Turbo engine (L3B), may have a condition where the engine wiring harness could wear through in several locations. This may allow the engine harness to short to ground and/or be severed, which may lead to a check engine light, reduced engine power, no start condition or in rare cases a stall. Dealers are to wrap the wiring harness with Nylogard sleeve(s) in areas of concern.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10169647-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10169647-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10169647","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"engine","name":"Engine","parent":null},{"id":"turbocharger","name":"Turbocharger or supercharger","parent":"engine"}],"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.
