While traveling downhill, overdrive off, jake brake on, brake applied, when transmission downshifted, heard loud bang and saw black pieces bounce off the road and up past driver's window. Stopped vehicle and found holes in fan shroud, coolant draining on road, hole in fiberglass hood, and black plastic object lodge into wire bundle on right side. Vehicle towed to repair shop where fan was found to have shed plastic outer ring and top sections of blades. Plastic pieces were scattered throughout the engine compartment and embedded in radiator, multiple holes in fan shroud, half dollar size hole and hand size web of fractures in the hood fiberglass. Repairs to date include replacement of radiator, fan and fan shroud, a radiator hose, wires inspected and repaired, the hood is still in dispute. Gm has paid for parts but insists I pay the labor. I suspect the fan was defective and/or the jake brake system/transmission downshifted improperly causing the fan to overspeed and disintegrate. I read the previous posted incident from may 2009 and recognize this is a related event. Gm mechanics have told me this has happened previously but it is rare. While this maybe the case the potential for serious damage/death and/or property damage is high considering the penetration of metals, fiberglass and hoses if one of the projectiles released had hit a brake line. Repair shop kept parts.

Recall number 08V209000 · Recall details
Equipment: recreational vehicle/trailer: lpg systems
- What is wrong
- Jayco is recalling 1,265 my 2005-2008 seneca '35gs' and my 2007-2008 greyhawk '33ds' and '32ss' motor homes. The conduit clamp on the copper liquid propane (lp) tube feeding the slide-0ut is incorrectly placed which may allow the copper tube to bend and possibly leak with the movement of the slide-out.
- Risk
- If the copper tube cracked, pressurized lp gas may escape into the compartment. This condition, if not addressed, may result in a fire, injury or death.
- Remedy
- Dealers will relocate the conduit clamp and add a rubber grommet to allow adhesion. The recall began on may 26, 2008. Owners may contact jayco at 1‑574‑825‑5861.
Recall number 08V207000 · Recall details
Trailer hitches
- What is wrong
- On certain motor homes, the distance from the rear cap to the hitch receiver encourages the use of longer ball mounts and/or extensions. The longer the ball mount and/or extensions used, the greater the forces that are applied to the fasteners that attach the hitch to the main chassis rails. These increased forces exceed the allowable forces permitted in the fasteners. When this happens, the fasteners may stretch, loosen, or break causing an unsafe towing condition or separation of the hitch from the motor home.
- Risk
- This could result in separation of the towed vehicle from the motor home which could result in a crash, injury or death.
- Remedy
- Dealers will replace all mounting hardware with hardware of a higher grade. The recall began on january 22, 2007. Owners may contact jayco at 1‑800‑283‑8267.
