Chronology :
On August 20, 2021 Trail King
was contacted by a customer that, during a routine inspection, had discovered cracking in the rear axle suspension slide pan of 3 of its 45 ACS trailers. The customer inspected the remaining 42 units and found cracks in 9 of the slide pans. Trail King
had not received similar reports of cracking on this trailer model from any other customer and based on Trail King
โs evaluation, it determined that the cracks observed in the trailers for this customer were due to a trailer application issue specifically with this customer.
On September 14, 2021, Trail King
was notified by a different customer of a similar issue with the performance of a slide pan. Trail King
confirmed the customerโs report with photographic evidence on October 6, 2021.
On October 8, 2021, Trail King
decided to conduct a recall.

Industries Inc., is submitting required information pertaining to our general reimbursement plan for the cost of remedies paid for by vehicle owners before they are notified of a related safety recall. Set forth below is Trail King
โs general plan to reimburse owners and purchasers for costs incurred for remedies in advance of notification of potential safety-related defects or noncompliance pursuant to Part573.6(c)(8)(i). Reimbursement Notification Trail King
โs notice to a vehicle owner in accordance with 49 C.F.R. Part 577 will indicate whether Trail King
is offering a refund. An owner will be eligible for reimbursement if the owner paid to have service to remedy the defect or noncompliance prior to a specified ending date. In accordance with Part 573.13(c)(2), the ending date shall be ten calendar days after the date on which Trail King
mailed the last of its Part 577 notifications to owners in the United States, unless a specific reimbursement plan is made available for a particular recall. Owners are instructed to seek eligible reimbursement though a Trail King

notes that in accordance with regulation, Trail King
may identify a beginning date for reimbursement eligibility. Under the rule, an owner who paid to remedy the defect or noncompliance prior to the identified beginning date would not be eligible for reimbursement. Trail King
generally has not established such a beginning date for reimbursement eligibility and does not presently anticipate changing this general policy. However, in any case where Trail King
determines that a beginning date is appropriate, Trail King
will indicate that date in the specific reimbursement plan for that particular recall. As permitted by Part 577.11(e), Trail King
may not include a reimbursement notification when all vehicles are well within the warranty period, subject to approval by the National Highway Traffic Safety Administration (โNHTSAโ). Costs to be Reimbursed For vehicles, reimbursement will not be less than the lesser of: Version 11.4.21 1. The amount paid by the owner for the remedy that specifically addressed and was reasonably necessary to correct the defect or noncompliance that is the subject of the recall; or 2.

For replacement equipment, reimbursement will be the amount paid by the owner for each replacement item (limited to the amount of the retail list price of each defective or noncompliant item that was replaced, plus taxes, where the brand or model purchased by the owner was different than the brand or model that was subject to the recall). If the item of motor vehicle equipment was repaired, the reimbursement provisions identified above for vehicles will apply. Trail King
