What's wrong?
The brake pedal linkage on the 2017-2018 Polaris Slingshot connects the pedal you press to the brake master cylinder. The master cylinder is the hydraulic part that turns pedal movement into brake-fluid pressure, so the connection between the pedal and cylinder has to stay locked together.
On affected Slingshot motorcycles, the pin and clip that join the brake pedal to the master cylinder clevis were installed without full engagement. The clevis is the forked bracket on the master cylinder that holds the pedal linkage. If the clip and pin work loose, the pedal separates from the master cylinder and no longer moves the hydraulic brake system as designed.
This problem gives little useful warning. If a Slingshot was built with the condition, the driver is not expected to notice it until the pedal disconnects from the master cylinder.
Who's affected?
Both model years list the same hydraulic brake system, so the VIN check is the practical separator for owners.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
If the brake pedal separates from the brake master cylinder, the vehicle loses braking ability and crash risk increases. There is no warning sign before the pedal disconnects, so drive cautiously and schedule the inspection soon. Repair is free at any franchised Polaris dealer.
What should I do?
- Check your VIN to confirm your 2017-2018 Polaris Slingshot is included in this recall.
- Contact a franchised Polaris dealer to schedule the free brake-pedal retaining-clip inspection and reassembly that keeps the brake pedal connected to the brake master cylinder.
- Bring the recall notice if Polaris sent one. If not, reference recall number 18V321 when you call.
- Drive cautiously until the dealer has completed the inspection, and leave extra stopping distance.
What happens at the repair
At the dealer, a Polaris technician inspects the brake pedal retaining clip to confirm it is engaged correctly. If the clip is not seated as it should be, the technician reassembles the brake pedal connection to the brake master cylinder. The inspection and any needed reassembly are free under the recall. Polaris has a general reimbursement plan on file for related repairs paid before the recall notice. Bring repair paperwork and proof of payment to the service desk, or contact Polaris customer service to start the claim.
