On certain 2014 model year Cadillac CTS vehicles, equipped with a 3.6L twin-turbo engine (LF3), the engine control module wiring harness may rub on the metal edge of the alternator bracket or on a weld on the vehicle body rail. This condition could damage the wiring harness. If the wiring harness is damaged, the Check Engine Soon lamp will illuminate, the vehicle may display intermittent reduced engine power, or a fuse may blow and prevent the vehicle from starting. Dealers are to inspect and, if necessary, repair the wire harness. Dealers are to also install a new design alternator bracket and install a mastic patch over the weld on the vehicle body rail.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2015/MC-10134763-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2015/MC-10134763-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10134763","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"wiring","name":"Wiring and fuses","parent":"electrical"}],"codes":[],"topics":[],"vehicles":[{"make":"CADILLAC","model":"CTS","year_from":2014,"year_to":2014,"match":"exact","vehicle_ids":["2014_cadillac_cts"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
