Owner report 11474132 · 2022-07-15 (July 15, 2022)
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 emer…

Owner report 11532337 · 2023-07-14 (July 14, 2023)
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. Kennedy’s RV technicians will confirm their findings through pictures. I also have copies of the pictures. Thank …

Owner report 11608954 · 2024-08-16 (August 16, 2024)
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 …

18V634000 · Suspension:Rear:Axle:Non-Powered Axle Assembly
Reported: 2018-09-21 (September 21, 2018)
Heartland Recreational Vehicles, LLC (Heartland) is recalling certain 2019 Heartland Mallard, Pioneer, Sundance XLT, Wilderness, North Trail, Prowler and Trail Runner travel trailers. The axles may be missing inner bearing races on the hubs, which can cause the bearing to burnout or cause the hub to overheat.
Consequence: The missing bearing race may cause premature hub bearing failure, possibly resulting in a separation of the hub from the axle, thereby increasing the risk of a crash.
Remedy: Heartland will notify owners, and dealers will replace the defective hubs with new hubs or replace the axles, free of charge. The recall began October 9, 2018. Owners may contact Heartland customer service at 1-877-262-8032. Heartland's number for this recall is 99.01.40.
