SEOCONTENT-START

4680 Pinson Valley Parkway, Birmingham, AL 35215 Office: 205.920.2499 Fax: 205.341.0375 General Recall Reimbursement Plan I. Introduction Pursuant to 49 U.S.C. 30120(d), 49 C.F.R. Parts 573 and 577, and other applicable requirements, Autocar, LLC and Autocar Industries, LLC (collectively “Autocar”) hereby provides the National Highway Traffic Safety Administration (“NHTSA”) its general reimbursement plan for the cost of remedies paid for by vehicle owners before they are notified of a related safety recall. As set forth at 49 C.F.R. 573.6(c)(8)(i) and 49 C.F.R 573.13, the following information sets forth Autocar’s general plan to reimburse owners and purchasers for costs incurred for remedies in advance of notification of potential safety-related defects or noncompliance. II. Reimbursement Notification Autocar’s notice to a vehicle owner in accordance with 49 C.F.R. Part 577 will indicate whether Autocar is offering a refund. A vehicle 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. As set forth at 49 C.F.R 573.13(c)(2), the ending date shall be 10 calendar days after the date on which Autocar 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. Autocar’s notice will instruct owners to seek eligible reimbursement through Autocar’s Service & Warranties Department, at the following address or otherwise applicable business address: Autocar LLC Service & Warranties Department 551 S. Washington Street Hagerstown, Indiana 47346 Owners will also be instructed that they may contact Autocar by telephone (toll free) at 888-218-3611 or 877-973-3486 NHTSA’s regulations (see 49 C.F.R. 573.13(c)) permit Autocar to identify a beginning date for reimbursement eligibility. Accordingly, an owner who paid to remedy the defect or noncompliance prior to the identified beginning date would not be eligible for reimbursement. Autocar puts its owners and customers first, and therefore, the company has generally has not firmly established such a beginning date for reimbursement eligibility, and as of the date of this policy, does not presently anticipate changing this general policy. Should Autocar determine (as NHTSA permits) that a beginning date is appropriate, Autocar will indicate that date in the specific reimbursement plan for that particular recall. As permitted by 49 C.F.R. 577.11(e), Autocar may not include a reimbursement notification when all vehicles are well within the warranty period, subject to approval by NHTSA. 4680 Pinson Valley Parkway, Birmingham, AL 35215 Office: 205.920.2499 Fax: 205.341.0375 III. Costs to be Reimbursed For vehicles, reimbursement will not be less than the lesser of: • 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, • The costs of the part(s) for the remedy (to be no more than the manufacturer’s list retail price for authorized part(s)), plus associated labor at local labor rates, miscellaneous fees (such as disposal of waste), and taxes. 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. As set forth at 49 C.F.R. 573.13(d)(1), costs incurred by the owner within the period during which Autocar’s original or extended warranty would have provided for a free repair of the defect or noncompliance will not be eligible for reimbursement. IV. Entity Authorized to Provide Reimbursement Autocar will directly reimburse owners, unless a specific reimbursement plan is made available for a particular recall, and will encourage owners to pursue requests for reimbursement directly through its Service & Warranties Department to expedite reimbursement, as set forth above in Section II. In whatever manner the request for reimbursement is made, under this Plan or a specific reimbursement plan, the owner will be directed to submit the required documentation, upon which reimbursement eligibility will be determined. V. Required Documentation The reimbursement determination will depend upon the information provided by the owner. As set forth at 49 C.F.R. Part 573.13(d)(4), the owner must submit all of the following information: • Claimant’s name and mailing address; • For motor vehicles, the vehicle identification number (or “VIN”), vehicle make, model, and model year; • For replacement equipment, a description of such equipment or, for tires, the model and size; • Identification of the applicable recall (either Autocar’s recall number, or NHTSA’s applicable recall campaign number); • Identification of the owner of the recalled vehicle at the time that the pre-notification remedy was obtained; 4680 Pinson Valley Parkway, Birmingham, AL 35215 Office: 205.920.2499 Fax: 205.341.0375 • An original receipt for the pre-notification remedy that includes a breakdown of the amount for parts, labor, other costs and taxes, including costs for the replacement item. Where the receipt covers work other than to address the recall or noncompliance, Autocar may require the claimant to separately identify costs that are eligible for reimbursement. • If the remedy was obtained during the warranty period, documentation indicating that the warranty was not honored or that the warranty repair did not correct the problem related to the recall. Failure to submit all of the above information may result in denial of the reimbursement request. VI. Additional Information The Part 577 required owner notice will provide a toll-free telephone number through which specific information about the reimbursement plan can be requested from Autocar. As set forth at 49 C.F.R. 573.6, this general reimbursement plan will be incorporated into notifications by reference. Information specific to a particular recall also may be incorporated into the Part 573.6 notification. VII. Response to Requests for Reimbursement Autocar will act upon requests for reimbursement as follows: • Autocar will act upon a claim for reimbursement within 60 days of its receipt. If Autocar denies the claim, Autocar will send a notice to the claimant within 60 days of receipt of the claim that includes a clear, concise statement of the reasons for the denial. • If a claim for reimbursement is incomplete when originally submitted, Autocar will advise the claimant within 60 days of receipt of the claim of the documentation that is needed and offer an opportunity to resubmit the claim with complete documentation. Reimbursement shall be in the form of a check from Autocar. VIII. Miscellaneous Autocar will make a copy of this plan available to the public, upon request. As permitted by 49 C.F.R. 573.13(m), Autocar will not reimburse owners for recalls based solely on noncompliant or defective labels. As set forth at 49 C.F.R. 573.13(n), reimbursement for a pre-notification remedy will not be provided to an owner if, in the case of a motor vehicle or replacement equipment other than a tire, it was bought by the first purchaser more than 15 calendar years before notice is given under 49 U.S.C. 30118(c) or an order is issued under section 49 U.S.C. 30118(b). In the case of a tire, this period shall be 5 calendar years. Dated: June 1, 2020

Contact your local fire department for guidance and additional compliance information. Technicians working on Autocar trucks with CNG or LNG engines must be trained in the proper repair of CNG and LNG trucks and engines and the safe storage and dispensing of CNG and LNG. Working on CNG Fuel Systems CNG fuel systems include a high pressure (3600 psi) system for fuel storage and a low pressure system (125 psi) for consumption by the engine. Understanding the characteristics of CNG and how the fuel system works will prevent injury and damage to persons and property. Attempting to operate or maintain any CNG fuel system without proper training is dangerous. Complete training and consult instructional bulletins from the CNG system suppliers, such as Agility Fuel Systems’ Field Service Bulletin, Safely Working on CNG Fuel Systems. Welding and Hot Work Near CNG and LNG Trucks Welding, grinding, and other “hot work” can be safely performed on or near a CNG or LNG vehicle, but certain precautions must be followed. Understand and perform the necessary precautions provided by the CNG system suppliers, such as Agility Fuel Systems’ Field Service Bulletin, Welding and Hot Work Precautions Near CNG and LNG Vehicles. Page 5 of 20 January, 2022 SAFETY RECALL BULLETIN NHTSA RECALL 21V930 AUTOCAR, LLC SAFETY RECALL ACX-2107 Autocar, LLC 4680 Pinson Valley Parkway Center Point, AL 35215 888-218-3611 CNG Cylinders CNG fuel containers must meet Federal Motor Vehicle Safety Standard (FMVSS) 304 (Compressed Natural Gas Fuel Container Integrity) and/or ANSI/CSA NGV2 (Basic Requirements for Compressed Natural Gas Vehicle Fuel Containers). Both standards specify a detailed visual examination every three years. Truck owners are required to complete all necessary inspections, in accordance with the applicable standards and other resources, such as the Clean Vehicle Education Foundation and NGVAmerica’s Compressed Natural Gas (CNG) Container Visual Inspection Advisory. FMVSS 304 also requires that cylinders not be used after the end of life (EOL) date provided on the tank label. The EOL date is also displayed in the engine compartment and at the fueling connection of each truck. If there are any question as to proper decommissioning of a cylinder, contact the manufacturer, whose name and address is also required to be on the label. CNG Fuel Container Pressure Relief Devices (PRDs) PRDs must be properly maintained and positioned for safe operation of a CNG fuel system. Missing vent caps can allow moisture into PRDs and vent lines, which can freeze and damage these safety components. Debris which clogs the PRDs and/or vent lines can prevent proper function. PRDs must be positioned to vent upward, not outward, from a vehicle. Ensure that every truck owner completes periodic inspections of the PRDs and vent lines and systems, in accordance with guidance provided by the system component suppliers. Alert First Responders to CNG and LNG In the event of a fire or other emergency, alert first responders to the presence and location of CNG fuel systems, tanks and dispensers. Ensure that emergency personnel are aware of proper precautions, such as those provided in Agility’s First Responder Guide: CNG and LNG Vehicle Fuel Systems.

OMB Control No.: 2127-0004 Part 573 Safety Recall Report 21V-930 The information contained in this report was submitted pursuant to 49 CFR §573 Manufacturer Name : Autocar, LLC Submission Date : NOV 26, 2021 NHTSA Recall No. : 21V-930 Manufacturer Recall No. : ACX-2107 Manufacturer Information : Manufacturer Name : Autocar, LLC Address : 551 S WASHINGTON STREET HAGERSTOWN IN 47346 Company phone : 7654895499 Population : Number of potentially involved : 16 Estimated percentage with defect : 100 % Vehicle Information : Vehicle 1 : 2020-2020 Autocar Xpeditor Vehicle Type : BUSES, MEDIUM & HEAVY VEHICLES Body Style : OTHER Power Train : NR Descriptive Information : Certain Xpeditor units that were custom built for a specific customer and have been up-fitted with an aftermarket power take off (PTO) may experience a stall/hesitation condition during launch with the PTO engaged. Production Dates : NOV 19, 2019 – NOV 25, 2019 VIN Range 1 : Begin : 5VCACSCEXLC232643 End : 5VCACSCE1LC232658 Not sequential Description of Defect : Description of the Defect : A potential stall/hesitation during launch when operated from the right sidestand up position with the hydraulic system engaged. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : When operated from the right side stand up position with the hydraulic system engaged, the vehicle could experience a stall/hesitation during launch. If this occurs while operating on an incline, the vehicle could move rearward, increasing the risk of a crash, personal injury or property damage. Description of the Cause : A considerable amount of the available engine torque at idle is consumed by the hydraulic system function. The right side stand up driver position does not readily allow for brake modulation. Identification of Any Warning that can Occur : None. Involved Components : Part 573 Safety Recall Report 21V-930 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 Component Name 1 : NR Component Description : NR Component Part Number : NR Supplier Identification : Component Manufacturer Name : NR Address : NR NR Country : NR Chronology : On or about February 5, 2020, Autocar received information regarding two CNG units and one diesel unit for certain vehicles that were custom built for one customer. The information provided indicated potential concerns in connection with a lack of acceleration. An internal corrective action was initiated to analyze the alleged condition. On or about February 6, 2020, additional information was added to the corrective action to additionally evaluate the sales order group of 48 units to the one customer, and Autocar’s field service team proceeded with its investigation. On or about February 12, 2020, the Autocar field service team preliminarily identified that the “Vehicle Accelerator Management” parameter was unexpectedly enabled on the diesel unit, and Autocar tentatively identified that the parameter had not been enabled by Autocar prior to first sale to the customer. When this feature was disabled, the reported concern was eliminated, and the customer returned the vehicle to service. Further analysis in or about mid-March 2020 confirmed Autocar’s February 2020 preliminary view that the accelerator management parameter was not enabled by Autocar. As a result, Autocar reasonably determined that this was an isolated incident. Autocar subsequently moved the diesel unit matter to a separate corrective action, and closed it as resolved. Between late March 2020 and June 2020, the COVID-19 global pandemic restricted Autocar’s reasonable ability to conduct its normal investigative process, including travel restrictions, mandatory shelter in place orders, and related government ordered restrictions. Despite these government ordered restrictions, Autocar was in full communication with the customer, and in good faith, Autocar did not reasonably assess the reported condition as an unreasonable risk to safety. On or about June 25, 2020, (Complete chronology will be attached as character limits were reached). Part 573 Safety Recall Report 21V-930 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 Description of Remedy : Description of Remedy Program : Autocar will voluntarily initiate an owner notification and recall of all affected vehicles. Autocar will distribute to owners of affected vehicles an Owner Notification Letter, which will describe the defect and provide instructions for scheduling the inspection/repair of the vehicle at no cost to the vehicle’s owner. The owner letter will instruct vehicle owners who have paid to have this condition remedied prior to this campaign to seek reimbursement pursuant to Autocar’s General Reimbursement Plan, on file with the agency pursuant to 49 C.F.R. 573.6(c)(8)(i) and 49 C.F.R 573.13. How Remedy Component Differs from Recalled Component : A hill start aid system will be installed at no charge. Identify How/When Recall Condition was Corrected in Production : The units involved were custom manufactured for one specific customer. Recall Schedule : Description of Recall Schedule : The dealer and customer notifications will begin January 27, 2022 and end January 25, 2022 Planned Dealer Notification Date : JAN 24, 2022 – JAN 25, 2022 Planned Owner Notification Date : JAN 24, 2022 – JAN 25, 2022 * NR – Not Reported
