Certain vehicles may have rear bumper flanges that were manually bent after chrome plating. This bending could cause micro-cracking of the chrome plating and ultimately result in red rust forming on the base steel bumper. Dealers are to inspect for rust with step pad in place and apply wax if no rust is present. If rust is present with step pad in place, replace the chrome bumper.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10159552-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10159552-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10159552","components":[{"id":"structure-body","name":"Body and frame","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"CHEVROLET","model":"SILVERADO 1500","year_from":2019,"year_to":2019,"match":"base","vehicle_ids":["2019_chevrolet_silverado"]},{"make":"GMC","model":"SIERRA 1500","year_from":2019,"year_to":2019,"match":"base","vehicle_ids":["2019_gmc_sierra"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
