General Motors has decided to conduct a voluntary emissions recall involving certain vehicles equipped with a 2.4L engine and certified to the EPA Bin 4 emission standard and the California Cleaner Federal Vehicle option of Bin 4 emission standard. The vehicle?s post-catalyst oxygen sensor may provide inaccurate information to the engine control module, which manages engine combustion air-fuel ratios. If this condition occurs, tail pipe emissions may exceed allowed limits, without providing any notification to the driver. The malfunction indicator lamp (check engine light) will not illuminate. Dealers are to replace the post-catalyst oxygen sensor.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10183214-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10183214-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10183214","components":[{"id":"engine","name":"Engine","parent":null},{"id":"exhaust-emissions","name":"Exhaust and emissions","parent":null},{"id":"exhaust-pipe","name":"Exhaust manifold, pipes and muffler","parent":"exhaust-emissions"}],"codes":[],"topics":[],"vehicles":[{"make":"CHEVROLET","model":"EQUINOX","year_from":2012,"year_to":2013,"match":"exact","vehicle_ids":["2012_chevrolet_equinox","2013_chevrolet_equinox"]},{"make":"GMC","model":"TERRAIN","year_from":2012,"year_to":2013,"match":"exact","vehicle_ids":["2012_gmc_terrain","2013_gmc_terrain"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
