What's wrong?
The turn signal flasher on the 2017 Zero S is the small electrical control unit that makes the turn signal lamps blink at a steady rate. It also has a second job: when a turn signal lamp fails, the flash rate is supposed to change enough to tell the rider that the signal is not working.
On affected motorcycles, an internal manufacturing defect in the flasher unit keeps that warning behavior from working as required. The signal lamp failure can happen first, but the flasher does not change its blink pattern in the required way. That leaves the rider without the normal visual cue that another road user is no longer seeing the intended turn signal.
What you notice is the problem itself: a turn signal lamp failure without a clear change in flash rate. If the signal stops working and the blink pattern looks normal, the flasher has failed to alert you.

What's the safety risk?
A failed turn signal can leave other drivers without clear notice before a turn, increasing the risk of a crash. The flasher can fail to give the required faster flash rate when a lamp fails, so inspect the signals before riding and schedule the recall repair soon. Repair is free at any franchised Zero dealer.
What should I do?
- Check your VIN to confirm your 2017 Zero S is included in this recall.
- Contact a franchised Zero dealer to schedule the free turn-signal flasher test and replacement, which fixes the missing fast-rate warning when a signal stops working.
- Bring the recall notice if Zero mailed one. If not, reference recall number 17V436 when you call.
- Check the turn signals before each ride and avoid riding until repair if a signal is not working.
What happens at the repair
At the dealer, a Zero technician tests the motorcycle's turn signal flasher. If the flasher does not alert the rider with the required change in flash rate, the technician replaces it. The recall repair is free, including parts and labor. Zero has a general reimbursement plan on file for owners who already paid for this flasher repair before the recall notice. Bring repair invoices or payment records to the service desk and ask how to submit the claim.
