General Motors has decided to conduct a Voluntary Emission Recall on certain vehicles equipped with a 6.0L gasoline (L96) engine and dual fuel tanks (N2N). There is a potential that the rear fuel tank inlet check valve may have been damaged during vehicle assembly. If this condition exists it may be possible for fuel or fuel vapor to leak at the connection of the fuel filler hose to the rear fuel tank. Dealers are to replace the rear fuel tank.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10135167-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10135167-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10135167","components":[{"id":"fuel-system","name":"Fuel system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"CHEVROLET","model":"SILVERADO 2500","year_from":2018,"year_to":2018,"match":"base","vehicle_ids":["2018_chevrolet_silverado"]},{"make":"GMC","model":"SIERRA DENALI","year_from":2018,"year_to":2018,"match":"base","vehicle_ids":["2018_gmc_sierra"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
