natural gas were accidentally ignited, serious injury could result.
- Remedy
- Dealers will secure the throttle cable to eliminate the possibility of contact with the CNG fuel line. The CNG fuel line, throttle cable, and cruise control cable are also to be inspected and replaced if necessary. Owner notification began on December 11, 2003. Owners should contact Chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463.
- Notes
- GM recall no. 03053.CUSTOMERS can contact the national highway traffic safety administration's auto safety hotline at 1-888-dash-2-dot (1-888-327-4236).

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.
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.
