Volvo Car USA LLC and Volvo Car of Canada Ltd (Volvo) on behalf of Volvo Car Corporation, has decided to launch Service Action S29942 on certain model year 2019 XC40 vehicles. Volvo has identified that the catalytic converter diagnosis is not running as often as required. This condition does not affect vehicle drivability nor will it inhibit the OBDII system from monitoring, detecting and subsequently storing a corresponding diagnostic trouble code in system memory. Please note that there are no customer symptoms associated with this issue and vehicle drivability is not affected. The corrective action is to perform a total upgrade.
