Issue: On certain travel trailers with the spare tire mounted on the bumper, the U-bolts that hold the spare tire carrier to the travel trailer may break. This could cause the tire and carrier to separate from the trailer. Safety Risk: A spare tire carrier that falls from the trailer could become a hazard for other road users and bystanders. This could create a risk of injury and/or a crash. Corrective Actions: Heartland RV will notify owners by mail and instruct you to take your travel trailer to a dealer to replace the defective U-bolts. Heartland RV advises that you should remove the spare tire until the recall repairs have been completed.
