What's wrong?
The axle, rims, and tires on a 2021 Heartland Mallard trailer carry the trailer's weight and keep the wheels aligned under load. The axle supports the trailer frame, the rims hold the tires, and the tires are the only parts touching the road. All three parts need matching size and load ratings so the suspension and tires share the work correctly.
On affected Mallard M180BH trailers, Heartland installed the smaller axle, rims, and tires used on a pilot build instead of the production parts with the correct ratings. The production change was not filed before assembly, so trailers left the plant with parts that did not match the intended specification. The correct service parts include a 5100 pound axle and ST225/75R15 tires, while the incorrect setup uses 205/75/14 tires.
The warning sign is visible, not a sound or warning light. Inspect the tire sidewall: if it reads 205/75/14, the trailer has the incorrect axle, rims, and tires installed.
Who's affected?

What's the safety risk?
Incorrect axles, rims, and tires can overload the trailer and increase the risk of a crash. Check the tire sidewall. If it shows size 205/75/14, treat the trailer as affected and schedule the repair before further use. Repair is free at any franchised Heartland dealer.
What should I do?
- Check your VIN to confirm your 2021 Heartland Mallard is included in this recall.

- Give the dealer recall number 21V009 when you call, and bring the recall notice if Heartland sent one.
- Tow cautiously until the repair. Keep cargo light and avoid loading the trailer near its rated capacity.
