This is a Quality Bulletin. Volvo Car USA LLC and Volvo Car Canada LTD (Volvo) on behalf of Volvo Car Corporation, has decided to launch Service Campaign S29846 on certain model year 2016 XC90 vehicles. Volvo has identified that engine coolant may leak due to an insufficient quick connector in the coolant expansion tank bleeder hose. Should this condition occur, a message in the Driver Information Module (DIM) will appear informing the driver about low coolant level and in a worse case situation high engine temperature. The corrective action is to replace the coolant expansion tank bleeder hose.
