OMB Control No.: 2127-0004 Part 573 Safety Recall Report 23E-015 The information contained in this report was submitted pursuant to 49 CFR §573 Manufacturer Name : Bendix Commercial Vehicle Systems, LLC Submission Date : FEB 14, 2023 NHTSA Recall No. : 23E-015 Manufacturer Recall No. : NR Manufacturer Information : Manufacturer Name : Bendix Commercial Vehicle Systems, LLC Address : 35500 Chester Rd Avon OH 44011 Company phone : 440-329-9000 Population : Number of potentially involved : 836 Estimated percentage with defect : 2 % Equipment Information : Brand / Trade 1 : Intellipark PMV Model : Towing Variant Part No. : K206667R000 Size : NR Function : Park Brake Descriptive Information : The recall population is the entire production of the Intellipark Towing Park Brake Module (PVM). The Towing PVM differs from the Non-towing PVM in that it has two channels to control the tractor and the trailer park brakes. The Non-towing PMV has only one channel to control the park brakes as typical on a truck or bus. The Non-towing PMV does not contain the defect. Production Dates : FEB 01, 2019 – FEB 06, 2022 Description of Defect : Description of the Defect : The Intellipark Tractor Park Valve Module (PVM) may intermittently become stuck in the un-parked position and may not transition from un-parked to parked when the Park Switch is pulled on the vehicle dash board. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : An Intellipark PVM that intermittently becomes stuck in the un-parked position does not allow the vehicle spring brakes to exhaust when the driver pulls the Park Switch. The vehicle must be parked by depleting air storage by fanning-down the air brake system with the service brake pedal. If a driver does detect the Intellipark PVM malfunction indications and does not properly fan down the brakes, the vehicle may unintentionally move which increases the likelihood of a crash. Description of the Cause : Mechanical components in the PVM that are at the upper limit of the design Part 573 Safety Recall Report 23E-015 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 specification and other tolerance stack-ups allow for excessive internal air leakage. The internal leakage does not allow pressure to build properly when the pilot solenoid is activated. Identification of Any Warning that can Occur : Park Indication LEDs on the park switch remain off after the Park Switch is pulled indicating that the spring brake system has not exhausted and the vehicle is not parked. Audible exhaust sounds that typically are hear as an air-braked vehicle is park will not be hear indicating that the vehicle has not parked. The vehicle manufactures have implemented dash displays indications and alerts indicating that the vehicle has not parked in response to pulling the Park Switch.

1 April 06, 2023 Via USPS Delivery Name Title Company Street Address1 Street Address 2 City, State ZIP Code Dear Business Colleague: IMPORTANT RECALL INFORMATION – RESPOND IMMEDIATELY This is to inform you that Bendix Commercial Vehicle Systems LLC (Bendix) notified the National Highway Traffic Safety Administration (NHTSA) of the start of a voluntary safety recall campaign involving the Bendix® Intellipark® Tractor (Towing) Park Valve Module (PVM). The recall has been assigned number 23E015. A copy of our February 14, 2023, Defect and Noncompliance Information Report submission to NHTSA can be found on the NHTSA website (https://www.nhtsa.gov/recalls) under recall number 23E015. As required by law, Bendix provided NHTSA a list of all vehicle manufacturer customers to whom Bendix sold the affected product. <> is one of the customers that may be affected by this recall. IMPACTED PRODUCT This recall includes the Bendix Intellipark Towing Park Valve Module. The recall population is the entire production of this PVM – February 1, 2019, to February 6, 2023, inclusive. Bendix Intellipark Towing PVMs produced after February 6, 2023, do not contain the defect and are not part of the recall. This action does not affect Bendix Intellipark Non-Towing Park Brake Modules. The affected Towing PVM differs from the Non-Towing PVM in that it has two channels to control the tractor and the trailer park brakes. The non-towing PVM has only one channel that controls the park brakes (as typical on a truck or bus). PROBLEM DESCRIPTION Bendix has determined that the Bendix Intellipark Towing Park Valve Module (PVM) may intermittently become stuck in the un-parked position and may not transition from un-parked to parked when the park switch is pulled on the vehicle dash. Remaining in the un-parked position does not allow the vehicle spring brakes to exhaust when the driver pulls the park switch. As a result, the vehicle must be parked by depleting air storage by fanning down the air brake system with the service brake pedal. 2 Park indication LEDs on the vehicle dash Park Switch that remain off after the park switch is pulled, indicate that the spring brake system has not exhausted, and the vehicle is not parked. In addition, audible exhaust sounds typically heard when an air-braked vehicle is parked are absent, indicating that the vehicle has not parked. If a driver does not detect the Bendix® Intellipark® Towing PVM malfunction indications noted above, and does not properly fan down the brakes, the vehicle may unintentionally move, increasing the potential risk of a crash. WHAT WE WILL DO Bendix Commercial Vehicle Systems LLC will provide <> with a no-cost remedy and remedy instructions for this issue. The remedy involves removing and replacing the Intellipark Towing PVM built before February 6, 2023, with the remedy replacement Intellipark Towing PVM produced after February 6, 2023. WHAT YOU NEED TO DO First, we are providing you with this information to enable your business to determine whether there is a safety related defect on your vehicles where the PVM has been installed. Based on your determination, you may need to file a Defect and Noncompliance Report to the National Highway Traffic Safety Administration (NHTSA) with respect to new motor vehicles with an affected Bendix® Intellipark® Tractor (Towing) Park Valve Module (PVM) sold in the United States. A similar notification may be required to Transport Canada for all impacted vehicles sold in Canada.  Our records indicate that <> purchased affected Intellipark® PVMs from Bendix. To assist you in this recall, attached is a list of the affected Bendix Intellipark Tractor (Towing) Park Valve Modules (PVMs) – by part number and ship date – purchased by your company. We regret the inconvenience that may result from these circumstances, and we sincerely appreciate your understanding and cooperation in this matter. If you have any questions or require more information, please do not hesitate to reach out to your Bendix Account Manager directly. Sincerely, William P. Amato Director – Product Safety, Warranty, and Advanced Quality Encl.

Part 573 Safety Recall Report 23E-015 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 2/7/23 – Bendix PIC determines that a safety defect exists. Description of Remedy : Description of Remedy Program : The defect remedy program includes removing and replacing the Intellipark PVM and replacing it with a PVM without the defect. The PVM assembly is replaced as a whole unit and is not opened or serviced in the field. Bendix will provide the remedy PVM to the vehicle manufacturer. The vehicle manufactures will contact the vehicle owners. The remedy will be provided at no cost to the vehicle owner or vehicle manufacturer. Replace time is estimated at two hours though this depends on specific component locations on the vehicle. How Remedy Component Differs from Recalled Component : The remedy components include improved dimensional controls and Oring squeeze which eliminates the potential internal leak. The recalled components do not contain these improvements. The remedy component is identified by an updated part label and green marking visible on the exterior of the part to avoid confusion. Identify How/When Recall Condition was Corrected in Production : Production of the Tractor PVM has stopped once the defect was detected. Production resumed only after the internal components were improved to include improved dimensional controls and O-ring squeeze which eliminates the potential internal leak. Recall Schedule : Description of Recall Schedule : All Customers will be notified in writing on or before the notification End Date.
