On December 15, 2017, Shyft determined a noncompliance to exist in the affected units. On Wednesday October 12, 2022 sent to notice to Shyft (formerly Spartan) its petition has been denied. On October 19, 2021 engineering identified affected design codes from the previous recalled chassis were not made obsolete and began to investigated if those codes were used in other builds. On October 21 a potential list of VIN’s was identified. The locations of the affected chassis were evaluated and on 11/10 reconciled the recall population needed to be expanded. Part 573 Safety Recall Report 22V-785 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 Description of Remedy : Description of Remedy Program : Shyft will exchange one air reservoir with one with larger air capacity. Shyft is reviewing its plan for reimbursement. How Remedy Component Differs from Recalled Component : Vehicles affected by this condition would be equipped with a 500 cubic inch capacity air reservoir for the wet tank. A wet tank with 1000 cubic inches of air capacity would be installed in its place. Identify How/When Recall Condition was Corrected in Production : The recall condition will be corrected in production on, or after, 10/20/2022 by using an air tank reservoir with a capacity of 1000 cubic inches for the wet tank. Recall Schedule : Description of Recall Schedule : Shyft does not have dealers for this product line. Planned Dealer Notification Date : NR – NR Planned Owner Notification Date : NOV 18, 2022 – NOV 18, 2022 * NR – Not Reported

OMB Control No.: 2127-0004 Part 573 Safety Recall Report 22V-785 The information contained in this report was submitted pursuant to 49 CFR §573 Manufacturer Name : Shyft Group Submission Date : NOV 10, 2022 NHTSA Recall No. : 22V-785 Manufacturer Recall No. : 22-14 Manufacturer Information : Manufacturer Name : Shyft Group Address : 1541 Reynolds Road Charlotte MI 48813 Company phone : 517-543-6400 Population : Number of potentially involved : 540 Estimated percentage with defect : 100 % Vehicle Information : Vehicle 1 : 2015-2023 Spartan RV Chassis MM and K2 Vehicle Type : BUSES, MEDIUM & HEAVY VEHICLES Body Style : OTHER Power Train : DIESEL Descriptive Information : Motor home chassis affected by this recall are equipped with T24 brake chambers on the steer axle, T30 brake chambers on the drive axle, T16 brake chambers on the steer axle and a 500 cubic inch reservoir (Wet Tank) Production Dates : FEB 12, 2014 – AUG 30, 2022 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : The combined volume of air in all service and supply reservoirs does not meet the 12X combined volume for all service brake chambers as defined in S5.1.2.1 of FMVSS 121 – Air Brake Systems FMVSS 1 : 121 – Air brake systems FMVSS 2 : NR Description of the Safety Risk : In increased braking events, there may be inadequate air volume for the service brakes which may lead to other unintended consequences that could increase the risk of a crash. Description of the Cause : Pending Identification of Any Warning that can Occur : A low air pressure tell tale may illuminate, in addition to an audible alarm, in the event air pressure falls below a certain threshold. Involved Components : Part 573 Safety Recall Report 22V-785 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 Component Name 1 : Air tank Component Description : Air reservoir Component Part Number : NR Supplier Identification : Component Manufacturer Name : NR Address : NR NR Country : NR Chronology : On, or near, December 8, 2017, Engineering reviewed certain configurations of axles with certain brake chambers and performs capacity calculations on those axles. Engineering consults with Compliance on the preliminary findings. December 12, 2017, Compliance completes review of the requirements in FMVSS 121 for air reservoir capacity and performs calculation to confirm Engineering’s findings. A VIN list identifying motor home chassis that could be affected by this condition and a stop ship was placed on further shipments until the condition was remedied. Information regarding the actual capacity of the brake chambers was sought. On 12/13/17, the actual capacity of the service brake chambers was reviewed and it was determined the calculated amount of capacity was lower than the actual.
