Service bulletin N192226060
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.

| N192273600-01 | 2020-04-20. Service bulletin. Emissions - General Motors has decided to conduct a voluntary emissions recall involving certain 2016-2019 model year Chevrolet Volt vehicles. The evaporative emissions pipe that connects to the inlet of the purge valve may rub against an air conditioning hose connector causing the pipe to chafe. Over time, such chafing can cause a small hole in the evaporative emissions pipe. If this were to occur, the evaporative emission system small leak detected Diagnostic Trouble Code (DTC P0442) would set and the Malfunction Indicator Lamp (check engine light) would illuminate. Inspect the evaporative emissions purge pipe for wear, secure a bumper on the pipe, and if necessary, replace the purge pipe. |
