What this recall means for you

A ground cable on certain 2016-2017 transit buses equipped with the I-Start feature may have been installed improperly, leading to poor electrical contact. This can cause the power feed relay to fail and the engine to stall.

An unexpected engine shutdown increases the risk of a crash. Owners of affected buses should be aware that these vehicles were previously repaired for a similar issue under an earlier recall, but this recall requires additional work to make sure the power feed relay will not fail.

The repair is free. Dealers will inspect the vehicle and correct the ground wire installation as needed. Owners will be notified by the manufacturer, and can contact Volvo Bus customer service at 1-877-773-8678 (recall number SR17-80).
