9 month old travel trailer fridge caught fire upon startup this season. May4th
June 2023 from the inside of the RV we noticed the back end of the RV sagging. I inspected the frame and found it was broken in several places. The right side of the 'I' beam was cracked just above the rear leaf spring hanger. On the left side of the trailer the leaf spring hanger was broken off the 'I' beam and the 'I' beam was bent. This rendered the trailer extremely dangerous to pull. This trailer was purchased in 2019 and was not driven recklessly to cause this to happen. Just normal driving. The RV is available for inspection however it has been repaired, and the frame has been re-enforced with steel plates. The RV forum I am on indicated both the RV manufacture and the frame manufact…
Frame has broken in 2 locations at spring attachment bracket.
My Mallard 25 manufactured by Heartland was in the shop for another issue (black water tank). As they removed the under-belly, they noticed 4 cracks/fractures in the I-Beam on both sides behind all 4 wheels. The cracks vary in length. They told me to contact Heartland to see what can be done. I have done that and have received no response. I believe this is a dangerous driving condition and that NHTSA should be notified immediately. Kennedyâs RV technicians will confirm their findings through pictures. I also have copies of the pictures. Thank you in advance for your quick response.
They trailer hitch that I have used with this travel trailer has begun to fail. The head tilt spacers are beginning to elongate and will reach failure with continued use. The manufacturer indicated that this would be caused by overloading or a sharp turn, but neither of those events have happened. Luckily I caught the dialing part when I did, if the spacers would have failed the entire hitch could have failed. An internet search indicates that this premature failure is a known and common problem.

Camping World did a warranty axle repair in March 2021. During this repair, they mounted the axle but did not connect the electrics - I have pictures of coiled wires they left after mounting the new axle. This meant that the rear axle did not have the electric brakes, or the emergency breakaway disconnect. I had a electrician crimp the brakes during a trip in april 2021, after I discovered this. Since I'm not a technician, I did not know that the emergency breakaway also needed to be connected. It remains unconnected to this day. The emergency breakaway issue was discovered during a routine Virginia state safety inspection. The breakaway is related only to the rear axle, which was rep…

Repair instructions and other communications the manufacturer sent dealers about known issues. A TSB is not a recall, and the repair is usually free only while the car is under warranty; ask your dealer for the bulletin number.
Certain 2025 Heartland Mallard, Prowler, Eddie Bauer and Corterra Travel Trailers have fiberglass walls that are too short to adequately protect the floor decking. These instruction provide for the proper steps to add additional seal to the bottom of the sidewall to prevent any water intrusion.

In complaints filed with NHTSA for model years 2017–2025, owners most often name: equipment, suspension, electrical system. 16 complaints are on record.
No. A complaint is an unverified report from an owner. A technical service bulletin (TSB) is the manufacturer telling dealers how to fix a known issue; it is not a safety recall and is usually covered only under warranty. A recall is a formal safety action, and its repair is free.
File a vehicle safety complaint at NHTSA.gov. NHTSA reads every report, and patterns of complaints are what open defect investigations and, eventually, recalls.
