What's wrong?
The brake Hydraulic Electronic Control Unit on the 2017 Jayco Precept is part of the antilock brake system. It helps manage brake pressure when the system is balancing braking force or preventing wheel lockup during hard braking. Inside that unit, valve blocks route pressurized brake fluid where it needs to go.
On affected Precept motorhomes, the HECU valve block can be missing ball plugs. Those plugs seal passages inside the valve block. Without them, brake fluid can leak, or air can enter the hydraulic brake system when electronic brake distribution or ABS activates. Air in brake fluid changes how pressure moves through the system, so the brakes do not respond as designed.
The warning sign listed for this recall is the brake warning light illuminating. If that light comes on, treat it as a brake-system warning, not as a routine dashboard nuisance.

What's the safety risk?
A brake fluid leak or air in the brake system lengthens stopping distance and increases the risk of a crash. If the brake warning light comes on, pull over when it is safe and contact a dealer for repair guidance. Repair is free at any franchised Jayco dealer.
What should I do?
- Check your VIN to confirm your 2017 Jayco Precept is included in this recall.
- Contact Jayco customer service at 1-800-517-9137 to schedule the free brake HECU inspection and repair.
- Ask whether a Ford dealer will inspect the hydraulic block and replace the HECU if the ball plugs are present.
- Bring the recall notice if Jayco mailed one. If not, reference recall number 18V078 when you call.
- Drive cautiously until the repair is complete. Leave extra following distance because the brake fluid leak or air ingestion can lengthen stopping distance.
