What 2017 Jayco Seneca owners say
Most recent owner complaints, unedited.
Issue 1. RV plumbing system poorly designed and installed allowing Grey-water tank damage and unsafe and unsanitary sewage leak. The Grey-water tank was not engineered with close enough tolerance in the mounting structure to prevent shifting during normal driving conditions allowing the tank to uncouple from the mounting rails, breaking the plumbing fixtures and allowing sewage to spill in the plumbing compartment. The tank was also engineered without a support structure under the tank as a supplemental support. The authorized dealer diagnostic inspection and estimate of repair supports the lack of engineering standards. Issue 2. The on-board generator system fuel lines are routed over the top of the chassis lead-acid batteries. This is not logical, safe or prudent. In a collision, a battery short could cause a catastrophic fuel-fed fire.
