2012 Jayco SenecaBody, doors & structure

Serial Number 7C1HH0109 - Super C cab-over/front-cap-to-coach joint separation, fastener or attachment failures, and associated fiberglass damage. Significant separation has become visibly evident where the Freightliner cab connects to the coach. Where the cab-over section joins the main coach body the full vertical seams on both sides have separated with some areas exceeding 1 inch in depth of separation. The entire vertical seem is now separated showing exposed screw threads, and apparently vacant or damaged...

fastener holes with few connection points remaining. The horizontal seam on both sides is also visibly separating with fiberglass cracking stemming in multiple directions from the horizontal connection points. These conditions raise concern about possible loosening or failure of the attachment system and further separation during travel, potentially endangering occupants and other motorists. A qualified engineering inspection is needed to determine the cause, structural integrity, and safety of continued operation. Our RV has only 24,117 miles and was not involved in a collision and mileage was primarily highway miles to entertain at football tailgates and horseshows. The visible separation became evident in Sept 2026. Prior separation was masked by seams sealed with sealants that the sun has aged making the separation now visible. The cab over section has significant fiberglass cracking and damage from the related movement. Several photos I took in Sept 2026 demonstrate: - The open vertical body joint with visible joint separation extending the entire vertical seam - Exposed/displaced fasteners and vacant/damaged fastening locations - The overall cab-over/coach geometry showing pressure points evenly distributed both horizontally and vertically on both the passenger and driver sides. - Cracking and joint openings around the cab-over/coach transitions with substantial fiberglass cracking Jayco notified and replied looking into this with no progress

2023 Jayco SenecaFuel systemFire

It appears that the propane furnace broke loose from the vehicle frame and fell into the frame area of the RV. This was used for less than an hour where the vented heat started to burn the RV. I noticed afterwards when I went to check on something else the damage. I feel pretty confident that had I not turned it off, it would have resulted in possible fatalities, since the furnace was just underneath the bed slide. As you can see from the pictures the furnace broke loose from the frame and was no longer attached...

directly on either the sides or top. Additionally, there is a crack in the hard plastic case that contains the furnace, possibly where it is attached to frame as well. I have included pictures and have an appointment with a Jayco repair facility. I did speak with the Jayco manufacturing representative in Middlebury, IN. After reviewing my pictures and consultation with his bosses the gentlemen I spoke with told me not to bring it to them, that a Jayco repair facility near me will fix it, it is a warranty item. They also assigned me a case number: [[redacted]]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2023 Jayco SenecaEquipment & accessories

Improper mounting of the Dometic Water Heater by Jayco caused compartment failure. Jayco did not install supports under the 10-gallon water heater tank as required by Dometic (see installation instructions attached). Road bumps and vibrations caused the moment arm of the unsupported tank to tear the sheet metal water heater mounting frame fastened to the RV outer wall thereby causing a safety issue. The water heater compartment failed thereby tilting back behind the wall of the RV. When tilted back, the unit...

exhaust can enter the living quarters. When tilted back, the LP gas line is exposed to failure; the water line can break and there could be electrical implications. Other RV owners have described the same issue (see Inf from Amazon Review attached). Jayco customer service states they will do nothing unless directed by the NHTSA via a recall. They will not allow me to escalate the issue to Jayco management. I have an extended warranty and comprehensive insurance. Claims were discussed with both companies including photos but they reject this as a claim stating that a compartment failure is not covered even with safety concerns.

2020 Jayco SenecaBody, doors & structure

The fasteners for the front cap on the motorhome have failed and the front cap is separating from the body of the coach. Safety is an issue because a part of the vehicle is separating from the rest of the coach. We have contacted the dealer where our motorhome was purchased and pictures have been taken. We will be making arrangements for repair with Camping World in Golden, CO. The warning is the sight of the cover on both sides of the unit; the cover is separating from the coach and curling back. Our...

motorhome is low mileage (18,000 miles and a five year old vehicle). It has been housed in covered storage when not being used so weather and sun have not been a factor. January, 2025 we noticed the problem.

2019 Jayco SenecaBody, doors & structure

The seems on the can where the truck frame and RV frame come together were needing additional support and in my case support as there was no attempt from side to side swaying on the vertical seems. I had to bolt through the vertical seems with bolts and a piece of metal. Construction had to be done and done by me since I bought the coach used. I also had to reinforce the water tank as it was just sitting on plastic. This plastic was sitting on top of the wiring harness for the truck. It was also sitting on the propane line for the water heater. Could have resulted in a fire. Again since I bought the coach used and dealership told me to go pound sand.
