What's wrong?
The ground cable on the 2016-2017 Volvo Bus 9700 with I-Start is part of the electrical return path. It gives current a solid path back to the chassis so the starting and power-feed circuits have stable electrical contact. The power feed relay depends on that contact to keep power flowing where the bus needs it.
On affected buses, the ground was installed in the wrong location. That position can leave the cable with poor electrical contact instead of a firm connection. Poor contact can overload or interrupt the K918 power feed relay, causing the relay to fail. If that happens while the bus is moving, the engine can stall.
There is no warning sign before failure. The Volvo Bus filing says there are no warnings, so a driver should not count on a light, sound, or rough-running condition before the relay fails.
Who's affected?
Both model years are tied to the same wiring component.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
An unexpected engine shutdown can leave the driver with reduced control and less time to respond, which increases the risk of a crash. There is no warning sign before shutdown. Drive cautiously and schedule the inspection and ground wire correction soon. Repair is free at any franchised Volvo Bus dealer.
What should I do?
- Check your VIN to confirm your 2016-2017 Volvo Bus 9700 is included in this recall.
- Contact a franchised Volvo Bus dealer to schedule the free ground-wire inspection and correction that protects the power feed relay from failure.
- Ask the dealer about prior recall 16V836 and tell them this recall requires additional repair under recall number 17V173.
- Bring the recall notice if Volvo Bus mailed one, or give the dealer recall number 17V173 when you schedule.
- Operate with caution until the repair is complete, and remove the bus from service if the engine stalls.
What happens at the repair
At the dealer, a Volvo Bus technician inspects the ground wire installation for the power feed relay circuit. The technician corrects the ground wire location as needed so the relay has proper electrical contact. The inspection and repair are free under recall 17V173. If you already paid for this ground wire repair before the owner notice, Volvo Group's standard reimbursement plan covers documented expenses. Bring repair paperwork to the service desk and ask how to submit it under that plan.
