One complaint can name several systems, so shares can add to more than 100 percent.
Confidence is the model's own probability for the label it chose (0 to 1), not accuracy.
Model-generated labels on tagged complaints only. Model years 2013 and newer are tagged in full; 2012 in part (see tagged_share); earlier model years have no tags. NHTSA's own flags remain separate in the complaints block.
Defect: Heartland Recreational Vehicles, LLC. (Heartland) is recalling certain 2018-2021 Mallard, Shadow Cruiser, Sundance XLTTT, Wilderness, Prowler, Trail Runner, 2018-2019 Pioneer, Terry Classic, 2020-2021 Lithium, and 2021 North Trail trailers equipped with a Winntec model 6020 two-stage propane regulator. The regulator may fail, causing an increase in propane pressure.
Consequence: Increased propane pressure can enlarge the flames in gas appliances, increasing the risk of a fire.
Remedy: Dealers will replace the regulator and test the propane system for leaks, free of charge. Owner notification letters were mailed August 3, 2021. Owners may contact Heartland customer service at 1-877-262-8032.
Defect: 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.
Do not drive: No. Park outside: No.

Notes on this record
Complaints from the API and bulk file are merged and deduplicated by ODI number; the API alone misses records.
System and subsystem counts are numbers of distinct complaints, recalls or communications that name them. One record can name several systems, so shares across systems can add to more than 100 percent; a single share never exceeds 100 percent.
Recalls are counted once per campaign, investigations once per action and manufacturer communications once per NHTSA id, even when NHTSA lists several model names for the same record.
A sales denominator is a calendar-year proxy, not the population of vehicles still in use. Rates are copied from verified pipeline output.
