It could be possible that during the engine assembly, one of 16 earth connectors was not torqued to the required specification resulting in an inconsistent electric connection. If one of these connectors is not tightened correctly the following problems may occur: l) MIL light would be activated, 2) failure to start the engine, 3) long term - oil pressure sensor damage.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10188994-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10188994-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10188994","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"ROLLS-ROYCE","model":"CULLINAN","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_rolls-royce_cullinan","2021_rolls-royce_cullinan"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
