Jayco PRECEPT problems and owner complaints

SINCE JUNE, 2016, MY BRAND NEW JAYCO PRECEPT 31UL MOTORHOME HAS BEEN AT THE MANTECA RV DEALERSHIP WHILE MULTIPLE ISSUES ARE BEING ADDRESSED. WHEN DRIVING IT, THE RV CONSTANTLY WANDERED ON THE ROAD LANE, REQUIRING CONSTANT CORRECTION TO KEEP IT TRACKING IN A STRAIGHT LINE. THE DANGEROUS PROBLEM WITH STEERING WAS REFERRED TO AN ALIGNMENT SHOP IN MANTECA. THE RECOMMENDED FIX WAS REPAIR OF THE CAMBERS. THIS HAS RESULTED IN THE STEERING WHEEL NOW OUT OF PLACE. THIS STEERING WHEEL PROBLEM WAS DISCUSSED FORD, THE MANUFACTURER OF THE CHASSIS, AS JAYCO …

Gears in steering gear box must be "sloppy". Constantly needing to correct to drive a straight line down the road. I have gone to "Safety Plus Steering Control" and had them install the proper Control arm, thinking this would solve the problem. It has not. The constant correcting of the steering going down the road is tiring. I believe the gearbox is the problem. This has been a problem ever since I bought it new in 2020, and is getting worse. Thank you

I purchased this 2026 Jayco Precept 34G Class A motorhome new in May 2026. During the first approximately 1,000 miles, it exhibited severe steering/handling instability requiring constant correction at highway speeds. As a first-time Class A owner, I initially thought this might be normal and continued operating it with family aboard. On XXX, a Ford commercial service center inspected the motorhome and documented missing steering-stabilizer hardware, specifically a missing nut, and a bent stabilizer shock. The service center photographed the de…

After filling our motorhome with fuel and driving on a trip, we noticed a check engine light that came on. I noticed a smell of gas but couldn’t pin point where it was coming from at that time. We ordered a code reader and it showed a large EVAP leak code which seemed to be there for a while but looked like it was cleared previously. Could still smell gas, so husband went under motorhome and smell got worse. Saw fuel leaking from filler hose that goes into fuel tank and no clamps in this particular area that was leaking fuel.
