Recall Campaign No.131 Brake Light Relay
Background:
Volvo Cars of North America, LLC and Volvo Cars of Canada, Ltd. have decided that a
defect related to motor vehicle safety exists in the rear left and right brake light relays of certain model year 2002 V70 and V70 XC (Cross Country) vehicles. In some cases, the
brake lights may not function when the brake pedal is depressed or may stay on
continuously. In both cases, the high positioned brake light and all other tail lights will
not be affected.
The corrective action will be to replace the brake relay with two relays of a modified
design.
