What's wrong?
The break away switch on a 2017 Jayco Fifth Wheel Seismic or Seismic Wave trailer is a safety switch tied to the trailer brake system. If the trailer separates from the tow vehicle, the switch is supposed to close an electrical circuit so battery power activates the hydraulic trailer brakes.
On these trailers, the switch was not wired according to Jayco's wiring print. The missing 12 gauge wire leaves the break away switch without the intended connection to the fuse. That means the hydraulic brakes do not receive the signal they need from the switch when the trailer separates.
There is no warning sign before failure. The trailer can tow normally because the problem is in the emergency break away wiring, so an owner is not expected to notice a sound, light, or change in brake feel before the switch is needed.

A matching 2017 Jayco Fifth Wheel Seismic or Seismic Wave does not guarantee inclusion. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
If the trailer separates from the tow vehicle, improper break away switch wiring can keep the fifth wheel brakes from applying automatically. That raises crash risk because the trailer will not brake itself after separation. Confirm your VIN and schedule the wiring correction soon. Repair is free at any franchised Jayco Fifth Wheel dealer.
What should I do?
- Check your VIN to confirm your 2017 Jayco Fifth Wheel Seismic Wave or Seismic is included in this recall.
- Contact a franchised Jayco Fifth Wheel dealer to schedule the free break away switch wiring correction, so the fifth-wheel brakes apply if the trailer separates from the tow vehicle.
- Bring the recall notice if Jayco has mailed one. Reference recall number 17V066 and Jayco recall 9901344 when you call.
- Keep the trailer parked until the wiring repair is complete, or ask the dealer for towing guidance before moving it.
What happens at the repair
At the dealer, a Jayco Fifth Wheel technician corrects the breakaway switch wiring for the hydraulic brake system, then confirms the emergency breakaway circuit is connected as intended. The recall repair is free, with parts and labor covered. Jayco has a general reimbursement plan on file for eligible out-of-pocket repairs paid before the recall notice. If you already paid for breakaway switch or brake wiring work tied to this defect, bring documentation to the service desk and ask Jayco customer service about reimbursement.
