What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2017 Jayco Seneca, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Body & structure
Reports naming the vehicle structure, frame, body panels, doors, hood and trim.
From owner reports, verbatim
The forward over cab section is separating from the primary house box because of extremely poor designed/engineered assembly process. The cheep screws used in production are breaking.
Too few reports in this category for a page of its own — they appear in the full complaint list.
Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
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.
Too few reports in this category for a page of its own — they appear in the full complaint list.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
