This is caused by a variable valve being stuck in the closed position. When returning from fast idle to normal, the stuck valve suddenly opens due to thermal change around it which causes abnormal noise. To eliminate this concern, the internal design of the exhaust manifold has been modified.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10222564-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10222564-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10222564","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"323","year_from":1998,"year_to":2001,"match":null,"vehicle_ids":[]},{"make":"MAZDA","model":"626","year_from":1998,"year_to":2002,"match":"exact","vehicle_ids":["1998_mazda_626","1999_mazda_626","2000_mazda_626","2001_mazda_626","2002_mazda_626"]},{"make":"MAZDA","model":"626","year_from":2003,"year_to":2003,"match":null,"vehicle_ids":[]},{"make":"MAZDA","model":"B-SERIES","year_from":2010,"year_to":2010,"match":"exact","vehicle_ids":["2010_mazda_b-series"]},{"make":"MAZDA","model":"B-SERIES TRUCK","year_from":1998,"year_to":2009,"match":"base","vehicle_ids":["1998_mazda_b-series","1999_mazda_b-series","2000_mazda_b-series","2001_mazda_b-series","2002_mazda_b-series","2003_mazda_b-series","2004_mazda_b-series","2005_mazda_b-series","2006_mazda_b-series","2007_mazda_b-series","2008_mazda_b-series","2009_mazda_b-series"]},{"make":"MAZDA","model":"CX-3","year_from":2014,"year_to":2014,"match":null,"vehicle_ids":[]},{"make":"MAZDA","model":"CX-3","year_from":2016,"year_to":2021,"match":"exact","vehicle_ids":["2016_mazda_cx-3","2017_mazda_cx-3","2018_mazda_cx-3","2019_mazda_cx-3","2020_mazda_cx-3","2021_mazda_cx-3"]},{"make":"MAZDA","model":"CX-30","year_from":2020,"year_to":2022,"match":"exact","vehicle_ids":["2020_mazda_cx-30","2021_mazda_cx-30","2022_mazda_cx-30"]},{"make":"MAZDA","model":"CX-5","year_from":2012,"year_to":2012,"match":null,"vehicle_ids":[]},{"make":"MAZDA","model":"CX-5","year_from":2013,"year_to":2020,"match":"exact","vehicle_ids":["2013_mazda_cx-5","2014_mazda_cx-5","2015_mazda_cx-5","2016_mazda_cx-5","2017_mazda_cx-5","2018_mazda_cx-5","2019_mazda_cx-5","2020_mazda_cx-5"]},{"make":"MAZDA","model":"CX-9","year_from":2016,"year_to":2020,"match":"exact","vehicle_ids":["2016_mazda_cx-9","2017_mazda_cx-9","2018_mazda_cx-9","2019_mazda_cx-9","2020_mazda_cx-9"]},{"make":"MAZDA","model":"MAZDA6","year_from":2017,"year_to":2020,"match":"exact","vehicle_ids":["2017_mazda_mazda6","2018_mazda_mazda6","2019_mazda_mazda6","2020_mazda_mazda6"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
