Service bulletin N192268180
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Emissions Recall. 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.

| N192268181 | 2020-11-30. Service bulletin. Emissions Recall. 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 performance capability of the vehicle?s catalytic converters may have degraded, such that efficiency is reduced. In addition, the oxygen sensors may provide inaccurate information to the engine control module which manages engine combustion air-fuel ratios. If these conditions occur, 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 both catalytic converters and both oxygen sensors. |
