Official summary
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. Service Campaign S29846 affects 35,037 vehicles in the U.S. and 2,832 in Canada.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
