OMB Control No.: 2127-0004 Part 573 Safety Recall Report 22V-871 The information contained in this report was submitted pursuant to 49 CFR §573 Manufacturer Name : Marion Body Works Inc. Submission Date : NOV 23, 2022 NHTSA Recall No. : 22V-871 Manufacturer Recall No. : 22V-778 Manufacturer Information : Manufacturer Name : Marion Body Works Inc. Address : 211 West Ramsdell St. Marion WI 54950 Company phone : 715-754-5261 Population : Number of potentially involved : 6 Estimated percentage with defect : 100 % Vehicle Information : Vehicle 1 : 2021-2023 Spartan Fire Gladiator, MetroStar, FC-94 and KME Panther Vehicle Type : BUSES, MEDIUM & HEAVY VEHICLES Body Style : OTHER Power Train : DIESEL Descriptive Information : The emergency response cab chassis affected by this recall are equipped with a Meritor axle using suspect tie rod clamps supplied to Meritor between December 16, 2021 and May 16, 2022. Refer to Meritor recall 22E-085. Meritor supplied axle Serial Numbers that were traced to the affected cab chassis. Production Dates : JAN 27, 2022 – SEP 26, 2022 VIN Range 1 : Begin : 4S9AV2D94MC560706 End : 4S9CU2D95NC560128 ✔ Not sequential Description of Defect : Description of the Defect : Based upon information provided by Meritor’s supplier, due to a heat treat issue, Meritor has determined that a population of tie rod clamps used in the manufacture of the subject axle population may be susceptible to cracking. Over time, a crack may lead to a complete fracture of the clamp, thereby reducing clamp load to the tie rod end. If both clamps on the tie rod were to fail, the cross tube could start to unscrew, vehicle alignment issues would evolve, and there is a potential for the tie rod end to separate from the cross tube. Separation is more likely to occur when tie rod loads are highest, which is at slow vehicle speeds over rough terrain or turning maneuvers. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : : Separation of the tie rod end from the cross tube could result in partial loss of vehicle steering capability, increasing the risk of a crash Description of the Cause : Excessive carbon caused by a damaged control board on one of four furnaces at the supplier. Part 573 Safety Recall Report 22V-871 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 Identification of Any Warning that can Occur : The initial effect would be a vehicle out of alignment. If both clamps on the tie rod cracked, the tube could rotate and result in a partial loss of steering capability. Involved Components : Component Name 1 : Tie Rod Assembly Component Description : Tie Rod Clamp Component Part Number : Unknown Supplier Identification : Component Manufacturer Name : Meritor Address : 22021 Skyway Church Rd Maxton North Carolina 28364 Country : United States Chronology : Refer to NHTSA Recall 22E-085 for the Meritor chronology. On September 15, 2022 – Spartan Fire received communication from Meritor of a steering arm clamp issue. An investigation was started and a potential population identified. October 3 – 14, 2022 – Spartan Fire received communication from Meritor about recall 22E-085. A final population is still being identified with Meritor. Stop ship issued within Spartan Fire. Escalated the issue to REV Group Management. October 14, 2022 – REV’s senior leadership approved a voluntary recall for this issue. October 19, 2022 – Meritor provided Spartan a final serial number list affected. Spartan determined final population. November 22, 2022 – Marion Body Works was notified of the affected population. Part 573 Safety Recall Report 22V-871 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 Description of Remedy : Description of Remedy Program : Meritor will work with affected vehicle manufacturers to replace suspect tie rod clamps on the subject axles. The vehicles that have been remedied would have been covered through the normal warranty process. How Remedy Component Differs from Recalled Component : Replacement tie rod clamps will meet Meritor’s specifications for heat treatment. Identify How/When Recall Condition was Corrected in Production : The sub-supplier to Meritor’s tier 1 supplier introduced metallurgical evaluation for excessive carburization for all heat treatment batches and an alarm was installed to alert operator if any deviating conditions occur. The correction was completed 5/11/2022. Recall Schedule : Description of Recall Schedule : Marion to begin dealer and customer notification by week of November 28, 2022. Planned Dealer Notification Date : NOV 28, 2022 – NOV 28, 2022 Planned Owner Notification Date : NOV 28, 2022 – NOV 30, 2022 * NR – Not Reported

December 13, 2022 Important Safety Recall Information – Recall Number: 22V-871 Affected Chassis: Dear Valued Customer, This notice is sent to you in accordance with the requirements of the National Traffic and Mortor Vehicle Safety Act. Spartan Fire, LLC has decided that a defect which relates to motor vehicle safety exists in certain model year 2021-2023, Gladiator, MetroStar, FC-94, and KME Panther model emergency response chassis cabs. What is the concern? Based upon information provided by Meritor’s supplier, due to a heat treat issue, Meritor has determined that a population of tie rod clamps used in the manufacture of the subject axle population may be susceptible to cracking. Over time, a crack may lead to a complete fracture of the clamp, thereby reducing clamp load to the tie rod end. If both clamps on the tie rod were to fail, the cross tube could start to unscrew, vehicle alignment issues would evolve, and there is a potential for the tie rod end to separate from the cross tube. Separation is more likely to occur when tie rod loads are highest, which is at slow vehicle speeds over rough terrain or turning maneuvers. This defect could result in separation of the tie rod end from the cross tube and could result in partial loss of vehicle steering capability, increasing the risk of a crash. The initial effect would be a vehicle out of alignment. If both clamps on the tie rod cracked, the tube could rotate and result in a partial loss of steering capability. Corrective Action Contact Meritor’s OnTrac Technical Call Center @1-866-668-7221 to open a case and order parts to complete remedy. There is no cost to the vehicle owner for the recall remedy. Meritor will work with affected vehicle manufacturers to replace suspect tie rod clamps on the subject axles. The affected emergency response chassis cabs are still within their warranty period and would not be subject to reimbursement. Meritor is providing, free of charge, the necessary components to rectify the issue and will pay labor costs for replacing the included components that have not already been replaced during normal maintenance. The repair will take approximately 1.25 hours to complete. Complete the work per Meritor’s instructions in the service bulletin. What should you do? Listed on this document, you will find the chassis cabs Marion has sold to you. If you agree the identified chassis, contains a safety defect, you are reminded of your responsibility to notify the National Highway Traffic Safety Administration (NHTSA) in accordance with 49CFR573. It is a violation of federal regulation to sell a vehicle subject to a safety recall without the recall first being remedied. Please contact Meritor’s OnTrac Technical Call Center @1-866-668-7221 to open a case and order parts to complete remedy at no charge to you or our mutual customer. Please submit any invoices with Meritor.
