Turn the main battery disconnect switch to the “OFF” position. 3. Locate the steering gear and steering gear serial number and part number located on the lip of the steering gear. See Figure 1. Use Steps 1 to 9 in the Identification Guidline for Sheppard Steering Gears in Appendix A to identify the serial number and part number on the steering gear. It will look something like 21D12345 or 22D12345 depending on what year the steering gear was manufactured and may have a -C at the end.  NOTE: Once you have the serial number use the recall website to access the Sheppard Steering Gear Classification Tool. https://recall.rhsheppard.com/USA/en/USD You can input your information and select New Flyer from the drop down on the left and enter the steering gear serial number on the right. Make sure you are omitting the -C at the end if required. The classification tool will give you a “Suspect” or “Good” response. If a “Not Found” response is given, check the number again and if it still will not match, contact Troy Stutsky @ serviceorganization_powertrain&systems@newflyer.com.

NEW FLYER. Wltii IMPORTANT SAFETY RECALL NOTICE 02 September 2022 Subject: Motor Vehicle Safety Recall 22V-637 Sheppard Steering Gear To Whom it May Concern: This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. New Flyer of America Inc. (“New Flyer”) has decided, that a manufacturing defect which relates to motor vehicle safety, may exist on the following New Flyer transit vehicles operated by Make: New Flyer Model: SR2684 2022 XD40 VIN & Unit Number: 5FYD8FV04NF105067 2205 5FYD8FV0XNF105073 2211 New Flyer has become aware of a potential defect with M110P Steering Gears manufactured by RH Sheppard Co., Inc. (RH Sheppard). RH Sheppard has declared an Equipment Recall (22E-047) with the U.S. DOT National Highway Traffic Safety Administration (NHTSA). This recall affects specific steering gears manufactured between June 1, 2021 and 10 February 2022. RH Sheppard has informed New Flyer that a small number of steering gears were assembled without the required number of recirculating balls. The recall population was determined by identifying the oldest production lot associated with a gear failure and including all production from that lot to the date in February 2022 when the improvements in the assembly process were instituted. A steering gear with fewer than the required number of recirculating balls may bind when loads are applied. In some cases, the balls may align on the same side of the gear’s worm-shaft and concentrated loads may cause the gear’s internal parts to fracture resulting in loss of vehicle steering. A loss of steering increases the likelihood of a collision. Preceding the internal fracture, the steering may be perceived as strained by the driver. No audible or visual warning is available. RH Sheppard estimates the repair time to be approximately 4.5 hours, excluding vehicle and shop logistics. Parts and labor required to accomplish the recall will be provided by RH Sheppard at no cost with labour reimbursement through the normal New Flyer warranty claim process. Please contact your New Flyer Regional Product Support Manager Terry Kotnarowski, to coordinate the recall action. If you are a lessor of vehicles which are identified above, it is required that any vehicle lessor receiving this recall notice must forward a copy of this notice to the lessee within ten days. If you no longer own this vehicle, or it has been removed from operation permanently, please inform the undersigned. If you had this corrective action performed before you received this letter, you may be eligible to receive reimbursement for the cost of obtaining a pre-notification remedy of the problem associated with this recall. If you have additional questions or concerns with regards to this recall or the way in which it was conducted, you may want to contact: Administrator, National Highway Traffic Safety Administration, 1200 New Jersey Ave. SE, Washington, DC, 20590, Or call 1-888-327-4236 (TTY: 1-800-424-9153); or go to http://www.safercar.gov. We regret any inconvenience which this action may cause you. However, we are concerned about the safety of your passengers and employees. Thank you for your attention to this important matter. Sincerely, NEW FLYER OF AMERICA INC. By: Jim Johnson Vehicle Safety & Regulatory Compliance Manager (256) 453-7181 cc: Scott Halbesma, Vice President, Customer Care Terry Kotnarowski – Regional Product Support Manager Attachment: ITS-60505

A steering gear with fewer than the required number may bind when loads are applied. In some cases, the balls may align on the same side of the worm shaft and concentrated loads may cause the gear’s internal parts to fracture, resulting in a loss of vehicle steering. (Refer to 22E-047) FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : Loss of steering increases the likelihood of a crash. (Refer to 22E-047) Description of the Cause : An anomaly in the steering gear recirculating ball insertion operation occurred during assembly. Subsequent rework processes and inspections did not detect the missing recirculating balls (refer to 22E-047). Identification of Any Warning that can Occur : Preceding the internal fracture, the steering may be perceived as strained by the driver. No audible or visual warning is available (refer to 22E-047) Involved Components : Part 573 Safety Recall Report 22V-637 Page 4 The information contained in this report was submitted pursuant to 49 CFR §573 Component Name 1 : Sheppard Model M110P Component Description : Steering Gear Component Part Number : Various Supplier Identification : Component Manufacturer Name : R.H. Sheppard Co. Inc. Address : 400 Pine Street Hanover Pennsylvania 17331 Country : United States Chronology : On 4 August 2022 New Flyer was contacted by the Trends Analysis Division regarding New Flyer’s response to Equipment Recall 22E-047. At that time New Flyer was unaware of the recall and immediately contacted RH Sheppard. By 10 August 2022, New Flyer had sufficient information from RH Sheppard to try and determine the affected population of production vehicles. On 17 August 2022 the New Flyer executives decided that a vehicle recall would be declared with NHTSA. A vehicle recall was submitted to the ODI on 24 August 2022. Description of Remedy : Description of Remedy Program : A technical instruction has been developed to inspect and replace the steering gear if required. The parts and labor related to the inspection and repair will be provided free of charge and can be reimbursed through the normal New Flyer Warranty system. How Remedy Component Differs from Recalled Component : The remedy component was assembled after the recall condition was corrected in production when additional controls were put in place. The remedy component has been verified to have the correct number of recirculating balls. Each remedy component is identifiable by an imprinted unique serial number. (Refer to 22E-047) Part 573 Safety Recall Report 22V-637 Page 5 The information contained in this report was submitted pursuant to 49 CFR §573 Identify How/When Recall Condition was Corrected in Production : On Feb 10, 2022 the recirculating ball insertion process control was enhanced. Additional process controls and inspectors were added to the process to verify that the correct number of recirculating balls in each steering gear. (Refer to 22E-047) Recall Schedule : Description of Recall Schedule : New Flyer has no Dealer Network. Customer notification will begin as soon as the customer letter is approved by the ODI. Planned Dealer Notification Date : SEP 01, 2022 – SEP 01, 2022 Planned Owner Notification Date : SEP 01, 2022 – OCT 21, 2022 * NR – Not Reported
