What's wrong?
The 2021 Heartland Mallard uses a liquid propane hose and connector to carry LP gas from the trailer's propane system to appliances that need fuel. That hose has to stay clear of moving suspension parts. The suspension shackle is a metal link that moves as the trailer rides over bumps and the axle shifts under load.
On affected Mallard travel trailers, the LP hose and connector were routed too close to that shackle during installation. As the suspension moves, the shackle contacts the hose or connector. That contact can rub, pinch, or damage the propane line, which lets LP gas escape instead of staying inside the system.
Owners can notice a loss of LP gas or the smell of propane outside the RV. That odor is the warning sign that the propane system is leaking and the hose needs attention before the trailer is used again.

Not every 2021 Heartland Mallard trailer is on the list. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
LP hose contact with the shackle can damage the hose early, allowing LP gas to escape and increasing fire risk near an ignition source. If you smell LP gas outside the RV, shut off the propane supply, keep ignition sources away, and arrange service. Repair will be free at any franchised Heartland dealer once available.
What should I do?
- Check your VIN to confirm your 2021 Heartland Mallard is included in this recall.
- Keep the owner notice Heartland mailed on October 9, 2020, and use it when asking about the repair.
- Contact a franchised Heartland dealer and reference recall number 20V486 when you ask about the free LP hose relocation.
- Schedule the hose relocation if the dealer confirms it is open for your VIN; the repair moves the LP hose and connector away from the suspension shackle.
- Avoid ignition sources near the trailer until the hose position is checked and the repair is complete.
What happens at the repair
At the dealer, a Heartland technician relocates the liquid propane hose and connector so they cannot contact the suspension shackle. That moves the propane line away from the part that can rub or damage it during suspension movement. Confirm repair availability with the dealer before taking the trailer in. The dealer repair will be free once Heartland opens it, with parts and labor covered under the recall.

Frequently asked questions
What is recall 20V486?
Recall 20V486 covers 204 2021 Heartland Mallard travel trailers where the LP hose and connector can touch the suspension shackle. That contact can cause early LP hose failure and increase fire risk near an ignition source. Heartland dealers will relocate the hose for free.
What should I do if my 2021 Heartland Mallard is on this recall?
Check your VIN to confirm your specific travel trailer is included in recall 20V486. If it is, contact a franchised Heartland dealer to schedule the LP hose relocation. Reference recall 20V486 when you call. The dealer repair is free.
Is the recall repair free?
Yes. Federal recall law requires manufacturers to repair safety defects at no cost, and Heartland's remedy says dealers will relocate the LP hose to stop it from reaching the suspension shackle. Parts and labor are covered at a franchised Heartland dealer.
What is the safety risk?
The safety risk is fire. In recall 20V486, the LP hose and connector can contact the suspension shackle, causing premature hose failure. If propane escapes near an ignition source, fire risk increases. Confirm your VIN, then arrange the free dealer repair.
What if I bought the Heartland Mallard used?
